Control of Air Pollution; Removal and Modification of Obsolete, Superfluous or Burdensome Rules

The Environmental Protection Agency (EPA) is determining, through ``direct final'' procedure, that certain rules in the Code of Federal Regulations (CFR), 40 CFR Parts 51 and 52 should be deleted or modified. Deleting or modifying these rules will clarify their legal status and remove unnecessary, obsolete or burdensome regulations. In the proposed rules section of this Federal Register, EPA is proposing these determinations and soliciting public comment on them. If adverse comments are received on the direct final rule, EPA will withdraw the portions of the final rule that triggered the comments. EPA will address those comments in a final rule on the related proposed rule, which is being published in the proposed rules section of this Federal Register. See, for example, EPA's partial withdrawal of a direct final rule in 60 FR 6030 (Feb. 1, 1995). Any portions of the final rule for which no adverse or critical comment is received will become final after the designated period.
