(1) Upon receipt of a report under section 25-7-1006 (6)(b) from the division, and after the division has made the report available to all significant source or source categories identified pursuant to section 25-7-1006, the commission shall give notice that it is to conduct a rulemaking hearing concerning the implementation of control strategies recommended in the report.
(2) In addition to other applicable rule-making provisions, the rule-making hearing shall be conducted:
In reasonable proximity to the affected class I federal area;
To allow sufficient time for comment and testimony by all interested persons; and(c) To allow reasonable discovery pursuant to section 24-4-103 (13) and (14), C.R.S.
(3) (a) The commission shall order by rule implementation within a reasonable time of a practical and cost-effective control strategy or strategies that will provide reasonable progress toward remedying the impairment, if the commission finds that:
The evidence in the record shows the existence of a significant impairment of an airquality related value in a class I federal area;
An identifiable source or source category is responsible for significantly causing orcontributing to the impairment;
The best available retrofit technology exists for any such stationary source;
Reasonably available control measures exist for any such other sources or sourcecategories;
Implementation of the control strategies would make significant improvement in theimpairment;
Taking into account that the ability to attribute the cause of air pollution effects andto apportion the air pollution effects among sources and source categories identified by attribution studies is an area of evolving science, a correlation of the extent of improvement in air quality related value impairment can reasonably be expected to result from imposition of a control strategy or strategies for each significant source or source category identified by the division.
(b) Within fourteen days after having received the division's report under section 25-71006 (6)(b), a source or source category may petition the commission, as part of its rule-making hearing conducted pursuant to this subsection (3), to make a determination that the benefits of phasing, segmenting, or excusing the control strategy or strategies outweigh the benefits of imposing the control strategy or strategies. In making such determination, the commission shall consider all economic and related costs associated with the implementation of the control strategy or strategies involving the source or source category. The burden of proof shall be on the petitioner.
