TYPE OF PERMIT BEING APPLIED FOR (check one): New X Renewal Major modification FOR PERMIT RENEWAL OR MAJOR MODIFICATION: Permit number WYO Expiration Date: _Sept. 30, 2018 For permit modifications, please attach a letter explaining modifications requested. B. DESCRIPTION OF THE TREATMENT SYSTEM: (e.g., Includes a mechanical bar screen with a manual bypass bar screen and a girt chamber, flows through an ultraviolet (UV) disinfection unit, etc.). You may include description on separate sheet. The City Mountain View wastewater treatment facility (WWTF) process starts with an automated coarse screen before the influent is pumped to an anaerobic cell which is followed by a complete mix cell. The complete mix cell discharges to the Biodome cell that transitions from fixed aeration to Biodomes with Hexprotect floating cover. The former SAGR unit constructed in 2012 has been excavated and is utilized as an aerated finishing cell before the effluent is discharged to the chlorination/dechlorination chamber and the outfall to Smith s Fork. Also, please provide a site sketch showing the processes of the treatment plant, including all bypass piping and all backup power sources or redundancy in the system. This includes a water balance showing all treatment units, including disinfection, and showing daily average flow rates at influent and discharge points, and approximate daily flow rates between treatment units C. IDENTIFICATION OF THE TYPE OF COLLECTION SYSTEM USED BY THE TREATMENT WORKS: (check one): A separate sanitary system X OR A combined storm and sanitary system Estimate of the percent of sewer line that each type comprises: N/A How many bypass outfalls does this facility contain? None How many constructed emergency overflow outfalls does this facility contain? None WYPDES Application for Sewage Treatment Facilities Page 1

Box 249 City, State, and Zip Code Mountain View, WY Is collection system (check one): A separate sanitary system X or A combined storm and sanitary system? Is collection system (check one): Owned X or maintained by the municipal entity? (Additional pages may be added as necessary) Name of Municipal Entity #2 Population Mailing Address City, State, and Zip Code Is collection system (check one): A separate sanitary system or A combined storm and sanitary system? Is collection system (check one): Owned or maintained by the municipal entity? G. FLOW RATE: for the past three years provide (in MGD): The facility s design flow rate (the wastewater flow rate that the plant was built to handle): 0.68 mgd influent rate, 0.34 mgd effluent rate, subsequent modifications in 2017 gives the facility to capacity to accommodate a 0.55 mgd effluent rate. The facility s annual average daily effluent flow rate: mgd. The facility s maximum daily flow rate: ) mgd June 2, 2017 H. PRETREATMENT PROGRAM: Does the treatment works have, or is it subject to, an approved pretreatment program? Yes X No Provide the number of Significant Industrial Users (SIUs) and Categorical Industrial Users (CIUs) that discharge to the treatment works. Number of non-categorical SIUs. None Number of CIUs. None I. OUTFALL INFORMATION: Provide the following information for each outfall: Outfall Information Discharge Point Number # Immediate Receiving Stream Main stem (nearest perennial stream) Distance from outfall to main stem (stream miles) Quarter/ Quarter Section Township Range Latitude (decimal degrees to 5 decimal places) Longitude (decimal degrees to 5 decimal places) 001 Smiths Fork Smiths Fork 0 SW SE 17 T15 N R114W WYPDES Application for Sewage Treatment Facilities Page 4

6 (Additional pages may be added as necessary) FOR ALL MINOR AND MAJOR FACILITIES WITH A DESIGN FLOW GREATER THAN OR EQUAL TO 0.1 MGD Please Complete the Following J. FLOW: What is the current average daily volume of inflow and infiltration in gallons per day? Winter months: 0.10 mgd (11% of base flow) May-June 0.27 mgd (300% of base flow) What steps are being taken to minimize inflow and infiltration (I&I)? A comprehensive program to map the sanitary sewer system to a GIS is underway. The sewer mains are being video logged to identify areas of infiltration and inflow. Specific steps as appropriate are taken in areas of observable I&I to eliminate the problems. The school campus has a high rate of I&I which is being addressed with the school system. The entire community is located in a high mountain valley with a seasonally high groundwater level less than the depth of any basements and the depth of burial of the sanitary sewer system. The I&I from illicit basement sump pumps connected to the sanitary sewer and leaky residential service lines is a difficult practical and political problem to address. A public education effort is on-going to encourage homeowners to address their contribution to high I&I flows. K. SCHEDULED IMPROVEMENTS AT THE PLANT For each outfall, provide a list of improvements to the plant that have been scheduled for the next five years. For each improvement, provide the commencement and completion date of construction, commencement date of discharge, and attainment of operational level. Have appropriate permits/clearances concerning other Federal/State requirements been obtained? X_Yes No Describe briefly: The BioDome upgrade was completed in 2017 using DEQ/WQD Permit to Construct L. PLEASE PROVIDE A TOPOGRAPHIC MAP (or other map if a topographic map is unavailable) extending one mile beyond the property boundaries of the treatment plant, depicting the facility and each of it s: 1. Intake and discharge structures 2. Hazardous waste treatment storage or disposal facilities 3. Wells where fluids from the facility are injected underground 4. Wells, springs, drinking water wells and any other surface water bodies that are listed in public records or otherwise known to the applicant in the map area. 5. Sewage sludge management facilities, including on-site treatment, storage, and disposal sites. 6. Location(s) at which waste classified as hazardous under RCRA enters the treatment plant by truck, rail or dedicated pipe. 7. Access route to the facility (see Q below). M. PLEASE PROVIDE A DIAGRAM showing the processes of the treatment plant, including all bypass piping and all backup power sources or redundancy in the system. Also, provide a narrative description of the diagram. NARRATIVE: The wastewater flow from the Town of Mountain View is conveyed to the WWTF by a 1 1/3 mile long trunk line with no service taps in that distance. The flow is measured by a Parshall flume before being screened to remove non-digestible debris. After screening the flow is pumped to an anaerobic cell for initial digestion of the biodegradable wastes. From the anaerobic cell the flow moves to a fully mixed aerated cell. The fully mixed aerated cell is followed by a partially mixed cell that has been populated with 80 Biodomes which provide a fixed film media to improve removal of low levels of BOD5 and ammonia. The flow from the Biodome cell can either be discharged directly to disinfection or routed through an aerated pond created by removing the rock from a former SAGR cell. The discharge is then chlorinated, dechlorinated, and sent to Outfall #1. For emergencies and maintenance of the WWTF treatment train, the cells from the previous lagoon system have been maintained and can be used to store bypassed flows for up to 30 days while providing some treatment. The liquid in the old lagoons can be pumped back through the current WWTF to provide complete treatment. N. PLEASE PROVIDE THE FOLLOWING INFORMATION FOR EACH OUTFALL, INCLUDING BYPASS POINTS, THROUGH WHICH EFFLUENT IS DISCHARGED, AS APPLICABLE: 1. Outfall number 1 WYPDES Application for Sewage Treatment Facilities Page 5
