Surry County
Dear Mr. Marion,
The Pretreatment, Emergency Response, and Collection Systems Unit (PERCS) of the Division of
Water Resources has reviewed the updated Enforcement Response Plan (ERP) for the City of Mount
Airy. The updated ERP was in response to the Dental Amalgam Rule (40 CFR 441) and was received by
the Division on January 13, 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 Monti Hassan at [phone] [email:
Monti.Hassan(a�ncdenr.gov]. Thank you for your continued support of the Pretreatment Program.
Sincerely,
DocuSigned by:
