These proposed final budgets look reasonable. The “ARB adjustments” are pretty small especially for NOx in 2014-2018 

and are likely to be even smaller in the future years, so it should be no issue to be optional in future years. 

Thanks to you all for taking care of these budgets while I was away! Very much appreciated!

All,

 Just talked to Cari (ARB) and got confirmation that the final budgets, which include the safety margin, extend out to all 

future milestone years. However the “off model reductions” (“ARB adjustments” in the attached table) is optional for 

the future years. Another word, if we could pass the budget test without it, just leave it out. Attached table reflects the 

confirmation. So we are ok with a bit more breathing room for both areas. Please let me know if you have any 

questions. 

Thank you,

Jonathan, 

 I will confirm with Cari on the extension of both ARB adjustment and safety margin for future milestone years. 

Thank you.

Jonathan,

These safety margins obviously give us more room in both areas for the three years. However we are 

still nervously tight for ROG in 2020, 2030 and 2035, especially Coachella Valley (see row 48 and 49, in 

attached “Summary_wSafetyMargin” worksheet). 

Thank you,

Thanks. They are posting on Monday, so any concerns I would need to know tomorrow (I plan to call 

Cari back tomorrow). I’ll be out of the office but available by cell phone or email.

Hello Rongsheng. We were able to incorporate a safety margin in both sets of conformity budgets for 

the Coachella and Western Mohave Ozone SIP updates; see attached excerpt. Note that this item has 

not been released for public review at this time and the complete update / staff report is scheduled to 

be posted on Monday, August 18. Please contact me if you have questions or comments. Thanks.
