(3) CHRONIC TOXICITY PASS/FAIL PERMIT LINHT The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 36%. The permit holder shall perform at a minimum,guarterlu 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 February, May, August and November. 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 THP313 for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address: Attention: North Carolina Division of Water Quality 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 Branch 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. r Permit NC0023868 A.

The additional monitoring will be to support water quality modeling efforts within the Cape Fear River Basin, and shall be consistent with a monitoring plan developed jointly by the Division and affected stakeholders. A. (5) CALCULATION OF MASS LOADS a. The permittee shall calculate monthly and annual TN (or TP) loads as -follows: i. Monthly TN (or TP) Loads = TN (or TP) x TMF x 8.34 Where: TN (or TP) = the average Total Nitrogen (or Total Phosphorus) concentration (mg/L) of the composite samples collected during the month. TMF = the total monthly flow of wastewater discharged during the month (MG/mo) 8.34 = conversion factor, from (mg/L x MG) to pounds ii. Annual TN (or TP) Load (lb/yr) = Sum of 12 monthly TN (or TP) Loads for calendar year. b. The permitte shall report monthly total nitrogen and total phosphorus results (mg/L and lb/mo) in the appropriate discharge monitoring report for each month and shall report each year's results, (lb/yr) with the December report for that year.

The treatment plant includes chemical and biological phosphorus removal and has a capacity of 12 MGD. It consists of a bar screen, grit chamber, equalization basin, primary clarifiers, activated sludge/activated carbon aeration (Powdered Activated Carbon Treatment process), BNR tanks, final clarifiers, tertiary sand filters, chlorination and dechlorination, sludge thickeners, digesters,, and lime stabilization. A renewal application was submitted on November 23, 2005. There have been no major changes since the last permit renewal. The city has an approved pretreatment program with 8 significant industrial users and one categorical. industrial user. The permit requires the city to continue to operate its approved pre-treatment program. Basin plan/303(d) This facility discharges to the Haw River in subbasin 03-06-02 in the Cape Fear River Basin. The receiving stream is classified C-NSW. This section of the Haw River is impared for biological integrity due to fecal coliform violations. Turbidity was also exceeded in 10% of samples. A TMDL, completed in 2004 and approved in January 2005, recommended a 61 percent reduction in Total Suspended Solids and a 77 percent reduction in fecal coliform bacteria from both point and nonpoint sources to meet the turbidity and fecal coliform bacteria standards. Further analysis is required to distribute the loads among non -point and point sources.. Data Review The following is a summary of data from DMRs from January 2004 to December 2005: Flow BOD TSS TN TP Ammonia TRC 04-05 Average 5.045 MGD 2.88 mg/L 4.2 mg/L . 14.6 mg/L 0.46 mg/L < 0.5 mg/L 92 pg/L The facility had no NOVs or limits violations. Fact Sheet NPDES NCO023868 Renewal Page 1 Toxicity test — The permit requires quarterly chronic test (Ceriodaphnia) at 36 % IWC..They passed all the toxicity tests in the past 5 years. The City of Burlington is a member of the Upper Cape Fear River Coalition and instream monitoring requirements of the NPDES permit are therefore waived as long as the membership in the association continues. Correspondence The Winston-Salem Regional Office (RRO) conducted several site visits during this permit term to evaluate compliance. A Staff Report was also prepared in conjunction with the permit renewal. WSRO finds the facility to be in compliance with the NPDES permit and recommends renewal. Reasonable Potential Analysis (RPA) The Division conducted a reasonable potential analyses to determine the reasonable potential for toxicants to be discharged by this facility, based on DMR and pre-treatment data from December 2003-December 2005. The RPA was completed for arsenic, cadmium, copper, cyanide, lead, mercury, molybdenum, nickel, silver, selenium, and zinc. Results suggest no reasonable potential for all parameters except copper and zinc. Copper and zinc are action level standard parameters and will continue to be monitored