PROJECT DESCRIPTION

Project information is per the Statement of Architect-Engineer Services (SAES) Revision 18 dated April 2021, provided by Clark Nexsen (CN).

This project is titled “FY 23 MILCON Project P-1514, Shoot House.” The project is described in the SAES, and Attachment 16 as follows:

SAES - D2. Development of the Design: The project(s) covered by this T.O. require(s) the preparation of a DBB construction contract package (i.e. drawings, specifications, basis of design (BOD), design analysis, engineering calculations, cost estimate, studies, and investigations, etc.).

Design submittals will be due at the Design Development (35-50%), 65% Over The Shoulder Review, Pre-Final (100%) and Final Corrected Design stages. The DBB Design must be developed in accordance with the Basic IDIQ Contract SAES, FC 1-300-09N, and as described in this SAES.

Attachment 16 - The objective of this Statement of Work (SOW) is to provide the organizational framework necessary to obtain an Environmental and Hazardous Materials (HAZMAT) Survey related to the planned demolition of building RR249 and associated utilities as part of the project to construct a new Shoot House at Stone Bay, Marine Corps Base Camp Lejeune, NC on an adjacent site.

Our scope of work was to perform an inspection of the building and collect bulk samples of suspect asbestos-containing materials (ACM) and paint chip samples to determine RCRA metal concentrations.

We also inspected existing lighting fixtures for PCB-containing ballasts collected wipe samples for lead and collected surface soil samples for lead analysis around the perimeter of the Building

RR249.

BUILDING DESCRIPTION

According to SAES Attachment 16 Building RR249, was constructed in 1998. The building contains approximately 4,800 square feet. The Building is a high bay 1-story structure which serves as a practice shooting facility.

The building consists of a pre-engineered metal building. The exterior of the building, including the walls and roof are covered with metal panels. The interior of the building includes a concrete floor and various timber frames partition walls. Many of the partition walls are covered with a product named “Armorcore.”

There is a catwalk located below the roof in the building. This catwalk is used by instructors during training activities.

The building is ventilated using three ventilation fans and associated metal ductwork. The ventilation fans are mounted on the metal roof.

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

P-1514 Shoot House Building RR249 GER 130-8061 Page 2

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 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 are, bulk samples from each homogeneous area of friable surfacing material that is not assumed to be ACM, and shall collect the samples as follows:

(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 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 are 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 BASED PAINT (LBP)

Testing of painted surfaces for lead, cadmium and chromium was conducted by collecting bulk paint chip samples from various painted surfaces. It is important to note that this inspection was not intended to meet the requirements of HUD sampling protocols for lead paint and was not a comprehensive, surface-by-surface evaluation, but rather a screening inspection of major painted components, which may contain LBP.

WIPE SAMPLING

Wipe sampling was performed using a gauze provided by Eurofins Laboratory. A 100cm2 template was placed on the surface area to be sampled. The gauze was removed from the paper package and wetted with distilled water. The area inside the template was wiped with firm pressure using “S” stokes covering the entire surface (edge to edge). The exposed side of the gauze was folded inward. The area was again wiped with the gauze

P-1514 Shoot House Building RR249 GER 130-8061 Page 3

GER

using S-strokes, starting at right angles to the first wipe. The exposed side of the gauze was again folded inward. The area was again wiped with the twice folded gauze using S-strokes in the original direction. The sample gauze was placed inside the laboratory provided plastic container, sealed and labeled and preserved on ice and forwarded to the laboratory using chain of custody controls.

SOIL SAMPLING

Soil samples were collected using a stainless steel trowel. The soil samples were collected from the upper 6-inches of soil. The soil was placed in clean, 4-ounce glass containers provided by Eurofins Laboratory. The containers were sealed, labeled preserved on ice and forwarded to the laboratory using chain of custody controls.

TCLP SAMPLING

Subsamples of various building materials were collected to form a composite sample for TCLP analysis. The composite sample consisted of a minimum of 105 grams of various building materials. The subsamples we placed into plastic bags, sealed, labeled preserved on ice and forwarded to the laboratory using chain of custody controls.

ANALYTICAL METHODS

PREVIOUS REPORTS

The Government did not provide a previous hazardous materials report for Building RR249.

