1. (a) Low Permeation Tanks -- Metal tanks, coextruded multilayer tanks, and structurally integrated nylon fuel tanks on SORE equipment with engine displacements < 80 cc are specifically exempt from section 2755 of this Article through model year 2019. Tank permeation data is not required to be submitted in the certification application. This exemption shall not apply to model year 2020 and subsequent model year evaporative emission control systems or fuel tanks.

2. (b) Small Production Volume Tank Exemption. These engines or equipment qualifying under section 2752(a)(34) are exempt from the diurnal standards in section 2754 and the fuel tank permeation standard in section 2754 of this Article through model year 2019 if the equipment contains the following:

   1. (1) An evaporative emission control system certified by an engine manufacturer that uses an actively-purged carbon canister, an equivalent fuel line, and a sealed tethered fuel cap; or

   2. (2) An evaporative emission control system that passively vents fuel tank vapors to a carbon canister with a minimum butane working capacity as specified in TP-902, an equivalent fuel line, and a sealed tethered fuel cap.

      Tank permeation data is not required to be submitted in the certification application for Small Production Volume Tanks. This exemption shall not apply to model year 2020 and subsequent model year evaporative emission control systems or fuel tanks.

3. (c) Equipment Fueled by a Vehicle Fuel Tank -- Generators that are fueled from the fuel tank of an on-road motor vehicle or marine vessel are exempt from the diurnal emission, hot soak plus diurnal emission, fuel tank permeation, and carbon canister design standards in section 2754. However, these generators must use fuel lines that meet the design standard specified in section 2754.
