Facility and Address: KAY 0 2 1990 Western High School 1731 North NC 87 TLU""ruOAt SiiHORT EAMNiCN Elon College, NC 27253 2. Date of Investigation: April 25, 1990 3. Report Prepared by: Eric Galamb 4. Persons Contacted and Telephone Number: Neil Moore (919) 227-3601 5. Directions to Site: Travel north on Highway 87 from Burlington approximately 3 miles to SR 1530. The school is located on the southeast corner of the intersection. 6. Discharge Point - Latitude: 360 08' 05" Longitude: 790 29' 25" Attach a USGS Map Extract and indicated treatment plant site and discharge point on map. USGS Quad No. C21 NW or USGS Quad Name Lake Burlington 7. Size (land available for expansion and upgrading): There is ample area available for expansion and upgrading. 8. Topography (relationship to flood plain included): The sandfilter bed is approximately 70 feet above the Haw River. 9. Location of nearest dwelling: Dwellings are not close to the treatment facility. 10. Receiving stream or affected surface waters: a. Classification: WSIII-NSW b. River Basin and Subbasin No.: 030602 c. Describe receiving stream features and pertinent downstream uses: The pertinent downstream uses are consistent with the WSIII classification. PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS 1. Type of wastewater: 100% Domestic Industrial a. Volume of Wastewater: 0.0115 MGD b. Types and quantities of industrial wastewater: c. Prevalent toxic constituents in wastewater: d. Pretreatment Program (POTWs only) in development approved should be required not needed X 2. Production rates (industrial discharges only) in pounds a. highest month in the last 12 months b. highest year in last 5 years 3. Description of industrial process (for industries only) and applicable CFR Part and Subpart: 4. Type of treatment (specify whether proposed or existing): Existing: A 11,500 gallon septic tank, a dosing tank, 40' x 70' surface sand filter with a chlorine contact tank. 5. Sludge handling and disposal scheme: The sludge hauler is McPherson Septic Tank Service. 6. Treatment plant classification: Class I 7. SIC Code(s) 8211 Wastewater Code(s) 03 PART III - OTHER PERTINENT INFORMATION 1. Is this facility being constructed with Construction Grants Funds (municipals only)? 2. Special monitoring requests: Total residual chlorine and fecal coliform - weekly. 3. Additional effluent limits requests: 4. Other: PART IV - EVALUATION AND RECOMMENDATIONS A chlorine contact chamber has been installed this month. The chlorine contact chamber was constructed without an authorization to construct and without the necessary plans. The WSRO suspects that the chamber is too small for a 30 minute detention time. The WSRO recommends that the school test to see if adequate disinfection occurs without excessive residual chlorine levels. If more detention time is necessary, the WSRO will require the school to enlarge the chamber to accommodate 1000 gallons. It is requested that fecal coliforms and total residual chlorine be sampled weekly. The WSRO recommends that the permit for Western High School be reissued. The septic tank and dosing tank were full of solids. The school maintenance department will pump these chambers on April 27, 1990.
