Sullins Director July 9, 2010 Dee Freeman Secretary Subject:. NPDES Permit Modification Permit NCO021211 Graham WWTP Alamance County Consistent with the Director's October 1, 2009, letter of intent to modify NPDES permits affected by the Jordan Reservoir Nutrient Management Strategy rules and in consideration of public comments on the subsequent draft permit modifications, the Division is forwarding herewith the revised NPDES permit for the Graham WWTP. This permit 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. The Division received no comments on the City's draft permit during the initial public comment period and is issuing the permit with the proposed modifications. However, we did receive comments from several permittees, including the City, regarding the standard permit conditions (Parts II, III, and IV) in the draft permits. In response, Jeff Poupart of the Point Source Branch has worked with other programs within the Division and with EPA Region 4 staff to evaluate and address those comments. The final permit includes the resulting version of the standard conditions. We regret any inconvenience this delay may have caused. Implementation of Total Phosphorus (TP)Limits. The Jordan Reservoir Wastewater Discharge Requirements (T15A NCAC 02B .0270) established annual mass phosphorus limits for fourteen treatment facilities, to become effective with calendar year 2010. Thus, even though the effective date of this permit modification is August 1, 2010, the new limits became effective January 1, 2010, by rule and apply to calendar year 2010 in its entirety. 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 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 One Location: 512 N.

PROVISIONAL WAIVER OF INSTREAM MONITORING REQUIREMENTS Instream monitoring requirements in this NPDFS permit shall be provisionally waived so long as the Permittee remains a member of the Upper Cape Fear River Basin Association and the Association continues to function as approved by the Division and Environmental Management Commission. If the Permittee does not participate in the Association or if the Association ceases to function, the instream monitoring requirements in this permit become effective immediately; and the Division may reopen this permit by administrative letter to establish additional instream monitoring requirements it deems necessary to adequately characterize the effects of the discharges on water quality in the receiving stream. Permit No. NCO021211 A.(3.) CHRONIC TOXICITY PERMIT LIMIT (Quarterly) The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 14%. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase H Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be performed during the months of March, June, September and December. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes. If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic Whole. Effluent -Toxicity Test Procedure" (Revised - February 1998) or subsequen t.versions. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP313 for the Chronic Value. Additionally, DWQ Form AT- 3 (original) is to be sent to the following address: NCDENR/ DWQ/ Environmental Sciences Section 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Section at the address cited above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will 'be required during the following month. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re- opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring.

I VVA AT4 0011% �0 NCDEHR CARouxA CEPARTmwr cw ErmRONMCNT AND Kxru*AL Rasma=5 Final Fact Sheet - NPDES Permit Jordan Lake NPDES Dischargers PROPOSED PERMIT ACTION 14 NPDES Permits In November 2009, the Division proposed to modify fourteen (14) NPDES permits for municipal and domestic treatment facilities in the Jordan Lake watershed of the Cape Fear River Basin. The purpose of the modifications was to set Total Phosphorus discharge limits in accordance with the Jordan Lake Nutrient Management Strategy: Wastewater Discharge Requirements, T15A NCAC 02B .0270. JORDAN LAKE NUTRIENT MANAGEMENT STRATEGY The Jordan Lake Nutrient Management Strategy is a comprehensive set of rules and Session Law that became effective August 11, 2009. The Strategy aims to restore and maintain water quality, protect the lake's classified uses, and maintain or enhance protections currently implemented by local governments in existing water supply watersheds. Me Strategy calls for improvements in stormwater management (existing and new development), agricultural practices, fertilizer application management, riparian buffers protection, and wastewater treatment. The Strategy establishes nitrogen and phosphorus allocations for all existing wastewater dischargers that treat nutrient -bearing wastes. For point sources, it specifies that facilities with a permitted flow of 0.1 MGD or greater must meet nutrient limits based on these allocations. The limits for both nitrogen and phosphorus are given as annual mass limits. The phosphorus limits become effective in CY2010, the nitrogen limits in CY2016. The figure below shows the watershed and the three subwatersheds. The strategy sets nutrient reduction targets for each subwatershed. PROPOSED PERMIT MODIFICATIONS The proposed permit modifications affect the fourteen dischargers affected by the new rule, and these are listed below. (The list once included a fifteenth permit, NC0003913 for Glen Raven Inc., but that has been rescinded since work began on the Strategy and so is not listed.) The modifications add a new Special Condition to each permit to identify the discharge and delivered allocations and the Transport Factor for the permitted facility. The permits include the new annual mass discharge limits for phosphorus, equal to each facility's TP discharge allocation. The Division intends to add nitrogen limits during the 2011 permit renewals. The attached table lists all facilities in the Jordan Lake watershed that received nutrient allocations under the Wastewater Discharge Requirements rule. It shows the allocations, transport factors, and permitted flow for each facility. It also shows the equivalent concentrations for the TN and TP allocations, that is, the concentration that the facility must reach to meet its mass limit at full permitted flow. Some of the modifications include other, minor changes. For example, conditions were re- ordered to group the nutrient -related conditions for easier reference.

