    SUMMARY: This document contains a clarification and corrections to the

    proposed rulemaking, the NSR Reform rulemaking, which was published 
    Tuesday, July 23, 1996 (61 FR 38249). The NSR Reform rulemaking 
    proposes to revise regulations for the approval and promulgation of 
    implementation plans, and the requirements for preparation, adoption, 
    and submittal of implementation plans governing the NSR programs 
    mandated by parts C and D of title I of the Clean Air Act.

    SUPPLEMENTARY INFORMATION:
    
    Clarification
    
        The EPA proposed the Clean Unit exclusion as a simplified 
    applicability test for changes to existing emissions units that already 
    are well controlled. See 61 FR 38255-38258. The proposal is intended to 
    require that in order for an existing emissions unit to qualify as a 
    ``clean unit'' the unit must have a federally enforceable emissions 
    limit that ``is comparable'' to the best available control technology 
    or lowest achievable control technology requirements for that type of 
    unit, whichever would otherwise be applicable to the proposed change. 
    The relevant regulatory language is contained in proposed 
    Sec. 51.165(a)(1)(v)(C) (10) through (13) of the nonattainment NSR 
    rules, Secs. 51.166(b)(2)(iii)(L) (1) through (4), and 
    52.21(b)(2)(iii)(L) (1) through (4) of the PSD rules, and is referenced 
    in Sec. 52.24(f) of the statutory restriction on new sources 
    (construction ban). In each rule, EPA intended that eligibility for the 
    clean unit exclusion is to be contingent upon several criteria being 
    satisfied. However, in the proposed language in Sec. 51.165 it may not 
    be clear to the reader that each of the criteria under paragraphs 
    (a)(1)(v)(C)(10) through (a)(1)(v)(C)(13) must be satisfied in order 
    for an emissions unit to qualify for the exclusion. Because of a 
    problem with the overall structure of the regulations at Sec. 51.165, 
    it is not feasible to make a simple correction without first 
    restructuring the overall regulation. Instead, for purposes of 
    interpreting and commenting on the proposal the reader is advised to 
    read the ``Clean Unit'' exemption as provided in 
    Secs. 51.166(b)(2)(iii)(L) (1) through (4) and 52.21(b)(2)(iii)(L) (1) 
    through (4) (as corrected below) for the correct interpretation of the 
    proposed exclusion. The EPA is considering the most effective way to 
    restructure Sec. 51.165 to correct the problem, and intends to make the 
    necessary restructuring at the time of promulgation of final 
    rulemaking.
    
    Need for Correction
    
        As published, the preamble and proposed amendments to the 
    regulations at Secs. 51.166 and 52.21, contain errors which are 
    misleading and are in need of clarification.
    
    Correction of Publication
    
        Accordingly, the publication on July 23, 1996 of the proposed 
    regulations 40 CFR 51.166 and 52.21, which were the subject of FR Doc. 
    96-17544, are corrected to read as follows:
    
    Correction to Preamble
    
        1. On page 38258, in the first column, in section II.C.4., 
    Description of the Clean Facility Proposal, in the third sentence, the 
    reference ``Secs. 51.165(a)(1)(v)(C)(11),'' is corrected to read 
    ``Secs. 51.165(a)(1)(v)(C)(14),''.
    
    
    Sec. 51.166  [Corrected]
    
        2. On page 38330, in the second column, in Sec. 51.166, paragraph 
    (b)(2)(iii)(L)(2)(iii), the last line is corrected by removing the 
    period (``.'') and adding a semicolon (``;'').
        3. On page 38330, in the second column, in Sec. 51.166, paragraph 
    (b)(2)(iii)(L)(3), the last line is corrected by adding the word 
    ``and'' after the semicolon.
        4. On page 38330, in the second column, in Sec. 51.166, paragraph 
    (b)(2)(iii)(L)(4), the last line is corrected by removing the text ``; 
    and'' and adding a period (``.'').
    
    
    Sec. 52.21  [Corrected]
    
        5. On page 38337, in the third column, in Sec. 52.21, paragraph 
    (b)(2)(iii)(L)(2)(iii), the last line is corrected by removing the 
    period (``.'') and adding a semicolon (``;'').
        6. On page 38337, in the third column, in Sec. 52.21, paragraph 
    (b)(2)(iii)(L)(3), the last line is corrected by adding the word 
    ``and'' after the semicolon.
        7. On page 38337, in the third column, in Sec. 52.21, in paragraph 
    (b)(2)(iii)(L)(4), the last line is corrected by removing the text ``; 
    and'' and adding a period (``.'').
