## Abstract

The EPA is approving the Louisiana emission reduction credit (ERC) banking program as a revision to the Louisiana State Implementation Plan (SIP). The ERC banking regulation establishes a means of enabling stationary sources to identify and preserve or acquire emission reductions for New Source Review (NSR) emission offsets. The revisions remove the requirement that ERCs in the bank be set aside as a contingency measure for the attainment demonstration. The revisions also remove the requirement that NSR netting be conducted with surplus ERCs from the bank. The revisions clarify the requirement that ERCs be surplus to all requirements of the Clean Air Act (the Act) when used. The EPA approves these revisions to the ERC banking regulation to satisfy the provisions of the Act which relate to the permitting of new and modified sources which are located in nonattainment areas. The EPA does not approve the revisions as an Economic Incentive Program (EIP), nor through this rule alone are we allowing the use of ERCs for inter-precursor trading purposes or for alternate Reasonably Available Control Technology (RACT) compliance purposes. Pursuant to section 553(d) of the Administrative Procedure Act, EPA finds good cause to make this action effective immediately.
