(1) The foreign party must provide a letter signed by the RCO that commits the foreign party to the applicable provisions specified in paragraphs (b)(4) and (c) of this section as part of their registration under § 80.135.

(A) The biogas producer's registration information submitted under §§ 80.135 and 80.1450.

(iii) As part of three-year engineering review updates required under § 80.135(b)(3) submitted on or after January 1, 2027, an RNG producer that injects RNG from an RNG production facility into a natural gas commercial pipeline system must sample and test a representative sample of all the following at least once every three years, as applicable:

(A) Report the date of the last engineering review conducted under §§ 80.135(b)(3) and 80.1450(b), as applicable.

(C) A renewable fuel producer seeking to generate D code 3 or D code 7 RINs or a biointermediate producer seeking to have its biointermediate made into cellulosic biofuel, who intends to produce biogas using two or more feedstocks converted simultaneously in an anaerobic digester, where at least one of the feedstocks does not have a minimum 75% adjusted cellulosic content, must supply the information specified in § 80.135(c)(10).

(E) A cellulosic conversion factor accepted at registration under § 80.135(c)(10)(vi).

(B) For the cellulosic converted fraction value specified in paragraph (j)(2)(iv)(E) of this section, the mixed digester must operate according to the conditions accepted at registration under § 80.135(c)(10)(vi)(A)(4).

(3) Other parameters must be measured and calculated as specified in the facility's registration under § 80.135(c)(10)(vi)(A)(4).

(3) Parties must test each daily representative sample under paragraphs (c)(1) and (2) of this section unless the party has a composite sampling plan submitted to EPA under § 80.135(c)(10)(vi)(D). Parties with a composite sampling plan must either test each daily representative sample or test samples in accordance with Part A of SM 2540 and as specified in the facility's composite sampling plan.

(11) Documentation of any waiver provided by the natural gas commercial pipeline system for any parameter of the RNG that does not meet the natural gas specifications submitted under § 80.135(d)(5).

(iii) Report as a finding any batches with reported values that did not meet the natural gas specifications submitted under § 80.135(d)(5).

(iv) A summary table with the results of the certificates of analysis required under paragraphs (d)(6)(i) through (iii) of this section and the natural gas specifications required under paragraph (d)(5) of this section converted to the same units.

(iv) A summary table with the results of the certificates of analysis required under paragraphs (d)(6)(i) through (iii) of this section and the natural gas specifications required under paragraph (d)(5) of this section converted to the same units.

(iv) A summary table with the results of the certificates of analysis required under paragraphs (d)(6)(i) through (iii) of this section and the natural gas specifications required under paragraph (d)(5) of this section converted to the same units.

(v) EPA may approve an RNG producer's request of an alternative analysis in lieu of the certificates of analysis and summary table required under paragraphs (d)(6)(i) through (iv) of this section if the RNG producer demonstrates that the alternative analysis provides information that is equivalent to that provided in the certificates of analysis and that the RNG will meet all natural gas specifications required under paragraph (d)(5) of this section.

(iv) A summary table with the results of the certificates of analysis required under paragraphs (d)(6)(i) through (iii) of this section and the natural gas specifications required under paragraph (d)(5) of this section converted to the same units.

(v) EPA may approve an RNG producer's request of an alternative analysis in lieu of the certificates of analysis and summary table required under paragraphs (d)(6)(i) through (iv) of this section if the RNG producer demonstrates that the alternative analysis provides information that is equivalent to that provided in the certificates of analysis and that the RNG will meet all natural gas specifications required under paragraph (d)(5) of this section.
