Annual Emissions Inventory | Proposed Air Quality Rulemaking
ADEQ welcomes comments on the proposed rulemaking to amend Arizona Administrative Code (AAC) R18-2-327 Annual Emissions Inventory Questionnaire.
Summary:
The purpose of this rulemaking is to amend the agency's annual emission inventory questionnaire regulation to reduce the reporting burden on Class II air quality permitted sources. ADEQ proposes to amend the reporting frequency from annually to at least once every three years and at the request of the Director.
In addition, ADEQ is proposing to amend the agency's annual emission inventory questionnaire regulation to include federally required emission statement requirements for stationary sources located in ozone nonattainment areas that emit ozone precursors. This rulemaking action is required to secure full approval of Arizona’s ozone rules into the state implementation plan (SIP) and avoid sanctions under the federal Clean Air Act (CAA).
