Underground uranium mine definition

Underground uranium mine means a man-made underground excavation made for the purpose of removing ma- terial containing uranium for the prin- cipal purpose of recovering uranium.[54 FR 51694, Dec. 15, 1989, as amended at 65FR 62151, Oct. 17, 2000]§ 61.22 Standard.Emissions of radon-222 to the ambi- ent air from an underground uranium mine shall not exceed those amounts that would cause any member of the public to receive in any year an effec- tive dose equivalent of 10 mrem/y.§ 61.23 Determining compliance.(a) Compliance with the emission standard in this subpart shall be deter- mined and the effective dose equivalent calculated by the U.S. Environmental Protection Agency (EPA) computer code COMPLY-R. An underground ura- nium mine owner or operator shall cal- culate the source terms to be used for input into COMPLY-R by conducting testing in accordance with the proce- dures described in appendix B, Method 115, or(b) Owners or operators may dem-onstrate compliance with the emission standard in this subpart through the use of computer models that are equiv- alent to COMPLY-R provided that the 40 CFR Ch. I (7–1–20 Edition)model has received prior approval from EPA headquarters. EPA may approve a model in whole or in part and may limit its use to specific circumstances.[54 FR 51694, Dec. 15, 1989, as amended at 65FR 62151, Oct. 17, 2000]§ 61.24 Annual reporting requirements.(a) The mine owner or operator shall annually calculate and report the re- sults of the compliance calculations in§ 61.23 and the input parameters used in making the calculations. This report shall cover the emissions of a calendar year and shall be sent to EPA by March 31 of the following year. Each report shall also include the following information:
