G Horton suggested they put the question in writing and he would also contract DWQ regional office; and others. Also, Hydrostructures stated they would send CG&L a copy of the reclaimed water system management plan. c. There is an "overlap" in projects creating an opportunity or challenge related to electricaVconduit work at the WWTP. Specifically, contract #1 requires work that may be removed in an upcoming project. Hence there are associated cost issues across projects. G.

In reference to the influent pump station visual alert, I have taken the following action(s). 1. Replaced the light bulb. 2. After further inspection of the float system, I discovered that in order for the visual to activate, the ball float must be allowed to angle upward approximately 45 degrees. When you inspected this system on sight, we only raised the float enough to sound the audible. The system is in working order. 3. I will put this exercise on our "monthly" list of operator checks to ensure this system is consistently checked and in working order.

Terry, Town Manager Town of Pittsboro PO Box 759 Pittsboro, North Carolina 27312 Dear Mr. Terry: Colleen H. Sullins Director 6 Dee Freeman Secretary November 4, 2009 Subject: Draft NPDES Permit Modification Permit NCO020354 Pittsboro WWTP Chatham County By letter of October 1, the Director notified affected dischargers of the Divisions intent to modify their NPDES permits to incorporate new requirements under the Jordan Lake Nutrient Management Strategy and its Wastewater Discharge rule, T15A NCAC 02B .0270. Accordingly, the Division proposes to modify the subject permit and is enclosing the draft modifications for your review and comment. At this time, the Division is submitting a notice to the newspaper of general circulation in Chatham County, inviting public comment on the draft permits for the affected facilities. The notice is scheduled for publication on or about November 6 and initiates a 30-day comment period. Please provide any comments you have regarding the draft permit to this office, in writing, no later than 30 days of receipt of this letter. The draft permit includes the following changes: • Total Phosphorus (TP) Limits. The permit includes three total phosphorus limits: • The mass TP limit from the Robeson Creek nutrient TMDL is a summer limit that applies to the existing discharge to Robeson Creek. Special Condition A.(5.) of the Towns current permit specifies that the limit will be included with the 2011 renewal and will become effective at that time. The Division proposes to add the limit now with a 2011 effective date and to update Condition A.(5.) (now re -numbered as A.(4.)). • The 2.0 mg/ L concentration limit is a year-round limit and applies to the existing discharge to Robeson Creek. Because the mass limits are generally more stringent, it will serve primarily to limit winter discharges to the creek. The concentration limit will remain in effect after the mass limits become effective. • The mass TP limit from the Haw River nutrient TMDL and Jordan Lake Strategy is a year-round mass limit. It is based on the Town's allocation for delivered load and calculated for the 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Location: 512 N. Salisbury St. Raleigh, North Carolina 27604 One Phone: 91M07.63001 FAX: 91M07-64921 Customer Service: "77fi23.6748 NprthCarolina Internet: www.ncwaterquality.org /\ /att�r�'l`J� An Equal Opportunity l AlfimuMive Action Employer l� Y s �/ Mr. William G. Terry, Town Manager Draft NPDES Permit Modification November 4, 2009 Robeson Creek discharge. This limit becomes effective January 1, 2010. The concentration limits remains in effect through December 31, 2009. • Total Nitrogen (TN) Limit. The permit does not include a new limit for total nitrogen at this time. The rule specifies that nitrogen limits will become effective in 2016, and the Division proposes to add those limits to affected permits during the 2011 renewal process. • Nitrogen Optimization. The permit includes a new special condition that re -iterates nitrogen optimization requirements from the point source rule. The rule requires development of an optimization plan that, upon acceptance by the Division, is to be implemented until the nitrogen limits become effective in 2016. It also requires annual status reports until 2016 (the final report will cover calendar year 2015). Some members of the Jordan Partnership undertook a similar effort in 1999. Regardless of its success at individual facilities, most facilities have seen significant changes in their processes or operating conditions since then. The Division does not expect any discharger to conduct an extensive evaluation if it merely repeats the 1999 effort. However, we expect all dischargers to make a reasonable effort to reduce nitrogen discharges until process improvements are completed, as is the intent of the rule. To satisfy this requirement, each discharger should evaluate its treatment facilities and operations or update its previous evaluation(s) and report its findings and recommendations, including, if necessary, an update of its current optimization measures. All facilities will be expected to provide annual reports on the status and effectiveness of the recommended measures. • Additional Special Conditions for Nutrients. The permit includes new conditions that (1) document the nitrogen and phosphorus allocations assigned to the facility and (2) describe how the mass limits will be managed in individual permits and in the event that a group compliance association is formed. These conditions make reference to nitrogen as well as phosphorus and will apply to each nutrient as the respective limits become effective. • Additional Changes. The requirements of Condition A. (6.), Total Phosphorus Compliance Plans, in the current permit have been satisfied and the condition deleted from the draft permit. The special conditions have been re -ordered to put all of the nutrient -related conditions together for easier reference. If you have any questions concerning the draft permit, please contact me at (919) 807-6402 or at mike. templeton@ncdenr.gov. Sincerely, Michael . Templeton, P.E.

