EXECUTIVE SUMMARY

As part of the Architect of the Capitol (AOC) Statement of Work for Thurgood Marshall Federal

Judiciary Building (TMFJB) Security Program Upgraded, Apex Companies, LLC (Apex) conducted a building inspection for asbestos-containing materials (ACM), lead-based paint (LBP), polychlorinated biphenyl (PCB) suspect sealants and other hazardous materials. Inspection services were performed in

February 2019. The building inspection was limited to interior and exterior Security Program Upgraded areas (project areas) only.

Asbestos Inspection

Accessible interior and exterior project areas of the subject property were inspected for ACM. Apex conducted the asbestos inspection using guidelines set forth by the Occupational Safety and Health

Administration (OSHA) and the U.S. Environmental Protection Agency (EPA). ACM is defined by federal and the District of Columbia regulations as a material that contains greater than one (1) percent asbestos by laboratory analysis.

Mr. Daniel Admasu and Mr. Peter Braun conducted the on-site inspection and are EPA-accredited asbestos inspectors. A copy of Mr. Daniel Admasu’s and Mr. Peter Braun’s certifications can be found in

Appendix A. Laboratory analytical results confirmed the following materials to be ACM:

Based on laboratory analysis results, none identified to be ACM.

The following material was assumed to be ACM that was not readily encountered or accessible for sampling during our site visit:

Fire rated doors in Daycare, Fire Command office, Stairwells, and perimeter walls.

Lead Inspection

Accessible interior and exterior project areas were inspected for LBP. Apex conducted the lead inspection by using a portable x-ray fluorescence (XRF) analyzer. The current definition of LBP established by the District of Columbia is greater than or equal to 1.0 milligrams of lead per square centimeter of surface area (≥ 1.0 mg/cm2) by XRF sampling.

Apex’s on-site XRF lead-based paint inspection revealed none to be above the District of

Columbia’s definition for LBP.

QuinnEvans-TMFJB-HazMatInsp_rpt;(QUINN-023);dta/ttn iv

Apex notes that detectable levels of lead below the District of Columbia’s definition of LBP were reported in paint on multiple building components. Work practices involving the disturbance of such lead-containing paints or other materials are regulated under the OSHA’s Lead in Construction Standard in Title

29 of the CFR Part 1926.62. As a result, all construction and demolition activities involving lead-containing materials (regardless of the lead content) must comply with the OSHA standard, which prescribes requirements for contractor/worker exposure assessment, worker protection, and engineering controls.

Other Hazardous Building Materials

As part of Apex’s scope of work, Apex inspected for other potential hazardous building materials, such as mercury-containing lighting tubes, thermostats and gauges, polychlorinated biphenyl (PCB) light ballasts and transformers, etc. A summary of Apex’s findings is presented below.

Mercury Hazards

No mercury containing comments will be impacted within the project area. Any concealed building materials discovered during renovation/demolition activities, which are suspected to contain mercury should be investigated or tested to confirm the absence or presence of mercury.

PCBs (Polychlorinated Biphenyls)

Polychlorinated biphenyls (PCBs) suspect materials such as caulking, sealant and expansion joints were assessed in the project areas during the site visit. Results of the laboratory analysis confirmed none for the presence of PCB’s in all samples analyzed.

1.0 ASBESTOS INSPECTION

Apex conducted the asbestos inspection of the building using guidelines set forth by the

Occupational Safety and Health Administration (OSHA) and the U.S. Environmental Protection Agency

(EPA).

Materials that were considered suspect were identified and the number of samples to be collected of these suspect materials was determined by the inspector using the Asbestos Hazard Emergency

Response Act (Title 40 CFR Part 763) (AHERA) protocols. As defined by AHERA policy, suspect materials include the following building material types:

1. Surfacing Materials – including spray-applied or troweled-on wall/ceiling coatings;

2. Thermal System Insulation (TSI) – including pipe insulation, and mudded pipe elbows, and;

3. Miscellaneous Materials –including ceiling tile, floor tiles and mastics, gaskets (if accessible), fire doors, wallboard and spackling.

Suspect materials that are homogeneous in nature (i.e., uniform in color and texture) were identified, touched to determine friability, and sampled by removing a small piece that was then placed in a labeled container. For a given homogeneous area, one (1) or more samples were collected in a randomly distributed manner in accordance with AHERA provisions as referenced in the OSHA Asbestos in

Construction standard (Title 29 CFR 1926.1101). Materials not considered by the AHERA standard as suspect ACM were not addressed by Apex during this inspection, unless specifically referenced.

