Jan Jacobson | Principal Regulatory Specialist
Co-owner and Principal, Jan Jacobson is a geologist with over 30 years of experience in the environmental services industry working on remediation, restoration, and permitting projects throughout the Western US. Her technical background, combined with regulatory expertise and agency relationships, provides a unique skill set for resolving and expediting complex environmental projects. She founded Jacobson Environmental (JE) in 2003 and co-founded JJ&A in 2008.
A contemporary pioneer within the industry, Jan brought forth the concepts of Regulatory Feasibility Studies and Project Driven Teams. The basis of the Regulatory Feasibility Study concept is that the opportunities for the most significant cost savings are associated with the regulatory strategy more times than with the technical approach. Project Driven Teams reflect the JJ&A approach of identifying and working with the best resources for the project, versus the traditional approach of forming a project team solely from within the confines of a prime contractor resource base.
Jan believes that the regulators are a key part of the project team’s success and has demonstrated expertise and successes working with various agencies within environmental regulatory frameworks including: CWA and state Water Law (Water Code), CEQA, RCRA and state Hazardous Waste Control Law (Health and Safety Code), CERCLA (including NCP compliance for cost recovery), state superfund, voluntary cleanup programs, and state natural resources code and regulations.
