3 EXECUTIVE SUMMARY Pittsburgh Public Schools retained L. Robert Kimball & Associates, Inc., (Kimball) to conduct an asbestos and hazardous materials inspection of Madison Elementary School, located at 3401 Milwaukee Street in Pittsburgh, Pennsylvania The site consists of one school building and an adjacent maintenance shed. The original building was constructed in 1891, with an addition added in The building is constructed of brick and concrete, and is a four-story building (including basement/crawl space) comprising approximately 46,000 square feet. The storage shed is a 150 square foot, pre-formed, concrete structure that is used to store lawn mowers and yard maintenance equipment. The purpose of the asbestos and hazardous materials inspection was to identify, locate, and quantify asbestos and other potential hazardous materials, such as lead-based paint (LBP), polychlorinated biphenyls (PCB), mercury-containing fluorescent lamps, thermostats, thermometers and switches; chlorofluorocarbons (CFCs), NiCad and lead-acid batteries, and various other stored chemicals. Exterior areas, adjacent to the building, were also inspected for the presence of Underground Storage Tanks (USTs). The asbestos and hazardous materials inspection consisted of an on-site inspection, sampling of suspect asbestos-containing materials (ACM) and lead based paint (LBP), and quantification of all observed potentially hazardous materials. Kimball identified the following materials as testing as ACM in the school: Friable ACM Aircell pipe insulation Fitting insulation on Aircell insulated pipe Pipe fitting insulation - residual debris on fittings Pipe insulation debris on soil crawl space floor Drywall joint compound Non-Friable ACM associated with 12 x 12 beige with green & gray floor tile associated with 12 x 12 brown with dark brown mottling floor tile associated with 12 x 12 salmon and brown floor tile Gray roof patch The following materials have been assumed to be ACM. These materials were not sampled due to inaccessibility to materials, or because sampling would have damaged the function of the component associated with that material: Window caulking Chalkboard/Tackboard mastic L.

7 1.0 Introduction Kimball conducted an inspection of the Madison Elementary School, located at 3401 Milwaukee Street in Pittsburgh, Pennsylvania, to identify, locate, and quantify asbestos-containing materials (ACM) and other hazardous materials, such as mercury-containing fluorescent lamps (including fluorescent, metal halide, high-pressure sodium, and mercury-vapor), thermostats, and other mercury containing items; polychlorinated biphenyls (PCB)-containing ballasts and oil containing equipment; chlorofluorocarbon (CFC)-containing equipment, such as water coolers and building specific air conditioning units; nickel cadmium (NiCad) and lead-acid batteries commonly found in exit signs and emergency lighting units; storage tanks; stored solvents, paints, and other miscellaneous chemicals; and lead-based paint (LBP) systems. The inspection was conducted on June 5, 2006, and from June 19-23, 2006 by Mr. Richard Mance, certified PA Management Planner/Project Designer (#006311), and by Mr. Robert Peterson, field technician. As part of this assessment, bulk samples were collected from accessible suspect asbestos-containing materials and paint systems for laboratory analysis. 2.0 Asbestos-Containing Materials (ACM) Kimball conducted the inspection to identify, locate, and quantify ACM throughout the building. Kimball performed a visual inspection of all accessible areas within the building. An appropriate number of samples were collected of any suspect materials that were observed. Suspect ACM was classified into homogeneous areas, and bulk samples were collected for each homogeneous area based on the random sampling protocol, as described by the United States Environmental Protection Agency (EPA), under the Asbestos Hazard Emergency Response Act (AHERA), or as described. All bulk samples were sealed in plastic vials, given unique sample numbers, and logged with an appropriate chain of custody. The samples were analyzed by International Asbestos Testing Laboratories, Inc. of Mt. Laurel, New Jersey, using Polarized Light Microscopy (PLM) with dispersion staining, as specified by the EPA method 600/R-93/116. Bulk samples with a content of less than 10% asbestos, were also point counted. PLM point count analysis is a more definitive method in determining the percentage of asbestos. IATL is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) for asbestos in bulk sample analysis. Kimball identified a total of fifty (51) homogeneous areas and collected one-hundred thirteen (113) bulk samples of suspect ACM, throughout the building. The following materials have been sampled and found to be ACM. Friable ACM Aircell pipe insulation Fitting insulation on Aircell insulated pipe Pipe fitting insulation - residual debris on fittings Pipe insulation debris on soil crawl space floor Drywall joint compound L.

