Specific Authorities Retained By EPA

In general, EPA does not delegate to state or local agencies the authority to make decisions that are likely to be nationally significant, or alter the stringency of the underlying standards.

As additional assurance of national consistency, state and local agencies must send to EPA Region 9 Air Division’s Enforcement Office Chief a copy of any written decisions made pursuant to the following delegated authorities:

Applicability determinations that state a source is not subject to a rule or requirement;
Approvals or determination of construction, reconstruction or modification;
Minor or intermediate site-specific changes to test methods or monitoring requirements; or
Site-specific changes or waivers of performance testing requirements.