FIELD INVESTIGATION

BUILDING INSPECTION

We performed an inspection of Building RR249 at MCB Camp Lejeune on August 30, 2022. The purpose of the inspection was to identify and sample, as required, suspect ACM, paint containing RCRA metals, and lighting containing PCB electrical ballasts and mercury lamps. Additional we performed an assessment of the building and soils around the building for residual lead.

ASBESTOS INSPECTION

A visual inspection of the building was performed and identified the following building materials:

1. Painted wood walls and ceilings,

2. Rubber sheets on the inside of the exterior walls,

3. Painted CMU walls, P-1514 Shoot House Building RR249 GER 130-8061 Page 4

4. Unpainted timber framing,

5. Unpainted concrete floor,

6. Painted structural steel,

7. Metal exterior panel walls and roof,

8. Metal exterior doors,

9. Hollow wood interior doors,

10. Three ventilation fans mounted on the roof of the building along with metal ductwork,

11. Fiberglass wallboard.

We did not readily observe miscellaneous sealants, plumbing, thermal system insulation, floor tile and mastic or acoustical ceilings in the building.

Four (4) bulk samples of suspect asbestos-containing materials (ACM) were collected. The suspect ACM samples included: tan duct mastic on metal ventilation ductwork, and CMU block filler. The attached Table 1, in Section 2 lists the sample materials, sample location, and laboratory results. Drawings showing the approximate sample locations are provided in Section 3.

As the sample results indicate no samples were determined to contain asbestos.

ASBESTOS DISCUSSION

The EPA defines ACM as any material which contains greater than 1% asbestos by weight.

Laboratory analysis of bulk samples collected during the field investigation did not identify ACM.

If asbestos abatement work is necessary due to unforeseen conditions, it must be performed in accordance with local, state and Federal regulations including but not limited to:

29CFR1926.1101 - Asbestos 40CFR61 - National Emission Standards for Hazardous Air Pollutants 10A NCAC 412C.0600 - North Carolina Asbestos Hazard Program 15A NCAC 13A - North Carolina Hazardous Waste Management 15A NCAC 13B - North Carolina Solid Waste Management

Marine Corps Base Camp Lejeune Environmental Affairs Division regulations.

PAINT SAMPLING

Two (2) paint chip samples were collected by GER.

The purpose of our sampling was to obtain representative data on the concentrations of the 8 RCRA metals (Arsenic, Barium, Cadmium, Chromium, Lead, Mercury, Selenium and Silver) in the existing painted surfaces scheduled to be disturbed by the work. Paint was collected from building materials which may be disturbed during the demolition.

Our inspection services were not intended to meet the requirements of HUD sampling protocols for lead paint.

The attached Table 2, in Section 2 lists the sample materials, sample location, and laboratory results.

Drawings showing the approximate sample locations are provided in Section 3.

LEAD, CADMIUM, & CHROMIUM 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 Department of Housing and Urban Development (HUD) defines lead-based paint 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.

Compliance with this standard is required even for paints with less than 0.5% or 0.06% lead by weight. Therefore, painted surfaces exceeding the MDL should not be disturbed without taking the appropriate precautions when performing certain high risk tasks. Activities such as scraping, sanding, welding/torching and disturbance of painted surfaces could potentially release leaded

P-1514 Shoot House Building RR249 GER 130-8061 Page 5 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

Sampling results for lead paint indicate that both samples collected and analyzed were found to have lead concentrations above the laboratory's reporting limit. The samples were not determined to be LBP. Therefore, all existing painted surfaces 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. The bulk paint chip sample was also tested for cadmium and chromium. Both samples collected and analyzed indicated concentrations above the reporting limit for cadmium and chromium. The National Institute for Occupational Safety and Health (NIOSH) identifies chromium and cadmium as a confirmed carcinogen. Construction Standards established by OSHA for cadmium and lead are:

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

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. If the PEL is exceeded, appropriate measures must be taken to reduce the hazard and provide training and personal protective equipment.

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.

Therefore, all existing painted surfaces scheduled for renovation/demolition should be considered lead, cadmium, and chromium containing for the purposes of complying with 29 CFR 1926.62 and 29 CFR 1926.1126, and in order to protect workers and the environment.

Additionally, the paint samples were analyzed for Arsenic, Barium, Mercury, Selenium and Silver.

