Which of the following is necessary for ensuring the effectiveness of secondary containment?

Regular inspections are essential for ensuring the effectiveness of secondary containment because they allow operators to identify any signs of wear, damage, or leaks in the containment system. Through systematic and frequent evaluations, operators can assess the structural integrity of containment barriers and the functionality of systems designed to prevent spills. Inspections help in detecting issues before they escalate into significant problems, thereby ensuring that the secondary containment is functioning properly to protect the environment and comply with regulatory requirements.

Routine inspections also provide opportunities to verify that the containment area is free of debris, properly maintained, and ready to respond to potential spills or leaks. This proactive approach helps in maintaining compliance with stormwater management regulations and reduces the risks associated with hazardous materials storage and handling.

The other options, while relevant to overall site maintenance and effectiveness, do not directly address the continuous monitoring and proactive management aspect that regular inspections do.
