SAMPLING METHODOLOGIES

Suspect Asbestos-Containing Materials

(ACM)

The AHERA regulation, 40 Code of Federal Regulations (CFR) 763, is the primary governing regulation when performing asbestos surveys. This regulation was originally enacted for school buildings, but has since been applied to public and commercial buildings by the Asbestos School Hazard Abatement Reauthorization Act (ASHARA) in 1994 and by the Occupational Safety and Health Administration’s (OSHA) worker protection regulations in 1995, specifically 29 CFR 1926.1101(k). The demolition of structures is also subject to 40 CFR Part 61 “National Emission Standards for Hazardous Air Pollutants” (NESHAPs).

ACM is specifically addressed in 40 CFR 61 Subpart M “National Emission Standard for Asbestos.”

ACM is generally divided into three primary classifications as follows: (a) Surfacing Material, (b) Thermal System Insulation, and (c) Miscellaneous Material. These classifications are defined in 40 CFR

763.83 as provided below.

Miscellaneous material means interior building on structural components, structural members or fixtures, such as floor and ceiling tiles, and does not include surfacing material or thermal system insulation.

Surfacing material means material in a school building that is sprayed-on, troweled-on, or otherwise applied to surfaces, such as acoustical plaster on ceilings and fireproofing materials on structural members, or other materials on surfaces for acoustical, fireproofing, or other purposes.

Thermal system insulation means material in a school building applied to pipes, fittings, boilers, breeching, tanks, ducts, or other interior structural components to prevent heat loss or gain, or water condensation, or for other purposes.

The sampling methodologies generally employed to address the ACM categories described above are as follows.

Surfacing material – An accredited inspector shall collect, in a statistically random manner that is representative of the homogeneous area, bulk samples from each homogeneous area of friable surfacing material that is not assumed to be ACM, and shall collect the samples as follows:

FIRE PROTECTION REPAIRS, BLDG. NH95 GER 130-7939 Page 3

GER

(1) At least three bulk samples shall be collected from each homogeneous area that is 1,000 SF or less.

(2) At least five bulk samples shall be collected from each homogeneous area that is greater than or equal to 1,000 SF but less than or equal to 5,000

SF.

(3) At least seven bulk samples shall be collected from each homogeneous area that is greater than 5,000 SF.

Thermal system insulation - An accredited inspector shall collect the samples as follows:

(1) At least three bulk samples, in a random distributed manner from each homogeneous area of thermal system insulation that is not assumed to be ACM.

(2) Collect at least one bulk sample from each homogeneous area of patched thermal system insulation that is not assumed to be ACM if the patched section is less than 6 linear or square feet.

(3) In a manner sufficient to determine whether the material is ACM or not ACM, collect bulk samples from each insulated mechanical system that is not assumed to be ACM where cement or plaster is used on fittings such as tees, elbows, or valves.

(4) Bulk samples are not required to be collected from any homogeneous area where the accredited inspector has determined that the thermal system insulation is fiberglass, foam glass, rubber, or other non-ACBM.

Miscellaneous material - An accredited inspector shall collect the samples as follows:

(1) In a manner sufficient to determine whether material is ACM or not ACM from each homogeneous area of friable miscellaneous material that is not assumed to be ACM.

Non friable suspected ACBM - An accredited inspector shall collect the samples as follows:

If any homogeneous area of non friable suspected ACBM is not assumed to be ACM, then an accredited inspector shall collect, in a manner sufficient to determine whether the material is ACM or not ACM, bulk samples from the homogeneous are of non friable suspected ACBM that is not assumed to be ACM.

Lead, Cadmium and Chromium Paint Testing of painted surfaces for lead, cadmium and chromium was conducted by collecting bulk paint chip samples from various painted surfaces. The inspection was generally conducted using methodology recommended by the U.S.

Department of Housing and Urban Development (HUD). Modifications were made where appropriate for this project. It is important to note that this inspection was not a comprehensive, surface-by-surface evaluation, but rather a screening inspection of major painted components, which may contain lead, cadmium and chromium.

ANALYTICAL METHODS

Suspect Asbestos-Containing Materials

(ACM)

Suspect ACM samples were analyzed using polarized light microscopy (PLM) and dispersion staining techniques. The analytical method was conducted in accordance with Method EPA-600/M4-82-020 and/or EPA 600/R-93/116. In some cases additional analysis was performed using Transmission Electron Microscopy (TEM) with gravimetric reduction. Analysis was performed by EMSL Analytical, Inc., Cinnaminson, NJ NVLAP Lab Code 101048-0, AIHA-LAP, LLC-IHLAP Lab 100194, NYS ELAP 10872, NJ DEP 03036.

