Katherine F. Waring specializes in transportation, environmental, and legislative matters. Ms. Waring’s scientific background as a geologist enables her to provide a nuanced and technical review of complex transactions. She participates in the drafting of comments for rulemakings, administrative adjudications before the Surface Transportation Board (“STB”), the filing of any necessary appeals, and she provides updates on legislative and regulatory issues.  She also works with consultants and engineers to evaluate rail access, to draft trackage agreements, assist with permitting, and to plan rail buildouts.

While attending law school, Ms. Waring worked full-time on Capitol Hill. Prior to joining Slover & Loftus she was a legislative assistant on the Transportation and Infrastructure Committee. Her Capitol Hill experience also included time on the Natural Resources Committee as a paid intern on the Water and Power Subcommittee and then as a Clerk with the Chief Counsel’s office.

Before working on Capitol Hill, Ms. Waring worked as a geologist for six years. She has her masters in geology and is a licensed professional geologist in the State of California. As a geologist she helped clients navigate the environmental permitting process, participated in the siting and design of production and monitoring wells, and oversaw the construction and installation of large municipal water wells.
