1.0 INTRODUCTION & PURPOSE

1.1 Introduction

On behalf of 178 Warburton Limited Partnership, C.T. Male Associates Engineering,

Surveying, Architecture, Landscape Architecture & Geology, D.P.C. (C.T. Male) has

prepared this Remedial Work Plan (RWP) pursuant to the New York State Department

of Environmental Conservation (DEC) Brownfield Cleanup Program (BCP). This RWP

pertains to the property known as the Cottage Place Gardens Phase 5 Parcel Site (Site

No. C360161) located at 8 Cottage Place and 178 Warburton Avenue in the City of

Yonkers, Westchester County, New York (herein the “Site”). A Site Location Map is

presented as Figure 1.

178 Warburton Limited Partnership entered into a Brownfield Cleanup Agreement

(BCA) with the DEC in December 2017 (BCA Index No.: C360161-09-17), to remediate

an approximate 1.471 acre property to Unrestricted Use as defined in 6 NYCRR Part 375.

178 Warburton Limited Partnership is a Volunteer in the BCP. When redevelopment is

completed, the Site will contain multi-family residential housing with associated

parking and green spaces.

1.2 Purpose and Goal

The purpose of the RWP is to provide a conceptual plan for the selected remedy for the

Site. With concurrence from DEC, the preparation of a formal remedial design work

plan is not planned considering that the remedial action (generally excavate and

properly dispose) is a presumptive remedy, as defined at DER-10-1.3(b)46 and 6

NYCRR Part 375-1.2(ai).

The goal of this RWP is to provide guidance to 178 Warburton Limited Partnership’s

design and construction team to supplement the project’s technical specifications, and

1 The area of the Site is depicted as 1.54 acres in the BCA. To accommodate the proposed redevelopment goals for the Site and its north adjoining Cottage Place Gardens Phase 3 BCP Site, the boundaries of the 8 Cottage Place portion of the Site were reconfigured; reducing the size of the Site from 1.54 to 1.47 acres. The Site’s reconfiguration is memorialized in the BCP Application to Amend Brownfield Cleanup Agreement and Amendment, which was executed by NYSDEC on June 15, 2018.

bidding and construction documents. The remedial action requirements will be

incorporated into the overall Site redevelopment project, as necessary, to comply with

the BCP. It is the responsibility of the Volunteer to provide this RWP to the general

contractor in order to coordinate and integrate remedial and Site redevelopment

activities and ensure adherence by the contractor to this RWP. Prior to the start of Site

redevelopment activities, the Contractor shall indicate in writing their receipt and

review of the RWP.

1.3 Nature and Extent of Contamination

The nature and extent of Site contaminants was characterized through the completion of

a DEC-approved Remedial Investigation (RI) of the Site in April 2018. The RI analytical

data is supplemented with analytical data of fill/soil and groundwater sampled in 2014,

2016 and 2017 as part of Phase II Environmental Site Assessment (ESA) investigations of

the Site completed by C.T. Male, and analytical data of fill/soil samples from

confirmatory post-excavation sidewall samples collected as part of the remedial action

of the Site’s north adjoining Cottage Place Gardens Phase 3A BCP Parcel (C360150).

The aforementioned sidewall samples are representative of fill material along the Site’s

northern boundary.

The following sections summarizes the contaminants of concern (COCs) encountered in

the Site’s media and potential source areas for the contaminants.

1.3.1 Contaminants of Concern in Fill Material Mantling the Site

Analytical results of fill/soil samples collected during previous Phase II ESA

investigations and the Remedial Action at the CPG Phase 3A BCP site identified six (6)

VOCs, 10 SVOCs, three (3) pesticides and seven (7) metals at concentrations exceeding

Soil Cleanup Objectives (SCOs) for Unrestricted Use Sites promulgated at 6 NYCRR

Part 375.

The highest frequency of detections were for the SVOCs benzo(a)anthracene,

benzo(a)pyrene, benzo(b)fluoranthene, chrysene and indeno(1,2,3-cd)pyrene which

were detected in eastern and western portions of the Site; and the metals lead, mercury

and zinc which were detected across the Site. The VOCs, with the exception of acetone,

were petroleum related and were confined to the western portion of the Site addressed


3

as 178 Warburton Avenue that was formerly developed with a gasoline station and

vehicle repair facility. The sampling locations and concentration ranges for the COCs in

fill material are depicted on Figure 3: Analytes in Fill/Soil Exceeding SCGs.

The Site was assigned NYSDEC Spill No. 1610948 on March 7, 2017 pursuant to

subjective impacts in the Site’s fill/soil, which included elevated photoionization

detector (PID) readings and petroleum-type odors. The impacts were confined to the

western portion of the Site (178 Warburton Avenue). The spill was administratively

closed by NYSDEC on April 9, 2018. The impacts to fill/soil within the western portion

of the Site will be addressed as part of the Site remedy, which will include the

excavation and off-site disposal of these impacted fill/soil and the capture and

treatment and/or off-Site disposal of groundwater present during the removal of

impacted soils/fill.

1.3.2 Contaminants of Concern in Native Soil Underlying the Fill Material

There were no COCs in native soil underlying the fill material based on analytical

results for native soil samples collected during the RI.

1.3.3 Contaminants of Concern in Groundwater

Groundwater is impacted above regulatory criteria by eight (8) VOCs, eight (8) SVOCs

and nine (9) metals. The majority of the contaminants (7 VOCs, 6 SVOCs and 8 metals)

were encountered in groundwater samples collected from four (4) monitoring wells

within the western portion of the Site at 178 Warburton Avenue. The VOC

contaminants within this portion of the Site are petroleum related. The contaminants of

concern in groundwater within the western portion of the Site include the VOCs

benzene, ethylbenzene, isopropylbenzene, methyl tert butyl ether (MtBE), toluene, o-

xylene and p/m-xylene; the SVOCs benzo(a)anthracene, benzo(b)fluoranthene,

benzo(k)fluoranthene, chrysene, indeno(1,2,3-cd)pyrene, and naphthalene; and the

metals barium, chromium, copper, iron, lead, manganese, nickel and sodium.

Contaminants in groundwater samples collected from two (2) monitoring wells on

southern portions of the Site, up-gradient and to the east of the 178 Warburton Avenue

portion of the Site included the VOC acetone, the SVOC phenol and the metals

chromium, iron, lead, manganese, mercury and sodium. The sampling locations and


4

concentration ranges for the COCs in groundwater are depicted on Figure 4: Analytes

in Groundwater Exceeding SCGs.

1.3.4 Interim Remedial Measures

A non-emergency interim remedial measure (IRM) was conducted on the western

portion of the Site addressed as 178 Warburton Avenue that was formerly used as a

gasoline station and vehicle repair facility. An IRM Work Plan (dated June 7, 2018)

detailing the activities to be conducted during the IRM was prepared by C.T. Male and

approved by NYSDEC on July 2, 2018. The IRMs included profiling and disposal of the

contents of an aboveground tank, drums and containers located in and around the

building (completed on July 11, 2018); asbestos abatement (completed May 2018) and

demolition (completed March 2019) of the building; and paving the Site with an asphalt

binder (completed on July 10, 2019). A report detailing the IRM will be submitted to

NYSDEC under separate cover.

1.3.5 Potential Sources for Contaminants of Concern

The primary source of Site contaminants is the uncontrolled fill material that mantles

the Site. VOCs, SVOCs, pesticides and metals are present in fill material at

concentrations exceeding Unrestricted Use SCOs.

A secondary source of Site contaminants is the former usage of the western portion of

the Site addressed as 178 Warburton Avenue as a gasoline station and vehicle repair

facility. Petroleum-type contaminants in fill/soil and groundwater within this portion

of the Site may be attributed to former floor drains and hydraulic lifts within the former

building and/or residual impacts from the removal of 11 petroleum underground

storage tanks (USTs) and subsequent removal of 850 tons of petroleum impacted soils

from 2006 to 2008.

Petroleum-type impacts were not encountered in media samples collected in the

vicinity of the two (2) existing out of service heating oil USTs located to the east of

Building 12.

1.3.6 Remedial Action Objectives

Based on the findings and results of the RI, remedial action objectives (RAOs) have been

identified for the Site as presented in the following table.

Affected Media Remedial Action Objectives

Fill/Soil

RAOs for Public Health Protection

• Prevent ingestion and direct contact with contaminated fill/soil.

• Prevent inhalation of, or exposure to, contaminants volatilizing from

contaminated fill/soil.

RAOs for Environmental Protection

• Prevent migration of contaminants that would result in groundwater

contamination

Groundwater

RAOs for Public Health Protection

• Prevent ingestion of groundwater containing contaminant levels

exceeding drinking water standards.

• Prevent contact with, or inhalation of, volatiles emanating from

contaminated groundwater.

RAOs for Environmental Protection

• Restore groundwater, to the extent practicable, to pre-disposal/pre-

release conditions.

• Remove the sources of groundwater contamination.

Soil Vapor

RAOs for Public Health

• Mitigate impacts to public health resulting from existing, or the potential

for, soil vapor intrusion into buildings at the Site.

Surface Water Not Applicable

Sediment Not Applicable

1.4 Remedial Action Approach

The remedial action for the Site is generalized as decommissioning of monitoring wells;

closure by removal of bulk petroleum USTs; closure by removal of underground

hydraulic lifts and drainage structures (if present); fill/soil excavation and off-site


6

disposal; and groundwater evacuation/dewatering and treatment/disposal as

necessary to facilitate the removal of impacted soil/fill below the water table.

A soil vapor intrusion (SVI) evaluation will be completed prior to the submission of the

Final Engineering Report. The SVI evaluation will include an assessment of pre- and

post-remediation soil and groundwater data, evaluation of the effectiveness of the

remedial action relative to SVI, and evaluation of the on-site buildings relative to SVI.

The need for sub-slab soil vapor and indoor/outdoor air quality samples will be

evaluated during completion of the SVI evaluation. No active vapor intrusion

mitigation measures are anticipated at the Site pending on the remedial action

achieving the RAOs for soil vapor.

The depth to groundwater beneath the Site is estimated at 11 feet beneath the ground

surface (bgs) in the eastern portion of the Site addressed as 8 Cottage Place, nine (9) feet

to 12.5 feet bgs in the central portion of the Site addressed as 8 Cottage Place and two

(2) feet bgs in the western portion of the Site addressed as 178 Warburton Avenue.

Sheeting/shoring at the property boundaries of the 178 Warburton Avenue parcel will

likely be required to effectively remove the impacted fill/soil below the depth

groundwater has been historically encountered.

1.4.1 Decommissioning of Monitoring Wells

Existing monitoring wells within the Site will be decommissioned in accordance with

DEC Policy CP-43: Groundwater Monitoring Well Decommissioning Policy, dated

November 3, 2009. The monitoring wells that will be decommissioned are depicted on

Figure 2 as 178MW01, 178MW02, 178MW03, 178MW04, MW-B, MW-E, MW-K, MW-P

and MW-Q. Monitoring wells to be decommissioned will be tremi-grouted from the

bottom of the monitoring well to the anticipated bottom of the remedial excavation.

The monitoring well construction logs are presented in Appendix C.

1.4.2 Closure of Bulk Storage Tanks

Two (2) known USTs are located beneath asphalt pavement adjacent east of Building 12

(see Figure 2). The tanks reportedly contained fuel oil for boilers in the basement of

Building 12. The tanks were reportedly rendered out of service approximately five (5)

to 10 years ago when the Site converted to natural gas.


7

The following general procedures will be followed for closure by removal of the known

bulk storage tanks and any other tanks that may be encountered during the remedial

action.

-Notify NYSDEC of closure activities through the use of a “Pre-Work Notification for

Bulk Storage (PBS or CBS) Tank Installation or Closure” form.

-Notify the Westchester County Department of Health of the tank closures.

-The tank closure contractor will need to obtain a Minor Alteration permit from the City

of Yonkers Department of Housing and Buildings prior to the tank closures.

-Closure of the tanks and associated appurtenances (product, fill and vent piping,

underground electric, concrete pump island, etc.) will conform to applicable sections of

DER-10, NYSDEC Petroleum Bulk Storage regulations 6 NYCRR Part 613-2.6, Out-of-

service UST Systems and Closure, and the City of Yonkers Department of Housing and

Buildings.

-Any soil, fill, concrete and/or asphalt overlying and/or surrounding the tanks will be

removed to allow access to the tanks. The contents of the tanks will be removed and

transported to a disposal facility permitted to accept this waste. If in small quantities,

the liquids and tank bottoms may be temporarily stored in labeled DOT approved 55-

gallon drums for disposal at a permitted and approved treatment, storage and disposal

facility (TSDF). Oil soaked rags, clothing and polyethylene (i.e., PPE) will also be

placed in a labeled DOT approved 55-gallon drum for off-site disposal.

-The tanks will be accessed either through tank man-ways (if present) or a hole will be

cut in the tank to allow access for removal of the tank contents and cleaning while the

tanks remains in-place. Polyethylene will be placed on the ground adjacent to the tank

openings to mitigate contamination of the ground surface when cleaning the tank

interiors. Prior to opening, cutting or entering the tanks for cleaning, the Contractor

will assess and document the atmospheric conditions within the tanks. The Contractor

will follow confined space entry procedures in accordance with 29 CFR Part 1910.146

for tank cleaning by appropriately trained personnel.

-The tanks will be cleaned and purged of any vapors in accordance with all applicable

regulations in addition to 29 CFR Part 1910.146. The tanks will be rendered unusable


8

on-site by cutting a hole in the end of the tank after removal from the ground and/or

vault, if not already done so for access. The tank, distribution and vent piping, and

associated equipment will be properly disposed of off-site at a steel recycling facility.

Records of metal disposal/recycling will be provided to the Remediation Engineer.

-Fill/soil samples will be collected for laboratory analyses after removal of the tanks, as

described in Section 5.1 of this document.

-The waste contents of the tanks and associated piping and equipment, and cleaning

wastes will be properly managed and disposed of off-site at an approved and permitted

TSDF. The wastes will be transported by a 6 NYCRR Part 364 transporter permitted to

transport these wastes, and disposed of at a facility permitted to accept the waste being

disposed of. Should out-of-state facilities be identified as proposed disposal facilities,

permits for the facilities by the corresponding regulatory agency must be provided to

the Remediation Engineer and NYSDEC for review and approval prior to material

exportation. The disposal facility and general type of waste will be specifically listed on

the transporter’s permit.

-Registration of the tanks as “closed-removed” in accordance with NYSDEC Petroleum

Bulk Storage regulations, the City of Yonkers Department of Housing and Buildings

and the Westchester County Department of Health.

1.4.3 Closure By Removal Of Underground Hydraulic Lifts And Drainage

Structures

Evidence of up to four (4) former hydraulic lifts and square-type floor drains were

identified within the concrete slab of the former building addressed as 178 Warburton

Avenue (see Figure 2). The lifts and floor drains appear to have been filled at least in

part with concrete.

