California has been listed as a state that has capital punishments but hasn't actually executed anyone in more than 10 years.
Corrections officials are expected to meet this week to discuss a revised submission of lethal injection rules to state regulators.
The proposed rules give executioners 10 minutes to administer each round of lethal drugs.
The first round is meant to kill the inmate, but if it fails, four more doses are administered with a 10 minute countdown clock.
The California Supreme Court is expected to rule in August about a ballot initiative that would speed up executions by reducing the time allowed to file appeals.
California has the largest death row population with almost 750 inmates.
