Narrative Summary of New Rule or Rule Changes: ( ) New Rule (X) Amended Rule

The following summarizes essential changes.

Subdivision (i) was modified to address potential impacts and/or violations of criteria pollutant air quality standards,

where Mobile Source Emission Reduction Credits (MSERCs) are used as an alternative method of compliance with

Regulation Xl rules with future compliance dates, as well as other District rules that allow the use of credits as permitted

in subparagraph (i)(1)(F). These modifications add language specifying the following requirements for use of MSERCs.

1. Paragraph(i)(3): an entity shall demonstrate to the Executive Officer that emissions at the entity’s facility are

not subject to Risk Reduction Requirements or the use of MSERCs will not result in adverse change in

attainment of risk redUction requirements under Rule 1402.

2. Subparagraph (i)(4)(A): establish that the use of MSERCs does not result in NOx emissions greater than or

equal to 200 pounds per day from those portable internal combustion engines as defined in paragraph (a)(5) of

Rule 1110.2, or NOx emissions from those portable internal combustion engines will not cause an exceedance

of the state nitrogen dioxide ambient air quality standard.

3. Clause (i)(4)(B)(i): demonstrate that the use of MSERCs will not result in causing an increase or forgoing a

reduction in carcinogenic health risk greater than I x i0~ or Hazard Index greater than I for all substances

listed in Rule 1402, and the assessment in health risk shall be conducted in accordance with guidance used in

implementing Rules 1401 and 1402.

4. Clause (i)(4)(B)(ii): demonstrate that the use of MSERCs will not result in a facility-wide Significant Risk Level

in accordance with Rule 1402 paragraph (d)(11).

5. Clause (i)(4)(B)(iii): demonstrate that the use of MSERCs will not cause a significant increase in an air quality

concentration as determined in Rule 1303.

Paragraph (i)(5) was added to clarify the implementation date for the foregoing revisions in subdivision (I). Specifically,

it requires that compliance plans currently being implemented (as of May 9, 1997) shall demonstrate compliance with

paragraphs (i)(3) and (i)(4) when their next plan is due or within six months of date of adoption, whichever occurs first.

regulations — including RECLAIM, Regulation Xl rules with future compliance dates, Regulation XX rules which allow

the use of credits, and Regulation XIII (New Source Review offsets).