on a monthly basis. Monitoring and limits for cyanide, chromium and silver will be removed from the permit. Silver and cyanide were not detected in the effluent and chromium shows no reasonable potential. These parameters will continue to be monitored through the LTMP. Cape Fear Nutrient Permitting strategy For the 2006 permit renewal cycle the Division developed a permitting strategy to address nutrient concerns in the Cape Fear River Basin. This strategy is being applied at permit renewal to existing discharges on the basin. The strategy calls for additional nutrient monitoring and reporting to support the efforts of the Modeling and TMDL Unit in developing special studies and TMDL projects. Dischargers in the Jordan Lake watershed will monitor TN and TP 3 times per week, report nitrogen species, and report TN and TP as both concentration and mass loads. The permit also includes a re -opener special condition. In the event that the Environmental Management Commission adopts a nutrient management strategy or the EPA approves a TMDL in the coming permit term, the condition allows the Division to re -open affected permits to set nutrient limits and related conditions accordingly. SUMMARY OF PROPOSED CHANGES The draft permit includes he following modifications: • Weekly average limits for ammonia of 12 mg/L (summer) and 24 mg/L (winter) were added to the permit. As per federal regulations the permit has to include monthly and weekly average limits. • A daily maximum limit of 28 µg/L total residual chlorine was added to the. permit. A water quality standard of 17 µg/L has been adopted for total residual chlorine. The limit is capped at 28 µg/L. • Annual effluent pollutant scan — All major municipal permits are required to do an annual pollutant scan to collect data required for permit renewal. • Nutrient monitoring as per Cape Fear Nutrient Permitting Strategy.

Box 1358 Burlington, N.C. 27216-1358 STEPHEN R. SHOAF DIRECTOR OF UTILITIES Ms. Teresa Rodriguez NCDENR/DWQ/ NPDES Permit Unit 1617 Mail Service Center Raleigh, NC 27699-1617 RE: Draft NPDES Permit No. NCO023868 East Burlington WWTP City of Burlington, Alamance County Dear Ms. Rodriguez: July 24, 2006 Ed) J U L 2 7 2006 DENR - WATER QUALITY POINT SOURCE BRANCH I have reviewed the draft NPDES permit NCO023868 for the East Burlington WWTP and have the following questions and comments. • The City of Burlington will have to purchase equipment and train staff at the plant to sample and analyze for low-level chlorine residual. The South Burlington WWTP draft permit states that the low-level chlorine residual limit will take effect 18 months after the effective date of the final permit. The East Burlington WWTP draft permit does not mention a similar delay in implementing the limit. The City requests clarification and confirmation that the requirement for low level chlorine residual monitoring and the permit limit begins after 18 Ck months from the effective date of the permit. We will have to test our procedures and methods prior to the limit being effective, and will need the lead time without the monitoring requirement in order to set up our program. • The City of Burlington understands the addition of Weekly Average limits for ammonia. A review of historical data does not indicate that we will have prolonged difficulty meeting these limits. Nitrification is a biological process and there may be times when the biological conversion of ammonia to nitrite and nitrate will be disrupted. We will try to minimize those events. • The City noticed that the monitoring for conductivity has been changed to "Daily". Is that a typo on the limits page? There will not be much knowledge gained from daily monitoring of conductivity. The old permit has a footnote that explains that daily is three times per week June — September and one time per week for the remainder of the year. This same footnote appears on the draft South Burlington permit. Also Conductivity is listed as a composite sample on the East plant permit and as a grab sample on the South plant permit. Shouldn't those methods be the same? • On the "Supplement to the Permit Cover Sheet" the list of treatment facility components includes the addition of carbon. We do not currently add carbon to the wastewater. There have been a substantial number of textile plants that have gone out of business in Burlington. The effectiveness of carbon has not been demonstrated at our plant, given the