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.