Table 1 contains a list of the confirmed ACM. The information provided in this table includes detailed ACM descriptions, friability (ability to be reduced to powder by hand pressure), locations, and approximate quantities. Table 2 contains a list of homogeneous materials sampled; which provides a complete list of all identified suspect ACM. Each suspect material is grouped according to class (i.e., surfacing, TSI, or miscellaneous material). This table provides descriptions of each suspect ACM, general location, friability, samples collected, and ACM determination.

All bulk samples were sent to EMSL Analytical, Inc., of Cinnaminson, NJ, a National Voluntary

Laboratory Accreditation Program (NVLAP) accredited laboratory and analyzed using polarized light microscopy in conjunction with dispersion staining (PLM/DS) to determine asbestos content. Appendix B contains the laboratory results/chain-of-custody for all bulk samples collected by Apex during the asbestos inspection.

QuinnEvans-TMFJB-HazMatInsp_rpt;(QUINN-023);dta/ttn 2

1.1 Sampling Protocol

Suspect building materials to be sampled were classified as friable or non-friable (as defined by the EPA). The materials were sampled to determine whether they are asbestos-containing [i.e., contain greater than one (1) percent asbestos]. Samples were analyzed for asbestos content using PLM/DS by a NVLAP accredited laboratory.

Suspect materials were sampled in general accordance with EPA's AHERA, as referenced in the most recent (September 1996) revision of the OSHA's Asbestos in Construction regulations

[Title 29 of the Code of Federal Regulations (29 CFR) 1926.1101], as follows:

MODIFIED AHERA SAMPLING PROTOCOL

Type of Material Estimated Quantity Required Samples

Sprayed or Troweled-on Surfacing Material

Greater than 5,000 ft2 7

Between 1,000 ft2 and 5,000 ft2 5

Less than 1,000 ft2 3

Thermal System Insulation All Quantities 3

Miscellaneous Materials All Quantities

Per AHERA, these materials must be sampled "in a manner sufficient to determine whether or not they contain asbestos." Apex generally collects 1 to 3 samples of such material based upon the inspector's judgment.

Note: These sampling protocol quantities are per functional area and/or homogeneous area.

A number of suspect ACM identified at the building warranted special scrutiny or otherwise required special consideration. These materials are:

• Floor tiles, resilient flooring, and mastics: All floor tiles, resilient flooring, and underlying mastics were considered suspect ACM. Each flooring material and its associated mastic were sampled and analyzed separately. If either component was found to contain greater than one (1) percent asbestos, then only that material was considered ACM. If carpeting was affixed to the floor, Apex’s procedure consisted only of pulling corners up to one (1) foot to view the material beneath. Based on this observation, the characterization of the homogeneous material underneath (i.e., tile or mastic), if any, was extrapolated to the entire floor surface of that area. Note: When only the mastic tests positive as ACM, the floor tile should also be considered as ACM due to residual mastic that remains on floor tile during removal.

2.0 LEAD BASED PAINT INSPECTION

Apex performed an x-ray fluorescence (XRF) lead-based paint (LBP) inspection of the project areas. The purpose of the inspection was to determine if LBP is present on the building components located within the interior project areas, which may be directly affected during the course of renovation activities.

The XRF LBP inspection was performed utilizing XRF spectrum analyzer to determine the presence of suspect lead-painted components. XRF technology is well known for accuracy in detecting lead within individual layers of paint. By emitting radiation through each paint layer, Apex was able to determine the presence of lead within tested components. Building components typically known for posing potential lead exposure were tested during the inspection. All XRF test results are found in Table 3.

Certain rooms/areas of the building, similar in design and construction history, were included within the representative LBP inspection. The current definition of LBP established by the District of Columbia is greater than 1.0 milligrams of lead per square centimeter of surface area (>1.0 mg/cm2) using a portable

XRF analyzer.

Apex’s on-site XRF lead-based paint inspection revealed none to be above the District of

Columbia’s definition for LBP.

