Proposed revisions to the EPA’s Regional Haze Rule (RHR) were published in the Federal Register on May 4, 2016 according to this June 30, 2016 Trinity Consultants report. This proposed rule directly impacts state, local, and tribal governments as well as Federal Land Managers (FLMs) responsible for protection of visibility in Class I areas.
The 1977 Amendments to the Clean Air Act (CAA) set a national goal to restore the 156 federally mandated Class I Areas, including national parks and wilderness areas, to pristine conditions by preventing any future, and remedying any existing, man-made visibility impairment, or “regional haze.”
Indirectly, this rule may potentially affect sources that emit visibility-impairing pollutants, including particulate matter less than or equal to 10 and 2.5 microns in diameter (PM10/PM2.5), sulfur dioxide (SO2), nitrogen oxides (NOX), and volatile organic compounds (VOC).
- The May 4, 2016 proposed amendments address requirements for the second planning period (2018 – 2028) with several proposed updates.
Rolling back the due date for SIPs for the second implementation period to July 31, 2021; the end date will remain 2028, meaning SIPs will still focus on measures to achieve reasonable progress by 2028.
- Removing the requirement that progress reports be submitted as SIP revisions, but adding the requirement for states to consult with FLMs and obtain public comment on their progress reports prior to submitting to EPA.
- Changing the due dates for progress reports per state to a fixed schedule. The second and all subsequent progress reports would be due by January 31, 2025; July 31, 2033; and every 10 years thereafter.
- Revising the way in which some days are being selected for purposes of tracking progress towards natural visibility conditions in order to focus on anthropogenic emissions and provide the option to exclude emissions from natural events (e.g., fires).
- Adding the requirement that all states (not just those with Class I areas) develop long-term strategies using the four statutory factors to ensure reasonable progress.
What this means to you
EPA is proposing changes to its Regional Haze Rule that may affect sources that emit visibility-impairing pollutants, including particulate matter less than or equal to 10 and 2.5 microns in diameter (PM10/PM2.5), sulfur dioxide (SO2), nitrogen oxides (NOX), and volatile organic compounds (VOC).
