EXECUTIVE SUMMARY

AH Environmental Consultants (AH) has prepared this Hazardous Material Inspection

Report for the use of the Naval Facility Engineering Command (NAVFAC) Washington and Burns McDonnell Engineers to provide information concerning asbestos building materials, lead containing paints, or other recognized hazardous materials (HAZMAT) identified at Joint Base Andrews (JBA) Buildings 1539 and 1558, that may be impacted by work associated with the demolition of the buildings.

This site inspection and assessment was conducted by AH staff and involved sampling of suspect asbestos containing materials (ACM), testing of paint/coatings, investigation for mercury and polychlorinated biphenyls (PCBs), and other known potentially hazardous materials (HAZMAT) anticipated to be impacted by proposed work.

The primary HAZMAT concern for planned work activities appears to be asbestos containing pipe insulation and significant quantities of asbestos containing floor tiles.

Lead based paints pose a limited hazard. Items of special concern are present, but do not require significant safety controls. The precise means and methods to handle the identified hazardous materials are covered under project specifications, separate from this document.

Inspection at the facility was conducted 10-14 and 24 July, 2017 and included identification, sampling and analysis, evaluation of paint/ coatings and suspect ACM, inventory of other potentially hazardous materials that could impact planned work actions.

Asbestos inspection information is provided in Section 1. Lead inspection information is provided in Section 2. Section 3 contains information pertaining to mold and moisture concerns. Additional HAZMAT issues are contained in Section 4.

Site drawings indicating sample locations and information concerning the location of

HAZMAT are provided in Appendix A, a reference photo-log is included in Appendix B, JOINT BASE ANDREWS, MD EXECUTIVE SUMMARY

JOINT BASE ANDREWS, MD ASBESTOS

AH Environmental Consultants 1-1 September 2017

1. ASBESTOS

There is a well-known link between the inhalation of asbestos fibers and various diseases such as asbestosis, mesothelioma, lung and other cancers. As a result, the

Asbestos Hazard Emergency Response Act (AHERA, 40 CFR Part 763) was enacted.

An AHERA inspection requires an accredited inspector to visually inspect and assess the condition of all known or assumed friable asbestos-containing building materials

(ACM); to visually inspect non-friable ACM and touch it to determine friability; and to identify homogeneous areas of friable materials. The National Emission Standards for

Hazardous Air Pollutants (NESHAPs) require thorough inspections for asbestos in structures before renovation or demolition.

The intent of the inspection was to provide sufficient information to involved parties that may impact the renovations of project buildings and to prepare adequate abatement specifications for such. Bulk sampling of suspect ACM was performed. Samples were analyzed utilizing Polarized Light Microscopy (PLM) with dispersion staining (EPA method 600/M4/82/020). For confirmation, two floor tile samples were analyzed by

Transmission Electron Microscopy (TEM), NIOSH method 7402. The accredited laboratory reports of analysis are provided in Appendix C.

The sample identification system of this report consists of a three-unit sample identification number. The first set of digits indicates the building designation, the next set indicates the homogenous material grouping for the building, and the last two numbers indicate the consecutive sample number as collected in the field. For example, 44-01-03 would indicate that the sample was collected from Building 44, homogenous area one, and was the third sample collected [of that homogenous material] during the inspection. These sample numbers match the chain-of-custody, lab reports of analysis, and sample identification numbers on the drawings (Appendix A). No historical sample data was provided or referenced for this project.

AH Environmental Consultants 1-2 September 2017

Sample result summaries are provided in table format. Note that NAD in the % asbestos column indicates that there was No Asbestos Detected in the sample. Some sample results in this column may be displayed in this report with a slash between two numbers, (#/#). The first number represents the first material listed under the material location/description and the second number represents the second material listed.

Sampled materials that contain asbestos are highlighted in bold red.

The samples are also grouped into homogeneous material/area groups. Homogeneous materials are suspect materials that are uniform by color, texture, construction/application date and general appearance. Photos of ACM are included in the reference photo-log (Appendix B) for assistance in later material identification.

