1. INTRODUCTION

This document was prepared by SUMMIT Technical Resources, Inc. (SUMMIT) for Fort Carson under the U.S. Army Corps of Engineers – Omaha District, Contract No. W912DQ-12-D-3007, Delivery Order DK02. Tasks performed under this Delivery Order include completing an asbestos-containing material (ACM) inspection/survey, a lead-based paint (LBP) inspection/survey, and a hazardous materials survey at Fort Carson Military Installation (Fort Carson) Building 1218. These surveys were conducted on May 18, 19, and 28, 2015.

1.1 Intent and Limitations

The intent of these surveys was to reduce, but not eliminate, uncertainty regarding the presence of ACM, LBP, and hazardous materials in the building. Best professional practices and standard procedures were followed during these surveys to identify, within the limited extent possible in accessible areas, ACM, LBP, and/or hazardous building materials which may require removal and disposal prior to renovation or demolition of the building. The surveys were conducted in accordance with the Final Asbestos, Lead-Based Paint, and Hazardous Materials Survey Work Plan, Buildings 1117, 1218, and 1220, Fort Carson, Colorado and the final-approved Field and Laboratory Procedures Manual (SUMMIT 2011), as well as applicable federal and state regulations.

1.2 Scope of Work

The scope of work for this project included:

Perform a visual inspection to locate homogenous suspect ACM throughout the accessible areas of the building.

Collect bulk samples of materials suspected of containing asbestos and submit samples to an accredited laboratory for Polarized Light Microscopy (PLM) analysis.

Analyze painted surfaces throughout the building using an x-ray fluorescence (XRF) analyzer and record results.

Collect paint chip samples for lead content, if any as directed by the client, and submit samples to an accredited laboratory for toxicity characteristic leaching procedure (TCLP) analysis.

Locate and quantify hazardous materials, such as polychlorinated biphenyl (PCB) containing light ballasts, ozone depleting substances (such as in air conditioning units), mercury-containing fluorescent light tubes, and mercury-containing switches/thermostats.

Provide a written report summarizing the findings of the bulk sampling, XRF analysis, paint chip analysis (if any), and hazardous materials inventory.

Provide recommendations for removal of materials, and areas which will require further inspection and sampling, as necessary, prior to demolition or renovation.

Section 1 – Introduction

SUMMIT Technical Resources, Inc. 1-2 Asbestos-Containing Material, Lead-Based Paint, and Hazardous Materials Surveys Completion Report Building 1218

1.3 Inspection Summary

The results of the survey found that ACM, LBP, and hazardous materials exist in the building which will require removal and proper disposal prior to any demolition or renovation activities.

Further investigation and sampling of suspect ACM may need to be completed by a Colorado Asbestos Building Inspector (CABI) if other suspect materials not identified by this survey are discovered during renovation/demolition activities. Additional paint samples may need to be collected by a Colorado Lead Based Paint Inspector, to determine actual lead content in the paint for disposal purposes. Additional hazardous materials (not ACM/LBP) may exist in inaccessible areas, and should be properly identified, removed, and disposed, as necessary, prior to signing required permits. There is no guarantee, spoken or implied, that all ACM, LBP, and hazardous materials have been identified in the survey. Therefore, SUMMIT, and its subcontractors, cannot be held accountable for unknown conditions, restrictions from the client, or complete coverage of other inaccessible areas at the time the surveys were conducted. The findings and conclusions of the surveys are based on conditions observed during the site visits.

Appendix A includes all field forms generated during the surveys. Appendix B includes analytical data and chain-of-custody (COC) forms. Photographic logs for the lead-based paint survey and hazardous materials survey are included in Appendix C. State of Colorado Certifications are included in Appendix D.

SUMMIT Technical Resources, Inc. 2-1 Asbestos-Containing Material, Lead-Based Paint, and Hazardous Materials Surveys Completion Report Building 1218

2. BUILDING USE AND CONSTRUCTION

Building 1218 was constructed in 1958 as a barrack, but is currently used as office space. It is a three-story, permanent structure with a total building area of approximately 52,000 square feet (sqft). The exterior walls are constructed of brick, and interior wall construction consists of gypsum wallboard and/or concrete masonry units (CMU). The roofs are built-up, multiple layer tar and gravel surfacing.

