MODERATE
The bill was revised to clarify inspection requirements and adjust submission deadlines for stormwater management systems. The changes add a new annual inspection requirement for identified infrastructure starting June 1, 2027, and shift the checklist submission deadline from June 1 to September 1 for ongoing compliance.
Scope change
The bill's scope expanded to include a recurring annual inspection requirement for specific infrastructure components identified during the initial inspection, rather than only requiring a one-time inspection.
REQUIREMENT
Added a new subsection (c) requiring annual inspections of identified infrastructure starting June 1, 2027, following the initial September 1, 2026 inspection.
Modified the initial inspection requirement to explicitly include a September 1, 2026 deadline for completing the inspection and submitting the checklist.
TIMELINE
Changed the recurring checklist submission deadline from June 1 to September 1 each year to align with the new annual inspection schedule.
DEFINITION
Added a new subsection (d) clarifying that the inspection checklist must be completed any time an MS4 is inspected under this subsection.
