Molly counsels clients on virtually every kind of environmental matter and represents them before various agencies and in federal and state courts.

In the enforcement area, she has litigated and negotiated settlements for clients under the Clean Water Act, Clean Air Act, Resource Conservation and Recovery Act, and their state analogs, as well as Superfund. Molly has counseled on audit issues, under both the state audit law and federal policy. She also has both resolved and tried disputes regarding water supply and utility issues.

With regard to air and solid waste, Molly has handled a variety of contested cases, including incinerator and BIF air and hazardous waste permitting. She represents clients in State Implementation Plan (SIP) issues as well. On both a state and federal level, Molly has assisted clients in rulemaking petitions and in preparing comments on agency rules. She also has assisted clients in bringing litigation to challenge environmental legislation and rules. Molly has testified before the United States and Texas Senates, and has served as a testifying expert on environmental issues in a number of cases.
