Survey Summary

On August 15th and 16th, 2011, Anthony Fullerton of Med-Tox Northwest (MTNW) conducted a hazardous building materials (HBM) survey of buildings 455 and 456 owned by the Air National Guard at Paine Field, in Everett, Washington. This work was conducted in preparation for the planned demolition. The buildings were vacant at the time of the survey. This survey was conducted in accordance with Contract W912K3- 10-D-0001.

A building inspector accredited under the Asbestos Hazard Emergency Response Act (AHERA) and employed by Med-Tox Northwest, conducted the building material survey in accordance with federal, state, and local regulations to provide for an assessment of asbestos-containing materials (ACM) in the structure. The applicable regulations require the building owner to identify and dispose of the identified ACM prior to the start of demolition work.

This report identifies building materials that contain asbestos, estimates the quantity of ACM present and documents building materials that potentially contain polychlorinated biphenyls (PCBs) and other hazardous materials. Copies of the inspectors AHERA building inspector certificates and Commercial, Trade and Economic Development (CTED) Risk Assessor certificate are included in Appendix A.

Six (6) materials were identified as ACM in Building 455. These included: 4-inch gray cove base with residual ACM joint compound, cement asbestos board (CAB) siding, Wood eave caulk, white solid fire-stop, gray fibrous fire-stop, and vapor barrier under

CAB.

The joint compound in the un-textured gypsum wallboard system located in building 456 was both determined to contain 2% Chrysotile asbestos in the joint compound, but when composited as a system with gypsum wallboard and tape; the total overall asbestos is less than 1%.

Four (4) materials were identified as ACM in Building 456. These included: 4-inch brown cove base mastic, gray floor leveler with black mastic, and CAB siding, and wood eave caulk.

Except for gypsum wallboard joint compound, these materials must be legally removed and disposed of prior to demolition of the buildings; the wallboard system in 456 contains less than one percent asbestos content and does not require removal as an

ACM.

Med-Tox Northwest inspected the building for cooling systems with potential chlorofluorocarbons (CFC); none were identified.

Building Information

Photographic documentation of the buildings and the major systems described herein are provided in Appendix B.

General and Structural: Buildings 455 and 456 occupy the parcel of property at the Snohomish County Airport (Paine Field) known as the West Parcel. The West Parcel consists of approximately 1.7 acres and is completely surrounded by four (4) paved roadways systems which serve as access to the parcel and surrounding businesses.

Building 455 is approximately 3690 square feet and is situated to the west of building 456 at the near center of the property. Building 456 is to the eastern side of the property and is approximately 2,269 square feet. The property is completely enclosed by a chain-link type fence with limited access. The two structures on the West Parcel were originally constructed as part of the Air Forces support operations on Paine Field and served as the unit's vehicle maintenance shops and motor pool. When the Air Force relinquished the user rights to the buildings to the Washington Air National Guard, the buildings remained in service as vehicle maintenance until the construction and completion of the new vehicle maintenance, now located on the North Parcel.

Both buildings were originally constructed in 1948 and/or 1949. They are wood framed with cement asbestos board siding covered with newer vinyl siding and soffit. The main portions of the buildings were utilized for vehicle maintenance; with support offices, conference rooms, restrooms and mechanical rooms taking up the remaining space.

The building is constructed slab on-grade. The roofs are pitched and have three tab composition shingles.

Heating and Mechanical Systems: Heat for the buildings is provided by gas fired furnaces located in their respective mechanical rooms. The associated duct work runs

September 16, 2011 3 Helix Design overhead with ceiling mounted or overhead diffusers. Ducting in the west offices of Building 455 is wall mounted. This ducting penetrates the walls and has wall mounted diffusers, so the main line feeds several rooms. Office 2 in Building 455 also has a wall mounted electric heater.

The hot water tank for Building 455 is located in the men’s restroom, the hot water tank in Building 456 is located above the restrooms in a mezzanine storage area. Both tanks were un-insulated and the associated pipes were also un-insulated.

Walls/Ceiling: Walls throughout both buildings are finished with un-textured gypsum wallboard systems.

Ceilings in both buildings are primarily open to reveal the wood framing in the main work areas. Office areas, mechanical room, and restrooms in Building 455 have un-textured gypsum wallboard system on the ceiling. In Building 456 the ceiling in the office areas, and conference room have acoustical ceiling tiles in a metal T-grid. Restrooms in Building 456 have un-textured gypsum wallboard systems.

Floor Systems: Floors throughout both buildings is slab on-grade concrete. Floors throughout the work areas have a gray epoxy type finish over the concrete. Office areas have glued down carpeting over concrete. In Building 455 the restrooms have 12-inch gray floor tile and mastic, in Building 456 there is 12-inch beige mottled vinyl tile and mastic in the conference room and sheet vinyl flooring in the restrooms.

Asbestos Survey

The AHERA regulation, 40 Code of Federal Regulations (CFR) 763, is the primary governing regulation when performing asbestos surveys. This regulation was originally enacted for school buildings, but has since been applied to public and commercial buildings by the Asbestos School Hazard Abatement Reauthorization Act (ASHARA) in 1994 and by the Occupational Safety and Health Administration’s (OSHA) worker protection regulations in 1995, specifically 29 CFR 1926.1101(k).

