Facilities emitting radionuclides not listed in COMPLY or appendix E shall contact EPA to receive the informa- tion needed to determine dose. The source terms to be used for input into COMPLY shall be determined through the use of the measurement procedures listed in § 61.107 or the emission factors in appendix D or through alternative § 61.104procedures for which EPA has granted prior approval; or,(b) Facilities may demonstrate com- pliance with the emission standard in this subpart through the use of com- puter models that are equivalent to COMPLY, provided that the model has received prior approval from EPA headquarters. Any facility using a model other than COMPLY must file an annual report. EPA may approve an alternative model in whole or in part and may limit its use to specific cir- cumstances.§ 61.104 Reporting requirements.(a) The owner or operator of a facil- ity subject to this subpart must submit an annual report to the EPA covering the emissions of a calendar year by March 31 of the following year.