current composition of our wastewater. The City of Burlington understands that as the rules for the nutrient control strategy for the Jordan Lake Watershed are developed, approved, and implemented there will be changes in the requirements (re -opener clause) for the various entities within the watershed. We will take that opportunity to provide comments as necessary. What is not clear is the reasoning for changing the nitrogen and phosphorus monitoring to a frequency of 3 times per week. According to the documentation used in development of the Jordan Lake Watershed nutrient management strategy the contribution of nitrogen loading at the lake is only 28% from point sources on the Haw River Arm vs. 72% nitrogen loading from the non -point sources. Also, these same documents show that the contribution of phosphorus loading from point sources is 16% and 84% from non -point sources. Currently the proposed rules do not require any non -point source monitoring which is the segment with the largest loading at the lake. This doesn't make sense. To our knowledge after a brief informal survey, dischargers in the Neuse River Basin and the Tar Pamlico basin are not required to monitor three times a week. These basins are facing similar nutrient management concerns, but apparently heightened monitoring (three times per week) was not considered to be of sufficient benefit to make it a requirement in those permits. Another argument presented by DWQ is that the increased data collection activity would be used for special studies and additional modeling. The DWQ monitoring group has stated that they do not have the resources to perform additional modeling in the Jordan Lake Watershed. Therefore without plans to use this data for modeling there is little reason to collect the data for archival purposes. The municipalities in the Haw River Watershed are funding stream monitoring on the tributaries draining into the Haw River Arm of Jordan Lake. This monitoring is twice per month for some parameters, once per month for some additional parameters, and quarterly for some metals of interest. The DWQ is proposing to monitor the Jordan Lake water quality 12 times per year (monthly) during their 2 intensive sampling years, 6 times per year during the 1 less intensive year, and no sampling at all for 2 of the next 5 years. With those sampling frequencies, requiring the NPDES discharge permit holders to sample 3 times per week for nitrogen and phosphorus does not make sense. This does not add any resolution to the potential models or to our understanding of the lake, especially if there is no lake monitoring in progress. The DWQ modeling group suggested that the additional sampling would allow a better determination of compliance by having more data points. This is not a good argument, or else the same would hold true for the Neuse and Tar Pamlico basins. The method for determination of compliance is defined by the State, and should be uniformly applied. Our existing permit requires monitoring nitrite — nitrate and TKN monthly, and the phosphorus monitoring is required weekly. It would be logical to require weekly monitoring for both nitrogen and phosphorus at the wastewater treatment plants. This would create a more robust database than is currently available. The City of Burlington would support a requirement for weekly monitoring for the nitrogen and phosphorus concentrations in the effluent and monthly and annual loading compliance determinations.

In footnote 2, "total suspended residue should be expressed as "total suspended solids" to match the parameter name in the table above. 2. The fact sheet cites the existing TMDL for turbidity and fecal coliform for this facility. The TMDL and fact sheet indicate that further reductions in both point and nonpoint sources are needed and that further analysis to implement those reductions is required. Pls describe how you envision the "further analysis" to be conducted and when it would be conducted. One table in the TMDL did indicate to me that point source TSS limits should be less than 31 mg/l. This permit retains the fecal and TSS limits that were in the previous permit, so no reduction is being required at this time. I am concerned that since the TMDL does require point source reductions, the draft permit may not be consistent with that requirement. 1 of 1 9/13/2006 2:08 PM Public Notice AFFIDAVIT OF INSERTION OF ADVERTISMEN'I Service9-1617 ; Raleigh,.

