    Dear Ms. Gunn:
    Please find enclosed our review of Docket R04-3, SDWA Update, USEPA Regulations
    (January
    1, 2003 through June 30,
    2003
    ),

    for Public Comment.
    The sections reviewed in
    this docket include; 1412(b), 1414(c),
    1417(a), and
    1445(a)
    of

    Office of Regional Counsel
    Our comments,
    which are
    suggested changes,
    are as follows:
    1.
    A large number of the corrective amendments proposed by the IPCB relate to its
    deletion of section 611.130(a)
    (relief from the TTHM Rule) as obsolete.
    I raise
    this only to confirm that indeed this provision ofthe illinois rule is obsolete.
    2.
    Section 611.11 (a)(3)(A):
    the insertion ofthe language “may not be used” appears
    redundant, as the sentence previously states
    “
    a supplier may no longer employ
    ana1ytic~1.methodsusing the ICP-AES technology...”
    3.
    Section 611 .742(a)(6):
    the second “greater than or equal to” should be underlined
    (to indicate insertion), not crossed out to indicate deletion.
    4.
    Section 611
    Appendix F 4:
    Reference should be to section 611
    Appendix G
