Meetings for Small Off-Road Engines

This page last reviewed September 25, 2008

• April 21, 2008 - ARB hosted a public workshop to discuss proposed amendments to the California regulations and test procedure for small off-road engines (SORE) and large spark-ignition engines with an engine displacement less than or equal to one liter (LSI ≤ 1 L).  Specifically, the discussion will focus on standards for LSI ≤ 1 L, modifications to the SORE emissions credit program, and other minor changes to the regulatory language.  This is the second workshop in continuation of the rulemaking process.  The proposed regulations are scheduled to be presented to the Board at the November 20-21, 2008 hearing. (Note:  Board Hearing date change)
