• Denison will use the resulting Rn-222 and flow rate measurements to calculate the effective dose <br />equivalent resulting from mine emissions. The EPA computer code COMPLY-R will be used and the <br />output from COMPLY-R will be compared to the 10 mrem/yr emission standard. Denison may also <br />demonstrate compliance with the 10 mrem/yr emission standard through the use of computer models that <br />are equivalent to COMPLY-R if the model has received prior approval from EPA headquarters. If <br />Denison would like to use a model other than COMPLY-R, Denison will submit a proposal for the model <br />prior to its use. <br />As per 40 CFR 61, Subpart B, Denison will calculate and report the results of the compliance modeling <br />each year. This annual report will include the emissions of a calendar year and will be sent to EPA <br />Region 8 by March 31 st of the following year. Denison will include the following information in each <br />annual report: <br />1. The name and location of the mine. <br />2. The name of the person responsible for the operation of the facility and, if different, the name of <br />the person preparing the report. <br />3. The results of the emissions testing conducted and the dose calculated. <br />• 4. A list of the stacks, vents, or other points where radioactive materials are released to the <br />atmosphere, including their location, diameter, flow rate, effluent temperature, and release height. <br />5. A description of the effluent controls that are used on each stack, vent, or other release point if <br />applicable; a description of the effluent controls used inside the mine if applicable; and an <br />estimate of the efficiency of each control method or device. <br />6. Distances from the points of release to the nearest residence, school, business, or office and the <br />nearest farms producing vegetables, milk, and meat. <br />7. The values used for all other user-supplied input parameters for the computer model (such as <br />meteorological data) and the source of these data. <br />Per the requirements of 40 CFR Part 61, Subpart B, each report will be signed and dated by a corporate <br />officer in charge of the facility and will contain the following declaration immediately above the signature <br />line: "I certify under penalty of law that I have personally examined and am familiar with the information <br />submitted herein and based on my inquiry of those individuals immediately responsible for obtaining the <br />information, I believe that the submitted information is true, accurate and complete. I am aware that there <br />are significant penalties for submitting false information including the possibility of fine and <br />imprisonment. See, 18 U.S.C. 1001." <br /> <br />c:`dO mmu and aeluWtwoodwadVOal aelinpue ipmry imerM 61aWWauday mim mmpliaruc pun_MflAac <br />4-2
