What will be included in regional implementation plans?

The regional implementation plans are expected to be consistent with the Agency‐wide guidelines finalized in EPA Actions. First, the Plans will address with more specificity the process that a regional office will use to prioritize permits for enhanced outreach. This includes outlining whether the regional office will use a screening tool or other methodology to help identify overburdened communities and the types of permits with significant public health or environmental impacts that the regional office will consider prioritizing for enhanced engagement. Second, the regional implementation plans will include a list of the activities that the regional office will undertake at key junctures in the permitting process to enhance the engagement of overburdened communities. We expect that all plans will share basic elements but may also vary as the permitting offices adapt them to address their particular needs.
