(iv) Vehicles are subject to all the other requirements specified in this section.
(2) Small-volume manufacturers may delay complying with all the requirements of this section until model year 2022, and instead meet all the requirements that apply to Tier 2 vehicles under § 86.1811–10 for 2021 and earlier model years.
(3) If meeting the Tier 3 standards would cause severe economic hardship, small-volume manufacturers may ask us to approve an extended compliance deadline under the provisions of 40 CFR 1068.250, except that the solvency criterion does not apply and there is no maximum duration of the hardship relief.
