Boelter & Yates, Inc NOTES Background The testwas performed in a residential bathroom where original 1970's vintage Congoleum VATs were existing. The original bathroom tiles have been in use since the time of installation. One week earlier of the date of this test, about one half (%) of the original tiles had been removed and replaced with a new old stock (N.O.S.) 1970's vintage Congoleum vinyl asbestos tile. The residence, located at 225 Fremont Avenue in Seaside Heights, New Jersey, was that of Mr. Don Golemme.1 The test was conducted in an actual residence and therefore is representative of actual conditions. The test was conducted to represent the activities of a worker who would be completely removing flooring materials utilizing pre-1970's techniques. Sampling was performed to reflect the entire term of the activities required to completely remove the floor tile. The test was performed on May 29,2002 by Mr. Scott Wynder, a professional flooring installer of Dunes Floor Covering in Chesterton, Indiana, and Mr. Fred Boelter, serving as a helper. This report presents the results of the test described herein. f Sample Results All samples measured concentrations of total fibers in air which were well below the current U.S. Department of Labor Occupational Safety and Health Administration (USDOL-OSHA) 8-hrTime Weighted Average (TWA) Permissible Exposure Limit (PEL) of 0.1 fiber per cubic centimeter (f/cc). Subsequent definitive analysis determined there were no asbestos fibers present in any area or personal sample. Sample results are presented in the accompanying tables. 1 Mr. Golemme is employed by the Congoleum Corporation of Mercerville, New Jersey. 3 0 Complete Removal -1970 Vintage Congoleum VAT - Residential Bathroom June 27,2002 Page 2 1 METHODOLOGY 1 PCM Sampling Procedure Boelter & Yates, Inc. 2-5 NOTES Samples were collected and analyzed by Phase Contrast Microscopy (PCM) following NIOSH 1. -? Method 7400. Air was drawn through a 25mm, conductive cowl cassette with an 0.8 micron mixed cellulose ester (MCE) filter for collecting airborne particulate. The cassette was connected to a dedicated Gilian servo-drive pump. The pump was used to maintain a flow rate of two (2) titers per minute (Ipm) for both personal and area room air samples. .1T A Brooks rotameter was used to calibrate the pumps prior to and post sample collection. The rotameter was calibrated against a primary standard. ..J The samples were sealed, labeled and shipped to the laboratory for analysis. Samples were signed, placed in an overnight shipping container, sealed, tracked by Airborne, and arrived at the i laboratory by next day air. "Personal" Samples i Personal samples were collected by attaching the cassette in the breathing zone of the individual performing the work for the duration of the test. The sampling pump was worn on the individual's belt. .Homogeneous Sampling Area The residence was composed of a number of rooms. While the removal activities were actually being performed in the bathroom, the adjacent kitchen was the necessary access point to the bathroom. Consequently, the kitchen (130ft2) and bathroom (about 45ft2) were considered one homogeneous sampling area (HSA) of about 175ft2. The total volume of this homogeneous sampling area (HSA) was approximately 1,400ft3. Access to other parts of the residence were -j prohibited by the closing of doors and windows and the establishment of a dual layer critical barrier between the kitchen and living room. . j "Average Room Air* Samples To determine the "average room air' concentration, four (4) random locations were selected in. the bathroom and four (4) random locations were selected in the kitchen. A sampling pump and cassette was placed in each of the eight (8) locations for the duration of the test. "Background Air" Samples for TEM Analysis .i Prior to conducting the test, the room was sampled to verify cleanliness. Ten (10) samples were collected (five inside the HSA and five outside the residence) following a modified AHERA i Protocol. Three (3) blanks were also reserved. Analysis was performed by transmission electron microscopy (TEM) following AHERA Protocol. Prior of conducting the background test, the horizontal surfaces ofthe bathroom and kitchen were wet wiped. Since this was an actual residence, utilization of "aggressive leaf blower" techniques was judged impractical. Consequently, samples were collected under static conditions. This static collection of samples is what modifies the technique from AHERA. Complete Removal -1970 Vintage Congoleum VAT - Residential Bathroom June 27,2002 Page 3 Air was drawn through a 25mm, conductive cowl cassette with an 0.45 micron mixed cellulose ester (MCE) filter for collecting airborne fibers. The cassette was connected to a dedicated Gast high volume pump. The pump was used to maintain a flow rate of 10 liters per minute (Ipm). A BGI rotameter was used to calibrate the pumps prior to, during, and post sample collection. The rotameter was calibrated against a primary standard. Boelter & Yates, Inc NOTES The samples were sealed, labeled and shipped to the laboratory for analysis. Samples were signed, placed in an overnight shipping container, sealed, tracked by Airborne, and arrived at the laboratory by next day air. PCM Light Microscopy Analysis Samples were analyzed in accordance with NIOSH Method 7400. Total fiber counts were