(b) Schedules for compliance referred to in subdivision (a) shall not be subject to negotiation between the county and the violator.
(c) A county may take enforcement action, or refer for enforcement action, a violation subject to the policies adopted pursuant to subdivision (a) if the violation involves an imminent or substantial endangerment to public health and safety or the environment. If a county refers a violator for enforcement action to the appropriate state or local agency pursuant to this subdivision, the county shall include any recommendations for cleanup or abatement of the violation and information on whether the violator has voluntarily attempted to comply with the statute or regulation.
