About Tim

Tim’s clients rely on him for strategic environmental permitting assistance, the defense of environmental enforcement actions and assistance with the environmental aspects of major transactions. His clients report in Chambers USA that “he really gets issues and is commercially minded” and 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 “great business acumen and amazing negotiation skills” (2009); and as capable of delivering “practical, cost-effective solutions for his clients” (2011).

He has overseen environmental compliance audits involving thousands of locations, handled hundreds of environmental audit disclosures and pioneered the development and use of U.S. EPA’s audit policy for new owners. Clients also note in Chambers USA that Tim is “fantastic, detailed and very strong with management systems.”

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.’

Environmental Auditing and Audit Disclosure in a New Era

May 2, 2017

Tim Wilkins discusses what changes in the country’s regulatory direction and approach to enforcement mean for environmental compliance auditing programs and audit disclosure under EPA and State audit policies.

Federal Court Sets Timeline for EPA to Reconsider Regulation of Oil and Gas Waste Under RCRA

January 17, 2017
Energy Legal Blog®

In yet another example of the U.S. Environmental Protection Agency (EPA’s) “sue and settle” approach to regulation, in late December 2016, EPA entered into a Consent Decree with an environmental group and agreed to reconsider the Agency’s current treatment of oil and gas...

Wilkins Publishes Critique of Expansive TCEQ Water Code Jurisdiction

May 11, 2016

In a recent article for the Texas Environmental Law Journal, I explore TCEQ’s view that the management of wastewaters or other industrial wastes “adjacent to water in the state” – construed expansively as (a) any location anywhere above groundwater or (b) anywhere waste may be “disposed of” via evaporation – requires a “Texas Land Application Permit” under the Water Code, above and beyond obtaining a Registration under TCEQ’s waste program. Under TCEQ’s interpretation, surface impoundments, evaporation ponds, on-site waste storage and disposal units, enclosed cleaning operations, sumps, and...

Major Air Enforcement Action Against New Plant Owner Suggests the Value of EPA's "New Owner Audit Policy"

May 21, 2015

A new $1.3 million Clean Air Act penalty action by U.S. EPA and the Michigan Department of Environmental Quality against AK Steel Corporation has received significant public and media attention this week. The proposed consent decree, filed with the court and opened for public comment on May 19th, includes significant cash penalties and supplemental environmental project requirements, along with burdensome obligations to establish an environmental management system, perform third party audits, and install costly new pollution controls. Less often mentioned in this week's stories about the...

9th Circuit Appeals Court: Clean Air Act Permits Must Address Latest EPA Requirements

August 13, 2014

On August 12, 2014, the 9th Circuit Court of Appeals overturned a Prevention of Significant Deterioration (PSD) permit issued under the Clean Air Act (CAA) by EPA to the Avenal Power Center. Sierra Club v. EPA, No. 11-73342 (9th Cir. Aug. 12, 2014). The PSD permit authorized the construction of a 600 MW natural gas-fired plant located in California's San Joaquin Valley. The plant was required to install state-of-the-art pollution controls for all traditionally regulated pollutants, such as nitrogen oxides, particulate matter, and carbon monoxide. The Court vacated the PSD permit because it...

Texas Greenhouse Gas Regulations Go Into Effect

April 22, 2014

On April 17, the Texas Commission on Environmental Quality's new greenhouse gas (GHG) regulations became effective, establishing the framework for a new GHG permitting program at TCEQ, which the agency hopes to begin implementing in the summer of 2014. Before this can happen, EPA must officially approve the rules and also rescind the Federal Implementation Plan under which it currently regulates GHGs in Texas. The rules have immediate implications for a variety of facilities, however. Whereas the changes to the PSD program only involve new or modified facilities, the Title V aspects of the...

