MINOR
The bill was updated to reflect House District 1 (HD1) amendments, changing the bill title and sponsor information. The most significant policy change is the redefinition of 'agricultural ponds' to 'agricultural infrastructure,' broadening the scope of the exemption to include other agricultural structures beyond just ponds. Additionally, the effective date of the law was drastically changed from July 1, 2026, to July 1, 3000, effectively delaying the implementation of these regulations indefinitely.
Scope change
The bill's scope was expanded by changing the term 'agricultural ponds' to 'agricultural infrastructure,' allowing more types of agricultural facilities to be exempt from stormwater safety regulations. The applicability timeline was also altered to remove the 2026 effective date.