The lead paint testing is intended to provide testing data to employers, as required by OSHA, so that measures may be taken to prevent lead exposures to workers during renovation and/or demolition activities. This inspection does not include risk assessment of lead hazard. It is important to note that even low concentrations of lead in paint (i.e., less than 1.0 mg/cm2) that do not meet the District of Columbia’s definition for LBP, have the potential to result in some lead exposure to building occupants and/or workers, particularly construction workers involved with activities such as torch cutting and welding metal structures, abrasive blasting, or sanding painted surfaces. Work practices involving the disturbance of such lead-containing paints or other materials are regulated under the U.S. Occupational Safety and Health

Administration’s (OSHA’s) Lead in Construction Standard in Title 29 of the CFR Part 1926.62. As a result, all construction and demolition activities involving lead-containing materials (regardless of the lead content) must comply with the OSHA standard, which prescribes requirements for contractor/worker exposure assessment, worker protection, and engineering controls.

3.0 OTHER HAZARDOUS BUILDING MATERIALS

Apex inspected for other potential hazardous building materials within the project areas. The purpose of the inspection was to determine if other hazardous building materials such as mercury-containing lighting tubes, thermostats and gauges, PCB light ballasts and transformers, etc. are present, which may be directly affected by the course of renovation/demolition activities. A summary of Apex’s findings is presented below.

Mercury Hazards

No mercury containing comments will be impacted within the project area. Any concealed building materials discovered during renovation/demolition activities, which are suspected to contain mercury should be investigated or tested to confirm the absence or presence of mercury.

PCBs (Polychlorinated Biphenyls)

Apex collected two (2) exterior sealant/caulk bulk samples from the west and south entrance areas to determine if PCBs were present at levels or above 50 parts per million (ppm). The samples were sent to

EMSL Analytical Laboratory of Cinnaminson, NJ for analysis by gas chromatography in accordance with

U.S Environmental Protection Agency (EPA) Test Methods (SW-846) for evaluating PCB. The samples were analyzed for Aroclors1016, 1221, 1232, 1242, 1248, 1254, 1260, 1262, and 1268 (Aroclors are multi-component mixtures of PCBs). Results of the laboratory analysis confirmed none for the presence of PCB’s in the samples.

The sampling results are summarized in Table 4. Laboratory results and chain of custody are included to this report in Appendix C. Site Photographs and Drawing are included in Appendix D and

Appendix E, respectively.

4.0 RECOMMENDATIONS

The following is a series of recommendations that Apex proposes based on laboratory analysis and conditions of the building at the time of the inspection.

Asbestos

Materials suspected of potentially containing asbestos were identified during the inspection and sampled for asbestos content. Since ACM is present in the building, actions should be taken to prevent fiber release and to minimize exposure of subcontractors to asbestos fibers. Appendix D contains a photo log of observed ACM. The following are Apex’s recommendations for management of these ACM.

• The fire doors found in the Daycare, stairwells, fire command office and perimeter areas may be impacted during construction work. Remove projected impacted doors or present a workplan addressing proper handling of asbestos containing fire doors during components removals and replacement.

• The renovation/demolition contractor and other subcontractors working within the building should be made aware of the locations of the ACM and the possibility of concealed suspect ACM that could be found during renovation activities. They should be advised to not disturb the identified ACM or suspect ACM.

• Any concealed building materials discovered during renovation/demolition activities, which are suspected to contain asbestos, should be sampled by a licensed asbestos inspector and analyzed by NVLAP-accredited laboratory to confirm the absence or presence of asbestos prior to disturbing such materials. If the materials are found to contain asbestos, applicable local, state and federal regulations will apply.

The following recommendations should be followed for demolition/renovation projects including contracting the services of an environmental consultant to monitor/document that the abatement contractor activities comply with abatement specifications, applicable local, state and federal requirements.

Using this report as a guide:

• The prospective abatement contractor(s) should independently verify quantities of ACM present and unique site conditions in order to prepare a cost estimate and for notification purposes.

Notification to the proper agency should be submitted prior to commencing any abatement activities.

• A licensed asbestos abatement contractor must remove any regulated ACM (RACM) within the District of Columbia. Abatement activities must be performed in compliance with the abatement specification, applicable local, state, and federal requirements.

QuinnEvans-TMFJB-HazMatInsp_rpt;(QUINN-023);dta/ttn 12

• A ten (10)-day working day notification to the Department of Energy & Environment (DOEE) and a thirty (30) day occupant notice is required (If occupied) on NESHAP sized (greater than or equal to 160 square feet, 260 linear feet, or 35 cubic feet) asbestos abatement projects. Additionally, three

(3) days prior to the beginning of any abatement activities, post warning signs on the entrances/exits of the building.