One (1) floor drain and a concrete floor slab cut-out believed to have been used for

drainage were identified within the northeastern and eastern portions of the concrete

slab of the former building at 178 Warburton Avenue.

The following general procedures will be followed for closure by removal of the

underground hydraulic lifts and drainage structures during the remedial action.


9

-The concrete slab will be removed in a controlled manner so as not to damage the

hydraulic lifts and drainage structures.

-The hydraulic lifts and all appurtenances (piping, electrical, hydraulic oil reservoirs,

etc.) will be removed and staged on poly and covered. The Remediation Engineer’s

field representative will assess the hydraulic lifts for remaining fluids. If the hydraulic

lifts and appurtenances do not contain residual fluids, they will be disposed of off-site

at a metal recycling facility. If the hydraulic lifts and appurtenances contain fluids, the

fluids will be drained/emptied into 55-gallon drums and remain on-Site pending

profiling and off-site disposal at an approved and permitted TSDF. Once emptied, the

cylinders/ apparatus will be disposed of off-site at a metal recycling facility. Approval

will be obtained from the Remediation Engineer and the DEC Project Manager prior to

disposal off-site.

-The drainage structures will be assessed by exposing and tracing any connecting

piping or other conveyance attached to the drainage structures to their terminus. The

entirety of the drainage structure systems (drain receptacles and conveyances) will be

removed and staged atop poly and covered. The Remediation Engineer’s field

representative will assess the drainage structure systems for environmental impacts by

scanning the systems for organic vapors with a photoionization detector (PID) and via

visual observation. If the drainage systems do not appear impacted, they will be

disposed of off-site at a recycling facility. If the drainage systems appear impacted and

cannot be field cleaned/decontaminated, they will be profiled and disposed of off-site

at an approved and permitted TSDF. Approval will be obtained from the Remediation

Engineer and the DEC Project Manager prior to disposal off-site.

-Fill/soil surrounding the hydraulic lifts and drainage structure systems will be

subjectively assessed by the Remediation Engineer’s field representative for organic

vapors employing a PID and via organoleptic (sight and smell) perception. Impacted

fill/soil will either be disposed of with the remaining fill/soil as part of the Site’s

overall remedial action or the impacted fill/soil will be staged atop poly and covered

pending profiling and off-site disposal at an approved and permitted TSDF. Approval

will be obtained from the Remediation Engineer and the DEC Project Manager prior to

disposal off-site.


10

1.4.4 Remediation of Impacted Fill/Soil

The following general procedures will be followed for the remediation of impacted

fill/soil mantling the Site.

-Fill/soil mixtures underlying the 178 Warburton portion of the Site are impacted by

petroleum and may need to be remediated separately from non-petroleum impacted

soil/fill mixtures mantling remaining portions of the Site.

-Excavation and off-site disposal of fill/soil mixtures mantling the Site from the ground

surface to depths ranging from approximately two (2) to 12 feet bgs. The remedial

excavation may also include the additional excavation of native soils that do not meet

SCOs for Unrestricted Use Sites based on analytical results of confirmatory post-

excavation sampling and analysis. The generalized excavation depths across the Site

are depicted on Figure 2. As depicted on the figure, impacted fill/soil within the

western portion of the Site at 178 Warburton Avenue will be excavated to an

approximate depth of 12 feet bgs (deeper excavation might be warranted in certain

areas) and impacted fill/soil within remaining portions of the Site will be excavated to

depths ranging from approximately four (4) to eight (8) feet bgs.

-The remedial excavation will extend horizontally to the Site boundaries or to the extent

feasible without compromising the integrity of roadways and/or structures on adjacent

properties and/or as limited by access restrictions from adjacent property owners. In

the event of not being able to extend excavations to the property boundaries, the limits

of the BCA will be adjusted accordingly via a BCA amendment.

-The vertical depths that fill and/or contaminants were encountered at each of the

boring locations completed during the RI and previous investigations of the Site are

depicted on Figure 2: Remedial Action Implementation.

It should be noted that the COCs identified as part of the RI are intended to provide a

general description of the contamination at the Site. The concentration ranges of COCs

identified at the sampling locations may be representative of COCs throughout the

Site’s media. Furthermore, both different types and different concentration ranges of

COCs may be encountered during characterization of the Site’s media for disposal

facility purposes.

-Any concrete from building remains in contact with fill/soil requiring remediation will

either be broken up and disposed of with the impacted fill/soil and/or the impacted


11

fill/soil will be removed from the concrete and disposed of as a separate C&D waste

stream. The disposal locations for both waste streams is required to the submitted to

the certifying Remediation Engineer and DEC Project Manager for approval prior to

removal from the Site.

-Other appurtenances that may be in contact with contaminated Site fill/soil include,

but are not limited to, asphalt access-ways and parking lots; concrete walkways,

stairways, retaining walls, bollards and curbing; subsurface portions of handrails, light

posts and signage, and underground utilities. These appurtenances, and any other

appurtenances encountered within the remedial excavation, may be disposed of as a

separate C&D waste stream provided that any fill/soil adhering to the appurtenances

are removed prior to the appurtenances leaving the Site for off-site disposal. The

disposal location will be required to the submitted to the certifying Remediation

Engineer and DEC Project Manager for approval prior to removal from the Site.

-Grossly impacted fill/soil, if any, (as defined at DER-10, Section 1.3, Item 23)

encountered in the excavation floor at the depth limits of the excavations will be further

excavated and staged on-site pending waste characterization and subsequent off-site

disposal. The extent of the grossly impacted fill/soil will be subjectively assessed by

the Remediation Engineer’s field representative using PID headspace analysis and

organoleptic (sight and smell) perception. Confirmatory post-excavation end-point

samples will be collected for laboratory analysis to confirm removal of the material to

the prescribed cleanup levels.

-The possibility exists for the addition of chemical and/or biological amendments to

open excavation areas to aid in the degradation of petroleum-type contaminants in soil

and groundwater. The need for the application of amendments will be determined

during the implementation of the remedial action and in consultation with NYSDEC.

NYSDEC will be provided with a scope of work for the application of the amendments

prior to its implementation for review and approval.

1.4.5 Groundwater Evacuation and Treatment

The COCs in groundwater beneath the portion of the Site addressed as 8 Cottage Place

include acetone, phenol, and the metals chromium, iron, lead, manganese, mercury and

sodium. Iron and manganese are viewed as naturally occurring in the environment.

Sodium is attributed to the application of snow/ice salt at the ground surface and is not


12

viewed as a COC. Groundwater was measured from approximately nine (9) to 12.5 feet

bgs within this portion of the Site.

The COCs in groundwater beneath the portion of the Site addressed as 178 Warburton

Avenue include petroleum related VOCs, SVOCs and metals. Groundwater was

measured at approximately two (2) feet bgs within this portion of the Site.

Groundwater will likely be encountered during excavation of impacted fill/soil in the

western portion of the Site addressed as 178 Warburton Avenue and may be

encountered during excavation of impacted fill/soil in remaining eastern portions of

the Site. The following general procedures will be followed for groundwater

evacuation and treatment during the remedial action.

-Groundwater entering the excavations during fill/soil remediation within portions of

the Site east of the 178 Warburton Avenue parcel will be evacuated and transferred into

a temporary holding tank to the extent necessary to remove impacted soils. If limited in

volume, the groundwater may be evacuated from the excavations as necessary via a

vacuum (Vac) truck and transported for off-site disposal at an approved and permitted

TSDF. The disposal location will be required to the submitted to the certifying

Remediation Engineer and DEC Project Manager for approval prior to removal from the

Site.

-On-site groundwater treatment will be implemented when one or a combination of the

following conditions are observed: laboratory testing has identified the presence of

petroleum chemical constituents in the groundwater above applicable discharge limits

(below); a petroleum film/sheen is observed on the groundwater surface; petroleum

odors are noted in the groundwater; groundwater comes into contact with petroleum

contaminated soil; and/or testing for approval to discharge groundwater to the

municipal storm/sewer system shows contaminants above applicable discharge limits

(below).

-Treated groundwater will be discharged to the closest connection to the municipality’s

sanitary collection system (i.e. sanitary lines along Warburton Avenue, Irving Place

and/or Wood Place). Prior to discharge, the remediation contractor will be responsible

for obtaining a wastewater discharge permit from the Westchester County Department

of Environmental Facilities (DEF). Pre- and post-treatment sampling will be performed

of the water treatment system prior to discharging to the sewer to confirm that the

discharge meets the limits established by the Westchester County DEF. Subsequent


13

sampling and analysis of the treatment system will be performed at sampling

frequencies required by the Westchester County DEF. DEC will be provided with the

dewatering and treatment system design and plan prior to its implementation.

-Groundwater that may be encountered in the eastern portions of the Site (other than

the 178 Warburton Avenue parcel) that does not appear impacted and constituents are

below the above applicable discharge limits will be managed on-site. Approval will be

obtained from the Remediation Engineer and NYSDEC prior to managing groundwater

on-site (as determined by laboratory testing and absence of sheen and odors).

1.4.6 Post-Remedial Action Groundwater Monitoring and/or Treatment

Site investigations have shown that groundwater has been impacted by petroleum-

related VOCs, SVOCs and metals. These impacts are predominantly confined in

groundwater beneath the 178 Warburton Avenue portion of the Site. The proposed

remedy that will be implemented to address impacted groundwater within this portion

of the Site will include the following.

-Four (4) monitoring wells are anticipated to be installed at hydraulically down-

gradient locations prior to the commencement of the remedial action. Two (2)

monitoring wells are anticipated to be installed along the western boundary within the

178 Warburton Avenue portion of the Site (to be installed only if the existing

monitoring wells at the 178 Warburton Avenue parcel are not suitable for groundwater

sampling). Two (2) monitoring wells will be installed off-site to the west of the western

property boundary of the 178 Warburton Avenue portion of the Site. The approximate

monitoring well locations are depicted on Figure 2.

-The soil borings for installation of the monitoring wells will be completed utilizing

direct-push methods. The monitoring wells will be constructed of one (1) to 1.25-inch

diameter PVC riser and screen. The screened portions of the wells will straddle the

water table five (5) feet above and five (5) feet below the water table. The monitoring

wells will be protected at the surface with flush-mounted enclosures set in concrete.

-Groundwater samples will be collected from the monitoring wells to gage

groundwater quality prior to initiation of the remedial action within the 178 Warburton

Avenue portion of the Site. The monitoring wells will be developed, purged and

sampled in accordance with the Field Sampling Plan (FSP) presented in Appendix A of


14

the June 30, 2017 (Revised January 2018) Remedial Investigation Work Plan (RIWP).

The groundwater samples will be analyzed for the Target Compound List (TCL) for

VOCs and SVOCs, and the Target Analyte List (TAL) for metals.

-The remedial action will be implemented, which will include excavation and off-site

disposal of impacted fill/soil; excavation dewatering, treatment and off-site disposal;

the closure by removal of remaining hydraulic lifts and drainage structures (if

encountered); and the backfilling of the excavations with clean, imported fill meeting

soil cleanup objectives (SCOs) for Unrestricted Use Sites promulgated at 6 NYCRR Part

375.

-The possibility exists for the addition of chemical and/or biological amendments to


and groundwater. The need for the application of amendments will be determined in

consultation with NYSDEC. NYSDEC will be provided with a scope of work for the

application of the amendments prior to its implementation for review and approval.

-Collection of groundwater samples post-remedial action. Groundwater samples will

be collected after completion of the remedial action to gage the effectiveness of the

remedial action on groundwater quality. A subset of the monitoring wells that were

destroyed/decommissioned during the remedial action will be replaced in-kind (unless

permission is granted by NYSDEC to waive the replacement of wells). Monitoring

wells to be replaced will be determined following remedial activities with approval of

NYSDEC. The monitoring wells will be developed, purged and sampled in accordance

with the FSP in the RIWP. The groundwater samples will be analyzed for the TCL for

VOCs and SVOCs, and the TAL for metals.

-The pre- and post-remedial action groundwater sampling results will be reviewed by

the Remediation Engineer and the Department to gauge the effectiveness of the

remedial action on groundwater quality. As a “Volunteer” in the BCP, 178 Warburton

Limited Partnership will only be responsible for remedial activities related to on-site

groundwater quality.

-Per 6 NYCRR Part 375-3.8(e)(1)(iii)(b), the Volunteer will make a good faith effort to

“demonstrate to the Department’s satisfaction that there has been a bulk reduction in

groundwater contamination to asymptotic levels”. Good faith efforts include closure by

removal of hydraulic lifts and drainage structures, closure by removal of known and


15

unexpected underground storage tanks, excavation and off-site disposal of impacted

HFM, evacuation and off-site disposal of groundwater entering the remedial

excavations, and the possible addition of chemical and/or biological amendments to


and groundwater.

For informational purposes, the following paragraphs provide information regarding

groundwater use restrictions within the City of Yonkers and the City of Yonkers potable

water source.

The Site and surrounding community are provided with public water that is furnished

by the City of Yonkers. Per Section 57-26 A: Water for Drinking or Domestic Purposes

of Part VI: Fire and Buildings of Article VII: Water Supply of the Code of the City of

Yonkers, “All water supply used for drinking purposes or domestic purposes, except

bottled water, shall be provided by the public water supply of the City of Yonkers, New

York.”

Private potable and/or domestic water wells are not permitted within the City of

Yonkers. Per Section 57-26 C: Water for Drinking or Domestic Purposes of Part VI: Fire

and Buildings of Article VII: Water Supply of the Code of the City of Yonkers, “Wells

are not permitted for drinking or domestic use and may not be physically connected in

any way to the public water supply system of the City of Yonkers.”

The City of Yonkers obtains its drinking water from the New York City Water Supply

System. Most of this water originates from two (2) protected watershed areas, the

Catskill and Delaware, located west of the Hudson River in upstate New York.

1.4.7 Remedial Investigation Derived Wastes

Investigation Derived Wastes (IDW) generated as a function of the RI includes 19, 55-

gallon drums containing drill cuttings from the soil borings, monitoring well

development and purge water, and decontamination water used for the

decontamination pad. The IDW will be characterized and disposed of off-site at an

approved and permitted TSDF in the event the IDW cannot be disposed with the

impacted fill/soil mixture at the approved off-site disposal facilities. The wastes will be

transported by a 6 NYCRR Part 364 transporter permitted to transport these wastes.

The drums are currently staged along the eastern exterior of Building 12.


16

1.5 Remedial Treatment Units

The entire Site, the limits of which are shown on Figure 2, is to be considered as one (1)

remedial treatment unit or area of concern.

The approximate vertical depths of fill material mantling the Site at each of the

sampling locations completed during the RI and previous investigations are

summarized on Figure 2.

The sampling locations, sampling depths and concentrations of contaminants in fill/soil

exceeding SCOs for Unrestricted Use Sites are summarized in Figure 3 in Appendix A.

