Each year qualified personnel should conduct a site compliance evaluation which would inspect all drainage areas for evidence of pollutants, evaluate good housekeeping measures, observe structural measures, and inspect all sites for problems. The plan should be revised if needed within 2 weeks of inspection, and changes should be implemented within 12 weeks. A report of all findings should be prepared and signed, and kept with the plan.
Records of all spills, leaks, inspections, and maintenance activities should be maintained for at least one year after the permit expires. Date, times, weather conditions, causes, and resulting problems should all be noted.
Any change in a facilities design, construction, or maintenance will necessitate changes in the plan.
