EPA conditionally approved Rule 335-3-8-.72, NOX Budget Program Monitoring and Reporting, submitted by Alabama on February 27, 2020, into the Alabama SIP on July 7, 2021. This conditional approval is based on Alabama's September 15, 2020, commitment to the EPA to correct, within one year of the conditional approval, the stack testing requirement, which was added to Rule 335-3-8-.72(1)(c) in error. If Alabama fails to meet its commitment by July 7, 2022, the conditional approval will become a disapproval on July 7, 2022 and EPA will issue a notification to that effect.
