Dear Mr. Rich:
ROY COOPER
Governor
MICHAEL S. REGAN
Secretary
S. JAY ZIMMERMAN
Director
PERCS Unit of the Division of Water Resources has reviewed the updated Long Term Monitoring Plan
(LTMP) submitted by the City of Whiteville. The LTMP was initially received by the Division on April 25,
2017, followed by several revisions received on different dates since then.
The review, with the most recent corrections, indicates that the updated LTMP is adequate and meets
the requirements needed to establish a site-specific Headworks Analysis (HWA). Proper implementation
of an LTMP is also required by Part IV (C) of your NPDES permit.
1. LTMP Data Summary: Comprehensive Guide, Appendix 4-8 sample collection and laboratory analysis
must be done as outlined in LTMP. It is also very important to organize and summarize your data.
Example LTMP data summary forms can be found on our website (web address listed in footer of this
letter).
2. Division Review of Data: As your LTMP 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. LTMP Modifications: Interpretation of monitoring data or changes in operation at your POTW may
indicate that the LTMP needs to be modified; however, please be aware that modifications to your
LTMP 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 [phone] [[e-mail]] or Deborah Gore,
Unit Supervisor at [phone] [deborah.gore@ncdenr gov].
