About Tim

Tim’s clients rely on him for the defense of environmental enforcement actions and assistance with the environmental aspects of major transactions and project development matters, including siting and permitting. Tim has also overseen environmental compliance audits involving thousands of locations, handled hundreds of environmental audit disclosures and pioneered the development and use of US EPA’s audit policy for new owners. Although he undertakes matters in all environmental media, Tim has special depth in issues involving hazardous waste.

His clients report in Chambers USA that “he’s the premier lawyer in Texas," "the best on all environmental matters,” and “the rare outside counsel who combines subject-matter expertise with outstanding commercial judgment” (2023). They have said that “one of Tim’s chief strengths is his ability to explain the law in a way that anyone can understand” (2019). They have also described him as “a very astute lawyer, liked for his quickness and thorough responses” (2007); as having “a good blend of scientific knowledge and legal acumen that helps navigate challenging regulatory issues” (2021); as having “great business acumen and amazing negotiation skills” (2009); and as capable of delivering “practical, cost-effective solutions for his clients” (2011). Tim was also recognized by Law360 as a 2023 Environmental MVP.

In addition to his duties at Bracewell, Tim periodically teaches the course in Corporate Environmental Law at The University of Texas School of Law. Before joining Bracewell, Tim was research assistant to Professor Laurence H. Tribe of Harvard Law School, editor-in-chief of the Harvard Environmental Law Review, and a judicial clerk for the Honorable Henry A. Politz, Chief Judge of the United States Court of Appeals for the Fifth Circuit.

The ‘phenomenal’ Timothy Wilkins is considered ‘an excellent, top-shelf lawyer who understands the technical complexities and regulations.’
