INTRODUCTION

On February 5th and 6th, 2008, Industrial Hygiene Resources (IHR) performed an asbestos and lead (Pb) paint survey on the Consolidated Service Center Facility, Building 2610 for HDR Engineering, Inc., of Boise, Idaho. Building 2610 is located at 480 E-Street on the Mountain Home Air Force Base (MHAFB) near Mountain Home, Idaho. Mr. Zach Hall, PE, PMP of HDR Engineering, Project Manager, authorized the survey. The survey was conducted to identify asbestos containing building materials (ACBM) and lead (Pb) based paints, prior to disturbance for remodeling or demolition purposes. This asbestos and lead survey meets EPA, DEQ and OSHA regulatory requirements. Mr. Hall provided IHR with a copy of the floor plan of the building. Mr. Ed O’Reilly, represented MHAFB and Mr. Larry Rodgers, CES/CEOHV provided IHR with access to the building and previous sampling data.

BACKGROUND

The structure is primarily one-story with approximately 49,000 square feet of building space with various elevated storage and mezzanines. The original portion of the building was built in the 1970’s, with additions to the east and west ends of the original building in the 1980’s. The building exterior is a concrete “Tip up” construction design with an exposed aggregate architectural finish. The interior walls are wood and metal framed covered with drywall, and the floors are concrete on the ground floor and wood on the mezzanine.

The roof is relatively flat and has approximately 1” of gravel ballast which was recently replaced. The roof is a “Malarkey” built-up roof system, consisting of gravel ballast over 4-ply, hot mopped membranes, over 4” rigid insulation, over ¾” perlite. All areas of the building were inspected except the Post Office where because of security access was denied (see figure 1).

ASBESTOS SAMPLING

AHERA Building Inspectors, Jeff Brown, and Steve Mabe, met with Mr. Larry Rodgers (MHAFB Environmental Operations) to review existing asbestos sampling data for building 2610. After reviewing the existing data, 42 additional bulk samples of suspect asbestos containing building material (ACBM) were collected. See the attached figures for floor plans, sampling locations and material locations.

ACM, under current regulation is defined as material with an asbestos content greater than 1% by volume. Any sample analyzed by “polarized light microscopy” (PLM) method as containing a trace to less than 10% asbestos must be reanalyzed by “point count method” or may be assumed to be ACM. All samples were analyzed by International Asbestos Testing Laboratories (IATL), of Mount Laurel, New Jersey. IATL is an AIHA accredited laboratory and participant in the NVLAP/NIST program.

POINT COUNTING OF COMPOSITE ANALYSIS (ASBESTOS)

One roof flashing bulk sample was analyzed by PLM as containing greater than 1% asbestos. IHR recommended that sample FL-01-B be analyzed by “Point Counting Analysis” to meet EPA and OSHA requirements. For laboratory results of the sampled materials see Table I of this report. The result of the point counting was:

Sample ID Layer/Description Point Counting Results

FL-01-B Flashing around roof penetrations PC-3.1%, Chrysotile

The flashing material around the roof penetrations will need to be removed prior to and if disturbed during renovation or demolition. The point counting of analysis of greater than (>) 1.00% is the EPA and OSHA threshold of a regulated amount. Point counting of analysis for materials less than (<) 1% is not a regulated asbestos containing material.

The materials <1% may remain in the structure during demolition and may be disposed of as construction debris. IHR recommends that the materials >1% be removed from the structure prior to demolition.

ASBESTOS CONTAINING MATERIALS

CONCLUSION/RECOMMENDATIONS (ACM)

The following identifies the material, location, quantity and condition of all materials identified as containing asbestos and remaining in the structure.

Samples FL-01-A, B & C consists of approximately 100 L.F., of roof flashing that is located around each roof penetration on all three roofs. One of the samples contained greater than 3.0% Chrysotile in the flashing. The material was rated as being in good condition with no visual damage. IHR recommends the material be removed by qualified personnel and disposed of as asbestos containing waste material prior to demolition of the structure.

Certified and trained professional should remove the asbestos containing materials and properly dispose of them in a landfill that accepts such materials. Prior to any removal and/or demolition activities a notification form must be completed and mailed or hand delivered to the local DEQ office in Boise. Asbestos abatement companies are accustom to these forms and can help complete and understand the requirements.

PREVIOUS ASBESTOS SAMPLING REPORT

IHR relied on previous asbestos building inspections and removal documentation that was provided by MHAFB. Two asbestos inspections were completed on building 2610 that were focused on remodeling inside the building. Northern Industrial Hygiene, Inc. of Burien, WA completed an asbestos survey that only included sampling for the remodeling of the 366th SVS/CPU room which is located to the east of the current post office location (see figure & appendix). No asbestos was identified in the wallboard (sheetrock), tan pebbled vinyl, carpet mastics, ceramic tile mastics, or drop-in ceiling panels.

In 1991, HAZTOX of Meridian, Idaho collected bulk samples of green floor tile for the new bakery area project. The green tile was 3-5% Chrysotile, while the mastic was 5-10% Chrysotile. IHR investigated the purported area of the new bakery area and was unable to locate either the green tile or black mastic. This area may have been abated at some time in the past, however, no documents were provided to IHR to substantiate this.

MHAFB also provided an EPA notification of demolition and renovation for the boiler rooms of building 2610. According to the notification, Associated Insulation, Inc. of Sunset, Utah removed 42 linear feet of asbestos piping from the boiler room in July of 2001. All piping in the boiler rooms were fiberglass.

LEAD BASE PAINT SAMPLING

F:\2008\IHR 2008\3836 HDR MHAFB Bldg. 2610\Asbestos and Lead Survey.doc 6

Mr. Brown and Mr. Mabe, collected six (6) paint chip samples that were analyzed for lead (Pb) content. Sample locations, material descriptions and quantities are documented in the attached tables and figures.

The Housing and Urban Development (HUD) and Bureau of Indian Affairs (BIA) have established regulations for lead based paint (LBP). The disturbance of lead (Pb) containing paint is governed by the Occupational Safety and Health Association (OSHA).

Regulated lead (Pb) paint is defined as paint containing > 5,000 parts per million (ppm) or 0.5% lead.

All lead (Pb) containing waste or structural building members to be disposed of must be submitted for Toxic Characterization Leachate Procedure (TCLP) analysis prior to disposal. Any material analyzed as containing > 5 milligrams per liter of leachate must be disposed of as hazardous waste at a proper landfill. All bulk paint chip samples were analyzed by analyzed by IATL of Mt. Laurel, New Jersey and this lab is accredited for this procedure. See the attached figures for general arrangement of the building and sample locations.

LEAD BASE PAINT (LBP)

CONCLUSION/RECOMMENDATIONS (LBP PAINT CHIP)

Two of the six paint chips were analyzed as containing greater than 0.5% lead. The two positive paint chip samples were collected in the Mobility Command Area located on the west end of the building. Pb-04 was collected from the yellow paint on the floor of the mobility area. IHR also noticed that this same yellow paint was located on “push carts” that were inside the mobility area.

Pb-05 was collected from the white paint and red primer on the interior wide-flange steel, vertical beams inside the mobility area. The exterior coating is white and has a red primer as a base. If MHAFB elects to remove the vertical support columns in the mobility area, they can unbolt the columns from the floor and ceiling, and save or store the columns without having to abate them. However, if welding, sanding, or grinding will be involved during the demolition or renovation, then lead abatement would be necessary.
