What is the minimum time frame in which double-walled spill buckets must be tested for liquid tightness after monitoring ceases?

The minimum time frame for testing double-walled spill buckets for liquid tightness after monitoring ceases is indeed 12 months. This requirement is established to ensure the integrity and safety of underground storage tank systems.

Double-walled spill buckets are designed to contain any spills or overfill from dispensers, preventing hazardous materials from leaking into the environment. Regular testing for liquid tightness is essential in maintaining compliance with environmental regulations and ensuring that the spill buckets are functioning correctly.

Testing every 12 months helps identify any potential weaknesses or failures in the containment system that could lead to environmental contamination. This annual testing requirement is part of a broader regulatory framework aimed at protecting groundwater and minimizing the risks associated with underground storage tanks. By ensuring that these components are tested regularly, operators can help mitigate the risk of leaks and spills, safeguarding both public health and the environment.
