The following represents a basic minimum timeline from receipt of a petition to the effective date of the listing/uplisting/downlisting/delisting of the species as threatened or endangered.

Day 1: The petition to list, uplist, downlist or delist a species is received in the Commission office and is reviewed by Commission staff for the presence or absence of the required information.

Day 10: An incomplete petition will be returned to the petitioner within 10 days. An accepted petition will be referred to the California Department of Fish and Wildlife (Department) within 10 days and a notice of receipt of the accepted petition will be published in the California Regulatory Notice Register (Notice Register) and mailed to interested and affected parties.

Day 100: The Department will evaluate the petition according to the criteria listed subsection 670.1(d)(1), Title 14, CCR, and will provide its evaluation report to the Commission within 90 days of receiving the petition from Commission staff; the Department may request a 30-day extension.

Day 130: The Commission will take action on the petition at its next available meeting after the Department's evaluation report has been available to the public for at least 30 days. At the meeting, the Commission will make a finding on whether the petition contains sufficient scientific information to indicate that the petitioned action may be warranted. If the Commission finds there is not sufficient scientific information to indicate that the petitioned action may be warranted, the process ends. If the Commission finds there is sufficient scientific information to indicate that the petitioned action may be warranted, the Commission will designate the species as a candidate species (Section 2068, Fish and Game Code).

Day 146: If the Commission designates the species as a candidate species, a notice of the Commission's findings will be published in the Notice Register and mailed to interested and affected parties.

Day 601: Final consideration of the petition will be scheduled for the next regularly-scheduled Commission meeting after receiving the status review report. The Commission will make a finding of whether the petitioned action is warranted. Adoption of the Commission's findings will be scheduled for a future meeting. If the Commission finds that the petitioned action is not warranted, the process ends and the species will be removed from the list of candidate species. If the Commission finds that the petitioned action is warranted, the species will be added to the list of threatened and endangered species in Section 670.2 (plants) or Section 670.5 (animals) through a regulation change.

Day 617: The notice of findings will be mailed to interested and affected parties and the regulation change filed with the California Office of Administrative Law, which has up to 30 business days to review the regulation change.
