REMEDIAL ACTION PLAN Main Street at Fanno Creek

12535 and 12533 SW Main Street Tigard, Oregon

1.0 INTRODUCTION

On behalf of the City Center Development Agency of the City of Tigard (CCDA), Amec Foster Wheeler Environment & Infrastructure, Inc. (Amec Foster Wheeler) has prepared this Remedial Action Plan (RAP) for the Main Street at Fanno Creek cleanup project located at 12535 and 12533 SW Main Street in Tigard, Oregon (Site). The CCDA was awarded two United States Environmental Protection Agency (EPA) Brownfield Cleanup Grants (01J23901) in August 2016 for cleanup of the Site. The Site is identified as a brownfield on the Oregon Department of Environmental Quality (DEQ) Brownfields database. A prospective purchaser agreement (PPA) between the CCDA and the DEQ stipulates cleanup requirements for the Site (DEQ, 2015a). A fact sheet describing the brownfield grant, prior environmental assessment results, and the proposed cleanup is provided in Appendix A. This RAP is supported by two additional documents: Sampling and Analysis Plan (Amec Foster Wheeler, 2017d), and the Quality Assurance Project Plan (Amec Foster Wheeler, 2017e).

Amec Foster Wheeler conducted a series of subsurface environmental investigations at the Site from 2012 through 2014. The results of these investigations are summarized in a Site Characterization Report (AMEC, 2014). The most significant finding was that groundwater beneath the Site is impacted by halogenated volatile organic compounds (HVOCs) at concentrations that exceed DEQ Risk-Based Concentrations (RBCs) (DEQ, 2015b). A draft Analysis of Brownfields Cleanup Alternatives (ABCA) was prepared for the site in November 2015, the objective of which was to present cleanup alternatives for the Site and to guide selection of a remedy based on a systematic evaluation of the alternatives. The preferred remedies, as identified in the ABCA, are demolition of the existing building, excavation and removal of impacted soils that significantly exceed DEQ RBCs, a vapor barrier, and monitored natural attenuation (MNA) for impacted groundwater. DEQ and EPA provided comments to the draft ABCA on October 10, 2016, and November 10, 2016, respectively. The draft ABCA was revised to address these regulator comments and was then posted for a 30-day public comment period, which ended on January 25, 2017. No public comments were received and the ABCA was finalized on February 1, 2017 (Amec Foster Wheeler, 2017b).

DRAFT



The RAP, presented herein, addresses the implementation of the ABCA. This RAP was completed in general accordance with EPA guidelines for conducting removal actions (Code of Federal Regulations [CFR] Title 40 Part 300.415[a][4][i]), and DEQ removal authority (Oregon Administrative Rules [OAR] 340-122-0040).

2.0 SITE DESCRIPTION AND BACKGROUND

2.1 SITE DESCRIPTION

The Site consists of two adjacent properties (tax lots) in downtown Tigard, Oregon, which are located in Section 02, Township 2 South, Range 1 West, on Washington County Tax Assessment Map 2S102AB (Figure 1). Property 1 is located at 12535 SW Main Street (Tax Lot 2000), and Property 2 is located at 12533 SW Main Street (Tax Lot 2100). The Site is developed with three wood-frame commercial buildings with adjoining walls. The westernmost building was constructed partially over Fanno Creek, such that Fanno Creek is directly beneath the western part of the building. This westernmost building is dilapidated and has been vacant for some time. The central and easternmost buildings have been recently vacated.

The Site is situated on approximately 0.44 acres within the downtown historical commercial area of Tigard. The Site is bordered on the southeast by SW Main Street, on the northeast and east by two commercial properties (12519 and 12525 SW Main Street), on the northwest by a vegetated embankment sloping down from Highway 99 W, and on the southwest by Fanno Creek. The Site and the adjoining properties to the east are shown in Figure 2.

2.2 SITE BACKGROUND

The historical uses of the Site have included multiple tenants that used and stored petroleum products and/or solvents. For example, during the 1950s the Site was occupied by the Tigard Planing Mill. It is assumed that small quantities of petroleum products and degreasing solvents may have been stored and used on Site for the equipment operation. Other examples of Site occupants that may have used and stored petroleum products and/or solvents include a tire shop, welding shop, printing shop, and sealant shop. In addition, the easternmost building was formerly occupied by Oregon Drive Axle Supply and Automotive Drivetrain (a repair shop).

Historical Sanborn fire insurance maps indicate that in 1950, the building located to the east of the Site at 12525 SW Main Street was occupied by a welding shop and a printing shop. Materials that could have been used in the welding shop include degreasing solvents and welding components containing metals, such as mercury and lead. Materials that could have been used in the printing

DRAFT



shop include cleaning or degreasing solvents and kerosene for the cleaning plates, rollers, and other printing equipment.

An active dry-cleaning business, known as Tigard Cleaners, is located at 12519 SW Main Street, adjacent to the eastern end of the Site. At the Tigard Cleaners site there have been significant detections of chlorinated solvents in soil gas samples collected from beneath the floor slabs of both the current dry cleaning operation (Building #1 – located next to SW Main Street) and the former dry cleaning operation (Building #2 – located at the back of the property) (Amec Foster Wheeler, 2016). Tigard Cleaners is located up slope, and presumably up gradient, of the Site. A Phase II Environmental Site Assessment (ESA) is currently in progress at the Tigard Cleaners site (Amec Foster Wheeler, 2017c).

Farther to the east is Tyler’s Automotive and Kiss Carwash (12475 SW Main Street and located 300 feet east of the Site). This site was also a former retail fuel and automotive repair station (known as Tigard Shell or Tigard Area Station). Reportedly, a solvent dip tank was previously located in the northwestern portion of the site. Free-phase petroleum product has been identified in the southeastern portion of the site. Tigard Area Station (leaking underground storage tank [LUST] #34-88-0081) and Tigard Shell (LUST #34-02-1149), are listed by DEQ as having cleanup completion dates of October 19, 1989, and November 30, 2006, respectively. Gasoline-contaminated soil and groundwater were discovered during underground storage tank (UST) decommissioning in 1989 and 2002. Free-product recovery occurred in 2003 and a site assessment occurred in 2005. Groundwater contamination did not extend west or southwest along SW Main Street; however, gasoline-range hydrocarbons were detected near the western (presumably southwestern) boundary of the site at concentrations up to 14.7 milligrams per liter (mg/L). Tigard Shell was granted a “No Further Action” (NFA) determination by the DEQ in 2007. The DEQ NFA letter indicates that concentrations of gasoline-range and oil-range hydrocarbons in soil and groundwater exceed applicable risk-based concentrations (RBCs), and the NFA is based on the site not being developed for residential use.

2.3 PRIOR WORK

Several phases of environmental assessment and remedial planning have been conducted at the Site from 2012 through 2017. In October 2012, AMEC Earth and Environmental (now Amec Foster Wheeler) completed a Phase I ESA of the Site. Based on the results of the Phase I ESA, multiple Phase II subsurface investigations were conducted from November 2012 through August 2014, culminating in the submittal of a Site Characterization Report in September 2014 (AMEC, 2014). These investigations included soil, sediment, surface water, groundwater, and soil gas sampling to evaluate whether historical use of the Site and properties up gradient of the Site have affected Site

DRAFT



environmental conditions. After the subsurface investigation work was completed, cleanup plans for the Site were negotiated with the DEQ, and formalized via a PPA. The agreed-upon cleanup plans were then incorporated into an ABCA. The assessment and cleanup planning documents prepared for the Site are listed below:

• Phase I Environmental Site Assessment: Saxony-Pacific Properties, 12535 SW Main Street, Tigard, Oregon dated October 19, 2012 (AMEC, 2012a);

• Phase II Subsurface Investigation: Saxony-Pacific Properties, 12535 SW Main Street, Tigard, Oregon dated November 26, 2012 (AMEC, 2012b);

• Phase II Subsurface Investigation: Saxony-Pacific Properties, 12535 SW Main Street, Tigard, Oregon dated May 30, 2013 (AMEC, 2013); and

• Site Characterization Report: Saxony-Pacific Properties, 12535 SW Main Street, Tigard, Oregon, dated September 26, 2014 (AMEC, 2014).

• Phase I Environmental Site Assessment: Saxony-Pacific Properties, 12535 SW Main Street, Tigard, Oregon dated November, 2015 (Amec Foster Wheeler, 2015).

• Analysis of Brownfield Cleanup Alternatives: Main Street Fanno Creek Properties (aka Saxony-Pacific Properties), Main Street, Tigard, Oregon. (Amec Foster Wheeler, 2017b).

Results of the prior work are best summarized in the Site Characterization Report (AMEC, 2014) and the ABCA (Amec Foster Wheeler, 2017b). Summary tables of investigation analytical results to date are located in Appendix B. Boring logs for the Site are presented in Appendix C.

3.0 REMEDIAL ACTION AREA AND OBJECTIVES

Based on discussions with the DEQ and the requirements of the PPA, the remedial action area and objectives are listed below.

The remedial action area consists of:

• Groundwater with HVOCs in the upland portion of the Site (Figure 3); and

• Soil with HVOCs (source area soils) in the upland portion of the Site.

The remedial action objectives are:

• Prevent direct contact between human receptors and groundwater exceeding applicable risk-based concentrations;

DRAFT



• Prevent direct contact between human receptors and soil exceeding applicable risk-based concentrations;

• Remediate/remove source-area soil to the extent feasible (especially if “hot spots” are encountered following building demolition);

• Prevent HVOC vapors from migrating into indoor air (eliminate the vapor migration pathway); and

• Utilize sustainable (“green”) remediation/removal strategies to the maximum extent practicable.

These remedial objectives will be accomplished by: 1) Building and floor-slab removal, 2) Impacted soil removal, 3) Installation of a passive vapor barrier (if necessary), and 4) Installation of groundwater monitoring wells and performing one year of MNA. A conceptual diagram summarizing the RAP activities is presented as Figure 4.

