Community Information about the Union Pacific Site in Houston's Fifth Ward

The U.S. Environmental Protection Agency is conducting activities under two EPA authorities, the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) including permitting, enforcement, investigation, and cleanup.

For up-to-date information on the CERCLA investigation (also known as Superfund) and ongoing community engagement, please visit our Fifth Ward/Kashmere Gardens UPRR Hubsite.

The Union Pacific Railroad Houston Wood Preserving Works site (UPRR) is located adjacent to the Kashmere Gardens community within the Fifth Ward in the City of Houston. Formerly owned and operated by Southern Pacific Railroad, the site ceased operating as a wood preserving facility in 1984.

UPRR is conducting ongoing investigation and cleanup of the site under a Texas Commission on Environmental Quality (TCEQ) Industrial and Hazardous Waste Permit under its approved RCRA program. Additionally, EPA is overseeing an investigation under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) authority at this site and in the surrounding neighborhood.
