ERRATA 

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 from In-Use On-Road 

Diesel-Fueled Vehicles, The Heavy-Duty Vehicle Greenhouse Gas Emission Reduction 

Measure and the Regulation to Control Emissions from In-Use On-Road Diesel-Fueled 

Heavy-Duty Drayage Trucks at Ports and Intermodal Rail Yard Facilities. 

PLEASE BE ADVISED there was an error in the notice regarding ARB hearing 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 Reasons 

(ISOR) prepared by staff inadvertently omitted a considered alternative to the Truck and 

Bus regulation that would exempt school buses from the regulation unless full funding 

for replacements was provided. That alternative should have been discussed on page 

69 of the ISOR, at section VIII.A.4. The omitted alternative reads: 

4. Exempt School Buses Unless Full Funding for Replacements is 

Provided 

Staff evaluated the feasibility to exempt school buses unless funding for replacements is 

provided. Staff rejected this proposal for the following reasons: 

• As studies have shown, providing cleaner air to one 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 all remaining non-compliant vehicle 

could be as high as $1.1 Billion, while allowing school districts the current flexibility 

of retrofitting or replacing school buses is estimated to cost only $60.1 Million. 

• Retrofitting school buses continues to be a more cost-effective emission reduction 

strategy than replacements.

Staff recognizes the current fiscal difficulties schools are facing and is committed to 

working with the school districts to obtain additional 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 Matter from Diesel-Fueled Engine 

Emissions” and “Health Benefits Associated with Reductions in Diesel PM Emissions 

from In-Use On-Road Heavy-Duty Diesel-Fueled Vehicles,” 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 page J-19; the reference to 

Fotheringham and Rogerson has been deleted and replaced with Flowerdew and 

Green, 1994; the reference to Fotheringham and Rogerson on page J-24 has been 

modified to reflect that Flowerdew and Green were the authors of the article relied 

upon and that Fotheringham and Rogerson were the editors 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 names to a number of references to 

assist readers in locating the files on the identified Internet websites. 

 

The complete text of the notice, the Initial Statement of Reasons, including Appendix J, 

and all subsequent regulatory documents are available on ARB’s website for this 

rulemaking at: http://www.arb.ca.gov/regact/2010/truckbus10/truckbus10.htm

 

Any questions regarding these corrections should be directed to Lori Andreoni, 

Manager, Board Administration & Regulatory Coordination Unit at (916) 322-4011 or 

Trini Balcazar, Regulations Coordinator at (916) 445-9564.