Paint Analysis Paint chip samples were analyzed for lead, cadmium and chromium using inductively coupled plasma (ICP) emission spectroscopy (SW-846, 6010C). Analysis was performed by EMSL Analytical, Inc. Cinnaminson, NJ NELAP Certifications: 10896, PA 68-00367, AIHA-LAP, LLC

ELLAP 100194, A2LA 2845.01

SITE DESCRIPTION

Building NH-95 was constructed in the 1950s.

There have been various additions to the building over the years. The building has concrete and structural steel framing with exterior masonry walls, flat built-up roof, and a pile supported crawl space foundation. Interior walls in common areas and hallways are CMU block and gypsum wallboard in Ops spaces. Flooring is mostly vinyl floor tile in common areas and hallways. Ops spaces have carpeted floors and raised floors over vinyl floor tile. Acoustic drop ceilings are found throughout the building.

FIRE PROTECTION REPAIRS, BLDG. NH95 GER 130-7939 Page 4

PREVIOUS HAZARDOUS MATERIAL REPORTS

The Government did provide a previous asbestos report. The Survey Report dated 10 July 1990 was performed by Harmon Engineering Associates, Inc.

The asbestos results summary page identified the following ACM in building NH95:

1. Vinyl floor tile and mastic

2. Ceiling tile 1’x1’

3. Steam pipe insulation

4. Pipe fittings

5. Pipe lagging

6. Duct insulation.

No lead paint sampling was included in the survey report.

A copy of the previous asbestos survey report is provided in Section 5 of this report.

According to NAVFAC renovations were performed in 2010 in areas 3 and 4 on the first and second floors of the building. Renovations were also performed in area 6 on the first floor. During the renovations, all ACM was removed in these areas.

ASBESTOS BULK SAMPLING AND ANALYSIS

In September, October, and November of 2021, a total of two hundred (200) bulk samples of suspect ACM were collected from NH95 to support the planned renovation project. In January and February of 2022, an additional fourteen (14) bulk samples of suspect ACM were collected. Two (2) additional samples were collected in May of 2022.

Samples were collected by Brian T. Hyde, a Virginia Licensed Asbestos Inspector.

The attached Table 1 is a summary of the sample materials, sample location, and laboratory results.

Laboratory results are contained in Section 2 of this report. Drawings showing the approximate sample locations, are contained in Section 3.

Destructive activities such as breaking into walls, ceilings, or floors were not performed in order to obtain samples. Therefore, if during the demolition process suspect hazardous materials are uncovered, they must be properly addressed.

As the sample results indicate, the following materials were determined to contain asbestos:

1’x1’ Acoustical wall tile 12” tan floor tile/mastic under raised floor Residual floor tile mastic under raised floor 12” white floor tile/mastic Joint compound Tan floor tile/mastic under rubber flooring 12” tan floor tile/mastic (bottom layer) 12” green floor tile/mastic (bottom layer) 12” tan/brown speckled floor tile/mastic Residual acoustical wall tile mastic

(trace) 9” brown floor tile/mastic under raised floor Residual floor tile mastic under raised floor Acoustical wall tile mastic Tan floor tile/mastic (bottom layer) Residual floor tile mastic under carpet Tan floor tile/mastic under carpet 9” grey floor tile/mastic under raised floor 9” green floor tile/mastic under 12” grey floor tile

Assumed ACM Fire Doors - The doors in the building were not destructively sampled for ACM for safety

FIRE PROTECTION REPAIRS, BLDG. NH95 GER 130-7939 Page 6 reasons. Therefore, all doors to be removed are classified as ACM. All doors should be inspected prior to disposal.

The following asbestos-containing materials are anticipated to be disturbed or removed during the fire protection repairs:

1. ACM floor tile under Non ACM flooring to include carpet, rubber flooring and tile in found in common areas and corridors. (Estimated quantity to be disturbed - 16,050 SF)

3. Cove base/mastic containing asbestos joint compound found on gypsum walls in corridors.

(Estimated quantity to be disturbed - 2,500 LF)

3. ACM floor tile & residual mastic under raised under raised flooring in OPS spaces. This material is not anticipated to be disturbed during the fire protection work.

4. ACM fire doors (assumed) found in corridors and common areas. (Estimated quantity to be disturbed - 21 Each) All Asbestos-Containing Materials must be removed prior disturbance due to renovation. Therefore the acoustical wall tile and mastic, floor tile and mastic, and fire doors must be removed by a Virginia licensed asbestos abatement contractor prior to disturbance due to renovation.