Puget Sound Clean Air Agency (PSCAA) also requires compliance with AHERA’s survey and sampling requirements. This applies to any renovation or demolition activities where suspect ACM may be disturbed. PSCAA is a local agency that receives statutory authority from the U.S. Environmental Protection Agency (EPA) to enforce environmental regulations.

AHERA divides suspect ACM into three categories; “surfacing materials” (i.e., sprayed fireproofing, popcorn ceiling texture, etc.), “thermal system insulation” (TSI) (i.e., pipe or building insulation, etc.), and “miscellaneous materials” (i.e., flooring material, roofing, construction mastics, etc.). The following sections summarize the potential ACMs

September 16, 2011 4 Helix Design identified and for each of these three categories. For a complete listing of suspect materials sampled, see Appendix C.

Lead-Based Paint Summary

Lead was commonly used in most paint products until 1978, when it was banned from residential paints at concentrations greater than 600 parts per million (ppm); however, commercial applications with lead were still utilized and are still available. Lead is poisonous to the human body and presents a potential health hazard during any kind of disturbance (such as maintenance, including grinding, welding, and cutting) and if improperly disposed, where lead can enter drinking water supplies.

EPA defines lead-based paint as a concentration of 1.0 milligram per centimeter squared (mg/cm2) or greater by X-Ray fluorescence (XRF) or 0.5 percent by weight or

September 16, 2011 10 Helix Design greater by total lead analysis (equivalent to 5,000 milligram per kilogram [mg/kg]). This EPA action level triggers requirements for protection of the environment, maintenance workers, and building occupants. It also triggers training and certification requirements for inspectors, project designers, contractors, supervisors, and workers. Although the training requirements only apply to certain residential structures at this time, they could apply to this type of property sometime in the future.

Washington Industrial Safety and Health Administration (WISHA) worker protection regulations has not defined a minimum concentration for regulating lead, and has clarified that lead at any detectable concentration shall be considered regulated (Washington Administrative Code [WAC] 296-155-176, Lead).

Lead in Painted Surfaces

Interior and exterior painted surfaces were tested for lead-based paint (LBP) using bulk sample collection and chemical analysis. A total of six, (6) paint chip samples were collected. Analytical results are provided in Table 3.

Waste Designation Survey

Buildings 455 and 456 wastes consist of all construction materials with the exception of metal and concrete products. There was (1) toxicity characteristic leaching procedure (TCLP) sample collected during this inspection and tested by TCLP analysis for Resource Conservation and Recovery Act (RCRA) metal – lead. Samples 7187.2-AF- TCLP 01 and 7187.2-AF-TCLP 02 are from Building 455, samples 7187.2-AF-TCLP 03 and 7187.2-AF-TCLP 04 are from Building 456. Samples 01 and 03 are from painted CAB, samples 02 and 04 are from all other building materials minus concrete materials and CAB that will make up the waste stream. The result for the TCLP samples are listed in Table 4:

Other Hazardous Building Materials

Chlorofluorocarbons

Med-Tox Northwest inspected the building for cooling systems with potential chlorofluorocarbons (CFC). There were no CFC’s identified in Buildings 455 and 456.

PCB Light Ballasts and Fluorescent Light Tubes

Older fluorescent light ballasts have small capacitors that may contain high concentrations of PCB. Nearly all ballasts manufactured before 1979 contain PCBs. All ballasts manufactured after July 1, 1978 that do not contain PCBs are required to be clearly marked "No PCBs". Unmarked ballasts or ballasts without a date code should be assumed to be PCB ballasts. PCBs are toxic chemicals according to the EPA.

While there is only a small amount, about one ounce, of PCBs in each light ballast capacitor, there are a large number of ballasts in the United States. About half of the one billion ballasts, estimated as currently installed, were manufactured before 1979 and usually contain PCBs. Ballasts manufactured after 1978 may contain a PCB

September 16, 2011 12 Helix Design replacement called Di (2-ethylhexyl) phthalate (DEHP), a probable human carcinogen.

In any case, ballasts should not be disassembled for disposal but collected and sent to a certified recycling/disposal facility.

Fluorescent light fixtures were observed throughout the building. These fixtures were not inspected for the presence of PCB light ballasts due to being in use and the likelihood that many have been replaced since 1978. Determining how many fluorescent lights actually contain PCB ballasts can only be verified economically and safely during demolition. Therefore, all light fixtures are assumed to contain PCB light ballasts; light tubes are assumed to contain mercury. Additionally, exit lights, high intensity discharge (HID) lamps, smoke and heat detectors, and fire extinguishers may be regulated as universal or hazardous waste and will require dismantling and special handling. Table 5 provides a summary of these items in the building:

Total 16 4 41 0 0

Typically, there is one, ballast for every two, light tubes in a fluorescent light fixture;

accordingly, there are approximately twenty seven ballasts in the light fixtures (sixteen in the HID lights and forty five in the fluorescent fixtures) requiring recycling or PCB hazardous waste disposal. There are also approximately ninety light tubes from the fluorescent fixtures and sixteen HID light bulbs that will need to be disposed of prior to demolition.