3.1 REMEDIAL ACTION TEAM ORGANIZATION AND RESPONSIBILITIES

The remedial action team includes CCDA, an as yet to be determined (TBD) General Contractor, a TBD Drilling Contractor, Amec Foster Wheeler (Owner’s Representative and Environmental Consultant), DEQ (Regulatory Agency - State), and EPA (Regulatory Agency - Federal).

Amec Foster Wheeler will assist and oversee the General Contractor, Drilling Contractor, and Archeological Monitor in the implementation of the RAP. Amec Foster Wheeler also will be responsible for documenting and overseeing the proper execution of the RAP. This documentation will be used to prepare two reports, which will be submitted to the DEQ and EPA for review and approval. Contact names and phone numbers for the RAP team are listed in the table below.

4.0 HEALTH AND SAFETY

A copy of the Amec Foster Wheeler Site-Specific Health and Safety Plan (HASP) describing appropriate health and safety measures to be followed at the Site during the implementation of the RAP (Amec Foster Wheeler, 2017a) is provided in Appendix D.

5.0 ACTIVITIES AND APPROACH

5.1 REMEDIAL ACTION PLAN TIMELINE

It is anticipated that RAP activities will be initiated in May 2017. The actual start date will be determined after contract execution and on contractor availability and weather conditions. Ideal weather conditions for the project would be dry to light rain. We anticipate the project duration will be approximately two weeks. Hours of operation during the project will be 7AM to 4PM, Monday through Friday.

The planned sequencing of remedial activities includes: 1) demolition, removal, and off-Site transport of the buildings and floor slabs; 2) excavation, removal, and off-Site transport of non-hazardous soil from the area beneath the floor patch, and possibly other areas; 3) confirmation soil

DRAFT



sampling of the “leave” surfaces within the excavation area(s), and 4) installation of monitoring wells and subsequent sampling of the wells as part of the MNA program.

5.2 DISPOSAL FACILITY PROCUREMENT

Demolition materials and impacted soils will be transported to appropriate landfills. Currently it is anticipated that both HVOC-impacted soils (non-hazardous) and asbestos-containing building materials will be transported to the Waste Management Subtitle D Landfill located in Hillsboro, Oregon (Hillsboro Landfill). Likewise, any other impacted soils (e.g. any soils that do not qualify as “clean fill” (DEQ, 2013; DEQ, 2014) also will be transported to the Hillsboro Landfill. Currently there is no evidence to suggest the presence of any hazardous soils; however, if hazardous soils are discovered during the cleanup process (e.g. field evidence followed by confirmatory laboratory results), then those soils will be transported to the Waste Management Subtitle C Landfill located in Arlington, Oregon. The disposal locations of other building components will be determined by the general contractor, but must be in accordance with the demolition plans and specifications, a copy of which are provided in Appendix E.

5.3 SITE LAYOUT AND TRAFFIC FLOW

An overview of the Site and adjacent properties, along with demolition and staging areas, is depicted in Figure 5. Traffic flow is also depicted on Figure 5, and a hauling route for transporting impacted (non-hazardous) soil and asbestos-containing building materials to the Hillsboro Landfill is presented as Figure 6. A traffic control permit will be obtained by the General Contractor from the CCDA to close the sidewalk and parking shoulder on SW Main Street within the demolition and staging areas (exclusion zone) as depicted in Figure 5.

5.4 EXCLUSION AND DECONTAMINATION ZONE

Before beginning building demolition and excavation of impacted soil, the General Contractor will establish an exclusion zone around the entire work area as shown on Figure 5. The exclusion zone will consist of an 8-foot high cyclone fence with lockable gates. Public access will be restricted into the exclusion zone. Only appropriate personnel in compliance with the HASP will be allowed to enter. An entrance and exit location to the exclusion zone will be established and documented in the daily field logs. At the end of each workday, the entry and exit location within the exclusion zone will be closed and locked to limit the risk to trespassers from entering the exclusion zone.

Equipment may operate freely within the exclusion zone and, except for haul trucks, will not require cleaning while operating within the exclusion zone. When equipment leaves the exclusion area (i.e.

DRAFT



at the end of the project), any equipment that has come in contact with impacted soil will be pressure washed in a designated decontamination area.

Truck loading will occur within a specified loading zone located within the exclusion zone. The loading zone is described in detail in Section 5.5.2.

A pressure washer will be made available within the decontamination zone to remove soil adhered to equipment prior to leaving the loading or exclusion zones. If contaminants of a sticky nature are adhering to equipment (e.g. free oil), then a hot-water pressure washer will be employed to allow for better removal of the material. Water generated from decontaminating equipment will be collected in 55-gallon drums, and sampled for disposal characterization. Street sweeping will be required if off-Site tracking of soil is observed.

5.5 BUILDING DEMOLITION, FLOOR-SLAB REMOVAL, AND EXCAVATED SOIL

MANAGEMENT

Building removal is anticipated to include both deconstruction and demolition methods. Deconstruction and dismantling techniques will be utilized for materials that can be re-used and recycled including: timber, steel beams, and metal components. Deconstruction/dismantling is typically performed with more precision than standard demolition, and therefore can take more time to complete. Deconstruction and demolition activities will be performed utilizing medium to large excavators equipped with dismantlers, shears, hammers, buckets, crushers, and claws. Building removal will start from the perimeter and work inward (start to the northeast and progress towards Fanno Creek), and begin from the roof and trusses and work downward to the walls and floor slabs. Demolition material will be allowed to accumulate on the building slabs while it is segregated for disposal. Disposal will be based on the material type and intended disposition (salvaging, recycling, or landfill). A variety of salvage and recycling facilities exist within the Portland Metro area. Materials that are not feasible for re-use or recycling will be disposed of at a permitted solid waste landfill.

Concrete floor slab, walls, and footings are anticipated to be removed by an excavator with breaker attachment and/or by excavator bucket with thumb to remove large pieces. Dust control methods will be implemented to reduce particulate levels and will include wetting active demolition areas as required. Erosion and sediment control measures will be installed and will include silt fencing placed downgradient of all work areas.

Excavation of impacted soil is anticipated in the floor patch area, and potentially other areas of the Site such as the former wash pad near MW-1 (Figure 5). It is anticipated that from 10 to 100 cubic

DRAFT



yards of potentially-impacted soil will be excavated at the site. Excavated soils will be moved into a designated temporary stockpile area, and then directly loaded into trucks and transported off Site to the Waste Management Subtitle D landfill located in Hillsboro, Oregon. The truck haul route is shown on Figure 6. Removal activities will be observed by Amec Foster Wheeler.

The temporary stockpile area will be constructed with a base of 12-mil plastic sheeting wrapped around hay bales or straw wattles to create a berm surrounding the pile. The temporary stockpile will be covered with 12-mil plastic sheeting and weighted with sand bags when not actively in use. Only non-hazardous soil will be placed in the temporary stockpile.

5.5.1 Cultural Resources Monitoring During Soil Excavation Monitoring by an archeologist is required during soil excavation at this Site, and all subsurface activities (e.g. soil excavation, monitoring well installation) are subject to the Inadvertent Discovery Plan that has been prepared for this Site (Appendix F). If archaeological objects or sites are discovered during subsurface activities, then all activities should cease immediately until a professional archaeologist can evaluate the discovery. An archaeologist will be on Site to observe soil excavation. The General Contractor must notify Amec Foster Wheeler and the archeologist at least 24 hours prior to any soil excavation activities at the Site. If work is halted due to an inadvertent discovery, a 100 foot buffer area will be marked within which all work must cease until a determination regarding cultural significance is made by the archeologist. Work can, however, proceed outside of the 100-foot buffer. It is anticipated that soil excavation will be completed within a single day, and therefore only one day of archeologist monitoring will be required.

5.5.2 Excavation and Loading of Demolition Materials and Impacted Soil The Contractor will demolish, excavate, and load materials/soil using the following procedures:

• Excavation equipment and trucks must be in good working order. Equipment will be cleaned before arriving at the Site to allow inspection by the Contractor. Upon arrival the General Contractor will inspect each truck for leaks, and any repairs will be made prior to loading the vehicle. During the course of the project, the Contractor will immediately clean up any impacted soil resulting from spilled hydraulic oils or other hazardous materials from equipment. General Contractor will have absorbent pads available on Site for immediate use in the event of an equipment leak.

• Materials removed during the deconstruction and demolition activities will be segregated by intended end use/destination (e.g. recycling or disposal). Materials will be broken down into appropriate sizes by use of shears, breakers, and crushers, so that they can be fitted and loaded into trucks or roll-off containers. Stockpiling of debris will be avoided to the extent practicable, with preference for direct loading of demolition debris throughout the work day.

DRAFT



• Excavation of impacted soil (or potentially-impacted soil) in the floor patch area (or other areas on Site) will be conducted using an excavator or backhoe. The depth of the soil excavation will be determined by the Amec Foster Wheeler representative on Site, but is not expected to exceed six feet below ground surface (bgs). Soil will either be temporarily stockpiled on plastic, or directly loaded into the dump truck.

• Water will be sprayed over the excavation area as needed to suppress any generated dust.

• The truck(s) used to transport impacted soil will be equipped with bed liners and will drive through the access gate into the exclusion zone to be loaded. Truck loading will occur entirely within the designated loading zone. An excavator or loader will transfer soil to the haul truck(s) in a manner that prevents spilling, tracking or dispersal of impacted soil. For example, the excavator or loader bucket will not be filled to capacity when loading, any free liquid will be drained from the excavator or loader bucket prior to loading, and the excavator or loader bucket will be gently shaken over the excavation or temporary stockpile to prevent accidental spillage. All spilled material will be hand shoveled and placed immediately into the truck or temporary stockpile.

