Yolo County Environmental Health Office maintains files for

  • each permitted underground storage tank
  • tanks closed under permit
  • leaky underground tank sites
  • each facility required to submit hazardous waste unit
  • site specific treatment
  • disposal permit notifications
  • every site known to the county where a cleanup or investigation of hazardous wastes is or has occurred under federal, state, or local oversite.
  • each facility required to obtain a permit from Environmental Health, such as restaurants and public pools.

All of these files may be reviewed by the public in-office or online except when formal county prosecution for violations of law is in progress or pending.

Yolo County Environmental Health is currently in the process of transferring all of our paper files to an electronic format. Many of our files including those regarding leaky underground storage tank sites have already been transferred and are currently available in ONBASE. We anticipate that those files not already converted will all be available in the short future. However, please browse through ONBASE before making an appointment with the Environmental Health Department.

For further information regarding electronic file reviews please call at (530) 666-8646.





  1. Reviewers shall be polite to staff and other reviewers at all times.
  2. Files shall be returned in the same condition and order received.
    • We attempt to arrange contents of files in chronological order from the oldest to the most recent. Some cases have two or more files, where each case is numbered, and each file for each case is labeled with the case number followed by a letter.
      EXAMPLE: Case number 101 may include 101A, 101B and 101C.
  3. No document within a file shall be removed from the office, nor shall any comments or marks be made on any document within the file.
    • If you would like to add materials to a file, it must be given to a Hazardous Materials Specialist for review and approval. Do not place any material directly into a file.
  4. When a copy of file contents is requested, use Post-It Notes (available from clerical staff) to identify the pages to be copied.
    • If the document is multi-page and every page needs to be copied, place only one Post-it Note stating “all” on the note. If only selected pages need to be copied, either post a Post-it on each page that needs to be copied or indicate the page numbers on the Post-It Note. However, there will be a surcharge for each copy made by an county staff. (See In-office Copy Fees for more details)




File reviews are available during normal business hours at the Environmental Health office, by walk-in or appointment. We only have 1 computer for the public to use to view file review, so it is recommended to make an appointment to reserve the computer.

  • If the reviewers want a packet prepared with their records, please must submit a list of files that they want to Environmental Health at least ONE WEEK in advance. For a fee, this packet can be made into a CD for the viewer's convenience

An appointment can be made by faxing a list of addresses & parcel numbers along with the date and time you would like to view the files.  Fax: (530) 669-1448.




All files are free to review. However, fees are only applied when county staff member(s) are asked to make copies or create a CD file by the reviewer.

  • If hard copies are needed, there is a charge of $0.31 per page.
  • For the convenience of the public, files can also be converted to an electronic format on a CD. The CD will contain the entire file plus necessary “viewers” to open the files on a personal computer outside of the Yolo County Environmental Health office. The cost of a CD is $152.00 per hour for time spent preparing and creating the disc. If multiple facility files are requested it is also possible to include them all on a single disc (disc space permitting).

**Reviewers can bring their own USB to save the file(s) or bring their own printers to the Environmental Health office to print their own copies. However, prints are only free if you bring in your own working printer and paper. To an extent, space and power supply will be provided to reviewers who bring their own printing equipment. To insure access to space and electrical power, reviewers are encourage to note that they want to use the self-service printing method when submitting the file review request.
