The municipal separate storm sewer system (MS4) General Permit requires inspections of certain municipally owned/operated facilities, areas, or stormwater best management practices (BMPs) (MS4 General Permit Part III.D.6.e). This includes:

• Annual inspections of structural stormwater BMPs to determine structural integrity, function, and maintenance needs.
• At least one inspection every permit term of stormwater ponds and outfalls to determine structural integrity, function, and maintenance needs.
• Quarterly inspections of stockpiles, and storage and material handling areas identified in the Facility Inventory to determine function and maintenance needs.

During each of these inspections, inspectors must look for evidence of illicit discharges (MS4 General Permit Part III.D.3.c.). All inspections must be documented (MS4 General Permit Part III.D.6.h.(1)).
