NJ S3891

Establishes the "Small Business Interruption Grant Program" through the New Jersey Economic Development Authority to provide grants to small businesses that have suffered economic loss due to extended closures (one month or longer) caused by prolonged state or public entity infrastructure and construction projects

Defines eligible small businesses as independently owned operations with fewer than 10 employees and annual gross revenue of $1,500,000 or less

Creates the "Small Business Interruption Grant Program Fund," funded by contributions from entities responsible for infrastructure projects, with each contributing between zero and five percent of estimated total project costs

Grant amounts will be determined based on operating expenses incurred by the small business during the extended closure, with eligibility applying to losses suffered both before and after the bill's effective date

Requires the EDA to collaborate with state and local entities to ensure infrastructure project timeframes include specific start dates to help affected businesses determine their eligibility for grant funding
