Describe receiving stream features and pertinent downstream uses: The WWTP discharges into a zero flow stream behind the facility (7Q10 & 30Q2 = 0; DA = 1.49 sq. mile) Part II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS 1. a. Volume of Wastewater to be permitted: 0.0125 MGD (Ultimate Design Capacity) Self -monitoring data shows an average flow of 0.0018 MGD for 1992. b. What is the current permitted capacity of the Waste Water Treatment facility? Same as above. c. Actual treatment capacity of the current facility (current design capacity)? Same as above. d. Date(s) and construction activities allowed by previous Authorizations to Construct issued in the previous two years. NA e. Please provide a description of existing or substantially constructed wastewater treatment facilities; The existing facility is a 0.0125 MGD extended aeration package plant with sludge holding and chlorination. The effluent from the package plant goes into a fifty-four day polishing pond before being discharged from the cascade aerator to the creek. The boiler blowdown from the facility is routed around the package plant and into the polishing pond. The boiler water is then discharged with the domestic wastewater through a common outfall. f. Please provide a description of proposed wastewater treatment facilities. NA g• Possible toxic impacts to surface waters: None known. h. Pretreatment Program (POTWs only): NA 2.

Important SOC, JOC or Compliance Schedule dates: (Please indicate) NA 4. Alternative Analysis Evaluation: Thomasville Furniture (TFI) submitted an engineering study evaluating wastewater disposal alternatives to DEM on 1-29-93 as required by Part III (E) of their current permit. The findings are as follows: Spray Irrigation: A soils evaluation found that marginal soil exists for the installation of a spray irrigation system on twelve acres of TFI land. The costs are estimated at $162,400. Connection to Regional Sewer System: Two possibilities exist for TFI to connect to Lexington's sewer system. The first would involve 4.1 miles of a pump station and force main system to Hwy's 64 and 85 at a cost of $225,000. The second option would involve 1.8 miles of a P.S.F.M. if a proposed elementary school is relocated near TFI. The feasibility of this option will not be known until 1994. The estimated cost would be $145,100. Subsurface: A soils evaluation found that marginal soil exists on the TFI site for the installation of a LPP system on 5.7 acres (including repair area). The costs are estimated at $154,000. Other disposal options: The study also evaluated the option of continuing to discharge at the existing location and upgrading the WWTP to meet 5mg/1 BOD and lmg/1 NH3N. This was determined to be the least environmentally sound alternative with a cost of $165,700. 5. Other Special Items: None. PART IV - EVALUATION AND RECOMMENDATIONS The Thomasville Furniture Lumber plant has approximately 100 employees and manufactures parts for wood furniture. The package plant only receives domestic wastewater. The effluent from the NPDES Permit Staff Report Version 10/92 Page 3 package plant and the boiler are routed into a 54 day polishing pond before being discharged through a common outfall to the U.T. which is a "zero flow" stream. A review of the self -monitoring data shows that the facility was compliant with all final limits in 1992 except for one TSS Violation in March (Probably due to algae from the polishing pond). It is relevant to note that the system does not discharge every month since wastewater can be held in the polishing pond for extended periods of time. In addition to the engineering study, Part III (E) of their present permit also stated that the final limits are scheduled to change to 5 mg/1 BOD and 1 mg/1 NH3-N effective 8-1-95. This date should remain in the next permit even though monitoring data indicates that the system cannot meet the proposed new limits. The engineering report was received on 1-29-93 and concluded that "all three non -discharge alternatives are environmentally feasible." The report also stated that "that relocation of the discharge to a positive flowing stream was not environmentally feasible." Therefore, WSRO recommends reissuance of the permit with the following compliance schedule: 1) Submit complete plans and specifications to DEM for either a sewer line extension permit or a nondischarge permit on or before June 1, 1994. 2) Begin construction of the WWTP improvements in accordance with the approved plans by April 1, 1995. 3) Complete construction in accordance with the plans by August 1, 1995. (This coincides with the date that the limits change to 5 and 1).

Box 339 Thomasville, N.C. 27361-0339 SUBJECT: Engineering Study SFD/64 Lumber Plant NPDES Permit No. NC0023604 Davidson County Dear Mr. Masters: This letter is to acknowledge receipt of the engineering study prepared by ESE Biosciencies, Inc., for the Thomasville Furniture SFD/64 Lumber Plant. The engineering study was required by Part III (E) of the above permit due to the zero 7Q10 flow and the potential for ammonia toxicity in the receiving stream. A review of the report indicates that the information is thorough and complete. Our office is in agreement with the report's conclusion that continuing to discharge at the existing location is the least environmentally sound alternative once the limits become more restrictive. Therefore, Thomasville Furniture should proceed with the necessary planning and funding in order to implement one of the three non -discharge alternatives outlined in the report. As you are aware, the NPDES permit is presently up for renewal. The new permit will contain a specific timetable requiring Thomasville Furniture to implement the findings of the study. It is expected that the permit will require the elimination of the discharge from the SFD/64 Lumber Plant on or before August 1, 1995. This is the date that the 5 mg/1 BOD and 1 mg/1 NH3-N limits are scheduled to become effective. 8025 North Point Boulevard, Suite 100, Winston-Salem, NC 27106-3203 • Telephone 919-896-7007 • FAX 919-896-7005 An Equal Opportunity Affirmative Action Employer Mr. David R.
