1.0 SUMMARY

Leidos (NISC III), in support of the Federal Aviation Administration (FAA), presents this

Phase I Environmental Due Diligence Audit (EDDA) report for the ACV Outer Marker (OM)

located off of Lucchesi Road, Arcata, California 59421. The former ACV OM has been

decommissioned and the site has been restored. The former ACV OM had been located on an

approximately 0.31-acre parcel of land. The parcel of land and any buildings, structures, and

improvements on the parcel are hereafter referred to as the “Subject Property” for the purposes

of this report. The parcel of land is owned by the United States of America, and was used by the

FAA.

Records were obtained from various agencies to gather historical information and documentation

pertaining to potential environmental liabilities associated with the subject and surrounding

properties. A database search of federal and state environmental records was performed to

determine if neighboring or adjacent properties have the potential to adversely affect the Subject

Property.

Details of the findings associated with the Subject Property are provided in Section 8.0 of this

report. This Phase I EDDA has revealed no recognized environmental conditions (as defined by

ASTM International (ASTM) Standard E1527-13) in connection with the Subject Property.

2.0 INTRODUCTION

The Subject Property has been decommissioned, restored, and is excess real property. Due to the

anticipated sale of the Subject Property, the FAA Facility Disposition program requested a

Phase I EDDA to be performed for the Subject Property.

2.1 Purpose

The purpose of this Phase I EDDA is to identify, to the extent feasible and subject to the

limitations discussed in this report, recognized environmental conditions and historical

recognized environmental conditions related to the Subject Property.

According to ASTM E1527-13, the term “recognized environmental conditions” is

defined as follows:

the presence or likely presence of any hazardous substances or petroleum products in,

on, or at a property: (1) due to release to the environment; (2) under conditions

indicative of a release to the environment; or (3) under conditions that pose a material

threat of a future release to the environment. De minimis conditions are not

recognized environmental conditions.

According to ASTM E1527-13, the term “historical recognized environmental condition”

is defined as follows:

Page 6: ACV Outer Marker (OM) Lucchesi Road Arcata, California

ACV OM Phase I EDDA 2

a past release of any hazardous substances or petroleum products that has occurred in

connection with the property and has been addressed to the satisfaction of the

applicable regulatory authority or meeting unrestricted use criteria established by a

regulatory authority, without subjecting the property to any required controls (for

example, property use restrictions, activity and use limitations, institutional controls,

or engineering controls).

This report serves as documentation of a Phase I EDDA for the Subject Property. The

purpose of this audit is to assist the FAA in exercising due diligence by evaluating

potential environmental liabilities associated with the Subject Property. This audit was

performed in accordance with and within the guidelines set forth in FAA Order

1050.19B, Environmental Due Diligence Audits in the Conduct of FAA Real Property

Transactions and ASTM E1527-13, Standard Practice for Environmental Site

Assessments: Phase I Environmental Site Assessment Process.

2.2 Detailed Scope of Services

A detailed site inspection was conducted on November 14, 2018. The site inspection

consisted of a visual survey of all property grounds, and immediate surrounding areas to

identify recognized environmental conditions. The purpose of the site inspection was to

identify areas such as manufacturing and process areas; chemical storage areas; waste

storage areas; suspected disposal areas; subsurface structures (such as drains, sumps,

septic systems, and tanks); fuel storage areas; electrical equipment which may contain

polychlorinated biphenyls (PCBs); evidence of historical uses; and evidence of spills or

potential releases of hazardous substances (such as stressed vegetation and soil staining).

Records were obtained from various agencies to gather historical information and

documentation pertaining to potential environmental liabilities associated with the

Subject Property and surrounding properties. A database search of federal and state

environmental records was performed to determine if neighboring or adjacent properties

have the potential to adversely affect the Subject Property.

2.3 Significant Assumptions

Leidos (NISC III) is not aware of any significant assumptions.

2.4 Limitations and Exceptions

This Phase I EDDA was performed in accordance with the ASTM Standard E1527-13

and FAA Order 1050.19B. The methodologies contained in these standards and orders

include, among other things, interviews with individuals familiar with the Subject

Property, site inspection, and historical records review. Information obtained during the

interviews and site inspection was recorded and reviewed before it was included in this

Phase I EDDA report. All information that was obtained during the site investigation and

subsequently included within this Phase I EDDA is assumed to be reliable. Not all such

information, however, is susceptible to independent verification. Data from additional

government databases was obtained and reviewed using accepted industry standards and

Page 7: ACV Outer Marker (OM) Lucchesi Road Arcata, California

ACV OM Phase I EDDA 3

practices. The conclusions summarized herein are based on the limited observations and

review described within this submittal at the time the Phase I EDDA was conducted.

