The Walker Group Architecture, Inc September 28th, 2020

WGA Project No. – 2001.IR20

Project Information

The Walker Group Architecture, Inc. was contracted by Camp Lejeune to conduct an lead sampling survey for Buildings/Structures : BA128, BA130, BA137, BA153, BA155, BA157, BA158, BA172, BB45, BB69, BB86, BB117A, BB211, FC240, FC301, FC304, FC318, LCH4011, LCH4038, S944, SAS4127, SAW358A, SAW358B, SAW358C, SAW358D, SAW358J, SAW358K, SBA131, SBA132,. Buildings/Structures LCH4030, S1897, S1906 and SBA152 were also contracted for a survey however, the buildings or structures did not contain any suspect materials to sample after site investigation. 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 06/10/16, 03/17/18, 03/28/1804/25/19, 05/02/19, 04/20/20, 04/21/20, 05/13/20, 05/14/20, and 09/15/20 by Christopher B. Walker (NC Accredited Lead Inspector #110239 expires March 31, 2021. 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.

*Analysis following Lead in Paint by EMSL SOP/Determination of Environmental Lead by FLAA. Reporting limit is 0.010 % wt based on the minimum sample weight per our SOP. Unless noted, results in this report are not blank corrected. 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. Samples received in good condition unless otherwise noted. "<" (less than) result signifies that the analyte was not detected at or above the reporting limit. Measurement of uncertainty is available upon request. The QC data associated with the sample results included in this report meet the recovery and precision requirements unless specifically indicated otherwise.

Definitions of modifications are available upon request.

Samples analyzed by EMSL Analytical, Inc. Kernersville, NC EMSL Lab ID 102564 is accredited by the AIHA Laboratory Accreditation Program (AIHA-LAP), LLC in the Environmental Lead accreditation program for Lead in Paint Chips.

Guidelines for Federal USEPA/HUD Lead in Paint Chips =0.5 % Wt or =1.0 mg/cm² is the EPA definition of a lead-based paint.

Above EPA definition of a lead-based paintAbove RL but below EPA definition of a lead-based paint

Below Method Reporting Limit (RL)

These guidance limits are typically used in most scenarios. More stringent local or project specific guidelines may apply.

Please contact the laboratory for statement of uncertainty data for the utility of properly evaluating these results against any regulatory standards or guidelines.

No responsibility or liability is assumed for the manner in which the results are used or interpreted.