1.6 Applicable NYS Standards, Criteria and Guidance (SCGs)

The applicable SCGs for each media type to be remediated during the remedial action

are summarized as follows:

1.7 Remedial Action Schedule

It is expected that the remedial action will be completed in two (2) phases as follows:

Phase I: Asbestos Abatement and Building Demolition

Phase I is anticipated to begin in late 2020 and should be completed in Spring/Summer

2021. Phase I will include the following tasks.

-Asbestos abatement and demolition of Buildings 4, 8 and 12 within the portion of the

Site addressed as 8 Cottage Place. Abatement of asbestos containing materials (ACM)

will be in accordance with the New York State Department of Labor (NYSDOL)

Industrial Code Rule (ICR) 56. The ACM abatement work activities will be managed

under the requirements of the NYSDOL rather than the DEC Division of Environmental

Remediation. As a note, asbestos abatement and demolition of the aboveground

portion of the building addressed as 178 Warburton Avenue within the western portion

of the Site was completed in March 2019 as part of a non-emergency interim remedial

measure (IRM). The former building’s concrete slab remains.

-Building foundation concrete (footers, walls and slabs) in contact with Site fill/soil will

either be addressed as part of the building demolition or will be left in place and

addressed as part of the remedial excavation. If removed as part of the building

demolition, methods will be employed to remove any soils adhering to the concrete

prior to the concrete leaving the Site for off-site disposal.

Phase II: Remedial Action

Phase II is anticipated to begin immediately following the asbestos abatement and

demolition phase, in Spring/Summer 2021 and should be completed during the Winter

of 2022. Phase II will include the following tasks.

-As a note, due to the Site’s redevelopment sequencing utilizing different contractors for

construction of the proposed building and a public park, different areas of the Site may


18

be remediated at different times. The goal will be to first begin remediation in the

western portion of the Site addressed as 178 Warburton Avenue.

-Decommissioning of monitoring wells within the Site boundaries that were installed

during previous investigations of the Site. These monitoring wells are identified as

178MW01, 178MW02, 178MW03, 178MW04, MW-B, MW-E, MW-K, MW-P and MW-Q

on Figure 2.

-Closure by removal of bulk USTs, hydraulic lifts and drainage structure systems.

-Excavation and off-site disposal of all fill/soil mixtures mantling the Site, and the

possible additional excavation of native soils that do not meet SCGs based on analytical

results of confirmatory post-excavation sampling. The remedial excavation will extend

to the boundaries of the Site. Fill/soil mixtures mantling the 178 Warburton Avenue

portion of the Site are impacted by petroleum. This phase of the remedial action is

anticipated to be completed in Summer/Fall 2021.

-Groundwater evacuation, characterization, treatment and/or off-site disposal as

necessary during the remedial excavation. Sheeting/shoring at the property

boundaries of the 178 Warburton Avenue parcel will likely be required to effectively

remove the impacted fill/soil below the depth groundwater has been historically

encountered.

-Possible addition of chemical and/or biological amendments to open excavation areas

within the 178 Warburton Avenue parcel to aid in the degradation of petroleum-type

contaminants in soil and groundwater.

-Backfilling of the Site with imported fill meeting SCOs for Unrestricted Use Sites. This

phase of the remedial action is anticipated to be completed in Winter 2022.

-Characterization (if needed) and off-site disposal of drummed investigation derived

wastes generated during the previous investigations and RI of the Site. The drummed

wastes are located along the eastern exterior of Building 12.

-Preparation and submission of the Final Engineering Report (FER), which is

anticipated to be completed during the Winter/Spring of 2022. The time lapse for

submission of the FER takes into account the time required for receipt of analytical


19

results of remedial excavation end-point sampling, data validation of the analytical

results, and review by the Volunteer. A more detailed remedial action schedule will be

provided to the DEC Project Manager after completion of field work associated with the

remedial activities.

-A SVI evaluation will be completed prior to the submission of the Final Engineering

Report. The SVI evaluation will include an assessment of pre- and post-remediation

soil and groundwater data, evaluation of the effectiveness of the remedial action

relative to SVI, and evaluation of the on-site buildings relative to SVI. The need for sub-

slab soil vapor and indoor/outdoor air quality samples will be evaluated during

completion of the SVI evaluation. No active vapor intrusion mitigation measures are

anticipated at the Site pending on the remedial action achieving the RAOs for soil

vapor.

1.8 Miscellaneous General Requirements

Prior to beginning construction of the remedial action (excluding the asbestos

abatement and building demolition phase), a pre-construction meeting will be held

with the DEC Project Manager, the Volunteer, the Remediation Engineer (C.T. Male),

the construction manager and the contractor/subcontractors designated to complete the

remedial action related work.

The hours of operation of the remedial construction work will conform to the City of

Yonkers construction codes. The DEC Project Manager will be notified of any variances

issued by the City of Yonkers.

1.9 Citizen Participation

Citizen participation will continue on this project as follows:

• Once the RWP has been finalized, a public notice fact sheet will be released by

the DEC before the start of the remedial construction work. The Decision

Document will be issued after the RWP is finalized.


20

2.0 TEMPORARY CONSTRUCTION FACILITIES

2.1 Site Security

The Site is an approximate 1.47 acre single lot that occupies the central portion of the

Cottage Place Gardens public housing complex addressed as 8 Cottage Place and 178

Warburton Avenue. The Site consists of three (3) multi-story residential apartment

buildings and the concrete slab remains of the former building addressed as 178

Warburton Avenue. The residential apartment building identified as Building 12 on

Figure 2 contains a boiler in its basement that is used to heat the apartment buildings

within the Site. These structures are surrounded with asphalt paved access-ways and

parking areas, concrete sidewalks, and landscaped areas. Currently, the Site is easily

accessible to residents of surrounding apartment buildings within the Cottage Place

Gardens complex and to the public from Warburton Avenue, Irving Place and Wood

Place; which are public streets.

As the Site is easily accessible to the public, construction fencing with lockable gate(s)

will be installed and maintained around the entire perimeter of the Site prior to the start

of the building asbestos abatement and demolition activities, and remain in-place

throughout the remedial action.

2.2 Trailers/Office Space

A construction office trailer(s) or nearby office space will be provided by the contractor

for use by the Remediation Engineer’s field representative and DEC personnel. The

space shall include a desk or table to work on and power to charge field monitoring

equipment daily. A minimum area, generally six (6) feet by six (6) feet, should be

sufficient.

2.3 Equipment Decontamination

Construction equipment that comes into contact with the Site’s contaminated fill and

soil, and potentially impacted groundwater, will be considered contaminated. Prior to

the equipment being demobilized from the Site or prior to entering an area deemed

clean by meeting applicable SCGs, the equipment will be decontaminated in a manner


21

that removes adhered soils and residues. Soils/residues generated from the

decontamination procedures will be disposed of with the impacted fill/soil mixtures at

the approved off-site disposal facilities. If water is generated during the

decontamination effort, it will either be transferred into 55 gallon drums or directly to

the on-site groundwater treatment system (if used), and/or if in small volume, be

incorporated into the impacted fill/soil mixtures for disposal at the approved off-site

disposal facilities. Any wastes (soils or water) created at the Site will either be sampled

first, or assumed to be impacted, and then disposed of accordingly.

Trucks entering and exiting the Site will be subject to the requirements of the Site

specific erosion and sediment control measures outlined in this RWP and site specific

Stormwater Pollution Prevention Plan (SWPPP), which shall include the requirements

of a stabilized construction entrance to mitigate fill/soil from being tracked off-site and

onto roadways (see Section 2.7). The public roadway(s) where trucks exit the Site will

be monitored by the Remediation Engineer’s field representative. If fill/soil tracking is

apparent, improvements to the erosion and sediment controls and fill/soil loading

procedures will be required and implemented. Trucks entering and exiting the Site will

also conform to the Site’s State Pollutant Discharge Elimination System (SPDES)

General Permit for Stormwater Discharges from Construction Activity.

2.4 Groundwater Dewatering System During Construction

The remedial action and subsequent redevelopment construction activity may require

groundwater dewatering and treatment. DEC will be provided with the dewatering

and treatment system design prior to its implementation. Design of the treatment

system will be the responsibility of the remediation contractor or the vendor

(subcontractor) that specializes in this type of treatment.

It is the Volunteer’s intention to treat groundwater and discharge it to the closest

connection to the municipality’s sanitary collection system (i.e. sanitary lines along

Warburton Avenue, Irving Place and/or Wood Place) with approval from the

municipal authority. If this is implemented, pre- and post-treatment sampling will be

performed of the water treatment system to confirm that the discharge meets the limits

established by the Westchester County DEF. The sampling will be conducted prior to

system startup and during on-going system discharges at sampling frequencies

required by the Westchester County DEF.


22

For the purpose of tracking the volume of treated groundwater that is discharged to the

sanitary collection system, a water meter with a totalizer will be installed in line with

the groundwater treatment system. The groundwater treatment system will be

equipped with equipment to reduce suspended sediment, pre-and post-treatment

sampling ports, and treatment media such as granular activated carbon. It is estimated

that approximately 210,000 gallons of groundwater (predominantly from the 178

Warburton Avenue parcel) will be treated and discharged to the sanitary collection

system.

In lieu of on-site groundwater treatment, the groundwater may be transferred from the

temporary holding tanks and later transported off-site for disposal at an approved and

permitted TSDF facility.

The NYSDEC and the New York State Department of Health (NYSDOH) will be

notified of how the groundwater will be handled and disposed of prior to the remedial

actions occurring on Site.

2.5 Impacted Soil Handling

Fill/soil within the Site boundaries commencing at the ground surface and extending

vertically downwards to approximately two (2) to 12 feet bgs will be considered as

contaminated and will require special handling. The approximate vertical depths of fill

material mantling the Site at each of the sampling locations completed during the RI

and previous investigations are summarized on Figure 2.

The vertical depth of petroleum impacted soils beneath the 178 Warburton Avenue

portion of the Site is estimated from the ground surface to 12 feet bgs (deeper

excavation might be warranted in certain areas). The vertical depth of soil/fill mixtures

mantling remaining portions of the Site is estimated to range from the ground surface to

four (4) to eight (8) feet bgs. Based on these assumptions, it is estimated that

approximately 5,000 cubic yards (9,400 tons) of petroleum impacted soils and 16,500

cubic yards (27,800 tons) of soil/fill mixtures will require remediation. The total

tonnage may vary depending on the material density and changes in excavation depths.

The overall excavation depths may be adjusted based on organic vapor screening with a

PID and visual observations by the Remediation Engineer’s field representative.


23

Confirmatory end-point soil samples will be collected by the Remediation Engineer’s

field representative and analyzed in the laboratory to confirm that the soil that remains

in-place meets applicable SCGs.

Should boulders be encountered during excavation activities, they will be segregated

and stockpiled on-site and assessed by the Remediation Engineer’s field representative

to determine whether the boulders exhibit field evidence of contamination (odors,

sheen, and/or discoloration). Boulders exhibiting field evidence of contamination

(FEC) will not be reused on-site. Boulders with no FEC could be reused on-site,

following a determination by the project’s design engineers that the reuse of this

material is acceptable. Boulders to be reused as backfill will need to be free from

excessive soil/fill prior to processing in order to prevent cross contamination.

Upon completion of the remedial action, excavation of additional native soil may be

necessary to facilitate construction of deeper building foundations. If the confirmatory

endpoint floor samples from the remedial excavation indicate that the native soils are

not impacted above SCGs, these soils will be considered as clean soil and the reuse

and/or disposition of these soils will no longer be regulated per the BCP. Approval to

remove these soils from the Site will require approval from NYSDEC.

The handling of the contaminated fill/soil will involve direct loading into dump trucks

or trailers, and if not directly loaded, temporarily stockpiled on-Site. For soil

stockpiling, the fill/soil will be staged on a minimum of 12-mil plastic and covered with

the same to mitigate washout by rainwater. For directly loaded fill/soil, the

truck/tractor trailers will be covered during transport with solid covers (not mesh), and

if high in moisture content where free-standing water will be released, the truck gates

will be sealed and/or lined with plastic. Mesh tarps or covers will not be allowed for

trucks hauling impacted fill/soil from the Site.

In order to dispose of the contaminated fill/soil at an off-site disposal facility (and to be

able to directly load the material into dump trucks and/or trailers), waste

characterization samples will be collected before the remedial action begins. This will

be accomplished by advancing exploratory test pits and/or soil borings for collection of

representative fill/soil samples for laboratory analysis. The number of samples and

analytical requirements will be in accordance with the target disposal facility(ies)

permit requirements, and if unspecified, shall be at a minimum for the full Toxicity


24

Characteristic Leaching Procedure (TCLP) parameters and RCRA characteristics.

Multiple disposal facilities are anticipated to be use by the Contractor.

It should be noted that the COCs identified as part of the RI are intended to provide a

general description of the contamination at the Site. The concentration ranges of COCs

identified at the sampling locations may be representative of COCs throughout the

Site’s media. Furthermore, both different types and different concentration ranges of

COCs may be encountered during characterization of the Site’s media for disposal

facility purposes.

Disposal facility approval letters and other related documentation will be submitted to

the Remediation Engineer and the DEC Project Manager for review and approval prior

to the exportation of contaminated fill/soil.

All IDW from the RI will be characterized and disposed of off-site.

2.6 Utility Disconnects

The Site is serviced with electricity and natural gas from Con Edison. Potable water is

provided by the City of Yonkers Water Bureau. The Westchester County DEF is

responsible for sanitary sewer service to the Site. Additionally, several private utilities

installed as part of the construction of the Cottage Place Gardens complex are present

beneath the Site. These include steam lines, drainage and storm water piping, and fiber

optic and cable lines. If not already addressed prior to the demolition of the Site

buildings, the Contractor is responsible to locate all utilities and disconnect/terminate

them per State, City, County, Cottage Place Gardens and Municipal Housing Authority

for the City of Yonkers (MHACY) requirements, or properly reroute or protect them

during excavation in cooperation with applicable utility providers.

2.7 Construction Entrance

A stabilized construction entrance(s) will be installed in accordance with a Site-specific

SWPPP to mitigate the tracking of potentially contaminated fill/soil onto public rights-

of-way from vehicle traffic exiting the Site.


25

2.8 Excavation Shoring/Sheeting

The anticipated horizontal and vertical remedial excavation depths may require

sheeting/shoring to effectuate stable and safe excavation conditions. The need for and

design of the sheeting/shoring systems will be the responsibility of the Contractor, and

shall be designed by a NYS licensed professional engineer. Prior to commencement of

the remedial action, excavation sheeting/shoring plans will be submitted to DEC for

their information. Excavation sheeting/shoring plans for non-remedial needs are not

required to be submitted to DEC.