Sample summary tables also distinguish whether materials are considered friable (able to be crushed or pulverized by hand pressure) or non-friable (not able to be crushed or pulverized by hand pressure) for the purpose of determining the ACM category. The collected samples were at least l cubic centimeter and were placed in a sealed container at the time of collection. Appropriate precautions were taken to prevent exposure to those present in or around the facility during the collection of samples, including wet collection methods.

As previously mentioned, the asbestos NESHAP (40 CFR 61, subpart M) requires a thorough inspection for asbestos in structures before the renovation or demolition of those structures. Materials determined to be ACM (containing greater than 1% asbestos) must also be categorized for removal and demolition purposes. The various categories for ACM are shown in the following chart.

AH Environmental Consultants 1-3 September 2017

ACM Category (NESHAP)

Categories Typical Material

Type Guidance for RACM

Friable ACM Pipe insulation fittings

Able to crush with hand pressure

Cat I, Non-friable Floor coverings, Roofing products, Gaskets

Non-friable materials that have become friable, or Non-friable material that is or will be damaged due to sanding, grinding, cutting, or abrading

Cat II, Non-friable

Cement siding (Transite), Significantly damaged tile

Non-friable material that has a high probability of becoming or has become friable by forces expected to act on the material in the course of renovation or demolition

Any ACM that is Friable, or Category I and II Non-friable that meets the qualifications to be considered a Regulated Asbestos-Containing Material (RACM), must be removed prior to demolition or disturbance that would break up, dislodge, or similarly destroy the material or preclude access to the material for subsequent removal. This includes gasket materials.

The findings of the asbestos inspection are detailed in the following section, including recommendations for action.

1.1 ASBESTOS INSPECTIONS

The initial work plans called for the demolition of Buildings 1539 and 1558. A visual survey was performed of accessible suspect ACM at all aforementioned sites and included the interior and exterior of the structures, including the area roofing now under framed metal roofing. Details are listed following.

1.1.1 Building 1539

The building is a block and concrete construction that houses communications operations and equipment. Most of the structure components and materials appeared substantially original to the construction with localized renovations of the interior and an addition on the East side.

AH Environmental Consultants 1-4 September 2017

The asbestos survey identified twenty-five (25) unique homogenous suspect materials.

The homogenous materials identified include:

Various 9” and 12” floor tiles and adhesives/mastics

Miscellaneous caulking and sealants

Carpet adhesive

Ceiling tile

Drywall and joint material

Asphaltic roofing and tar

Pipe wrap, black

Floor leveling compound

Vinyl base material

Bulk sampling was performed on the suspect ACM found in the survey area. Forty-one

(41) samples were collected for asbestos analysis which included sixty-four (64) individual layers for analysis. A summary of sample results are provided in Table 1-1.

Asbestos containing materials were identified.

1.1.1.1 ACM Notes 1539

There is an estimated 8400 square feet of ACM floor tile present. If reuse of concrete slab is anticipated, removal would be required. Depending on method of demolition, AH Environmental Consultants 1-6 September 2017

Category I non-friable ACM may stay in place if all debris is hauled to a landfill approved to accept non-friable ACM debris. Additionally, ACM mastic remains on approximately

1725 square feet of concrete slab where tile has been removed.

Exterior caulking material at older doors and at brick expansion joints contains asbestos.

There is an estimated 245 linear feet of this non-friable ACM.

One location of ACM electrical sealant/ putty was identified. Other hidden locations are possible. This material is unlikely to become friable.

1.1.2 Building 1558

The building is a block and concrete construction that houses communications operations and equipment. Most of the structure components and materials appeared substantially original to the construction with localized renovations of the interior creating isolated secure areas (aka: SCIFs).

The asbestos survey identified twenty-seven (27) unique homogenous suspect materials. The homogenous materials identified include:

Duct insulation

Pipe insulation and mudded fittings

Roofing materials

Drywall and joint material

Floor leveling compounds

Various 12” and 9” floor tile and adhesive combinations

Ceiling tiles

Miscellaneous sealants and packings

Miscellaneous adhesives

Sink undercoating’s

Vinyl threshold material

Acoustical tiles

Cementitious plaster

Bulk sampling was performed on the suspect ACM found in the survey area. Seventy-five (75) samples were collected for asbestos analysis which included one hundred

AH Environmental Consultants 1-7 September 2017 twenty-three (123) individual layers for analysis. A summary of sample results are provided in Table 1-2. Asbestos containing materials were identified.

