Re: Work Plan
Stockpile Soil Sampling
Former Abernethy Lumber
E. Craighead Road and Philemon Avenue
Charlotte, North Carolina
Brownfields Project No. 18015-40-060
H&H Job No. SHR-001

Dear Carolyn:

1.0 Introduction
On behalf of Philemon NoDa Partners, LLC, Hart & Hickman, PC (H&H) has prepared this
stockpile soil sampling work plan for the former Abernethy Lumber Brownfields property located at
E. Craighead Road and Philemon Avenue in Charlotte, Mecklenburg County, North Carolina (Site).
The Site is in the North Carolina Department of Environmental Quality (DEQ) Brownfields Program
(Brownfields Project #18015-40-060). Grading and construction activities are currently underway at
the Site in accordance with the DEQ-approved Environmental Management Plan (EMP).

As we’ve discussed, H&H proposes to conduct stockpile soil sampling activities at the Site to
determine if the stockpiled soil is suitable for use in future landscaped and/or exposed areas. The
soil stockpile contains approximately 4,000 cubic yards of material cut from the far western portion
of the Site during construction of the temporary sediment basin. Based on current construction

plans, approximately 4,000 cubic yards of soil will be required to fill the planned landscaped areas at
the Site from zero to two ft below ground surface (bgs). Analytical results will be compared to the
DEQ Inactive Hazardous Sites Branch (IHSB) Residential Preliminary Soil Remediation Goals
(PSRGs) and Site-specific background concentrations for metals. The stockpiled soil will be
deemed suitable for use in exposed areas at the Site if analytical results are below the Residential
PSRGs and/or Site-specific background concentrations for metals.

The proposed assessment activities will be performed in general accordance with DEQ’s IHSB
Guidelines for Assessment and Cleanup (Guidelines) dated October 2015 and most recent version of
the U.S. Environmental Protection Agency (EPA) Region IV Science and Ecosystem Support
(SESD) Field Branches Quality System and Technical Procedures guidance. Details concerning
these activities are provided below.

2.0 Sampling Activities

Stockpile Soil Sampling
To evaluate the suitability of the stockpiled soil at the Site, H&H proposes to sample the soil
stockpile at a rate of one sample per 1,000 cubic yards. Therefore, four samples will be collected
from the soil stockpile for laboratory analysis. In accordance with the DEQ-approved EMP, final
grade samples will be analyzed for volatile organic compounds (VOCs) by EPA Method 8260, semi-
VOCs (SVOCs) by EPA Method 8270, and hazardous substance list (HSL) metals plus hexavalent
chromium by EPA Methods 6020/7179/7199. VOCs will be collected as grab samples using a
decontaminated stainless-steel hand auger. SVOCs and metals will be collected as composite
samples using a decontaminated stainless-steel hand auger. The composite samples will consist of at
least five sample aliquots that are combined to form one sample for laboratory analysis. The soil
samples will be placed in dedicated laboratory-supplied sample containers and then shipped to a
North Carolina-certified laboratory under standard chain of custody protocols.