At Building 1218, a re-inspection was conducted in 1991 by Occupational Health Technologies, Inc. The 1991 survey identified the following materials as asbestos containing: brown speckled 12-inch by 12-inch floor tile and mastic in the Mess Hall; mastic beneath all other floor tile; and TSI joints. A second re-inspection was completed by Family Environmental Compliance Services, Inc. in 2000. The 2000 survey identified approximately 50,000 sqft of mastic and 19,500 sqft of roof flashing as asbestos containing. In 2009, approximately 5,000 sqft of tile and mastic, and three asbestos fittings were removed from the 1st floor in the main north center dining and kitchen area. An asbestos update completed in 2008 indicated that the 19,500 sqft of asbestos-containing roof flashing remained in the building, along with 45,000 sqft of tile and mastic on all three floors. The update also identified TSI fittings inside the walls throughout the building as possibly containing asbestos.

3. ASBESTOS-CONTAINING MATERIALS SURVEY

SUMMIT conducted an asbestos survey at Fort Carson Building 1218 during May 18, 19, and 28, 2015. The building was occupied during the survey, therefore, non-destructive sampling techniques were used in order to mitigate potential exposure to occupants and minimize visible damage. Various materials were unable to be sampled such as pipe insulation behind walls, roofing materials, and fire doors, and inaccessible areas (e.g. within walls, pipe chases, etc.) were not inspected or sampled due to the non-destructive nature of the survey.

3.1 Methodology

Materials within the building were physically inspected, functional space-by-functional space, and homogeneous area by homogeneous area, to determine the potential presence of ACM.

Suspect materials uniform in texture and color were grouped together as homogeneous materials.

Materials which did not appear to be uniform in texture or color, or were suspected of being of different from surrounding materials, were identified as separate homogeneous materials. A bulk sampling plan was developed in the field based upon the type and quantity of homogeneous, suspect materials. A bulk sampling plan determined the appropriate location and quantity of samples to be collected. Each homogenous, suspect material was quantified and characterized by condition and friability (able to crumble with hand pressure). Samples of suspect materials were collected as required by the U.S. Environmental Protection Agency (USEPA) Final Rule.

Bulk samples were randomly collected from each homogenous area of suspect building materials and placed in the following categories:

Thermal System Insulation (TSI) - wrap or insulation on various building system pipes and fittings, inside ducts, etc.

Surfacing materials - materials that are toweled on or sprayed on surfaces such as plaster, texture, mortar, mastic, joint compound/wall mud, floor level, etc.

Miscellaneous - all remaining material that do not include TSI or surfacing material such as floor tile, ceiling tile, transite siding, transite pipe, gaskets, felts, etc.

For surfacing materials, the following sampling USEPA-required protocol was followed:

A minimum of three bulk samples were collected from each homogenous area that is 1,000 sqft or less.

A minimum of five bulk samples were collected from each homogenous area greater than 1,000 sqft but less than or equal to 5,000 sqft.

A minimum of seven bulk samples were collected from each homogenous area greater than 5,000 sqft.

At least one sample was collected from each suspected miscellaneous material. At least three samples were collected from each homogeneous area of TSI with the following exceptions:

SUMMIT Technical Resources, Inc. 3-2 Asbestos-Containing Material, Lead-Based Paint, and Hazardous Materials Surveys Completion Report Building 1218

TSI in general - three samples.

Less than 6 linear ft or sqft of patch - 1 sample.

Elbow/fittings and cementaceous material - sufficient to determine asbestos content.

Samples were submitted to EM Lab P&K - an accredited laboratory which is a subsidiary of TestAmerica - and analyzed by PLM using USEPA Method 600/R-93/116. Samples which were determined to have less than 2% asbestos by PLM were point counted by USEPA 400 point count (USEPA Method 600/R-93/116).

