### 1. The district originally chose to amend AV Rule 701 at the January 21, 2014 Governing Board

meeting. This action was published on December 20, 2013. The District took no action at the time on

the proposed amendment. After further review, the District has decided to incorporate the ARB

comment into the Rule and proceed with the amendment. Attachment 2 has been modified to reflect

the PM criteria as developed by OEHHA and others for the Wildfire Smoke Guide.

Re: Draft Rule 701, Air Pollution Emergency Contingency Actions, dated

February 12, 2014

We are providing comments based on our preliminary review of the draft rule identified above. We support the

District's efforts to update the rule and lower the thresholds for episode criteria for particulate matter. Please direct

any questions about our comments to me at (415) 947

- 4115 or to Nicole Law at (415) 947

- 4126.

- In Attachment 1 to the Rule on page 701

- 9, paragraph (b) should be edited to read that the health advisory

episode applies only to Ozone and PM2.5 since the District is introducing a health advisory level for PM2. 5 in

Attachment 2 Episode Criteria.
