This bill aims to exempt certain developments at commercial farms from being classified as major developments for stormwater management purposes. Specifically, it stipulates that any development at a commercial farm that creates 1.25 acres or less of regulated impervious surface or regulated motor vehicle surface, or a combination of both, will not be considered a major development. Consequently, these developments will not be subject to the associated requirements or permitting fees outlined in the Department of Environmental Protection's (DEP) stormwater management rules.

Additionally, the bill allows the DEP to establish new standards and requirements for these smaller developments at commercial farms, provided that such regulations are less stringent than those applicable to major developments. The sponsor of the bill argues that the current stormwater management regulations impose excessive costs and requirements on commercial farms, which do not align with the actual risk posed by stormwater runoff from these agricultural operations. An example cited is the significant increase in costs for a hay barn development due to compliance with existing regulations, which doubled the project's expenses.
