Arkansas SIP History

ARKANSAS SIP HISTORY

The status of each State SIP is given in Title 40, Part 52, of the U.S. Code of Federal Regulations (40 CFR Part 52).  The status of the Arkansas SIP is given in 40 CFR Part 52, Subpart E, Sections 52.170 to 52.200.  The first section in the subpart for each state is the “Identification of plan” section.  The Identification of plan for Arkansas is in Section 52.170.

Until October 23, 1998, the Arkansas Identification of plan in Section 52.170 was used to give a chronological development of the Arkansas SIP.  The table below gives the Federal Register date and page number and effective date when each paragraph of the Arkansas Identification of plan was added or revised.  The numbers in the left column are the current paragraph numbers.  Some paragraphs were added as a different number and later changed to the number listed.  Only Federal Register rulemaking actions revising the Arkansas Identification of plan are listed.  The current text of each paragraph listed is in Section 52.200 in the July 1, 1999 and later editions of Part 52, and in Section 52.170 in the July 1, 1998 and earlier editions of Part 52.  Other sections in Subpart E have their own Federal Register citations.
On October 23, 1998 (63 FR 56824 to 56830), EPA moved the Arkansas Identification-of-plan paragraphs in 52.170 to new 52.200 and replaced the paragraphs in 52.170 with a list of elements in Arkansas SIP.  The purpose of this action was to start using the Arkansas Identification of plan section to more clearly identify the provisions that constitute the enforceable elements of the Arkansas SIP.  In the list below, the titles of the rule-making actions are given in the left column for the October 23, 1998, Federal Register action, and all subsequent Arkansas SIP Federal Register rule-making actions.
In the table below, the "ARd*" numbers preceding the titles of Federal Register actions published since October 23, 1998, are unofficial numbers used by EPA Region 6 to assist in tracking the direct final rule and final rule actions approving revisions to the Texas SIP.
Federal Register actions in the table below published since April 2007 that have a Regulations.gov ID number have a docket in the Federal Government Regulations.gov web site which contains documents related to the Federal Register action.  "ARaaa" numbers following "ARd" numbers in the titles of the Federal Register actions in the table are EPA Region 6 numbers assigned to each Region 6 Regulations.gov docket.  The docket title and the titles of all documents within the docket begin with the number.

Footnotes:

(2)   SIP Effective Date Note:  Before about 1980, SIP Federal Register rule-making actions did not have effective date sections.  For those actions, it is assumed in this table that the effective date is the date published.
Most Federal Registers published since April 2007 are available in the respective Regulations.gov dockets.