Kimball also identified twenty-eight (28) mercury vapor lamps in exterior building security light fixtures. No sodium lamps were noted. The term lamp refers to mercury-containing lamps, fluorescent tubes or bulbs, metal halide, high-pressure sodium, and mercury-vapor lamps. L. Robert Kimball & Associates, Inc. 7C:\DOCUMENTS AND SETTINGS\CHRIS MEINERT\DESKTOP\FRD\SCHOOL SITES\MADISON\MADISON WEB PAGE\MADISON HAZMAT REPOR

10 Disposal costs average between 25 and 50 cents per four-foot tube and 75 cents to one (1) dollar per eight-foot tube, plus the cost of transportation and any additional landfill fees. An alternative to disposal is recycling. The average cost to recycle fluorescent tubes is around 10 cents per foot, or about 40 cents per four-foot tube (80 cents per eight-foot tube). The average cost to recycle high intensity discharge (HID) lamps is approximately $2.50 per lamp. Fluorescent tubes were added to the EPA list of universal wastes in Universal wastes are hazardous wastes, with less stringent requirements for storing, transporting, and collection. Under federal law, these lamps are considered hazardous waste if they fail the Toxic Characteristic Leaching Procedure (TCLP) test. Under this test, the waste can contain no more than 0.2 milligrams per liter (mg/l) of mercury. The majority of spent fluorescent and high-intensity discharge (HID) lamps, however, fail the TCLP test. Therefore, it should be assumed that all used lamps are hazardous, unless proven otherwise. Current production fluorescent tubes will fail the TCLP test for mercury, while older (pre-1988 production) tubes will fail the TCLP test for cadmium. HID lamps will fail the TCLP test for both mercury and lead. The Universal Waste Rule did give states the authority to add products to their individual waste rules. According to the Pennsylvania Department of Environmental Protection regulation 25 PA Code 260a., all fluorescent lamps, if hazardous, must be managed as either a universal waste or manifested as hazardous waste. Therefore, it is recommended that all mercury-containing lamps be handled, stored, and transported in such a manner that they are protected from damage and not broken. If impacted by building renovation/demolition activities, all mercury-containing lamps should be removed from each fixture. Mercury-containing lamps should be disposed or recycled in accordance with USEPA and the Commonwealth of Pennsylvania hazardous waste regulations and guidelines. Separate estimated costs to remove/dispose or remove/recycle the lamps are found in Table 2, Hazardous Materials. 3.2 Polychlorinated Biphenyls (PCBs) PCBs can be found in a number of different electrical and hydraulic pieces of equipment. Such equipment typically includes oil-filled power transformers, capacitors, and electric ballasts and pieces of equipments that use hydraulic oil. All ballasts manufactured after July 1, 1978, that do not contain PCBs, are required to be clearly marked No PCBs. Select light fixtures were dismantled during the inspection to verify the ballasts labels. All original 2 tube fixtures and newer 3 tube fixtures inspected housed newer Sylvania Quicktronic and Advance models of ballast, and were labeled as No PCBs. If older ballasts with a date stamp of 1978 or older are encountered, they should be assumed to contain PCBs. There are two primary federal regulations that govern the disposal of PCB ballasts: Toxic Substance Control Act (TSCA) 40 CFR Part 761 Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) or L. Robert Kimball & Associates, Inc. 8C:\DOCUMENTS AND SETTINGS\CHRIS MEINERT\DESKTOP\FRD\SCHOOL SITES\MADISON\MADISON WEB PAGE\MADISON HAZMAT REPOR

11 Superfund Act TSCA regulates leaking ballasts and requires the PCB liquids to be drained and incinerated in a TSCA-approved disposal facility or in a chemical waste landfill. Under the Superfund laws, PCBs are specifically listed as a hazardous substance. Sixteen (16) ballasts collectively contain approximately one pound of PCBs, which meets the requirements for a reportable quantity of waste. Therefore, based on TSCA and CERCLA regulations, PCB-containing ballasts, in excess of 16, must be handled and removed as PCB-containing waste for proper disposal at an EPA-approved chemical waste landfill or high temperature incinerator prior to demolition/renovation of the building. An approved company may also recycle the ballasts. A separate cost estimate is given in Table 2 Cost Estimate, Hazardous Materials. The average cost for high-temperature incineration is $1.50 per pound, which is approximately $5.25 per ballast. The average cost for recycling is $1.00 per pound or approximately $3.50 per ballast. Disposal at a chemical or hazardous waste landfill is based on disposal of a 55-gallon drum of ballasts. The average cost is $ per 55-gallon drum, which is approximately $0.50 per ballast. The costs do not include packaging, transportation, or profile fees. High-temperature incineration or recycling eliminates future CERCLA liabilities, while liability will continue for landfill disposal. The estimated cost to remove and dispose of the assumed PCB-containing electric ballasts is found in Table 2 Cost Estimate, Hazardous Materials. The estimated cost to remove the assumed PCB-containing oil from other PCB-containing equipment is also found in Table Chlorofluorocarbons (CFCs) CFCs are primarily used as a refrigerant and can be found in heating, ventilation, and air conditioning (HVAC) units, refrigerators, freezers, vending machines, and water coolers/fountains. If impacted by building renovation/demolition activities, these units should be properly purged prior to disposal of the units. The CFCs must be handled and purged by properly licensed contractors and/or personnel, abiding by all Federal, State, and local regulations. Kimball identified one (1) walk-in refrigerator/freezer in the cafeteria, one (1) air conditioner unit, one (1) air compressor and one (1) air dryer. This equipment may contain CFCs. Window mount air conditioning units, household style refrigerators and freezers, and vending machines, were not included, as they are not part of the building mechanical system and can be easily transported to another location without releasing any CFCs into the atmosphere. The release of ozone-depleting substances is restricted under the Clean Air Act. All CFCs are required to be purged from the equipment prior to the commencement of demolition/renovation activities. Properly licensed personnel and contractors must be used to handle and purge the CFCs, abiding by all Federal, State, and local regulations. Qualified Pittsburgh Public Schools maintenance personnel should be able to purge and transport the CFC-containing equipment. The cost of handling and purging of the CFC units averages approximately $60.00 per unit. The estimated cost to handle and purge the CFC-containing units is found in Table 2, Hazardous Materials. L.

