As of late January 2008 two new regulatory developments are worthy of mention:
1. The SOON program in SCAQMD (the LA basin covering most of LA, OC, Riverside, San Bernardino counties) and San Joaquin AQMD will NOT be mandatory for fleets over 20,000 hp during 2008. The entire program is up in the air (pun intended). This decision appears to have come from CARB staff and we are not certain what involvement the ARB Board has in this decision.
2. The 2007 Moyer funding had usually required adding VDECS on Tier 3 repowers. However, very recently we learn that these VDECS are being exempted, because they have been found not to work as intended.
