Air Quality State Implementation Plans; Approvals and Promulgations: Excess Emissions during Periods of Startup, Shutdown, and Malfunction; Partial Withdrawals of Findings of Failure
Summary
This EPA regulation adjusts rules about air pollution from factories and power plants during startup, shutdown, and equipment problems. It gives states more flexibility in how they manage these temporary emissions to meet clean air standards.
Key Points
- 1The EPA is withdrawing some previous findings that certain states failed to adequately control air pollution during plant startups and shutdowns
- 2States can now update their air quality plans with more realistic allowances for temporary pollution spikes when equipment starts up, shuts down, or malfunctions
- 3This affects industrial facilities like power plants, refineries, and manufacturing plants that need to account for unavoidable emissions during these operational changes
- 4States must still work toward meeting federal air quality standards overall, but have clearer rules for handling temporary excess emissions
- 5The regulation gives states until the deadline to submit updated air quality plans reflecting these new guidelines
Impact Assessment
If you are a manufacturer or power plant operator, this means you have more flexibility in how you report and manage temporary air pollution during equipment startup, shutdown, and breakdowns.