All asbestos abatement work, if required, shall be performed in accordance with local, Djibouti and US Federal regulations including but not limited to:

29CFR1926.1101 - Asbestos 40CFR61 - National Emission Standards for Hazardous Air Pollutants 9VAC 20-81 - Virginia Solid Waste Management Regulations 18VAC 15-20 - Virginia Asbestos Licensing Regulations

PAINT SAMPLING AND ANALYSIS

In October of 2021, a total of nine (9) paint chip samples were collected to support the planned renovation project. The paint samples were collected from representative paints observed in the project area and expected to be disturbed during the project. The attached Table 3 summarizes the samples collected and the laboratory analytical results. The laboratory analytical results are contained in Section 2. The purpose of our sampling was to obtain representative data on the concentrations of lead, cadmium and chromium in the existing painted surfaces scheduled to be disturbed by the work.

Our inspection services were not intended to meet the requirements of HUD sampling protocols for lead containing paint. Paint samples were analyzed using inductively coupled plasma emission spectroscopy (ICP). The analytical method was conducted in accordance with the NIOSH 7082 Method by Analytics Corporation, a National Lead Laboratory Accreditation Program (NLLAP) approved participant.

PAINT DISCUSSION

There are two frequently used standards to define lead-based paint, the Consumer Product and Safety Commission (CPSC) and the Department of Housing and Urban Development (HUD). In 1978, the CPSC, acting under the authority of the Consumer Product Safety Act, banned the sale of paint containing more than 0.06% lead by weight to consumers. The Consumer Product Safety Improvement Act of 2008 lowered the concentration of lead in paint that is permissible from 0.06% (600 ppm) to the new limit of 0.009% (90ppm), for specific paints and products. Paint which contains more than 0.009% lead by weight is defined as lead containing paint (LCP).

The Department of Housing and Urban Development (HUD) defines Lead-based paint (LBP) as any paint, varnish, shellac, or other coating that contains lead equal to or greater than

1.0 mg/cm2 as measured by X-ray fluorescence (XRF) analyzer or laboratory analysis, or 0.5% by weight as measured by laboratory analysis.

The Occupational Safety and Health Administration (OSHA) Lead in Construction Standard (29 CFR 1926.62) does not define lead-based paint.

However, to comply with OSHA, all painted surfaces with a lead concentration at or above the laboratory’s reporting limit (RL) should be considered lead containing.

Compliance with this standard is required even for paints with less than 0.5% or 0.009% lead by weight. Therefore, painted surfaces exceeding the MDL should not be disturbed without taking the appropriate precautions when performing certain

FIRE PROTECTION REPAIRS, BLDG. NH95 GER 130-7939 Page 7 high risk tasks. Activities such as scraping, sanding, welding/torching and disturbance of painted surfaces could potentially release leaded dust. OSHA has categorized the following high risks tasks into three groups:

Group 1: manual demolition manual scraping heat-gun applications power tool cleaning with dust collection system spray paint with lead-based paints

Group 2: lead burning using lead-containing mortar power tool cleaning without dust collection system rivet blasting cleanup activities where dry expendable abrasives are used movement and removal of abrasive blasting enclosures

Group 3: abrasive blasting welding, cutting and burning on steel structures

Analytical results for lead paint indicate that eight out of nine samples collected and analyzed resulted in a lead concentration above the RL. One paint sample was determined to be Lead Based Paint (LBP).

Therefore, all existing painted surfaces in the project area scheduled for renovation/demolition should be considered lead containing for the purposes of complying with 29 CFR 1926.62 in order to protect workers and the environment.

Paints containing cadmium and chromium are often found as protective coatings on structural steel or exterior coatings on metal surfaces. These paints tend to be red, yellow or orange and are typically the first layer. All of the bulk paint chip samples collected were also tested for cadmium and chromium.

Analytical results for cadmium indicate that one out of nine samples collected and analyzed resulted in a concentration above the RL.

Analytical results for chromium indicate that eight out of nine samples collected and analyzed resulted in a concentration above the RL.

The National Institute for Occupational Safety and Health (NIOSH) identifies chromium as a confirmed carcinogen and cadmium as a suspect carcinogen.

