2025 Interim Final Rule to Extend Compliance Deadlines

Frequently Asked Questions

How does the July 2025 interim final rule impact my compliance requirements?

The July 2025 interim final rule extended several compliance deadlines from the 2024 final rule. The reporting deadlines associated with these compliance deadlines were also extended as a practical matter. We note that in this interim final rule, we are extending compliance deadlines in the 2024 NSPS as follows:

  • The deadline to meet certain requirements related to control devices, equipment leaks, storage vessels, process controllers, and covers/closed vent systems will be extended to 18 months after the interim final rule is published in the Federal Register. 
    • This includes extending the deadline to require that flares and enclosed combustion devices used to control emissions have a continuous pilot flame and for an alarm to be sent to the nearest control room if the pilot or combustion flame is not lit.
