Subject: Pretreatment Review of Headworks Short Term Monitoring Plan
Dutchman Creek WWTP (NPDES#: NC0021491)
Program: Town of Mocksville
Davie County
Dear Ms. Brailey:
PERCS Unit of the Division of Water Resources has reviewed the updated Short Term Monitoring Plan
(STMP) for the Town of Mocksville. The STMP was initially received by the Division on August 28, 2018,
from Envirolink, Inc., on behalf of the Town,followed by revisions received on November 11, 2018.
The review indicates that the STMP is adequate and meets the requirements needed to establish a site-
specific Headworks Analysis(HWA). Proper implementation of an STMP is also required by Part IV,Section
D of your NPDES permit.
1. STMP Data Summary: Sample collection and laboratory analysis must be done as outlined in this
STMP. It is also very important to organize and summarize your data. Example STMP data summary
forms can be found on PERCS website.
2. Division Review of Data: As your STMP data is accumulated, organized, and analyzed, the Division
may request to review tabulated data and to see chain of custody forms and laboratory data sheets.
3. STMP Modifications: Interpretation of monitoring data or changes in operation at your POTW may
indicate that the STMP needs to be modified; however, please be aware that modifications to your
STMP must be approved by the Division.
Thank you for your continued cooperation with the Pretreatment Program. If you have any questions or
comments, please contact Monti Hassan at(919) 707-3626 [email: [e-mail]].
S'ncerely,
Monti Ha san V