Lead-based Paint

• No lead abatement is required prior to demolition. It is important to note that even low concentrations of lead in paint (i.e. less than 1.0 mg/cm2) that fall below the criteria for LBP, have the potential to result in some lead exposure to workers, particularly construction workers involved with activities such as torch cutting and welding metal structures, abrasive blasting, or sanding painted surfaces. Work practices involving the disturbance of such lead-containing paints or other materials are regulated under the OSHA’s Lead in Construction Standard in Title 29 of the CFR Part 1926.62. As a result, all construction and demolition activities involving lead-containing materials (regardless of the lead content) must comply with the OSHA standard, which prescribes requirements for contractor/worker exposure assessment, worker protection, and engineering controls.

Other Hazardous Building Materials

• No quantifiable other hazardous building material identified within the project areas. Any concealed building materials discovered during renovation/demolition activities, which are suspected to contain hazardous materials should be investigated or tested to confirm the absence or presence of hazardous materials.

QuinnEvans-TMFJB-HazMatInsp_rpt;(QUINN-023);dta/ttn 13

5.0 LIMITATIONS

Every reasonable attempt was made to locate ACM, LBP, and other hazardous building materials within the project areas. However, areas that are inaccessible can only be addressed through extrapolation of conditions in accessible building space and review of building plans, specifications, or other building documents provided to Apex.

Although every attempt was made to identify suspect ACM, LBP, and other hazardous building materials in the inspected areas, it should be noted that it is possible for additional not identified or tested

ACM, LBP, PCB ballasts, and other hazardous building materials could be found within concealed areas of the locations included in this report. Future construction activities could expose additional suspect building components. If suspect, ACM, LBP, and other hazardous building materials are identified, Apex recommends additional assessment and analysis be performed.

Changes in the condition of the site may occur with time due to either natural processes or human activities. The findings presented in this report are based on site conditions existing at the time of the inspection. Apex cannot be responsible for any errors or omissions in this assessment resulting from incomplete or inaccurate disclosures.

1.0 ASBESTOS INSPECTION

Apex conducted the asbestos inspection of the building using guidelines set forth by the

Occupational Safety and Health Administration (OSHA) and the U.S. Environmental Protection Agency

(EPA).

Materials that were considered suspect were identified and the number of samples to be collected of these suspect materials was determined by the inspector using the Asbestos Hazard Emergency

Response Act (Title 40 CFR Part 763) (AHERA) protocols. As defined by AHERA policy, suspect materials include the following building material types:

1. Surfacing Materials – including spray-applied or troweled-on wall/ceiling coatings;

2. Thermal System Insulation (TSI) – including pipe insulation, and mudded pipe elbows, and;

3. Miscellaneous Materials –including ceiling tile, floor tiles and mastics, gaskets (if accessible), fire doors, wallboard and spackling.

Suspect materials that are homogeneous in nature (i.e., uniform in color and texture) were identified, touched to determine friability, and sampled by removing a small piece that was then placed in a labeled container. For a given homogeneous area, one (1) or more samples were collected in a randomly distributed manner in accordance with AHERA provisions as referenced in the OSHA Asbestos in

Construction standard (Title 29 CFR 1926.1101). Materials not considered by the AHERA standard as suspect ACM were not addressed by Apex during this inspection, unless specifically referenced.

Table 1 contains a list of the confirmed ACM. The information provided in this table includes detailed ACM descriptions, friability (ability to be reduced to powder by hand pressure), locations, and approximate quantities. Table 2 contains a list of homogeneous materials sampled; which provides a complete list of all identified suspect ACM. Each suspect material is grouped according to class (i.e., surfacing, TSI, or miscellaneous material). This table provides descriptions of each suspect ACM, general location, friability, samples collected, and ACM determination.

All bulk samples were sent to EMSL Analytical, Inc., of Cinnaminson, NJ, a National Voluntary

Laboratory Accreditation Program (NVLAP) accredited laboratory and analyzed using polarized light microscopy in conjunction with dispersion staining (PLM/DS) to determine asbestos content. Appendix B contains the laboratory results/chain-of-custody for all bulk samples collected by Apex during the asbestos

1.1 Sampling Protocol

Suspect building materials to be sampled were classified as friable or non-friable (as defined by the EPA). The materials were sampled to determine whether they are asbestos-containing [i.e., contain greater than one (1) percent asbestos]. Samples were analyzed for asbestos content using PLM/DS by a NVLAP accredited laboratory.

