Secondary containment testing results must be submitted to the local agency within _____ days.

The requirement to submit secondary containment testing results within a specific timeframe is established by environmental regulations to ensure that underground storage tank systems are monitored and maintained properly. Submitting these results within 30 days ensures that the responsible parties stay compliant with regulations intended to protect the environment and public health.

Prompt submission helps local agencies monitor potential leaks and assess the integrity of containment systems in a timely manner, which can prevent environmental contamination and enhance safety protocols. Compliance with this 30-day submission timeline aligns with best practices in environmental management for operators of storage tank systems.

The other timeframes do not adhere to this regulatory requirement, which emphasizes the importance of rapid reporting to facilitate quick response actions if issues are detected during testing.
