Her substantive expertise includes such areas as the federal Resource Conservation and Recovery Act (RCRA), the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), the federal Clean Air Act (CAA), the federal Clean Water Act (CWA), California’s Porter-Cologne Water Quality Control Act (Porter-Cologne), California’s Hazardous Waste Control Law, and the Global Warming Solutions Act of 2006 (AB 32). Ms. Hartman King handles matters before various federal and state administrative agencies, such as the United States Environmental Protection Agency and its regional offices, the California Air Resources Board (CARB), the State Water Resources Control Board, the regional water quality control boards, local air quality management and air pollution control districts, and the California Department of Toxic Substances Control, among others. Ms. Hartman King also has deep expertise in weights and measures laws. Representing clients with operations throughout the United States, she provides compliance advice, develops and presents employee training programs and defends administrative, civil and criminal enforcement actions.

Ms. Hartman King is well known for developing strong relationships with her clients. She prides herself in partnering with those she represents to understand them and their business. She provides sophisticated and strategic advice in “plain English” and helps clients navigate complex areas of law to achieve their goals in the most effective and cost-efficient manner. She is proud to represent a wide range of clients, including individuals, municipalities, small companies and Fortune 100 entities with operations throughout the United States and in multiple other countries. She has particular expertise representing retailers, manufacturers, real estate developers, property owners, the auto industry, and industrial, chemical, energy and petroleum facilities. She has served as outside environmental and regulatory counsel to one of the largest grocers in the United States for many years and represents multiple online product and service providers with operations throughout the country.

Before launching Hartman King PC, Ms. Hartman King developed her expertise as a member of the environmental practice groups at certain of the largest and most well-respected law firms in California. She also was an office Managing Partner and the environmental practice group leader at a prestigious big firm spin-off located in the Sacramento area.

Ms. Hartman King also has served at the highest level of state government, as Deputy Legal Affairs Secretary to California Governor Gray Davis. She provided legal advice and assistance to the Governor and his staff on a host of issues facing the state. She oversaw litigation challenging various decisions made by the Governor, including several high-profile cases, served as the primary liaison in the Governor’s Legal Affairs Office for several state agencies and departments, and was responsible for reviewing significant legal and litigation issues on behalf of the Governor’s Office.

In 2010, Ms. Hartman King was appointed by the California State Water Resources Control Board to serve on the Underground Storage Tank (UST) Cleanup Program Task Force. In that role, she worked closely with selected leaders in the environmental field to advise the Water Board on strategies for improving the UST Cleanup Program. She collaboratively devised, negotiated and prepared proposed resolutions for the Water Board that clarified and streamlined the Cleanup Program. The Water Board adopted several of these resolutions, thereby affecting the way UST sites are investigated, remediated, and ultimately closed.
Ms. Hartman King has been a long-time member of the National Conference on Weights and Measures (NCWM) and, in 2019, she was asked to join NCWM’s Packaging and Labeling Subcommittee. In this position, she reviews and provides input on proposed regulatory revisions that have the potential to affect a wide range of product manufacturers, distributors, packers and sellers nationwide.