The plant was originally constructed in 1961 as a 6 MGD trickling filter plant. In 1993 the treatment plant was upgraded to include chemical and biological phosphorous removal. The plant is situated on Quarry Rd. and is off NC Highway 70 near the town of Haw River. The treated effluent is discharged into the Haw River. Section II — Treatment Process & Operation Treatment Process Summary: The basic treatment process consists of the following elements and is explained in more detail later in this section. 1. Pretreatment — including coarse manual bar screen, grit removal, mechanical bar screen, and flow metering and recording 2. Raw waste water pumping, in -line flow equalization and equalized flow pumping 3. Chemical feed system that includes aluminum sulfate and sodium hydroxide (caustic) 4. Primary clarification 5. Activated sludge / Activated Carbon aeration (often referred to as the "P.A.C.T process" for Powdered Activated Carbon Treatment) including carbon makeup, polymer addition, secondary clarification, and sludge recycling 6. Biological Nutrient Removal (BNR) — including denitrification of the return sludge and anaerobic phosphorus release 7. Tertiary filtration — including backwash storage and pumping 8. Chlorination & dechlorination, cascade -type post aeration, and non -potable water reuse 9. Primary sludge handling and disposal — including gravity thickening; aerobic digestion, lime stabilization; and land application 10. Secondary/Carbon sludge handling and carbon regeneration — including carbon sludge thickening; high pressure wet air oxidation for sludge destruction and activated carbon regeneration, and odor control. 2004 EB Waste Operations NPDES.doc page 3 of 19 Raw sewage first passes through a grit and screening removal chamber. These facilities are designed to remove coarse settleable solids, such as rags, paper and sand from the waste stream. This process is the first step in wastewater treatment and helps protect pumps and other equipment. The raw wastewater (influent flow) is pumped to an equalization basin, although a bypass to the primary clarifiers has been provided for flexibility. The equalization basin flow is mixed and aerated by 5 floating mechanical aerators. Subsequent flow to the plant is controlled by a series of fixed -flow pumps. This smoothing of the hydraulic load greatly enhances plant performance and reliability. After the equalization basin, the wastewater flows to the primary clarifiers is where settleable solids are removed. At this stage, the settleable solids, called primary sludge, is withdrawn and thickened in gravity thickeners. The thickened sludge is then pumped to the aerobic digester (mechanically aerated) that was converted from an anaerobic digester. The sludge is stored there until it is lime -stabilized to meet 40CFR503C regulations. Finally, the lime -stabilized sludge is applied to State -permitted farmland under an approved Land Application program. The primary clarifier effluent flows to anoxic/anaerobic tanks for phosphorus release after which it is treated in two aeration basins. An alternate flow scheme puts the primary clarifier effluent directly into the aeration basins. These basins contain activated sludge and carbon. The sludge floc characteristics under these conditions provide both carbonaceous BOD removal and nitrification of ammonia nitrogen in the same tank. Powdered Activated Carbon (PAC), is an aid to wastewater treatment, has been developed by both the system suppliers and the PAC suppliers and can be applied as needed. Next, the activated sludge/carbon is settled out in four final clarifiers. A portion of the settled sludge/carbon is recirculated to the anoxic/anaerobic tanks or the aeration basins via an intermediate pump station. The remaining portion of the activated sludge/carbon is wasted (pumped) to the secondary sludge thickeners. Polymer can be added to the aeration tank effluent to aid solids settling in the secondary clarifiers. Alum can be added to the secondary clarifier effluent as the primary means of chemical phosphorous removal. Excess sludge from the activated sludge/carbon system is wasted to two gravity sludge thickeners. Then the thickened sludge/carbon slurry is treated under high pressure (700 psig) and temperature (460' F) to completely oxidize the sludge to an inert ash and at the same time, regenerate the active pores in the carbon. The ash is dewatered in a plate frame press and disposed of at the landfill as cover material. Since the PAC regeneration step destroys a percentage of the PAC, virgin PAC must be added to the regenerated PAC in order to maintain proper levels of carbon in the activated sludge (1200 — 2500 mg/L). PAC (in slurry form) is introduced into the primary effluent flowing to the aeration basins. The secondary effluent then flows through six deep -bed Dynasand upflow filter cells. Each cell contains seven filter modules. The filters function to recapture activated carbon and remove additional suspended solids and BOD. The filter backwash wastewater can be stored in a mechanically mixed storage basin and pumped back to the aeration tanks for subsequent treatment although generally the filter backwash water goes back to the plant influent. Alternately, the filter wash water is returned to the main plant flow at the plant flow at the plant headworks. 