California ICC UST Inspector Practice Exam

Site-specific variances from UST construction requirements must be approved by which agency?

1. State Water Resources Board

2. Local agency

3. Certified Unified Program Agency

4. Regional Water Quality Control Board

The correct answer is: Regional Water Quality Control Board

Site-specific variances from Underground Storage Tank (UST) construction requirements are essential for addressing unique conditions that may not fit the standard regulations. The appropriate agency responsible for approving these variances is the Regional Water Quality Control Board. This board plays a crucial role in overseeing water quality and safeguarding public health by ensuring that the management of USTs mitigates any potential risks to water resources. They are equipped to assess the specifics of the site, including geological and hydrological factors, and determine whether deviations from the standard requirements can still provide necessary protection to the environment and nearby water sources. Other agencies listed have their respective responsibilities, but they do not typically hold the authority to grant variances directly related to UST construction. The State Water Resources Board oversees broader water resource management, the local agency focuses on local codes and regulations, and the Certified Unified Program Agency administers local hazardous materials programs but does not specifically deal with UST variances. Hence, the Regional Water Quality Control Board is the appropriate agency for these approvals.
