Being co-located in the San Francisco Bay Area and Washington, DC offices allows her to serve clients nationally and in California, a jurisdiction that is frequently at the forefront of environmental regulation. Her practice focuses on three primary areas: government and regulatory affairs, compliance counseling and enforcement defense, and environmental litigation.

She was selected by the US Environmental Protection Agency (EPA) to serve on numerous committees and stakeholder groups to develop regulations such as the New Source Review, NESHAP, and Title V operating permit regulations.
In addition, Shannon was deeply involved on behalf of clients in the development of EPA's Risk Management Program (RMP) regulations, which were issued under the Clean Air Act Amendments of 1990, and also involved the simultaneously enacted Process Safety Management (PSM) program regulations by the Occupational Safety & Health Administration. In her work as counsel for General Electric, Shannon achieved numerous regulatory changes in the RMP rules between proposal and promulgation and subsequently challenged EPA's regulations, resulting in a successful settlement. She was a lead counsel advising on implementation of RMP at General Electric (which at the time included GE Plastics) and was part of the team that achieved a record number of voluntary protection program (VPP) designations for the company. She participated in management reviews of implementation of these requirements and was the lead liaison to GE Aircraft Engines on these issues during her tenure at the company. Shannon also has advised companies on compliance obligations under the General Duty Clause, RMP and compliance certifications for the same.

From 1992 through 2000, Shannon was a vital participant in many EPA stakeholder discussion roundtables on New Source Review as EPA's reform process for those regulations proceeded. In June 2004, Shannon was selected by EPA to serve as one of six industry representatives and one of 18 outside members of the Title V Task Force under the Permits, New Source Review and Toxics Subcommittee of the Clean Air Act Advisory Committee, a group charged with evaluating the state of the Clean Air Act's Title V permitting program and making recommendations for improvement. In 2009, she participated on EPA's Greenhouse Gas BACT Workgroup, a sub-group of EPA's Clean Air Act Advisory Committee, which addressed the potential application of controls for greenhouse gases under the act.