Suspect materials were sampled in general accordance with EPA's AHERA, as referenced in the most recent (September 1996) revision of the OSHA's Asbestos in Construction regulations

[Title 29 of the Code of Federal Regulations (29 CFR) 1926.1101], as follows:

MODIFIED AHERA SAMPLING PROTOCOL

Type of Material Estimated Quantity Required Samples

Sprayed or Troweled-on Surfacing Material

Greater than 5,000 ft2 7

Between 1,000 ft2 and 5,000 ft2 5

Less than 1,000 ft2 3

Thermal System Insulation All Quantities 3

Miscellaneous Materials All Quantities

Per AHERA, these materials must be sampled "in a manner sufficient to determine whether or not they contain asbestos." Apex generally collects 1 to 3 samples of such material based upon the inspector's judgment.

Note: These sampling protocol quantities are per functional area and/or homogeneous area.

A number of suspect ACM identified at the building warranted special scrutiny or otherwise required special consideration. These materials are:

• Floor tiles, resilient flooring, and mastics: All floor tiles, resilient flooring, and underlying mastics were considered suspect ACM. Each flooring material and its associated mastic were sampled and analyzed separately. If either component was found to contain greater than one (1) percent asbestos, then only that material was considered ACM. If carpeting was affixed to the floor, Apex’s procedure consisted only of pulling corners up to one (1) foot to view the material beneath. Based on this observation, the characterization of the homogeneous material underneath (i.e., tile or mastic), if any, was extrapolated to the entire floor surface of that area. Note: When only the mastic tests positive as ACM, the

2.0 LEAD BASED PAINT INSPECTION

Apex performed an x-ray fluorescence (XRF) lead-based paint (LBP) inspection of the project areas. The purpose of the inspection was to determine if LBP is present on the building components located within the interior project areas, which may be directly affected during the course of renovation activities.

The XRF LBP inspection was performed utilizing XRF spectrum analyzer to determine the presence of suspect lead-painted components. XRF technology is well known for accuracy in detecting lead within individual layers of paint. By emitting radiation through each paint layer, Apex was able to determine the presence of lead within tested components. Building components typically known for posing potential lead exposure were tested during the inspection. All XRF test results are found in Table 3.

Certain rooms/areas of the building, similar in design and construction history, were included within the representative LBP inspection. The current definition of LBP established by the District of Columbia is greater than 1.0 milligrams of lead per square centimeter of surface area (>1.0 mg/cm2) using a portable

XRF analyzer.

Apex’s on-site XRF lead-based paint inspection revealed none to be above the District of

Columbia’s definition for LBP.

The lead paint testing is intended to provide testing data to employers, as required by OSHA, so that measures may be taken to prevent lead exposures to workers during renovation and/or demolition activities. This inspection does not include risk assessment of lead hazard. It is important to note that even low concentrations of lead in paint (i.e., less than 1.0 mg/cm2) that do not meet the District of Columbia’s definition for LBP, have the potential to result in some lead exposure to building occupants and/or workers, particularly construction workers involved with activities such as torch cutting and welding metal structures, abrasive blasting, or sanding painted surfaces. Work practices involving the disturbance of such lead-containing paints or other materials are regulated under the U.S. Occupational Safety and Health

Administration’s (OSHA’s) Lead in Construction Standard in Title 29 of the CFR Part 1926.62. As a result, all construction and demolition activities involving lead-containing materials (regardless of the lead content)

• A ten (10)-day working day notification to the Department of Energy & Environment (DOEE) and a thirty (30) day occupant notice is required (If occupied) on NESHAP sized (greater than or equal to 160 square feet, 260 linear feet, or 35 cubic feet) asbestos abatement projects. Additionally, three

(3) days prior to the beginning of any abatement activities, post warning signs on the entrances/exits of the building.

Lead-based Paint

• No lead abatement is required prior to demolition. It is important to note that even low concentrations of lead in paint (i.e. less than 1.0 mg/cm2) that fall below the criteria for LBP, have the potential to result in some lead exposure to workers, particularly construction workers involved with activities such as torch cutting and welding metal structures, abrasive blasting, or sanding painted surfaces. Work practices involving the disturbance of such lead-containing paints or other materials are regulated under the OSHA’s Lead in Construction Standard in Title 29 of the CFR Part 1926.62.