• Liquids accumulated within the bermed loading area will be controlled to prevent overflow and runoff. Accumulated liquids will be collected with a sump pump containerized in 55 gallon drums, and sampled for disposal characterization. The General Contractor will inspect each haul truck leaving the exclusion zone and broom clean loose soil, or pressure wash soil adhered to the truck exterior before they leave the loading area. The General Contractor will collect and return removed material to the excavator bucket for placement in the truck’s load or back onto the temporary soil stockpile.

• If soils are determined to be hazardous, then all trucks hauling hazardous waste will have the truck bed lined with 12-mil plastic sheeting prior to loading of the soil. Soil then will be covered with a tarp that is secured for transport.

• The Contractor will ensure that loaded truck weights are within acceptable limits and that the transporter has all necessary information for the disposal facility prior to leaving the Site.

5.5.3 Transportation and Disposal of Impacted Soil and Hazardous Building Materials The General Contractor will properly prepare bills of lading, or other related documents required by the solid waste treatment or disposal facility and submit all receipts of disposal or treatment to Amec Foster Wheeler or the CCDA (or City of Tigard Public Works Department) within 48 hours of shipping materials off Site. All trucks will follow a designated transportation route. The transportation route to the Waste Management Landfill in Hillsboro, Oregon, is presented in Figure 6. In the event of a highway closure or hazardous driving conditions along the haul route, trucks will be held at the Site within the staging area.

DRAFT



When transporting material off site, the General Contractor will comply with all applicable Federal, State, or local laws, codes, and ordinances that govern or regulate solid waste transportation. The General Contractor will ensure that all drivers hauling material have in their possession during hauling all applicable Oregon State and local vehicle insurance requirements, a valid driver's license, and vehicle registration and license documentation. The General Contractor will use end dump trucks to transport material that are substance compatible, licensed, insured, and permitted pursuant to federal, state, and local statutes, rules, regulations and ordinances. Drivers of haul vehicles transporting material off Site will be informed of:

• The nature of the material being hauled.

• The required routes to and from the designated loading area.

• The applicable City of Tigard street regulations and requirements, and State of Oregon Department of Transportation codes, regulations, and requirements.

• The legal maximum load limits per vehicle.

Prior to trucks leaving the Site, the General Contractor will decontaminate the equipment to prevent impacted soil from being spilled or tracked off Site. Decontamination will include broom cleaning or similar methods to remove all soil from the exterior of the truck. The loads of each truck will be covered with a well-secured tarp prior to trucks leaving the Site. Trucks will not be allowed off Site if free liquids are draining from the load. Haul trucks and roll-off containers will also need to be covered with a well-secured covering or tarp prior exiting the Site to prevent demolition debris and materials from falling onto the roadways.

Hazardous Building Materials that will be removed from the building prior to demolition activities include asbestos, fluorescent bulbs, ballasts, and smoke detectors. Asbestos containing materials will be bagged by the abatement workers and will be disposed of separately at Hillsboro Landfill. Fluorescent bulbs, ballasts, and smoke detectors will need to be carefully collected into an approved disposal container and disposed of at a Metro qualified disposal facility.

5.6 DISPOSAL PLAN

Building Materials that will not be re-used, salvaged, or recycled will be transported to the Waste Management Landfill located in Hillsboro, Oregon. Building materials that will be recycled or re-used (e.g. concrete, steel, metal, and timber) will be placed in roll-off containers to be picked up by the recycler or hauled directly to the contractor’s own facility. A variety of salvage and recycling facilities exist within the Portland Metro area and location will be dependent on demolition contractor selection and their preferred provider. Recycling receipts will be provided to Amec

DRAFT



Foster Wheeler and the CCDA (or City of Tigard Public Works Department). Impacted soils will be transported to the Waste Management Landfill located in Hillsboro, Oregon. Disposal receipts will be provided to Amec Foster Wheeler and the CCDA (or City of Tigard Public Works Department).

5.7 UNANTICIPATED OR UNKNOWN CONTAMINATED SOILS

Unanticipated or unknown contaminated soil may be encountered during RAP implementation. Unanticipated or unknown contaminated soil may be identified from the observation of unusual soil staining or odors, or the occurrence of oily liquids. If observed, Amec Foster Wheeler will direct the General Contractor to stop work. Amec Foster Wheeler will conduct screening of soil for volatile organic compound (VOC) vapor concentrations with a photoionization detector (PID). If a VOC vapor concentration in excess of 50 part per million (ppm) is measured, Amec Foster Wheeler will direct the General Contractor to stop work for 30 minutes to allow vapor concentrations in ambient air to reduce and make appropriate modifications to management procedures.

The Contractor will perform the following steps in the event that unanticipated or unknown contaminated soil is encountered during excavation indicated by the monitoring procedures described above:

• Upon discovery of suspected unanticipated or unknown contaminated soil, immediately suspend all activities in the vicinity and notify Amec Foster Wheeler.

• Upon notification, Amec Foster Wheeler will evaluate whether unanticipated or unknown contaminated soil has been encountered. Amec Foster Wheeler may collect and analyze samples to make this determination.

• Suspected unanticipated or unknown contaminated soils will be segregated and managed separately from other excavated material.

In the event that Amec Foster Wheeler determines that potentially unanticipated or unknown contaminated soil has been encountered, the General Contractor will perform or comply with the following:

• Secure the area as necessary to restrict and protect workers and the public from exposure to unanticipated or unknown waste.

• Modify the health and safety plan, including designation of an exclusion zone for the area where the potentially unanticipated and unknown contaminated soil has been encountered. Amec Foster Wheeler will provide unanticipated or unknown contaminated soil sampling and analysis results to assist in making appropriate document modifications.

DRAFT



• Once directed by Amec Foster Wheeler, the General Contractor will perform all excavation, temporary storage, management, loading, hauling, and disposal of unanticipated or unknown contaminated soil. Temporary storage will involve creating a soil stockpile within a bermed liner and covered by plastic sheeting weighted with sand bags. Amec Foster Wheeler will direct the General Contractor in the disposal of the unanticipated or unknown contaminated soil. If the contaminated soil is determined to be a hazardous waste, it will be removed and disposed of within 30 days of initial excavation.

• If the General Contractor encounters an underground storage tank(s) (UST[s]), they will immediately inform Amec Foster Wheeler, and with assistance from Amec Foster Wheeler, will manage the UST(s) according to Oregon Administrative Rules (OAR) 340-122.

5.8 RECORD KEEPING

The General Contractor will be required to provide documentation describing all activities related to the excavation, onsite management, transportation, and disposal of materials and soil generated during Site cleanup activities.

Daily field reports will be prepared by Amec Foster Wheeler each day during RAP implementation and will: 1) document location of pre-demolition, demolition and/or deconstruction activities, structures and materials removed, and any disposal and recycling with an estimate of volume by material type; 2) document erosion and sediment control observations including dust mitigation measures; 3) list any safety deficiencies, including traffic control plan implementation issues; 4) document all excavation and management of soil, including locations and depths where contaminated soil was excavated; 5) describe volume of soil placed in, or removed from, soil stockpiles; 6) describe the location, depth, and nature of any unanticipated and unknown contaminated soil encountered or observed and the response taken; and 7) describe any confirmation or profile sample collection.

6.0 CLEANUP CONFIRMATION SAMPLING

Amec Foster Wheeler will visually observe soil conditions during excavation activities to assist in identification of impacted versus non-impacted soils, and to determine when impacted soils have been sufficiently removed. Confirmation sampling will be performed either using a hand auger or by collecting material directly from the excavator (or backhoe) bucket. Details of the sampling procedure is provided in the SAP and QAPP.

DRAFT



7.0 EXCAVATION BACKFILLING

The soil excavation area(s) and removed building footings areas will be backfilled using structural fill as specified in the “Report of Geotechnical Engineering Services” (GeoDesign, 2016). In particular, Section 5.6.1.3 of the report discusses materials for structural fill. The specifications include requirements that: “Imported granular material used as structural fill (Section) should be pit- or quarry-run rock, crushed rock, or crushed gravel and sand and should meet the specifications provided in [Oregon Standards Specifications for Construction] OSSC section 00330.14 (Selected Granular backfill) or OSSC section 00330.15 (Selected Stone backfill)”. Imported granular material will be placed in lifts with a maximum thickness of 12 inches and compacted to 95 percent of the maximum dry density as determined by ASTM D 1557.

8.0 SOIL GAS SAMPLING

Amec Foster Wheeler will collect five soil-gas samples from the Site. The samples will be collected after the building demolition/removal is complete. The five proposed sampling locations (VP-1, VP-2, VP-3, VP-4, and VP-5) span the area of the proposed future building footprint, and are presented on Figure 2. The purpose of the soil-gas sampling will be to supplement earlier soil-gas data, and allow DEQ to make a determination as to whether a passive vapor barrier will be required to protect future building occupants. Details of the soil-gas sampling procedure are provided in the SAP and QAPP.

9.0 PASSIVE VAPOR BARRIER INSTALLATION

Based on the results of the soil cleanup and additional testing (soil, soil gas, and groundwater), a determination will be made by DEQ as to whether or not a passive vapor barrier will be required at the Site. If a passive vapor barrier is required, then Amec Foster Wheeler will design the barrier in accordance with applicable standards, and in a manner compatible with the design of the proposed building. The vapor barrier will include a heavy duty plastic liner and sub-slab passive ventilation system (slotted pipe screens set within gravel trenches), all of which will be placed directly beneath the concrete slab of the building. The piping system will manifold together above grade and will be routed to the building’s roof to vent. The passive vapor mitigation system will provide a preferential pathway that directs impacted soil gas (vapors) around and away from the building, and could be enhanced by installing a solar powered low-power fan to maintain a minimal negative pressure gradient in the system.

