About Trent M. Doyle

Trent Doyle advises clients on environmental, transportation, and risk management matters, including compliance with United States (U.S.) and international chemical control laws, hazardous materials regulations, and all aspects of the Toxic Substances Control Act (TSCA). The depth and breadth of Trent’s understanding of environmental and transportation laws enables him to support companies up and down the value chain on product stewardship and facility-based issues.

He counsels companies on product testing, classification, packaging, and labeling to address the requirements of the U.S. Department of Transportation (DOT) hazardous materials regulations and international counterparts (ICAO/IATA, IMDG Code, ADR, etc.). He secures government approvals, special permits, and letters of interpretation and represents shippers in investigations and enforcement cases involving the Pipeline and Hazardous Materials Safety Administration (PHMSA), the Federal Aviation Administration (FAA), and other modal administrations and agencies. Trent has extensive experience in advising companies on the transport of products ranging from bulk industrial chemicals to personal care products and lithium batteries. He also advises motor carrier clients on compliance with Federal Motor Carrier Safety Administration (FMCSA) regulations and state counterparts.

Trent advises businesses on their environmental compliance management and product stewardship programs. He helps companies prepare for agency inspections, respond to letters of investigation and data requests, and manage communications with regulatory authorities, customers, and other stakeholders. He conducts regulatory compliance audits and helps clients obtain relief under the U.S. Environmental Protection Agency's (EPA) Audit Policy and state audit/self-disclosure laws and policies.

Trent serves as counsel to multiple chemical industry trade associations, providing strategic legal advice on legislative, regulatory, and public policy issues.

Prior to practicing law, Trent worked as an environmental engineer and consultant and prepared numerous air permit applications, emission inventories, environmental impact statements, and compliance plans for a wide range of industrial facilities. He leverages this experience and technical background in working with a client’s business team/consultants to serve as a trusted legal advisor who can recommend practical solutions to pressing challenges.

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.
