California Air Resources Board (CARB or Board) staff invites you to participate in a public workshop to update stakeholders on the development of the proposed amendments to CARB's ONMC regulations. This workshop is a follow-up to the ONMC workshop held November 2020 and will include the following topics:
a. Results of ONMC evaporative emissions research by CARB, U.S.EPA, and the Manufactureres of Emissions Controls Association (MECA)
b. Draft CARB ONMC diurnal evaporative standards and test procedures
c. Revisions to CARB staff’s regulatory proposal for ONMC presented Nov. 2020
• New proposed regulation effective dates
• In Use Verification Program (IUVP)
• On Board Diagnostics (OBD) requirements for Class 1A motorcycles
d. Updates to CARB staff’s regulatory development timeline
Further details regarding the workshop along with a more detailed agenda and other technical documents, will be posted prior to the workshop on the ONMC - Meetings & Workshops page.
The workshop meeting format will be held via Microsoft Teams webinar at the following date and time:
Date: Wednesday, January 12, 2022
Time: 9:00 a.m. – Noon (PST)
Location: Webinar/Teleconference
Background
In recent years, CARB has progressively lowered emission standards on new vehicles and engines, moving to zero or near zero levels in some categories. However, CARB has not proposed new standards for ONMC since 1998, causing the emissions impact from ONMC to grow disproportionately compared to other on-road categories. In addition, jurisdictions around the world have already adopted more stringent emissions standards for ONMCs to help control air pollution.
Recognizing that ONMC emissions can be lowered, and that additional reductions are needed to help California meet air quality goals, CARB staff kicked off the process for updating California’s ONMC emissions standards with a public workshop in 2018. Since then, there have been many technical working group meetings with a wide range of stakeholders leading to a draft regulatory proposal that CARB staff shared in a November 2020 workshop. The core of staff’s proposal allows for a large degree of harmonization with the more stringent Euro 5 exhaust standards, with additional requirements for new evaporative emissions controls and on-board diagnostics. The proposed regulation would also introduce new zero emissions motorcycle (ZEM) sales requirements and corresponding ZEM credit program. Following the November 2020 Workshop, CARB staff completed emissions testing and revised elements of the proposal to address comments from manufacturers. Staff is now ready to share revisions to the proposed regulatory concepts discussed at the November 2020 workshop and solicit additional feedback prior to issuing a formal regulatory proposal for public comment in Spring of 2022.
CARB staff invite interested members of the public to submit written comments on any potential regulatory proposals or the material presented at the workshop and ask that comments be submitted no later than February 1, 2022. Please note that under the California Public Records Act (Government Code section 6250 et seq.), your written and verbal comments, attachments, and associated contact information (e.g., your address, phone, email, etc.) become part of the public record and can be released to the public upon request.
