MINOR
The bill was amended from a draft version to a committee substitute, introducing significant changes to who must perform inspections and clarifying the relationship with state standards. The most critical change is that final inspections are now allowed to be performed by general contractors, whereas the original draft restricted this role to licensed engineering firms. Additionally, the bill now explicitly exempts the Department of Transportation from reviewing or approving installation plans and inspection reports.
Scope change
The scope of eligible entities performing final inspections was expanded to include general contractors in addition to licensed engineering firms.
REQUIREMENT
Expanded the list of qualified entities for final inspections to include 'any general contractor' alongside licensed engineering firms, removing the previous restriction to engineering firms only.
Added an explicit exception stating that the Department of Transportation is not required to review or approve installation plans, inspection videos, or inspection reports.
DEFINITION
Updated the text to specify that the standards apply to stormwater systems 'owned by' counties and municipalities, clarifying ownership rather than just location.
