(a)
Except as specified in paragraph (c) of this section, the prohibitions in § 94.1103(a)(1) do not apply to a new engine that is subject to Tier 2 standards according to the following provisions:
(1)
The engine must be intended for installation in a lifeboat or a rescue boat as specified in 40 CFR 1042.625(a)(1)(i) or (ii).
(2)
This exemption is available from the initial effective date for the Tier 2 standards until the engine model (or an engine of comparable size, weight, and performance) has been certified as complying with the Tier 2 standards and Coast Guard requirements. For example, this exemption would apply for new engine models that have not yet been certified to the Tier 2 standards.
(3)
The engine must meet the Tier 1 emission standards specified in § 94.8.
(b)
If you introduce an engine into U.S. commerce under this section, you must meet the labeling requirements in § 94.212, but add the following statement instead of the compliance statement in § 94.212(b)(6) :
(c)
Introducing into commerce a vessel containing an engine exempted under this section violates the prohibitions in § 94.1103(a)(1) where the vessel is not a lifeboat or rescue boat, unless it is exempt under a different provision. Similarly, using such an engine or vessel as something other than a lifeboat or rescue boat as specified in paragraph (a) of this section violates the prohibitions in § 94.1103(a)(1), unless it is exempt under a different provision.
