Please review this memo and share your thoughts with me prior to a meeting we are trying to set up with the Section Chief to obtain his guidance. Steve Tedder has indicated his willingness to support Color permit limits. I have asked Steve for the opportunity to receive your input prior to our discussions with Chuck. We will attempt to set up a meeting late next week. North Carolina Division of Environmental Management Water Quality Section / Technical Services Branch Intensive Survey Unit 1 9/30/88 Nov � 0 Memorandum To: Charles Wakild 4 From: Jay Sauber Thru: Steve Tedder Subject: Color Problems in the Dan River On July 26th, 1988 the Executive Director of the Virginia State Water Control Board transmitted a letter to R. Paul Wilms. This letter indicated that higher than normal color levels in the Dan River were affecting industrial and potable water supplies. The following information should be beneficial in formatting our response to Virginia. Region IV and Region III of EPA have also equested that North Carolina send a response. to tharn as soon as possible. Attachments: July 26, 1988 Letter from Richard Burton Executive Director Virginia Water Control Board to Mr Alvin Morris Director Water Management Division EPA Region Ill. " Recent data indicate that two POTW's in the City of Eden, North Carolina have color in their effluents well above Virginia's allowable limit." Letter requests assistance to protect beneficial uses of waters. July 26, 1988 Letter from Richard Burton to Paul Wilms indicating color problems coming from Dry Creek and Mebane Bridge Facilities in Eden. Letter requests DEM to eliminate or reduce the threat to water supplies and industrial users. August 18,1988 Letter from Paul Wilms to Richard Burton indicating DEM will investigate and study the situation. When these letters were referred to the Intensive Survey Unit for investigation (about the end of August) we began to make numerous inquiries to gather available pertinent information. On September 1,1988, Dennis Asbury, Director of Public Utilities for the Town of Eden (G19/627-1009), indicated that Pannil Industries, a textile operation, expanded its Martinsville, Va. operation to Eden, NC in January of 1987. Pluma Industries (a spin-off linked to Pannil) also expanded from Martinsville shortly after Pannil. Mr. Asbury indicated that in 4 sampling runs ADMI values UPS of Mebane Bridge Eff ranged from 11-46. Effluent Values from Mebane Bridge ranged from 300-400 ADMI. Downstream values ranged from 17-40 ADMI. Values at the Eden Dry Creek WWTP ranged from 520-1200 ADMI. Downstream values below the Dry Creek M facility ranged from 11-46 ADMI. Mr. Ashbury has sent us the results of his sampling efforts. Mr. Asbury also indicated that the cities of Danville and South Boston had made some color complaints. Attachments: Dan River Schmatic September 6, 1988 Letter from Dennis Asbury to Kurt Trumbower transmitting ADMI data collected by Eden. Letter indicated ADMI has increased in Eden's discharges over the last two years. Mr. Herbert Dawson from the City of Danville Water Treatment Plant (804/799-6473) was contacted. Mr Dawson indicated that they are not sampling for ADMI but are performing conductivity measurements. They use conductivity analyses to determine when they should add additional treatment chemicals for color removal. He said that he thought the color problem was related to Philpott Reservoir releases. Danville's water intake is located upstream of the Robertson Bridge Powerplant Gam.. Mr. Dawson indicated that the color situation Uegan several years ago. He will check his records for documentation and further clarification. Mr Dawson indicated that the color problem at Danville varies with the river flow. Low flow situations with low turbidity are worst case conditions. With low flows additional flocculant is added on a regular basis (weekly). The drought conditions of this year were a particular problem. Mr Dawson indicated that they have not had to shut down water production. They have had to increase their dosage of flocculant (Alum) to remove color. This increase in dosage has gone from one grain, on the average, to 1 1/2 grains, on the average, to remove color. They have not used polymer on a regular basis but will try some experimentation in the future. When they monitor conductivity as an indicator, usually the river conductivity runs about <100 umhos. When an event causes the need for additional flocculation, conductivity values get higher (300 -500 umhos). Mr Dawson indicated that he had been working with Mr Mitch Childrey of the'Virginia Health Dept. on this issue. He indicated that Mr. Childrey's data did not correlate color with conductivity on a routine basis. He will check his records and send us pertinent data. As of this time no data has been received. Mr.Gray Hauser, DEM