Division personnel have reviewed your permit and discovered that the required semi-annual

Enclosed is a technical corrected copy of the permit limits page for NPDES Permit NC0086918.
Please replace the limits page in your current NPDES permit with the corrected limits page and discard
the removed page. This technical correction does not affect any other terms, conditions, or compliance
actions covered by the current permit.
Please note that this permit is not transferable except after notice to the Division. The Division
may require modification or revocation and reissuance of the permit. This permit does not affect the
legal requirements to obtain other permits which may be required by the Division of Water Resources or
permits required by the Division of Land Resources, the Coastal Area Management Act or any other
Federal or Local governmental permit that may be required.

1. Flow estimate shall be based on daily discharge activities to outfall. Duration and flowrate
of discharge should be noted in log book and supported flows reported on DMR.
2. TRC Total Residual Chlorine compliance is required for chlorine or chlorine derivative

record and submit all values reported by a North Carolina certified laboratory (including
field certified), even if these values fall below 50 ug/l.
3. TN = TKN + NO3-N + NO2-N, where TN is Total Nitrogen, TKN is Total Kjeldahl
Nitrogen, and NO3-N + NO2-N are Nitrate and Nitrite Nitrogen respectively.
b. All samples collected should be from a representative discharge event.
c. There shall be no discharge of floating solids or visible foam in other trace amounts.