determined by phase contrast microscopy (PCM) in accordance with the NIOSH Manual of Analytical Methods, Fourth Edition, dated 8/15/94, A Rules. Values for PCM analysis are provided in the Appendix A and Appendix 6 spreadsheets. The only fibers which are counted are those which are longer than 5 microns and have a length to width ratio equal to or greater than 3:1. PCM analysis counts all fibers meeting the specified dimensions. The analysis is not specific for asbestos but is the method specified to be used in the OSHA regulations. . The PCM laboratory reports are presented in Appendix C. Fiber Type Determination bv Electron Microscopy Air samples were subsequently analyzed in accordance with NIOSH Method 7402. Specific fiber types were determined by transmission electron microscopy (TEM) in accordance with the NIOSH Manual of Analytical Methods, Fourth Edition, dated 8/15/94, ASBESTOS by TEM. Values for TEM analysis are provided in the Appendix A and Appendix B spreadsheets. The only fibers which are counted are those which are longer than 5 microns and have a length to width ratio equal to or greaterthan 3:1. The specific fiber types were determined as a "fraction of optically visible asbestos fibers on the filter". The TEM laboratory reports are presented in Appendix C. AHERA Electron Microscopy Analysis AHERA Protocol transmission electron microscopy (TEM) analysis was performed on all background samples to verify the cleanliness of the HSA prior to beginning the test. The sample analysis was performed as described in the Federal Register Vol. 52, No. 210, the Asbestos Hazard Emergency Response Act (AHERA Protocol). Small squares were cut from each filter, processed appropriately, placed onto 200 mesh copper screens (grids) and transferred to a modified Jaffe Wick Washer containing acetone solvent. After the appropriate processing time, the grids were examined with a JEOL1200EX or 100CX TEM. Grid openings from each sample were scanned at 20.000X. When fibers or structures of various shapes were encountered, they were assessed for morphological characteristics and crystalline structure with selected area electron diffraction (SAED). Complete Removal -1970 Vintage Congoleum VAT - Residential Bathroom June 27,2002 Page 4 The TEM laboratory reports are presented in Appendix D. PLM Light Microscopy Analysis Bulk samples were analyzed for asbestos by Polarized Light Microscopy (PLM) in accordance with guidelines set forth in the EPA Method for Determination of Asbestos in Bulk Building Materials, U.S. EPA/600/R-93-116 (7/93 Edition). Boelter & Yates, Inc. NOTES v The PLM laboratory reports are presented in Appendix E. Statistical Comparisons Data was formatted in spreadsheets for analysis. Statistical functions were performed including maximum, average, minimum, standard deviation, and variance. The spreadsheets in Appendices A and B presents the data and summarize the statistical analyses performed. Laboratory Accreditation The samples were shipped to and analyzed by R. J. Lee Group, Inc. in their Monroeville, Pennsylvania laboratory. R. J. Lee is accredited for TEM analysis by the National Institute of Standards and Technology (NIST) under the National Voluntary Laboratory Accreditation Program (NVLAP) as Lab #101208. R. J. Lee is also accredited for PCM analysis by the American Industrial Hygiene Association (AIHA) as Lab #8204. Video Recording The entire process was video recorded. A Sony Digital Handycam DCR-TRV11 was used to record the activities from various vantage points in the bathroom. Complete Removal - 1970 Vintage Congoleum VAT - Residential Bathroor.; June 27, 2002 Page 5 DISCUSSION OF FINDINGS Residential Setting Testing was performed in an actual bathroom located in a residence at 225 Fremont Avenue in Seaside Heights, New Jersey. The bathroom is an area of about 45ft2 (360ft3) with a configuration as shown in Figure 1. The bathroom is located just ofF the kitchen of the residence(see Figure 2). Access to the bathroom is through the kitchen and consequently the kitchen and bathroom were established as the homogeneous sampling area (see Figure 3). Figure 2 - View from kitchen to bathroom An airtight critical barrier was constructed of a double layer of 6 mil polyethylene sheeting to physically separate the kitchen from the livingroom. One layer was constructed on the kitchen side and one layer was constructed on the living room side. Access to the kitchen was gained through the rear porch. Figure 1 - Bathroom configuration Porch Soulh Qidroow Mh MM* Bedfoocn North BMraoa KKchtn Uvtnfl Room Porch Figure 3 - HSA for the test. All other openings such as doors and windows were closed. The critical barrier is visible in the view from the bathroom to the kitchen shown in Figure 4. Background Sampling Results Figure 4 - Critical barrier from kitchen to living room. Prior to conducting any tests, horizontal surfaces in the homogeneous sampling area were systematically wet wiped. Following the cleaning, a series of background samples 2 3 Complete Removal -1970 Vintage Congoleum VAT - Residential Bathroom June 27,2002 Page 6 1 were analyzed from five (5) area sampling locations inside the homogeneous sampling area in accordance with a modified AHERA protocol. 1 Background samples were collected under "static'' conditions with analysis by AHERA TEM in Boelter & Yates, Inc. accordance with AHERA Protocol.

