Recycling dropoff is normally free in North America. Waste that cannot be recycled is typically charged by weight for the cost of disposal at waste facilities. You can visit either as often as you like, but will pay to have your garbage disposed of. The GP lives in a place where you do not have to pay for non-recyclable waste the first two times you visit per year. This is normally done to encourage people with a large volume of waste from a single cleanup to dispose of waste properly (dumping on vacant land is a big problem in many parts of NA).
