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 proper format and 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 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; however, 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 30 days. At the meeting, the Commission will make a finding on whether or not the petition contains sufficient scientific information to indicate that the petitioned action may be warranted. 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: A notice of the Commission's findings will be published in the Notice Register and mailed to interested and affected parties. 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 process continues.

Day 511: Within 12 months of the date of publication of the "candidacy" notice, the Department will prepare and submit a Status Report to the Commission.

Day 541: The Commission will receive the Department's Status Report at a regularly scheduled Commission meeting.

Day 601: Final consideration of the petition will be scheduled for the next regularly scheduled Commission meeting after official receipt of the Status Report. At this meeting, the Commission will make a finding of whether or not the petitioned action is warranted. Ratification of the 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, a rulemaking process to add the species to the list of threatened and endangered species in Section 670.2 (plants) or Section 670.5 (animals) will begin.

Day 617: Notice of Findings and, if applicable, Notice of Proposed Changes in Regulations published in the Notice Register and mailed to interested and affected parties.
