Dear Sir or Madam:

Public Workshop to Discuss the Proposed RACT/BARCT Determination
Stationary Spark-Ignited Internal Combustion Engines

The Air Resources Board (ARB or Board) staff will hold an informal public workshop to discuss the Reasonably Available Control Technology (RACT) and Best Available Retrofit Control Technology (BARCT) determination for stationary spark-ignited internal combustion engines. The RACT/BARCT determination focuses on reducing oxides of nitrogen (NOx), carbon monoxide (CO), and volatile organic compound (VOC) emissions from stationary engines powered by natural gas, waste and digester gases, and gasoline. This is a non-regulatory approach to assist all California districts in determining minimum emission standards for this source category. The proposal presents the basis for the determination, an overview of the control technology, the recommended emission standards, and a discussion of cost-effectiveness.

ARB staff will make a short presentation at the workshop, with most of the time open to hear comments, answer questions, and discuss the proposal. The date, time, and location of the workshop is:

Tuesday August 29, 2000
11:00 a.m. - 1:00 p.m.
Board Hearing Room
2020 L Street
Sacramento, California
