Box 4000 175 Main Street 4.9 MGD Industrial, domestic, groundwater remediation, stormwater, and landfill leachate Major Modification Haywood Pigeon River C Yes. Biological impairment. 04-03-05 130 mil 52 cfs at Canton and 120 cfs at Hepco 63 cfs at Canton and 183 cfs at Hepco 89.9 cfs at Canton 325 cfs at Canton and 677 cfs at Hepco 100% (See Text Below) 2621 Asheville Canton (E7SE — State Grid) Sergei Chernikov, Ph.D. June 28, 2024 The Blue Ridge Paper was established in 1908 to produce pulp for the Champion paper mill in Hamilton, Ohio. Blue Ridge paper acquired ownership of the mill in May of 1999 from Champion International. In 2007, the facility was purchased by the Rank Group and was operating as a subsidiary of Evergreen Packaging. The company historically employed about 1,500 people in North Carolina. The facility was shut down on May 24, 2023. Currently the wastewater treatment plant primarily treats domestic wastewater from Canton (—I.1 MGD), the other miscellaneous sources include groundwater remediation, landfill leachate, and stormwater. After facility completed the cleanup of the equipment at the end of 2023, the average effluent volume was 1.88 MGD, with the highest flow of 7.98 MGD. Therefore, the permitted flow limit will be reduced to 4.9 MGD. The facility is currently in escrow and the new owner will be TBD Utilities LLCnegotiating the sale of the property to a redevelopment company. Upon completion of the sale, the new owner would have to submit the Engineering Alternative Analysis to justify the requested flow limit. The facility has been purchased by TBD Utilities LLC in 2024. In August 2024 the facility requested that groundwater remediation was explicitly added to the permit since the decision has been made to conduct groundwater remediation activities at the site and approximately 0.25 MGD will be added to treatment. The Page 1 of 5 new RPA was conducted based on the new Form 2C submitted by the permittee, this Form 2C included groundwater data. Temperature The facility first requested and received a 316 (a) variance (approved by EPA) for temperature on August 6, 1985. Since the facility no longer generates heated wastewater, the variance is no longer necessary and will be removed from the permit. Dioxins Elevated levels of dioxins were found in fish tissue in the Pigeon River (around the late 1980s). Subsequently, a fish consumption advisory was issued for sport fish, catfish, and carp. The Canton Mill has not discharged any detectable levels of 2,3,7,8-TCDD to the Pigeon River (since 1989) and dioxin in fish tissue continues to decline. Most fish consumption advisories in North Carolina and Tennessee were removed in 1998 and 2002. The last fish advisory for Common Carp in Waterville Lake was removed on January 7, 2007. There are no fish advisories in the Pigeon River at this time. The May 2010 NPDES Permit for the Blue Ridge Canton Mill required three (3) additional years of fish tissue sampling and surveillance. During the sampling years between 2008-2013 the concentrations in fish tissue fillets were below the NC DHHS 4 ppt TEQ [toxic equivalency] action level for fish consumption advisory. In 2014, TEQ values were below detection for channel catfish for both sampling Stations; however, in Common Carp, TEQ values were 9.619 ppt for Station 4A and 2.928 for Station 4B. The TEQ results for Common Carp fillets in 2014 and 2007 could be anomalies, or could indicate that some fish are present in the population with relatively higher TEQ values. EPA conducted a High Volume dioxin sampling in the Pigeon River in 2014 and concluded that "the most potent of congeners in the series, 2,3,7,8 — TCDD, was not detected in dissolved samples at the reporting limit of 0.0012 parts per quadrillion at any station". During the previous permit renewal all sampling results showed results below TEQ action level. Since the fish dioxin concentration have been reduced steadily during the last several decades, the facility had no dioxin detection in it's effluent since 1989, the production of pulp and paper has been eliminated, and based on the EPA High Volume dioxin sampling results, the fish tissue sampling requirement in the permit will be eliminated. 