Future events at the Subject Property or the surrounding properties may alter these

findings.

Performing a Phase I EDDA in accordance with ASTM Standard E1527-13 and FAA

Order 1050.19B is intended to reduce, but not eliminate, uncertainty regarding the

potential for recognized environmental conditions in connection with a property, and both

practices recognize reasonable limits of time and cost.

2.5 Special Terms and Conditions

Leidos (NISC III) is not aware of any special terms or conditions.

2.6 User Reliance

Leidos (NISC III) is not aware of any user reliance issues.

One ENVIROSTOR site within 1.0 miles of the Subject Property:

One ENVIROSTOR site, U.S. Coast Guard Air Station Arcata Airport, was identified in

the EDR Report. Upon further review it was determined that the site was located at the

Arcata Airport, approximately 6.0 miles from the Subject Property. Based on the site’s

location, this site does not likely present a risk to the Subject Property.

One LUST site within 0.5 miles of the Subject Property:

There are two LUST sites, Humboldt Bay Muni Water Essex and HBMWD Essex

Operations Center/Humboldt Bay Muni Water, identified within the EDR report. Based

on further investigation it was concluded that the two sites identified are the same site,

therefore there is only one LUST site. The site, Facility ID/RB Case Number: 1THU225,

contained a gasoline UST of which the size was not reported. Due to potential soil

contamination a case was opened at the site on February 2, 1990. A site assessment was

completed on February 22, 1990 followed by remediation, an additional site assessment,

and verification monitoring on July 10, 1990. The case was closed on July 11, 1990.

Due to the case closure, this site likely does not likely present a risk to the Subject

Property.

Orphan Sites:

There are no Orphan Sites identified in the EDR report.

5.2 Additional Environmental Record Sources

Local Records

Leidos (NISC III) reviewed pertinent local files and conducted interviews with FAA

personnel. Other information was compiled using Internet sources as described in this

section.

National Wetlands Inventory and Flood Insurance Rate Maps

A wetlands map was obtained from the National Wetlands Inventory (NWI) website

(http://www.fws.gov/wetlands/). Refer to Section 16.4.4 for the NWI map. A review of

the NWI Map indicates that wetlands are not located on the Subject Property. The

nearest wetland is a freshwater forested/shrub wetland approximately 0.32 miles north,

followed by a riverine approximately 0.35 miles north of the Subject Property.

The Flood Insurance Rate Map (FIRM) was obtained from the Federal Emergency

Management Agency (FEMA) website (https://msc.fema.gov/). Refer to Section 16.4.5

for FIRM. According to the map (number 06023C0695F, effective date November 4,

2016), the Subject Property lies within Zone X, which are areas of minimal flood hazard.

A review of information provided in the Natural Resource Conservation Web Soil Survey

website (http://websoilsurvey.nrcs.usda.gov/), indicate the soils for the Subject Property

consist primarily of Timmons and Lepoil soils. Section 5.4 of this report provides an

Page 14: ACV Outer Marker (OM) Lucchesi Road Arcata, California

ACV OM Phase I EDDA 10

additional soil report. See Section 16.4.6 for a detailed discussion on Timmons and

Lepoil soils.

5.3 Physical Setting Source(s)

The properties surrounding the Subject Property are wooded areas and rural residential

properties. The immediately surrounding area slopes to the north-northeast. According

to the EDR Radius Report, elevations in the vicinity of the Subject Property range from

35 to 471 feet above sea level.

5.4 Historical Use Information on the Property

Prior to being developed, the area of the Subject Property appeared wooded areas. In

1951 the site was developed as an OM site. Use of the site as ACV OM continued until

being decommissioned in April 2014. In September 2016, the equipment and structures

were removed and the site was restored.

Topographic Map Review

As a part of the investigation of the Subject Property, the U.S. Geological Survey

(USGS) topographic maps for 1933, 1942, 1951, 1959, 1972, and 2012 were obtained

from EDR. Copies of the topographic maps are provided in Section 16.4.3.

5.5 Historical Use Information on Adjoining Properties

Adjoining properties historically and continue be to wooded areas and rural residential

properties.

