USGS Quad No. B19NW or USGS Quad Name Mayodan 7. Size (land available for expansion and upgrading): 15+ Acre Site 8. Topography (relationship to flood plain included): Lagoons elevated above receiving stream. 9. Location of nearest dwelling: Approximately 750' 10. Receiving stream or affected surface waters: UT to Mayo River a. Classification: WS-III b. River Basin and Subbasin No.: Roanoke 03-02-02 C. Describe receiving stream features and pertinent downstream uses: Low flow stream enters Mayo River approximately 900' from discharge (below City intake) PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS 1. Type of wastewater: % Domestic 100% Industrial (Filter backwash) a. Volume of Wastewater: .03 MGD NOL (Design Capacity) b. Types and quantities of industrial wastewater: Occasional trickle of a discharge if any from backwashing of filters. c. Prevalent toxic constituents in wastewater: Unknown d. Pretreatment Program (POTWs only): N/A in development approved should be required not needed X 2. Production rates (industrial discharges only) in pounds per day: a. highest month in the last 12 months lbs/day b. highest year in last 5 years lbs/day .875 mgd of drinking water produced in 1990 3. Description of industrial process (for industries only) and applicable CFR Part and Subpart: 4. Type of treatment (specify whether proposed or existing): Two (2) Existing 70' x 50' x 80' settling lagoons. (Used alternately). 5. Sludge handling and disposal scheme: Settled material to be hauled to Landfill for the first time since the WTP was built 11 years ago. 6. Treatment plant classification: I 7. SIC Code(s) 4941 Wastewater Code(s) 21 PART III - OTHER PERTINENT INFORMATION 1. Is this facility being constructed with Construction Grants Funds (municipals only)? N/A 2. Special monitoring requests: N/A 3. Additional effluent limits requests: N/A 4. Other: WTP produces 14,300 gpd of backwash to the lagoons. PART IV - EVALUATION AND RECOMMENDATIONS The lagoons appear to be working very well. Very little (if any) discharge occurs. One lagoon is to be cleaned of sediment shortly which will increase capacity significantly. Sediment will be landfilled. WSRO recommends renewal of the permit.
