Patrick D. Traylor

Partner, Vinson & Elkins

With the combined experience of being one of the highest-ranking environmental enforcement attorneys in the federal government and over twenty years in private practice, Patrick Traylor has developed a unique skill set in the areas of civil environmental litigation, complex environmental permitting, and environmental enforcement investigations that makes him a trusted advisor to clients worldwide.

During his tenure at the EPA, Patrick supervised the agency’s nationwide Clean Air Act (CAA) civil enforcement docket. He was also integrally involved in the development of every significant enforcement policy and represented OECA in reviewing all CAA regulations and guidance issued by the EPA. Patrick leverages this insight into the EPA’s CAA enforcement process to effectively and efficiently represent clients facing enforcement investigations and actions.

Prior to his service at the EPA, Patrick spent the first two decades of his legal career at a Global Top Ten law firm where clients relied on him to represent them in a variety of environmental enforcement cases, internal compliance investigations, and complex permitting matters.