Both paint samples contained concentrations above the laboratory reporting limit for Arsenic, Barium, Selenium and Silver. Mercury was not detected at a concentration above the laboratory reporting limit.

Appropriate precautions should be taken during the disturbance of all painted surfaces to ensure protection of workers and the environment.

All paint disturbance work shall be performed in accordance with all local, state and 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 15A NCAC 13A - North Carolina Hazardous Waste Management 15A NCAC 13B - North Carolina Solid Waste Management

Marine Corps Base Camp Lejeune Environmental Affairs Division 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

P-1514 Shoot House Building RR249 GER 130-8061 Page 6 limits for RCRA leachable metals (lead, cadmium, chromium, etc.). Leachable metals means the 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

LEAD WIPE SAMPLES

Lead dust wipe samples were collected from various surfaces inside Building RR249. Five lead dust wipe samples designated as W1 through W5 were collected. The samples were collected from both horizontal and vertical surfaces as follows:

W1: Concrete floor wipe sample, horizontal surface, lead concentration 80 ug/100 cm2 (743.2 ug/ft2).

W2: Concrete floor wipe sample, horizontal surface, lead concentration 660 ug/100 cm2 (6,131.4 ug/ft2).

W3: On top of a partition wall, horizontal surface, lead concentration 710 ug/100 cm2 (6,595.9 ug/ft2).

W4: Rubber coated exterior wall, vertical surface, lead concentration 2.9 ug/100 cm2 (23.94 ug/ft2).

W5: Rubber coated exterior wall, vertical surface, lead concentration 1.7 ug/100 cm2 (15.79 ug/ft2).

Lead dust wipe concentrations ranged from 1.7 ug/100 cm2 (15.79 ug/ft2) to 710 ug/100 cm2

(6,595.90 ug/ft2).

The attached Table 3, in Section 2 lists the sample materials, sample location, and laboratory results.

Drawings showing the approximate sample locations are provided in Section 3.

LEAD WIPE SAMPLES DISCUSSION

Typical bullets use lead styphnate and lead peroxide among other materials in the bullet primer. In some cases the bullet may also contain lead. We do not know anything about the weapons or ammunition used in the building. The source for the lead dust is likely to be the primer associated with the ammunition used in the weapons.

There are two regulatory protocols to use with regards to evaluating lead wipe sample concentrations.

One protocol is 40 C.F.R. Part 745 - Lead-Based Paint Poisoning Prevention in Certain Residential Structures. This protocol describes the lead dust clearance level for lead in dust as 10 ug/ft2 for floors, 200 ug/ft2 for interior window sills and 400 ug/ft2 for window troughs.

The second protocol is based on the OSHA Technical Manual. The surface contamination calculations described in the OSHA Technical Manual assumes the area of a workers hand is 100 cm2. This area is the same as the surface wipe sample area. Thus, the amount of contaminant in a 100cm2 sample could all be transferred to a worker’s hand upon contact. The OSHA Technical Manual describes a method to calculate an acceptable surface limit. The calculation requires the TLV for lead inhalation exposure which is 50 ug/m3 based on 29 CFR 1926.62. In this case the TLV is the same as the PEL for lead. The TLV is multiplied by the volume of air inhaled by an average worker in an eight-hour workday, which is 10m3. Multiplying 50 ug/m3 times 10m3 yields 500 ug as an acceptable lead dose. Dividing the acceptable lead dose by the approximate surface area of a worker’s hand results in an acceptable surface limit of 5 ug/cm2.

The lead concentration in each of the lead wipe samples exceeded the HUD clearance level of 10 ug/ft2.

The lead concentration in lead wipe samples W1, W2, and W3 exceeded the calculated OSHA acceptable surface limit of 5 ug/cm2.

Prior to the demolition of the building it should be properly deconned to collect the residual lead dust and to prevent it from spreading to the surrounding soil. The decon work should be monitored to ensure the workers are not exposed to airborne lead concentrations greater than the those specified in 29CFR 1926.62 - Lead.

P-1514 Shoot House Building RR249 GER 130-8061 Page 7

All lead dust cleanup work shall be performed in accordance with all local, state and Federal regulations to protect workers and the environment, including but not limited to:

29CFR 1926.62 - Lead 15A NCAC 13A - North Carolina Hazardous Waste Management 15A NCAC 13B - North Carolina Solid Waste Management

Marine Corps Base Camp Lejeune Environmental Affairs Division regulations.

