Environmental Advances at Koppers RUPS and CMC

Regulatory Compliance

Koppers aggressively monitors and adheres to policy language and regulatory requirements on protecting our employees, neighbors and the environment potentially affected by our operations. The PC, RUPS and CMC businesses all operate under stringent regulations and guidelines of environmental and safety regulatory agencies at the federal, state, and municipal levels around the world. In addition to regulatory requirements, Koppers facilities comply with voluntary industry standards pertaining to employee safety, process safety management, environmental protection, and security.

Treating Wood for Railroad Ties

The wood treatment industry began about 100 years ago, as railroads realized they needed to take a long-term view of their industry. Preserving rail ties became an obvious priority, so they knew they had to use treated wood. In part because treatment extends the life of wood converted into ties, and in part due to careful land management, today in the U.S., wood is actually grown faster than it’s being used, creating a surplus of this resource.

Ride-Tight® Rail Car Containment Program

To ensure all rail car shipments of liquid products remain free of leaks and the subsequent environmental impact, Koppers engaged and collaborated with the American Association of Railroads (AAR) and VSP Technologies to implement a comprehensive training, inspection and maintenance program called Ride Tight®. The program has been implemented at all Koppers facilities and contracted railcar service providers in North America, and helps ensure enhanced railcar performance related to safety and protection of the environment.

As a result of our participation in Ride-Tight® Koppers was honored in 2015 and 2016 with AAR’s Grand-Slam Award, the most prestigious award attainable for railroad hazardous material shipping.
