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 a lead sampling survey for Buildings/Structures: 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 Camp Lejeune. The survey was conducted to determine if building components were coated with lead-based paint.

The following buildings/structures were inspected with no suspect asbestos containing materials found during the inspection: AS852, AS903A, AS903B, SAS4215, SFC409, SFC499, SFC581, SRR93, SRR105, VL60, SHP306A, SHP308A, 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 Lead Inspector #110239 expires February 28th, 2025. Samples were collected from areas defined by the scope of work.

Findings

A. The Walker Group Architecture collected paint chip samples from each surface visibly coated with a different color of paint and delivered them to EMSL Analytical, Inc. (AIHA ELLAP lab code no. 102564) for analysis for lead content by Flame AAS (SW 846 3050B*/7420) in accordance with EPA 3050B/Modified/7000B. OSHA 29 CFR

1926.62 defines any detectable level of lead in paint a concern when renovations/demolitions will impact lead coated surfaces.

B. The detection limit is determined by weight of the sample, which is typically 0.01%.

See attached Lab Results for additional information.

Recommendations

A. Any demolition/renovation work in which lead coated surfaces are disturbed must be in compliance with all Federal, State, and Local regulations. All work should be conducted by workers trained in "lead

B. safe practices" as outlined by OSHA.

C. If additional suspect materials are discovered during demolition/renovation, they should be classified presumed to contain lead-based paint until sampling by a state of North Carolina licensed Lead Inspector personnel and analysis by an Accredited and state of North Carolina licensed laboratory can be performed.

See attached for Plan Locations, Lead Laboratory Results, and Chain of Custody.
