Maureen is a seasoned environmental attorney, regulatory specialist, and litigator in Tonkon Torp’s Environmental & Natural Resources Practice Group and Business Department.

Maureen’s practice is focused on representing clients facing environmental issues related to regulatory compliance, site contamination, and business transactions. Clients value Maureen’s deep understanding of complex environmental challenges and her ability to provide creative solutions for the best possible outcome. She is adept at approaching her practice through a combination of science and law. No matter what issue her clients face, Maureen puts their best interests first and provides practical advice and counsel all along the way.

Maureen has significant legal and technical experience remediating contaminated property and managing all stages of environmental litigation.

She has experience obtaining stormwater, wastewater, and air emissions permits, negotiating settlements and resolving non-compliance issues with regulatory agencies, and transferring permits to new entities following change in ownership.

When buying or selling a piece of potentially contaminated property, understanding environmental risk is key to avoiding major issues down the road. Maureen works with environmental consultants and transactional attorneys to identify and appropriately shift environmental risk so that her clients can close their business transactions with peace of mind.

When not in the office, Maureen can be found skiing in the winter, paddle boarding in the summer, and hiking year-round – often in the company of her two children.

D.C. Circuit Court Invalidates NEPA Rules

By Maureen Bayer – A federal court in Washington, D.C. recently ruled that the White House Council on Environmental Quality (CEQ) does not have authority to issue environmental regulations under the National Environmental Policy Act of 1969, commonly known as NEPA. This decision follows the Supreme Court’s recent case overruling long-standing precedent known as the “Chevron rule,” deferring to government agencies in their particular areas of expertise.
