Exempts certain water quality management structures, funded by certain federal and State grants, from real property taxation.

This bill exempts specific water quality management structures from real property taxes if they are funded by federal or state grants. It directly affects property owners who have installed these structures, such as those built with money from the USDA or the State Agriculture Development Committee, to improve water quality. To qualify, the enforcing agency in the local municipality must certify the structure, a process that includes inspections and the submission of written applications. The exemption reduces the taxable value of the property by the amount attributed to the structure, and the agency retains the power to revoke the status if the structure is misused, abandoned, or obtained through fraud.
