Subject: Permit No. WQ0030775 Correction
High -Rate Infiltration System
Pender County
Dear Mr. Roberts:
In accordance with a notification received from Amanda Gaines (DWR-Wilmington Regional Office),
we are forwarding herewith the corrected Attachment A for Permit No. WQ0030775, issued March 14,
2013, for the subject facility. The following corrections have been made to the Attachment A:
1. The effluent monitoring frequency for pH was mistakenly listed as "3Xyear" instead of the
low regular "5Xweek", hence, the frequency is corrected.
Please replace Attachment A of the permit No. WQ0030775 that was previously certified on March
14, 2013 with the corrected Attachment A.
If you have any questions regarding this correction, please do not hesitate to contact Chonticha McDaniel
at [phone]. Thank you for your cooperation.
