§ 52.725 Control strategy: Particulates.
(a) [Reserved]
(b) Part D—Disapproval. (1) U.S. EPA disapproves the provisions of Rule 203(f) which allow the use of an equivalent method without review and approval of that method. Any source subject to Rule 203(f) which chooses to use an equivalent method must have that equivalent method submitted to U.S. EPA and approved as a SIP revision.
(2) U.S. EPA disapproves the following portions of Rule 203(d)(5) which regulate the control of particulate matter from specific sources within the iron and steel industry: Rule 205(d)(5)(B)(ii), Rule 205(d)(5)(B)(iii), Rule 205(d)(5)(D), and Rule 205(d)(5)(K).
(3) USEPA disapproves a proposed SIP revision submitted by the State on May 12, 1982, in the form of a May 18, 1981 Consent Decree (Civil Action 81-3009) to which USEPA, Illinois Environmental Protection Agency and National Steel Corporation are parties and a draft Alternative Control Strategy Permit. This submission was modified by the State, September 30, 1982, with the submission of a separate document embodying the elements of the Alternative Control Strategy. This separate document was intended to become an enforceable part of the SIP.
(c) Approval—On September 28, 1988, the State of Illinois submitted a committal SIP for particulate matter with an aerodynamic diameter equal to or less than 10 micrometers (PM10) for the Illinois Group II areas of concern in DuPage, Will, Rock Island, Macon, Randolph, and St. Clair Counties. The committal SIP contains all the requirements identified in the July 1, 1987, promulgation of the SIP requirements for PM10 at 52 FR 24681.