Construction Standards established by OSHA for lead, cadmium and chromium are:

Lead 29 CFR 1926.62 Cadmium 29 CFR 1926.1127 Chromium 29 CRF 1926.1126

The permissible exposure limits (PEL) established by OSHA are 5 ug/m3 for cadmium, 5 ug/m3 for chromium (chromates) and 50 ug/m3 for lead.

The PEL is an airborne measurement to address worker exposure. There is no direct correlation between lead, cadmium, and chromium concentrations in paint and worker exposure. Only when these concentrations are below the laboratory’s MDL, is worker exposure not an issue.

All painted surfaces should be assumed to be lead, cadmium and chromium containing for renovation purposes. Appropriate precautions should be taken during the disturbance of all painted surfaces to ensure protection of workers and the environment.

All lead, cadmium and chromium paint work shall be performed in accordance with all local, Djibouti and US Federal regulations to protect workers and the environment, including but not limited to:

29CFR 1926.62 - Lead 29CFR 1926.1126 - Chromium 29CFR 1926.1127 - Cadmium 9VAC 20-60 - Virginia Hazardous Waste Management Regulations 9VAC 20-81 - Virginia Solid Waste Management Regulations 18VAC 15-30 - Virginia Lead-Based Paint Activity Regulations

WASTE CLASSIFICATION FOR PAINTED

BUILDING COMPONENTS

Building components and demolition waste streams which are painted must be properly characterized prior to disposal. The EPA Resource Conservation and Recovery Act (RCRA) regulations establish the limits for RCRA leachable metals (lead, cadmium, chromium, etc.). Leachable metals means the

FIRE PROTECTION REPAIRS, BLDG. NH95 GER 130-7939 Page 8 amount of metals likely to leach from the waste into the surrounding soil/groundwater system of a landfill. The leachable concentration of chemicals in a waste stream is determined by an analytical method called the toxicity characteristic leaching procedure (TCLP). Waste stream TCLP concentrations that equal or exceed the RCRA limits must be transported to a hazardous waste treatment, storage, or disposal facility. Precautions should be implemented to prevent the storage of any hazardous waste for more the 90 days. Specific permits are necessary to store hazardous waste in excess of 90 days.

POLYCHLORINATED BIPHENYLS (PCBS) &

MERCURY LAMPS

On January 1, 1979, the Environmental Protection Agency (EPA) banned the manufacturing of light ballasts which contain PCB’s and phased out most PCB uses. Therefore, all light ballasts manufactured prior to January 1, 1979 without “Non-PCB” markings must be considered PCB containing. The EPA’s actions subjects all substances containing more than 50 ppm PCBs to regulatory control (with the exception of PCB-contaminated waste oil which is prohibited at any level).

Our field investigation of existing light fixtures indicated that the fixtures were newer T-8 fluorescent fixtures with electronic ballasts or LED light fixtures which do not contain ballast.

All ballast are assumed to be non PCB containing.

All fluorescent light tubes should be considered to be mercury containing and disposed of as universal waste.

Our estimate for handling incidential PCB containing ballasts and mercury tubes that may become damaged is 1,000 light tubes and 50 PCB ballasts.

PCBs must be managed and disposed of in accordance with the Toxic Substance Control Act of 1976 (TSCA) and any applicable state and local regulations. Contractors managing PCB waste should be properly trained and licensed or certified as required by Federal, state and local regulations.

All PCB and mercury work shall be performed in accordance with all local and US Federal regulations to protect workers and the environment, including but not limited to:

40CFR761 - Polychlorinated Biphenyls (PCBs) Manufacturing, Processing, Distribution In Commerce, and Use Prohibitions 40CFR273 - Standards for Universal Waste Management

EMSL maintains liability limited to cost of analysis . Interpretation and use of test results are the responsibility of the client. This report relates only to the samples reported above, and may not be reproduced, except in full, without written approval by EMSL. EMSL bears no responsibility for sample collection activities or analytical method limitations . The report reflects the samples as received.

Results are generated from the field sampling data (sampling volumes and areas, locations, etc.) provided by the client on the Chain of Custody. Samples are within quality control criteria and met method specifications unless otherwise noted. The above analyses were performed in general compliance with Appendix E to Subpart E of 40 CFR (previously EPA 600/M4-82-020 “Interim Method”) but augmented with procedures outlined in the 1993 (”final”) version of the method. This report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST or any agency of the federal government. Non- friable organically bound materials present a problem matrix and therefore EMSL recommends gravimetric reduction prior to analysis . Unless requested by the client, building materials manufactured with multiple layers (i.e. linoleum, wallboard, etc.) are reported as a single sample. Estimation of uncertainty is available on request.