All work was performed in accordance with the USEPA, National Emission Standards for Hazardous Air Pollutants (NESHAP), Occupational Safety and Health Administration (OSHA), and the Colorado Department of Public Health and Environment (CDPHE) regulations, specifically the CDPHE Air Quality Control Commission Regulation 8, Part B, Emission Standards for Asbestos (5 Code of Colorado Regulations [CCR] 1001-10.

3.2 Inspection Results

Laboratory analysis of bulk samples, and visual and tactile assessment of materials, confirmed the presence of asbestos in Building 1218. Materials with asbestos concentrations found to be greater than 1% asbestos and materials assumed to contain asbestos include the following:

12”x12” floor tile and black mastic

Pipe sealant and TSI fittings throughout

Exterior caulking on windows, doors, and rooftop vents

Inaccessible materials inside tunnel in Boiler Room (assumed)

Floor Tile – 0.5-0.75% Chrysotile. Black Mastic – 2-5% Chrysotile. Non friable. Homogenous Areas 45, 46, 47.

Asbestos was identified in various 12x12 floor tile and black mastic on the second floor. The floor tile samples were point counted and the results were all below 1% ACM, however, the associated black mastic has asbestos greater than 1%. Therefore, it is assumed that all second floor 12x12 tile and its associated black mastic contain asbestos.

Locations on the second floor that do not have ACM floor tile or mastic:

Men’s and Women’s Restrooms: original ceramic floor tiles

Mechanical Rooms and Storage Rooms: cement

Stairway and Elevator Rooms: flooring, tile, and cream mastic was non-detect for asbestos on all 3 floors

Carpet covers most of the third floor (excluding storage rooms, Mech rooms, restrooms). Random spot inspections were performed throughout. Floor tile with tan mastic was discovered underneath. Black mastic and tile taken in the doorway between Room 303B and the hallway were found to contain asbestos. Due to the fact that random inspections did not identify black mastic with the exception of the hallway, it is possible for asbestos-containing mastic to be present in areas which were not visually inspected. Based on the visual inspections performed, it is believed that likely only minimal areas will have asbestos-containing mastic. Further investigation is recommended once the area is not occupied.

Sample Numbers: B1218-243, B1218-244, B1218-245, B1218-248

TSI Fittings and Pipe Sealant – 2-5% Chrysotile. Friable.

Laboratory results indicate that asbestos-containing homogeneous pipe sealant and TSI fittings exist in areas throughout the building. During the investigation, these pipe fittings were identified, but not limited to, the following areas:

Mechanical Rooms on each floor

Room 166

Main Boiler Room (excluding TSI in the crawl space)

Boiler Room Tunnel (assumed)

2nd Floor Rooftop Mech Room

Some samples tested positive, and others negative, that were determined to be in the same homogenous group.

The difference between non-ACM and ACM sealant and fittings is not able to be determined during this non-destructive survey. Therefore, all pipe sealant is considered ACM. Additionally, further sampling may occur once the building is under construction when more pipe systems can be discovered.

The non-friable pipe sealant is located on fiberglass insulation throughout the building. Some sealant appears to be newer, and none detected for asbestos. However, there is ACM sealant on pipes throughout the building. We recommend additional testing once the area is unoccupied to determine the non-ACM systems from the ACM systems. Additionally, friable TSI fittings were identified in areas throughout. We have assumed that both ACM sealant and fittings to exist on pipe runs throughout the building.

A thorough building walkthrough with a licensed abatement contractor is recommended to identify locations and quantities of the pipe runs, chases, and wall cavities to determine the appropriate abatement protocols to remove all TSI which will be exposed and or impacted during renovations. See Figures 3-6 through 3-6 for detected locations of asbestos containing TSI fittings and pipe sealant identified during this investigation.

Please note the TSI may be damaged, and may be present lying on the ceiling tile, and within the wall cavities

SUMMIT Technical Resources, Inc. 3-11 Asbestos-Containing Material, Lead-Based Paint, and Hazardous Materials Surveys Completion Report Building 1218 and pipe chases. Assume pipe chases with ACM sealant on many pipes exist in the building. All areas with known TSI should be treated as a minor spill so as to not allow asbestos fibers to migrate into adjacent areas.

Recommend material removed prior to renovation/demolition: Yes. Remove or repair all damaged TSI Fittings that will not be disturbed. Remove all TSI that will be disturbed during renovations.

Exterior Caulking – Around doors, windows, and rooftop vents.

Exterior Caulking – 3-5% Chrysotile. Non friable. Homogenous Areas 89, 90, 94, and 105.

The caulking found on the exterior of the building is positive for asbestos and non-friable, however, is considerably loose and weathered in some locations. Also, the material may be rendered friable during demolition and/or renovation. It is recommended that the damaged caulking around the windows, doors, and vents be properly removed and disposed of by a certified GAC and all impacted caulking be properly removed of and disposed of in accordance with applicable regulations.

During the investigation, exterior ACM-caulking was surrounding the following items:

Table 3-1 presents a detailed description of all the samples collected during the asbestos survey activities. Figures 3-1 through 3-5 show all sample locations and detections of asbestos above 1%. Figures 3-6 through 3-10 show homogenous locations where abatement is recommended.

The laboratory analytical reports and COCs are included in Appendix B.

3.2.1 Further Inspection Details

The following items were observed during the investigation:

The tunnel in the Boiler Room was inaccessible due to a pipe across the opening.

Samples taken of the pipe insulation and wrap at the opening of the tunnel were determined to be non-detect for asbestos. However, the materials not sampled inside of the tunnel are assumed to be ACM and should be visibly verified and/or sampled by a CABI prior to disturbance.

To maintain structural integrity, roofing materials were not able to be sampled. If the roof is to be disturbed during renovation, samples should be taken to determine all roof ACM locations and materials.

Tile, mastic, and surfacing in homogenous stairwells and elevator rooms were found to be non-detect, and should be treated separate from the results from individual floors.

3.2.2 Assumptions

The following building materials are assumed to contain asbestos and were not sampled to protect structural integrity or because a material was not accessible.

Inaccessible materials inside tunnel in Boiler Room

Fire doors

Inaccessible caulking material

Materials inside elevator shaft

Transite pipe underground - Fort Carson is known to have transite pipe underground. If performing a demolition at this building, use caution when digging.

Roofing materials – drain gaskets, tar, inaccessible caulking, etc.

If these assumed materials are to be disturbed during renovation, they should be sampled by a State of Colorado CABI prior to renovation/demolition activities to confirm the presence or absence of asbestos.

SUMMIT Technical Resources, Inc. 3-13 Asbestos-Containing Material, Lead-Based Paint, and Hazardous Materials Surveys Completion Report Building 1218

3.3 Recommendations

Floor tile and black mastic - The black mastic and floor tiles, which were positive for asbestos, are non-friable and are considered to be good to fair condition. The USEPA and CDPHE allow non-friable ACM to remain in a facility during demolition, and the material may be disposed of with other general demolition debris at a solid waste landfill. The material must remain non-friable and demolition cannot be conducted by means of cutting/grinding/abrading, burning, or using explosives. If the floor tile and/or mastic will be disturbed during renovation activities, it is recommended that the material be properly removed and disposed by a certified General Abatement Contractor (GAC) prior to renovation or demolition.

TSI Fittings and Pipe Sealant - A thorough building walkthrough with the abatement contractors is recommended to identify locations of the pipe runs, chases, and wall cavities to determine the appropriate abatement protocols to remove all TSI which will be exposed and or impacted during renovations. Please note that the TSI may be damaged, and therefore pieces may be lying on top of ceiling tiles and/or within the wall cavities and pipe chases. All areas with known TSI should be treated as a minor spill so as to not allow asbestos fibers to migrate into adjacent areas.

Caulking - The caulking found on the exterior windows, doors, and 2nd floor vents throughout the building is positive for asbestos and non-friable; however, it was observed to be loose and weathered in some locations. Also, the material may be rendered friable during demolition and/or renovation. It is recommended that the caulking be properly removed and disposed of by a certified GAC prior to demolition or renovation.

