# §80.100. Scope and application.

- (a) **Applicability.**
  - (1) **The provisions of this subpart E apply to all the following—**
    - (i) **Biogas.**
    - (ii) **Treated biogas.**
    - (iii) **Biogas-derived renewable fuel.**
    - (iv) **RNG used to produce a biogas-derived renewable fuel.**
    - (v) **RINs generated for RNG or a biogas-derived renewable fuel.**
  - (2) This subpart also specifies requirements for specified parties that engage in activities associated with the production, distribution, transfer, or use of biogas, treated biogas, biogas-derived renewable fuel, RNG used to produce a biogas-derived renewable fuel, and RINs generated for a biogas-derived renewable fuel under the RFS program.
- (b) **Relationship to other fuels regulations.**
  - (1) The provisions of subpart M of this part also apply to the parties and products regulated under this subpart E.
  - (2) The provisions of [40 CFR part 1090](/cfr/40/part1090.md) include provisions that may apply to the parties and products regulated under this subpart E.
  - (3) Parties and products subject to this subpart E may need to register a fuel or fuel additive under [40 CFR part 79](/cfr/40/part79.md).
- (c) **Geographic scope.** RINs must only be generated for biogas-derived renewable fuel used in the covered location.
- (d) **Implementation dates—**
  - (1) **General.** The provisions of this subpart E apply beginning July 1, 2024, unless otherwise specified.
  - (2) **Registration.**
    - (i) Parties not registered to generate RINs under § [80.1426(f)(10)(ii)](/cfr/40/80.1426.md?p=f-10-ii) or [(11)(ii)](/cfr/40/80.1426.md?p=f-11-ii) prior to July 1, 2024, must register with EPA under [§ 80.135](/cfr/40/80.135.md). EPA will not accept registration submissions for the generation of RINs under § [80.1426(f)(10)(ii)](/cfr/40/80.1426.md?p=f-10-ii) and [(11)(ii)](/cfr/40/80.1426.md?p=f-11-ii) on or after July 1, 2024.
    - (ii) Parties registered to generate RINs under § [80.1426(f)(10)(ii)](/cfr/40/80.1426.md?p=f-10-ii) or [(11)(ii)](/cfr/40/80.1426.md?p=f-11-ii) must submit updated registration information under [§ 80.135](/cfr/40/80.135.md) no later than October 1, 2024.
    - (iii) Independent third-party engineers may conduct engineering reviews for parties required to register under [§ 80.135](/cfr/40/80.135.md) prior to July 1, 2024, as long as the engineering review satisfies all applicable requirements under §§ [80.135](/cfr/40/80.135.md) and [80.1450](/cfr/40/80.1450.md).
  - (3) **Generation of RINs for RNG.** RNG producers may only generate RINs for RNG produced on or after July 1, 2024, as specified in [§ 80.125](/cfr/40/80.125.md).
  - (4) **Generation of RINs for renewable CNG/LNG for previously registered facilities.**
    - (i)
      - (A) Prior to January 1, 2025, RIN generators may generate RINs as specified in § [80.1426(f)(10)(ii)](/cfr/40/80.1426.md?p=f-10-ii) or [(11)(ii)](/cfr/40/80.1426.md?p=f-11-ii) for renewable CNG/LNG produced from a facility covered by a registration accepted by EPA under [§ 80.1450(b)](/cfr/40/80.1450.md?p=b) prior to July 1, 2024.
      - (B) Biogas or RNG produced under a registration accepted by EPA under [§ 80.1450(b)](/cfr/40/80.1450.md?p=b) for the generation of RINs as specified in § [80.1426(f)(10)(ii)](/cfr/40/80.1426.md?p=f-10-ii) or [(11)(ii)](/cfr/40/80.1426.md?p=f-11-ii) prior to July 1, 2024, may only be used to generate RINs for renewable CNG/LNG.
    - (ii) For biogas produced on or after January 1, 2025, biogas closed distribution system RIN generators must generate RINs for renewable CNG/LNG as specified in [§ 80.130](/cfr/40/80.130.md).
  - (5) **Generation of RINs for renewable fuel produced from biogas used as a biointermediate.** Renewable fuel producers must only generate RINs for renewable fuel produced from biogas used as a biointermediate produced on or after July 1, 2024.