6.0 SITE INSPECTION

On November 14, 2018, Leidos (NISC III) conducted a detailed site inspection of the Subject

Property and adjacent properties to determine their environmental condition. See Section 16.3 to

review the site inspection photographs. The following sections are based on observations made

by the environmental professional during the site inspection.

6.1 Methodology and Limiting Conditions

Leidos (NISC III) contacted Norbert Peterson, Arcata SSC Manager, David Ackroyd,

Arcata SSC Coordinator, and Kevin Patton, Arcata ATSS, to verify the removal of all

limiting conditions and to schedule the site inspection. As the Subject Property is readily

accessible, no escort was required for the site inspection.

6.2 General Site Setting

The Subject Property is surrounded by wooded areas and rural residential properties.

6.3 External Observations

The Subject Property has been restored and no structures remain. The formerly fenced

plot where the equipment shelter building and antenna had been located is covered

primarily with gravel and dirt. The ACV OM site plot is located east of Lucchesi Road.

Adjacent to and off of Lucchesi Road is a pole-mounted transformer that formerly

serviced the Subject Property and a barbed wire fence that remains. No signs of leaks

from the transformer were observed. No stressed vegetation was observed at or near the

base of the power pole.

A piece of assumed ground cable was observed. The piece of cable appeared to be

historically discarded as possibly part of the restoration process. Sparse pieces of trash

were observed within the formerly fenced portion of the Subject Property. The material

is considered to be de minimis. See Site Plan in Section 16.2 and Site Photographs in

Section 16.3

The site inspection did not identify any manufacturing and process areas; chemical

storage areas; hazardous waste storage areas; suspected disposal areas; subsurface

structures such as drains, sumps, septic systems, and tanks; evidence of historical uses;

and soil staining or impacted vegetation.

Page 20: ACV Outer Marker (OM) Lucchesi Road Arcata, California

ACV OM Phase I EDDA 16

A site plan is provided in Section 16.2 and photographs of the Subject Property are

provided in Section 16.3.

6.4 Interior Observations

The Subject Property contains no structures with interiors. Interior observations are not

applicable.

7.0 INTERVIEWS

7.1 Interview with Owner

No interviews were conducted with the property owners.

7.2 Interview with Site Manager

Interviews were conducted with FAA Arcata SSC Manager Norbert Peterson and with

FAA Arcata SSC Coordinator David Ackroyd via telephone and email prior to the site

inspection. Neither indicated knowledge of any current or historical adverse

environmental conditions at or around the Subject Property.

7.3 Interviews with Occupants

There are no occupants as the site has been decommissioned and the site was never a

manned facility.

7.4 Interviews with State and/or Local Officials

Research and investigation efforts provided information required for this Phase I.

Therefore, no interviews with state or local officials were deemed necessary.

7.5 Interviews with Others

The Western Service Area (WSA) Real Estate Contracting Officer (RECO) was

contacted by Leidos (NISC III). The RECO provided available real estate documents

including the legal description and Airspace Easement.

8.0 FINDINGS

We have performed a Phase I Environmental Site Assessment in conformance with the scope and

limitations of the applicable ASTM Standard E1527-13, and FAA Order 1050.19B, of ACV OM

located off of Lucchesi Road, Arcata, California 59421.

As detailed in Section 5.1, there was one site listed on the ENVIROSTOR database and two

LUST sites identified in the EDR report. Upon further review it was determined that the site

Page 21: ACV Outer Marker (OM) Lucchesi Road Arcata, California

ACV OM Phase I EDDA 17

listed on the ENVIROSTOR database was located at the Arcata Airport, approximately 6.0 miles

from the Subject Property. Based on additional research it was determined that the two LUST

sites are the same site, the Humboldt Bay Muni Water Essex. Based on potential soil

contamination, a site case was opened in February 1990 and closed on July 1990 following a site

remediation in February 1990. Based on the distant of the ENVIROSTOR site and case closure

following remediation at the Humboldt Bay Muni Water Essex, these sites likely do not present a

risk to the Subject Property. As indicated in Section 5.1, no orphan sites were identified in the

EDR report.

9.0 OPINIONS

The site inspection and records review did not reveal any recognized environmental conditions in

connection with the Subject Property. Also, there is no indication that FAA activities on the

Subject Property have contributed to any environmental concerns on adjacent properties.

