Easley, Governor State of North Carolina William G. Ross, Jr., Secretary Department of Environment and Natural Resources Alan W. Klimek, P.E., Director Division of Water Quality Subject: Issuance of Major Modification NPDES Permit NC0025071 Mebane Bridge WWI? Rockingham County Dear Mr. Asbury: Division of Water Quality (Division) personnel have reviewed and approved your request for a major modification of the subject permit. Accordingly, we are forwarding the modified pages of the NPDES discharge permit. 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 May 9, 1994 (or as subsequently amended). The following modifications have been made to this NPDES permit and are effective beginning August 1, 2005: • An additional effluent sheet with a permitted flow of 10.0 MGD and a color limit of 405 ADMI has been added to this permit. In comparison, the facility's current permit contains an effluent sheet for 13.5 MGD flow and a color limit of 300 ADMI. The request for this interim flow of 10 MGD is based on the loss of industrial flow to the city, and the proposed color limit of 405 ADMI provides some buffer for the textile facilities. The color limit is based on maintaining the same color "mass" (i.e., 13.5 MGD x 300 ADMI = 4,050 color units = 10.0 MGD x 405 ADMI). This color mass balance approach is consistent with the methodology used to develop previous color limits for this facility, and is based on the DWQ 1990 report "An Update of Color Control Activities in the Smith and Dan River Basins." No other parameters have been modified under this permit modification. • Both Effluent Sheets have been reworded to allow the facility to revert back to the 13.5 MGD Effluent Sheet with a letter request, should the facility add more industrial flow in the future, or based on the facility reaching 90% of permitted flow. • Addition of Special Condition A (4)- Color Condition, which requires the permittee to initiate additional color removal (back to the previous color limit of 300 ADMI, if needed) should the City of Danville encounter color problems at their water treatment plant due to Eden's wastewater discharge.

The facility serves the City of Eden (pop. 14,000), the town of Wentworth (pop. 2700) and three Significant Industrial Users (SIUs). These SILTS are textile plants — National Textiles, LLC, Santee Company, LLC, and Karastan Rug Mill — and are regulated through the City's pretreatment program. Due to the loss of industrial flow, the permittee has requested an interim reduction in permitted flow down to 10.0 MGD, combined with an increase in the color limit to 405 ADMI, which will provide some additional buffer for the textile facilities. The requested increase in the color limit would result in no net increase in color "mass", which would be maintained at 4,050 color units (i.e., 300 ADMI at 13.5 MGD = 4,050 color units = 405 ADMI at 10.0 MGD). This mass balance approach is consistent with a 1990 color mass balance model that was used to generate previous color limits for 7.0 MGD (540 ADNM, 9.0 MGD (430 ADMI), and 13.5 MGD (300 ADMI). Color limits were initially imposed to protect for the City of Danville's water supply intake located approximately 22 miles downstream in Virginia. Since that time, several textile facilities discharging to this system have closed. The Eden facility has maintained compliance with the current color limit, and the discharge has shown no color impact at the downstream station located approximately 4 miles below the discharge. Since the same color "mass" will be maintained, and since there is significant dilution and several color dischargers have left, no color impact is anticipated due to this proposal. However, the proposed permit modification includes a new Special Condition A.(4), which would require the facility to reduce color back to previous levels (as needed), should the City of Fact Sheet NPDES NC0025071 Modification Paor I Danville experience color problems arising from this proposal. No other parameters will be affected by this proposed modification. The Eden facility will revert back to its current 13.5 MGD, Effluent Sheet upon reaching 90% of the permitted interim flow (i.e., 0.9 x 10.0 MGD = 9.0 MGD) based on 12-month average flow, or by a letter request for such change based on new industrial flow commitments.

Upon review, it was noted that concerns associated with Virginia State Waters, principally the Town of Danville - Public Water Supply Intake, have been adequately addressed in the proposed permit modification. Additionally, sufficient permit safeguards appear to be in place to address future growth. Specifically, DEQ concurs with the "mass" based approach utilized for the subject facility's color limitation. This approach results in a color limitation of 405 ADMI at 10 MGD. The proposed permit also contains provisions for a color limitation of 300 ADMI at 13.5 MGD. Lastly, the proposed permit contains a special condition, A.(4) Color Condition, that requires the treatment plant to initiate additional color removal to acceptable levels (back to the previous color limit of 300 ADMI, if needed) if any color problems are encountered at the City of Danville Water Treatment Plant located 22 miles downstream.

