B. In cases where this chapter specifies that procedures or methods shall be approved by, acceptable to or determined by the director or the department or specifically provides for decisions to be made by the director or the department, it may be necessary to have such actions (approvals, determinations, exemptions, exclusions, or decisions) reviewed and confirmed as acceptable or approved by the U.S. Environmental Protection Agency in order to make them federally enforceable.
