California UST System Operator Practice Test

The term UST stands for Underground Storage Tank in the context of environmental regulations. Underground Storage Tanks are primarily used to hold hazardous substances or petroleum products. These tanks are buried beneath the ground and are subject to specific regulations to ensure that they do not leak or contaminate the surrounding environment.

The significance of USTs in environmental regulations lies in their potential to release pollutants, which can have severe implications for soil and groundwater quality. Regulatory frameworks, such as those enforced by the U.S. Environmental Protection Agency (EPA) and state agencies, mandate regular inspections, maintenance, and monitoring of these tanks to minimize risks and ensure public health and safety.

Understanding the role and regulations surrounding Underground Storage Tanks is crucial for operators to maintain compliance and protect environmental resources effectively.
