EPA proposes changes to Wyoming regional haze plan for Dave Johnston power plant
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
The proposal would change federal air-quality requirements for nitrogen oxide emissions at PacifiCorp’s Dave Johnston Power Plant Unit 3 in Wyoming. The EPA would remove a previous requirement tied to closing the unit, after PacifiCorp withdrew its consent to that closure. The EPA is also proposing to revise the plant’s pollution-control standard using newer information that was not available when the federal plan was issued in 2014. PacifiCorp, Wyoming air-quality regulators, environmental groups, nearby communities, and other power-sector stakeholders may want to comment before the deadline.