There shall be no discharge of floating solids or visible foam in other than trace amounts. Permit No. NCO020354 A.(2.) 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 900/0. The permit holder shall perform at a minimum ua9 rterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase II 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 subsequent 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 THP3B 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/or 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 initial monitoring.

AGII�Ar NCDENR Exvi�xxurt �xo Nmwu R[souvco Draft East Sheet o NPDES Permit Jordan Lake NPDES Dischargers PROPOSED PERMIT ACTION 14 NPDES Permits The Division proposes 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 is to set Total Phosphorus discharge limits in accordance with the Jordan Lake Nutrient Management Strategy: Wastewater Discharge Requirements, T15A NCAC 02B .0270.

Quarterstone Farm WWTP Buffalo Creek Guilford 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. The Strategy calls for improvements in stormwater management (existing and new development), agricultural practices, fertilizer application management, riparian buffers protection, and wastewater treatment. The figure below shows the watershed and the three subwatersheds. The strategy sets nutrient reduction targets for each subwatershed. PROPOSED MODIFICATIONS 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 1 ter must meet nutrient limits based c iese allocations. The limits for both nitrogen and phospnorus are given as annual mass limits. ine phosphorus limits become effective in CY2010, the nitrogen limits in CY2016. The proposed permit modifications affect dischargers with a permitted flow of 0.1 MGD or greater. (Permit NC0003913 for Glen Raven Inc. has been rescinded since work began on the Strategy and so is not affected.) A new Special Condition in each permit identifies the discharge and delivered allocations and the Transport Factor for facility. The permit limit for phosphorus is then based on the 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. The modifications include other, minor changes. Special Conditions and other language with compliance dates that had passed were deleted as a matter of course. And conditions were re- ordered to group the nutrient -related conditions for easier reference. < end of text > NUTRIENT ALLOCATIONS - INITIAL ASSIGNMENTS JORDAN RESERVOIR NUTRIENT MANAGEMENT STRATEGY August2009 -y::a5 � �.m.•p. e,. w *Y � 'o- aT S �p°r. x , wse i v 1u •. 35% TN reduction Transport Allocations - 7N Allocations - TP Permit Owner FacilityMGD �mt TN TP TN at EOP 6 r Avg Conic EOP L TNto Lake Ib r TP at EDP Avg Conic b r C-0P L 7P to Lake r NCO047597 City of Durham South Durham WRF 20.0 75% 67% 185,345 3.04 139,009 14,053 0.23 9.41% NCO025241 Orange Water & Sewer Authority Mason Farm W WTP 14.5 63% 47 % 134,375 3.04 84,656 10,188 0.23 4 N00026051 Durham County Triangle WWTP 12.0 96% 97% 111,207 3.04 106,759 8,432 0.23 8 NCO056413 Whippoorwill LLC Carolina Meadows W WTP 0.35 63% 47 % 3,244 3.04 2,043 246 0.23 116 NCO051314 North Chatham Water & Sewer Company, LLC Cole Park Plaza 0.050 81 % 84% 1,826 '12.00 1,479 304 2.00 256 NCO043257 Nature Trails Association, CLP Nature Trails Mobile Home Park W WTP 0.040 81% 84^/ 1,461 12.00 1,184 244 2.00 205 NCO042803 Birchwood Mobile Home Park Birchwood Mobile Flame Park 0.018 70% 64 % 658 12.00 460 110 2.00 - 70 NCO074446 Hiltop Mobile Home Park Hilltop Mobile Flome Park 0.012 70% 64% 438 12.00 307 73 2.00 47 NCO048429 lCedar Village Apartments lCedar Village Apartments 1 0.005 100% 100% 183 12.00 183 30 2.00 30 46.98 438,736 PS Alloc'n b r EDP 33,680 PS Annen b r FOP 3.04 mg/L TF{Lg 0.23 mg/L TP, Lg ' 12.00 L TF4 Sm 2.00 L TP Sm PS Alloc'n blyrat lake: 336079 PS Alloc'n Ib rat Lake: 23106 ib/yr T14 Lg: 332,467 Ib/yr TP, Lg: 22,498 lb r TP4 Sm: 3,613 lb/ r TP Sm: 608 Cak'd redsn at Lake: 35.