LEAD SOIL SAMPLES

To assess the soil around the perimeter of the building for lead exterior soil sampling was conducted. The soil surrounding the building generally consisted of gravel and dirt. One soil sample was collected on each side of the building.

The attached Table 4, in Section 2 lists the sample materials, sample location, and laboratory results.

Drawings showing the approximate sample locations are provided in Section 3.

EPA defines a soil lead hazard as bare soil on residential real property or on the property of a child-occupied facility that contains total lead equal to or exceeding 400 parts per million (ppm) in a play area, or an average of 1,200 parts per million of bare soil in the rest of the yard based on soil samples.

LEAD SOIL SAMPLES DISCUSSION

Lead is a naturally occurring element found in soil.

The lead concentration can vary depending on location and historical use of the property.

Lead was detected in each of the four soil samples collected and analyzed around Building RR249. The lead concentrations ranged from 13 mg/Kg to 390 mg/Kg.

EPA defines a soil lead hazard as bare soil on residential real property or on the property of a child-occupied facility that contains total lead equal to or exceeding 400 parts per million (ppm) in a play area, or an average of 1,200 parts per million of bare soil in the rest of the yard based on soil samples.

The lead concentrations in the soil samples did not exceed 400 ppm. The lead in soil should not present an issue; however, if the soil is to be disturbed and removed from the site additional soil characterization will be required.

All lead soil disturbance work shall be performed in accordance with all local, state and Federal regulations to protect workers and the environment, including but not limited to:

29CFR 1926.62 - Lead 15A NCAC 13A - North Carolina Hazardous Waste Management 15A NCAC 13B - North Carolina Solid Waste Management

Marine Corps Base Camp Lejeune Environmental Affairs Division regulations.

TCLP SAMPLE

One composite TCLP sample was obtained from the various building materials in Building RR249.

Subsamples were collected from painted CMU, painted wood inside the building and a painted wooden door inside the building.

The sample was analyzed for TCLP RCRA 8 metals (Arsenic, Barium, Cadmium, Chromium, Lead, Mercury, Selenium and Silver). Laboratory analysis did not identify any RCRA metal concentrations above the laboratory reporting limit.

The attached Table 5, in Section 2 lists the sample materials, sample location, and laboratory results.

Based on the TCLP sample analysis the building materials do not appear to be hazardous.

POLYCHLORINATED BIPHENYLS (PCBS)

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 over 50 ppm PCBs to regulatory control (with the exception of PCB-contaminated waste oil which is prohibited at any level).

P-1514 Shoot House Building RR249 GER 130-8061 Page 8

Our field investigation of existing light fixtures indicated the fixtures inside the building were T-8 fluorescent lamps. There were a total of forty-four

(44) fluorescent light fixtures in the building. T-8 fixtures generally contain electronic ballasts which are not PCB containing.

The exterior lighting on the building appeared to be LEDs.

Any non-electronic ballast not marked “No PCB’s” must be considered to contain PCB’s.

All PCB work shall be performed in accordance with all local, state and 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 15A NCAC 13A - North Carolina Hazardous Waste Management 15A NCAC 13B - North Carolina Solid Waste Management

Marine Corps Base Camp Lejeune Environmental Affairs Division regulations.

MERCURY CONTAINING LAMPS

The fluorescent light fixtures in the building contained T8 fluorescent lamps. The lamps contain mercury and should be recycled. The building contains a total of 176 fluorescent lamps.

All mercury containing lamp recycling shall be performed in accordance with all local, state and Federal regulations to protect workers and the environment, including but not limited to:

15A NCAC 13A - North Carolina Hazardous Waste Management 15A NCAC 13B - North Carolina Solid Waste Management

Marine Corps Base Camp Lejeune Environmental Affairs Division regulations.

PCB SEALANTS

In recent years, EPA has learned that caulk containing potentially harmful PCBs was used in many buildings, including schools, in the 1950s through the 1970s. Since the building was constructed in 1998 PCB containing sealants are not likely to be present.

We performed a visual inspection of the building and did not observe suspect PCB containing sealants associated with the building.

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.
