Underground Storage Tanks (USTs)

UST Mission & Program

The ENIPC Inc.-OETA UST mission is to promote and preserve Tribal environments and investments. The OETA UST Program assists Pueblos and Tribes with tank and related concerns to enhance tribal values, cultures, lands and health.
The Resource Conservation and Recovery Act (RCAC) establishes the authority to regulate underground storage tanks (USTs). A UST system is defined as a tank and any underground piping connected to the tank that has at least 10% of its combined volume underground. This definition includes the tank, connected underground piping, any underground equipment, such as valves and pumps and containment systems.

Many Pueblos and tribes operate gas stations which provide opportunities for economic development and services to the community. USTs and piping are buried at gas stations and contain fuel until pumped into your vehicle.

Our goals are to increase public safety and environmental health by assisting tribal UST facilities improve leak detection and prevention, as well as identifying abandoned USTs and facilitating communication among tribal UST stakeholders.

We offer compliance assistance, training, workshops, assist with opening and closing UST facilities and much more.

Why Monitor USTs?

Because USTs are underground, it is easy to forget about them. Just one gallon of gasoline can contaminate up to five million gallons of drinking water!

There are about 200 USTs on tribal lands in New Mexico and millions of USTs nationwide.

Compliance assistance providers help regulate communities and businesses comply with environmental laws through one-to-one counseling, online resource centers, fact sheets, guides and training.

What is Compliance Assistance?

Compliance assistance means helping businesses, federal facilities, local governments and tribes meet their environmental regulatory requirements.

To protect health and water, USTs are regulated by environmental laws. USTs are operating in compliance when documents are maintained showing tanks, lines and equipment are properly installed, registered, insured, protected from corrosion, regularly monitored, and tested.

We offer assistance with record keeping systems, on and off-site training, and informative walk-through visits so your tribal UST facility is prepared for inspections and operating safely.

Compliance assistance is most effective when used in an integrated strategy combining compliance monitoring (inspections), compliance incentives and auditing (self-disclosure policies), and enforcement.
