The Environmental Protection Agency regulations regarding spent sulfuric acid as set forth in Section 261.4(a)(7) of Title 40 of the Code of Federal Regulations (50 Fed. Reg. 665) are the regulations of the department and shall remain in effect until the department adopts regulations regarding this subject. It is the intent of the Legislature that the regulations adopted by the department be at least equivalent to, and in substantial conformance with that Section 261.4(a)(7). Further, it is the intent of the Legislature that the department may define in the regulations the term "spent sulfuric acid" as it deems necessary to avoid sham recycling, as described on page 638 of Volume 50 of the Federal Register by the Environmental Protection Agency.
