Not all construction industry operations produce hazardous waste, but if you use materials such as strong acid or alkaline solutions, paints, solvents, or petroleum products, the waste generated during their use might be hazardous. Ignitable paint wastes generated by painting and other associated processes, including paint preparation and brush and spray gun cleaning Other ignitable wastes containing paint and varnish removers, paint brush cleaners, and epoxy resins and adhesives used during processes such as painting, cleaning, and degreasing Spent solvents from many processes, including painting, cleaning, degreasing, air conditioner maintenance, and fluxing Wastes containing toxic chemicals. Many products such as adhesives, paints, coatings, polishes, varnishes, thinners, and treated woods contain toxic chemicals. Wastes generated during the use of such products are hazardous wastes if they contain certain levels of toxic chemicals.
Some businesses generate spent heat transfer boxes that contain PCBs.
If you have spent hear transfer boxes, contact your state hazardous waste management agency to determine your responsibilities. In addition to these wastes, your operations might generate used oil. There are special provisions in the regulations for used oil. Currently most used oil is exempt from EPA hazardous waste regulations if it is recycled. If you recycle your oil, you are not required to use a Uniform Hazardous Waste Manifest.
