If the mine is not in compliance with the 10 mrem/yr emission standard in the calendar year covered by <br />the report, Denison will report Rn-222 emissions to EPA Region 8 on a monthly basis. The first monthly <br />report would include emissions from March of that year and would be due April 3&. Subsequent reports <br />would be due 30 days after the end of the month. Denison would submit these monthly reports to EPA <br />Region 8 until the EPA determined that the monthly reports are no longer necessary. Denison would <br />include the following information in each monthly 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 />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 />8. All controls or other changes in operation of the facility that will be or are being installed to bring <br />the facility into compliance. <br />9. If the facility is under a judicial or administrative enforcement decree, the report will describe the <br />facilities performance under the terms of the decree. <br />Denison will maintain records documenting the source of input parameters, including the results of all <br />measurements upon which they are based, the calculations and/or analytical methods used to derive <br />values for input parameters, and the procedure used to determine compliance. The documentation will <br />allow an independent auditor to verify the accuracy of the determination made concerning the facility's <br />compliance with the standard. These records will be kept at the mine site or by the owner or operator for <br />at least five years. They will be made available upon request for inspection by the EPA Region 8. <br />Monitoring and recordkeeping requirements are summarized in Table 4-1 below. <br />• <br />4-3 <br />c:Woc?ts and seltmgstcwoodwwMbcal se1UngA1wmmary ime W fiWdk4V.&y mims wnpliance plan dm9AM