DRAFT



10.0 MONITORED NATURAL ATTENUATION

Monitoring wells MW-1, MW-2, MW-3, and MW-4 will be installed and used in the MNA program (Figure 2). Each monitoring well shall be constructed of 1.5-inch inner diameter Schedule 40 polyvinyl chloride (PVC) casing and 1.5-inch inner diameter Schedule 40 PVC 0.010-inch slotted pre-pack well screen (Appendix E). Each monitoring well will be completed to a total depth of approximately 18 feet bgs with a 10 foot screen interval (from 8 to 18 feet bgs). A filter pack (pre-pack) consisting of 10/20 silica sand shall be placed around the slotted well screen, and extend a minimum distance of 0.5 foot above the top of the well screen. The remaining annular space of the wells will then be filled with hydrated bentonite grout or with bentonite chips as appropriate up to a depth of 1.5 feet bgs. The upper 1.5 feet bgs to the ground surface shall be completed with a concrete seal. Each well shall be completed to existing ground surface with a traffic-rated monument.

The MNA sampling results would be assessed to evaluate remedial progress and the predicted time for cleanup to be complete. As soon as MNA trends indicate that the plume is stable/shrinking, site closure would be sought. If trends toward closure are slow to develop, then an annual MNA monitoring frequency would be requested. The length of MNA is estimated at one year.

11.0 REMEDIAL ACTION REPORT

At the conclusion of the initial RAP cleanup activities, and following receipt of laboratory analytical results for the excavation closure sampling and the first round of MNA well sampling, Amec Foster Wheeler will complete a cleanup report. This written report will be provided to the CCDA, DEQ, and EPA, and will include the following:

• Boring logs;

• Depth to groundwater and well survey information;

• Analytical data reports;

• Discussion of deviations from the procedures described in the SAP or QAPP;

• Summary of soil, soil gas, and groundwater analytical results;

• Summary of all Site data (and pertinent adjacent property data) collected to date;

• Comparison of contaminant data to RBCs (DEQ, 2015);

• A full evaluation of Site risk, including the extent of contamination at the Site; and

• Recommendations for additional investigations and/or remedial actions, as appropriate.

DRAFT



A second (final) report will be prepared after the conclusion of the remaining three quarters of MNA sampling. The final report will include the items listed above as well as a discussion on overall cleanup trends for the Site, and a request for an NFA finding (if appropriate). A draft of this final report will be submitted to the EPA and DEQ within 45 days of completion of the third quarter of MNA sampling activities.

12.0 COMMUNICATION PLAN

A copy of this Remedial Action Plan will be posted on the City of Tigard’s website and a copy will be available at the City Public Library.

APPENDIX A

Fact Sheet: Main Street at Fanno Creek Cleanup

About the Sites The Main Street at Fanno Creek properties at 12533-12537 SW Main Street have historically been the site of a variety of businesses and activities dating back to at least the 1930s. These included a planing mill, tire, welding, printing, and automotive repair shops. Testing shows that these past uses resulted in releases of petroleum and solvents into the soil and groundwater beneath the Sites.

Environmental AssessmentSubsurface samples (soil, soil gas, sediment, and groundwater) were collected from the Main Street at Fanno Creek sites in 2012, 2013, and 2014.

Results:

• Soil - within DEQ limits.

• Soil Gas - within DEQ limits.

• Sediment - low-levels of petroleum and hazardous substances(polynuclear aromatic hydrocarbons (PAHs), polychlorinatedbiphenyls (PCBs), and metals.)

• Groundwater – Moderate level of hazardous substances(halogenated volatile organic compounds (HVOCs)) in upland area.

Minor impacts to soil, soil gas, and sediment do not pose a risk to human health. Impacts to groundwater from the hazardous substances (HVOCs) may pose a pose a risk to any future residents of the site, if not controlled.

Brownfields Cleanup GrantThe City Center Development Agency of the City of Tigard (CCDA), Tigard’s urban renewal agency, was awarded two Brownfield Cleanup Grants totaling $400,000 by the US Environmental Protection Agency (EPA) in 2016 for the sites. The grant funding allows the CCDA to remove the buildings, clean up potentially-impacted soil, monitor contaminants in groundwater, and mitigate contaminants in soil gas.

FACT SHEET | April 2017

Main Street at Fanno Creek Brownfield Cleanup

Concept for the new Main Street at Fanno Creek mixed-use development and public space.

Vacant building overhanging Main Street at Fanno Creek Brownfield site.

Proposed Environmental Cleanup Activities: 1. Building demolition.

2. Removing regulated building materials and potentialcontaminated soil to Hillsboro Landfill.

3. Installing a passive vapor barrier, if needed, beneath a futurebuilding footprint (barrier would consist of a sheet of plasticunderlain by piping trenches to collect vapors).

4. Installation and sampling of four groundwater monitoringwells as part of a monitored natural attenuation (MNA)program. (Monitored natural attenuation relies on naturalprocesses to decrease concentrations of contaminants in soiland groundwater. Scientists monitor these conditions to makesure natural attenuation is working at a reasonable pace andthat the area of contamination is shrinking over time.)

Proposed Schedule:

The building and soil removal, is scheduled to begin in June, 2017, and is expected to take four to six weeks. It should result in minimal disturbance to pedestrians, traffic, and parking areas along SW Main Street.

The installation of a passive vapor barrier may or may not be necessary, and will be determined by the Oregon Department of Environmental Quality (DEQ) depending on the results of additional soil, soil gas, and groundwater testing. This additional testing will be completed after the buildings have been removed. Any vapor barrier would be installed concurrent with construction of the future building/structure.

The monitoring wells will be installed as Site conditions allow (date to be determined following building and soil removal activities), with all well installations completed by Fall 2017. The drilling activity for the well installations will be similar to what occurred at the Site in 2012, 2013, and 2014. No effect on vehicle or pedestrian traffic is anticipated for the well installations or subsequent well sampling. Drilling will be completed on a single day. Development and initial sampling of the wells will occur approximately three days following installation, and will require one or two days to complete. Subsequent rounds of sampling will occur at approximately three month intervals for one year, with each sampling event taking approximately one day.

Main Street at Fanno Creek Brownfield Cleanup

This fact sheet was developed under Assistant Agreement No. 01J23901 awarded by the U.S. Environmental Protection Agency. It has not been formally reviewed by EPA. The views expressed are solely those of the City Center Development Agency of the City of Tigard, and EPA does not endorse any products or commercial services mentioned.

What are Brownfields?A brownfield is land that is vacant or underused because of the actual or perceived presence of a hazardous substance or contaminant.

Some brownfield sites are actively being used while pollutants remain in the soil or groundwater; the contamination can become an issue when property owners want to expand, redevelop or sell their land.

Cleaning up and reinvesting in Brownfields protects the environment, reduces blight, and can help bring new jobs to communities.

Nearest Water: Carry water; in Tigard Cleaners and Kepler’s Upholstery building.

Location of First Aid Kit: In vehicle.

POTENTIAL PHYSICAL HAZARDS: Includes but not limited to: back injuries, biological agents, heat stress, falling objects, electrocution, entanglement, drowning, excavation around subsurface utilities (e.g., electrical, natural gas, sewer and water lines), fire and explosion, heavy equipment and vehicles, inclement weather and shut-down conditions, noise, slips, trips, and falls, UV exposure.

CONTAMINANTS OF POTENTIAL CONCERN (COPCs): Based on the results of numerous Phase I and Phase II ESAs, Amec Foster Wheeler concludes that recognized environmental conditions (RECs) associated with the adjoining properties (Site) can be summarized as follows:

Documented releases of halogenated volatile organic compounds (HVOCs) from a former automobile service facility and current dry cleaner business have affected soil and groundwater beneath the Site. In addition, petroleum hydrocarbons and heavy metals have been detected in sediments along the bank of Fanno Creek.

HVOCs (particularly tetrachloroethene [PCE] and trichloroethene [TCE] have been detected in sub-slab soil gas that exceed the urban residential and occupational risk based concentrations (RBCs) for vapor intrusion into buildings at several locations at the Site. Concentrations of vinyl

chloride also exceed the urban residential RBC for vapor intrusion into buildings in a ground water sample collected from the center of the Site. Finally, a few heavy metals and Polynuclear aromatic hydrocarbons (PAHs) have been detected in Fanno Creek sediments at concentrations slightly above urban residential RBCs. Chemical hazard properties and exposure information for most of these chemicals can be found with the SDS in Appendix 5, and all can be accessed online.

3.2.1.1 Barriers and Signs: Caution tape will be placed at a safe distance from bore holes. Signs will be conspicuously posted as the following, or equivalent:

“CONSTRUCTION AREA - Authorized Personnel Only”

3.2.2 Rinsate Collection/Containment

A system for collection of rinsate from decontamination operations (e.g., vacuum truck, heavy equipment, personnel decontamination, etc.) will be necessary for the Site. The system will be as complex or simple as necessary to collect and contain spent decontamination fluids, including overspray from cleaning operations.

If necessary, construction of “permanent” or “temporary” stations for heavy equipment decontamination, and areas where cleaning of equipment (e.g., augers, spoons, etc.) or personal decontamination occurs will be the responsibility of the SHSC and Project Manager.

3.2.3 Noise Reduction

Site activities in proximity to construction and heavy equipment often expose workers to excessive noise. It is anticipated that situations will arise when noise levels may exceed the OSHA Action Level of 85 decibels (A-weighted scale [dBA]) in an 8-hour time-weighted average (TWA). Hearing protection will be required when working near the drill rig.

3.3 PERSONAL PROTECTIVE EQUIPMENT

3.3.1 Levels of Protection

Initial levels of personal protective equipment (PPE) for construction workers at the Site is Level D. These workers will be required to wear the U.S. Environmental Protection Agency (EPA)/OSHA Level of Protection as specified in Appendix 6. Protection may be upgraded or downgraded depending upon Site conditions (compared with action levels), as determined by the SHSC.

The following outlines the minimum guidelines for each level of protection that is assigned or potentially assigned. If Site conditions warrant higher levels of personal protection, the personnel should stop all work activities and notify the SHSC or Site Superintendent.

