Environmental Permit Applications
PacifiCorp's thermal generation facilities periodically submit air permit applications to state environmental agencies for a variety of reasons. To facilitate the dissemination of this information to the interested stakeholders and the general public, permit applications are posted on this site at least until the agency takes final action on the application.
