3 EXECUTIVE SUMMARY Pittsburgh Public Schools retained AGX, Inc., (AGX) to conduct an asbestos and hazardous materials inspection of Northview Pre K 8, located at 310 Mount Pleasant Road in Pittsburgh, Pennsylvania. The building is a brick and concrete, three tiered building, each tier is either one or two stories. The boiler room is on the lowest level and a pipe chase lies beneath the building connecting the different levels. 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 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 accessible suspect asbestos-containing materials (ACM) and lead based paint (LBP), and quantification of all observed potentially hazardous materials. AGX, Inc. identified the following material as testing as ACM in the school: Friable ACM Fitting Insulation on Fiberglass Insulated Lines Non-Friable ACM 9 Beige Floor Tile, and Associated Black Mastic 12 (Various Colors) Floor Tile, contaminated by Associated Black Mastic 9 Grey Floor Tile, and Associated Black Mastic Interior Wall Caulking Exterior Window Caulking Interior /Exterior Window Glazing Sink Undercoating Exterior Wall Cap Mastic The following materials have been presumed 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 the material: Interior Boiler Components Blackboard/Bulletinboard Mastic The estimated cost to remove and dispose of the above-referenced ACM is $146,490. See Table 1 for line item cost estimates. AGX, Inc. identified the following hazardous materials throughout the building: AGX, Inc. 1

4 Mercury-containing fluorescent lamps, thermostats and switches; Refrigerator/freezers, water fountains, and air conditioning units with the potential of containing CFCs; Chemicals such as stored oils, grease and gasoline, paints, floor treatment products, cleaning products, degreasers, and road salt. The estimated cost to remove and dispose the above-mentioned hazardous materials is $11,250 See Table 2 for line item cost estimates. In addition, lead-based paint, as defined by the Occupational Safety and Health Administration (OSHA) was documented as present throughout the building. Remediation of lead based paint is not required prior to building renovation or demolition. Lead-in-air would be an OSHA worker exposure issue, and any contractor would have an obligation to monitor worker exposure and provide appropriate PPE in accordance with 29 CFR In renovated The EPA RRP (Renovation, Repair and Painting) Rule will apply when the renovated facility will be Child Occupied - used by children less than 6 years of age. This means that all contractors who disturb lead based paint, over six square feet per room, on this project must be RRP certified contractors and must employ proper work techniques when disturbing the lead containing surfaces.

7 1.0 Introduction AGX conducted an inspection of the Northview Pre K-8 located at 310 Mount Pleasant Road in Pittsburgh, Pennsylvania, to identify, locate and quantify asbestos-containing materials (ACM) and other hazardous materials such as: lead based paint, 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; storage tanks; stored solvents, paints, and other miscellaneous chemicals consistent with a Phase I Environmental Site Assessment. The inspection was conducted March 30, April 1, 8 and May 4, 2010 by Mr. Steven M. Corwin certified PA Asbestos Building Inspector (#029238) and Mr. Stephen Kerr, an Environmental Specialist. As part of this assessment, bulk samples were collected from accessible suspect asbestoscontaining materials and paint systems for laboratory analysis. During the writing of this report a review was made of previous credible sampling data on file at the Pittsburgh Board of Education Facilities Office and at AGX. The previous sampling data (including data from management plans) has been incorporated into this report. 2.0 Asbestos-Containing Materials (ACM) AGX conducted the inspection to identify, locate, and quantify ACM throughout the building. AGX 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 bags, given unique sample numbers, and logged with an appropriate chain of custody. The samples were analyzed by AGX, Inc., which is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP), 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. AGX identified a total of forty-two (42) homogeneous areas and collected one hundred fifty-eight (158) bulk samples of suspect ACM throughout the building. The following materials have been sampled and found to be ACM. Friable ACM Fitting Insulation on Fiberglass Insulated Lines AGX, Inc. 5

Inspectors certifications are located in Appendix E Accreditations. 3.0 Hazardous Materials Inspection 3.1 Fluorescent Lamps AGX identified approximately two thousand four hundred (2,400) mercury-containing fluorescent tubes throughout the building. AGX also identified twenty (12) high intensity lamps on the exterior of the building and in storage. The term lamp refers to mercury-containing lamps, fluorescent tubes or bulbs, metal halide, high-pressure sodium, and mercury-vapor lamps. 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 AGX, Inc. 7

10 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. AGX, Inc. 8

11 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. 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 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 assumed PCB-containing oil from the one thousand one-hundred ninety (1,190) assumed light ballasts observed throughout the school, one (1) emergency generator and two (2) air compressors located in Boiler room 123 is also found in Table 2.

