I. GENERAL INFORMATION District: South CoastAQMD Rule No: 1610 Date Amended: April 11. 1997 Rule Title: Old-Vehicle Scrapping Date Submitted to ARB: April 29. 1997 Ifan Amended Rule, Dated Adopted: January 8. 1993 Isthe Rule Intended to be Sent to the U.S. EPA as a SIP Revision (X) Yes 

### ( ) No If NO, do notcomplete remainderofform. District Contact: Henry Hogo Phone Number: (909) 396-3184 Narrative Summary of New Rule or Rule Changes: 

### ( ) New Rule (X) Amended Rule The following summarizes essential changes. 1. Paragraph(b)(1), the definition of Mobile Source Emission Reduction Credit (MSERC), was modified to make clear and explicit that MSERCs are based on emission reductions that are surplus to ARB, 

### District, and U.S.EPA regulations, as well as the most recent District- or U.S.EPA-approved Air Quality Management Plans, whicheveris more stringent. 2. Paragraph (h)(5) and subparagraph (l)(2)(E) were modified to allowforfederal enforceability ofthe rule: (1) by requiring emission quantification methodology updates to be incorporated into a rule revision approved by the District Governing Board and submitted to the U.S.EPA for inclusion into the State Implementation Plan; and (2) by requiring that District Governing Board-approved emission quantification methodologies (as contained in the stationary source rule permitted to use MSERCs as an alternative method of compliance) be used to quantify stationary source emission impacts, and requiring that the Executive Officer submit the specific stationary source rule that contains the quantification methodology to U.S.EPA for inclusion into the State Implementation Plan. 3. Paragraphs (k)(5) and (l)(8) were modified to explicate that the Executive Officer shall store all compliance records submitted by the AQMD-licensed scrappers, and specifies that it be for a minimum of five years (consistent with the five-year life of the MSERCs). Other minor clarifications are also made to the record retention time in the recordkeeping requirements ofsubdivision (j). 4. Subdivision (a) was modified to clarify the existing intent ofthe rule. Language was also added to prohibit the use of MSERCs toward compliance with federal requirements, including those promulgated by U.S.EPA as authorized underTitle 42, Sections 7411 and 7412(d), and 7511 b ofthe U.S. Code where the regulations do not authorize compliance through emissions trading.
