Easley, Governor William G. Ross, Jr., Secretary Gregory J. Thorpe, Ph.D., Acting Director December 21, 2001 The Honorable Johnny Rogers Town of Rosman P.O. Box 636 Rosman, North Carolina 28772 Avi7rA NCDENR Subject: Speculative Limits for Rosman WWTP NPDES Permit No. NC0021946 Transylvania County Dear Mayor Rogers: This letter is in response to the request for speculative effluent limits submitted by WK Dickson for the expansion of the Rosman WWTP. The expansion flow of 0.25 was targeted for the existing discharge point in the French Broad River. The staff of the NPDES Unit of the Point Source Branch has reviewed this request and will provide speculative effluent limits. However, additional information has been reviewed in Rosman's October 2001 preliminary engineering report and environmental assessment. The Division of Water Quality recommends that Rosman more closely evaluate the option of connection to the Brevard WWTP. The regionalization of wastewater treatment facilities remains a primary goal of DWQ and it would appear that the connection to the Brevard WWTP is a viable option for this facility. This segment of the French Broad River where Rosman currently discharges has a stream classification of WS-III Trout. The best usage of these waters is as a source of water supply for drinking, culinary, or food processing. The trout designation dictates that these are waters that have conditions, which shall sustain and allow for trout propagation and survival of stocked trout on a year-round basis. The discharge point has an estimated drainage area of 67.9 square miles, with an average flow of 240 cfs, a summer 7Q10 of 55.5 cfs and a winter 7Q10 of 63.4 cfs. There are no other dischargers near this site. Based on available information, the tentative effluent limits for oxygen -consuming constituents of the Rosman WWTP discharge at the expansion flow of 0.25 MGD are included on the attached effluent sheet. Upon formal permit application for the expansion flow, if there is an industrial wastewater constituency, an evaluation of limits and monitoring requirements for metals and other toxicants will be addressed at that time. The Division of Water Quality is requiring chlorine limits for all new or expanding dischargers proposing the use of chlorine for disinfection. The process of 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Telephone (919) 733-5083 FAX (919) 733-0719 An Equal Opportunity Affirmative Action Employer Internet: http://h2o.enr.state.nc.us/ Rosman WWTP Speculative Limits Page 2 The Division of Water Quality is requiring chlorine limits for all new or expanding dischargers proposing the use of chlorine for disinfection. The process of chlorination/dechlorination or an alternate form of disinfection, such as ultraviolet radiation, should allow the facility to comply this requirement. It should also be noted that upon permit renewal or the expansion of the wastewater treatment plant, the facility would have to begin influent monitoring of BOD5 and Total suspended residue. In addition, the monthly average effluent BOD5 and Total Suspended Residue concentrations shall not exceed 15% of the respective influent value, therefore there must be at least an 85% removal rate (per the secondary treatment requirement per 40 CFR Part 133). Final NPDES effluent limitations will be determined after a permit application has been submitted to the Division. If there are any additional questions concerning this matter, please feel free to contact Jackie Nowell of my staff at (919) 733-5083 ext. 512. Respectfully, David A.

Spec request was first submitted to the Asheville RO on July 20, 2001 and was transferred to the Central Office in September 2001. On November 15, 2001, WK Dickson resubmitted request. Estimated for flows at existing discharge point in the French Broad River DA= 67.9 mi2 QA= 240 cfs s7g10=55.5 cfs w7q10=63.4 cfs The French Broad River is not listed on the 2000 303d list Summary of Model results Must protect for a DO instream standard of 6 mg/1 because of the Trout classification for the French Broad River. Level B model indicates that the river can assimilate the wastewater at the expansion flow of 0.25 MGD. Secondary limits of BOD5 = 30 mg/1 will protect the DO standard of 6 mg/1 instream. Model setup One segment with three reaches. First reach, 0.6-mi. length, to the confluence of Browns Mill Creek. Second reach, 0.3 mi. length, to the confluence of Middle Fork French Broad River Third reach, 0.1 mile length — to just upstream of the confluence of the East Fork French Broad River. Ran summer and winter models at flow of 0.25 MGD. Model run predicted summer DO minimum of 7.67 mg/1. Predicted winter DO minimum was 9.64 mg/1. No effluent DO or summer/winter NH3 limits are needed.

The effluent is discharged into the French Broad River, south of Rosman, as shown in the attached figure. The facility operates under the NPDES permit number NC0021946. We are requesting a preliminary waste -load allocation, effluent limitations and monitoring requirements for the expansion so that we may complete the alternatives analysis for this project. Currently, the wastewater is primarily domestic in nature and is not likely to change in the future. If you have any questions, or require additional information, do not hesitate to call.
