Report Prepared By:

Christopher B. Walker The Walker Group Architecture, Inc

August 11th, 2024 WGA Project No. – 2402.FY24

Project Information

The Walker Group Architecture, Inc. was contracted by NRW Engineering to conduct an asbestos sampling survey for Buildings/Structures at Camp Lejeune: 114, 203, 203A, 401, 401A, 528, 728, 1005A, 1014, 1306, 1742A, 1742B, 1742C, AS251, AS849, AS852, AS3906, AS3450, AS3540, AS3990, H206, H207, H208, H209, LCH4034, RR27, RR28, RR108, S185, SAS4215, SBB229, SFC408, SFC499, SFC581, SRR65, SRR66, SHP455A, SRR65, SRR66, SRR93, SRR105, ST13, TC1003, VL60, VL61, VL325, SHP306A, SHP308A, AST27, AST27A, AST27B, LCH4034 Generator Stand. The specified buildings or structures are slated for demolition on board Marine Corps Base. An asbestos survey has been requested prior to disturbance of any potential asbestos containing materials (ACM).

The following buildings/structures were inspected with no suspect asbestos containing materials found during the inspection: AS852, AS903A, AS903B, S185, SAS4215, SRR65, SRR66, SRR93, SRR105, VL60, VL325, SHP306A, SHP308A, AST27, AST27A, AST27B, and LCH4034 generator stand.

Scope of Services

A. The survey was performed on 04/03/20, 04/20/20, 11/04/21, 07/03/24, 07/29/24, 07/18/24, 08/12/24 by Christopher B. Walker (NC Accredited Inspector #12878, expires July 31st, 2025). The sampling was conducted in general accordance with the U.S. Environmental Protection Agency (EPA) requirements as defined in the asbestos Hazards Emergency Response Act (40 CFR Part 763) guidelines (AHERA) and in general accordance with the North Carolina Health Hazards Control Unit (NCHHCU).

B. The survey was conducted to identify the presence of asbestos containing materials (ACM) prior to building demolition.

C. The buildings were assessed to determine homogenous areas (groups of materials appearing to have been installed in the same general time period and uniform in color and texture).

D. As per AHERA, sufficient samples were collected from random locations of each homogenous area, with the number of samples based on the following criteria:

a. Thermal Insulation Materials (piping, breeching, boiler insulation, etc.) – A minimum of (3) samples are required. Patch areas (less than 6 square or liner feet) may have (2) sample collected.

b. Surfacing Materials (plaster, fireproofing, etc.) – A minimum of (7) samples are to be taken for areas greater than 5,000 square feet, five (5) samples for areas greater than 1,000 square feet, but less than 5,000 square feet, three (3) samples for areas less than 1,000 square feet, two (2) samples for patching materials.

c. Miscellaneous Materials (flooring, adhesives, roofing, wallboard, etc.) – A minimum of (2) samples are required.

If any one sample of a material from a homogenous area is found to be positive, then that material is considered positive, regardless of results of other samples of that material, within that area.

Samples

A. The Walker Group Architecture collected suspect samples and shipped them to EMSL Analytical, Inc. (NVLAP Accredited Laboratory 102104-0) for PLM (polarized Light Microscopy) analysis. In an effort to reduce cost, the Walker Group instructed the laboratory to Stop Analysis at the first positive sample for each suspect material HGA and not to analyze the remaining samples from the same HGA.

Disposal

A. In accordance with the NCHHCU regulations, asbestos containing materials (ACM) waste should be taken to an approved landfill. All demolition/renovation work must be performed in accordance with NESHAP asbestos regulations, 40CFR61, Subpart M, and OSHA Regulations 29 CFR 1926.1101. Any disturbance should be conducted in accordance with federal, state, and local regulations.

Recommendations

A. Any demolition/renovation work in which ACM is disturbed must be in compliance with, EPA, OSHA and the state of North Carolina regulations. Abatement work shall be conducted by NC Accredited asbestos workers under the supervision of a NC accredited asbestos supervisor. The contractor conducting asbestos abatement activities must notify the North Carolina Department of Health and Human Services (HHS) ten (10) days prior to the disturbance of ACM if it is friable and greater than or equal to 160 square feet, 260 linear feet or 35 cubic feet.

B. If additional suspect materials are discovered during demolition/renovation, they should be classified presumed to be asbestos-containing until sampling by a state of North Carolina licensed Asbestos Building Inspector personnel and analysis by a NVLAP-Accredited and state of North Carolina licensed laboratory can be performed.

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.

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 .