1.1.2.1 ACM Notes 1558:

Approximately 220 linear feet of large (>12” diameter) ACM TSI insulation was identified as generator exhaust flues. This friable ACM is dangerous and shall be removed prior to demolition. Additionally, 60 linear feet of smaller (<12” diameter) ACM TSI insulated lines was determined present. Most is accessible, including ACM TSI fittings on fiberglass insulated lines. Of concern are ACM lines within walls which were hidden from view during the inspection. During demolition, caution should be used in the event additional hidden material is uncovered.

There is an estimated 13,500 square feet of ACM floor tile remaining in the building, most under carpet. If reuse of concrete slab is anticipated, removal would be required.

Depending on method of demolition, Category I non-friable ACM may stay in place if all debris is hauled to a landfill approved to accept non-friable ACM debris.

An un-renovated section in the central main conference room contains ACM acoustical tile and adhesive. This material is presently non-friable but can become friable and should be removed as such. There is an estimated 100 square feet in the area.

Older overhead duct systems wrapped with silver foil backed fiberglass near the central portions of the building contains asbestos sealant on the duct seams. The material will

AH Environmental Consultants 1-10 September 2017 unlikely become friable and therefore may remain during demolition, provided disposal regulations are followed.

1.2 RECOMMENDATIONS

Friable ACM pipe insulation material must be removed prior to demolition as a Class I abatement of friable ACM.

Acoustical wall tiles are recommended for removal as a Class I abatement of friable

ACM.

Primarily non-friable asbestos containing materials were identified during the inspection.

Abatement is recommended of all Class II non-friable ACM.

During demolition or renovation, any building material that is not identified as homogenous with those addressed in this report must be considered as an ACM unless additional testing indicates otherwise. Locations of samples and known ACM are indicated on the inspection drawings (Appendix A).

The following work practice should be followed whenever activities involving any ACM occur at this facility:

Ensure any ACM is managed in accordance with Federal and Maryland regulations.

Remove any ACM that may be disturbed during renovations or ensure the material will not be disturbed and/or become friable.

Always keep any ACM adequately wet before, during, and after removal operations.

Conduct activities in a manner which produces no visible emissions to the outside air.

Handle and dispose of all ACM in accordance with Federal and Naval regulations.

Additional inspection information is included in the appendices on the lab reports of analysis chain of custody documents and building drawings

BUILDINGS 1539 AND 1558 SECTION 2

JOINT BASE ANDREWS, MD LEAD

AH Environmental Consultants 2-1 September 2017

2. LEAD

Since 1971, the construction industry has been required to protect workers from exposure to lead through engineering and work practice controls. The current OSHA regulations 29 CFR 1926.62 set the following limits for lead exposure including a permissible exposure limit (PEL) lead of 50 micrograms per cubic meter (µg/m3), and an action level of 30 µg/m3, as determined using an 8-hour time weighted average. Since lead-based paint has been determined to be a health threat, assessment of buildings for the presence of lead-based paint is required in order to prevent occupational exposure to personnel or the general public, and to enact appropriate control measures for lead hazards.

OSHA and EPA regulations must be followed when renovation or demolition work affects any lead based paint (LBP) or paints with detectable lead levels referred to as paint containing lead (PCL). X-ray fluorescence (XRF) was the primary method used to identify paints containing lead at Buildings 1539 and 1558. No bulk paint, soil, and waste stream sampling was conducted.

The preconstruction inspections primary purpose is to identify major building components containing lead in order to properly address the lead during renovation/ demolition that may be impacted by the proposed work for the purpose of OSHA compliance. The inspection was conducted using the EPA’s work practice standards for conducting lead-based paint activities (40 CFR 745.227) as a guide and all State and local regulations.

Disturbance of paint containing lead requires special training and initial exposure monitoring at a minimum. Above 0.5% by weight (bulk paint) or 0.7 mg/cm2 (XRF), paint is considered to be lead-based. However, in the interest of safety, lower thresholds are utilized in construction since OSHA standards 29 CFR 1926.62 (Lead in

Construction) are invoked if any lead is present in the paint; there is no minimum concentration level.

