District: South Coast AQMD Rule No: 1610 Date Amended: April 11. 1997

Rule Title: Old-Vehicle Scrapping

Date Submitted to ARB: April 29. 1997 If an Amended Rule, Dated Adopted: January 8. 1993

Is the Rule Intended to be Sent to the U.S. EPA as a SIP Revision (X) Yes ( ) No If NO, do not complete remainder of form.

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,

whichever is more stringent.

2. Paragraph (h)(5) and subparagraph (l)(2)(E) were modified to allow for federal enforceability of the 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 of subdivision (j).

4. Subdivision (a) was modified to clarify the existing intent of the 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 under Title 42, Sections 7411 and 7412(d), and 7511 b of the U.S. Code where the regulations do not

authorize compliance through emissions trading.
