Section 86.113–15 includes text that specifies requirements that differ from § 86.113–94. Where a paragraph in § 86.113–94 is identical and applicable to § 86.113–15, this may be indicated by specifying the corresponding paragraph and the statement “[Reserved]. For guidance see § 86.113–94.”

(a) Gasoline fuel. This paragraph (a) describes how to transition to an ethanol-blend test fuel for vehicles certified under subpart S of this part. You may use the test fuels specified in § 86.113–04(a) for vehicles that are not yet subject to testing with the new fuel. You may use the specified ethanol-blend test fuel anytime earlier than we specify as long as you use the corresponding procedures for measuring and calculating emission results. See 40 CFR 600.117 for special provisions that apply for emission measurements related to fuel economy and greenhouse gases. Manufacturers must certify using E10 test fuel as specified in 40 CFR part 1065, subpart H, and service accumulation fuel meeting applicable specifications as follows:

(1) Except as allowed under paragraph (a)(2) of this section, Use E10 test fuel to demonstrate compliance with the Tier 3 exhaust emission standards as specified in § 86.1811 and 86.1816, and to demonstrate compliance with the Tier 3 evaporative emission standards as specified in § 86.1813.
