Establishes EDA grant program to support increased business expenses incurred by certain businesses impacted by certain public highway projects; provides 50 percent sales and use tax exemption in impacted municipalities; appropriates $1 million.

This bill establishes a grant program administered by New Jersey's Economic Development Authority (EDA) to reimburse small retail businesses (with 50 or fewer employees) for increased operating costs caused by public highway projects. It also provides a 50% sales and use tax exemption for eligible businesses in municipalities affected by these projects. The grants cover the difference between a business's normal operating expenses and the increased costs during the project's duration, requiring documentation of both periods. The program is funded by a $1 million appropriation, with applications reviewed by the EDA using criteria defined in the bill.
