Instructions for RFS2 New Fuel Pathway Determinations
EPA has established a process to assess and determine if new fuel pathways achieve Greenhouse Gas (GHG) reduction thresholds qualifying them for use under the RFS2 regulations. See this general information and instructions on how to request EPA evaluation and determination of any new fuel pathway not listed in 40 CFR 80.1426.

RFS2 Remedial Action Guidance
As in RFS1, EPA has been made aware of certain situations that are violations of the regulations where remedial actions have been requested. For more information, please visit the RFS2 Remedial Action Guidance webpage.
RFS2 Engineering Review Guidance
These documents provide guidance to independent third party professional engineers who will be conducting the engineering review for renewable fuel producers as part of their registration requirement for RFS2. They also serve to clarify registration reporting deadlines as well as requirements for submitting supporting registration documents, such as applicable permits, facility records, supplemental plans, etc.
Most renewable fuel producers are required to submit all required information for registration, including copies of applicable permits, engineering review and the applicable supplemental plans, etc to EPA 60 days prior to the generation of RINs.

RFS2 Workshop Presentations
On April 14 and 15, 2010, the National Petrochemical & Refiners Association (NPRA) and American Petroleum Institute (API) hosted an RFS2 implementation workshop where EPA provided detailed presentations on the Renewable Fuel Standard Program (RFS2) Final Rule. The presentation materials are now available online. Questions raised in the workshop are included in EPA’s Q&A list.

RFS1 Questions and Answers
Questions and Answers on the Renewable Fuels Standards (PDF) (59 pp, 270K, EPA420-F-08-006, April 2008). This document contains all previous versions' questions and answers for RFS1.
RFS1 Compliance Tools
EPA created two tools to assist RFS1 reporting parties. The first tool, RFS1 Report Checker, will help reporting parties identify and fix common reporting errors prior to report submission. The second tool, RIN Inventory, will help reporting parties keep track of quarterly purchases, sales and retirements to prepare for the RFS0100 report. EPA designed these tools in an effort to reduce the number of resubmittals EPA receives for RFS1 Reports.