If the permitted flow is reduced to 10.0 MGD then they would be at about 75% of the permitted 10.0 MGD flow requested. They will need to be aware of the 80% rule but this would not really come into play until March of 2006. Steve On 5/23/2005 12:23 PM, Tom Belnick wrote: Hi Steve- The City of Eden has requested an NPDES permit mod. They currently have a flow limit of 13.5 MGD and a color limit of 300 ADMI. They are requesting an interim phased flow of 10 MGD and a color limit of 405 ADMI (all other parameters remain the same), which maintains the same color "mass" (flow x ADMI= 4,050 color units). There is a color model developed in 1990 which used this mass balance approach to develop color limits at several flows (7, 9, 13.5 MGD). It sounds like Eden is seeking some relief for their textile discharger. Instream data does not show any color problem at the downstream station, and they have been discussing the idea with Virginia (Danville and VaDEQ). I don't have a problem with their request. Let me know if WSRO is ok with this.

Va. 24541 Tel (434) 788-W:t Fax (434) 799-%W have received your letter dated February 9, 2005 requesting support for the City of Eden's efforts to have Its wastewater treatment plant discharge color limits modified from 300 ADM[ color units at a flow of 13.5 MGD to 430 ADMI color units at 9 MGD. I have reviewed the information that you submitted previously, concerning how the limits were arrived at. It Is understood that the 300 CU limit was dstablished assuming color discharges from the Martinsville/Henry County, Virginia area. Currently, there are- no discharges from the Martinsville/Henry County area with color; therefore, the limit imposed on the Eden wastewater discharge may not be appropriate, I believe the City of Danvllle can support the proposed color limit and flow change as requested provided the following issues are addressed. nal 1. Criteria are put in place in order that color limits can be equitably established �pc in the future, as needed, should other future wastewater discharges have color. These criteria should be applied In both North Carolina and Virginia in order that there be no unfair competition for solicitation of new industries or expansion of existing Industries. 2. We would request that the City of Eden provide color testing of the Dan River �A ' at Danville at no cost to the City of Danville. The City of Danville personnel would deliver samples to the Eden Wastewater Treatment plant for analysis. The frequency of the testing will have to be established and may need to be increased or decreased depending on the results of the testing. Initially, I anticipate that two samples per week should be collected and -analyzed. FAjh 3. Any problems encountered with color In the Dan River at Danville will result Ivilt In the City of Eden initiating additional color removal treatment to lower the - color In their wastewater treatment plant discharge. As discussed, the color should be removed to acceptable levels at the wastewater treatment plant, 05/19/2005 16:54 3366233933 EDEN WATER FILT PAGE 03 March 22, 2005 Page Two 3. (Con'd) not at the water treatment plant. During our previous discussions, all agreed this would be appropriate. I would suggest that a meeting be set up for all concemed parties to discuss this issue further. Particularly, of concern, is to have an agreement between the North Carolina Department of Environment and Natural Resources and the Virginia Department of Environmental Quality on how to handle or address new wastewater industrial discharges, which may have .color in It In the future.

Alt cK.. APO 1 2 2005 DENR - WATER QUALITY POINT SOURCE BRANCH Subject: NPDES Permit NC 0025071 Mebane Bridge WWTP Rockingham County On behalf of the City of Eden I hereby request that the subject permit be modified to include a set of limits on the monthly average flow rate and monthly average discharge color limit to those of the middle case in Table 3 of the Division of Water Quality's August, 1990 report, An Update of Color Control Activities in the Smith and Dan River Basins. This new combination is 9.0 MGD (million gallons per day) and 430 ADMI (American Dye Manufacturers Institute) color units. This request does not increase the Mebane Bridge WWTP's permitted total maximum discharge of color to the Dan River. To protect Eden's infrastructure investment, should a new large industry want to come to Eden, I also request the permit modification include appropriate language to facilitate a quick return to the plant's current flow and color limits by a letter request. This request is being made in an effort to better assist local industries in very competitive markets while Eden is not using a significant amount of its wastewater plant capacity. As you are aware, the color of the Dan River is of considerable interest to the City of Danville, Virginia. We have coordinated this request with Mr. Bang Dunkley, P.E., Director, Division of Water and Wastewater Treatment of the City of Danville, and the City is supportive of our request. Attached is a letter from him confirming their support and identifying sampling, analyses, and treatment adjustment issues with which we fully agree. I concur with and support Mr. Dunkley's comment that the limit imposed on Eden's wastewater discharge may not be appropriate. I will request assistance from NC DWQ in setting up a program to thoroughly review this limit. 191 Mebane Bridge Road • Eden, NC 27288-5346 • (336) 627-1009 • Fax (336) 623-3933 JJP With the assistance of Mr. Dunkley and the NC Division of Pollution Prevention and Environmental Assistance, this permit modification request has been discussed with the Virginia Department of Environmental Protection (VA DEP), Lynchburg Regional Office, which issues the permits for the City of Danville. They have also been supportive of this modification request, and would like at some point for there to be a formal exchange between NC DENR and VA DEP to reach agreement on how to handle new industrial wastewater discharges containing color into the Smith and Dan Rivers. Please advise me or Bill Albright of DPPEA on when and how you would like this to take place. Please let me know if you need any additional information, or if we can do anything to expedite this request, as our industries are under considerable pressure. Thank you for your assistance in this matter.