While this result did not place us in violation of our monthly fecal average, it did put us in violation of our weekly fecal average of 400/100mg/l. The week starting Monday August 25th, 2008 our weekly average is 861/100 mg/l. On Tuesday morning September 2,2008 I received the fax from our contract lab, Environment 1, Incorporated, informing us of the result. The fax was actually sent to our Town Hall on Friday afternoon. I personally did not receive the fax until Tuesday morning (do to the Holiday). once I received the fax I immediately contacted your office and talked with Danny Smith. I informed him of the situation and our response to the problem. As you know Wednesday August 27th, 2008 the Town of Pittsboro and parts of Chatham County received a very large quantity of rain (about 4 inches). While everything looked good at the plant and we didn't experience any basin by-passes or breaching, our flows were very high for many hours. Our total flow for Wednesday August 27,2008 was .692 mgd, but we did experience peak flows of about 1.6 mgd for many hours. Just so you are aware we are scheduled to re -furbish our sand filters with the proper manufacturers recommended sand on either September llth or 12th. It has been mentioned that our current sand in these filters is not the correct sand. This causes excessive solids to flow-thru, thus inhabiting the UV's ability to transmit the needed intensity (especially during these large rain events). We will also be pulling, cleaning, and checking all of the UV bulbs in order to ensure that they are functioning properly. I am sure we will talk more about this in the coming days, when you are back in the office. Thanks!

The request was due to the proposed 0.25 MG plant expansion and upgrade and at this point construction plans are currently being drafted. John told me of concerns that he may be able to address now, such as either the imbalanced clarifier flows or the imbalanced sludge blankets. The problem in the clarifier could be a result of the high flow from the airlift return sludge pump. The pump tends to clog or stop pumping when the pumping rate is slowed. A pump that is used in our region that has proven to be very impressive is the "Geyser Pump", which can pump at slow rates thickening the sludge and reducing the turbidity because of the reduced turbulance of the return flow. The Vass WWTP has the Geyser Pump retrofitted to the existing airlift pump and the conversion was completed by the plant staff. Geyser Pump has a good web site and if you are interested I recommend that you talk with the ORC Lamont McNeill @ 910-245-1958 and visit this facility, which is not far from your location. Another idea that was initiated on this installation was to install a dedicated air compressor for this pump. This in turn allowed the main air compressors to be turned off during high flow conditions, allowing the aeration basin sludge to settle and still be able to return sludge from the clarifier, because of the separate dedicated air compressor for the Geyser Return Pump. If the proposed upgrade calls for an additional larger clarifier, you may want to consider building it downstream of the two existing ones. I would recommend the clarifier to be circular, 14-16' deep, and have Stamford Baffles. This clarifier would catch any fines, blanket burps, and really take the load off of the filters. The filter backwash mudwell was discussed as possibly utilizing a programable timer to pump out the mudwell at night during low flow conditions. These are some of the items that we discussed and the reocmmendations and suggestions that were made Page # 2 TOWN OF RANDOLPH VOLLER Mayor WILLIAM G. TERRY Town Manager PAUL S. MESSICK, JR.