Assumed materials including fire doors, inaccessible caulking material, roofing materials, roof drain gaskets, rope gaskets between roofing panels, and underground transite piping were not sampled to maintain structural integrity or due to inaccessibility. These materials are assumed to contain asbestos and should be investigated and sampled by a CABI if disturbed during renovation activities.

A demolition permit is required by CDPHE for all demolition activities, to include burning, even if a building does not contain asbestos. A demolition permit is also required for remodeling activities that involve the destruction or removal of a load-supporting structural member. The permit would require the identification and removal of any ACM to be disturbed during renovation or demolition prior to commencement of such activities.

OSHA regulation requires that workers be protected from exposure to asbestos from disturbance of otherwise non-regulated materials. The use of engineering controls and personal protective equipment is required to provide adequate protection when disturbing asbestos materials. A Negative Exposure Assessment (NEA) should be performed on any employees who will be working on the demolition or renovation of the building. A NEA consists of collecting personal exposure air samples from workers during demolition activities that disturb ACM. Workers are also required to have asbestos awareness training.

3.4 Estimated Removal Costs

A thorough building walkthrough with a certified abatement contractor is recommended in order to identify all ACM locations and to determine the appropriate abatement protocols to remove identified ACM. Actual costs may vary depending on the landfill, contractor, or whether the material can be recycled instead.

Section 4 – Lead-Based Paint Survey

SUMMIT Technical Resources, Inc. 4-1 Asbestos-Containing Material, Lead-Based Paint, and Hazardous Materials Surveys Completion Report Building 1218

4. LEAD-BASED PAINT SURVEY

The LBP survey was conducted May 18 -19, 2015. The inspection included the following tasks:

1. Visually determining the location and extent of accessible suspect LBP/ LCP.

2. Utilizing an XRF unit to determine the presence or absence of LBP/LCP.

3. Documenting the condition of LBP/LCP.

4. Collecting samples for disposal/waste characterization sampling for TCLP lead analysis.

5. Identifying all XRF reading locations, along with the positive or negative results, and bulk sample locations on an appropriate diagram.

6. Preparing field documents (Daily Log, Lead Paint Survey Field Data Sheet, Instrument Calibration Log, and COC), which are included in Appendix A.

7. Compile a photographic log of suspect LBP (Appendix C).

4.1 Methodology

Painted surfaces were analyzed using an Olympus innov-x hand-held XRF (serial # 8131) spectrum analyzer that produces results for lead content. Calibration checks were performed at the beginning and end of the inspection and at least every four hours during the inspection.

Calibration was verified against known lead samples produced by the National Institute of Standards and Testing (NIST) Standard Reference Material (SRM) 2573 lead paint film (1.040 milligrams per square centimeter [mg/cm2] color code red). The inspection was conducted in accordance with industry standards and regulatory protocols. The Housing and Urban Development (HUD) standard of 1.0 mg/cm2 of surface area was used to determine positive and negative results for LBP.

All work was performed in accordance with USEPA and OSHA protocols, CDPHE regulations, specifically the CDPHE Air Quality Control Commission Regulation 19, The Control of Lead Hazards (5 CCR 1001-23).

4.2 Inspection Results

Based on the LBP screening using the Olympus innov-x hand-held XRF, seventeen surfaces contain concentrations of LBP at a level above the HUD standard of 1.0 mg/cm2 of surface area or 0.5% by weight, and are included in Table 4-1.

As shown on Figure 4-1, a total of six surfaces tested positive for LBP on the main level exterior, basement mechanical room and first floor of the building. There were two positive detections on the CMU block with white paint on the west wall of the west wing, first floor corridor. The white paint on the CMU block of the east wall of the east wing, first floor corridor also had one positive detection for LBP. A round metal support pole located in the Westside mechanical room was positive for LBP. The red paint on CMU block in room 110 was also positive for LBP. The white paint on the CMU block on the north wall of room 123 was positive.

