The Environmental Protection Agency (EPA) is approving revisions to the State Implementation Plan (SIP) for the state of Iowa.

EPA is also approving revisions to the Iowa Title V Operating Permits Program to revise the definition of "EPA Reference Method," and to adopt by reference the revised Title V Periodic Monitoring Guidance.
