ASBESTOS, LEAD BASED PAINT AND PCB SURVEY REPORT

Major M&R Building 1 Exterior USCG-Base Seattle, Building 1

1519 Alaskan Way South Seattle, King County, Washington

Terracon Project No. 81147014

March 7, 2014

1.0 INTRODUCTION

Terracon conducted an asbestos, lead-based paint and polychlorinated biphenyls (PCB) containing paint survey of the interior and exterior materials at window installations, exterior surfaces, select roof portions and the south entrance of the United States Coast Guard (USCG) - Base Seattle, Building 1, located at 1519 Alaskan Way South in Seattle, King County, Washington. The survey was conducted on February 18 and March 4, 2014, by an Asbestos Hazard Emergency Response Act (AHERA)-accredited asbestos inspector in general accordance with the Master Subcontract Agreement (MSA) dated August 9, 2013, and the email authorization dated February 11, 2014, between Terracon and EnviroApplications, Inc. (EAI) authorizing Terracon to perform this service. Interior and exterior building components were surveyed and homogeneous areas of suspect asbestos-containing materials (ACM), suspect lead-based paints (LBP) and suspect PCB containing paints were visually identified and documented.

Although reasonable effort was made to survey inaccessible suspect materials, additional suspect but unsampled ACM, LBP and PCB containing paint could be located in walls, in voids or in other concealed areas. Suspect ACM samples were collected in general accordance with the sampling protocols outlined in United States Environmental Protection Agency (EPA) 40 Code of Federal Regulations (CFR) 763.86. Samples were delivered to accredited laboratories for analysis by polarized light microscopy (PLM) for asbestos samples, flame atomic absorption spectrometry (FAAS) for LBP samples and Environmental Protection Agency (EPA) Method 8082 (gas chromatography) for PCB samples.

1.1 Project Objective

We understand this asbestos, lead-based paint, and PCB containing paint survey was requested due to the planned replacement of the buildings windows, select roof portions and south entrance doorway. It should be noted that adverse weather conditions did not allow for sampling/patching of roof portions outside of the north portion of the 2nd floor balcony/emergency exit walkway area.

EPA regulation 40 CFR 61, Subpart M, National Emission Standards for Hazardous Air Pollutants (NESHAP), prohibits the release of asbestos fibers to the atmosphere during renovation or demolition activities. The asbestos NESHAP requires that potentially regulated asbestos-containing building materials be identified, classified and quantified prior to planned renovation activities. The NESHAP authority for King County is the Puget Sound Clean Air Agency

(PSCAA).

The Department of Labor and Industries (L&I) enforces the Washington Industrial Safety and Health (WISHA) Standard for Lead in Construction, Washington Administrative Code (WAC) 296- 155-176, which defines the lead exposure limits for all construction workers performing demolition and/or renovation activities. Should lead be detected at any concentration, WAC 296-155-176 provides the appropriate methods of compliance to ensure worker safety from potential lead exposure.

The State of Washington Hazardous Waste and Toxics Reduction (HWTR) Program affects persons who generate, transport, transfer, recycle, treat, store, or dispose of regulated dangerous wastes, as defined in the Dangerous Waste Regulations (173-303 WAC). Solid wastes, including demolition/renovation debris, must be evaluated to determine if the waste designates as lead-containing dangerous waste prior to disposal.

The Toxic Substances Control Act (TSCA) of 1976 addresses the production, importation, use, and disposal of specific chemicals, including PCBs. Part 761 of the TSCA rule establishes prohibitions of, and requirements for, the manufacture, processing, distribution in commerce, use, disposal, storage, and marking of PCBs and PCB items. Part 761.20 prohibits the use of any PCB, or any PCB item, regardless of concentration, other than in a totally enclosed manner.

2.0 BUILDING DESCRIPTION

The site is developed with a 5-story structure (not including the basement) comprised of cast-in-place concrete exterior and central core (stairwell/elevator shaft) walls. Interior corridor and partition walls are primarily gypsum block with wood-framed partition walls in some areas.

