I have tank facilities located in different counties. Why are they regulated differently?     

The Health & Safety Code and California Code of Regulations provide the laws and regulations that apply to all underground storage tanks in California. Each local Agency must determine how to best implement these laws and regulations. An agency may enact local ordinances to impose additional conditions and restrictions. Environmental Health (CUPA) follows state guidelines and does not currently impose any additional requirements.

Many local agencies participate in UST advisory meetings in an effort to share information to develop a consistent approach to tank regulation.
