Lee Fleming, Jr., Supervisor State Engineering Unit (1 FROM : Dennis R. Ramsey, Regional SupervisorJ Fayetteville Regional Office SUBJECT: Procedure 4, Sewer Line Extension and Construction of New 45 GPM Pump Station Town of Ellerbe Wastewater Treatment Plant Ellerbe, • County 1. WASTEWATER TREATMENT PLANT TO RECEIVE PROPOSED WASTE: Ellerbe Wastewater Treatment Lagoon 2. DESIGN CAPACITY: 0.09 MGD 3. AVERAGE MONTHLY FLOW: *.05 MGD 4. AVERAGE PLANT EFFICIENCY: Influent 1) Effluent 1 Reduction % *BOO 329.5 24.3 93% *TSS 314.0 50.0 84% 5. The existing NPDES Permit (NC0021784) for the Town of Ellerbe Wastewater Treatment Plant is in effect until December 31, 1982. The existing dis- charge point at Tom's Creek has final effluent limitations of: BODS a 30 mg/l and TSS ■ 90 mg/l. 6. PROTECT WATER QUALITY: With existing treatment system. No 7. QUANTITY AND TYPE OF WASTEWATER FROM PROPOSED EXTENSION: 10,000 gallons/day - Domestic waste from apartment complex 8. VOLUME FROM PREVIOUSLY APPROVED PROJECTS NOT YET COMPLETE: None known *Calculations obtained from data supplied by The Town of Ellerbe Wastewater Treatment Plant in its monthly self -monitoring reports for the months of August 1980 through July 1981. W. Lee Fleming Page 2 9. OTHER PERTINENT INFORMATION: The Town of Ellerbe operates a Class I plant that has a design flow of .09 mgd. The plant's current average flow is approximately .053 mgd. Although this plant produces a good quality effluent, it has not been able to meet the final effluent limitations contained in its NPDES permit. The discharge from the Ellerbe Wastewater Treatment Plant is to Tom's Branch, a Class "V stream in the Yadkin -Pee Dee River Basin. The 7Q10 of this stream at the point of discharge is 0.05 cfs. The need for additional housing and normal growth for Ellerbe was necessary, therefore, the Town requested a Special Order by Consent from the Environmental Management Commission to allow the town to provide sewer service for a 50 unit apartment complex and approximately 77 existing single family dwellings that are experiencing septic tank failure. In order to determine the effect that allowing the requested additional wastewater flow into the Ellerbe system might have on the receiving stream, an In -Stream Assessment was conducted by our Technical Services Branch. This assessment was based on allowing the discharge to be increased by the addition of 35,000 gpd, while assuming a BOD of 40 mg/l and a NH of 15 mg/l. The assessment concluded that the additional flows will3have no detrimental effect above the effluent caused by the plant's present loading. The Commission approved and accepted the Town's Special Order by Consent request on June 11, 1981 and this Special Order by Consent will expire July 1, 1983. This Special Order by Consent will have the following Interim Effluent Limitations in effect until completion of Ellerbe's 201 Facility Plan: Interim Effluent Limitations Effluent Characteristic kg/day (lbs/dy) Monthly Weekly Average Average Flow, M3/day (MGD) BOD, 5-day 13.6 30 20(45) TSS 41 90 72.6(160) Discharge Limitations Other Di Cations Average Maximum 341(.09) 40 m9/1 60 mg/l 120 mg/l 180 mg/l After completion of the modification proposed in the Town's 201 plan. the Ellerbe Wastewater Treatment Plant should be in compliance with final effluent limitations. The 10,000 gpd additional flow of domestic waste is from the construction of a 45 gpm pump station and approximately 900 l.f. of 3 inch force main. The subject permit application is for a portion (10,000 gallons) of the 35,000 gpd additional flow approved in the Town of Ellerbe's Special Order by Consent. The 10,000 GPD flow will come directly from the 50 unit apartment complex and the remaining 25,000 GPD will come from approximately 77 single family dwellings once the appropriate connector lines are constructed. Originally, the pump station was designed for a 30 gpm pump, however, according to Evan Manier, of Moore Gardner and Associates, this was revised to a 45 gpm pump station. W. Lee Fleming Page 3 10. RECOMMENDATION It is the recommendation of processed and an appropriate of a 45 gpm pump station and this office that the permit application be permit be issued to authorize the construction approximately 900 l.f. of 3 inch force main.