26

3.0 SITE CONTROLS DURING REMEDIAL ACTION

3.1 Stormwater Management

The cumulative area of fill/soil disturbance for this project is greater than one (1) acre

requiring 178 Warburton Limited Partnership to obtain coverage under the State

Pollutant Discharge Elimination System (SPDES) General Permit for Stormwater

Discharges from Construction Activity before commencing construction activity.

In accordance with the New York Guidelines for Urban Erosion and Sediment Control

and the New York State Stormwater Management Design Manual, erosion and

sediment control measures, pollution prevention measures, and if applicable, post-

construction water quality treatment, shall be designed by 178 Warburton Limited

Partnership and presented in the form of a Stormwater Pollution Prevention Plan

(SWPPP).

The following forms are needed to be completed and submitted to comply with the

requirements of the General Permit for Stormwater Discharges from Construction

Activity - GP-0-15-002:

• Notice of Intent (NOI) to DEC, which is a request for coverage under the General

Construction Stormwater Permit;

• SWPPP Acceptance Form, which is required along with the NOI because the Site

is located within the boundaries of an MS4. The SWPPP must be reviewed and

accepted by the MS4 prior to submitting the NOI to the DEC; and

• Notice of Termination (NOT) to DEC, which is a notification that the construction project is complete and has met the requirements of the construction permit.

A copy of the blank Notice of Intent, Notice of Termination and SWPPP Acceptance

forms are available through DEC’s website. The SWPPP, NOI and SWPPP Acceptance

forms will be provided to DEC under separate cover after approval from the City of

Yonkers Engineering Department, but prior to the start of construction. The NOT will

be provided to DEC upon completion of the Site disturbance portion of the project.

Periodic SWPPP inspection reports will be provided to C.T. Male for review and

inclusion in the FER.


27

3.2 Air Monitoring

A Community Air Monitoring Plan (CAMP) will be followed during ground intrusive

remedial activities (i.e., excavation, disturbance and handling of site fill/soil). The

intent of the CAMP is to provide a measure of protection for the downwind community

(i.e., off-site receptors including residences and businesses and on-site workers not

directly involved with the subject work activities) from potential airborne contaminant

releases as a direct result of remedial work activities. The CAMP is not intended for use

in establishing action levels for worker respiratory protection. The CAMP will monitor

the air for dust (particulate air monitoring, see Section 3.2.1) and volatile organic

compound vapors (VOC air monitoring, see Section 3.2.2) at the downwind perimeter

of the work area and/or at occupied buildings within 20 feet of the work area. The

action levels specified herein require increased monitoring, corrective actions to abate

emissions, and/or work shutdown.

Remedial actions will not take place within occupied Site buildings. In areas where

remedial actions will take place within 20 feet of occupied buildings, VOC and

particulate monitoring will be conducted in accordance with the Special Requirements

CAMP. The CAMP and Special Requirements CAMP are included in Appendix D.

3.2.1 Particulate Air Monitoring

Three (3) real-time particulate monitors capable of continuously measuring

concentrations of particulate matter less than 10 micrometers in size (PM-10) and

capable of integrating over a period of 15 minutes (or less) will be utilized. The

instruments will be placed inside environmental enclosures at temporary monitoring

stations based on the prevailing wind direction each work day, one (1) upwind and two

(2) downwind of the designated work areas. If the remedial action is taking place

within 20 feet of occupied structures, monitoring will be conducted opposite the walls

of the occupied structures or next to the structures’ air intake vents.

Each particulate monitor will be equipped with a telemetry unit capable of transmitting

real-time particulate data to the Remediation Engineer and/or the Remediation

Engineer’s field representative. The particulate monitoring instruments will be capable

of displaying and transmitting the short term exposure limit (STEL) or 15 minute

averaging period, which will be compared to the NYSDOH Generic and Special


28

Requirements Community Air Monitoring Plan action levels for particulates, as listed

below. Instrument alarms will be transmitted in real time to the Remediation Engineer

and/or the Remediation Engineer’s field representative via email and/or text message.

The dust monitoring data for the remedial action will be stored in the Environet

database and will be periodically downloaded and stored in C.T. Male’s electronic

project directory.

• If the downwind and/or occupied structures PM-10 particulate level is 100

micrograms per cubic meter (mcg/m3) greater than background (upwind

perimeter) for the 15-minute period or if airborne dust is observed leaving the

work area, then dust suppression techniques must be employed. Work may

continue with dust suppression techniques provided that the downwind and/or

occupied structures PM-10 particulate levels do not exceed 150 mcg/m3 above

the upwind level and provided that no visible dust is migrating from the work

area.

• If, after implementation of dust suppression techniques, the downwind and/or

occupied structures PM-10 particulate levels are greater than 150 mcg/m3 above

the upwind level, work must be stopped and a re-evaluation of activities

initiated. Work can resume provided that dust suppression measures and other

controls are successful in reducing the downwind and/or occupied structures

PM-10 particulate concentration to within 150 mcg/m3 of the upwind level and

in preventing visible dust migration.

In the event of poor weather such as heavy rain, particulate monitoring will not be

performed for protection of instrumentation. These weather conditions would limit the

effectiveness of the sensitive monitoring equipment and likely suppress particulate

generation. Work activities will be halted if fugitive dust migration is visually observed

for a sustained period of time during poor weather conditions.

3.2.2 Volatile Organic Compound Air Monitoring

C.T. Male will continuously monitor for VOCs at the downwind perimeter of the

immediate work areas and/or occupied structures with a MiniRAE 3000 VOC monitor

or equal. The VOC monitors will be placed in the downwind and occupied structures

environmental enclosures containing a particulate monitor. The downwind VOC

monitors will be equipped with telemetry units capable of transmitting real-time VOC


29

data to the Remediation Engineer and/or the Remediation Engineer’s field

representative. The VOC monitoring instruments will be capable of displaying and

transmitting the short term exposure limit (STEL) or 15 minute averaging period, which

will be compared to the NYSDOH Generic and Special Requirements Community Air

Monitoring Plan action levels for VOCs, as listed below. Instrument alarms will be

transmitted in real time to the Remediation Engineer and/or the Remediation

Engineer’s field representative via email and/or text message. The VOC monitoring

data for the remedial action will be stored in the Environet database and will be

periodically downloaded and stored in C.T. Male’s electronic project directory.

Upwind VOC STEL concentrations will be measured at the start of the work day and

periodically thereafter employing a handheld MiniRae 3000 VOC monitor to evaluate

the Site’s background conditions. The upwind VOC STEL readings will be manually

recorded for future reference and reporting.

• If the ambient air concentration of total organic vapors opposite the walls of

occupied structures exceeds 1 ppm above background for the 15-minute average,

work activities will be temporarily halted and monitoring will be conducted

within the occupied structure.

• If the ambient air concentration of total organic vapors at the downwind

perimeter of the work area or exclusion zone (not including the occupied

structures) exceeds 5 parts per million (ppm) above background for the 15-

minute average, work activities will be temporarily halted and monitoring

continued. If the total organic vapor level readily decreases (per instantaneous

readings) below 5 ppm over background, work activities can resume with

continued monitoring.

• If total organic vapor levels at the downwind perimeter of the work area or

exclusion zone (not including the occupied structures) persist at levels in excess

of 5 ppm over background but less than 25 ppm, work activities will be halted,

the source of vapors identified, corrective actions taken to abate emissions, and

monitoring continued. After these steps, work activities can resume provided

that the total organic vapor level 200 feet downwind of the exclusion zone or half

the distance to the nearest potential receptor or residential/commercial structure,


30

whichever is less - but in no case less than 20 feet, is below 5 ppm over

background for the 15-minute average.

• If the organic vapor level is above 25 ppm at the perimeter of the work area,

activities will be shutdown. Work activities will then be evaluated to determine

the source of the organic vapors and the engineering controls required to

reduce/eliminate the organic vapors.

3.3 Noise and Vibration

There is potential for noise and vibration to be an issue depending on the means and

methods selected by the construction contractor to excavate and load the Site fill/soil

during the remedial action. If sheet piling is used to facilitate the excavation of Site

fill/soil during the remedial excavation, the project plans and specifications will require

the contractor to plan for and provide as necessary, controls to monitor and mitigate

noise and vibration from adversely affecting nearby buildings, structures,

improvements and the community.

3.4 Dust Control

Dust suppression techniques will be required, as necessary, to control fugitive dust to

the extent practical during the remedial action. Such techniques must be employed, at a

minimum, if the community air monitoring results indicate that particulate levels are

above action levels. All reasonable attempts will be made to inhibit visible and/or

fugitive dusts. Techniques to be utilized by the contractor may include one or more of

the following:

• Applying water to haul roads.

• Wetting equipment and excavation faces.

• Spraying water on buckets during excavation and dumping.

• Hauling materials in containers or vehicles with solid tarp covers.

• Restricting vehicle speeds on-site.

• Covering excavated areas and materials after excavation immediately after

activity ceases.


31

The contractor will be required to perform dust control measure in a manner consistent

with the applicable portions of the “New York Guidelines for Urban Erosion and

Sediment Control” and the “New York State Stormwater Management Design Manual”.

3.5 Construction Observation and Certification

Phase I (preparation for the remedial action) work includes asbestos abatement

followed by demolition of the Site buildings. A licensed asbestos project monitor will

be retained during the ACM abatement work, as required by ICR-56. The asbestos

project monitor will be responsible for collecting daily air samples in accordance with

ICR-56. As air monitoring will be conducted per DOL requirements during the ACM

abatement work, CAMP related air monitoring will not be performed during this

portion of the work. Once the ACM has been abated, C.T. Male will provide a full-time

construction observer to monitor the building demolition aspect of the project and

conduct CAMP monitoring.

Phase II (remedial action) work includes closure by removal of USTs, hydraulic lifts and

drainage systems; excavation (disturbance) of existing fill/soil; possible groundwater

evacuation, characterization, treatment and disposal; abandonment of monitoring wells;

and possible installation of sheeting and shoring within the remedial excavation. C.T.

Male will provide full-time observation during the remedial action. At the point in

construction when the environmental related issues have been fully addressed (i.e.,

USTs, hydraulic lifts and drainage systems closed; impacted fill/soil removed and off-

site; groundwater treatment is stabilized or completed; and CAMP monitoring is no

longer required, etc.), construction observation by C.T. Male will cease, unless some

other unforeseen condition is identified necessitating further observation..

Periodic observation during the remedial action will be conducted by a C.T. Male

Remediation Engineer in order to provide the required certification of the FER. The

Remediation Engineer will supervise the construction observer (field representative)

during the remedial action to document that the project is implemented in accordance

with the DEC approved RWP. The Remediation Engineer will provide engineering

review of remedial related contractor submittals and field changes for the remedial

related work.


32

3.6 Odor Control

If nuisance odors are identified to extend beyond the perimeter of the work area during

remedial action ground intrusive activities, measures that may be implemented to abate

the nuisance odors include limiting the area of open excavations, limiting the size of soil

stockpiles, shrouding open excavations with tarps and other covers, direct load-out of

soils to trucks for off-site disposal, use of chemical odorants via spray or misting

systems, and use of staff to monitor odors in surrounding neighborhoods.


33

4.0 HEALTH AND SAFETY PLAN (HASP)

Health and safety procedures to be followed by C.T. Male will be conducted in

accordance with a site-specific Health and Safety Plan (HASP), which is included in

Appendix E. The HASP will be available at the Site during the remedial action.

The contractor completing the remedial work will be required to provide a site specific

HASP that is certified by a Certified Industrial Hygienist, Certified Safety Professional

or Remediation Engineer determined equivalent safety professional. The contractor’s

employees will be required to have read and understood their company’s site specific

HASP prior to completing the work.


34

5.0 CONFIRMATION AND DOCUMENTATION SAMPLING

5.1 Tank Closure Sampling

There are currently two (2) known USTs located to the east of Building 12 (see Figure 2)

and the potential for additional tanks in and around the 178 Warburton Avenue portion

of the Site. Upon removal of the tanks (following emptying and cleaning procedures),

C.T. Male’s field representative will assess the soils surrounding the tanks for organic

vapors employing PID headspace analyses and organoleptic perception.

If the soils do not appear impacted and the bottoms of the tanks are in native soil, post-

remediation confirmation samples will be collected per Section 5.3. If the soils do not

appear impacted and the bottoms of the tanks are in fill material, the fill material will be

excavated to native soils and post-remediation confirmation samples will be collected

per Section 5.3. The samples will be analyzed for the Target Compound List (TCL) of

VOCs, SVOCs, pesticides and polychlorinated biphenyls (PCB), the Target Analyte List

(TAL) of metals (including mercury), hexavalent chromium and cyanide (TCL/TAL

Parameters).

If the soils appear impacted, additional excavation will be conducted until the soils no

longer appear impacted employing the above field screening methods. Floor and

sidewall samples will be collected from the tank excavation for analyses for the

TCL/TAL Parameters to document that the impacted soils have been sufficiently

remediated. The impacted soils will be staged atop poly and covered pending waste

characterization and off-site disposal.

5.2 Hydraulic Lifts and Drainage Systems Closure Sampling

Hydraulic lifts and drainage systems are located in and around the concrete slab of the

former building within the 178 Warburton Avenue portion of the Site (see Figure 2).

Upon removal of the hydraulic lifts and drainage systems, the Remediation Engineer’s

field representative will assess the soils surrounding the hydraulic lifts and drainage

systems for organic vapors employing PID headspace analyses and organoleptic

perception.


35

If the soils do not appear impacted and the bottoms of the hydraulic lifts/drainage

structures are in native soil, post-remediation confirmation samples will be collected

per Section 5.3. If the soils do not appear impacted and the bottoms of the hydraulic

lifts/drainage structures are in fill material, the fill material will be excavated to native

soils and post-remediation confirmation samples will be collected per Section 5.3. The

samples will be analyzed for the TCL/TAL Parameters.

If the soils surrounding any of the hydraulic lifts and/or drainage systems appear

impacted, additional excavation will be conducted until the soils no longer appear

impacted employing the above field screening methods. Floor and sidewall samples

will be collected from the excavation(s) for analyses for the TCL/TAL Parameters to

document that the impacted soils have been sufficiently remediated. The impacted soils

will be staged atop poly and covered pending waste characterization and off-site

disposal.

5.3 Post-Excavation Confirmation Sampling

Post-excavation confirmation soil samples will be collected for laboratory analysis after

removal of impacted fill/soil to document that SCGs have been met. The samples will

be analyzed for the TCL/TAL Parameters (including emerging contaminant [EC] 1,4-

dioxane). A subset of the samples will be analyzed for the NYSDEC list of 21 per- and

polyfluorinated alkyl substances (PFAS) as per the NYSDEC-approved Sampling Plan

for ECs (dated February 7, 2020). The Sampling Plan for ECs is presented in Appendix

F. If a certain parameter does not meet the project SCGs, that area will be further

excavated and resampled. These samples will be analyzed for only those parameters

that had exceedances in the initial samples.

