OUTFALL <br />NUMBER <br />WASTEWATER <br />SOURCE <br />TREATMENT USED <br />AVG <br />FLOW, <br />MGD* <br />DESIGN ** <br />FLOW, <br />MGD <br />DAILY MAX FLOW, MGD <br />001 <br />APPLICATION for DISCHARGES ASSOCIATED WITH HARDROCK MINING AND /OR MILLING <br />16. Used or Manufactured Toxics: The applicant must provide a list of any toxic products which the applicant currently uses or <br />manufactures as an intermediate or final product or byproduct. <br />N/A <br />17. Flow Measurement: What method of flow measurement will be used for each discharge point (e.g., v notch weir, pump capacity, <br />parshall flume, etc.)? Designate whether currently installed or proposed. Identify the minimum and maximum flow measurement capability. <br />List the last date calibrated. <br />(a) Timed flow into 1 gallon container; calculate GPM <br />(b) A v -notch is purposed for the future. <br />18. Improvements: Please provide a description of any abatement requirement, abatement project and projected final compliance dates if <br />subject to any present requirements or compliance schedules for construction, upgrading or operation of waste treatment equipment. List <br />any changes from previous permit. <br />N/A <br />19. Land Application: Is or will land application of any wastewater be practiced? II NO Li YES <br />If Yes, please provide a copy of thematerial submitted to the Colorado Division of Minerals and Geology on the discharge and <br />include a copy of the CDMG approval where applicable. Briefly describe the process <br />20. Flows and Treatment: Please provide a detailed narrative description for each type of process, operation, storage or production area <br />which contributes wastewater to the effluent for each outfall, including process wastewater, cooling waters, domestic wastewater and <br />stormwater runoff; the flows for each process and a description of the treatment the wastewater receives including the ultimate disposal of <br />any solid or fluid wastes other than by discharge. Processes, operations or production areas may be described in general terms. The <br />average flow of point sources composed of stormwater may be estimated. The basis for the rainfall event and the method of determination <br />must be indicated. <br />List the outfall number for each discharge point. List all sources of wastewater for each outfall and give the 30 day average flow and daily <br />maximum flow. Estimate the flow contributed by each source if no data is available, and for stormwater, you may use any reasonable <br />measure of duration, volume or frequency. Describe each treatment unit. Indicate the 10 -year, 24 -hour equivalent volume used in <br />designing the treatment system and the system's actual volume, excluding solids retention and any "permanent pool" that may be <br />provided. Indicate if extra capacity is provided for mine water and /or other non -storm related-flows and how this volume was determined. <br />Indicate what type(s) of discharge structure each outfall has and how flow is discharged - whether it discharges automatically or manually. <br />If your flows vary significantly or if you anticipate significant <br />changes in flows during the next 5 years, specify which flows will change and explain why they will change. Describe the ultimate disposal <br />of any solid or liquid waste not discharged. (Specify receiving waters(s) in table for item 21.) <br />n the treatment facilities may be requested during application review. <br />*MGD - Million gallons /day <br />* *If sediment pond, indicate approximate volume of water. <br />Revised 4/2011 <br />