DRAFT



3.3.1.1 Level D PPE: • Work shirt and full-length pants or coveralls

• Closed-toed leather work boots or American National Standards Institute (ANSI) safety work boots (as appropriate with task activity safety level)

• Enter the Support Zone (SZ).

3.3.3 PPE Failure/Chemical Exposure

In the event of PPE failure, worker and/or buddy will cease work, and perform personal decontamination procedures. If chemicals contact the eyes, irrigate for 15 minutes and consult a physician.

3.3.4 PPE Inspection, Storage, and Maintenance

Reusable PPE will be decontaminated, inspected, and maintained, as necessary, after each use. Personal equipment (e.g., safety glasses, leather safety-toe boots) shall be properly stored by the employee/subcontractor.

The SHSC will periodically inventory the disposable and reusable PPE at the Site and will replenish stocks in a timely manner.

4.0 PROJECT AREA CONTROL

4.1 SITE SECURITY

Access will be limited to all controlled areas via the prescribed administrative (certifications) and engineering (barricades) controls. All Site staff and visitors will note arrival and departure times on a field log by SHSC. All equipment, tools, and property shall be secured at the end of each day.

4.2 VISITOR ACCESS

All Site visitors must receive prior approval from the SHSC, Project Manager, and/or Client, and may do so only for the purposes of observing Site conditions or operations. All visitors, regardless

DRAFT



of their rank or professional level, will not be allowed into controlled work areas unless training requirements have been met and documented.

4.3 WORK AREAS AND ZONES

Work zones typically are categorized into the following three zones. Support Zone (SZ), Contamination Reduction Zone (CRZ), and Exclusion Zone (EZ).

4.3.1.1 Support Zone (SZ): The SZ will consist of the staging area at the Site (TBD, pending Site assessment prior to commencement of project). Vehicles, emergency equipment, equipment trailers, break area, and any nonessential personnel will be located in this area.

4.3.1.2 Contaminate Reduction Zone (CRZ): A decontamination staging area will be established for personnel and equipment between the Site work area and the Support Zone to minimize the amount of soil being carried off the Site.

4.3.1.3 Exclusion Zone (EZ): The EZ is defined as the area immediately around the drill rig or excavation area. Access should be restricted to appropriately trained crews and necessary equipment operators.

4.4 COMMUNICATIONS

A universal system of hand and horn signals will be used:

Thumbs up = OK; understand

Thumbs down = No; negative

Grasping buddy’s wrist = Leave Project Area now

Hands on top of head = Need assistance

Horn - one long blast = Evacuate Project Area

Horn - two short blasts = All clear, return to Project Area

5.0 AIR SURVEILLANCE

5.1 TYPE AND FREQUENCY OF MONITORING

If significant subsurface activities are performed (e.g., well installation), Amec Foster Wheeler personnel will conduct air monitoring using a PID when HVOC or petroleum-like odors are

DRAFT



encountered and soils need to be further characterized. Dust monitoring will be performed, using an aerosol monitor if visible dust cannot be controlled through work practices, such as, wetting of soils.

Type Minimum Recommended Monitoring Frequency*

Background: As needed, once per day in the work area and perimeter using direct-reading instruments, prior to any intrusive or dust producing activities and equipment startup.

Perimeter: As needed, at least twice per day using direct-reading instruments during intrusive activities

Personnel: At least twice per day in the breathing zone (BZ) of those with the highest anticipated exposure during intrusive or dust producing activities where visible dust cannot be controlled through work practices.

Area: At least twice per day in each work zone and at the onset of any new intrusive or dust producing activities, or at new locations when monitoring is necessary.

*When contaminated media is encountered or anticipated (not required for subslab vapor or indoor air sampling)

5.2 MONITORING INSTRUMENTS

The SHSC will maintain information for instruments, including specifying calibration, general use, and troubleshooting procedures. All monitoring equipment will be field calibrated on a daily basis according to the manufacturer’s instructions and will be recorded on the field notebook.

Equipment Contaminant Work Activity

PID Petroleum hydrocarbons and HVOCs As needed if petroleum odors encountered.

5.3 ACTION LEVELS

Action levels and visual criteria have been established for work stoppages, and evacuation (see Appendix 6 for Justification of Action Levels). The decision to stop work must be based upon instrument readings measured in the BZ of Site personnel and comparison of the results to the information contained in HASP Summary Information Sheet. Record readings in the field notebook. See Section 2.1 related to visual work stoppage criteria.

DRAFT



5.4 NIOSH/OSHA AIR SAMPLING METHODS

If needed, worker exposure monitoring may be performed to determine the exposure to specific COPC. The exposure monitoring will be performed using NIOSH or OSHA methods and compared to specific OR-OSHA permissible exposure limits (PEL) or American Conference of Governmental Industrial Hygienist (ACGIH®) Threshold Limit Values (TLVs®). Where there are differences between PEL and TLV® values, the most stringent shall be used to assess risk.

6.0 DECONTAMINATION

The procedures outlined below shall be employed where applicable during decontamination of field equipment. Note that separate areas should be established for personnel and heavy equipment decontamination; see also Section 3.2 (Engineering Controls) of this HASP.

6.1 DECONTAMINATION STAGING AREAS

Decontamination staging areas for equipment and personnel decontamination will be established as appropriate. The staging area(s) shall be selected based on the ability to control access to the area, control residual material removed from equipment, store clean equipment, and access to the activity area.

6.2 FREQUENCY OF DECONTAMINATION

All equipment shall be free of dirt, mud, and debris prior to coming inside the project area. Additionally, all equipment (including heavy equipment if utilized) and power tools will be decontaminated prior to leaving the Site when contaminated media is encountered, to prevent soil and dirt from leaving the Site. Personnel will decontaminate upon completion of their work shift or after the task at hand in the case heavily soiled conditions or failure of PPE.

6.4 EQUIPMENT DECONTAMINATION

Equipment in direct contact with contaminated soil or groundwater shall be washed and inspected by the SHSC prior to leaving the Site.

6.5 EMERGENCY DECONTAMINATION

In the event of an accident or incident where work must cease and staff must exit the EZ, emergency decontamination should be performed to the greatest extent feasible. In an emergency, the primary concern is to prevent the loss of life or severe injury. If immediate medical attention is required to save a life, decontamination should be delayed until the victim is stabilized. If the decontamination can be performed without interfering with essential life-saving techniques or first aid, or if a worker has been contaminated with an extremely toxic or corrosive material that could cause severe illness or loss of life, decontamination must be performed immediately. If an emergency due to a heat-related illness develops, protective equipment should be removed carefully from the victim as soon as possible.

6.6 WASTE DISPOSAL PROCEDURES

All discarded materials that accumulate from Site activities (e.g., PPE, wash water, supplies, etc.) will be segregated by matrix and disposed of properly.

DRAFT



7.0 SANITATION AND ILLUMINATION

7.1 SANITATION AND PERSONAL HYGIENE

Potable drinking water shall be supplied in tightly-closed containers and shall be clearly marked for its intended use. If vehicles are available for use by field crews, restrooms and a field washing area with potable water will be available within a reasonable distance from the Site. If such facilities are not located within a reasonable distance, portable facilities will be installed for use by field employees.

Facilities will be available for workers to wash their hands and face (as necessary) immediately prior to any work or lunch break or prior to eating, drinking, smoking, or when exiting the Site.

7.2 ILLUMINATION

Lighting is present in the Tigard Cleaners and Kepler’s Upholstery building. Street lighting is present along SW Main Street. If work is conducted after dark then additional portable lighting may be necessary.

8.0 SPILL PREVENTION

Fuels and other hazardous materials brought on to the Site will be limited in quantity. No on-Site storage is anticipated. Drip pans and absorbent socks will be used to ensure that no fuels are spilled during fueling activities.

9.0 EMERGENCY ACTIONS

9.1 PREPLANNING AND GENERAL PROCEDURES

9.1.1.1 General Emergency Information: Site personnel should be constantly alert to recognize potentially unsafe work practices, hazardous work environments, and conditions that are immediately dangerous to life or health (IDLH), and they should be routinely reminded of signs and symptoms of chemical and heat overexposure. Prearrange access for emergency crews when necessary.

In the event of a large-scale spill, fire/explosion, or major emergency, the SHSC is expected to notify the Client, evacuate the area, and let appropriately-trained emergency staff respond to the situation. The safety and well-being of project personnel, visitors, and the adjacent community will be of utmost importance in determining the appropriate response to a given emergency.

DRAFT



9.1.1.2 Emergency Coordinator (EC): The SHSC will serve as the Emergency Coordinator (EC) during an actual emergency response situation. The SHSC will serve as the primary EC at all times. The EC will contact off-Site emergency response agencies and will serve as the main spokesperson when the responders arrive at the Site.

9.1.1.3 Project Area Maps: An updated Site map that is used during daily tailgate meetings will be used to inform the staff of hazardous areas, zone boundaries, Site terrain, evacuation routes, work crew locations, and any Site changes. In the unlikely event that an emergency occurs, the problem areas will be pinpointed on the Site Map, and pertinent information, such as weather and wind direction, temperature, and forecast, will be added as obtained. This map will be provided to the responding agencies.

9.1.1.4 Emergency Decontamination: For first aid of non-life-threatening injuries, evacuate to decontamination line and decontaminate as much as possible or practical; contaminated clothing should be removed. For life-threatening injuries/exposures, field decontaminate as much as possible for the person’s own safety, wrap in a blanket or polyethylene sheeting, and immediately transport to the designated medical facility. Also, phone ahead and bring this HASP for informational purposes and SDS access by medical staff.

