The regulations under this chapter applicable to vapor recovery with respect to mobile source fuels at retail outlets of such fuels shall provide that the cost of procurement and installation of such vapor recovery shall be borne by the owner of such outlet (as determined under such regulations). Except as provided in subsection (b), such regulations shall provide that no lease of a retail outlet by the owner thereof which is entered into or renewed after August 7, 1977, may provide for a payment by the lessee of the cost of procurement and installation of vapor recovery equipment. Such regulations shall also provide that the cost of procurement and installation of vapor recovery equipment may be recovered by the owner of such outlet by means of price increases in the cost of any product sold by such owner, notwithstanding any provision of law.

The regulations of the Administrator referred to in subsection (a) shall permit a lease of a retail outlet to provide for payment by the lessee of the cost of procurement and installation of vapor recovery equipment over a reasonable period (as determined in accordance with such regulations), if the owner of such outlet does not sell, trade in, or otherwise dispense any product at wholesale or retail at such outlet.