Interior vertical finishes observed on perimeter walls consisted primarily of plaster with areas of gypsum wall board (4th floor southeast window „deletes‟) and glass. Exterior vertical finishes consisted of plaster, glass and exterior insulating foam system (EIFS) apparently installed over the structures original plaster in many areas. Exterior horizontal finishes consisted primarily of concrete, plaster, wood and single-ply rubber membrane roofing applied over historical membrane and asphalt roof systems (2nd floor balcony/emergency exit walkway).

3.0 ASBESTOS FIELD ACTIVITIES

The survey was conducted by AHERA-accredited asbestos inspector Adam Stauffer. A copy of Mr. Stauffer’s asbestos inspector training certificate is attached as Appendix F. The survey was conducted in general accordance with the sample collection protocols established in EPA regulation 40 CFR 763, the Asbestos Hazard Emergency Response Act (AHERA). A summary of survey activities is provided below.

3.1 Visual Assessment

Survey activities began with visual observation of the interior and exterior of the areas that will potentially be disturbed during renovation activities in order to locate and identify homogeneous areas of suspect ACM. A homogeneous area (HA) consists of building materials that appear similar throughout in terms of color and texture. The assessment was conducted throughout visually accessible areas of the exterior walls, interior walls at window installations, select roof areas, and south entrance doorway building components.

Building materials identified as concrete, glass, wood, masonry, metal or rubber were not considered suspect ACM.

3.2 Physical Assessment

A physical assessment of each homogeneous area of suspect ACM was conducted to assess the friability and condition of the materials. A friable material is defined by the EPA as a material which can be crumbled, pulverized or reduced to powder by hand pressure when dry. Friability was assessed by physically touching suspect materials.

3.3 Sample Collection

Based on results of the visual observation, bulk samples of suspect ACM were collected in general accordance with AHERA sampling protocols. Random samples of suspect materials were collected in each homogeneous area. The inspector collected bulk samples using wet methods, as applicable, to reduce the potential for fiber release. Samples were placed in sealable containers and labeled with unique sample numbers using an indelible marker.

Terracon collected 35 bulk samples from 9 homogeneous areas of suspect ACM. A summary of all samples collected is included as Appendix A.

Responsive ■ Resourceful ■ Reliable 4

3.4 Sample Analysis

Bulk ACM samples were submitted under chain of custody to Seattle Asbestos Test (SAT) of Lynnwood, Washington for analysis by polarized light microscopy (PLM) with dispersion staining techniques per EPA methodology (600/R-93/116). The percentage of asbestos, where applicable, was determined by microscopic visual estimation.

SAT is accredited under the National Voluntary Laboratory Accreditation Program (NVLAP Accreditation No. 200768-0).

4.0 ASBESTOS REGULATORY OVERVIEW

The NESHAP regulation for asbestos regulates asbestos fiber emissions and asbestos waste disposal practices. It requires the identification of existing asbestos-containing materials (ACM) according to friability prior to demolition or renovation activity. Friable ACM is a material containing more than 1% asbestos that, when dry, may be crumbled, pulverized or reduced to powder by hand pressure.

The NESHAP regulation classifies ACM as either regulated asbestos-containing material (RACM), Category I non-friable ACM or Category II non-friable ACM. RACM includes all friable ACM, along with Category I non-friable ACM that has become friable or will be or has been subjected to sanding, grinding, cutting or abrading, and Category II non-friable ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder in the course of renovation or demolition activity. Category I non-friable ACMs are exclusively asbestos-containing packings, gaskets, resilient floor coverings, floor covering mastics and asphalt roofing products that contain more than 1% asbestos. Category II non-friable ACM are all other non-friable materials other than Category I non-friable ACM that contain more than 1% asbestos. RACM must be removed prior to renovation or demolition activities.

Washington Administrative Code (WAC) 173 400 075 adopts the federal NESHAP rule by reference. In the State of Washington, authority to administer NESHAP requirements is delegated to the regional air pollution authorities (e.g., the local Clean Air Agency or the Washington State Department of Ecology). In King County, the NESHAP requirements are administered by the Puget Sound Clean Air Authority (PSCAA). PSCAA must be notified at least 10 working days prior to the demolition of any structure with a projected roof area greater than 120 square feet, regardless of whether any asbestos was identified. Notification is not required for renovation projects, unless the project involves the disturbance of friable asbestos containing materials. The owner or operator must also provide the Washington State Department of Labor and Industry (L&I) with written notification at least 10 working days prior to the commencement of asbestos

Responsive ■ Resourceful ■ Reliable 5 removal projects involving at least 10 linear feet or 48 square feet of RACM. Removal of RACM must be conducted by a State of Washington-certified asbestos abatement contractor.

