                       SQGs comprise a wide range of commercial and industrial activities ranging from equipment repair
                       (degreasing and rust removal), to construction (paint preparation), to consumer service shops (e.g.,
                       auto repair). The range of SQGs along with the types of wastes produced are listed in Table 12.3.

                       12.3.3 EPA WASTE CODES FOR COMMON SQG WASTES
                       Some of the more common wastes generated by SQGs are discussed below. The U.S. EPA waste
                       codes are also provided for these wastes.
                          Solvents, spent solvents, solvent mixtures, or solvent still bottoms are often hazardous. The fol-
                       lowing are some commonly used hazardous solvents (also see ignitable wastes for other hazardous
                       solvents, and 40 CFR 261.31 for most listed hazardous waste solvents):
                          Benzene                  F005
                          Carbon disulfide         F005
                          Carbon tetrachloride     F001
                          Chlorobenzene            F002
                          Cresols                  F004
                          Cresylic acid            F004
