Any such proposal will likely be cost-effective on a PM control basis only. Some control options reduce both VOC and PM for the same cost. The 1999 Amendments to the 1997 Ozone State Implementation Plan for the South Coast Air Basin makes specific emission reduction commitments for the year 2000. The amendment allows substitution of emission reductions when another rule results in more emission reductions than planned. These reductions will be achieved by rules adopted this calendar year.
Staff recommends continuing development of technologies.
A subsequent Board letter may request funding for additional tests of promising control equipment. Staff will return to the Board with a proposed rule early next year as cost-effective controls are finalized.
