Attention: Kathy Shreve

Subject: Re-submittal Renewal Application, WYPDES Permit: WY0026689

Enclosed please find Kennecott Uranium Company’s application to renew the Wyoming Pollutant Discharge Elimination System (WYPDES) Permit WY0026689. Please note that this is Kennecott's second time submitting this renewal application. The first application was submitted on 7/28/2020. The application that is attached address questions that Ms. Kathy Shreve had. The following applies to this renewal application:

• This is an application for renewal of an existing permit (WY0026689). • Kennecott Uranium Company is sending this letter to notify your office that we do intend to renew WYPDES Permit WY0026689 and ask that the permit not be canceled on the 7/31/2020 permit expiration date. • Unfortunately, the previous site supervisor retired at the beginning of 2020 and contact information was not changed so the notification was not received by our new supervisor in order for the application to be completed with enough time for it to be reviewed and accepted/issued by WY DEQ before the 7/31/2020 permit expiration date. No discharge under this permit has occurred since spring 1983 (a period of over thirty-seven (37) years) following cessation of mining operations at the Sweetwater Uranium Project following a drop in uranium prices and loss of a uranium supply contract.

If you have any questions please do not hesitate to contact me.

Sincerely yours,

All applicants must analyze and submit the results for the constituents listed below (see Table 1, Appendix B). Biochemical Oxygen Demand (BOD5) Ammonia (as N) Chemical Oxygen Demand Temperature Total Organic Carbon pH Total Suspended Solids Color of Discharge

Primary Industries: A primary industry is any industry listed under the Primary Industrial Category in Appendix B, Table II.

If you are a primary industry (refer to Appendix B, Table II), samples must be collected for all fractions identified in Appendix B, Table I. For Appendix B, Tables IIA – III, mark “X” in the Required Testing column for each fraction related to your industry and provide the sample result. Sample results must be provided for each outfall that has the potential to discharge process wastewater.

For Appendix B, Table IV, mark “X” in column “Believed Present” for each pollutant you know or have reason to believe is present. Mark “X” in column “Believed Absent” for each pollutant you believe is absent. If an applicable federal effluent limitations guideline limits the pollutant through permit effluent limitations, the applicant must report quantitative data. For every pollutant discharged which is not so limited in an effluent limitations guideline, the applicant must either report quantitative data or briefly describe the reasons the pollutant is expected to be discharged.

For Appendix B, Table V, circle the pollutants you know or have reason to believe are present. For every pollutant from Table V expected to be discharged, from each outfall, provide a brief description of the reasons the pollutant is expected to be discharged, and report any quantitative data you may have.

Base your determination of whether a pollutant will be present in your discharge on your knowledge of the facility’s raw materials, maintenance chemicals, intermediate and final products, byproducts, and any analyses of your effluent or of any similar effluent. You may also provide the determination and the estimates based on available in-house or contractor’s engineering reports or any other studies performed on the facilities.

Secondary Industries: A secondary industry is an industry that is not listed under the primary Industrial Category in Appendix B, Table II.

For Appendix B, Tables IIA – III, mark “X” in column “Believed Present” for each pollutant you know or have reason to believe is present. Mark “X” in column “Believed Absent” for each pollutant you believe is absent. If you mark column “Believed Present” for any pollutant, you must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be discharged in concentrations of 10 ppb or greater. If you mark column “Believed Present” for acrolein, acrylonitrile, 2,4 dinitrophenol, or 2-methyl-4, 6 dinitrophenol, you must provide the results of at least one analysis for each of these pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater. Otherwise, for pollutants for which you mark column “Believed Present”, you must either submit at least one analysis or briefly describe the reasons the pollutant is expected to be discharged.

Page 5 of 20 For New Industrial Facilities: For Appendix B, Tables IIA – IV, mark “X” in column “Believed Present” for each pollutant you know or have reason to believe is present. Mark “X” in column “Believed Absent” for each pollutant you believe is absent. For each pollutant marked as “Believed Present” provide an estimated daily maximum concentration in the “Water Sample Results” column. For Appendix B, Table V, circle the pollutants you know or have reason to believe are present (no estimated daily maximum concentrations are required).

Each applicant must report the existence of any technical evaluation concerning the wastewater treatment that will be utilized, along with the name and location of similar plants, if information is available.

25. Use Appendix B, Table VI to list any of the pollutants, for which you are not required to submit a water quality analysis, listed in Appendix B, Tables II – V below which you know or have reason to believe is discharged or may be discharged from any outfall. For every pollutant you list, briefly describe the reasons you believe to be present and report any analytical data in your possession. 26. Do you have any knowledge or reason to believe that any biological test for acute or chronic toxicity has been made on any of your discharges or on receiving water in relation to your discharge within the last three years?

YES x NO

If yes, identify the tests and describe their purpose below: ______

27. Dioxin testing: Each applicant for existing facilities must report qualitative data, generated using a screening procedure not calibrated with analytical standards for 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) if it :

i. Used or manufactures 2,4,5-trichlorophenoxy acetic acid (2,4,5,-T), 2-(2,4,5-trichlorophenoxy) propanoic acid (Silvex, 2,4,5,- TP); 2-(2,4,5-tricholorophenoxy) ethyl 2,2-dichloropropionate (Erbon); 0,0-dimethyl 0-(2,4,5-trichlorophenyl) phosphorothioate; 2,4,5-trichlorophenol (TCP); or hexachlorophene (HCP); or ii. Knows or has reason to believe that TCDD is or may be present in an effluent. iii. Applicants for new facilities must report if 2,3,7,8 Tetrachlorodibenzo-P-Dioxin (TCDD) may be discharged if any of the pollutants defined in 31.i above are used or manufactured or if there is reason to believe that TCDD will or may be present in the effluent.

28. For applications for existing facilities, has the facility ever exceeded permit limits or water quality standards?

x YES Many years ago NO If yes, a. Which constituents? Total Suspended Solids (TSS) / Radium-226 Oil and Grease

b. Has the exceedance been addressed? Yes, at the time. Facility is no longer dicharging.

c. Describe how the exceedance was addressed.Treatment testing using coagulants was done in April 1982 to address TSS. Radium-226 exceedances were addressed via increasing barium chloride addition rates. The Oil and Grease exceedances occurred when discharge commenced and were believed to be due to contamination related to the construction of the settling ponds. d. If the facility has never discharged or has not yet been constructed, please indicate below.

YES x NO Report the existence of any technical evaluation concerning the applicant’s wastewater treatment, along with the name and location of similar plants. ______A similar plant was operated at the Big Eagle Mine, permitted under permit WY0025950 and planned for the Jackpot Mine under permit WY0033952
