Dear Ms. Pedley:
Pursuant to N.C. General Statutes Section 143-215.1 and the implementing rules found in Title
15A of the North Carolina Administrative Code, Subchapter 02H, specifically, 15A NCAC
02H .0112(b)(1) and 02H .0114(a), the Director of DWR may reopen a permit to require
supplemental nutrient monitoring of the discharge. Per this letter, the Director is requiring
additional nutrient monitoring at the subject facility's effluent as specified below:
Monitoring for total phosphorus (TP), total nitrogen (TN), total Kjeldahl nitrogen (TKN),
and Nitrite+Nitrate (NO2+NO3) shall be increased to weekly starting on April 1, 2019
and lasting through December 31, 2020. Nutrient monitoring shall revert to sampling
requirements as specified in the facility's NPDES permit starting January 1, 2021. The
additional monitoring results shall be submitted in the Discharge Monitoring Reports.
The additional monitoring will be used to support water quality modeling efforts within the
Cape Fear River Basin. Specifically, the additional monitoring will help ensure that nutrient
loadings from permitted facilities are represented as accurately as possible in the model, which
will include both point and non -point sources.
