From Tom McKirgan of Oathkeepers
mentioned, however, it's called the "Federal Coordination Policy" #12.1231. You can view the PDF here. http://www.co.jackson.or.us/Files/Ch1231.pdf
Page 13 sec 7C affirms no restrictions to particular issues with the county's involvement. Also, above this on their site is another PDF on Chapter 49 "Vested Rights" which might have something to do with this as well. I only skimmed over it. #12.1230. http://www.co.jackson.or.us/Files/Ch1230.pdf
