ASBESTOS REINSPECTION

GENERAL SERVICES ADMINISTRATION

FEDERAL CENTER SOUTH, BLDG. 1201 (WA0953KC)

SEATTLE, WASHINGTON

BACKGROUND

EHS International, Inc. (EHSI), a hazardous materials consulting firm, under contract to the General Services Administration (GSA) was tasked by GSA to conduct a hazardous materials reinspection and confirmation sampling in accessible areas at the Federal Center South Building 1201, located at 4735 East Marginal Way, Seattle, WA.

EXECUTIVE SUMMARY OF FINDINGS

The following suspect materials were assumed to be asbestos containing or sampled and identified as either asbestos-containing materials (ACM) or non-ACM in the subject areas of the building:

Asbestos-Containing Materials (ACM) Sampled Non-Asbestos Materials

ACM thermal system insulation (TSI) on piping runs and fittings

Joint Compound (JC)

Vinyl asbestos tile (VAT) and ACM mastic Gypsum wallboard (GWB) Sheet vinyl (SV) with ACM backing and mastic Fiberglass insulation on piping

Cement asbestos board (CAB) window panels Window putty

HVAC vibration cloth Sound board White magnesia joint filler associated with boilers Ductwork insulation

Gray patching material Silver paint Tan trowled-on insulation inside boiler stack 1’x2’ acoustic ceiling tile (ACT)

Brown cove base mastic Red terrazzo White mastic under fiberglass insulation Lath and plaster Black expansion joint caulking between concrete slab flooring

Masonry work (brick, mortar, concrete, etc.) associated with boilers

Red/black roof grout Red brick and gray mortar associated with building structure

Boiler gaskets Black cork pipe insulation Roofing black tar sealant Gray felt pipe insulation

Assumed ACM Gray window sill membrane Fire doors Black terrazzo Welding hood interior insulation 2’x4’ worm and hole pattern suspended acoustic ceiling tile (SACT)

Assumed ACM Sampled Non-Asbestos Materials Gaskets associated with piping Black sealant tape on ductwork Sound board Yellow boiler brick lining Leveling compound Spray applied fireproofing Window caulking Brown carpet mastic 12” ACT with worm and hole pattern and associated mastic 2’x2’ blue rubber floor tile and tan mastic

DAMAGED MATERIAL

Damaged ACM TSI pipe insulation was noted on the first and second floors. Refer to drawings DM-1.0 and DM-2.0 (Appendix H) for approximate locations of the damaged ACM material. Refer to Appendix A, Damaged Materials Sheet, for details.

REINSPECTION

EHSI accomplished an asbestos materials reinspection of the subject building on March 28th, 2007. The intent of the reinspection is to specifically identify, quantify, determine the current condition, assign homogenous sample area numbers (HSA#), and develop an engineer’s cost estimate for removal/disposal of ACM.

EHSI was tasked to use applicable Federal, State, and local guidelines in the accomplishment of its reinspection. EHSI was further tasked to provide a written report for the areas reinspected including identification of all suspect materials and a determination of whether suspect material was ACM.

A spreadsheet listing all of the reinspection data is included in Appendix A.

REINSPECTION FINDINGS

Asbestos-Containing Materials

EHSI reviewed the GSA electronic data files for previous asbestos inspections. A 1994 report by Med-Tox listed pipe TSI on runs and fittings, cove base mastic, VAT and mastic, CAB window panels, HVAC vibration cloths, boiler gaskets, white magnesia joint filler, gray patching material, tan trowled-on insulation in boiler stack interior, white fiberglass mastic, Sheet vinyl, red/black roof grout and black tar sealant as sampled and confirmed asbestos-containing materials. A limited 2005 survey by EHSI listed TSI as a sampled and confirmed asbestos containing material. Additional survey samples taken previously confirmed that the following materials were not ACM: cork insulation on pipes and vessels, gray felt pipe insulation, gray window sill membrane, window putty, spray-on fireproofing, GWB, ductwork insulation, yellow boiler lining brick, red terrazzo, leveling compound, white brick, red brick, silver paint, lathe and plaster, 1’x 2’ ACT, black terrazzo, 2’x4’ SACT, sound board, black sealant tape on ductwork, fiberglass insulation on piping and gaskets associated with piping.

Past renovation activity noted includes:

The second floor has undergone HVAC modifications.

The first floor has undergone renovation including reconfiguration and addition of office spaces.

