RE: Notification of Detections above NC 2L or SWS GWPS Standards
First Semiannual Sampling Event of 2016
Granville County – Oxford Unit 1 Landfill, Permit No. 3901-CDLF-1997
JOYCE Project No. 00660.1601.12, Task 05

Dear Ms. Drummond:

On behalf of Granville County, Joyce Engineering is submitting this notification of exceedances of
15A-NCAC-2L (NC-2L) groundwater standards at the Granville County – Oxford Unit 1 Landfill, Permit
No. 3901-CDLF-1997, in accordance with Title 15A, Chapter 13, Subchapter 13B, Section .1634 (g) of
the North Carolina Solid Waste Management Regulations. The first semiannual sampling event of 2016 at
the Oxford Unit 1 Landfill took place on February 17-18, 2016.

Iron and manganese concentrations in several monitoring wells were reported above the NC 2L
Standards. An alternate source demonstration for iron and manganese for the site was approved by the
SWS in a letter dated June 9, 2011.

Vinyl chloride in MW-5R was reported above the NC 2L Standard at 5.4 µg/L. In response to the
historical exceedances, Granville County has implemented an approved Corrective Action Plan (CAP), as
required by the NC DENR. The results are consistent with historical data.

A complete report documenting the activities and results of the first semiannual compliance
monitoring event of 2016 will be submitted to the NC DENR separately. If you have any questions or
need additional information, please feel free to contact me at [phone].

Sincerely,
JOYCE ENGINEERING
