Good Morning Nancy

–

We currently have one source (a dairy) that is large enough to be subject to our Rule 11.2. A second dairy, which was

subject to our rule in the past, has gotten smaller and is still operating but is no longer large enough to be governed by

the rule.

So at the moment, only one source is large enough to be subject to our Confined Animal Facility rule.

Please just let me know if you have any other questions.

Regards,

Matt Jones

Hi Nancy

–

I will have to check into this with our permitting staff and get back to you. Our dairy sources have changed over time

and I need to make sure that the information is still accurate. I should be able to have an answer for you by the end of

the week.

### Hi Matt,

I’m doing a write up to act on the submittal of Rule 11.2 CAFs, which has been sitting in our backlog

for a while. In the write up I want to correctly characterize the size and number of CAFs in the District

– Here’s what I have from page 19 of the staff report for Rule 11.2. Can you let me know if there are

any changes? Thanks!

(on page 19 of staff report) CH&SC 40724.6(e)(1) - Source Category Impact

“The District has worked, in conjunction with other local agencies (Solano County Resource

Management Department, Solano County Agricultural Commissioner’s Office, and Yolo County

Agricultural Commissioner’s Office), to research and identify existing CAF operations within the

District. The District estimates that there are less than ten (10) existing CAFs of significant size

(livestock count greater than 25% of any Large CAF definition threshold) operating within the

District’s jurisdiction. Of those, the District estimates that two (2) existing CAF operations (with

approximately 2,000-3,000 dairy cows each) will be required to submit a CAF Permit application

and two (2) more (approximately 500-1,000 dairy cows each) that will be required to maintain

records per Section 502 of proposed Rule 11.2. Any new CAF with a livestock count greater than

50% of any Large CAF definition threshold will be required to maintain records, at a minimum, or

obtain a CAF Permit prior to operating.”

Nancy Levin