9.1.1.5 Safe Refuge Area: To be determined; this will be discussed in the tailgate meetings by the SHSC once at the Site. It will be set up in the SZ or at an off-Site location in the event of a Site-wide evacuation. This area will be upwind, and the location and escape routes will be designated on Site control maps. In an emergency, the EC will take a “head count” against the field notebook, initiate search/account for missing persons, notify the emergency crews (as applicable), and limit access into the hazardous emergency area to necessary rescue and response personnel in order to prevent additional injuries and possible exposures.

9.1.1.6 Emergency Equipment: Emergency equipment will be maintained in the construction trailer (CT) or field vehicle (V), in the SZ, with the exception of items marked by an asterisk that will be kept in the restricted work zone (RWZ). All items must be checked and maintained by the SHSC at least weekly and after each use.

DRAFT

Spill Equipment, V/CT Mobile Phone, V/CT

Eyewash station*, CT/RWZ Hospital Route Map, V/CT

9.1.1.7 Evacuation Procedures: Expeditious evacuation routes to the Safe Refuge Area(s) will be established daily for all work area locations, with respect to the wind direction. Evacuation notification will be a continuous blast on a canned siren, vehicle horn, or direct verbal communication. Emergency drills should be performed periodically. Any additions to evacuation procedures require an update to this HASP.

In the unlikely event that an evacuation is necessary, all personnel will immediately proceed to the predetermined Safe Refuge Area, decontaminating to the extent possible for personal safety, based on the emergency. The EC should then begin the Site security and control measures.

9.2 SITE-SPECIFIC RESPONSE SCENARIOS

9.2.1 Natural Disasters

9.2.1.1 Earthquake Alarm: Car Horn

Action: Cease operations and turn off equipment. Seek protection under a sturdy table or stay in the open. Inspect area and equipment prior to starting work again.

9.2.2 Weather-Related Emergencies

All work will cease should any of the following weather conditions arise:

• Precipitation severe enough to impair safe movement/travel

• Flooding

• Other conditions as determined by the SHSC, Project Engineer, or Project Superintendent

9.2.3 Spill and/or Discharge of Hazardous Materials

9.2.3.1 Training: Responses to incidental releases or spills of hazardous substances that can be absorbed, neutralized, or otherwise controlled at the time of release by employees in the immediate release area are not considered to be emergency responses under 29 CFR 1910.120(l) and do not require additional specialized training.

DRAFT



9.2.3.2 Spill Control and Response: There is a potential for incidental spillage/leakage of hazardous materials (fuels, grouts, detergents, etc.) that are brought onto the Site to implement project activities. Store these materials properly and maintain the appropriate spill response equipment in or easily accessible to the area where the materials are used/stored. In case of incidental spills or leaks, follow these steps:

1. Notify the SHSC and Project Superintendent

2. Select appropriate PPE and response equipment

3. Contain the spill to the extent possible

4. Neutralize or solidify the liquid per the MSDS

5. Transfer to an IDW container

6. Document

7. Notify the Client

9.3 MEDICAL EMERGENCY RESPONSE

Provided at the start of this document.

9.3.1.1 Site Personnel Response Actions: Call the SHSC, who will assess the situation, first taking necessary precautions for personal safety. The EC will follow The Emergency Medical Plan outlined in the Safety Policy Manual and determine whether to summon an ambulance by calling 911. The Site control measures will be implemented by the EC. Any off-Site responding agencies will be given the Site Map and informed about the Site-specific hazards so they can be optimally helpful in an emergency situation.

In emergencies, the injuries and illnesses that may arise will vary from incident to incident; check Appendices 1 and 2 and the SDSs (Appendix 5) or contact the Poison Control Center for emergency first aid procedures. Any first aid treatment is considered a Good Samaritan Act. It is essential that all Site personnel in need of emergency care receive treatment

9.4 ACCIDENT REPORTING AND RECORD KEEPING

At the onset of an employee work-related injury or illness all employees and subcontractors should notify the SHSC. The employee is required to report all work-related injuries; plus all non-work related injuries that may affect his/her ability to safely perform their job.

DRAFT



The SHSC will conduct an investigation in accordance with safety policies. Completed report(s) must be transmitted to the Corporate Safety Director within 24 hours of an occurrence; a fax is acceptable. Amec Foster Wheeler will complete Worker’s Compensation Insurance notifications, and conduct further incident investigation and develop internal communications if necessary.

Any release of information in these reports to unauthorized persons or agencies is prohibited unless it is first approved by the Client. Certain agencies or persons, such as OSHA or OSHA inspectors, can request this information and its release will be permitted. Review the Emergency Call List for additional contact names and phone numbers.

APPENDIX 3

Physical and Operating Hazards

DRAFT

Appendix 3



Back Injuries Due to Improper Lifting

Preventive Measures

♦ Use proper lifting techniques.

♦ Lift with the legs, not the back.

♦ Keep loads close to the body and avoid twisting.

♦ Loads heavier than 50 pounds (lbs) require a second person or mechanical device

for lifting.

♦ Use mechanical devices such as drum dollies, hand trucks, and tool hoists (for lifting

augers) to lift or move heavy loads whenever possible.

DRAFT

Appendix 3



Biological Agents

Preventive Measures

♦ Project work will not expose workers to infectious agents or wastes; however,

responders to first aid incidents could contact bloodborne pathogens. Follow the

Bloodborne Pathogen Control Plan in this Health and Safety Plan (HSP).¨

♦ Identify personnel who are highly sensitive or allergic to insect bites or stings during

the “kickoff” meeting so that the appropriate emergency treatment can be made

available on-site.

♦ Never try to capture wild or semi-wild animals—they may bite you or infect you with

parasites.

Poison Ivy, Oak, and Sumac

♦ Review the Poison Ivy, Oak, and Sumac Field Guide during daily tailgate safety

meetings. Worker must be familiar with the appearance of these poisonous plants.

♦ If there is accidental contact, carefully remove affected clothing and wash skin with

soap and warm water as soon as possible.

Ticks

♦ Tick parasites are commonly encountered in thick vegetation.

○ Check yourself and coworkers regularly for feeding ticks.

○ If a tick is located, remove it with tweezers and place in a vial.

○ If irritation is felt or observed at the bite site, seek medical attention.

Bring in removed tick, if possible.

Hanta Virus

♦ In areas with rodent infestation, the existence of Hanta virus must be discussed

during the tailgate safety meetings.

♦ Hanta virus is carried by rodents, particularly deer mice. Exposure to the virus

through contact with the rodents and their droppings can lead to a severe, often

deadly illness in humans.

♦ Do not sweep up or disturb rodent droppings without an appropriate respirator.

♦ Do not eat food or drink beverages that have been exposed to rodents and/or their

droppings.

DRAFT

Appendix 3



Biological Agents (Continued)

Preventive Measures

Valley Fever

♦ In parts of the California Central Valley and in other regions of the southwestern

United States, there are fungal spores in the soil, which, if inhaled, can cause an

illness known as Valley Fever (Coccidioidomycosis).

♦ During projects in areas of the country where Valley Fever fungal spores are known

or suspected to be in the soil, the hazards and symptoms must be discussed during

the tailgate safety meetings.

♦ Inhalation of dust containing the spores can cause the Valley Fever illness, which

has a wide range of symptoms. Symptoms can be mild, similar to the flu lasting a

few days, to more serious involving damage to the lungs, heart, and central nervous

system.

♦ In areas where the Valley Fever spores are known, dust suppression techniques are

critical to minimize exposure. Tarping and wetting down disturbed areas of soil will

help to control exposure. In the event these techniques are not feasible or effective,

air purifying respirators with P-100 filters shall be worn.

DRAFT

Appendix 3



Cold Stress

Preventive Measures

During tailgate safety meetings, train workers to recognize the signs and symptoms of

cold stress illnesses:

♦ Frostbite - Skin color changes to white to reddish, pain followed by cold and

numbness in the affected area(s); blisters may appear later.

♦ Hypothermia - Uncontrollable shivering, a sensation of feeling cold, a slowed and

sometimes irregular heartbeat, a weakened pulse, and changes in blood pressure.

More severe cases can result in slurred speech, memory lapses, incoherence, and

drowsiness.

First Aid

♦ Frostbite - Cover the frozen body part, provide extra clothing and blankets, bring the

victim indoors as soon as possible, place the frozen body part in warm water

(~100°F) or re-warm with warm packs. Seek medical assistance as soon as

possible.

♦ Hypothermia - Get victim out of wind, snow, and rain. Keep person awake. Remove

any wet clothing and replace with dry, warm clothing. Wrap blanket around victim. If

conscious, give victim sweet warm beverages. Seek medical attention as soon as

possible.

Prevention

♦ Provide shelter away from rain, snow, or wind for breaks.

♦ Institute a work-rest schedule in accordance with the standard operating procedure

(SOP).

♦ Increase fluid intake to prevent dehydration. Drink warm, sweet, caffeine-free,

nonalcoholic drinks or soup periodically.

DRAFT

Appendix 3



Discharge of Static Electricity

(UST related)

Preventive Measures

♦ Properly ground and bond all equipment.

♦ Check for and remove ungrounded and unbounded objects in the tank, such as

loose gauge floats and sample can.

♦ Avoid splash filling. Discharge through the fill-pipe outlet near the bottom of the tank

with minimal agitation of the water and sediment (sludge).

♦ Avoid discharging fuel product from a nozzle that is elevated above the liquid level.

♦ Limit the velocity of the incoming liquid stream to 3 feet per second (ft/sec) until the

fill pipe is submerged either 2 pipe diameters or 2 ft, whichever is less.

♦ Avoid pumping substantial amounts of air or other entrained gas into the tank

through the liquid.

♦ Delay 1 minute or more before gauging, strapping, or sampling of static-

accumulating fuels after filling.

DRAFT

Appendix 3



Drill Rigs and Heavy Equipment Operation

Preventive Measures

♦ Owner/operator shall inspect equipment daily.

♦ Correct all discrepancies before placing equipment in service.

♦ Keep blades, buckets, and other heavy equipment fully lowered when not in use.

