The Environmental Protection Agency (EPA) establishes requirements for owners and operators of non-hazardous waste landfills that require bonds. These bonds are written by surety companies that specialize in them and other miscellaneous bonds. The bond program for non-hazardous waste landfills is designed for municipal solid waste landfills and demolition facilities. The financial responsibility may be accomplished through bonding, insurance, letters of credit, or trusts. The terms of the bond require that the operator continue to monitor the ground cover and ground water and maintain the landfill for 30 years after it is closed. This bond guarantees that the operator will perform such monitoring and required maintenance.
