For how many years must all field inspections, SWPPP documents, and related photos be retained?

The requirement to retain all field inspections, Storm Water Pollution Prevention Plan (SWPPP) documents, and related photos for a period of three years is established to ensure compliance with regulations and to maintain a thorough record of any activities that may impact stormwater management. This three-year retention period aligns with the standards set by various regulatory frameworks, ensuring that documentation is available for review if necessary. The span allows for adequate monitoring and ensures that any site-related issues can be tracked and addressed based on historical data. Retaining these records for three years strikes a balance between regulatory compliance and practical archival needs.