♦ Parking brakes must be engaged.

♦ After working hours, bucket may be elevated if the locking pin is in place.

♦ Never leave drill rods or core barrels balancing, leaning, or otherwise unsecured on

the rig.

♦ Chock or block the wheels of equipment parked on inclines. Set the parking brake.

♦ Never use equipment on unstable or unsafe inclines.

♦ Use hand signals, radios (as appropriate), and line-of-sight confirmation to

communicate effectively with operators.

DRAFT

Appendix 3



Electrocution

Preventive Measures

♦ Locate all underground power lines by geophysical methods.

♦ Review engineering drawings with appropriate client contact and/or site personnel.

♦ Confirm exact location of lines with hand tools, not heavy equipment.

♦ Wear rubber, insulated protective gloves when hand digging or work on a rubber

insulating mat.

♦ Do not work within 10 feet (ft) of high voltage electrical equipment having live

exposed parts unless qualified, trained, and following safe work practices per

29 CFR 1910.331-335.

♦ Leave at least 20 ft between drilling masts and overhead power lines under

50 kilovolts, unless the lines have been de-energized and visibly grounded at the

point of work, or are equipped with insulated barriers to prevent physical contact.

♦ Lower the drilling mast before moving the rig any distance.

♦ Lock-out and tag controls that will be deactivated for maintenance or work on

energized or de-energized equipment or circuits.

♦ Extension cords, power/electric tools, pumps, floodlights, and generators that lack

double insulation must have grounding conductors that work.

♦ Use ground fault circuit interrupters (GFCIs) on all 120-volt, 120-amp circuits.

♦ Never work on-site when there is a threat of lightning storms.

DRAFT

Appendix 3



Entanglement in Rotating or Moving Equipment

Preventive Measures

♦ Never operate equipment without safety guards.

♦ Loose-fitting or dangling clothes, hair, and jewelry are prohibited.

♦ Stay clear of rotating augers and pinch points, such as cables and pulleys.

♦ Passage under, or stopping over, a moving stem or auger is prohibited.

♦ Drill crews are not allowed on the mast while the drill bit/auger is in operation or

during transport.

♦ Use long-handled shovels only to remove cuttings from the auger.

♦ The drill crew and the Field Manager (FM)/Site Health and Safety Coordinator

(SHSC) will know the location and proper operation of the rig’s emergency shut-

down equipment (kill-switches, etc.), and procedures.

DRAFT

Appendix 3



Ergonomic Stress

Preventive Measures

♦ Lift carefully with load close to body with the legs taking most of the weight.

♦ Get help with lifts greater than 40 lbs.

♦ When working with a heavy tool or object, keep legs under the load and do not

overreach or twist to the side.

♦ Reposition body to be square to the load and work.

♦ Push loads, rather than pull, whenever feasible.

♦ Do not persist with lifting when the load is too heavy.

♦ Use a mechanical lifting aid or have a coworker assist with the lift.

♦ Rotate repetitive tasks to avoid soft-tissue fatigue.

DRAFT

Appendix 3



Falls from Elevated Surfaces

Preventive Measures

♦ Protect employees from falling off surfaces that have a side or an edge that is 6 ft or

more above a lower level.

♦ Provide a safety harness and shock-absorbing lifeline or adequate fall protection.

Employees must wear them when working 6 ft or higher above the platform or main

work deck.

♦ Install either a guardrail system or fall arrest system that conforms to 29 CFR

1926.502 (d) and is approved by the American National Standards Institute.

DRAFT

Appendix 3



Fire and Explosion

Preventive Measures

♦ Make ABC fire extinguishers accessible in the work area.

♦ Store flammables in Underwriter’s Laboratory and Occupational Safety and Health

Administration (OSHA) approved metal safety cans equipped with spark arrestors.

♦ Store flammable containers more than 50 ft from the rig. Store portable (flammable)

tanks more than 100 ft from the rig.

====================== HAZARDS IDENTIFICATION ========================

EMERGENCY OVERVIEW: ------------------- Clear Liquid With Hydrocarbon Odor. May Be Dyed For Identification. Danger! Harmful or Fatal If Swallowed. Aspiration Hazard If Swallowed--Can Enter Lungs and Cause Damage. May Be Irritating To the Eyes and Respiratory Tract. Causes Skin Irritation. Vapors May Be Harmful. Possible Cancer Hazard - Contains Material Which May Cause Cancer Based On Animal Data. Combustible Liquid & Vapor.

POTENTIAL HEALTH EFFECTS: -------------------------

DRAFT

SKIN: ----- Repeated or prolonged contact may result in defatting, redness, itching, inflammation, cracking and possible secondary infection. May cause allergic reactions in some individuals. Absorption from prolonged or massive skin contact may cause poisoning. High pressure skin injections are Serious Medical Emergencies. Injury may not appear serious at first; within a few hours, tissue will become swollen, discolored and extremely painful (see Notes to Physician section).

EYE: ---- Exposure to vapors, fumes or mists may cause irritation.

INHALATION: ----------- May cause respiratory tract irritation. Exposure may cause central nervous system symptoms similar to those listed under "Ingestion" (see Ingestion section). Degenerative changes in the liver, kidneys and bone marrow may occur with prolonged, high concentrations. Repeated or prolonged exposures may cause behavioral changes.

INGESTION: ---------- Aspiration into lungs may cause pneumonitis. May cause gastrointestinal disturbances. Symptoms may include irritation, nausea, vomiting and diarrhea. May cause harmful central nervous system effects. Effects may include excitation, euphoria, headache, dizziness, drowsiness, blurred vision, fatigue, tremors, convulsions, loss of consciousness, coma, respiratory arrest and death.

SPECIAL TOXIC EFFECTS: ---------------------- Based on animal studies, repeated overexposure may produce skin tumors upon repeated and prolonged skin contact in the absence of good personal hygiene. However, long-term dermal application studies of similar materials, i.e. middle distillates, in animals have shown that skin tumors are produced only when marked and prolonged skin irritation takes place during the study. Therefore, this product should not present a significant hazard of skin tumor formation when the "Skin Protection" recommendations are followed. IARC has determined that diesel engine exhaust is probably carcinogenic to humans. (IARC Class- 2A). Lifetime exposure to whole diesel exhaust has been shown to cause cancer in laboratory animals. NIOSH recommends that whole diesel exhaust be regarded as a potential occupational carcinogen. Warning: The use of any hydrocarbon fuel in an area without adequate ventilation may result in hazardous levels of combustion products and inadequate oxygen levels. IARC has determined that occupational exposures in petroleum refining are probably carcinogenic to humans.

======================== FIRST AID MEASURES ==========================

SKIN: ----- Remove contaminated clothing immediately. Wash area of contact

DRAFT

thoroughly with soap and water. Get medical attention if irritation persists. High pressure skin injections are serious medical emergencies. Thermal burns require immediate medical attention. Get immediate medical attention.

EYE: ---- Flush immediately with large amounts of water for at least 15 minutes. Eyelids should be held away from the eyeball to ensure thorough rinsing. Get medical attention if irritation persists. Thermal burns require immediate medical attention.

INHALATION: ----------- Remove affected person from source of exposure. If not breathing, ensure clear airway and institute cardiopulmonary resuscitation (CPR). If breathing is difficult, administer oxygen if available. After administration of oxygen, continue to monitor closely. Get medical attention.

INGESTION: ---------- Do not induce vomiting because of danger of aspirating liquid into lungs. Get immediate medical attention. If spontaneous vomiting occurs, monitor for breathing difficulty.

NOTES TO PHYSICIAN: ------------------- In case of ingestion, gastric lavage with activated charcoal can be used promptly to prevent absorption. Consideration should be given to the use of an endotracheal tube, to prevent aspiration. Individuals intoxicated by Diesel Fuel No. 2 should be hospitalized immediately, with acute and continuing attention to neurologic and cardiopulmonary function. Positive pressure ventilation may be necessary. After the initial episode, individuals should be followed for changes in blood variables and the delayed appearance of pulmonary edema and chemical pneumonitis. Such patients should be followed for several days or weeks for delayed effects, including bone marrow toxicity, hepatic and renal impairment. Individuals with chronic pulmonary disease will be more seriously impaired, and recovery from inhalation exposure may be complicated. In case of skin injection, prompt debridement of the wound is necessary to minimize necrosis and tissue loss.

If leak or spill has not ignited, ventilate area and use water spray to disperse gas or vapor and to protect personnel attempting to stop leak. Use water to flush spills away from sources of ignition. Do not flush down public sewers or other drainage systems. Exposed firefighters must wear MSHA/NIOSH approved positive pressure self-contained breathing apparatus with full face mask and full protective clothing.

UNUSUAL FIRE & EXPLOSION HAZARDS: --------------------------------- Irritating and/or toxic substances may be emitted upon thermal decomposition. Dangerous when exposed to heat or flame. Runoff to sewer may cause fire or explosion hazard. Containers may explode in heat of fire.

==================== ACCIDENTAL RELEASE MEASURES =====================

If your facility or operation has an "Oil or Hazardous Substance Contingency Plan", activate its procedures. Take immediate steps to stop and contain the spill. Caution should be exercised regarding personnel safety and exposure to the spilled material. For technical advice and assistance related to chemicals, contact CHEMTREC (800/424-9300) and your local fire department. Notify the National Response Center, if required. Also notify appropriate state and local regulatory agencies, the LEPC and the SERC. Contact the local Coast Guard if the release is into a waterway. Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind; keep out of low areas. (Also see Personal Protection Information section.) Shut off ignition sources; no flares, smoking or flames in hazard area. Stop leak if you can do it without risk. Water spray may reduce vapor; but it may not prevent ignition in closed spaces. Small Spills: Take up with sand or other noncombustible absorbent material and place into containers for later disposal. Large Spills: Dike far ahead of liquid spill for later disposal.