AH Environmental Consultants 2-2 September 2017

These standards set forth the regulations that apply with regards to construction or renovation of painted materials or structures that contain detectable amounts of lead and not necessarily lead pigment containing items that have been manufactured.

Lead sample data sheets are included in Appendix C.

2.1 SAMPLING

XRF sampling does not require collection of material and is considered non-destructive.

This state-of-the-art method for determining the composition of painted surfaces can quickly determine if a surface contains LBP/PCL or not, and provides sufficient data concerning the amount of lead contained in paint. Data is provided as recorded by the

XRF unit at the time of survey using pre and post calibration, and by following the performance characteristic sheet of the equipment. Areas are immediately identified as coated with LBP/PCL using this method.

Most components tested are believed to contain several layers of paint film and are difficult to interpret. XRF and bulk paint analysis does not differentiate which layer of paint may contain lead. The results only indicate the amount of lead that is present in the sample/test location. Lead is likely to be present at a higher percentage in a particular layer than reported due to averaging the weight of other layers of paint into the calculation. For this reason, OSHA standards apply to any sample with detectable lead.

Construction activities that impact these paints may result in exposure to lead, even though they are not technically considered lead-based paints.

Results of the lead testing conducted are presented in the following sections.

2.2 XRF RANGES

An inspection was performed on painted and limited non-painted components to be suspect for the presence of lead found at the project buildings. Readings were then taken of a representative number of surfaces, dependent on the quantity of the particular material present. Although OSHA utilizes the term “any detectable lead”, the amount of

“detectable lead” is relevant in order to determine the potential for lead exposure.

Information is presented in a lead range format to assist in determining protective measures and special procedures that may be required during renovation/ demolition activities. The readings were categorized as follows:

Lead-Based Paint [ L. ] or >0.70 mg/cm2 lead;

Containing Elevated Lead [ E ] or between 0.70 - 0.50 mg/cm2 lead;

Containing Lead of Concern [ C ] or between 0.49 -0.25 mg/cm2 lead;

Detectable Levels of Lead [ D ] or between 0.24 - 0.05 mg/cm2 lead.

Readings below 0.05 mg/cm2 lead were considered insignificant.

2.3 LEAD COMPONENTS

Lead inspection of Buildings 1539 and 1558 was conducted on 12-14 July 2017. Three hundred seventy-eight (378) total readings were taken, which includes twenty-four (24) test standards for calibration.

2.4 LEAD BATTERIES

Reserve power systems in both buildings are by generator, but a battery bank is used as well. A significant quantity of deep cycle, wet cell lead acid batteries are present. These should be taken intact for recycling.

Lead batteries are also present at emergency lighting fixtures, older exit lights, and as starting power for electrical generators in 1558.

2.5 COMMENTS/RECOMMENDATIONS

Occupational exposure to persons conducting disturbance or removal of paint can result in elevated blood lead levels. Lead paint becomes an increased hazard when it deteriorates and oxidizes and/or is present as lead dust. Ingestion and potentially inhalation of resulting dusts may cause lead related health problems.

Based upon the lead sampling results, worker exposure testing would be required during the demolition since components containing lead are not intact and likely to be disturbed.

Under no circumstances should interior torch cutting of metals coated with lead since it poses an immediate hazard as heavy metal vapors resulting from the intense heat and are acutely more toxic than airborne particulates. The use of non-torch methods are always preferred, although chop saw cutting also releases particulates into the air posing a risk to equipment operators and risk of area contamination.

A toxicity characteristic leachate procedure (TCLP) test was not conducted on bulk structural components of this project since the mass of debris has yet to be ascertained.

AH Environmental Consultants 2-6 September 2017

Note: when scrap metal is disposed of at a reclamation facility, the materials are exempt from regulation as a potentially hazardous waste [EPA 40 CFR 261.6 (a)(3)(ii)].

The following measures are recommended to conduct operations safely during site operations.

Follow OSHA and EPA regulations when performing construction operations affecting paints containing lead.