Post-excavation verification soil samples will be collected at a frequency of one (1) grab

sample per each 900 square feet of excavation floor and one (1) sample from the bottom

of the eastern and western sidewalls for every 30 linear feet of sidewall, pursuant to

DEC DER-10. Sidewall samples will not be collected from the northern and southern

sidewalls as these sidewalls extend into the CPG Phase 3A and Phase 4 BCP Sites (BCP

Site No.’s C360150 and C360160, respectively). Impacted soil/fill mixtures have been

effectively remediated at the CPG Phase 3A and Phase 4 BCP Sites and the Sites have

been backfilled with imported fill meeting SCOs for Unrestricted Use Sites. In the event

that the excavations do not extend to the sidewalls of the CPG Phase 3A and Phase 4


36

BCP sites, confirmatory sidewall samples will be required. Any proposed modifications

to sampling type and frequency will be submitted to the DEC Project Manager for

review and approval.

5.4 Quality Assurance/Quality Control and Deliverables

Quality Assurance/Quality Control (QA/QC) samples at a ratio of (one) 1 set of

QA/QC samples per 20 media samples will be collected and analyzed. The QA/QC

samples for soils will include a blind field duplicate (FD) and matrix spike (MS)/matrix

spike duplicate (MSD).

The laboratory will provide the analytical results in DEC ASP Category B Data

Deliverable format for subsequent third party data validation. Data validation will be

performed in accordance with the USEPA National and Regional Validation

Guidelines/Procedures to determine the applicable qualifications of the data. The

validator will then prepare a Data Usability Summary Report (DUSR) for all post-

excavation confirmatory samples in accordance with DEC guidance. All of the

laboratory data will also be submitted electronically to NYSDEC in Version 4 EQuIS

database format.

5.5 Groundwater Treatment Documentation Sampling

Groundwater treatment may be necessary during the remedial action and subsequent

new sub-grade construction. Groundwater treatment shall be implemented when there

is a petroleum sheen on the water surface, the groundwater comes into contact with

petroleum contaminated soil, and/or testing for approval to discharge groundwater to

the municipal storm/sewer system shows contaminants above applicable acceptance

parameters. Groundwater that does not appear impacted will be managed on-Site.

Approval will be obtained from the Remediation Engineer and the DEC Project

Manager prior to managing groundwater on-Site.

The documentation and sampling necessary for the groundwater treatment system will

be dependent on the requirement of the applicable Westchester County DEF permit for

such treatment system. Documentation will likely include influent (prior to treatment)

and effluent (post treatment) sampling which will be used to gauge groundwater

contaminant levels, document conformance to applicable permit discharge limits, and


37

set forth the frequency of change-out of groundwater treatment media. The proposed

sampling frequency and analysis will be presented to DEC for concurrence prior to its

implementation. If it is determined that groundwater is to be discharged to the

municipal system under a permit, the sample results will be provided to the DEC

Project Manager prior to discharge.

In lieu of a groundwater treatment system, groundwater staged in temporary holding

tanks may be removed and transported for off-site disposal at a permitted TSDF facility.

5.6 Imported Fill Testing

The source of the fill and the analytical data will be provided to the DEC Project

Manager for review and approval prior to importing the fill to the Site. The sampling

and analysis requirements for fill imported to the Site are set forth in 5.4(e)10 of DEC

DER-10. The following requirements must also be met:

• All materials proposed for import onto the Site will be approved by the

certifying Remediation Engineer and the DEC Project Manager, and will be in

compliance with provisions in 6 NYCRR Part 375 and DER-10 prior to delivery to

the Site.

• Material from industrial sites, spill sites, or other environmental remediation

sites or potentially contaminated sites will not be imported to the Site.

• All imported soils will meet the backfill quality standards established in 6

NYCRR 375-6.7(d). Based on an evaluation of the land use, protection of

groundwater and protection of ecological resources criteria, the resulting soil

quality standards are listed in Table 375-6.8(a) in Appendix B.

DEC may require that select samples of imported fill be analyzed for the

emerging contaminants (ECs) 1,4-dioxane and the DEC list of 21 per- and

polyfluoroalkyl substances (PFAS). The EC analytical results will be reviewed by

the DEC Project Manager to determine if the fill material is suitable for import

onto the Site.


38

Soils that meet ‘exempt’ fill requirements under 6 NYCRR Part 360, but do not

meet backfill objectives for this Site, will not be imported onto the Site without

prior approval by DEC. Solid waste will not be imported onto the Site.

• Trucks entering the Site with imported soils will be securely covered with tight

fitting solid covers. Imported soils will be stockpiled separately from excavated

materials and covered to prevent dust releases.


39

6.0 APPLICABLE PERMITS AND RELATED

6.1 ACM Abatement/Building Demolition Work

Prior to starting asbestos abatement, there are two (2) required notifications, one (1) on

the State level and one (1) on the Federal level (USEPA). There is a minimum 10

calendar day pre-notification of the ACM abatement activity from the NYSDOL (State),

which will be sought by the asbestos abatement contractor. There is a 19 working day

pre-notification of demolition and renovation from USEPA, which will be solicited by

the asbestos abatement contractor. Each building shall be considered a separate project

for the NYSDOL pre-notification requirements.

A Building Permit will be sought from the City of Yonkers by the Owner (or the

contractor, as applicable) prior to the initiation of the demolition activities and

construction activities.

A City of Yonkers Demolition Permit shall be prepared by and secured by the General

Contractor. As part of the application, the applicant is required to engage a licensed

firm to inspect the structure for the presence of asbestos, which will be performed by

C.T. Male. A copy of C.T. Male’s Asbestos Survey will be made available to the General

Contractor. The applicant shall file a certificate of finding with the City of Yonkers

Department of Housing and Buildings (DHB) prior to the issuance of a Demolition

permit. The asbestos removal project cannot be started unless and until satisfactory

proof of compliance with Article 30 of Labor Law of the State of New York is filed with

the City of Yonkers DHB and a permit has been obtained from the City of Yonkers DHB

for any asbestos removal.

Copies of, or evidence of the DOL notification, the approved building permit, and the

approved demolition permit will be made part of the Final Engineering Report.

6.2 Soil Remediation and UST Closures

The remediation contractor will be responsible for obtaining applicable permits from

the City of Yonkers DHB prior to the commencement of soil remediation and/or tank

closures.


40

6.3 Groundwater Discharge

A dewatering system may be necessary during the remedial action and subsequent new

subgrade construction to mitigate groundwater infiltration. Groundwater extracted

from the subsurface may require treatment (see Section 5.5) prior to discharge to the

closest MS4 combined sewer manhole, which will require a sewer discharge permit.

The requirements of a sewer discharge permit will be sought from the Westchester

County DEF; the entity that operates the local sewage treatment plant. DEC will be

provided a copy of the approval to discharge to the sewer, when applied for and

received from DEF. It will be the remediation contractor’s responsibility to obtain the

necessary permit(s).

If the volume of groundwater requiring treatment is anticipated to be low, the impacted

groundwater may be pumped to temporary tank(s) and periodically removed from the

Site in tanker trucks. The tank liquids will be properly managed and disposed of off-

site at an approved and permitted TSDF. The wastes will be transported by a 6 NYCRR

Part 364 transporter permitted to transport these types of wastes, and disposed of at a

facility permitted to accept the waste being disposed of.


41

7.0 SITE RESTORATION

7.1 General

The Site will be restored upon completion of work in accordance with the plans and

specifications for new construction. Imported backfill will be tested in accordance with

Section 5.6. Once the Site is backfilled to final grade or at some point prior to when

existing Site soils have been fully remediated, CAMP monitoring will be discontinued

with pre-approval from DEC and the NYSDOH.


42

8.0 REPORTING AND CERTIFICATE OF COMPLETION

8.1 Weekly Progress Updates

Progress meeting minutes will be submitted to the DEC Project Manager via email

during the remedial action (Phase II only). The progress report will briefly summarize

the remedial activities completed at the Site for the previous week. The progress report

will be submitted at the beginning of the following week. The format will be in a

bulleted style generally highlighting the major items accomplished during the previous

week. Results of the CAMP will also be included in the weekly progress reports.

Additionally, if there are any exceedances during the CAMP monitoring, NYSDEC and

NYSDOH will be notified immediately (including the reason for the exceedance,

corrective actions taken, and whether these were effective) via email and not solely in

the weekly report.

8.2 Monthly Progress Reports

Monthly progress reports will report on the progress of the remedial actions

accomplished during the reporting period. The reports will be submitted to DEC, with

GENERIC AND SPECIAL REQUIREMENTS CAMP

Final DER-10 Page 204 of 226 Technical Guidance for Site Investigation and Remediation May 2010

Appendix 1A New York State Department of Health

Generic Community Air Monitoring Plan

Overview

A Community Air Monitoring Plan (CAMP) requires real-time monitoring for volatile organic compounds (VOCs) and particulates (i.e., dust) at the downwind perimeter of each designated work area when certain activities are in progress at contaminated sites. The CAMP is not intended for use in establishing action levels for worker respiratory protection. Rather, its intent is to provide a measure of protection for the downwind community (i.e., off-site receptors including residences and businesses and on-site workers not directly involved with the subject work activities) from potential airborne contaminant releases as a direct result of investigative and remedial work activities. The action levels specified herein require increased monitoring, corrective actions to abate emissions, and/or work shutdown. Additionally, the CAMP helps to confirm that work activities did not spread contamination off-site through the air.

The generic CAMP presented below will be sufficient to cover many, if not most, sites. Specific requirements should be reviewed for each situation in consultation with NYSDOH to ensure proper applicability. In some cases, a separate site-specific CAMP or supplement may be required. Depending upon the nature of contamination, chemical- specific monitoring with appropriately-sensitive methods may be required. Depending upon the proximity of potentially exposed individuals, more stringent monitoring or response levels than those presented below may be required. Special requirements will be necessary for work within 20 feet of potentially exposed individuals or structures and for indoor work with co-located residences or facilities. These requirements should be determined in consultation with NYSDOH.

Reliance on the CAMP should not preclude simple, common-sense measures to keep VOCs, dust, and odors at a minimum around the work areas.

Community Air Monitoring Plan

Depending upon the nature of known or potential contaminants at each site, real-time air monitoring for VOCs and/or particulate levels at the perimeter of the exclusion zone or work area will be necessary. Most sites will involve VOC and particulate monitoring; sites known to be contaminated with heavy metals alone may only require particulate monitoring. If radiological contamination is a concern, additional monitoring requirements may be necessary per consultation with appropriate DEC/NYSDOH staff.

Continuous monitoring will be required for all ground intrusive activities and during the demolition of contaminated or potentially contaminated structures. Ground intrusive activities include, but are not limited to, soil/waste excavation and handling, test pitting or trenching, and the installation of soil borings or monitoring wells.

Periodic monitoring for VOCs will be required during non-intrusive activities such as the collection of soil and sediment samples or the collection of groundwater samples from existing monitoring wells. APeriodic@ monitoring during sample collection might reasonably consist of taking a reading upon arrival at a sample location, monitoring while opening a well cap or


overturning soil, monitoring during well baling/purging, and taking a reading prior to leaving a sample location. In some instances, depending upon the proximity of potentially exposed individuals, continuous monitoring may be required during sampling activities. Examples of such situations include groundwater sampling at wells on the curb of a busy urban street, in the midst of a public park, or adjacent to a school or residence.

VOC Monitoring, Response Levels, and Actions

Volatile organic compounds (VOCs) must be monitored at the downwind perimeter of the immediate work area (i.e., the exclusion zone) on a continuous basis or as otherwise specified. Upwind concentrations should be measured at the start of each workday and periodically thereafter to establish background conditions, particularly if wind direction changes. The monitoring work should be performed using equipment appropriate to measure the types of contaminants known or suspected to be present. The equipment should be calibrated at least daily for the contaminant(s) of concern or for an appropriate surrogate. The equipment should be capable of calculating 15-minute running average concentrations, which will be compared to the levels specified below.

1. If the ambient air concentration of total organic vapors at the downwind perimeter of the work area or exclusion zone exceeds 5 parts per million (ppm) above background for the 15-minute average, work activities must be temporarily halted and monitoring continued. If the total organic vapor level readily decreases (per instantaneous readings) below 5 ppm over background, work activities can resume with continued monitoring.

2. If total organic vapor levels at the downwind perimeter of the work area or exclusion zone persist at levels in excess of 5 ppm over background but less than 25 ppm, work activities must be halted, the source of vapors identified, corrective actions taken to abate emissions, and monitoring continued. After these steps, work activities can resume provided that the total organic vapor level 200 feet downwind of the exclusion zone or half the distance to the nearest potential receptor or residential/commercial structure, whichever is less - but in no case less than 20 feet, is below 5 ppm over background for the 15-minute average.

3. If the organic vapor level is above 25 ppm at the perimeter of the work area, activities must be shutdown.

4. All 15-minute readings must be recorded and be available for State (DEC and NYSDOH) personnel to review. Instantaneous readings, if any, used for decision purposes should also be recorded.

Particulate Monitoring, Response Levels, and Actions

Particulate concentrations should be monitored continuously at the upwind and downwind perimeters of the exclusion zone at temporary particulate monitoring stations. The particulate monitoring should be performed using real-time monitoring equipment capable of measuring particulate matter less than 10 micrometers in size (PM-10) and capable of integrating over a period of 15 minutes (or less) for comparison to the airborne particulate action level. The equipment must be equipped with an audible alarm to indicate exceedance of the action level. In addition, fugitive dust migration should be visually assessed during all work activities.


1. If the downwind PM-10 particulate level is 100 micrograms per cubic meter (mcg/m3) greater than background (upwind perimeter) for the 15-minute period or if airborne dust is observed leaving the work area, then dust suppression techniques must be employed. Work may continue with dust suppression techniques provided that downwind PM-10 particulate levels do not exceed 150 mcg/m3

above the upwind level and provided that no visible dust is migrating from the work area.

2. If, after implementation of dust suppression techniques, downwind PM-10 particulate levels are greater than 150 mcg/m3 above the upwind level, work must be stopped and a re-evaluation of activities initiated. Work can resume provided that dust suppression measures and other controls are successful in reducing the downwind PM-10 particulate concentration to within 150 mcg/m3 of the upwind level and in preventing visible dust migration.

3. All readings must be recorded and be available for State (DEC and NYSDOH) and County Health personnel to review.

December 2009

SPECIAL REQUIREMENTS COMMUNITY AIR MONITORING PROGRAM

Special Requirements for Work within 20 feet of Potentially Exposed Individuals or Structures

When work areas are within 20 feet of potentially exposed populations or occupied structures, the continuous monitoring locations for VOCs and particulates must reflect the nearest potentially exposed individuals and the location of ventilation system intakes for nearby structures. The use of engineering controls such as vapor/dust barriers, temporary negative-pressure enclosures, or special ventilation devices should be considered to prevent exposures related to the work activities and to control dust and odors. Consideration should be given to implementing the planned activities when potentially exposed populations are likely to be lower, such as during weekends or evening hours in non-residential settings.

