Solid Waste: All solid, semisolid, and liquid wastes, including garbage, trash, refuse, paper, rubbish, ashes, industrial wastes, demolition and construction wastes, dewatered, treated, or chemically fixed sewage sludge which is not hazardous waste, manure, vegetable or animal solid and semisolid wastes, and other discarded solid and semisolid wastes. "Solid waste" does not include hazardous waste, radioactive waste, or medical waste as defined or regulated by State law.

1.05 HAZARDOUS MATERIALS

A. Hazardous building materials include, but are not limited to, asbestos and lead based paint.

B. This facility has been surveyed and tested by an independent laboratory for the presence of asbestos and lead based paint. Both asbestos and lead based paint were found to be present in this facility. See attachment 6, Asbestos and Lead Reports for location and concentration of asbestos and lead based paint.

Abatement has been included as individual line items in the Section B. The contractor must follow all local, state, and federal regulations for removal and transportation of the hazardous material.

C. Asbestos – See attached Asbestos Report dated June 8, 2016.

1. Friable ACM will easily release fibers when crushed. Only California licensed asbestos abatement contractors and certified asbestos workers can remove and dispose of Friable ACM. Examples of friable ACM can include, but are not limited to the following: sheet vinyl flooring, insulation on piping, duct and boilers, fireproofing, ceiling texture and panel products, and soundproofing.

2. Nonfriable ACM has a binder that holds the asbestos fibers within a solid matrix and will not allow asbestos fibers to release easily, unless mishandled, damaged, or in badly worn or weathered condition. A California licensed asbestos abatement contractor or a certified asbestos worker is not required to perform nonfriable asbestos abatement or removal. However, the nonfriable materials must remain in nonfriable condition (predominantly whole pieces) during the removal and disposal process. Examples of nonfriable ACM can include, but are not limited to the following: vinyl floor tile, AC water pipe, and cement (transite) siding or roofing.

a. If you remove nonfriable ACM, follow the California guidance documents.