Furthermore, there is no indication that operations and conditions on adjacent properties have

caused any adverse environmental effects to the Subject Property.

10.0 CONCLUSIONS

We have performed a Phase I Environmental Site Assessment in conformance with the scope and

limitations of ASTM Standard E1527-13, and FAA Order 1050.19B, of the ACV OM located off

of Lucchesi Road, Arcata, California 59421. Any exceptions to, or deletions from, this practice

are described in Section 2.4 of this report. This assessment has revealed no evidence of

recognized environmental conditions in connection with the Subject Property.

11.0 DEVIATIONS

This Phase I EDDA was performed with no deletions or deviations from ASTM Standard

E1527-13 and FAA Order 1050.19B, except as specified in Section 12.0.

12.0 ADDITIONAL SERVICES

12.1 Asbestos

No sampling for asbestos containing material (ACM) was done as part of this Phase I

EDDA. According to the Final Demolition and Remediation Investigation Report

Federal Aviation Administration Demolition and Remedial Investigation of Arcata

Locator Outer Marker Arcata, California completed by Ahtna Envrionmental, Inc., an

initial ACM survey was completed on March 30, 2016. An unknown number of samples

were collected and analyzed that showed 12% asbestos in the interior grey putty

penetration. A second ACM survey was completed in August 2016. An unknown

number of samples were collected and analyzed that showed 10% asbestos in the mastics

that was used on roofing edges, roof penetrations, and rood patches. Alliance

Environmental Services, Alliance, was sub-contracted to complete ACM abatement at the

Subject Property. On August 23, 2016 Alliance sealed then removed ACM putty from

Page 22: ACV Outer Marker (OM) Lucchesi Road Arcata, California

ACV OM Phase I EDDA 18

the interior walls and rood mastic, then the roof mastic and insulation was peeled,

scraped, and removed from the rooftop. All ACM material was removed and disposed of

at the Neal Road Landfill facility. This report is available in Appendix E.

12.2 Lead

No sampling for lead based paint (LBP) was conducted as part of this Phase I EDDA.

According to the Final Demolition and Remediation Investigation Report Federal

Aviation Administration Demolition and Remedial Investigation of Arcata Locator Outer

Marker Arcata, California completed by Ahtna Envrionmental, Inc., an initial LBP

survey was completed on March 30, 2016. An unknown number of samples were

collected and analyzed that showed no LBP.

Based on the location of a suspect former UST at the Subject Property, AEI and Kernen

Construction excavated the area around the former UST location. There was no evidence

of a tank or fill material and based on the Photoionization Detector (PID) reading that

were taken during the excavation, no volatile organic compounds were detected. Two

confirmation soil samples were collected at each end of the base of excavation and based

on laboratory analysis, no detection for petroleum hydrocarbons and their constituents

was detected regarding the suspect UST. This report is available in Appendix E.

12.3 Radon

No sampling for radon was conducted as part of this Phase I EDDA. According to the

U.S. Environmental Protection Agency (EPA), Humboldt County, California is a Zone 3

which indicates a predicted average indoor radon screening levels less than 2 pCi/L).

12.4 Endangered and Threatened Species

The goal of the Endangered Species Act is the recovery of listed species to levels where

protection under the Act is no longer necessary. According to the U.S. Fish and Wildlife

Service Environmental Conservation Online System (ECOS), there are twenty-one

threatened or endangered species believed to occur in Humboldt County, California.

These species are provided in Appendix D. No endangered and threatened species or

critical habitats for those species were observed on the Subject Property during the site

inspection.

12.5 Historic Value

The National Historic Preservation Act (NHPA), as amended in 54 United States Code

(USC) 300101 et seq., is the fundamental law for the protection, rehabilitation,

restoration and reconstruction of cultural resources. Section 106 of this Act requires that

federal agencies take measures to protect properties eligible for or included in the

National Register of Historic Places (NRHP). Other statutes, such as the Archaeological

Resources Protection Act (16 USC 470aa-470ii); protect non-structural properties of

historic importance. Research indicates that the Subject Property does not contain any

Page 23: ACV Outer Marker (OM) Lucchesi Road Arcata, California

ACV OM Phase I EDDA 19

structures or areas that qualify for protection as related to the above-referenced statutes.

During the site inspection, no such NRHP sites were observed. A review of the NRHP

did not reveal any information to suggest that the Subject Property would be covered

under the above-referenced statutes.