In the State of Washington, worker exposures to asbestos are governed by L&I‟s Division of Occupational Safety and Health (DOSH). The administrative rule WAC 296-62-07705 requires that employee exposure to airborne asbestos fibers be maintained below 0.1 asbestos fibers per cubic centimeter of air (0.1 f/cc) as an eight hour time weighted average. State of Washington Occupational Safety and Health rules also classify construction and maintenance activities which could disturb ACM, and specify work practices and precautions which employers must follow when their employees engage in each class of regulated work.

5.0 LEAD BASED PAINT FIELD ACTIVITIES

In conjunction with the asbestos survey, Terracon personnel visually assessed interior and exterior areas of the site structure slated for renovation, and performed limited LBP sampling that consisted of collecting eight (8) paint chip samples from various painted components. All lead samples were submitted under chain of custody to EMSL Analytical, Inc. (EMSL), of Cinnaminson, New Jersey. The LBP samples were analyzed by flame atomic absorption spectrometry per EPA Method 7000B. EMSL is accredited under the Environmental Lead Laboratory Accreditation Program (ELLAP No. 100194).

6.0 LEAD BASED PAINT REGULATORY OVERVIEW

Lead is regulated by the EPA, the Washington State Department of Ecology (Ecology), the United States Occupation Safety and Health Administration (OSHA) and WISHA (enforced by L&I). The EPA regulates lead use, while both the EPA and Ecology regulate removal, and disposal. OSHA and WISHA both regulate lead exposure to workers. The EPA defines LBP as paint, varnish, stain, or other applied coating that contains lead equal to or greater than 1.0 mg/cm2, 5,000 mg/kg, or 0.5% by dry weight as determined by laboratory analysis. For the purpose of the OSHA lead standard, lead includes metallic lead, all inorganic lead compounds, and organic lead soaps. A synopsis of the OSHA regulations (29 CFR 1926.62) and the applicability are as follows:

The OSHA Interim Lead Standard for Construction (29 CFR 1926.62) applies to all construction work where an employee may be occupationally exposed to lead. All work related to construction, alteration, or repair (including painting and decorating) is included. The lead-in-construction standard applies to any detectable concentration of

Responsive ■ Resourceful ■ Reliable 6 lead in paint, as even small concentrations of lead can result in unacceptable employee exposures depending upon on the method of removal and other workplace conditions.

Similar to the OSHA standard, the WISHA Standard for Lead in Construction, states that if lead is present in the workplace in any quantity WISHA requires that demolition activities be conducted in accordance with WAC 296-155-176, lead Safety Standards for Construction

Work.

In accordance with Ecology‟s Dangerous Waste Regulations, solid wastes must be designated to see if they are dangerous wastes before disposal unless they are exempted or removed from the dangerous waste regulations. If any of the samples are reported with leachable lead concentration of 5.0 mg/L or more, then the waste must be classified and disposed of as dangerous waste.

7.0 PCB CONTAINING PAINT FIELD ACTIVITIES

In conjunction with the asbestos survey, Terracon personnel visually assessed the exterior insulation and finishing system (EIFS) paint on the site structure slated for renovation, and performed limited PCB sampling that consisted of collecting three (3) paint chip samples from various painted EIFS components. All PCB samples were submitted under chain of custody to NVL Labs Inc. (NVL), of Seattle, Washington. The PCB samples were analyzed by gas chromatography per EPA Method 8082. NVL is accredited under the Washington State Department of Ecology Environmental Laboratory Accreditation Program (No. C797).

