Susan G.


Susan Lafferty advises clients on an array of energy and environmental issues impacting the petroleum, biofuels and energy trading industries. Susan’s extensive practice covers regulatory, commercial and policy issues related to the Renewable Fuel Standard (RFS), renewable identification number (RIN) trading, state low carbon fuel standards (LCFS), gasoline and ultra-low sulfur diesel (ULSD) requirements, and shipping all types of commodities by rail, vessel or truck.  She also advises clients on daily trading and commercial matters as well as significant enforcement actions.

Susan represented more than 15 companies in RIN enforcement proceedings that led to the implementation of the EPA’s Interim Enforcement Policies and Quality Assurance Program, as well as refiners and importers facing enforcement actions under the broader mobile source program. Susan led the representation of a renewable fuel trader that EPA alleged exported renewable fuel without retiring RINs. Susan is a sought-after speaker on regulatory and agency actions, is quoted frequently on fuels issues, and co-authored a white paper for the Bipartisan Policy Center entitled “Options for Reforming the Renewable Fuel Standard.” 

In addition, Susan works with clients to develop risk management and mitigation tools to address potential spills or releases that may occur when transporting and storing products like crude oil, distillates, liquefied natural gas and coal.  She has helped her clients navigate crude-by-rail matters, including the new regulatory requirements and responses to some of the largest accidents involving crude oil shipped by rail.  To this end, as a member of Eversheds Sutherland (US)'s Crisis Management team, Susan helps clients navigate crises and develop legal response strategies tailored to each specific situation.
