TITLES 13 and 17. CALIFORNIA AIR RESOURCES BOARD

By notice dated October 19, 2010, and published in the October 29, 2010, California Regulatory Notice Register, Register 2010, No. 44-Z , the Air Resources Board (ARB or Board) provided Notice of Public Hearing to Consider the Adoption of Proposed Amendments to the Regulation to Reduce Emissions of Diesel Particulate Matter, Oxides of Nitrogen and other Criteria Pollutants fr om In-Use On-Road Diesel-Fueled Vehicles, The Heavy-Duty Vehicle Gree nhouse Gas Emission Reduction Measure and the Regulation to Control Emissions fro m In-Use On-Road Diesel-Fueled Heavy-Duty Drayage Trucks at Ports and Intermodal R ail Yard Facilities.

PLEASE BE ADVISED there was an error in the notice regarding ARB hea ring date for this rulemaking. The following date appears in the first paragraph on page 3 of the

notice:

December 16 and 17, 2020

The date was corrected to read as follows:

December 16 and 17, 2010

PLEASE BE FURTHER ADVISED that the Staff Report: Initial Statement of Reason s (ISOR) prepared by staff inadvertently omitted a co nsidered alternative to the Truck and Bus regulation that would exempt school buses from the regulation unless full funding for replacements was provided. That alternative sh ould have been discussed on page 69 of the ISOR, at section VIII.A.4. The omitted a lternative reads:



### 4. Exempt School Buses Unless Full Funding for Repl acements is

Provided

Staff evaluated the feasibility to exempt school bu ses unless funding for replacements is provided. Staff rejected this proposal for the fol lowing reasons:

• As studies have shown, providing cleaner air to on e of the most sensitive populations, California’s children, continues to be a high priority that must be accomplished without delays.

• Furthermore, the cost associated with replacing al l remaining non-compliant vehicle could be as high as $1.1 Billion, while allowing sc hool districts the current flexibility of retrofitting or replacing school buses is estima ted to cost only $60.1 Million.

• Retrofitting school buses continues to be a more c ost-effective emission reduction strategy than replacements.2

Staff recognizes the current fiscal difficulties sc hools are facing and is committed to working with the school districts to obtain additio nal funding to help reduce emissions

associated with school buses.

PLEASE BE FURTHER ADVISED that Appendix J to the ISOR, “Methodology for Estimating Ambient Concentrations of Particulate Ma tter from Diesel-Fueled Engine

Emissions” and “Health Benefits Associated with Red uctions in Diesel PM Emissions from In-Use On-Road Heavy-Duty Diesel-Fueled Vehicl es,” has been modified to incorporate minor edits.

• Pages J-19 and J-24, staff inadvertently cited to Fotheringham and Rogerson as the authors of the article upon which staff relied on p age J-19; the reference to Fotheringham and Rogerson has been deleted and repl aced with Flowerdew and Green, 1994; the reference to Fotheringham and Rog erson on page J-24 has been

modified to reflect that Flowerdew and Green were t he authors of the article relied upon and that Fotheringham and Rogerson were the ed itors of the book in which the article appeared.

• Pages J-22 and J-24, staff inadvertently cited to Cran on page J-22; the citation and the reference on page J-24 have been deleted;

• Pages J-24 and J-25, staff added specific file nam es to a number of references to assist readers in locating the files on the identif ied Internet websites.

The complete text of the notice, the Initial Statem ent of Reasons, including Appendix J, and all subsequent regulatory documents are availab le on ARB’s website for this rulemaking at: http://www.arb.ca.gov/regact/2010/truckbus10/truckb us10.htm
