Aboveground Storage Tanks

                                                            Page under construction

The purpose of this program is to protect waters of the state (surface water and groundwater) from exposure to (petroleum-based) fluids stored in aboveground storage tanks by confirming compliance, for specified facilities, with the federal Spill Prevention, Control, and Countermeasure rule. This is achieved through routine, periodic, and complaint inspections, surveillance, enforcement, public education, and assistance to industry.