2004 EB Waste Operations NPDES.doc page 4 of 19 Disinfection of the East Burlington treatment plant effluent is accomplished through chlorination. Two solution feed, vacuum type chlorinators are used to supply chlorine solution to the chlorine contact chamber. The chorine contact chamber is also the reservoir for the treatment plant's non -potable water. Finally, the chlorinated effluent is dechlorinated with sulfur dioxide (S02) and receives post aeration by cascading down a stair -step aerator. The final quantity of effluent is measured by an open channel Parshall flume. Nine (9) industries discharging to sewers leading to the East Burlington Wastewater Treatment Plant are considered significant industrial users (SILT), and come under the City's pretreatment program. The annual monitoring data is included in the Pretreatment Annual Report prepared for 2004. Some information about these industries is included at the end of this report. A special thanks is extended to all the people who have made the operation of the East Burlington Wastewater Treatment Facility successful this past year. These individuals cannot be thanked enough for their dedicated efforts to ensure that the facility is staffed continuously, operated effectively and maintained properly. NOTE: The East Burlington WWTP has two stationary emergency generators on site. One is located at the raw sewage pump station and provides power to the raw sewage pumps. The other is located at the Zimpro soli. solids handling building and provides power to various points in the plant. In addition, the flow equalization basin pump station and the p plantopperations building have "quick connect" gear installed to connect to a portable (trailor mounted) generator. 2004 EB Waste Operations NPDES.doc page 5 of 19 Design Criteria: Average Flow to headworks and equalization basin 12 MGD Peak Flow to headworks and equalization basin 18 MGD Flow to Plant 12 MGD Population served in 2004 30,000 Biochemical Oxygen Demand (BOD) 300 mg/L Total Suspended Solids (TSS) 150 mg/L NH3-N (Ammonia Nitrogen) 20 mg/L pH 6-9 Temperature 70 —120o F Receiving Stream Haw River Process Arrangement 1.

Both of these methods satisfy the requirements of 40 CFR 503 regulations and state regulations for the disposal of wastewater residuals. The East Burlington WWTP generates approximately 5.4 million gallons (2004) of Class B lime stabilized biosolids annually for land application under non -discharge permit number WQ0000520 issued by NCDENR to the City of Burlington NC. This product is a mixture of hydrated lime and biosolids using primary sludge. This mixture averaged 3.6% solids during 2004. The lime stabilization method involves the aerated storage (approximately 400,000 gallons of storage capacity) of gravity thickened primary sludge. As space becomes available, this thickened sludge is transferred to lime stabilization contact tanks for stabilization with hydrated lime to pH >12 for over 2 hours and pH >11.5 for the remainder of the 24 hour process. This sludge is then stored (approximately 800,000 gallons of storage capacity) and maintained at pH 11.5 or higher until it can be applied to permitted farmland. Application as a liquid sludge is by surface spray or subsurface injection. The City has over 3000 acres permitted by the NCDENR for the sludge management program. The City contracts with a biosolids management company (Synagro) to perform the transportation and site application of the biosolids product. Synagro also assists with the program recordkeeping and reporting. Annual reports are submitted to the USEPA and to NCDENR. Secondary sludge is thickened in gravity thickeners and processed through a Zimpro® wet air oxidation unit at high pressure (840 psi) and temperature (4600F). The liquid waste stream is processed to capture regenerated powdered carbon and return it to the activated sludge process train. The "ash" or waste solids from the process are settled in a clarifier and dewatered with a plate -frame press to about 65% solids. These residuals are hauled to the Alamance County landfill or other lined landfills and incorporated as cover material. Approximately 10.5 million gallons (2004) per year are processed through the Zimpro® process. The solids content of the sludge stream feeding the Zimpro unit averaged 3.7%. TCLP testing of the land application biosolids and the Zimpro "ash" taken to the landfill has been provided to the State in the annual reports. The 2005 data is attached to this NPDES permit application.