Thirteen (13) bulk samples of suspect ACM were collected as part of this reinspection.

Summaries of asbestos sampling information including sample number, sample location, material description, and analytical results are included in Table 1 below.

KEY: ACT = acoustic ceiling tile, JC = joint compound, SACT = suspended acoustical ceiling tile, N/A = not applicable, ND = none detected.

* The composite of this GWB and JC sample contains less than 1% asbestos and therefore the layer was found to be non-asbestos. Therefore, based on U.S. Environmental Protection Agency (EPA) guidance, the Puget Sound Clean Air Agency (PSCAA) considers the GWB system including the asbestos-containing joint compound to be a non-asbestos material. Therefore, the material is considered non-ACM.

Demolition of GWB with less than 1% asbestos joint compound is not considered an “asbestos project,” but OSHA does require certain worker training, work practices, notifications, engineering controls, exposure monitoring and supervision.

ACM identified in this survey should not be disturbed unless handled by personnel who are properly trained and certified in asbestos work. Any survey, regardless of how extensive, can miss concealed materials. Demolition and/or renovation activities by contractors may expose concealed suspect ACM. Contingency plans should include stopping work on identification of concealed suspect ACM, evacuation of the area, and sampling by a certified AHERA inspector. Concealed suspect material may include, but is not limited to:

non-fiberglass pipe insulation; spray-applied coatings; cementitious board; asphalt or paper vapor barriers; and mastics.

LIMITATIONS

During reinspection, not all rooms or areas were accessible due to tenant restrictions.

This reinspection was limited to the chemicals and materials identified herein. No effort was made to identify hazardous materials in soil, water, or air, other than those listed herein. Limited destructive inspection (e.g., cutting holes in floors, walls, and ceilings) of the building materials to identify, sample, quantify and determine the condition of concealed suspect building materials was not accomplished for this reinspection. Any reinspection, regardless of how extensive, can miss concealed materials. Contractors should be aware of the potential that demolition activities may expose concealed suspect ACM and should have preplanned contingencies for handling these materials when discovered during demolition work. Any concealed, suspect ACM material that was not sampled or that was assumed to be ACM by this reinspection report when encountered must be assumed to be ACM and treated as such until sampled by a certified AHERA Building Inspector and analyzed by a certified laboratory.

STANDARD OF CARE

The recommendations and conclusions contained in this report represent the professional opinions of EHSI. These opinions are derived in accordance with Federal, State and local environmental and health and safety laws and regulations. This reinspection was accomplished in accordance with applicable Federal, State, and local regulations and industry standards in effect at the time. Other than this, no other warranty is implied or intended.

SAMPLING METHODOLOGY

SAMPLING METHODOLOGY

Asbestos-Containing Materials

The EHSI field inspectors were an asbestos Building Inspector, certified under the requirements of the United States Environmental Protection Agency (EPA) Asbestos Hazard Emergency Response Act (AHERA) regulation 40 CFR 763, Subpart E. Sampling was consistent with the requirements of AHERA, as well as meeting the requirements of State and local regulatory agencies. Samples were collected and analytical data obtained for suspect ACM identified in the facility. The number of bulk samples collected and their locations were based on the AHERA regulation and the guidelines provided by the EPA Document 560/5-85-030a, October 1985, Asbestos in Buildings: Simplified Sampling Scheme For Friable Surfacing Materials. Once collected, bulk samples were sealed to eliminate the possibility of contamination. “Chain-of-custody” tracking was followed to maintain sample integrity during handling and data reporting at EHSI and the analytical laboratory. As specified in 40 CFR Chapter 1 (1-1-87 edition) Part 763, Subpart F, Appendix A, each sample was analyzed using polarized light microscopy (PLM) / dispersion staining techniques, in accordance with U.S. EPA Method 600/R-93/116.

Samples were analyzed for asbestos content by NVL Laboratories, Inc. (NVL), Seattle, Washington, a National Voluntary Laboratory Accreditation Program (NVLAP) accredited laboratory. Only materials containing more than 1% total asbestos were classified as “asbestos-containing” based on EPA, State, and local regulations.

Samples in the report labeled as #QA are Quality Assurance (QA) samples. Split samples were taken from the same location and they were sent to separate laboratories.

QA samples were submitted to, Northern Laboratory and Consulting Services, Inc.

(NLCS), Burien, Washington, another NVLAP laboratory. Copies of both laboratories’ NVLAP certifications are included in Appendix E.