316(b) Since the cessation of production, the facility withdraws less than 2.0 MGD from the Pigeon River and is not subject to 316b rule. Instream Monitoring Historically, Blue Ridge Paper conducted extensive stream monitoring, including one upstream and seven downstream monitoring stations. Since the facility was shut down in 2023, this regime is no longer necessary and only one downstream monitoring station will remain in the permit to estimate impact from miscellaneous waste streams such as landfill leachate. Table 1. Instream Monitoring Requirements Stream Mile Location Description Parameter Frequency Desienation Marker Page 2 of 5 DN1 62.9 Pigeon River at Fiberville Bridge Temperature Weekly D.O. Weekly Conductivity Weekly Fecal Coliform Weekly Color Weeklv Compliance Summary During the review period (05/2019 through 05/2023) the following NOVs (notices of violation) have been issued: 4 - for violating whole effluent toxicity limit, 5 — for violating BOD limit, 6 — for violating Fecal Coliform limit. Permitting Rationale — Toxicants The Division conducted EPA -recommended analyses to determine the reasonable potential for toxicants to be discharged at levels exceeding water quality standards/EPA criteria by this facility. For the purposes of the RPA, the background concentrations for all parameters were assumed to be below detection levels. The RPA uses 95% probability level and 95% confidence basis in accordance with the EPA Guidance entitled "Technical Support Document for Water Quality -based Toxics Control." The RPA included evaluation of dissolved metals' standards, utilizing a default hardness value of 25 mg/L CaCO3 for hardness -dependent metals. The RPA spreadsheets are attached to this Fact Sheet. The calculations included: As, Be, Cd, Total Phenols, Cr, Cu, CN, F, Pb, Hg, Mo, Ni, Se, Ag, and Zn. The new flow limit of 4.9 MGD was used for RPA. The discharge data on the EPA Form 2C and DMR reports was used for the RPA. The analysis indicates no reasonable potential to violate the surface water quality standards or EPA criteria. The proposed permit requires that EPA methods 200.7 or 200.8 (or the most current versions) shall be used for analyses of all metals except for total mercury. Permitting Rationale — Oxygen Consuming Waste Pollutants BOD Limits for BOD have been converted to secondary treatment standards since the facility now primarily treats domestic wastewater. Ammonia monitoring requirements are retained in the draft permit to provide data concerning levels of ammonia discharged to the Pigeon River (which may affect instream dissolved oxygen). Effluent dissolved oxygen is limited at no less than 6 mg/L based on the above discussion. Permitting Rationale — Nutrients Total phosphorus and total nitrogen monitoring is required by 15A NCAC 2b .0500. Monthly monitoring is required to assess the contribution of nutrients. Permitting Rationale —Conventional Pollutants The total suspended solids (TSS) limits have been converted to secondary treatment standards since the facility now primarily treats domestic wastewater. The temperature requirement is based on the State Rules per 15A NCAC 2B .0200. Page 3 of 5 Limitations for fecal coliform are based on the contribution of domestic wastewater from the Town of Canton and the requirements of 15A NCAC 2B .0200. Conductivity monitoring is required based on 15A NCAC 2B .0500 and remain unchanged until the new owner determines the type of wastewater that will be treated. Limitations for pH 6.0 —9.0 are based on 15A NCAC 2B .0200. Toxicity Testing (15A NCAC 2B.0200 and 15A NCAC 2B.0500) Current Requirement: Outfall 001 — Chronic P/F @ 90% using Ceriodaphnia Dubia Recommended Requirement: Outfall 001 — Chronic P/F @ 12.7% using Ceriodaphnia Dubia. This facility failed 4 toxicity tests in 2023. However, the subsequent tests passed, please see attached. All tests conducted in 2020, 2021, 2022, and 2024 passed. For the purposes of the permitting, the permitted flow was used in conjunction with the 7Q 10 summer flow to calculate the percent effluent concentrations to be used for WET tests for each facility.