Turbidity also exceeded the water quality standard in 10 percent of samples at site BA761. This segment is Not Rated for recreation because fecal coliform bacteria screening criteria were exceeded at site BA761. The Brush Creek watershed drains large impervious areas from the Piedmont Triad International Airport as well as residential areas west of the airport. Road construction along the I-85 corridor has also impacted water quality in Brush Creek. DWQ staff noted several storm sewers draining directly into the creek and evidence of very high storm flows. There is no riparian area on Brush Creek as it flows through a golf course. A stressor survey conducted in 2003 found habitat degradation caused by modified watershed hydrology resulting in streambank erosion and sedimentation continues to stress the benthic community in Brush Creek. 2005 Recommendations DWQ will continue to monitor water quality in the Brush Creek watershed. DWQ recommends that the City of Greensboro (Appendix V) continue to monitor water quality at site BA761 and submit these data to DWQ. Construction of the FEDEX project should use and maintain BMPs to minimize further disturbance to the Brush Creek watershed. DWQ will determine if intensive sampling is needed to assess the fecal coliform bacteria standard in this creek (Appendix X). Further recommendations to protect streams in urbanizing areas and to restore streams in existing urban areas are discussed in Chapter 31. Segments 16-11-4-(1)al and a3 will remain on the 303(d) list of Impaired waters. Segment 16- 11-4-(1)a2 will be removed from the 303(d) list because of the Good fish community rating. TMDLs (Chapter 35) will be developed for identified stressors within 8-13 years of listing. 2.3.2 Haw River [AU# 16-(1)d2, d3 and et 2000 Recommendations The 2000 basin plan recommended that a TMDL be developed for turbidity and fecal coliform bacteria in this segment of the Haw River. The plan also noted that improvements to the Buffalo/Reedy Fork watersheds were also needed. Current Status The Haw River [16-(1)d2] from the subbasin boundary to Service Creek (10.1 miles) is Supporting aquatic life because no criteria were exceeded at sites BA59 and BA746, although turbidity exceeded the standard in 9.8 percent of samples collected at site BA59. The fecal coliform bacteria screening criteria were exceeded during the assessment period, but bacteria levels were below the standard during resamples the following summer at sites BA59 and BA746. This segment is Supporting recreation. The Haw River [16-(1)d3] from Service Creek to NC 49 (2.1 miles) is Impaired for recreation because the fecal coliform bacteria standard was violated at site BA74. Although this segment is Supporting aquatic life, the turbidity standard was exceeded in 10 percent of samples collected at site BA74. Turbidity violated the standard in two storm events monitored by DWQ. Chapter 2 — Cape Fear River Subbasin 03-06-02 21 Waters in the following sections are identified by assessment unit number (AU#). This number is used to track defined segments in the water quality assessment database, 303(d) Impaired waters list and the various tables in this basin plan. The assessment unit number is a subset of the DWQ index number (classification identification number). A letter attached to the end of the AU# indicates that the assessment is smaller than the DWQ index segment. No letter indicates that the assessment unit and the DWQ index segment are the same. 2.2 Use Support Assessment Summary Use support ratings were assigned for waters in subbasin 03-06-02 in the aquatic life, recreation, fish consumption and water supply categories. All waters are Impaired on an evaluated basis in the fish consumption category because of fish consumption advice that applies to the entire basin. In the water supply category, all WS classified waters (4,201.1 acres and 182.3 miles) are Supporting on an evaluated basis based on reports from DEH regional water treatment plant consultants. Refer to Appendix X for a complete list of monitored waters and more information on Supporting monitored waters. There were 179.8 stream miles (45.7 percent) and 3,811.2 freshwater acres (88.4 percent) monitored during this assessment period in the aquatic life category. There were 63.5 miles (16.2 percent) of Impaired waters in this category. There were also 16.5 stream miles (4.2 percent) Impaired for recreation in this subbasin. 