EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS (continued) Footnotes: 1. U: Upstream at NCSR 1540. Di: Downstream at NCSR 1518. D2: Downstream at NCSR 1327. 2. TN Load is the mass quantity of Total Nitrogen (TN) discharged in a given period of time and requires Total Monthly Flow (TMF). See Special Condition A.(2.), Calculation of TN Load. 3. The monthly average effluent BOD5 and TSS concentrations shall not exceed 15% of their respective influent value (85% removal). 4. TRC Total Residual Chlorine compliance is required for chlorine or chlorine derivative used for disinfection. The Division shall consider all effluent TRC values reported below 50 ug/1 to be in compliance with the permit. However, the Permittee shall continue to record and submit all values reported by a North Carolina certified laboratory (including field certified), even if these values fall below 50 ug/I. 5. Instream samples shall be collected three times per week (3/week) during the months of June through September and once per week (1/week) the remainder of • the year. Instream monitoring is provisionally waived based on the Town of La Grange's membership in the Lower Neuse River Basin Association (LNBA). If at any time during the term of this permit, membership in the LNBA is terminated, the Permittee shall notify the Division immediately, and immediately begin conducting instream monitoring as stipulated in this permit. 6. For a given wastewater sample, 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. 7. Compliance with this limit shall be determined in accordance with Special Condition A. (3.) of this permit, Annual Limits for Total Nitrogen. (b.) There shall be no discharge of floating solids or visible foam in other than trace amounts. A.(2.) CALCULATION OF TOTAL NITROGEN LOADS (a.) The Permittee shall calculate monthly and annual TN Loads as follows: (b.) (i.) (ii.) Monthly TN Load (pounds/month) = TN x TMF x 8.34 where: TN = the average Total Nitrogen concentration (mg/L) of the composite samples collected during the month TMF = the Total Monthly Flow of wastewater discharged during the month (MG/month) 8.34 = conversion factor, from (mg/L x MG) to pounds Annual TN Load (pounds/year) = Sum of the 12 Monthly TN Loads for the calendar year The Permittee shall report monthly Total Nitrogen results (mg/L and pounds/month) in the appropriate discharge monitoring report for each month and shall report each year's results (pounds/year) with the December report for that year. Part I, Page 2 of 4 Permit NC0021644 A.(3.) ANNUAL LIMITS FOR TOTAL NITROGEN (a.) Total Nitrogen (TN) allocations and TN Load limits for NPDES dischargers in the Neuse River basin apply on a calendar year basis. (b.) For any given calendar year, the Permittee shall be in compliance with the annual TN Load limit in this Permit if: (i.) the Permittee's annual TN discharge is less than or equal to its TN Load limit, or (ii.) the Permittee is a co-permittee member of a compliance association. (c.) If the Permittee is not a co-permittee member of a compliance association and the Permittee's cumulative annual TN discharge exceeds the effective TN Load limit in this permit at any point during the calendar year, the Permittee is in violation of its TN Load limit, and each day of a continuing violation shall constitute a separate violation. (d.) The TN Load limit in this Permit (if any) may be modified as the result of allowable changes in the Permittee's TN allocation. (i.) Allowable changes include those resulting from purchase of TN allocation from the Wetlands Restoration Fund; purchase, sale, trade, or lease of allocation between the Permittee and other dischargers; regionalization; and other transactions approved by the Division. (ii.) The Permittee may request a modification of the TN Load limit in this Permit to reflect allowable changes in its TN allocation. Upon receipt of timely and proper application, the Division will modify the permit as appropriate and in accordance with state and federal program requirements. (iii.) Changes in TN limits become effective on January 1 of the year following permit modification. The Division must receive application no later than August 31 for changes proposed for the following calendar year. (iv.) Application shall be sent to: NCDWQ / NPDES Programs Attn: Neuse River Basin Coordinator 1617 Mail Service Center Raleigh, NC 27699-1617 (e.) If the Permittee is a member and co-permittee of an approved compliance association, its TN discharge during that year is governed by that association's group NPDES permit and the TN limits therein. (f.) The Permittee shall be considered a Co-Permittee Member for any given calendar year in which it is identified as such in Appendix A of the association's group NPDES permit. Association roster(s) and members' TN allocations will be updated annually and in accordance with state and federal program requirements. If the Permittee intends to join or leave a compliance association, the Division must be notified of the proposed action in accordance with the procedures defined in the association's NPDES permit. (A) Upon receipt of timely and proper notification, the Division will modify the permit as appropriate and in accordance with state and federal program requirements. (B) Membership changes in a compliance association become effective on January 1 of the year following modification of the association's permit. The TN monitoring and reporting requirements in this Permit remain in effect until expiration of this Permit and are not affected by the Permittee's membership in a compliance association. Part I, Page 3 of 4 Permit NC0021644 A.(4.) TOTAL NITROGEN ALLOCATIONS (a.) The following table lists the Total Nitrogen (TN) allocation(s) assigned to, acquired by, or transferred to the Permittee in accordance with the Neuse River nutrient management rule (T15A NCAC 02B.0234) and the status of each as of permit issuance. For compliance purposes, this table does not supersede any TN limit(s) established elsewhere in this permit or in the NPDES permit of a compliance association of which the Permittee is a Co-Permittee Member.

Transport Factor = 75% (b.) Any addition, deletion, or modification of the listed allocation(s) (other than to correct typographical errors) or any change in status of any of the allocations shall be considered a major modification of this permit and shall be subject to the public review process afforded such modifications under state and federal rules.

It's intended to clarify that exceeding a TN limit on, say, December 1 will be counted as 31 daily violations rather than just one violation of an annual mass limit. This was something both Jeff and the NRCA wanted, so I worked up this language with them and with Jane Oliver from the AG's Office.
