Which stationary source categories were evaluated for performance standards?
The districts prepared the initial CCAA plans in the early part of this decade. At that time, all the districts submitting a plan committed to adopting every feasible measure. To assist the districts in this effort, the ARB staff developed a list identifying feasible measures that districts could use in developing their clean air plans. This list identified source categories for which regulations were clearly available and effective and represented a starting point for each district’s analysis. It was provided with the expectation that, as regulatory programs moved forward and technology advanced, the every feasible measure list would undoubtedly change for each district.
