Update Agency guidance on practical enforceability to more clearly describe how the technical accuracy of a permit limit should be supported and documented. In updating such guidance, the Office of Air and Radiation should consult and collaborate with the Office of Enforcement and Compliance Assurance, the Office of General Counsel, and the EPA regions.
21-P-0175_2	No	$0	$0
In consultation with the EPA regions, develop and implement an oversight plan to include: (a) an initial review of a sample of synthetic-minor-source permits in different industries that are issued by state, local, and tribal agencies to assess whether the permits adhere to EPA guidance on practical enforceability, including limits that are technically accurate, have appropriate time periods, and include sufficient monitoring, record-keeping, and reporting requirements; (b) a periodic review of a sample of synthetic- minor-source permits to occur, at a minimum, once every five years; and (c)procedures to resolve any permitting deficiencies identified during the initial and periodic reviews.
21-P-0175_3	No	$0	$0
Assess recent EPA studies of enclosed combustion device performance and compliance monitoring and other relevant information during the next statutorily required review of 40 C.F.R Part 60 Subparts OOOO and OOOOa to determine whether revisions are needed to monitoring, record-keeping, and reporting requirements for enclosed combustion devices to assure continuous compliance with associatedlimits, and revise the regulatory requirements as appropriate.

Revise the Agency’s guidance to communicate its key expectations for synthetic-minor-source permitting to state and local agencies.
21-P-0175_5	No	$0	$0
Identify all state, local, and tribal agencies in which Clean Air Act permit program implementation fails to adhere to the public participation requirements for synthetic-minor-source permit issuance and take appropriate steps to assure the identified states adhere to the public participation requirements.
