Cummins West offers an array of products and packages that are compliant with:

  • State and local noise and emission requirements
  • IBC/CBC 2006 seismic requirements
  • OSHPD Requirements – Cummins West offers a full line of OSHPD pre-approved gensets, automatic transfer switches and paralleling systems. Visit our OSHPD Solutions Homepage to see more information on our OSHPD pre-approved portfolio.

2012 Stationary Generator Emissions Update

1) With modification to the ATCM in 2011, emergency standby generators must meet EPA regulations, hence T4i emission levels are not required by CARB. Local air districts, however, may enforce more stringent emission regulations as they see fit. Usually, this is done on a case by case basis, based on a risk screen analysis when a permit is secured.

2) In late 2011 The BAAQMD mailed out a compliance advisory to owners and operators of stationary IC engines. The subject line reads "New Emission Limits for Stationary IC Engines (Reg 9, Rule 8) and CARB ATCM's for Diesel Engines". This advisory outlines new NOx limits which go into effect on 1/1/2012. That said, page two of the advisory states that emergency engines are exempt from these new emission requirements. A link to the website with the advisory can be found at: BAAQMD Advisory

3) All new prime power stationary generators in California are subject to both CARB's ATCM and EPA's T4i emission requirements. Aftertreatment will be included on all prime power proposals.