Quarterstone Farm WWTP Buffalo Creek Guilford PUBLIC COMMENTS Several permittees submitted comments specific to their permits. Among these: OWASA noted that special monitoring for cyanide and mercury had been completed and that sample type for ongoing monitoring was incorrectly shown as Composite; the special condition was removed and sample type corrected. Durham County pointed out that the optimization requirement does not apply to its Triangle facility because it has already made capital improvements to meet the new Jordan nutrient limits. The condition was removed. EPA had no comments or objections regarding the draft permits; neither did DEH. No other public comments were received. When one permittee questioned one of the standard permit conditions, it came to light that the permits been mailed with an out-of-date version of the boilerplate. The Division distributed the current version, which was itself a 2009 update, and granted another 30-day comment period. This prompted closer scrutiny, and several permittees then took issue with other of the standard conditions, particularly the pretreatment conditions in Part IV. Jeff Poupart of the Point Source Branch worked with other programs within the Division and with EPA Region 4 staff to evaluate and address the comments received. This led to a newly revised version of the standard conditions, which was included in the final permits. Greensboro and Burlington asked for permit limits combining, in each case, the City's two allocations into a single over -arching limit. Further action was delayed pending the outcome of the standard conditions issues. FINAL ACTION Ten of the fourteen permits will be issued as proposed, except that they will have the newly revised standard conditions and some will be revised based on comments. The Greensboro and Burlington permits will be revised to include joint limits and will be sent to public notice again. < end of text > R.

I have the following comments as follows: 1. ( Page 14 Part IV Section A) The definition of Significant Industrial User contains a 5% MAHL provision. The Triennial review proposed changes will vastly increase new SIU determinations because the MAHL loadings will become extremely smaller. The 5% MAHL is a North Carolina requirement not an EPA requirement. EPA requires only an SIU determination when a 5% hydraulic or organic capacity is reached. 2. ( Page 15 Section C (2) c) This section proposes investigation of all discharges that have the potential to impact the pretreatment program. In addition, these dischargers must be reported within 24 hours. Reporting potential discharges may be hard to determine. Reporting a spill can be easily done, but trying to report potential problems needs to be clarified. 3. ( Page 16 Section D 2) The POTW shall implement an Industrial Waste Survey which includes all users and industrial users. The characteristics and amount of pollutants must also be submitted in the survey. This can cause an excessive burden on municipalities to include all users in the survey. This survey could become more user friendly if best professional judgment could be used for certain commercial establishments such as hair salons, business offices, and retail stores. Thank you for your invitation to comment on the standard conditions for NPDES Permit NCO021211.

Sullins Director October 1, 2009 Dee Freeman Secretary Subject: Notification of Intent to Modify NPDFS Permit NCO021211 to Incorporate Jordan Lake Nutrient Requirements Graham WWTP Alamance County Governor Bev Perdue recently signed legislation to complete passage of rules for the Jordan Lake Nutrient Management Strategy. The Strategy includes a Wastewater Discharge rule (T15A NCAC 02B .0270) that applies to your wastewater treatment facility. Pursuant to Sub -Item (6)(d) of that rule, I am writing to notify you of (1) the nutrient allocations assigned to your facility and (2) the Division of Water Quality's intent to modify the facility's NPDES permit to include nutrient limits as provided in the rule. I also wish to remind you of other provisions of the rule that require your prompt attention. This letter addresses only certain provisions of the Jordan Lake Wastewater Discharge rule. I encourage you to familiarize yourself with the remainder of this rule. Nutrient Allocations. The Wastewater Discharge rule establishes the maximum loads of nitrogen and phosphorus that can be released from wastewater treatment facilities into the Jordan Lake watershed. The rule specifies that these wasteload allocations are to be divided among the existing facilities in proportion to their 2001 permitted flows (with certain exceptions). Your facility has been assigned nitrogen and phosphorus allocations. The allocations are expressed as annual mass loadings delivered to the lake. Due to foreseeable losses between the discharge point and the lake, they are also expressed as the equivalent discharge loads at the point of discharge. The delivered and the corresponding discharge allocations assigned to your facility are as follows: NCO021211 Delivered Allocation (lb/yr) Transport Factor (%) Discharge Allocation (lb/yr) Total Nitrogen 45,615 81 56,315 Total Phosphorus 5,026 1 71 7,079 2001 Permitted Flow: 3.5 MGD 1617 Mail Service Center, Raleigh, Borth Carolina 27699-1617 Location: 512 N.

The new rule specifies that facilities with permitted flows at or above 0.1 MGD, including yours, will be subject to effluent limits for nitrogen and phosphorus. The effluent limits will equal the facility's discharge allocations. The new phosphorus limits become effective beginning with calendar year 2010. Nitrogen limits become effective beginning with calendar year 2016. It is the Divisions intent to modify the affected permits by the end of 2009 to include the new phosphorus limits. We will draft permit modifications for the affected facilities in the coming weeks. As with any such permit action, the proposed modifications will be subject to public review, and we will provide you with a copy of the draft permit at that time. The Division will add nitrogen limits during the 2011 permit renewals, with a compliance date of 2016. Process Optimization. The rule specifies that no later than six months after its effective date, each discharger with a permitted flow greater than or equal to 0.5 MGD must "evaluate its treatment facilities and operations and identify further opportunities to improve and minimize nitrogen reduction in the existing facilities...; and submit a report to the Division documenting its findings, proposing optimization measures, and describing expected results." Please provide three copies of your report to the Division at the following address no later than February 11, 2010: Division of Water Quality Surface Water Protection Section, Point Source Branch Attn: Jordan Lake Coordinator 1617 Mail Service Center Raleigh, NC 20699-1617 Each discharger must implement the proposed measures no later than six months after the Division accepts the report and continue until such time as the facility is upgraded for nitrogen removal. The affected dischargers must also submit annual progress report to the Division for a period of five years.
