Reasons Supporting Proposal: See list above.


•	Clarify and update the construction permitting (new source review) program regulations to reduce regulatory burden and focus on permitting projects where our permits provide significant air quality benefit (NWCAA Sections 300-305).
•	Modify the registration program to improve transparency and equity (NWCAA Sections 320-321).
•	Remove the ambient air quality standards from the regulation in favor of the state rule that already applies statewide (NWCAA Sections 400-428).
•	Clarify and update the sulfur dioxide requirements (monitoring, etc.) at certain sources to include only those requirements that add air quality benefit in the current conditions (NWCAA Section 460).
•	Modify a few definitions to clarify applicability and to match the state rule (NWCAA Section 200).
•	Update the adoption-by-reference date to allow us to implement the most recent version of the referenced state and federal rules (NWCAA Section 104).
