Code Regs. tit. 17 §§94010, 94011, 94016, 94150, and 94168, which incorporate by reference vapor recovery definitions, certification procedures, and test procedures. Changes would clarify language giving owners of gas dispensing facilities four years to replace current equipment when new standards become effective.