• If total VOC concentrations opposite the walls of occupied structures or next to intake vents exceed 1 ppm, monitoring should occur within the occupied structure(s). Background readings in the occupied spaces must be taken prior to commencement of the planned work. Any unusual background readings should be discussed with NYSDOH prior to commencement of the work.

• If total particulate concentrations opposite the walls of occupied structures or next to intake vents exceed 150 mcg/m3, work activities should be suspended until controls are implemented and are successful in reducing the total particulate concentration to 150 mcg/m3 or less at the monitoring point.

• Depending upon the nature of contamination and remedial activities, other parameters (e.g., explosivity, oxygen, hydrogen sulfide, carbon monoxide) may also need to be monitored. Response levels and actions should be pre-determined, as necessary for each site.

Special Requirements for Indoor Work with Co-Located Residences or Facilities

Unless a self-contained, negative-pressure enclosure with proper emission controls will encompass the work area, all individuals not directly involved with the planned work must be absent from the room in which the work will occur. Monitoring requirements shall be as stated above under “Special Requirements for Work within 20 Feet of Potentially Exposed Individuals or Structures” except that in this instance “nearby/occupied structures” would be adjacent occupied rooms. Additionally, the location of all exhaust vents in the room and their discharge points, as well as potential

vapor pathways (openings, conduits, etc.) relative to adjoining rooms, should be understood and the monitoring locations established accordingly. In these situations, it is strongly recommended that exhaust fans or other engineering controls be used to create negative air pressure within the work area during remedial activities. Additionally, it is strongly recommended that the planned work be implemented during hours (e.g. weekends or evening) when building occupancy is at a minimum.

2.0 HEATLH AND SAFETY PERSONNEL

The Health and Safety Officer (HSO) will be responsible for implementation of the

HASP and the delegation of health and safety duties. The HSO will coordinate the

resolution of safety issues that arise during Site work. When field operations

require Level D protection, it will not be necessary for the HSO to be present on-Site

at all times. When the HSO is not present on-Site, a designee will be authorized to

perform the duties of the HSO. The designee will be responsible for implementation

of the HASP in the absence of the HSO.

The HSO or designee has stop work authorization which the HSO or designee will

execute upon the HSO or designee’s determination of an eminent safety hazard,

emergency situation or other potentially dangerous situations (e.g. weather

conditions), when this action is deemed appropriate. Authorization to resume work

will be issued by the HSO.

3.0 SITE LOCATION AND DESCRIPTION

The Site is approximately 1.47 acres in size and is comprised of the west-central

portion of the overall Cottage Place Gardens (CPG) complex (Tax Map #2.-2094-1)

addressed as 8 Cottage Place and a contiguous parcel along the eastern side of

Warburton Avenue identified as 178 Warburton Avenue (Tax Map #2.-2095-33).

The site is currently improved with three (3) multi-story brick apartment buildings

within the CPG complex. The one (1) single-story concrete block structure located at

178 Warburton Avenue has been demolished; all that remains of this building is its

concrete pad. The three (3) brick apartment buildings are identified as Buildings 4, 8

and 12 within the CPG complex and were constructed in the 1940’s during

development of the CPG complex. The former structure at 178 Warburton Avenue

has historically been utilized as a gasoline station and vehicle repair facility. The

remainder of the Site consists of landscaped areas, and concrete and asphalt

walkways and access-ways.

Two (2) underground tanks are currently located beneath the Site. The tanks are no

longer in use, but historically contained fuel oil for boilers located in Building 12.

The tanks are located beneath asphalt pavement to the east of Building 12. Former

hydraulic lifts and drainage structures are believed to be affiliated with past

automotive repair operations within the western portion of the Site at 178

Warburton Avenue.

There is no water body located on the Site or on immediately adjacent properties.

Land usage surrounding the Site consists of residential and multi-family dwellings,

and mixed commercial development.

The Site is serviced with electricity and natural gas from Con Edison. Public water

and sewer are provided by the City of Yonkers and Westchester County,

respectively.

4.0 POTENTIAL SITE CONTAMINANTS

Based on analytical results from previous Phase II Environmental Site Assessments

(ESAs) and the BCP Remedial Investigation, known and suspected contaminants in

the Site’s media are identified below. Contaminants of concern (COCs) in fill/soil

have exceeded Soil Cleanup Objectives (SCOs) for Unrestricted Use Sites

promulgated at 6 NYCRR Part 375. COCs in groundwater have exceeded NYS

regulatory groundwater standards and guidance values.

The specific COC analytes in fill material mantling the Site include the VOCs

benzene, ethylbenzene, toluene and xylenes; the SVOCs 3-methylphenol/4-

methylphenol, benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene,

benzo(k)fluoranthene, chrysene, dibenzo(a,h)anthracene, fluoranthene and

indeno(1,2,3-cd)pyrene, phenol; the pesticides 4,4-DDD, 4,4-DDE and 4,4-DDT; and

the metals cadmium, chromium, copper, lead, mercury and zinc.

The specific COC analytes in groundwater include the VOCs acetone, benzene,

ethylbenzene, isopropylbenzene, MtBE, toluene and xylenes; the SVOCs

benzo(a)anthracene, benzo(b)fluoranthene, benzo(k)fluoranthene, chrysene,

indeno(1,2,3-cd)pyrene, naphthalene and phenol; and the metals barium, chromium,

copper, iron, lead, manganese, mercury, nickel and sodium.

5.0 HAZARD ASSESSMENT

5.1 General

The hazard assessment, use of specific protective equipment, and monitoring

associated with each field work task of the Pre-Design Investigation and Remedial

Action to be conducted at the Site are presented in following subsections.

For this project, C.T. Male and 178 Warburton Limited Partnership will be

contracting/subcontracting portions of the Pre-Design Investigation and Remedial

Action activities. Each contractor/subcontractor will be responsible for developing

and implementing a health and safety plan for their activities, for protection of their

employees and subcontractors and use of personal protective equipment. The

contractor/subcontractor will also be responsible for developing and following their

own Respiratory Protection Program, as applicable.

5.2 Subsurface Work

Subsurface work will include the advancement of test pits and/or test borings to aid

in the collection of fill/soil samples for disposal facility waste characterization; the

decommissioning of monitoring wells; the excavation and temporary staging

and/or direct load-out of fill/soil for off-site disposal; the closure by removal of

underground tanks, hydraulic lifts and drainage structures; and excavation

groundwater dewatering, treatment and disposal.

The potential hazards to personnel during this work are dermal contact and a low

potential for vapor and dust inhalation of potential Site contaminants. Level D

protection should be sufficient to protect against dermal contact during

advancement of test pits and test borings; decommissioning of monitoring wells;

soil excavation and/or handling of the subsurface fill/soils, and excavation

dewatering. If organic vapors are present at the action levels described in Section

5.3, on the basis of organic vapor monitoring of the area during the work, it may be

necessary to upgrade to Level C respiratory protection.


9

5.3 Air Monitoring

During the completion of the Pre-Design Investigation and Remedial Action, the

ambient air in the work area will be monitored for organic vapors employing a

photoionization detection (PID) meter (MiniRAE 3000) prior to the start of work and

periodically as conditions warrant. If a concentration of 10 parts per million (ppm,

sustained for 5 minutes) of total volatile compounds is detected within the work

area on the instrument, relative to an isobutylene standard (used to calibrate the

instrument), work will cease immediately and the workers shall leave the work area

immediately. The level of personal protective equipment (PPE) protection will be

evaluated prior to continuing work. If a PPE upgrade to Level C is required, it will

include: a half face air purifying respirator equipped with combination organic

vapor and particulate cartridges for 10-15 ppm exposure levels; and a full-face air

purifying respirator for greater than 15 ppm to less than 50 ppm exposure levels,

prior to continuing work. If a concentration greater than 50 ppm is encountered,

work will cease immediately and the situation will be evaluated prior to

continuation of work. Table 1 summarizes the action levels relative to the required

respiratory protection.

Table 1

C.T. Male Action Levels & Required Respiratory Protection

Action Level Level of PPE Type of Respiratory Protection

0-10 parts per million Level D No respiratory protection

10-15 parts per million Level C Half-face air purifying respirator

15-50 parts per million Level C Full-face air purifying respirator

Greater than 50 Cease Work Evaluate work procedures

-Facial hair is not permitted while wearing most respirators.

-Workers required to wear a respirator must have a minimum of OSHA 40 Hour training with current medical monitoring and fit test documentation.

5.4 Community Air Monitoring Plan

A Community Air Monitoring Plan (CAMP) will be followed if ground intrusive

activities having the ability to disturb the Site’s fill/soil are conducted during the

Pre-Design Investigation and Remedial Action. These include the advancement of

test pits and test borings and impacted fill/soil excavation/handling.


10

The intent of the CAMP is to provide a measure of protection for the downwind

community (i.e., off-site receptors including residences and businesses and on-site

workers not directly involved with the subject work activities) from potential

airborne contaminant releases as a direct result of remedial work activities. The

CAMP is not intended for use in establishing action levels for worker respiratory

protection. The CAMP will monitor the air for dust (particulate air monitoring, see

Section 5.4.1) and volatile organic compound vapors (VOC air monitoring, see

Section 5.4.2) at the downwind perimeter of the work area and/or at occupied

buildings within 20 feet of the work area. The action levels specified herein require

increased monitoring, corrective actions to abate emissions, and/or work shutdown.

Remedial actions will not take place within occupied Site buildings. In areas where

remedial actions will take place within 20 feet of occupied buildings, VOC and

particulate monitoring will be conducted in accordance with the Special

Requirements CAMP. The CAMP and Special Requirements CAMP are included in

Appendix B.

5.4.1 Particulate Air Monitoring

Three (3) real-time particulate monitors capable of continuously measuring

concentrations of particulate matter less than 10 micrometers in size (PM-10) and

capable of integrating over a period of 15 minutes (or less) will be utilized. The

instruments will be placed inside environmental enclosures at temporary

monitoring stations based on the prevailing wind direction each work day, one (1)

upwind and two (2) downwind of the designated work areas. If the remedial action

is taking place within 20 feet of occupied structures, monitoring will be conducted

opposite the walls of the occupied structures or next to the structures’ air intake

vents.

Each particulate monitor will be equipped with a telemetry unit capable of

transmitting real-time particulate data to the Remediation Engineer and/or the

Remediation Engineer’s field representative. The particulate monitoring

instruments will be capable of displaying and transmitting the short term exposure

limit (STEL) or 15 minute averaging period, which will be compared to the

NYSDOH Generic and Special Requirements Community Air Monitoring Plan

action levels for particulates, as listed below. Instrument alarms will be transmitted


11

in real time to the Remediation Engineer and/or the Remediation Engineer’s field

representative via email and/or text message. The dust monitoring data for the

remedial action will be stored in the Environet database and will be periodically

downloaded and stored in C.T. Male’s electronic project directory.

• If the downwind and/or occupied structures PM-10 particulate level is 100

micrograms per cubic meter (mcg/m3) greater than background (upwind

perimeter) for the 15-minute period or if airborne dust is observed leaving the

work area, then dust suppression techniques must be employed. Work may

continue with dust suppression techniques provided that the downwind

and/or occupied structures PM-10 particulate levels do not exceed 150

mcg/m3 above the upwind level and provided that no visible dust is

migrating from the work area.

• If, after implementation of dust suppression techniques, the downwind

and/or occupied structures PM-10 particulate levels are greater than 150

mcg/m3 above the upwind level, work must be stopped, and a re-evaluation

of activities initiated. Work can resume provided that dust suppression

measures and other controls are successful in reducing the downwind

and/or occupied structures PM-10 particulate concentration to within 150

mcg/m3 of the upwind level and in preventing visible dust migration.

In the event of poor weather such as heavy rain, particulate monitoring will not be

performed for protection of instrumentation. These weather conditions would limit

the effectiveness of the sensitive monitoring equipment and likely suppress

particulate generation. Work activities will be halted if fugitive dust migration is

visually observed for a sustained period of time during poor weather conditions.

5.4.2 Volatile Organic Compound Air Monitoring

C.T. Male will continuously monitor for VOCs at the downwind perimeter of the

immediate work areas and/or occupied structures with a MiniRAE 3000 VOC

monitor or equal. The VOC monitors will be placed in the downwind and occupied

structures environmental enclosures containing a particulate monitor. The

downwind VOC monitors will be equipped with telemetry units capable of

transmitting real-time VOC data to the Remediation Engineer and/or the

Remediation Engineer’s field representative. The VOC monitoring instruments will


12

be capable of displaying and transmitting the short term exposure limit (STEL) or 15

minute averaging period, which will be compared to the NYSDOH Generic and

Special Requirements Community Air Monitoring Plan action levels for VOCs, as

listed below. Instrument alarms will be transmitted in real time to the Remediation

Engineer and/or the Remediation Engineer’s field representative via email and/or

text message. The VOC monitoring data for the remedial action will be stored in the

Environet database and will be periodically downloaded and stored in C.T. Male’s

electronic project directory.

Upwind VOC STEL concentrations will be measured at the start of the work day

and periodically thereafter employing a handheld MiniRae 3000 VOC monitor to

evaluate the Site’s background conditions. The upwind VOC STEL readings will be

manually recorded for future reference and reporting.

• If the ambient air concentration of total organic vapors opposite the walls of

occupied structures exceeds 1 ppm above background for the 15-minute

average, work activities will be temporarily halted, and monitoring will be

conducted within the occupied structure.

• If the ambient air concentration of total organic vapors at the downwind

perimeter of the work area or exclusion zone (not including the occupied

structures) exceeds 5 parts per million (ppm) above background for the 15-

minute average, work activities will be temporarily halted and monitoring

continued. If the total organic vapor level readily decreases (per

instantaneous readings) below 5 ppm over background, work activities can

resume with continued monitoring.

• If total organic vapor levels at the downwind perimeter of the work area or

exclusion zone (not including the occupied structures) persist at levels in

excess of 5 ppm over background but less than 25 ppm, work activities will

be halted, the source of vapors identified, corrective actions taken to abate

emissions, and monitoring continued. After these steps, work activities can

resume provided that the total organic vapor level 200 feet downwind of the

exclusion zone or half the distance to the nearest potential receptor or

residential/commercial structure, whichever is less - but in no case less than

20 feet, is below 5 ppm over background for the 15-minute average.


13

• If the organic vapor level is above 25 ppm at the perimeter of the work area,

activities will be shutdown. Work activities will then be evaluated to

determine the source of the organic vapors and the engineering controls

required to reduce/eliminate the organic vapors.

5.5 Hazard Identification and Control

6.0 TRAINING

Site specific training of workers and personnel will be conducted and provided by

the HSO or designee prior to any on-Site activity. The training will specifically

address the activities, procedures, monitoring and equipment for the Site

operations. It will include area and facility layout, hazards, emergency services

(police, hospital, fire, etc.), and review of this HASP. Questions by workers, field

personnel, etc. will be addressed at this time.

