The Grease Trap Assistance Program is a revolving fund to help credit-worthy businesses spread the cost of grease trap upgrades over one or two years by offering zero-percent interest loans. 

Loans for infrastructure upgrades can be provided up to $5,000 or 50% of the total replacement costs, whichever comes first. 

Loans will be awarded out on a first come first serve basis.