PCB in Caulking and Paint

PCB’s were used in paint and caulk formulations as drying oils (resins) and plasticizers or softening agents (liquids). Concrete surfaces and equipment, as well as marine or waterproofing applications, used at Federal installations and in the manufacturing and industrial sectors may have painted surfaces containing PCBs.

Med-Tox Northwest recommends that this survey report be placed on-site during renovation and/or demolition and copies provided to the contractor(s) bidding and performing work. WISHA and PSCAA require that the report be on-site and available for review during the entire project duration.

Additional destructive investigation and sampling will be required prior to and during any demolition activities including the following:

1. The doors to the building were not suspect fire doors as they were hollow core wood, metal, roll-up metal, or glass; however, destructive sampling of the doors was not permitted. For verification purposes, prior to any activity that will impact the doors; drill into the doors and door frames to determine if suspect fire protection is located inside.

2. Perform inspection of every pipe penetration in the building prior to removal of pipe systems or demolition to verify all penetrations through any wall/floor material do not contain suspect asbestos materials. This will require destructive investigation.

3. The joint compound was determined to contain asbestos in Building 455. If the gray cove base is removed separately from the gypsum wallboard system, it will require abatement by a certified abatement contractor.

Gypsum wallboard systems containing less than 1% asbestos content as a composite analysis require training and an exposure assessment (at a minimum) during disturbance to ensure employees are not exposed above the permissible exposure limit (PEL) of 0.1 fibers per cubic centimeter (f/cc) as defined in WAC 296-62-077.

Additional documentation, engineering controls, medical evaluations etc., may also be required. Employers (building owner, tenant, and/or contractors) shall verify current regulatory interpretation regarding these materials prior to disturbance. If the gypsum wallboard systems are removed intact WISHA Regional Directive (WRD) 23.30 must be followed.

If complete abatement of ACM is not performed, periodic surveillance should be performed by an AHERA accredited building inspector at least once every three years.

In addition, bi-annual surveillance should be performed by maintenance personnel trained by an AHERA building inspector.

WISHA requires ACM be removed by trained and licensed contractors using certified asbestos abatement workers and supervisors (except for deregulated roofing sealants, mastics, and coatings). A 10-day prior notification is also required before abatement can begin. In addition, PSCAA requires notification and fees prior to beginning removal.

WISHA and PSCAA require this survey report to be placed on-site during renovation and/or demolition and copies provided to the contractor(s) bidding and performing work.

Med-Tox Northwest recommends third party oversight of asbestos and demolition activities by an AHERA accredited building inspector to ensure regulatory compliance and completion of the additional destructive methods recommended herein.

Additionally, Med-Tox Northwest recommends requesting unit pricing from abatement contractors during the bidding process to adjust pricing depending on actual quantities verified in the field.

Lead-Based Paint

All painted surfaces should be assumed to contain at least trace levels of lead in paint, therefore requiring compliance with WAC 296-155-176 during any disturbance of painted surfaces. This requirement will apply to all construction trades, unless painted surfaces are removed during demolition activities, which is typically cost prohibitive.

Lead in paint was not significant in the subject building and is not a concern regarding hazardous waste disposal.

The WISHA criteria are used to determine if materials are hazardous during a demolition. For lead; any percentage found in the material should be an assumed risk to human health. Disposal options are also determined by whether the material contains lead. Some landfills cannot accept lead-containing wastes, even if they pass the leachability test.

The waste streams for Buildings 455 and 456 were determined to be less than the regulated level of 5.0 mg/L. The waste from this project can be disposed of as general construction debris.

PCB

PCB-containing paint on the door frames and concrete floor in building 455 will require remediation as a bulk PCB material. Since no soil was exposed, it is un-likely that PCB contamination is present below the concrete slab. Any remnant concrete with one part per million or more will require removal and disposal as a remediation waste. Med-Tox Northwest recommends testing of concrete substrates after remediation. EPA requires notification prior to PCB remediation including approval of the remediation plan.

September 16, 2011 17 Helix Design

The Air National Guard will need to obtain an EPA/State identification number for legal disposal of PCB’s and the hazardous waste manifest used to track disposal in accordance with 40 CFR 761.50, 40 CFR 761.62, and WAC 173-303. Additionally, work procedures for proper removal and protection of workers should be provided to contractors in accordance with WAC 296-155 and WAC 296-841.

During demolition, the asbestos abatement contractor should be tasked with dismantling light fixtures, checking for PCB-free labels, and recycling the light tubes. Ballasts without PCB-free labels are considered PCB-containing and must be disposed as a hazardous waste; all other light ballasts can be recycled. Additionally, light tubes can be recycled as a universal waste for minimal cost.

Other Hazardous Building Materials

Fluorescent light tubes contain mercury and can be recycled as a universal waste for minimal cost. Any HID, mercury vapor, exit lights, smoke detectors and mercury thermostats should be collected and recycled/disposed appropriately.
