About Eric Waeckerlin

Eric Waeckerlin is a trusted advisor to leading energy, oil and gas, mining, manufacturing, and industrial companies on their most complex and consequential environmental and natural resources matters. He counsels clients through high-stakes regulatory, permitting, enforcement, and policy challenges at the intersection of major project development, air quality, and climate strategy, with a practice designed to support executive decision-making and enterprise-level risk management.

Eric is nationally recognized for his deep skills navigating the federal Clean Air Act (CAA) and its state analogues, and he routinely advises on permitting, compliance, and enforcement matters affecting large-scale conventional and low-carbon energy projects. His experience spans the full lifecycle of major projects-from early siting and permitting strategy through construction, operation, and defense of agency actions-allowing clients to move critical projects forward while managing regulatory, reputational, and financial risk. In addition to the CAA, Eric has substantial experience under the Resource Conservation and Recovery Act (RCRA), Clean Water Act (CWA), Safe Drinking Water Act (SDWA), Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and the National Environmental Policy Act (NEPA).

As energy markets evolve, Eric has been at the forefront of advising clients on climate and decarbonization strategies. He counsels companies on domestic and international climate and methane policy, including carbon capture and other CO management regimes, emissions reduction and offset strategies, and participation in carbon and greenhouse gas markets. His work helps clients integrate highly complex regulatory compliance with broader sustainability, investment, and corporate strategy objectives.

In high-stakes litigation and regulatory challenges, Eric has served as lead counsel for national oil and gas trade associations in challenges to federal regulations and has successfully defended oil and natural gas companies in numerous multimillion-dollar air quality enforcement actions brought by the EPA and state agencies. Clients value his ability to combine technical regulatory knowledge with strategic judgment, making him a go-to counselor for executives and management teams navigating the legal risks shaping the future of energy.

Lawyers.com Client Reviews

Martindale-Hubbell® Client Review Ratings™ display reviews submitted by individuals who have either hired or consulted the lawyers or law firms.

The Client Review Rating score is determined through the aggregation of validated responses. People who submit reviews are either individuals who consulted with the lawyer/law firm or who hired the lawyer/law firm and want to share their experience of that lawyer or law firm with other potential clients. Reviewers can be anyone who consults or hires a lawyer including in-house counsel, corporate executives, small business owners, and private individuals.

Martindale-Hubbell validates that a reviewer is a person with a valid email address. As part of the review process, respondents must affirm that they have had an initial consultation, are currently a client or have been a client of the lawyer or law firm identified, although Martindale-Hubbell cannot confirm the lawyer/client relationship as it is often confidential. The content of the responses is entirely from reviewers.

Prior results do not guarantee a similar outcome and Martindale-Hubbell accepts no responsibility for the content or accuracy of any review. For more information on Martindale-Hubbell Client Review Ratings, please visit our Client Review Page

Martindale Peer Reviews

Martindale-Hubbell® Peer Review Ratings™ are the gold standard in attorney ratings, and have been for more than a century. These ratings indicate attorneys who are widely respected by their peers for their ethical standards and legal expertise in a specific area of practice.

The Martindale-Hubbell Peer Review Ratings process is the gold standard due to its objectivity and comprehensiveness. Lawyers solicited for peer reviews include both those selected by the attorney being reviewed and lawyers independently selected by Martindale-Hubbell. All reviewers are verified as attorneys through Martindale-Hubbell’s extensive attorney database. Only attorneys practicing at least three years and receiving a sufficient number of reviews from non-affiliated attorneys are eligible to receive a Rating.

What are the different Martindale-Hubbell Peer Review Ratings?*

• AV Preeminent®: The highest peer rating standard. This rating signifies that a large number of the lawyer’s peers rank him or her at the highest level of professional excellence for their legal knowledge, communication skills and ethical standards.

• Distinguished: An excellent rating for a lawyer with some experience. This rating indicates the attorney is widely respected by their peers for high professional achievement and ethical standards.

• Notable: This rating indicates that the lawyer has been recognized by a large number of their peers for strong ethical standards.

Lawyers who have received peer reviews after 2009 will display more detailed information, including practice areas, summary ratings, detailed numeric ratings and written feedback (if available). Details for individual reviews received before 2009 are not displayed.

Attorneys that receive reviews from their peers, but not a sufficient number to establish a Martindale-Hubbell Peer Review Rating, will have those reviews display on our websites.
