Title V Operating Permit Part 70 Program Approvals

Alaska

Idaho

Oregon

Washington


Construction Permit Program Approvals

All state and local construction permit programs (with one limited exception in the state of Washington) have been approved through the State Implementation Plan (SIP) approval process.

In Washington, EPA retains a limited Federal Implementation Plan (FIP) under 40 CFR 52.21 and issues partial PSD permits to ensure that major sources have a means to satisfy the Clean Air Act construction permit requirements for greenhouse gases when CO2 emissions from the industrial combustion of biomass cannot be considered or regulated by either the Washington Department of Ecology (Ecology) or the Energy Facility Site Evaluation Council (EFSEC) under their PSD rules.

See 80 FR 23721 (PDF)(10 pp, 285 K) and 82 FR 24531 (PDF)(7 pp, 271 K) for further explanation of the PSD FIP in Washington as it relates to those facilities, emission sources, geographic areas, and permits under the otherwise full jurisdiction and authority of Ecology and EFSEC, respectively.