Workers and personnel conducting and/or supervising the project must have

attended and successfully completed a 40 Hour Health and Safety Training Course

for Hazardous Waste Operations, an annual 8 hour Refresher Course, and take part

in an employer medical surveillance program in accordance with OSHA 1910.120

requirements, specifically, that the workers have had a medical physical within one

(1) year prior to the date the work begins and that they are physically able to wear a

respirator, and have been fit tested.

Documentation of training and medical surveillance will be submitted to the HSO or

designee prior to the start of any on-site work. Copies of the training certificates are

retained in C.T. Male’s files and are available upon request.


19

7.0 SITE ACCESS

The Pre-Design Investigation and Remedial Action Site work (test pits; test borings;

decommissioning of monitoring wells; soil excavation and backfill; excavation

dewatering; closure of underground tanks, hydraulic lifts and drainage structures;

sample collection) will be performed within the Site boundaries. Vehicular traffic

will enter and exit the Site along the east side of Warburton Avenue; the north, east

and west sides of Cottage Garden Place; and the south side of Wood Place.

Pre-Design Investigation

It is likely that the public or curious bystanders may be present at the time of the

work. The work area will be considered within a 20-foot radius of the test pitting or

test boring activities. Only OSHA trained employees of C.T. Male that are qualified

to do the work and have read and signed this HASP will be allowed within the

work area. Pertinent contractors and subcontractors entering into the work area will

follow their own HASPs and will have the necessary training for the work that they

are performing. During advancement of the test pits or test borings, it will be the

Contractor’s responsibility to install the necessary caution tape and/or fencing

around the test pit or test boring work area or at a minimum, designate personnel to

intercept persons from approaching the work area.

Remedial Action

It is likely that the public or curious bystanders may be present at the time of the

work. Contractor supplies and equipment will likely be staged on different areas of

the Site dependent on which areas of the Site are being remediated at any given

time. Therefore, based on vehicular ingress/egress, contractor staging areas and the

work area locations, the work area will be considered anywhere within the

boundaries of the Site. Only OSHA trained employees of C.T. Male that are

qualified to do the work and have read and signed this HASP will be allowed

within the Site. Pertinent contractors and subcontractors entering into the work area

will follow their own HASPs and will have the necessary training for the work that

they are performing. Temporary fencing/hazard tape will be installed around open

excavations after hours when C.T. Male or the contractor is not on Site. Security

fencing will be installed around the Site perimeter and security personnel may be


20

engaged by the Contractor to be on-Site during off-hours. The Contractor will be

responsible for preventing and/or limiting unauthorized individuals from entering

the Site during normal work hours.

7.1 Pre-Design Investigation Exclusion, Contaminant Reduction and Support

Zones

During completion of the Pre-Design Investigation, an approximate 20 foot circle

around the immediate work area (test pit location and excavator, test boring location

and direct-push unit) will be considered the Exclusion Zone (area where the Pre-

Design Investigation is to be conducted). The Contamination Reduction Zone (CRZ

- decontamination area), and Support Zone (clean area, everywhere else) will be

established outside the Exclusion Zone, as necessary. The exclusion, contamination

reduction, and support zones during the Pre-Design Investigation have been

identified and designated as follows:

Exclusion Zone - The location of the exclusion zone will be determined in the field

prior to the start of the Pre-Design Investigation work and will vary depending on

the work activities conducted. For the most part, the exclusion zone is anticipated to

be an approximate 20 foot radius around the daily work area. The exclusion zone

perimeter may be delineated with cones and yellow caution tape or equal method,

where applicable. Only authorized persons with proper training and protective

gear will be allowed to enter the exclusion zone, after first going through the CRZ.

If the exclusion zone, as previously explained, changes orientation during the

completion of the work, the HASP will be amended in the field to reflect the change.

Contamination Reduction Zone (CRZ) – The CRZ will be located at the edge of the

exclusion zone, once activities involving test pits or test borings have begun.

Decontamination of the excavator bucket, tooling to advance the test borings and

project personnel will be conducted in this area. Once decontamination of materials

and equipment has been completed, it can be moved through the CRZ to the

Support Zone. As with the exclusion zone, this area will be marked off with stakes

and yellow caution tape or equal method

Support Zone - Area outside of exclusion/contamination reduction zone.

Unauthorized or untrained individuals must remain in this zone.


21

7.2 Remedial Action Exclusion, Contaminant Reduction and Support Zones

During completion of the Remedial Action, an approximate 10 foot perimeter

around the work area will be considered the Exclusion Zone. These work areas will

include the excavation footprint, soil stockpile areas, truck loading areas,

groundwater treatment areas, equipment decontamination areas, staging areas and

remediation-derived waste storage areas. The Contamination Reduction Zone and

Support Zone will be established outside the Exclusion Zone, as necessary. The

exclusion, contamination reduction, and support zone during the remedial action

have been identified and designated as follows:

Exclusion Zone - The location of the exclusion zone will be determined in the field

prior to the start of the remedial action and will vary depending on the work

activities conducted. For the most part, the exclusion zone is anticipated to be an

approximate 10 foot perimeter around open excavations, impacted soil stockpiles,

truck loading areas, groundwater treatment systems, equipment decontamination

areas, staging areas and remediation-derived waste storage areas. The exclusion

zone perimeter may be delineated with temporary fencing, hazard tape, cones or

equal method, where applicable. Only authorized persons with proper training and

protective gear will be allowed to enter the exclusion zone. If the exclusion zone, as

previously explained, changes orientation during the completion of the remedial

action, the HASP will be amended in the field to reflect the change.

Contamination Reduction Zone (CRZ) – If applicable, the CRZ will generally be a

30’± x 30'± area, marked off with stakes and blue and white colored flagging or

equal method, containing the decontamination pad. The location will be

determined in the field prior to the start of work and will vary depending on the

area(s) the work is being conducted. This zone is where decontamination of

personnel and equipment will take place, as necessary, on the basis of the work

being performed. It will be located upwind of the Exclusion Zone, if possible.

Support Zone - Area outside of CRZ and not including the exclusion zone.

Unauthorized or untrained individuals must remain in this zone.


22

8.0 PERSONAL PROTECTION

8.1 Level of Protection

Based on evaluation of the potential hazards, the minimum level of protection to be

worn by workers during implementation of the Pre-Design Investigation and

Remedial Action is defined as Level D protection, and will be controlled by the HSO

or designee.

The minimum level D protective equipment will consist of field clothes, rubber or

nitrile gloves, hard hats, ear plugs or muffs, safety glasses, and steel toe safety boots.

As appropriate, this level of protection may be modified to include polylaminated

Tyvek suits, coveralls, leg chaps, or a face shield for additional protection.

Both full-face and half-face air purifying respirators should be readily available.

Appropriate combination organic vapor and particulate cartridge filters will be

available at the Site, to use, if necessary with the air purifying respirators.

If required, level C protective equipment will consist of the items listed for Level D

protection with the added protection of either a negative pressure air purifying half-

face or full-face respirator with combination organic vapor and particulate air

cartridges, chemical resistant clothing, inner and outer chemically resistant gloves

(i.e. solvent resistant nitrile, PVC/nitrile), boot covers, and chemical resistant safety

boots/shoes.

Level B is not anticipated, but if required, level B protective equipment will consist

of the items listed for Level C protection except a self-contained breathing apparatus

(SCBA) will be worn depending on the level of contaminants present in the work

zone, and polylaminated Tyvek suits will be required. When Site conditions

warrant the need for level B protective equipment, work will cease and the project

will be re-evaluated to determine if engineering controls could reduce or eliminate

the need for upgrading to Level B protection. Work will not resume under Level B

protection until the engineering evaluation is completed and it is determined that

engineering controls can mitigate the need for Level B protection.


23

8.2 Safety Equipment

Clearly marked basic emergency and first aid equipment will be available at an area

25

10.0 DECONTAMINATION PROCEDURES

10.1 Personnel Decontamination Procedures

Decontamination procedures will be carried out by all personnel leaving the

Exclusion Zone (except under emergency evacuation). The amount of

decontamination performed will be dependent on the level of personal protection

currently being worn within the exclusion zone. Based on the tasks to be conducted,

level D protective equipment is anticipated. The minimum level D protective

equipment will consist of field clothes, nitrile or rubber gloves, hard hats, ear plugs

or muffs, safety glasses, and steel toe safety boots. The decontamination procedures

for level D protection are provided below.

1. Remove any gross soils from boots and clothing prior to exiting the Exclusion

Zone. For the pre-design investigation work, return the gross soils to the test

pit or test boring from which they originated from. For the remedial action,

return the gross soils to portions of the excavation which require further

excavation, deposit in the soil/fill stockpile and/or deposit into trucks that

will be transporting the impacted fill/soil to the disposal facility.

2. Remove nitrile or rubber gloves, and tyvek suit (if worn) and deposit in

designated trash bags.

In the event that higher levels of protection are required, the following general

decontamination procedures will be followed.

1. Do not remove respiratory protection until all of the following steps

have been completed.

2. Clean outer protective gloves and outer boots, if worn, with water

(preferably with a pressurized washer) over designated wash tubs in

the exclusion zone to remove the gross amount of contamination.

3. Deposit equipment used (tools, sampling devices, and containers) at

designated drop stations - on plastic drop sheets or in plastic lined

containers.

4. Rinse outer boots or boot covers, if worn, and gloves with clean water

in designated rinse tubs. Remove outer boots if worn and gloves and


26

deposit in designated area to be determined in the field for use the

next day or when necessary. If disposable outer boots are worn,

remove and discard in designated container.

5. Remove hard hat & safety glasses, rinse with clean water as necessary

and deposit in designated area for use the next day or when necessary.

6. Remove Tyvek suit, if worn, and discard in designated container.

Remove respirator at this time, if used; wash and rinse with clean

water. Organic vapor and particulate cartridges, when used, will be

replaced daily. Used cartridges will be discarded in the designated

waste container. Remove inner gloves and discard in designated

container.

10.2 Equipment and Sample Containers Decontamination

All decontamination will be completed by personnel in protective gear appropriate

for the level of protection determined by the Site HSO or designee. Manual

sampling equipment and appurtenances including trowels, hand augers, shovels,

macro-core samplers, etc. that come into contact with the Site’s fill/soil and/or

groundwater will be cleaned with a tap water/detergent wash and a tap water

rinse. The sampling equipment will be washed after each sample is collected. The

wash and rinse water will be stored in Department of Transportation (DOT)

approved containers for characterization and off-site disposal at a permitted

disposal facility.

Excavation equipment (i.e., rubber-tire backhoe or track excavator) which comes

into contact with the Site’s soils or groundwater will be decontaminated with a high

pressure/hot water wash. The decontamination procedure will focus on portions of

the equipment that has come into contact with the Site’s soils or groundwater such

as the bucket, tracks and tires. The cleaning will be performed at the completion of

excavation activities and the used cleaning liquids will be stored in DOT approved

containers for characterization and off-site disposal at a permitted disposal facility.

Groundwater treatment system tubing, piping, gauges, the interiors of the holding

tanks/frac tanks and appurtenances that come into contact with impacted

groundwater will be decontaminated with a high pressure/hot water wash. The


27

cleaning will be performed at the completion of groundwater treatment activities

and the used cleaning liquids will be stored in DOT approved containers for

characterization and off-site disposal at a permitted disposal facility.

Exterior surfaces of sample containers will be wiped clean with disposable wipes in

the decontamination/support zone and transferred to a clean cooler for

transportation or shipment to the analytical laboratory. Sample identities will be

noted and checked off against the chain-of-custody record. The disposable wipes

will be placed in the designated disposal container and disposed of as solid waste.


28

11.0 EMERGENCY RESPONSE PROCEDURES

THE PROJECT EMERGENCY COORDINATOR IS:

Site Health and Safety Officer (HSO) Rosaura Andújar-McNeil

The following standard emergency procedures will be used by on-Site personnel.

The Project Manager and HSO shall be notified of any on-Site emergencies and be

responsible for assuring that the appropriate procedures are followed.

11.1 Personal Injury

Emergency first aid shall be administered on-Site as deemed necessary and only by

a trained individual, if available at the Site. If a trained individual is not available

on-Site, decontaminate, if feasible, and transport individual to nearest medical

facility (Saint Joseph’s Medical Center). The HSO will supply medical data sheets to

appropriate medical personnel and be responsible for completing the incident

report. If the HSO is injured or controlling the emergency situation, the medical

data sheets are available in Appendix A of this HASP.

11.2 Personal Exposure

The recommended response to worker exposure from contaminants on-Site includes

the following:

SKIN CONTACT: Use generous amounts of soap and water. Wash/rinse affected

area thoroughly, then provide appropriate medical attention, as

necessary.

EYE CONTACT: Wash eyes thoroughly with potable water supply provided on

Site. Eyes should be rinsed for at least 15 minutes subsequent to

chemical contamination. Provide medical attention, as

necessary.

INHALATION: Move worker to fresh air and outside of the work zone and/or,

if necessary, decontaminate and transport to hospital (Saint

Joseph’s Medical Center). If respirator use is implemented at


29

the time of inhalation, the worker must not remove the

respirator until completely away from the work zone.

INGESTION: Decontaminate, if feasible, and transport to hospital (Saint

Joseph’s Medical Center).

PUNCTURE WOUND OR

LACERATION: Provide first aid at the Site and if wound needs medical

attention, decontaminate, if feasible, and transport to hospital

(Saint Joseph’s Medical Center).

If the affected worker is exposed to contaminants on-Site and the injury or accident

prevents decontamination of the individual, the emergency responders must be

notified of this condition and the exposure must be kept to a minimum.

11.3 Potential or Actual Fire or Explosion

Immediately evacuate area in the event of potential or actual fire or explosion.

Notify the local fire and police departments, and other appropriate emergency

response groups, as listed in Section 1.2. Perform off-site decontamination and

contain wastes for proper disposal. If a fire or explosion occurs, all on-Site

personnel must meet in the pre-designated rally point of the Site (established by the

HSO or designee) for an accurate head count.

11.4 Equipment Failure

Should there be any equipment failure, breakdown, etc. the Project Manager and

HSO shall be contacted immediately. The Project Manager or the HSO will make

every effort to replace or repair the equipment in a timely manner.

11.5 Spill Response

The Site HSO or designee shall initiate a corrective action program with the

subcontractors in the event of an accidental release of a hazardous material,

suspected hazardous material and/or petroleum products. The HSO or designee

will act as the Emergency Coordinator with the subcontractors for the purposes of:

spill prevention; identifying releases; implementing clean up measures; and

notification of appropriate personnel.


30

The corrective action program will be implemented by the HSO and subcontractor

to effectively control and minimize any impact accidental releases may have to the

environment.

Effective control measures will include:

• Preliminary assessment of the release.

• Control of the release source.

• Containment of the released material.