SUMMIT Technical Resources, Inc. 4-2 Asbestos-Containing Material, Lead-Based Paint, and Hazardous Materials Surveys Completion Report Building 1218

A total of three surfaces tested positive for LBP on the second floor and interior stairwells (Figure 4-2). There was a positive detection for LBP on the white painted CMU blocks on the east wall of the east wing in the second floor corridor. The metal railing with brown paint located in the east stairwell was positive for LBP. A metal angle iron that appeared to be bracing the CMU block in the second floor corridor also tested positive for LBP.

As shown on Figure 4-3, a total of eight surfaces tested positive for LBP on the third floor.

Three positive detections on the white paint on the west wall of the west wing of the corridor.

Another two locations were positive for LBP on the east wall of the east wing of the corridor.

The remaining three positive detections were on small buff colored glazed blocks located in the men's restroom and rooms 341 and 319.

4.2.1 Assumptions

Like painted surfaces in each area/floor were assumed to be homogenous; therefore, the following painted surfaces are assumed to contain LBP.

The white paint on CMU block and concrete supports on the east wall of the east wing of the first, second, and third floor corridors.

The white paint on CMU block and concrete supports on the west wall of the west wing of the first, second, and third floor corridors.

The hand rails located in both stairwells.

The small glazed block painted or unpainted located on the first, second, and third floor restrooms and rooms 341 and 319. (Appendix C: photos 11 and 40).

The red and white paint on the CMU block walls in rooms 110 and 123.

The white paint on the metal support pole in both the east and west side mechanical rooms on the first, second, and third floors.

All silver foil like metal on the roof vents located on the roof. The silver foil like metal covering the roof vents has tested positive on similar buildings and was assumed on building 1218.

Lead pans under showers in the restrooms on the first, second, and third floor.

It should be noted that none of the seventeen positive LBP surfaces had concentrations exceeding

5.0 mg/cm2. Any detection greater than 5.0 mg/cm2 exceeds regulatory limits for demolition waste and per direction of the Fort Carson Directorate of Public Works (DPW) no samples were collected for TCLP analysis as destructive sampling was not permitted by DPW at the time of inspection due to the continued use of the building by employees.

4.3 Recommendations

With respect to the intended demolition and/or renovation of this building, recommendations for LBP largely depend upon the current occupancy/use of the facility and/or intended future use of

SUMMIT Technical Resources, Inc. 4-3 Asbestos-Containing Material, Lead-Based Paint, and Hazardous Materials Surveys Completion Report Building 1218 the facility. The following is an overview of regulatory requirements for demolition and/or renovation in relation to LBP:

Non-household generators of lead-contaminated waste must make a hazardous waste determination prior to disposal. Lead-bearing waste must be managed as either a solid waste or a hazardous waste depending upon the results of TCLP tests for lead. The TCLP maximum contaminant concentration for lead is 5.0 milligrams per liter [mg/L] (5.0 parts per million [ppm]). Wastes with 5.0 ppm or greater lead content by TCLP exhibit the toxicity characteristic for lead and must be managed as a hazardous waste.

In instances where the underlying media/substrate of LBP is metal, such as the metal door frames, hand rails, etc., the LBP can be removed with solvent in small sections to allow for cutting and removal of these items, and the entire piece can be sent for metals recycling. The demolition/renovation contractor should make every attempt to recycle as many materials as reasonably possible to save costs and minimize wastes going to landfills.

If the waste consists of demolition debris, the appropriate way to collect samples for analysis is by coring a representative portion of the material to be disposed (i.e. core through the wall, including both paint and wood). Because of the relatively small amount of lead present in the paint film on a wall, these wastes may not fail the TCLP test and can be disposed of as solid waste. If the material to be disposed only includes lead-based paint chips, sludge, or blasting wastes, they will often fail the TCLP test due to having concentrated lead in the material. All wastes that fail the TCLP test must be disposed of as hazardous waste.

Under Colorado’s hazardous waste regulations, electronics wastes from non-household sources must be managed as hazardous or universal wastes and are prohibited from disposal in solid waste landfills. Refer to the Division’s compliance bulletin on the management of electronics wastes for information on proper management.

