NTAA: Policy Response Kits

Policy Response Kits:


Regional Haze Rule Revisions

On May 4, 2016, the United States Environmental Protection Agency (US EPA) proposed regulatory revisions to the Regional Haze Rule’s visibility protection requirements that states must adhere to when submitting state implementation plans (SIPs) and progress reports for regional haze. Periodic regional haze SIPs are required by the Clean Air Act (CAA) and federal rules in order to provide for reasonable progress towards restoration of natural visibility conditions in national parks, wilderness areas, and other mandatory designated Class I areas. This requirement does not apply to areas that states or Tribes have designated as “non-mandatory” Class I areas.

NTAA has prepared a Policy Response Kit for Tribes to use for submitting comments to EPA by August 10th. The Policy Response Kit includes NTAA comments to EPA submitted on June 22nd, 2016, a template letter for Tribes to use in submitting comments to EPA and a fact sheet Tribal staff and use to inform Tribal leaders about this issue.

2015 Comments on Regional Haze Rule Revisions

In 2015, NTAA submitted early comments to EPA in response to EPA’s request for comments for Tracking Visibility Progress in the Regional Haze Rule that focus on the Reasonable Progress Framework on Controllable Emissions that contribute to Regional Haze. In addition, comments were submitted by NTAA regarding the proposed delay of the current state implementation plan (SIP) submission deadlines, the timing and format of progress reports, limiting requirements for reasonably attributable visibility impairment (RAVI) while expanding the number of states that would be subject to Federal Land Management (FLM) RAVI certifications, and consultation with Indian Tribes concerning the RHR and associated activities. EPA will be drafting a guidance document in the coming months and issue that guidance document for further review in the new year.
