Five-year progress report and other revisions to the State Implementation Plan
DEQ primary propose of this rulemaking is to incorporate the Regional Haze Plan: 5-year Progress Report into the Oregon State Implementation Plan. Under EPA’s federal Regional Haze Rule, states are required to adopt regional haze plans and provide reports evaluating its progress towards the goals to improve visibility in Class I areas over the next 60 years. The EQC adopted the first regional haze plan for Oregon in 2009. This proposed progress report fulfills the Regional Haze Rule requirement to provide a 5-year progress report update. The progress report summarizes changes in monitoring and emissions data and evaluates the adequacy of the current State Implementation Plan to meet the progress goals.
DEQ also proposes separate rule revisions as minor housekeeping fixes to the State Implementation Plan.
DEQ proposes changes to OAR 340, division number 200, 202 and 222 that will remove rules from the SIP that were accidentally submitted as SIP revisions.
