Subject: NPDES Permit #NC0025071, Sampling Reduction Request
To Whom It May Concern:
Our permit is set to expire April 30, 2018. We have already submitted our permit renewal
application on October 3 0, 2017. In addition, we would like to also request that monitoring for
BODS, TSS, NH3-N and Fecal Coliform be reduced under the "exceptionally performing
facilities" criteria to two times per week. The attached data (summarized in the following table)
indicates that the WWTP effluent has greatly exceeded the minimum criteria for reduced
monitoring. The data used for this analysis was for the period of February 2015 — January 2018.
This is more data than was included in the previous application in order to comply with the 3
years of data requirement.

guidance document regarding reduction of monitoring frequencies.