• Effective clean-up of the released material.

Potential sources of accidental releases include: hydraulic oil spills or petroleum

leaks from heavy equipment; cooling oils (potentially PCB containing) from

electrical equipment handling and cleaning; and spills from drums, vats, vessels,

and tanks. The HSO/Emergency Coordinator in conjunction with the subcontractor

shall respond to an accidental release in the following manner:

• Identify the character, source, amount and area affected by the release.

• Have subcontractor take all reasonable steps to control the release.

• Notify the NYSDEC Spill Hotline at 1-800-457-7362.

• Notify NYSDEC Project Manager Scott Deyette and 178 Warburton

Limited Partnership.

• Contain the release with sorbent material which should include

speedi-dry, spill socks and sorbent pads.

• Prevent the release from entering sensitive receptors (i.e., catch basins

and surface water) using the specified sorbent material or sandbags.

• Coordinate cleanup of the released material.

• Oversee proper handling and storage of contaminated material for

disposal.

At no time should personal health or safety be compromised or jeopardized in an

attempt to control a release. All health and safety measures as outlined in this

HASP should be adhered to.


31

12.0 ADDITIONAL WORK PRACTICES

Workers will be expected to adhere to the established safety practices. Work on the

project will be conducted according to established protocol and guidelines for the

safety and health of all involved. The following will be adhered to:

- Employ the buddy system when possible, and for those work tasks (i.e.,

entering abandoned buildings, traversing uneven, vacant land, etc.) which

require it. Establish and maintain communications.

- Minimize contact with potentially contaminated soil, soil vapor and

groundwater.

- Employ disposable items when possible to minimize risks during

decontamination and possible cross-contamination during sample handling.

- Smoking, eating, or drinking in the Exclusion and CRZ will not be allowed

(to prevent oral ingestion of potential on-site contaminants).

- Avoid heat and other work stress related to wearing personal protective

equipment. Take breaks as necessary and drink plenty of fluids to prevent

dehydration.

- Withdrawal from a suspected or actual hazardous situation to reassess

procedures is the preferred course of action.

- The removal of facial hair (except mustaches) prior to working on-Site will be

required to allow for a proper respiratory face piece fit, if necessary.

- The Project Manager, the HSO, and sampling, pre-design investigation and

remedial field personnel shall maintain records recording daily activities,

meetings, facts, incidents, data, etc. relating to the project. These records will

remain at the project Site during the full duration of the project so that

replacement personnel may add information while maintaining continuity.

These daily records will become part of the permanent project file.

APPENDIX A

COMMUNITY AIR MONITORING PLAN


Appendix 1A New York State Department of Health

Generic Community Air Monitoring Plan

Overview

A Community Air Monitoring Plan (CAMP) requires real-time monitoring for volatile organic compounds (VOCs) and particulates (i.e., dust) at the downwind perimeter of each designated work area when certain activities are in progress at contaminated sites. The CAMP is not intended for use in establishing action levels for worker respiratory protection. Rather, its intent is to provide a measure of protection for the downwind community (i.e., off-site receptors including residences and businesses and on-site workers not directly involved with the subject work activities) from potential airborne contaminant releases as a direct result of investigative and remedial work activities. The action levels specified herein require increased monitoring, corrective actions to abate emissions, and/or work shutdown. Additionally, the CAMP helps to confirm that work activities did not spread contamination off-site through the air.

The generic CAMP presented below will be sufficient to cover many, if not most, sites. Specific requirements should be reviewed for each situation in consultation with NYSDOH to ensure proper applicability. In some cases, a separate site-specific CAMP or supplement may be required. Depending upon the nature of contamination, chemical- specific monitoring with appropriately-sensitive methods may be required. Depending upon the proximity of potentially exposed individuals, more stringent monitoring or response levels than those presented below may be required. Special requirements will be necessary for work within 20 feet of potentially exposed individuals or structures and for indoor work with co-located residences or facilities. These requirements should be determined in consultation with NYSDOH.

Reliance on the CAMP should not preclude simple, common-sense measures to keep VOCs, dust, and odors at a minimum around the work areas.

Community Air Monitoring Plan

Depending upon the nature of known or potential contaminants at each site, real-time air monitoring for VOCs and/or particulate levels at the perimeter of the exclusion zone or work area will be necessary. Most sites will involve VOC and particulate monitoring; sites known to be contaminated with heavy metals alone may only require particulate monitoring. If radiological contamination is a concern, additional monitoring requirements may be necessary per consultation with appropriate DEC/NYSDOH staff.

Continuous monitoring will be required for all ground intrusive activities and during the demolition of contaminated or potentially contaminated structures. Ground intrusive activities include, but are not limited to, soil/waste excavation and handling, test pitting or trenching, and the installation of soil borings or monitoring wells.

Periodic monitoring for VOCs will be required during non-intrusive activities such as the collection of soil and sediment samples or the collection of groundwater samples from existing monitoring wells. APeriodic@ monitoring during sample collection might reasonably consist of taking a reading upon arrival at a sample location, monitoring while opening a well cap or


overturning soil, monitoring during well baling/purging, and taking a reading prior to leaving a sample location. In some instances, depending upon the proximity of potentially exposed individuals, continuous monitoring may be required during sampling activities. Examples of such situations include groundwater sampling at wells on the curb of a busy urban street, in the midst of a public park, or adjacent to a school or residence.

VOC Monitoring, Response Levels, and Actions

Volatile organic compounds (VOCs) must be monitored at the downwind perimeter of the immediate work area (i.e., the exclusion zone) on a continuous basis or as otherwise specified. Upwind concentrations should be measured at the start of each workday and periodically thereafter to establish background conditions, particularly if wind direction changes. The monitoring work should be performed using equipment appropriate to measure the types of contaminants known or suspected to be present. The equipment should be calibrated at least daily for the contaminant(s) of concern or for an appropriate surrogate. The equipment should be capable of calculating 15-minute running average concentrations, which will be compared to the levels specified below.

1. If the ambient air concentration of total organic vapors at the downwind perimeter of the work area or exclusion zone exceeds 5 parts per million (ppm) above background for the 15-minute average, work activities must be temporarily halted and monitoring continued. If the total organic vapor level readily decreases (per instantaneous readings) below 5 ppm over background, work activities can resume with continued monitoring.

2. If total organic vapor levels at the downwind perimeter of the work area or exclusion zone persist at levels in excess of 5 ppm over background but less than 25 ppm, work activities must be halted, the source of vapors identified, corrective actions taken to abate emissions, and monitoring continued. After these steps, work activities can resume provided that the total organic vapor level 200 feet downwind of the exclusion zone or half the distance to the nearest potential receptor or residential/commercial structure, whichever is less - but in no case less than 20 feet, is below 5 ppm over background for the 15-minute average.

3. If the organic vapor level is above 25 ppm at the perimeter of the work area, activities must be shutdown.

4. All 15-minute readings must be recorded and be available for State (DEC and NYSDOH) personnel to review. Instantaneous readings, if any, used for decision purposes should also be recorded.

Particulate Monitoring, Response Levels, and Actions

Particulate concentrations should be monitored continuously at the upwind and downwind perimeters of the exclusion zone at temporary particulate monitoring stations. The particulate monitoring should be performed using real-time monitoring equipment capable of measuring particulate matter less than 10 micrometers in size (PM-10) and capable of integrating over a period of 15 minutes (or less) for comparison to the airborne particulate action level. The equipment must be equipped with an audible alarm to indicate exceedance of the action level. In addition, fugitive dust migration should be visually assessed during all work activities.


1. If the downwind PM-10 particulate level is 100 micrograms per cubic meter (mcg/m3) greater than background (upwind perimeter) for the 15-minute period or if airborne dust is observed leaving the work area, then dust suppression techniques must be employed. Work may continue with dust suppression techniques provided that downwind PM-10 particulate levels do not exceed 150 mcg/m3

above the upwind level and provided that no visible dust is migrating from the work area.

2. If, after implementation of dust suppression techniques, downwind PM-10 particulate levels are greater than 150 mcg/m3 above the upwind level, work must be stopped and a re-evaluation of activities initiated. Work can resume provided that dust suppression measures and other controls are successful in reducing the downwind PM-10 particulate concentration to within 150 mcg/m3 of the upwind level and in preventing visible dust migration.

3. All readings must be recorded and be available for State (DEC and NYSDOH) and County Health personnel to review.

December 2009

SPECIAL REQUIREMENTS COMMUNITY AIR MONITORING PROGRAM

Special Requirements for Work within 20 feet of Potentially Exposed Individuals or Structures

When work areas are within 20 feet of potentially exposed populations or occupied structures, the continuous monitoring locations for VOCs and particulates must reflect the nearest potentially exposed individuals and the location of ventilation system intakes for nearby structures. The use of engineering controls such as vapor/dust barriers, temporary negative-pressure enclosures, or special ventilation devices should be considered to prevent exposures related to the work activities and to control dust and odors. Consideration should be given to implementing the planned activities when potentially exposed populations are likely to be lower, such as during weekends or evening hours in non-residential settings.

• If total VOC concentrations opposite the walls of occupied structures or next to intake vents exceed 1 ppm, monitoring should occur within the occupied structure(s). Background readings in the occupied spaces must be taken prior to commencement of the planned work. Any unusual background readings should be discussed with NYSDOH prior to commencement of the work.

• If total particulate concentrations opposite the walls of occupied structures or next to intake vents exceed 150 mcg/m3, work activities should be suspended until controls are implemented and are successful in reducing the total particulate concentration to 150 mcg/m3 or less at the monitoring point.

• Depending upon the nature of contamination and remedial activities, other parameters (e.g., explosivity, oxygen, hydrogen sulfide, carbon monoxide) may also need to be monitored. Response levels and actions should be pre-determined, as necessary for each site.

Special Requirements for Indoor Work with Co-Located Residences or Facilities

Unless a self-contained, negative-pressure enclosure with proper emission controls will encompass the work area, all individuals not directly involved with the planned work must be absent from the room in which the work will occur. Monitoring requirements shall be as stated above under “Special Requirements for Work within 20 Feet of Potentially Exposed Individuals or Structures” except that in this instance “nearby/occupied structures” would be adjacent occupied rooms. Additionally, the location of all exhaust vents in the room and their discharge points, as well as potential

vapor pathways (openings, conduits, etc.) relative to adjoining rooms, should be understood and the monitoring locations established accordingly. In these situations, it is strongly recommended that exhaust fans or other engineering controls be used to create negative air pressure within the work area during remedial activities. Additionally, it is strongly recommended that the planned work be implemented during hours (e.g. weekends or evening) when building occupancy is at a minimum.

Steve‐ I have reviewed the proposal for the approach to collect samples for Emerging Contaminants in soil at the CPG Phase 5 site. The samples will be collected in‐situ prior to remediation during the waste characterization sampling. I strongly advise that the protocols for sample collection are strictly followed, as “anomalies” in sample results for these contaminants will not be ignored, and the only recourse will be to resample. Once all of the data has been received a summary report should be forwarded to the Department for approval prior to any intrusive (excavation) work beginning on the site. The proposal is approved; please provide notice as to when the sampling will take place. I have also attached our most recent (January 2020) PFAS Sampling Guidelines for your reference. Let me know if you have any questions.

ATTENTION: This email came from an external source. Do not open attachments or click on links from unknown senders or

unexpected emails.

Hi Scott, In regard to the Department’s request that confirmatory post‐excavation soil samples from the remedial action at CPG5 also be analyzed for the emerging contaminants (ECs) 1,4‐dioxane and the NYSDEC list of 21 PFAS (January 2020) inaddition to the analytical parameters specified in the RWP, C.T. Male proposes the following sampling approach to address ECs for your review and consideration.

2

1,4‐dioxane 1,4‐dioxane is an analyte that is included in the laboratory’s regular analyses of SVOCs in soil by EPA Method 8270 (notSIM). The laboratory has indicated that the reporting limit (RL) and method detection limit (MDL) for 1,4‐dioxane in soil by method 8270 is RL= 25.05 ug/kg (0.025 mg/kg) and MDL=7.682 ug/kg (0.0076 mg/kg); which is below the action levelof 0.1 mg/kg (ppm) for 1,4‐dioxane in soil. As such, 1,4‐dioxane will be analyzed for in confirmatory post‐excavation samples. Sampling of 1,4‐dioxane is anticipated to occur during the collection of confirmatory post‐excavation samples during the remedial action. PFAS 25% of the confirmatory post‐excavation floor soil sample locations will be analyzed for PFAS by EPA Method 537.1Modified using isotopic dilution techniques. Reporting limits for PFOA and PFOS in soil samples are targeted to be lessthan 0.5 ug/kg. Reporting limits for PFOA and PFOS in aqueous samples are targeted to be less than 2 ng/L. Per the attached figure, 72 +/‐ 900 square foot post‐excavation sampling cells (highlighted in red) are identified. 18 (25%) of the confirmatory post‐excavation cells will be sampled and analyzed for PFAS. The proposed PFAS sampling locations are shown on the attached drawing which provide overall coverage of the Site. Due to anticipated delayed laboratory turnaround times for PFAS analyses and the historic accelerated constructionschedule of remediation quickly followed by redevelopment at the other CPG phases (I – IV), we propose to perform theend point (floor) soil sampling for PFAS during the waste characterization sampling activity (anticipated in February/March2020), prior to the commencement of soil remediation activities. End‐point side wall sampling for PFAS will be conducted during the remedial action from side walls that do not abut areas of prior remediation (i.e. CPG III and IV). The attached drawing also depicts the waste characterization cells (highlighted in green). The collection of native soils for PFAS analyses will be performed in the following manner. ‐Soil samples will be collected via direct‐push methods employing a track‐mounted Geoprobe unit. ‐The samples will be collected with a decontaminated (alconox/laboratory provided PFAS‐free water wash and laboratoryprovided PFAS‐free water rinse) macro‐core sampler with new, acetate liners. ‐Each sample will consist of approximately one (1) vertical foot of native soil immediately beneath the overlying fill/soil material. ‐Each recovered soil sample will be homogenized in a decontaminated stainless‐steel bowl using a decontaminated stainless steel or HDPE spoon. ‐One (1) set of QA/QC samples will be collected per each 20 samples collected. These samples will include a trip blank, duplicate sample, matrix spike, matrix spike duplicate and equipment blank of the stainless steel bowl and Geoprobesampling barrel. ‐The analytical results will be reported as a Category B deliverable for validation by an independent third party data validator. ‐The analytical results report and table will be provided to the Department. ‐Field sampling will generally conform to the Field Sampling Plan contained in Appendix A of the June 13, 2017 (RevisedJanuary 2018) Remedial Investigation Work Plan for the Cottage Place Gardens Phase 5 Parcel, and Guidelines for Samplingand Analysis of PFAS – Under NYSDEC’s Part 375 Remedial Programs (January 2020). Please let us know if this sampling approach and plan is acceptable to the Department. Thanks.