8.0 PCB CONTAINING PAINT REGULATORY OVERVIEW

The Toxic Substances Control Act (TSCA) of 1976 addresses the production, importation, use, and disposal of specific chemicals, including PCBs. Part 761 of the TSCA rule establishes prohibitions of, and requirements for, the manufacture, processing, distribution in commerce, use, disposal, storage, and marking of PCBs and PCB items. Part 761.20 prohibits the use of any PCB, or any PCB item, regardless of concentration, other than in a totally enclosed manner.

For the most part, EPA regulates the storage and disposal of PCB wastes under TSCA section 6(e)(1) authority, rather than under the Resource Conservation and Recovery Act (RCRA), unless the PCB waste also meets the definition of RCRA hazardous waste. However, to better manage PCB waste, EPA has promulgated requirements for a tracking system that is similar to the “cradle-to-grave” tracking system for hazardous wastes under the RCRA Subtitle C Program.

Some PCB materials are classified as “PCB bulk product waste” for the purposes of disposal.

PCB bulk product waste is waste derived from manufactured products containing PCBs in a non-liquid state, at any concentration where the concentration at the time of designation for disposal was greater than or equal to 50 ppm PCBs. PCB bulk product waste includes paint.

The significance of the PCB bulk product waste designation is that many of the rules that apply to other types of PCB wastes do not apply to PCB bulk product waste.

9.0 FINDINGS AND RECOMMENDATIONS

Asbestos

Laboratory analysis did not identify asbestos in any of the 35 samples submitted.

Appendix A identifies the homogeneous areas sampled, sample identification numbers, material descriptions, and analytical results. Laboratory analytical reports and chains of custody are included in Appendix D. In addition Appendix E contains the sample location plans: Figures 1-3

– Asbestos, Lead and PCB Sample Locations.

In the event that unsampled suspect ACM is discovered during renovation/demolition activities, Terracon recommends that the renovation contractor contact EAI and Terracon immediately upon discovery, so that samples of the suspect ACM can be collected and analyzed in order to classify, and/or quantify the material.

Lead

Based on a review of the analytical results, three (3) of the eight (8) sampled components were found to contain lead that exceeded 5,000 mg/kg (equivalent to 5,000 parts-per-million or 0.5% by weight), which is the maximum concentration to be considered non-LBP as defined by the

EPA.

Appendix B identifies the color sampled, substrate, building component, sample identification numbers, location, condition, and analytical results. Laboratory analytical reports and chains of custody are included in Appendix D. In addition Appendix E contains the sample location plans:

Figures 1-3 – Asbestos, Lead and PCB Sample Locations.

This LBP survey was limited to readily observable and accessible surfaces. Terracon cannot guarantee all other building components (besides those noted above) to be LBP free as the possibility exists that LBP coated surfaces may be hidden from sight or in inaccessible locations, or the homogeneous construction areas identified may not be truly homogeneous.

This limited LBP survey was not performed to the United States Department of Housing and Urban Development‟s (HUD) Guidelines for the Evaluation and Control of Lead-Based Paint

Hazards in Housing standards. It should be understood that this LBP survey is not considered to be comprehensive in nature, and the results are not intended to be used to determine lead hazards, develop abatement plans, or prepare detailed cost estimates for abatement.

According to the L&I, abatement of LBP is not required prior to demolition. However, Terracon recommends that the results of this sampling be provided to your renovation contractor, who should subsequently be responsible for determining lead hazards.

In accordance with Ecology‟s Dangerous Waste Regulations, solid wastes must be designated to see if they are dangerous wastes before disposal unless they are exempted or removed from the dangerous waste regulations. Therefore Terracon recommends that representative samples of the building renovation/demolition waste stream be tested through laboratory analyses in order to determine if the waste is hazardous. Specifically, toxicity characteristics leaching procedure (TCLP) sampling should be performed and samples analyzed for leachable lead. If the samples are reported with a leachable lead concentration of 5.0 mg/L or more, then the waste must be classified and disposed of as hazardous waste.

PCBs

Based on a review of the analytical results, none of the three (3) sampled components were found to contain detectable levels of PCBs.

Appendix C identifies the color sampled, substrate, building component, sample identification numbers, location, condition, and analytical results. Laboratory analytical reports and chains of custody are included in Appendix D. In addition Appendix E contains the sample location plans:
