CA AB1500

Repeals authority for unified program agencies (UPAs) to suspend or revoke permits solely for non-payment of fees; now allows UPAs to withhold permit issuance in addition to suspension or revocation for non-payment.

Requires UPAs to collectively develop criteria and factors for determining imminent or substantial endangerment to public health, safety, or environment before suspending, revoking, or withholding permits; all determinations must be supported by written findings.

Establishes civil or administrative penalty of $500 to $5,000 per day for failure to obtain or keep a required unified program facility permit.

Expands hazardous material release reporting requirements: facilities subject to the program must report upon discovery; other facilities must report only if release results in emergency response; requires handlers to provide emergency personnel access to facilities if release or threatened release occurs.

Authorizes director of Public Health or local health officer to immediately suspend activities and take protective actions without declaring a health emergency if hazardous waste or substance release poses imminent or substantial endangerment; responsible party liable for costs incurred.