12 3.3 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. AGX identified one (1) walkin cooler in the Cafeteria, one (1) chest freezer in the Kitchen, and four (4) water fountains located in the main corridors. 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. 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. Seven (7) exit signs or emergency lights which have been presumed to 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. AGX, Inc. 10

13 3.5 Mercury Mercury may be present inside thermostats, thermometers, switches and laboratory drain traps. AGX inspected select thermostats present through-out the school. All inspected thermostats appear to be pneumatic types containing no mercury. Two (2) mercury switches were identified in Boiler Room 123. No mercury containing thermometers or sink traps 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. AGX identified the following: Classrooms Containers of household cleaners Containers of household disinfectants General Purpose Cleaners Electrical Eqpt. Room Insect Killing Spray Eighteen 1 gallon cans of Paint Basement Container of Corrshield Several container of household cleaners Maintenance Room Four 5 gallon containers of gasoline Eight 5 gallon containers and 3 Drums of Pink Concentrate The estimated cost to remove and dispose of the identified chemicals is found in the following table.

Notes Cost estimates reflect 2012 unit pricing averages gained from select Pittsburgh based hazardous remediation firms. NA = Not Applicable 4.0 Lead-Based Paint (LBP) Nine (9) paint systems were sampled through-out the school from building components. Eight (8) of the nine (9) samples were analyzed as one (1) sample collected had insufficient weight to be weighed and analyzed. All of the eight (8) sampled paint systems were found to contain lead above the laboratory limit of detection, at concentrations between 0.009% and 0.031% lead by weight. All paint samples with detectable concentrations of total lead 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. Unless Child Occupied, 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). In addition the above mentioned OSHA requirements, the EPA s RRP (Renovation, Repair and AGX, Inc. 12

15 Painting) Rule will apply when the renovated facility will be Child Occupied - used by children less than 6 years of age. This means that all contractors who disturb lead based paint; over six square feet per room, must be RRP certified contractors and must employ proper work techniques when disturbing the lead containing surfaces. The samples were analyzed by RJ Lee Group, 350 Hochberg Road, Monroeville, Pennsylvania, 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. AGX, Inc. 13

16 5.0 Summary AGX performed an inspection for asbestos and hazardous materials throughout all accessible areas of the Northview PreK-8, located at 310 Mount Pleasant Road Pittsburgh, Pennsylvania. Asbestos, lead paint and hazardous materials were identified in the building and included mercury-containing light tubes, high intensity lamps and switches, potential PCB-containing equipment, potential CFC containing equipment, and miscellaneous stored chemicals. Based on the results and findings of the building inspection, AGX recommends the following: ACM that will be impacted by future 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 disturbance. Painted substrates in the school were found to contain lead. The EPA s RRP (Renovation, Repair and Painting) Rule will apply when the renovated facility will be Child Occupied - used by children less than 6 years of age. This means that all contractors who disturb lead based paint; over 6 sq ft per room, must be RRP certified contractors and must use proper work techniques when disturbing the lead containing surfaces. Painted substrates in the school were found to contain lead. In accordance with OSHA Standard 29 CFR , contractors are required to notify and train all employees involved in the construction, alteration, and/or repair of lead-containing building components, of the presence of lead. The Contractors are also required to conduct an initial Employee Exposure Assessment in accordance with 29 CFR (d) (1) (i). Prior to cutting, sanding, or welding painted structural steel for renovation or demolition, the paint should be properly abated from each structure. All hazardous materials/equipment impacted by renovation or demolition activities should be removed by properly trained contractors and/or personnel, and the materials disposed of in accordance with USEPA and Commonwealth of Pennsylvania hazardous waste regulations and guidelines. Photographs of hazardous materials and types of equipment found are located in Appendix B Photographs. 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. Unless Child Occupied, 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). AGX, Inc. 14