regional office in Winston Salem,NC was contacted for his knowledge of the situation. Gray believes that both Pannil and Pluma discharge to a pump station and the first 1/2 MGD goes to the Dry Creek WWTP while the remainder goes to the Mebane Bridge WWTP. Attachment: September 6,1988 Memo from Gray Hauser with attached inspection data from Eden facilities. We then contacted Mr.Mark Wilkerson, Chief Operator of the South Boston Water Treatment Plant. (804/572-4438). Mr. Wilkerson indicated that color episodes in the Dan River can be removed by treatment but the cost of treatment doubles due to the necessity of having to add additional Chlorine and Alum. The resultant mixture turns their sand filters dark (black) with the adsorbed dye waste. They determine the need for adding additional chemicals by monitoring conductivity in the raw water (normally <120 — prob-lem levels >300) and by telephone warnings from the Danville Water Treatment Plant in Virginia. Mr Wilkerson indicated that the color situation has been occurring for several years. A telephone conversation with Mr Lester Neal Superintendent of South Boston WTP indicated that the problems with color go back beyond January 1987. In fact Mr Neal had letters that indicated EPA Region III and the local health department said the problem was from the Smith River back in April of 1986, and in December of 1987. Mr Neal is putting his documents together to share with us if we make any on site visits. On September 23,19881 had a telephone conversation with Mr. Bob Burnley head of the Roanoke Regional office of the Virginia Water Control Board. Mr Burnley was very cooperative as usual and we discussed the Dan River color situation as well as the Smith River color situation. Mr t Burnley was asked to review the current status of the Smith River color situation in regards to the permit limits of the Martinsville WWTP, the Upper Smith River WWTP and the Lower Smith River WWTP, Mr Burnley indicated that Martinsville had reviewed many options for color removal at the WWTP and at pre-treatment facilities. The color removal option of pre-treatment was not viable because the indirect dischargers did not want to get into the color removal business. Flocculation was not considered because of the cost of treatment and the difficulties of handling the sludge - which may be considered toxic. Activated carbon was not viable due to space constraints for carbon regeneration and sludge problems. Chlorine oxidation was not considered viable due to the extremely elevated levels of chlorine necessary to oxidize the color with concerns over toxic residuals. The Martinsville WWTP appears to be settling on an Ozone oxidation method. This method is the most expensive - costing approximately $5 million in capital expenses with $15-20 thousand in monthly operating and maintenance - most of which are power requirements for Ozone generation. Mr Burnley was of the opinion that the Martinsville WWTP would be in compliance with their effluent color limits in about one year. The Upper Smith River WWTP is currently underloaded and is not experiencing color treatment problems with biological removal. The Lower Smith River WWTP is not planning to add any special color removal treatment trains to its system. I questioned the wisdom of this decision since 4 MGD of the Martinsville influent are scheduled to be sent to the Lower Smith WWTP. Mr Burnley indicated that he too had questioned this decision. But was told by the Lower Smith River WWTP that, they felt it was not necessary. Mr Burnley was asked about the letters from Mr. Richard Burton - indicating concern over the Eden WWTP's discharging elevated color levels. Mr Burnley indicated that since Virginia had constructed permits to protect the water supply uses of the Si pith River that he felt that North .Carolina shculd G:;t in a similar fashion to prc:ect the uses of the 'Dan River. It was indicated to Mr . Burnley thai we shared his concerns and were in t; ,e process of our analysis of the situation. Mr Burnley was informed of our concerns of the Smith River being a contributing source to Dan River problems. He indicated that that might be the case. We requested information on Virginia dischargers in the Dan River between the Smith River confluence and South Boston in order to construct a mass balance equation to evaluate the importance of the Smith River color and the two Eden facilities on the color problems experienced on the Dan River. Mr Burnley indicated that he would make this information available. We have not yet received any additional information from Virginia. In order to evaluate the contribution of the Eden WWTP's colored effluent on the Dan River we have used a mass balance approach - the same approach Virginia used in setting color limits for the Martinsville, Upper Smith, and Lower Smith WWTP's.

