Thomas A. Bloomfield  linkedin_20x20

Thomas A. Bloomfield represents public and private clients on major environmental litigation, counseling, administrative law, and policy matters.

He is skilled at bringing together parties with diverse interests to solve complex problems in a manner that best achieves the objectives of the stakeholders and avoids unnecessary litigation and protracted disagreements. He is adept at understanding technical issues and efficiently integrating that information to best represent the legal interests of his clients. Tom also maintains an environmental law blog,

Tom's practice covers a wide range of cutting-edge technical and substantive areas, including air quality matters, climate change, energy policy, oil and gas regulation, toxic tort litigation, CERCLA litigation, remediation of mine sites, energy policy, emerging contaminant litigation, environmental cost cap insurance, water rights, chemical fingerprinting, sediment contamination, mining law, vapor intrusion, computer modeling, condemnation, risk-based closures, environmental audits, land use planning, CEQA, NEPA, and post-closure of RCRA units.

Tom has played a pivotal role in several of the most significant air quality rulemakings in Colorado over the past few years, including the first statewide rules to control methane from oil and gas operations; the Clean Air Clean Jobs Act rulemakings (the groundbreaking program that integrated energy planning and environmental regulation to address regional haze, climate change and public health) and the Colorado Regional Haze State Implementation Plan. Tom also advises clients on the proposed US EPA Clean Power Plan regulations.

Tom has an extensive Superfund litigation practice, including cases involving mine sites, perchlorate and other contamination, as well as toxic tort defense. He has represented the County of San Bernardino, mining companies and other industrial clients, the State of California and the California Department of General Services, and various environmental agencies and boards.

Prior to opening the Colorado office for the firm, he served as an Assistant Regional Counsel at the United States Environmental Protection Agency (EPA) in San Francisco, where he resolved major aspects of some of the most significant and high profile cases in the region. Tom was the principal architect and lead federal negotiator for the Iron Mountain Mine settlement. The settlement, one of the largest and most innovative in the history of the Superfund program, combines environmental cost overrun insurance, a finite risk policy, indemnities, corporate guarantees, bonds, and other insurance and finance tools to secure perpetual treatment of one of the country's worst environmental pollution problems.

Through his work at the EPA, Tom became recognized as a leading national expert on financial assurance issues, environmental insurance, fixed-price contractual arrangements and alternative financing approaches for public projects. Tom regularly advised EPA regions across the country on legal and policy issues concerning the use of new environmental insurance tools and the use of so called "Superfund Companies" for CERCLA settlements and Brownfields developments. He also helped formulate national EPA and DOJ policy on these issues.

Tom is a frequent public speaker on environmental, energy and policy matters.