4.4 Estimated Removal Costs

The unit costs provided herein are industry costs found from various sources and are provided for informational/internal estimating purposes only. Actual costs may vary depending on the landfill, contractor, or whether the material can be recycled instead.

The amount of LBP at Building 1218 could not be easily quantified due to the varying surface areas of the media it covered. However, removal costs for LBP range from $8 to $12 per square foot. The demolition/renovation contractor should quantify the final amount of material to be removed prior to demolition/renovation. Additionally, as stated above, recycling options are available as opposed to disposal as a hazardous waste to a landfill.

Section 5 – Hazardous Materials Survey

SUMMIT Technical Resources, Inc. 5-1 Asbestos-Containing Material, Lead-Based Paint, and Hazardous Materials Surveys Completion Report Building 1218

5. HAZARDOUS MATERIALS SURVEY

The hazardous materials survey was conducted May 18 & 19, 2015. The inspection included the following tasks:

1. Visually determining the extent and location of accessible suspect hazardous materials;

2. Documenting the type, condition, and quantity of suspect hazardous materials;

3. Identifying all suspect materials on an appropriate diagram; and

4. Preparing field documents (Daily Log), which are included in Appendix A.

5. Compile a photographic log of potentially hazardous materials (Appendix C).

5.1 Methodology

The hazardous materials survey consisted primarily of inventorying any and all interior/exterior fixtures that may contain hazardous substances. These include, but are not limited to, lighting components (mercury vapor lights and/or PCB ballasts), refrigeration/air conditioning equipment containing ozone depleting substances, exit signs containing a low grade radioactive source, and various fixtures containing lead (not LBP).

The hazardous materials survey was performed with limited removal or disassembly of the indoor fixtures. Fluorescent light assemblies that were easily accessible where opened to identify what type bulb and ballast is housed within the assembly. Both exit signs and flood lights were inspected without removing them from the wall and upon inspection no discernible manufacture markings were identified on the outside of the housings other than manufacture name. In addition to the fixture noted above any paints, solvents, flammable substances, or any items that could potential cause harm to maintenance personal was inventoried.

All work was performed in accordance with USEPA, OSHA, and CDPHE protocols.

5.2 Inspection Results

Various indoor fixtures in Building 1218 were identified as having the potential to contain hazardous materials. While not regulated as hazardous materials while functioning under their intended use within the building, the materials listed below are potentially regulated as hazardous, universal, or other special wastes upon removal from the building and disposal, and should not be included in demolition debris that is disposed of at a landfill or recycled.

Electronic ballasts were largely identified in the fluorescent light fixtures throughout building 1218. Additionally, 5 transformer ballasts were observed throughout the building. The quantities of both flood lights and exit signs were also inventoried. However, the manufacturer and model numbers were not collected due to no discernible manufacture markings located on the outside of the housing. No units were removed from their locations and inspected for manufacture marking on the backside of the mounting plates. As noted on Table 5-1, the lighting fixtures on the third floor were observed to have battery backups, a total of 17 flood lights were only observed, and 23 exit signs were observed throughout Building 1218. The flood lights appeared to be connected to the electrical system and therefore likely contain rechargeable battery such as a NiCad battery. Because the emergency exit signs were only inspected on the outside, the presence of tritium batteries could not be verified.

5.3 Recommendations

Under a demolition/remodel scenario, all items noted above should be removed from Building 1218 and properly disposed of. The items should not be included in demolition debris that is disposed of at a landfill or recycled. Disposal of hazardous, universal, or special wastes shall be coordinated with DPW. All work should be conducted in accordance with the Occupational Safety and Health Administration guidelines for protection of personnel.

The emergency exit signs should be further inspected to determine the presence or absence of tritium batteries. Any signs which do not contain radioactive power sources can be disposed as general trash. Signs with tritium batteries must be disposed as hazardous waste in accordance with State and federal regulations. For the purposes of this survey, all emergency exit signs are assumed to contain tritium batteries.
