PERCS Unit of the Division of Water Resources has reviewed the updated Long Term Monitoring Plan
(LTMP) for the Town of Clayton The LTMP was received by the Division on April 3, 2017.
The review indicates that the 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 your NPDES
permit. Please refer to the Comprehensive Guidance for North Carolina Pretreatment Programs
(Comprehensive Guide) for additional information and examples.
1) LTMP Data Summary: Comprehensive Guide, Appendix 4-e Sample collection and laboratory analysis
must be done as outlined in this LTMP It is also very important to organize and summarize your data.
Example LTMP data summary forms can be found on PERCS website

may request to review tabulated data and to see chain of custody forms and laboratory data sheets.

indicate that the LTMP needs to be modified; however, please be aware that modifications to your
LTMP must be approved by the Division.
