9 2.1 General Preparation 2.0 Asbestos Abatement Proper preparation of the work area prior to asbestos abatement is crucial to the success of asbestos abatement projects. The following will be performed, but not limited to, by the Contractor in preparation of the work area: 1. Critical Barriers: All asbestos abatement work involving friable ACM and nonfriable ACM shall require the installation of critical barriers at all penetrations to the work area. 2. Pre-cleaning: Debris from work areas may need to be removed prior to ACM abatement activities can commence. Debris will not need to be disposed of by the Contractor, only relocated to access the ACM. 3. Polyethylene Sheeting: In general, all fixed objects and architectural surfaces in the work area must be protected from contamination during asbestos removal. 4. Pressure Differential: All work areas must be placed under a pressure differential of at least minus 0.02 inches of water column, with respect to outside areas, prior to disturbance of ACM. In instances where mastic materials are the only type of ACM disturbed in the work area, a pressure differential within the work area will not be necessary. Instead, the intake of a HEPA-filtered exhaust unit or HEPA-filtered vacuum may be placed close to the area where asbestos is being disturbed. 5. There is no power at the Site; therefore, the Contractor will need to provide temporary power and lighting and ensure safe installation of temporary power sources and equipment per applicable electric code requirements. There is no water at the Site; therefore, the Contractor will need to bring water to the Site. 2.2 Preparation for Friable or Nonfriable ACM The following will be performed, but not limited to, by the Contractor in preparation of abating friable or nonfriable ACM: 1. Post warning signs and barrier tape in and around work area as required by all applicable regulatory agencies. 2. Seal off all openings, including but not limited to: corridors, doorways, elevators, skylights, ducts, grills, diffusers, and any other penetrations of work areas 3. Doorways and corridors that will not be used for passage during work must be sealed with critical barriers. These seals must be left in place until final air testing is complete and the results received and approved. Allowances must be made for emergency exits. 4. If appropriate, cover surfaces in the proposed work area, which do not require asbestos removal, with polyethylene sheeting in the following manner: a. Cover walls or erect temporary walls with 2 layers of (4 mil minimum thickness) polyethylene sheeting sealed with tape. This sheeting must be secured by staples and tension nails as necessary to maintain the integrity of containment throughout removal and testing process. The two layers of polyethylene sheeting must be placed so the upper layer can be removed without damaging the integrity of the lower layer. b. Cover floors with 2 layers of (6 mil minimum thickness) polyethylene sheeting sealed with tape, when appropriate. The floor covering must extend at least 12" up the wall to contain leakage. The wall covering must overlap the floor covering. McCabe Engineering & Contracting March Mansfield Foundry Asbestos Abatement Bid Specifications

10 c. Cover ceilings with 2 layers of (4 mil minimum thickness) polyethylene sheeting, sealed with tape, when appropriate. This sheeting must be secured in a manner that shall maintain the integrity of containment throughout removal and testing process. d. For work areas that do not have an adequately flat surface, or have extensive mechanical and/or electrical fixtures attached to the ceiling. The Contractor shall perform initial cleaning of the exposed surfaces at the ceiling prior to removal, and perform wet-cleaning and HEPA-vacuuming during final cleanup. The ceiling area shall be encapsulated prior to final air testing. 2.3 ACM Types, Quantities & Locations The following is a summary of the ACM types, quantities, and locations described in the ACM survey that requires removal by the Contractor: 1. Black mastic under brown floor tile, approximately 450 square feet in Building 61; 2. Black mastic under brown floor tile, approximately 1,440 square feet in Building 39A; 3. 2 Pipe insulation, approximately 40 linear feet in Building 33A; 4. 4 Pipe insulation, approximately 100 linear feet in Building 33; 5. 9 x 9 Green floor tile, approximately 240 square feet in Building 38; 6. Black mastic under brown 12 x 12 floor tile, approximately 1,600 square feet in Building 38; 7. Transite ceiling, approximately 500 square feet in Building 33B1; 8. Pipe insulation, approximately 30 linear feet in Building 33B1; and 9. Transite siding, approximately 14,560 square feet on Building 58, 35A, 33A, 33B, and 33B1. a. Transite siding is located along the exterior and interior walls depending on the building. Please refer to Figure 2 for a Location of Asbestos Map. The condition of the ACM referenced above is likely to be in worse condition since the ACM Survey due to weather and vandalism. Therefore, ACM may no longer be in its original position and now located on the floor beneath its original position. 2.4 ACM Removal Process Asbestos Removal, Friable Materials The Contractor will perform, but is not limited to, the following procedures when removing friable ACM: 1. Prepare Site per Section 2.1 and Spray ACM with amended water using spray equipment capable of providing a mist application to reduce the release of fibers. Saturate friable ACM sufficiently to wet the substrate without causing excessive wetting, dripping, or delamination of the material. 3. Spray the asbestos ACM repeatedly during removal process to maintain wet condition and minimize asbestos fiber dispersion. The spraying must not be used as a technique to remove or dislodge ACM. 4.

