## Abstract

As part of the section 112(l), "Approval of State Programs and Delegation of Federal Authorities" rulemaking process, EPA (we) agreed to clarify which portions of the existing national emission standards for hazardous air pollutants (NESHAP) contain authorities that can be delegated to State, local, and tribal agencies (S/L/Ts) (65 FR 55810, September 14, 2000). Today's rulemaking clarifies which parts of the existing NESHAP can be delegated to S/L/Ts by adding or modifying a section in each NESHAP to describe the authorities that can be delegated to S/L/Ts and those that must be retained by us. In addition, to further clarify which portions of the NESHAP are delegable, some NESHAP standards sections were slightly reorganized or rephrased to separate delegable from non-delegable authorities. These clarifications do not change any substantive NESHAP requirements for industrial sources.
