Tim Peckinpaugh's practice focuses on energy, environmental, and natural resource legislative and funding issues.
Mr. Peckinpaugh has represented clients for over thirty years in all aspects of energy policy, including nuclear (fission and fusion), hydroelectric, coal, oil and natural gas, electricity, as well as a variety of clean technology and energy efficiency issues. He also represents major international corporations and local communities on Department of Energy nuclear waste cleanup, nuclear security, and contracting issues. In addition, Mr. Peckinpaugh represents regional chambers of commerce and companies from the Pacific Northwest on appropriations, grant funding, energy, technology, natural resource, trade, agriculture, workforce, and economic development opportunities.
Mr. Peckinpaugh provides assistance on appropriations and legislative drafting, and counsels many of the firm's clients on campaign finance, lobbying, and governmental ethical issues. Finally, he is a previous chair of the firm's public policy group and currently manages the K&L Gates Political Action Committee, one of the largest law firm PACs in the country.
Mr. Peckinpaugh came to the firm in 1985 from Capitol Hill, where he had five year's experience as a professional staff aide to the House Science Committee, former U.S. Congressman Sid Morrison (R–WA), and the Republican Study Committee. While on the Hill, he focused on energy, natural resource, science, technology, and defense issues.