2.3 Status and Recommendations of Previously and Newly Impaired Waters The following waters were either identified as Impaired in the previous basin plan (2000) or are newly Impaired based on recent data. If previously identified as Impaired, the water will either remain on the state's 303(d) list or will be delisted based on recent data showing water quality improvements. If the water is newly Impaired, it will likely be placed on the 2006 303(d) list. The current status and recommendations for addressing these waters are presented below, and each is identified by an assessment unit number (AU#). Refer to the overview for more _ information on AUs. Information regarding 303(d) listing and reporting methodology is presented in Appendix VII. 2.3.1 Brush Creek [AU# 16-11-4-(1)al, a2 and a3] 2000 Recommendations .The 2000 basin plan recommended that Brush Creek be resampled and that DWQ work with the City of Greensboro to improve water quality where possible. Current Status Brush Creek [16-11-4-(1)al] from source to SR 2085 (2.4 miles) is Not Rated for aquatic life because a benthic community rating could not be assigned at site BB93 because of the small size of the stream. Brush Creek [16-11-4-(1)a2] from SR 2085 to 0.3 miles downstream of SR 3820 (1.8 miles) is Supporting aquatic life because of a Good fish community rating at site BF69.

The Haw River [16-(1)e] from NC 49 to Cane Creek (18.5 miles) is Supporting aquatic life because of a Good -Fair benthic community rating at site BB220; however, the turbidity standard was exceeded in 7 and 10 percent of samples collected at site BA76 and BA90. This segment is Not Rated for recreation because the fecal coliform bacteria screening criteria were exceeded at sites BA76, BA90 and BA 118. 2005 Recommendations DWQ will work with nonpoint source agencies and local governments to identify funding sources and BMP opportunities to implement reductions in TSS and fecal coliform bacteria as recommended in the TMDL. DWQ will continue to monitor the Haw River. Segment 16-(1)d2 will be removed from the 303(d) list of Impaired waters because the fecal coliform bacteria and turbidity standards were not violated. Segment 16-(1)d3 will remain on the 303(d) until water quality standards for fecal coliform bacteria are met, although turbidity will be removed as a cause of impairment based on data from site BA74. TMDLs (Chapter 35) will be developed for identified stressors within 8-13 years of listing. Water Quality Initiatives The Ag Sediment initiative estimates that $650,000 is needed to install field agriculture BMPs and livestock exclusion to reduce agriculture loading of turbidity and fecal coliform bacteria to this segment of the Haw River. The survey also noted urban development, impervious surfaces, and streambank erosion in addition to agriculture as sources of sediment. In 1999, Graham received a $20,000 CWMTF (Chapter 34) grant to study the feasibility of a greenway between I-85 and NC 54 along the Haw River [16-(1)e]. In 2001, Graham received a $140,000 CWMTF grant to purchase 22 acres along the Haw River as part of the greenway system. In 2001, Piedmont Triad COG (Chapter 34) received a $65,000 CWMTF grant to develop a riparian corridor plan targeting 214 parcels along the Haw River. 2.3.3 Horsepen Creek [AU# 16-11-5-(0.5)a and b and 16-11-5-(2)] and Unnamed Tributary at Guilford College [AU#16-11-5-1-(2)] 2000 Recommendations The 2000 basinwide plan recommended that Horsepen Creek be resampled and that DWQ work with the City of Greensboro to improve water quality where possible. DWQ, with the CWMTF, conducted a detailed study of the watershed as part of WARP project to identify stressors and recommend solutions to water quality problems. Current Status Horsepen Creek [16-11-5-(0.5)a] from source to Ballinger Road (1.8 miles) is Not Rated for aquatic life because benthic community ratings could not be assigned at sites BB369 and BB205.