Consequently, the outdoor air was not an influencing factor in the indoor tests. Results are shown in the spreadsheet presented in Appendix .B. Complete Removal -1970 Vintage Congoleum VAT - Residential Bathroom June 27, 2002 Page 7 A mosaic of tiles were installed in the bathroom (see Figure 5) as a result of a previous test. All are 1970's vintage vinyl asbestos tiles (VATs) as manufactured by Congoleum Corporation. The existing original bathroom tile is shown with its corresponding bulk sample in Figure 6. The tile known as Supertile "Libra" VAT with stock number VA-938 was bulk sampled (i.d. MFM-0502401) and analyzed. The asbestos content of this VAT was determined to be 0.0% chrysotile. Another style (See Figure 7) known as Congoleum Aztec is orange with a star pattern. This tile had been previously bulk sampled (i.d. MFM-0698-004) and analyzed. The asbestos content of the Aztec tile was determined to be 0.02% chrysotile. Figure 7 - Congoleum Aztec vinyl asbestos tile. A third style (See Figure 8) known as Congoleum Ventura has a hexagonal pattern in three different colors. This tile had been previously bulk sampled (i.d. MFM-0698-007) and analyzed. The asbestos content of the Ventura tile was determined to be 0.0% chrysotile. Figure 8 - Congoleum Ventura vinyl asbestos tile. See Appendix E for bulk sample data. Complete Removal -1970 Vintage Congoleum VAT - Residential Bathroom June 27, 2002 Page 8 Tile Removal Test The particular test being performed was a complete removal of the existing tile as would be typical for a repair activity. The bathroom had approximately 40ft2 of tiled area as shown in Figure 9. Mr. Wynder was to remove all the tile from this area. oelter & Yates, Inc. I OT E S During the test, there was no deliberate air movement into or out of the residence. No doors or windows were opened during the testing nor was any mechanical ventilation operated before, during or after any of the test cycles. Since this is an actual residence, however, it is likely that there is a natural ventilation rate due to building envelop leakage. This would represent an actual exposure while performing the tasks. Figure 9 - Area selected for partial removal Mr. Scott Wynder, the professional flooring installer, was asked to perform the activities using typical pre-1970's techniques, tools and methods. The removal was performed entirely by hand using a 6" wide flat blade scraper and af wide wood chisel. Personal and average room air samplers were started prior to beginning the testing. The samplers were stopped after completion of the testing. The samplers were operated for the period of time indicated. During the test cycle, no one left or entered the homogeneous sampling area. During the sampling event, similar procedures were followed as described in Table III: STEP 1 2 3 4 5 6 7 TABLE III-SEQUENCE ACTIVITY Scope project; prepare and stage tools Remove bathroom fixtures Plug the waste piping Remove the baseboard Remove the tile using a fiat blade or chisel Remove high spots of mastic Clean tools and clean debris PHOTO Figure 10 .

Clearly, the results are well below the current OSHA 8-hr Time Weighted Average (TWA) Permissible Exposure Limit of 0.1 f/cc. The Appendix A spreadsheets summarized in the above tables are also depicted graphically in the Appendix A. Complete Removal -1970 Vintage Congoleum VAT - Residential Bathroom June 27,2002 Page 11 CONCLUSIONS An approximately 40 square foot area of bathroom tile was entirely removed while testing for the fiber release from 1970's vintage Congoleum Corporation vinyl asbestos tile (VAT). The entire installation process was demonstrated including removing the fixtures, lifting the tiles, and scraping the adhesive. Eight (8) room air samples and two (2) long term personal samples were collected during the process during each test. The process as tested took slightly less than 60 minutes to perform. Boelter & Yates, Inc. NOTES All sample results show the total airborne concentrations of total fibers to be well below the current OSHA 8-hrTime Weighted Average (TWA) Permissible Exposure Limit (PEL) of 0.1 f/cc. Furthermore, all samples showed zero (0) asbestos fibers when analyzed by definitive analytical techniques. Respectfully submitted, BOELTER & YATES, INC.
