Are NOx reductions required under the waste hauler rule?
No. NOx reductions are not required. However, a PM filter / NOx catalyst combination has been verified for some 1993 through 2002 Cummins and International / Navistar on-road engines. NOx reductions in some cases may qualify for incentive funding through the Carl Moyer Program. Check with your local air district by looking at “District Contacts” under “Program Information” near the bottom of the ARB’s Carl Moyer Memorial Air Quality Standards Attainment Program web page.