Inform facility personnel of the inspection findings.

JOINT BASE ANDREWS, MD OTHER HAZARDS

AH Environmental Consultants 3-1 September 2017

3. OTHER HAZARDS

In addition to asbestos and lead, various additional issues relevant to the project were included in the building assessment. The additional concerns assessed and protocols followed during the assessment are described in this section.

Older building renovation creates additional items of concern; specifically elemental mercury in the fluorescent light bulbs, potential , lead in backup power systems, . In addition, buildings may contain mercury switches in thermostats and other materials of special concern. A brief narrative concerning other potentially hazardous materials

(OPHMs) are discussed below.

3.1 MERCURY

Mercury is a toxic elemental metal with unique properties, including being in a liquid state at room temperatures. Human intake of mercury is primarily through oral means.

Inhalation of mercury vapor is another source of human exposure. Once absorbed, mercury in all forms is distributed via the blood steam to all tissues in the body. Chronic exposure to mercury primarily affects the central nervous system and kidneys.

Mercury is used in a wide variety of common products including:

Fluorescent and neon lamps, Mercury vapor and high pressure sodium lamps, Switches and relays, Thermostats and regulators, and

Thermometers and manometers,

3.1.1 Mercury Lamp Inspection

The use of fluorescent and high-intensity discharge (HID) lamps is a wise choice for lighting sources since they can use up to 50 percent less energy than incandescent lighting. However, fluorescent and HID lamps contain mercury and therefore must be

AH Environmental Consultants 3-2 September 2017 properly managed. Although low mercury lamps (e.g. T5, T8) contain approximately one-tenth the amount of mercury as standard lamps, they still must be handled properly.

Building 1539: contains approximately 3,464 linear feet of fluorescent lamp total, most in U shaped bulbs (2 each per 2x2 unit).

Fire strobe lights and all other HID lighting present should be collected for recycling as well.

Building 1558: contains approximately 5,640 linear feet of fluorescent lamp total, most also in U shaped bulbs.

3.2 MERCURY SWITCH INSPECTION

Buildings were inspected for older style thermostats that are likely to contain mercury tilt switches. No old style thermostats containing a mercury vial were identified during the building inspection. If any are identified during the course of renovation or demolition, they are likely to contain mercury switches. The mercury is in a liquid state, within a small glass vial.

3.3 PCBS

Another potential concern associated with building renovations is the presence of PCBs.

Inspections included a visual survey of light fixtures to determine if pre-1980 fixtures were present.

PCBs are synthetic organic chemicals that were produced in the United States from

1929 to 1977. A major use of PCBs was in fluorescent light fixture ballasts (in the capacitor). PCBs have been demonstrated to cause a variety of adverse health effects including cancer and a number of serious non-cancer health effects in animals.

Only electronic style ballasts were identified during inspection. Therefore, no PCB ballasts are believed to be present. All ballasts manufactured after 1 July 1978 that do not contain PCBs are required to be clearly marked “NO PCBs”. Ballasts without a date of manufacture or clearly marked “NO PCBs” must be assumed to contain PCBs.

AH Environmental Consultants 3-3 September 2017

3.4 RECOMMENDATIONS

Broken fluorescent and HID lamps must be managed as a hazardous waste. However, the Federal Government and most locales have adopted disposal regulations for handling fluorescent and HID lamps as a universal waste based upon a “recycling presumption”. Through recycling and proper handling of spent lamps as a universal waste, the burdens and liabilities placed upon disposers are reduced. Recycling facilities reduce lamps to their primary components: spent glass, aluminum, and phosphor and mercury powder.

Although most light ballasts identified during the inspection do not contain PCBs, it is

NAVFAC policy [specification 02 82 16.20] to dispose of all ballasts in an environmentally preferred manner. Therefore, all fluorescent light tubes (including those deemed low mercury), HID lights, and all ballasts should be packaged intact and sent to an approved recycling facility for disposal/recycling.

All batteries (lead acid, lithium, NiMH, or NiCd) should be recycled per the facility collection protocols/ program. This prevents hazardous materials from entering the environment.

Recycling to the extent feasible and cost effective is the preferred method of disposition of most materials, where applicable.
