Subject: Pretreatment Review of Enforcement Response Plan (ERP)
Durham County - NPDES Number NCO026051
Durham County
Dear Ms. Brixey,
The Pretreatment, Emergency Response, and Collection Systems Unit (PERCS) of the Division of
Water Resources has reviewed the updated Enforcement Response Plan (ERP) for Durham County. The
updated ERP was in response to the Dental Amalgam Rule (40 CFR 441) and was received by the
Division on February 11, 2020.
The review indicates that the ERP is adequate and meets the requirements of 15A NCAC 02H .0905
and 40 CFR 403.8 (f)(5). Proper implementation is also required by the City's NPDES permit. The
Division expects you to follow this approved ERP for all enforcement actions. Modifications to this ERP
must be approved by the Division.
If you have any questions or comments, please contact Vivien Zhong at [phone] [email:
[e-mail]]. Thank you for your continued support of the Pretreatment Program.
Sincerely,
DocuSigned by:
