Can you tell me if contracts with waste haulers are required? My project is a small office building located on a college campus. Currently the office personnel or college students carry all recyclables to the city recycling collection points and do not receive a receipt. I know for compliance with MR credit 7-9 they will be required to quantify amounts, but can they do it themselves or are they going to be required to have a contract and pay a thrid party to do this? Thanks!
