Box 3136 Greensboro, NC 27402-3136 Subject: NPDES Permit Modification Permit Number NC0024325 City of Greensboro — North Buffalo Creek WWTP Guilford County Dear Ms. Groome: Division personnel have reviewed and approved your application for minor modification of the subject permit. Accordingly we are forwarding the attached modified permit page. Please remove the existing "Effluent Limitations and Monitoring Requirements" page and replace it with the one attached to this letter. This modification reduces the effluent monitoring frequencies for Biochemical Oxygen Demand (BOD5), Total Suspended Solids (TSS), Ammonia Nitrogen (NH3-N) and Fecal Coliform from daily (5/week) to 2/week monitoring. The modification was based upon an evaluation of three years of facility effluent monitoring data. The facility's performance satisfies the criteria established in the "DWQ Guidance Regarding the Reduction of Monitoring Frequencies in NPDES Permits for Exceptionally Performing Facilities" as approved by the Director of the Division of Water Quality on October 22, 2012, and justifies reduced monitoring for these parameters. The modified monitoring frequencies will become effective on June 1, 2013. This modification is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently amended). 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 Quality 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. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Location: 512 N.

Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently amended). The following changes have been incorporated into this permit renewal: • The Jordan Lake Nutrient Management Strategy rules adopted in Aug. 2009 prompted a stream reclassification for North Buffalo Creek from C; NSW to WS-V; NSW. See the Supplement to Permit Cover Sheet. • Cr, Ni, Se, Fe and chloride sample results showed no reasonable potential to violate Water Quality Standards (WQS) and were removed from the permit. • Mercury sampling results showed reasonable potential to violate WQS. Mercury monitoring remains in the permit with a daily maximum limit of 36 ng/L and a monthly average limit of 12 ng/L. Chronic and acute limits were required by US EPA Region N. Monitoring was reduced to quarterly. • Cu and Zn sampling results showed reasonable potential to violate WQS, however, they are action level parameters and limits are set in conjunction with toxicity test results. North Buffalo WWTP is passing its toxicity tests so limits are not necessary. Both parameters remain in the permit and sampling was reduced from monthly to quarterly. • All CN samples reported by the City were less than 20 ug/L, therefore, the limits for CN were removed and monitoring was reduced to quarterly in accordance with Division guidance. The City should consider using improved equipment or sampling techniques to achieve a lower PQL. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Location: 512 N.

Since this is not a required Pretreatment Long Term Monitoring Program parameter it will remain in the permit with a reduced sampling frequency of quarterly and no limitation. • A second footnote has been added to Section A. (2.) Combined Limitations for Nutrients— Outfall C01 to recognize Session Law 2011-394, H.B. 119. • Section A. (4.) on the Effluent Pollutant Scan now designates the three years in which the scans are to be performed. Please review. • Section A. (7.) (d.) on Combined Annual Delivered Loads (Ib/yr) for Total Phosphorus and Total Nitrogen requests that the Combined Delivered Loads be labeled in the DMR report. • Section A. (8.) was added to address the City of Greensboro's Nitrogen Optimization Plan. Please note that the receiving stream is listed as an impaired waterbody on the North Carolina 303(d) Impaired Waters List. Addressing impaired waters is a high priority with the Division, and instream data will continue to be evaluated. If there is noncompliance with permitted effluent limits and stream impairment can be attributed to your facility, then mitigative measures may be required. If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this decision shall be final and binding. 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 Quality 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.
