2. Limit takes effect May 1, 2005. Permittee will monitor TRC until the limit takes effect.
3. The discharge from this facility shall not cause turbidity in the receiving stream to exceed 50 NTU. If the
instream turbidity exceeds 50 NTU due to natural background conditions, the discharge cannot cause
turbidity to increase in the receiving stream.
4. See A. (2) for Total Nitrogen monitoring and reporting requirements.
All samples collected should be from a representative discharge event.
There shall be no discharge of floating solids or visible foam in other than trace amounts.

Permit NC0085111
A. (2) CALCULATION OF TOTAL NITROGEN LOADS
a. The Permittee shall calculate monthly and annual TN Loads as follows:
i. Monthly TN Load (pounds/month) = TN x TMF x 8.34
where:
TN = the average TN concentration (mg/L) of the samples collected during the
month
TMF = the Total Monthly Flow of wastewater discharged during the month
(MG/month). If all discharges are not recorded at the facility,
document the calculation(s) used to determine total monthly flow
8.34 = conversion factor, from (mg/L x MG) to pounds
ii. Annual TN Load (pounds/year) = Sum of the 12 Monthly TN Loads for the
calendar year
b. The Permittee shall report monthly Total Nitrogen results (mg/L and pounds/month)
in the discharge monitoring report for that month. The Permittee shall report each
year's annual results (pounds per year) in the December report for that year.
