Utah Admin. Code R307-328-8 - Alternate Methods of Control

(1) Any person may apply to the director for approval of an alternate test method, an alternate method of control, an alternate compliance period, an alternate emission limit, or an alternate monitoring schedule. The application must include a demonstration that the proposed alternate produces an equal or greater air quality benefit than that required by Rule R307-328, or that the alternate test method is equivalent to that required by Rule R307-328. The director shall obtain concurrence from EPA when approving an alternate test method, an alternate method of control, an alternate compliance period, an alternate emission limit, or an alternate monitoring schedule.

(2) Manufacturer's operational specifications, records, and testing of any control system shall use the applicable EPA Reference Methods of 40 CFR Part 60 or other E PA -approved methods, to determine the efficiency of the control device. In addition, the owner or operator must meet the applicable requirements of record keeping for any control device. A record of all tests, monitoring, and inspections required by Rule R307-328 shall be maintained by the owner or operator for a minimum of two years and shall be made available to the director or the director's representative upon request. Any malfunctioning control device shall be repaired within 15 calendar days after it is found by the owner or operator to be malfunctioning unless otherwise approved by the director.

(3) For purposes of determining compliance with emission limits, volatile organic compounds and nitrogen oxides will be measured by the test methods identified in federal regulations or approved by the director. Where such a method also inadvertently measures compounds with negligible photochemical reactivity, an owner or operator may exclude these negligibly reactive compounds when determining compliance with an emissions standard.
