35-11-206. Operating permit requirements and conditions.
(a) Every permit issued under the operating permit program shall include enforceable emission limitations and standards, a schedule of compliance, a requirement that the permittee submit to the department no less often than every six (6) months, the results of any required monitoring, and other conditions as are necessary to assure compliance with applicable requirements established pursuant to this article and the Clean Air Act.
(b) The department may by rule prescribe procedures and methods for determining compliance and for monitoring and analysis of pollutants regulated under the Clean Air Act and this article, but continuous emissions monitoring need not be required if alternative methods are available that provide sufficiently reliable and timely information for determining compliance. Nothing in this subsection shall be construed to affect any continuous emissions monitoring requirement of title IV of the Clean Air Act, or where required elsewhere in the Clean Air Act.
(c) Every permit issued under the operating permit program shall set forth inspection, entry, monitoring, compliance certification and reporting requirements to assure compliance with the permit terms and conditions. Monitoring and reporting requirements shall conform to any applicable regulation under subsection (b) of this section. Any report required to be submitted by a permit issued to a corporation under the operating permit program shall be signed by a responsible corporate official, who shall certify its accuracy.
(d) The department may, after notice and opportunity for public hearing, issue a general permit covering numerous similar sources. Any general permit shall comply with all requirements applicable to permits under title V of the Clean Air Act and the operating permit program. No source covered by a general permit shall thereby be relieved from the obligation to file an application under W.S. 35-11-205.
(e) The department may issue a single permit authorizing emissions from similar operations at multiple temporary locations. No such permit shall be issued unless it includes conditions that will assure compliance with all the requirements of the operating permit program and the Clean Air Act at all authorized locations, including, but not limited to, ambient standards and compliance with any applicable increment or visibility requirements under part C of title I of the Clean Air Act. Any such permit shall in addition require the owner or operator to notify the department in advance of each change in location. The department may require a separate permit fee for operations at each location.
(f) Every permit issued pursuant to the operating permit program shall:
(i) Be issued for a fixed term of five (5) years unless the department makes a finding, after public comment and hearing, and based on substantial evidence in the record, that an operating permit term of less than five (5) years is necessary to protect the public health and the environment except that operating permits to any affected source as defined in section 501 of the Clean Air Act shall be issued for no less and no more than five (5) years;
(ii) Be subject to termination, modification, revocation or reissuance for cause;
(iii) Allow for operational flexibility at the permitted facility without revising the permit; and
(iv) Be subject to revision by the department to incorporate applicable requirements under the Clean Air Act and this article which are promulgated after the permit is issued if the remaining term of the permit is for a term of three (3) or more years. Any revision required by this paragraph shall be acted on by the department within the time limits provided in W.S. 35-11-205(a).