14 3.1 Inspections Prior to and During Work 3.0 Inspections, Management, & Monitoring Contractor shall make all work areas available to inspection at all times. Each work area will be inspected by the Owner or Owner s representative accompanied by Contractor: 1. Immediately after initial cleaning has been completed and prior to the application of polyethylene sheeting to exposed surfaces. 2. Immediately prior to the commencement of removal of ACM (after preparation of work area is complete). 3. After removal is complete but prior to the application of any encapsulant to the exposed substrates, and pre-encapsulation air testing. 4. Regular inspections of the HEPA-filtered ventilation system will be performed by the Owner or Owner s representative to ensure filters are not excessively loaded with particulate debris, and are properly seated in HEPA-filtered exhaust units. 3.2 Final Visual Inspections If Owner or Owner s representative finds visible accumulations of asbestos debris in work area after the completion work, the Contractor shall repeat wet-cleaning until work area is in compliance, at Contractor's expense. When an inspection by the Owner or Owner s representative in the presence of Contractor determines that the area is free of accumulations of dust and visible asbestos debris and the final air clearance has been met, decontamination unit shall be removed, the area thoroughly wetcleaned, and materials from equipment room and shower room disposed of as contaminated waste. A final visual inspection will be made after all Contractors materials have been removed from work area and all removal, encapsulation, disposal, and related work is completed. Work area must be well lighted for inspection by Owner or Owner s representative. Insufficient lighting may result in delay of the final visual inspection. All polyethylene sheeting must be removed from work area, with the exception of critical barriers, and decontamination unit. HEPA-filtered exhaust units must remain operational, and pressure differential maintained until final clearance by Transmission Electron Microscopy (TEM) or phase contrast microscopy (PCM) is obtained. 3.3 Air Monitoring General The Contractor is responsible for all air sampling required by federal, state, and local agencies. Personal, area, and pre-encapsulation air samples will be analyzed by an NVLAP- McCabe Engineering & Contracting March Mansfield Foundry Asbestos Abatement Bid Specifications

15 accredited laboratory using NIOSH method 7400 using PCM. In some cases, PCM may be used for final air testing. Final air samples will be analyzed by a laboratory accredited by NVLAP for TEM, using the AHERA Mandatory Transmission Electron Microscopy Method in Appendix A of 40 CFR 763, subpart E Background Air Testing Background air testing will be carried out by the Contractor prior to initiation of work in order to establish background levels of contamination. If air monitoring, during work by the Contractor, shows an increase in airborne fiber concentrations outside containment system, work shall cease until the source of the contamination is found and remedied to the Owner s or Owner s representative satisfaction. Any areas that have been contaminated as a result of Contractor's work shall be cleaned by Contractor at the expensive of the Contractor. Background air samples will be analyzed by PCM. TEM analysis of questionable samples will be made available at the expense of Contractor should he request it Personal Air Sampling Personal air monitoring will be performed by the Contractor and consist of: 1. An 8 hour time weighted average (TWA) for samples collected on 25% of the work force during each 8 hour shift for the duration of the project. 2. Continuous personal monitoring to be conducted during preparation, removal, and final cleanup, unless Type C pressure demand respiratory protection is used. 3. Excursion limit or short term exposure limit (STEL) sampling shall be performed during all phases of the asbestos abatement project to establish the STEL for each job function Conditions for Final Air Testing Final air testing shall take place when removal is complete, the polyethylene sheeting not necessary to the integrity of containment removed, and a visual inspection of work area shows that work area is clean and dry Air Clearance Criteria All clearance samples must pass the criteria set forth by applicable standards Final Air Testing After work area has met the 0.01 fibers/cc standard for the pre-encapsulation test, final air testing will be conducted and analyzed by TEM, when the amount of ACM removed in work area is greater than 160 square feet or 260 linear feet. Final air testing will consist of five TEM samples inside work area and five TEM samples outside work area. The sampling procedures and guidelines in EPA 40 CFR 763 part III will be followed. McCabe Engineering & Contracting March Mansfield Foundry Asbestos Abatement Bid Specifications

16 When the amount of ACM removed in work area is less than 160 square feet or 260 linear feet, the results of the pre-encapsulation PCM air test will be considered as the criteria for Contractor compliance Final Air Testing: Exterior Areas Final air testing will not be required for exterior, open work areas. Instead, a thorough and meticulous inspection will be performed by the Contractor with the Owner or Owner s representative present to determine Contractor compliance Final Air Testing: Glove Bag Procedure Each work area in which glove bag removal has occurred will be visually inspected by the Owner or Owner s representative prior to final air testing. Aggressive sampling procedures will not be used unless work areas are fully contained by critical barriers. Each work area will be tested and analyzed by the PCM method, using static sampling procedures. A TEM final air test of the general areas of glove bag removal may be performed at Owner s or Owner s representative discretion upon failure of a PCM final Failure of Final Air Tests When the results of the final air test show values of airborne asbestos in excess of the final air standard, the Contractor must re-clean work area. The final air testing procedure shall then be repeated at Contractor's expense. 3.4 Completion Upon completion of the asbestos abatement project, the Contractor must submit the following to the Owner or Owner s representative: a. All disposal receipts for asbestos-containing materials acquired during the asbestos abatement project; b. A copy of all daily logs, sign-in sheets, and daily reports; c. The original daily chart recordings from manometers used during the asbestos abatement project; d. A list of the names and signatures of all persons involved in the asbestos removal. Include state of accreditation and accreditation number for each person; e. A certification of compliance statement that all asbestos-containing materials related to these specifications have been removed and disposed of in accordance with all applicable federal, state, and local regulations for asbestos abatement; f. All analytical and air monitoring results; and g. All submittals to the Owner or Owner s representative are expected to be neat, complete, accurate, and readable. McCabe Engineering & Contracting March Mansfield Foundry Asbestos Abatement Bid Specifications

17 After final inspections and final air testing are complete and the results known, the Owner or Owner s representative will advise Contractor of any additional requirements. When a work area fails either the inspection or the final air testing, the area must be re-cleaned, re-inspected and re-tested. The sequence of re-cleaning and re-testing shall continue until the area passes the inspection and the final air test.

25 Introduction McCabe Engineering & Contracting was contracted by the City of Mansfield to perform a predemolition/renovation asbestos survey of the Former Mansfield Foundry Property located at 500 North Main Street, Mansfield, Richland County, Ohio. Please see Figure 1 for site location. The survey was conducted in order to identify and quantify the potential Asbestos Containing Materials (ACM) at the facility. Mr. Jim Smart conducted an initial reconnaissance of the site in August Samples were obtained from readily observable suspected ACM and transported to EA Group, Mentor, Ohio for analysis. The results of the preliminary sampling effort have been included in this report. Mr. Jim Smart (Certified Asbestos Hazard Evaluation Specialist, # 32566) and Edward M. McCabe of McCabe conducted the asbestos survey on September 10, The survey was conducted using non-destructive methods of investigation. Bulk samples were taken of all accessible suspect-building materials and sent to Environmental Hazard Services, Richmond, Virginia, for analysis. A total of fifty-three (53) samples were taken during the course of the main site inspection and initial site reconnaissance. Of the samples analyzed, nine (9) samples were identified as containing asbestos above the regulatory limit of 1%. Two samples, B-61-1 Mastic and 02-1 Mastic, contained 2% Chrysotile and were subsequently point counted to more accurately identify the percentage of asbestos in each. The point count results returned asbestos levels at 1.00% for B61-1 Mastic and 7.25% for 02-1 Mastic. Samples containing more than 1% ACM are identified as: B61-1 Mastic Black adhesive mastic (under and adhered to floor tile) contained 2% Chrysotile, approximately 450 square feet present in Building 61. Due to the asbestos content being close to the regulatory limit of 1%, a point count was performed on this sample to verify the asbestos content of the sample. Point count results returned asbestos levels of exactly 1%, verifying the material to be ACM. B39-A2 Mastic Black adhesive mastic (under and adhered to floor tile) contained 5% Chrysotile, approximately 1,440 square feet is present in Building 39. Siding 1 (also sample #5 from preliminary reconnaissance) Exterior transite siding contained 20% Chrysotile, approximately 14,560 square feet of transite siding is present on the exterior of the facility. The transite starts at the northwest corner of Building 38 between 10 and 12 feet off the ground and extends south then east around the main structure and then to the north encompassing Buildings 35A, 33A, 33B, and 65. B33-1 Pipe insulation contained 35% Chrysotile, approximately 100 linear feet of 4-inch piping is present in Building 33. B33-2 Pipe insulation contained 30% Chrysotile, approximately 40 linear feet of 2-inch piping is present in Building Black adhesive mastic (under and adhered to floor tile) contained 2% Chrysotile, approximately 1,600 square feet is present in a second floor office located in the central portion of the main foundry structure. Due to the asbestos content being close to the regulatory limit of 1%, a point count was performed on this sample to verify the asbestos content of the sample. Point count results returned asbestos levels of 7%, well above the regulatory limit of 1%. 1

