49-491. Conditional orders; standards; rules

A. The director may grant to any person a conditional order for each air pollution source which allows such person to vary from any provision of this article, any rule adopted pursuant to this article, or any requirement of a permit issued pursuant to this article if the control officer makes each of the following findings:

1. Issuance of the conditional order will not endanger public health or the environment, or impede attainment of the national ambient air quality standards.

2. Either of the following is true:

(a) There has been a breakdown of equipment or upset of operations beyond the control of the petitioner; the source was in compliance before the breakdown or upset; and the breakdown or upset may be corrected within a reasonable time.

(b) There is no reasonable relationship between the economic and social cost of, and benefits to be obtained from, achieving compliance.

B. The board of supervisors shall adopt rules necessary for the issuance of conditional orders. Such rules shall specify the minimum requirements for petitions, and procedures for processing petitions and for public participation. For a conditional order that would vary from a requirement of the state implementation plan, the rules adopted by the board of supervisors shall provide for a public hearing to receive comments on the petition. For a conditional order that would vary from a requirement of a permit issued pursuant to this article, the rules adopted by the board of supervisors shall conform to the procedures established for permit revisions pursuant to section 49-480.01.
