“Hi Mark – We are not able to provide you with any certainty at this time but we can tell you where
we are in the process regarding evaluating any potential amendments to the stationary engine air
toxic control measure (ATCM). Staff has investigated the feasibility of requiring Tier IV for
emergency back up engines and at this point believe SCR is probably not cost-effective in most
situations provided the number of hours are typical of what was reported to the survey we
conducted during the development of the ATCM – about 22 hours of M&T and 6-8 hours of
emergency operation. However, there may be some situations, i.e. an emergency-back-up
engines that operates for many hours, where an SCR would provide air quality benefits. ARB
staff continues to believe DPFs are cost-effective and feasible for emergency back-up
operations but we are open to investigating if the requirement for DPFs should be limited to
certain situations such as when an engine is in a populated area, or close to sensitive
receptors. Please be aware, that these are only staff’s opinion - we haven’t briefed upper mgt.
or taken these ideas through the public process yet.
Regarding the timing for any amendments, we are on the Board calendar for the July 2010
hearing. Our first workshop is tentatively planned for March 1st and the notice should be going out
in the next week or two. We are also planning on conducting a short survey to collect updated
information on back-up engines and typical hours of operation. We are hoping to have this
distributed the first week in February.
I know this probably doesn’t help you in your discussions with your clients but this is all we can tell
you at this point. I believe we will have a better idea of any proposed amendments in the March-
April timeframe.

Hi Mark,
We have changed our direction somewhat from our last
workshop. ARB staff will propose the following for discussion at the
June 22 workshop.
Align the ATCM’s emission standards for new direct-drive fire pump
engines with the standards and implementation schedules required by the
NSPS final rule.
Align the ATCM’s emission standards for new emergency standby
engines with the NSPS emission standards for this subset of
stationary CI ICEs, except the ATCM will retain a minimum PM
emission limit of 0.15 g/bhp-hr (the NSPS requires a less stringent
PM standard for CI engines between 50 > hp <175 this hp range).
We are still investigating the issue we discussed earlier regarding a
subset of new emergency standby engines that are near sensitive
receptors or multiple engines at one location (e.g., data centers,
server banks, etc) that may require a more stringent PM emission
standard than what is required by the NSPS.
The ATCM will continue to allow upon district approval emergency
standby engines to operate > 50 hrs for M&T if the engine emits PM
at a rate < or equal to 0.01 g/bhp-hr.
Non-substantive changes to ATCM for clarity.
