(1) Question: It is possible for DART to generate RINs through a contractual mechanism approved by the EPA under "Book and Claim" methodology versus physical delivery of the molecule. The majority of RNG "delivered" in the US falls under the book and claim model approved by the EPA to generate/separate a D3 RIN. Will DART accept "delivery" of RNG through the EPA-approved "Book and Claim" system to generate D3 RINs?

(1) Answer: DART will accept “delivery” of Renewable Natural Gas (RNG) through an EPA-approved Book-and-

Claim methodology for the purpose of generating and separating D3 RINs, provided the Contractor complies with all contract requirements and RFS program rules.

(2) Question: The cost pricing schedule form has "OFFERED ANNUAL FIXED RIN D3 CODE" for 2026 to 2030 and is asking for Bidders to put in a dollar amount. The D3 RIN market fluctuates based on a variety of factors outside the control of Bidders. Will DART allow Bidders to use a neutral third-party index (OPIS/ARGUS) to determine the price of D3 RINs in the month/year they're generated?

(2) Answer: Please refer to Solicitation Amendment 1 for the updated Cost/Pricing Schedule and Exhibit D, Special Provision.

All other Terms and Conditions remain unchanged. The Amendment can be found under the Bonfire Portal Supporting Documentation section of Solicitation no. 2093872
