Marine Corps Base Camp Lejeune Project # 21-0025

Report Prepared By:

Christopher B. Walker

The Walker Group Architecture, Inc October 20th, 2021

WGA Project No. – 2107.DEMF

Project Information

The Walker Group Architecture, Inc. was contracted by Camp Lejeune to conduct an lead sampling survey for Buildings/Structures: 14, 33, 41, 207, 315, 319, 334, 344, 344, 400, 431, 1042, 1819, AS3906, AS4114, BB269, FC260, H35, M203, M441, RR206, RR207, S58N, SAS888, SAS2849, SAS3601, SBA149, SBB154, SFC254, SG401, SG555, STC953, TC1064, TC1065, TC1066, TC1067, TC1068, TC1069. Structures S58N, SBB154, SAS888, SBA149, STC953 where inspected with no suspect materials found.

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.

Scope of Services

A. The survey was performed on 10/14/21, 10/15/21, 10/27/21, 11/04/21, 11/08/21 by Christopher B. Walker (NC Accredited Lead Inspector #110239 expires June 30th, 2022. 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 safe practices" as outlined by

OSHA.

B. 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.
