RE: Recommended Sampling Plan
Vance County Transfer Station
Permit# 9102T-TRANSFER-1997
Vance County
FID 1833595

Dear Mr. Pfleger:

The Solid Waste Section (Section) has reviewed the Recommended Sampling Plan (FID 1833594)
submitted on behalf of GFL Environmental by Smith + Gardner, Inc. (S+G). The sampling plan was
submitted in response to a March 7th 2024 compliance inspection where standing water was
observed near the southern end of the transfer trailer loading bay.

S+G proposes to collect two discrete soil samples (SS-1 and SS-2) at depths ranging from one to
two feet below ground surface in the area of concern following impacted soil excavation. Soil
samples will be analyzed for 40 CFR 258 Appendix I constituents, total phosphorus, sulfate,
nitrate, and pH. S+G will compare the results of SS-1 and SS-2 samples to background soil
sample results from previous investigations and the Preliminary Soil Remediation Goals.
Additional analysis using the Synthetic Precipitation Leaching Procedure may be used if initial
analytical results indicate the presence of impacted soils.

The Section approves the sampling plan and S+G may implement it as proposed. Please contact
me at 919-707-8288 or [e-mail] if you have any questions or concerns regarding
this correspondence. Thank you in advance for your cooperation in this matter.

Sincerely,

Ervin Lane
Hydrogeologist