Spill Prevention under the Proposed Waters of the United States Rule

April 4, 2014

We've blogged about the scope of EPA's proposed Waters of the United States rule and whether it provides any additional clarity to the current regulatory scheme. With this post, we'll start to outline some direct potential impacts on different segments of industry. Today, we briefly examine what an expanded regulatory scope of waters could mean for industries required to comply with the Spill Prevention, Control, and Countermeasure (SPCC) Rule under the Oil Pollution Act and the Clean Water Act. The SPCC Rule applies to most types of facilities with an aboveground oil storage capacity greater...

Texas One Step Closer to Obtaining Authority to Issue GHG Air Permits

March 31, 2014

As anticipated, on March 26, 2014, the Texas Commission on Environmental Quality (TCEQ) adopted rules to implement House Bill 788, which required the Commission to establish greenhouse gas (GHG) emissions rules. The new rules will become effective on April 17, 2014. This action is one more step in the process of transitioning GHG Prevention of Significant Deterioration (PSD) permitting authority from EPA to TCEQ. These regulations come on the heels of EPA publishing a proposal to approve the Texas GHG PSD revisions to the Texas State Implementation Plan (SIP) in 79 Fed. Reg. 9,123 (Feb. 18,...

EPA Proposes TCEQ Take Over GHG Permitting in Texas

February 7, 2014

On Tuesday, February 4, 2014, EPA issued a pre-publication copy of a proposed rule that if adopted would transfer greenhouse gas (GHG) permitting in Texas from EPA Region 6 to the Texas Commission on Environmental Quality (TCEQ). The proposed rule has yet to be published in the Federal Register. When it is published, the public will have 30 days to comment on the proposed rule. EPA must review and respond to those comments before it can adopt a final rule that would transfer authority to TCEQ. EPA is proposing to approve portions of various State Implementation Plan (SIP) revisions to the...

EPA adopts new standard for conducting All Appropriate Inquiries

December 30, 2013

In a rule published on December 30, 2013 and effective immediately upon publication, EPA formally adopts a new standard for conducting All Appropriate Inquiries (AAI) at potentially contaminated sites. 78 Fed. Reg. 79319. The AAI rule outlines steps for potential property purchasers to take to claim a limitation on CERCLA liability connected to purchased property. 40 CFR Part 312. EPA allows purchasers to use the applicable ASTM standard for Phase I Environmental Site Assessments to satisfy their obligations under the AAI rule. In this rule, EPA incorporates new ASTM International Standard...

Texas Greenhouse Gas Rules: Upcoming Hearing and End of Comment Period

December 2, 2013

As we discussed in an October post , the Texas Commission on Environmental Quality (TCEQ) has proposed rules to create a greenhouse gas (GHG) permitting program for the state of Texas and take over permitting authority from the U.S. Environmental Protection Agency (EPA). Because it hopes to make the transition as quickly as possible, TCEQ is using a streamlined public participation process, which is soon coming to an end. At 2:00 pm on December 5th, TCEQ will hold its only public hearing on the proposal (see notice here ). TCEQ will then continue to accept written comments on the rules...

Texas Regulators Take First Steps to Acquire Greenhouse Gas Permitting Authority

October 10, 2013

On October 4th, the Texas Commission on Environmental Quality (TCEQ) released a preliminary draft of a proposal to establish greenhouse gas (GHG) permitting regulations for the state of Texas. This action kicks off what is likely to be a lively discussion between stakeholders and regulators over the design of Texas's GHG permitting program. But it represents a first step toward an important change from the status quo. For almost three years now, Texas companies have been subject to two different permitting authorities for air permits: the U.S. Environmental Protection Agency (EPA) issues GHG...

EPA Issues New Final Greenhouse Gas Clean Air Act Permit

June 12, 2013

On June 10, 2013, EPA issued a final greenhouse gas (GHG) Prevention of Significant Deterioration (PSD) permit to PL Propylene, LLC for construction of combustion turbines, heaters, waste heat boilers, and a flare at an existing propane dehydrogenation plant in Houston, Texas. Currently, EPA Region 6 has 69 permit applications listed on their docket. Of those applications, EPA has finalized 15 PSD permits. Processing time from initial application to final permit varies, but the time line has ranged between six months to over 14 months with some applications having been pending for longer than...