When reporting a spill to the National Response Center or the Coast Guard, you may need to supply the Coast Guard Chemical Hazard Response Information System (CHRIS) code:

11.0 TOXICOLOGICAL INFORMATION

ACUTE TOXICITY DATA:

EYE IRRITATION: This product had a primary eye irritation score (PEIS) of 0/110.0 (rabbit)

SKIN IRRITATION: This product had a primary skin irritation score (PDIS) of 1.1/8.0 (rabbit)

DERMAL LD50: greater than 5 ml/kg (rabbit).

ORAL LD50: 18.8 ml/kg (rat).

INHALATION LC50: 20.7 mg/l (rat)

OTHER TOXICITY DATA: Excess exposure to vapors may produce headaches, dizziness, nausea, drowsiness, irritation of eyes, nose and throat and central nervous system depression. Aspiration of this material into the lungs can cause chemical pneumonia and can be fatal. Aspiration into the lungs can occur while vomiting after ingestion of this product. Inhalation of unleaded gasoline vapors did not produce birth defects in laboratory animals. Ingestion of this material can cause gastrointestinal irritation and diarrhea.

In a long-term inhalation study of whole unleaded gasoline vapors, exposure-related kidney damage and kidney tumors were observed in male rats. Similar kidney effects were not seen in female rats or in mice. At the highest exposure level (2056 ppm), female mice had an increased incidence of liver tumors. Results from subsequent scientific studies have shown that a broad variety of chemicals cause these kidney effects only in the male rat. Further studies have discovered the means by which

DRAFT

the physiology of the male rat uniquely predispose it to these effects. Consequently, the Risk Assessment Forum of the Environmental Protection Agency has recognized that these responses are not predictive of a human health hazard. The liver tumors that were increased in the high-dose female mice are likewise of questionable significance because of their high spontaneous occurrence even without chemical exposure and because the rate of their occurrence is accelerated by a broad spectrum of chemicals not commonly considered to be carcinogens (e.g., phenobarbital). Thus, the significance of the mouse liver tumor response in terms of human health is questionable.

Gasoline is a complex mixture of hydrocarbons and contains benzene (typically no more than 2 volume%), toluene, and xylene. Chronic exposure to high levels of benzene has been shown to cause cancer (leukemia) in humans and other adverse blood effects (anemia). Benzene is considered a human carcinogen by IARC, NTP and OSHA. Over exposure to xylene and toluene can cause irritation to the upper respiratory tract, headache and narcosis. Some liver damage and lung inflammation were seen in chronic studies on xylene in guinea pigs but not in rats.

Solvent "sniffing" (abuse) or intentional overexposure to vapors can produce serious central nervous system effects, including unconsciousness, and possibly death.

12.0 ECOLOGICAL INFORMATION

Ecological testing has not been conducted on this material by BP Amoco.

Remediation Action Plan

Monitoring Well Installation Scope of Work for Contractor Bids


Tigard, Oregon

This document outlines the drilling contractor’s scope of work for well installation activities required

for the completion of the Remedial Action Plan at the above-referenced project Site.

The drilling contractor’s scope of work for this project includes the installation of two groundwater

monitoring wells using direct-push drilling methods. Approximate locations of the wells (MW-3 and

MW-4) are shown on Figure 2. [Note: the building demolition and floor slab removal will be

completed prior to the monitoring well installations]. The contractor’s scope of services includes

well permitting, mobilization, drilling, well construction/installation, decontamination, investigation-

derived waste (IDW, i.e., groundwater and soil cuttings) containment, and demobilization.

SCOPE OF WORK

The Contractor must be currently licensed and bonded to drill and install monitoring wells in the

State of Oregon and shall provide all of the necessary labor, appropriate equipment, and required

materials to complete the scope of work in accordance with all applicable Oregon Water Resources

Department (OWRD) regulations.

The Contractor shall bid for the completion of all tasks as described below.

Safety

A site-specific Health and Safety Plan (HASP) will be provided by Amec Foster Wheeler for review

by Contractor field staff prior to starting work. Daily tailgate safety meetings will be required for all

the Contractor’s on-site employees at the beginning of each day and will be conducted by the

Amec Foster Wheeler field manager.

Level D PPE (including hard hat, safety glasses, steel-toed boots, hearing protection, and high

visibility traffic vest) is the required minimum PPE for all on-Site personnel.

Utility Location

Amec Foster Wheeler will contact the public Utility Notification Center to locate public utility lines in

the area of the boreholes. Amec Foster Wheeler also will arrange for a private utility locating

service to check and mark each of the drilling locations. The Amec Foster Wheeler field manager

will confirm the final drilling locations with the Contractor on Site.

Permitting

The Contractor shall acquire all OWRD permits required for installation of the wells.

DRAFT

Well Installation

• The two (2) monitoring wells will be installed at the proposed MW-3 and MW-4 locations shown

on Figure 2. Final locations may be altered based on the presence of subsurface utilities, field

conflicts, or other project requirements. The Amec Foster Wheeler field manager shall make

the final determination where the drilling locations shall be conducted.

• During drilling, continuous core soil samples shall be collected, beginning 5 feet below ground

surface (bgs) and provided to Amec Foster Wheeler field personnel for field screening and core

logging.

• The Contractor shall furnish materials and install two monitoring wells. Wells shall be

constructed of 2-inch inner diameter Schedule 40 PVC casing and 2-inch inner diameter

Schedule 40 PVC 0.010-inch slotted well screen.

o Monitoring wells will be completed to a total depth of approximately 18 feet bgs with

a 10 foot screen interval (from 8 to 18 feet bgs). The well screen will include a pre-pack

filter, consisting of 10/20 silica sand (or similar), and which shall extend a minimum

distance of 0.5 foot above the top of the well screen.

o The Amec Foster Wheeler field manager will make the final determination of all well

completion depths and screen intervals. The Contractor shall have additional well

construction materials (couplers, caps, screened sections, etc.) available in the event

that the well total depths or screen intervals would need to be increased.

o After well installation, the remaining annular space of the borehold shall then be

filled with hydrated bentonite grout or with bentonite chips as appropriate up to a depth

of 1.5 feet bgs. The upper 1.5 feet bgs to the ground surface shall be completed with a

concrete seal.

o Each well shall be completed to existing ground surface with a traffic-rated,

monument surrounded by a concrete pad with a minimum thickness of 4 inches to divert

rainfall away from the well casing.

Investigative-Derived Waste Management

The Contractor shall provide sufficient plastic sheeting (minimum 6 mil thickness) to lay down in

work areas to prevent all soil cuttings and groundwater from contacting and contaminating the

ground surface.

The Contractor shall contain and transport all groundwater, decontamination water, and drill

cuttings in 55-gallon steel drums, also supplied by the Contractor, with secure closures. Soil and

water IDW shall be segregated and stored in separate drums.

Amec Foster Wheeler will direct Contractor where to place the drums for on-Site storage and

provide appropriate labels for the drums. The Contractor shall have the necessary equipment to

transport the filled IDW drums to the designated staging location.

Decontamination

Prior to arrival at the project Site, the drill rig, drill casing, support vehicle(s), and other equipment

shall be decontaminated by the Contractor to the satisfaction of the Amec Foster Wheeler field

manager. If any equipment does not arrive in a satisfactory condition, then the equipment must be

returned to the Contractor’s shop for decontamination prior to use on the Site.

During the project, decontamination of the drill casing and equipment shall be conducted by the

Contractor in an on-Site designated area that is covered and contained by plastic cover listed in the

prior section.

Upon completion of all drilling activities, decontamination of the drill rig, drill casing, support

vehicle(s), and equipment shall be conducted, to the satisfaction of the Amec Foster Wheeler field

manager, in an on-Site designated area. All decontamination water shall be contained, transferred

into 55-gallon drums, properly labeled, and stored at the designated site IDW staging area.

Dear Ms. Kuiper:

RE: SHPO Case No. 15-0389

Sample collection, building demo, soil removal, groundwater wells

Our office recently received a request to review your application for the project referenced above. In checking our statewide archaeological database, it appears that there have been no previous surveys completed near the proposed project area. However, the project area lies within an area generally perceived to have a high probability for possessing archaeological sites and/or buried human remains. In the absence of sufficient knowledge to predict the location of cultural resources within the project area, extreme caution is recommended during project related ground disturbing activities. Under state law (ORS 358.905 and ORS 97.74) archaeological sites, objects and human remains are protected on both state public and private lands in Oregon. If archaeological objects or sites are discovered during construction, all activities should cease immediately until a professional archaeologist can evaluate the discovery. If you have not already done so, be sure to consult with all appropriate Indian tribes regarding your proposed project. If the project has a federal nexus (i.e., federal funding, permitting, or oversight) please coordinate with the appropriate lead federal agency representative regarding compliance with Section 106 of the National Historic Preservation Act (NHPA). If you have any questions about the above comments or would like additional information, please feel free to contact our office at your convenience. In order to help us track your project accurately, please reference the SHPO case number above in all correspondence.This letter refers to archaeological resources only. Comments pursuant to a review for above-ground historic resources will be sent separately.

Sincerely,

7376 SW Durham Rd

Dear Ms. Kuiper:

RE: SHPO Case No. 15-0389

Sample collection, building demo, soil removal, groundwater wells

We have reviewed the materials submitted on the City of Tigard & EPA Environmental Assessment Saxony Pacific Property project, and we concur with the determination that the property at 12535 SW Main Street in Tigard is not eligible for listing in the National Register of Historic Places. We also concur that there will be no historic properties affected for this undertaking. This letter refers to above-ground historic resources only. Comments pursuant to a review for archaeological resources have been sent separately.

This concludes the requirement for consultation with our office under Section 106 of the National Historic Preservation Act (per 36 CFR Part 800) for above-ground historic properties. Local regulations, if any, still apply and review under local ordinances may be required. Please feel free to contact me if you have any questions, comments or need additional assistance.