This target concentration and a mass balance equation were the basis of the Virginia permit limits applied to the Martinsville, Lower Smith and Upper Smith WWTP's. Virginia, like North Carolina, does not have a numerical color standard for the protection of water supplies. The target level of 24 ADMI units was agreed to by all agencies because it was similar to the recommendations of the Virginia State Health Department of a limit of 15 Pt Co units and, more importantly, the 24 ADMI units corresponded with documented data on the level of color that could be treated by the Fieldcrest Mills WTP to produce a final product free of color. We have been monitoring ADMI color in the Smith River on a monthly frequency since December of 1986 as part of our Ambient Monitoring System (AMS). Our past investigations with the state of Virginia and Fieldcrest Mills indicated color problems in the Smith River on a regular frequency - usually during the first part of each week. While our ambient monitoring of the Smith River is not scheduled to detect these color slugs it is apparent from the following data that color levels in the Smith River still far exceed the target level of 24 ADMI units.

If color levels from the Smith River were equal to 24 ADMI color units and the Eden Mebane Bridge WWTP was discharging a concentration of 248 ADMI and the Eden Dry Creek WWTP was discharging a concentration of 542 ADMI color units and Miller Brewing was at 5 ADMI and Fieldcrest was at 24 ADMI the we would not predict a violation of the 24 ADMI "standard" at the water intake for the city of Danville, Virginia. In fact we would predict a level of 17 ADMI units. This scenario represents the average effluent concentrations of color_ from the Eden facilities. In order to evaluate the maximum potential of creating a problem for Danville from the Eden WWTP facilities the following scenario is presented. If color levels from the dischargers to the Smith River were in compliance with the Virginia NPDES permit limits resulting in 24 ADMI color units in the Smith River and the Eden Mebane Bridge WWTP was discharging a concentration of 640 ADMI and the Eden Dry Creek WWTP was discharging a concentration of 1234 ADMI color units and Miller Bitawing was at 5 ADMI and Fieldcrest was at 24 ADMI the w,� would p►edi�, violation of the 24 ADMI "standard" at the water intake for the city of Danville, Virginia. However, we would predict a level of only 29 ADMI units. In order for this situation to occur both the Meban Bridge and the Dry creek facilities would have to have maximum concentrations during a 7Q10 event with no instream settling of color. Other alternative scenarios are attached for further examples. Waste water treatment facilities in Eden have contributed to the concentration of ADMI color in the Dan River. Furthermore, the Eden Dry Creek WWTP and the Mebane Bridge WWTP have increased the concentration of ADMI color in their effluents in recent years. However, based on this analysis and based on conversations with various treatment facility operators, it is highly unlikely that the Eden facilities are solely responsible for the problems encountered by the Cities of Danville and South Boston. 10 IL Additional conversations with Dennis Asbury have indicated to me that the City of Eden is well aware of their potential problems managing highly colored effluents. As recently as last Tuesday, the City of Eden's consultant on their Master Plan recommended abandoning the Dry Creek facility. Pluma and Pannil industries are acutely aware of their situation and have had some brief discussions with the City of Eden related to the likely future need of pre-treatment for color. Pannil and Pluma have a great deal of color experience - developed as a result of their difficulties in Martinsville, Virginia. It may be inevitable that the City of Eden will "kick, scream and holler" if we attempt to include a color limit in their NPDES permits. However, if DEM could move forward with the inclusion of color limits in Eden's permits to protect the water supplies of Danville and South Boston many benefits could possible accrue. -If color limits are based on monthly averages, Eden would likely have no present difficulty with compliance. .We would be clearly indicating to Virginia our concern for the protection of water supplies. -We would give Eden some additional leverage to collect color specific sewer user charges. -We would give Eden some additional leverage to implement color pre-treatment requirements. -We would protect the downstream water supplies from further increases of color due to any future textile expansions. Obviously our position could be bolstered with some additional review of this information and with some additional data. Data gaps do exist. No color information is available on Miller Brewing, Fieldcrest Mills, Duke Power, tributary streams, and any Virginia dischargers located downstream of Eden. We welcome your questions and would be glad to provide additional information. 0 Richard N. Burton executive Director Post Office Box 11143 Richmond.