26 02-2 Green 9 x9 vinyl floor tile contained 5% Chrysotile, approximately 240 square feet is present in the second floor office of the main foundry structure. B65-1 Transite switchgear ceiling panels contained 40% Amosite, approximately 500 square feet is present in the sub-basement of building 68. The material is in very poor condition. #8 Pipe insulation contained 85% Chrysotile, approximately 30 linear feet was observed in Building 65 during an initial site walk conducted in August All sampling locations are exhibited on the site plan provided as Figure 2. The laboratory data from the subsequent analysis of all samples is provided as Table 1. The hard copy laboratory analytical reports are included as Attachment 1. Site photographs are provided in Attachment 2. Recommendations The sample methodology presumed a homogeneous material. That is to say it was presumed for this sampling event and subsequent report that all similar ceiling tile, siding, and vinyl floor tile (VFT) was the same. Four samples of VFT and mastic returned results above 1% rendering the material ACM. Two of the samples, B61-1 Mastic and 02-1 Mastic, were point counted to verify the asbestos content of each due to the original analytical results returning near 1%. Point count results retuned at 1% and 7% respectively, verifying both to be considered ACM. VFT and mastics, which adhere to their substrates, are listed as Category 1 non-friable materials. Category 1 non-friable materials do not need to be removed prior to demolition if the work area is kept adequately wet during the demolition activities. This would include the four samples of the floor tile and mastic that were identified as ACM. The sample of the transite siding, Siding-1, returned results of 25% Chrysotile, rendering the material ACM. Transite is considered Category 2 non-friable asbestos and would have to be removed prior to demolition activities or activities that may result in the material becoming friable. The piping insulation, samples B33-1, B33-2, and #8 (located in Building 65), present within the facility is considered friable asbestos. The material is listed in poor condition and no longer in use, therefore, should be scheduled for removal as time and funds are available. As renovations and/or demolition occur within the buildings, the probability of those materials to become more damaged is likely. Further, the switchgear ceiling tile located in the sub-basement of Building 65, sample B65-1, contained 40% Amosite and is also considered friable and listed in poor condition. The material should be scheduled for removal with the piping insulation. Now that ACM has been identified in the facility, if the buildings remain and re-development occurs and the asbestos is not removed, according to 29 CFR , a building owner has certain responsibilities to the employees that would perform work related to asbestos containing materials (Class III and IV work defined in Paragraph B, Definitions: and Paragraph K Section 9, Information and Training) and those employees which work adjacent to asbestos containing materials. As outlined in the above referenced standard, certain job tasks, which occur in the identified facility, need to be performed by individuals that have received a certain level of competent training (labeling of materials defined in Paragraph K, Communications of Hazards, Sections 7 and 8). 2

27 Further, the building owner/employer needs to identify/label the location of ACM (friable and non-friable) in the facilities in the form of a written or personal communication as well as actual labeling of accessible ACM and areas where it is likely that ACM will be encountered. Should redevelopment occur, a comprehensive Operations and Maintenance (O&M) program would need to be initiated pending the specific areas and work that would be occurring in the facility. The components of an O&M program are outlined in the Guidance for Controlling Asbestos Containing Materials in Buildings (EPA Purple Book). This document is published by the USEPA, Office of Pesticides and Toxic Substances (EPA 560/ , June 1985). Demolition of the on site structures would necessitate the removal of all of the identified friable asbestos (i.e. pipe wrap and transite ceiling tile) as well as the transite siding, which is considered Category 2 Non-friable requiring its removal due to the material becoming friable during demolition. The floor tiling and mastic samples, considered Category 1 non-friable asbestos, would not have to be removed prior to demolition activities.