12 3.4 Batteries Nickel-cadmium (NiCAD) and lead-acid batteries can be typically found in exit signs and emergency lighting units. Exit signs and emergency lighting units that are hard wired into the building electrical system were not included counted in this assessment. Kimball identified one (1) lead-acid battery in the Boiler Room. No exit signs or emergency lights which contain batteries were identified in the school. All batteries should be disposed or recycled in accordance with USEPA and the Commonwealth of Pennsylvania hazardous waste regulations and guidelines. The estimated cost to remove and dispose or recycle the battery found in Table 2, Hazardous Materials. 3.5 Mercury Mercury may be present inside thermostats, thermometers, and laboratory drain traps. Kimball inspected select thermostats present through-out the school. All inspected thermostats appear to be pneumatic types containing no mercury switches. Four (4) gas pressure switches in the boiler room, and four (4) thermometers in boiler and fan rooms were identified. No mercury containing thermostats were observed Thermometers, mercury switches and, if present, thermostats should be disposed or recycled in accordance with USEPA and the Commonwealth of Pennsylvania hazardous waste regulations and guidelines prior to any demolition/renovation activities. The estimated cost to remove and dispose or recycle mercury containing items is found in Table 2, Hazardous Materials. 3.6 Storage Tanks The school grounds were inspected for visual evidence of storage tanks containing fuels or other hazardous materials. No storage tanks were noted. Custodial personnel had no knowledge of boilers previously being fueled by oil. 3.7 Miscellaneous Materials Various solvents, paints, chemicals, equipment and other miscellaneous hazardous materials were found throughout the building. Kimball identified the following: Boiler Room 4 55 gallon drums of commercial cleaning product 1 40 gallon drum of floor stripper lb. bags of rock salt Fan Room L.

Miscellaneous office and cleaning supplies such as printer toner, ink cartages, spray cleaners, and art supplies were not included. 3. Remediation of lead paint is not generally required for building renovation or demolition, therefore cost estimates are not provided. Notes Cost estimates reflect unit pricing averages gained from select Pittsburgh based hazardous remediation firms. NA = Not Applicable 4.0 Lead-Based Paint (LBP) Eight (8) paint systems were sampled through-out the school. Sampled paint systems were found to contain between % and 10 % lead by weight based on laboratory analysis, above the laboratory limit of detection. Any paint showing concentrations of total lead greater than the laboratory limit of detection are considered regulated under the Occupational Safety and Health Administration (OSHA). The OSHA Lead in Construction Standard (29 CFR ) requires all contractors performing demolition or renovation activities to notify and provide training for their employees involved in the alteration and/or repair of lead-containing building components. The contractor is also required to conduct an initial Employee Exposure Assessment. There are no requirements for removing lead based paint during renovation or demolition of buildings however means of minimizing the migration of lead dust must be implemented. In addition, waste stream sampling of renovation/demolition materials is required under the Resource Conservation and Recovery Act (RCRA). The samples were analyzed by International Asbestos Testing Laboratories, Inc. of Mt. Laurel, New Jersey, using ASTM D A Atomic Absorption Spectrophotometry (AAS). IATL is accredited by the American industrial Hygiene Association (AIHI) for metals analysis. The paint chip sampling form and the laboratory analysis are found in Appendix D Lead-based Paint Sample Results. 5.0 Summary Kimball performed an inspection for asbestos and hazardous materials throughout all accessible areas of the Madison Elementary School, located at 3401 Milwaukee Street in Pittsburgh, Pennsylvania Asbestos, lead paint and hazardous materials were identified in the building and included mercury-containing light tubes, thermometers switches, potential PCB-containing light ballasts and equipment, batteries, potential CFC containing equipment, and miscellaneous stored chemicals. Based on the results and findings of the building inspection, Kimball recommends the following: ACM that will be impacted by renovation/demolition activities should be removed and disposed of as ACM waste according to all applicable asbestos regulations. The Pennsylvania Department of Labor and Industry and the Allegheny County Health Department (ACHD) requires that asbestos abatement be completed by certified contractors. Assumed materials should be properly characterized for asbestos content prior to L.
