The Environmental Protection Agency is unlikely to grant a request by state air regulators to issue proposed implementation rules and guidance with an upcoming final decision on national ozone standards, the agency's top air official said. Janet McCabe, EPA acting assistant administrator for air and radiation, said it is "not going to be realistic" for the agency to release the supporting guidance and implemen- tation rules with the final ozone rule, which must be signed by Oct. 1. The agency has proposed to revise the current 75 parts per billion standard to somewhere in the range of 65 ppb to 70 ppb. McCabe said the EPA and states have gotten "a jump" on addressing implementation issues because the proposed rule to revise the ozone standards includes specific requests for comment on various issues.