Hollimon, Jr. David H. Miller Ronald M. Plotkin Velma M. Smith Patrick L. Standing W. Bidgood Wall, Jr. Robert C. Wininger For the past few months, the staff of our Roanoke office has been receiving an increased number of complaints from the Danville area regarding higher than normal levels of color in the Dan River. This high level of color is affecting industrial and Dot -able water supplies. The source of the color appears to be tbn discharges from the City of Edenis Mebane Bridge .and Dry Creek wastewater treatment plants. These facilities are apparently unable to remove the color being generated by a new textile plant in Eden. Dischargers in Virginia which may affect the potable water supplies in North Carolina have color and other nonconventional pollutants limited by NPDES permits. The color limits are very low. The color currently being discharged from the Eden plants is two to three times the 200 ADMI color units being required in Virginia. The purpose of this letter is to request that your agency take the necessary steps to eliminate or reduce this threat to potable and industrial water supplies in Virginia. The West' Central Regional Office in Roanoke can provide more 'details if necessary. Thank you for your attention to this important water quality issue.

I Y Dear Al ' SECTION Two years ago the states of Virginia and North Carolina, with assistance from EPA Regions III and IV, cooperated on an ...n.tensive water quality study on the Smith Ra.ver. The purpose of that study was to determine the -acceptable level of color from textile wastes in surface water used as potable and industrial water supplies. The outcome of that cooperative effort was the establishment of effluent limits for color in the VPDES permits of three POTWs on the smith River in Virginia. Your assistance, and the assistance of the staffs of both EPA regional offices was invaluable in the successful resolution of that color problem. Ism writing you today to bring to your attention another situation involving color in that same area. When strict color limits were established for the dischargers in Virginia, they were established with the agreement that the State of North Carolina would also limit color -discharges from sources which affect waters flowing into Virginia. Recent data indicate that two POTWs in the City of Eden, North Carolina have color in their effluents well above Virginia's allowable limit. .� 4 1 Mr. Alvin R. Morris Page Two I'm requesting your assistance and the assistance of Region IV in assuring that color being discharged by treatment facilities in North Carolina is limited to those levels which will protect the beneficial uses of Virginia municipalities and industries.

C. Division of Environmental Management P. 0. Box 27687 Raleigh, NC 27611 Dear Mr. Trumbower: SUBJECT: DAN RIVER COLOR COMPLAINTS Attached are the ADMI (American Dye Manufacturers Institute) color analyses results you requested. i understand that the State of Virginia has complained that Eden's wastewater discharges have three to four times the color level allowed at the Martinsville, Virginia Wastewater Treatment Plant, and that color in the Dan River downstream of Eden has interfered with potable water treatment and industrial processes. As the attached analyses show color levels in Eden's discharges have increased over the last two years. However, the analyses also show that the color in Eden's discharge had no significant impact on color in the Dan River downstream of Eden for the flow conditions existent at the time of sample collection. Some differences exist between Eden's discharges into the Dan River and Martinsville's discharge into the Smith River. The dilution ratio of the Smith River at Eden at 7Q10 (regulated) to the Martinsville Wastewater Treatment Plant effluent is less than 20:1. The dilution ratio of the Dan River below the confluence at 7Q10 to Eden's Wastewater Treatment Plant effluents is greater than 40:1. The problems created by the Martinsville discharge at the Fieldcrest Cannon Central Filter Plant in Eden occurred on a regular basis and t 2 were extensively documented over a period of thirty years. Before action is taken toward imposing color limits on Eden's discharges I hope similar documentation will be developed, specific to Eden's discharges and their effects on the Dan River and downstream users. If you have any questions about the attached data, please call me at 919-627-1009.
