Catalyst works closely with our clients and public agencies to prepare environmental constraints analyses, National Environmental Policy Act (and state equivalents) analyses, customized planning and compliance documents. We are also recognized experts in contamination assessment and cleanup and vapor risk mitigation with a focus on achieving facility construction and occupancy on schedule.
Our team of certified land use planners and project managers are experts in California Environmental Quality Act and National Environmental Policy Act analyses and environmental permitting We work with our clients and regulatory agencies to determine the appropriate level of analysis, develop an accurate project description and purpose-and-need statement, identify a reasonable range of alternatives, and analyze potential environmental impacts to produce defensible compliance documents.
The Catalyst risk and liability practice includes experienced engineers and geologists who have prepared and implemented remedial action plans for clean-up of contaminated areas. We work with clients and regulators to ensure that lands are suitable for proposed development and receive appropriate regulatory closure. Our team works on projects cradle-to-grave, from the initial Phase I environmental site assessment, to site sampling, to development of the remedial action plan, through oversight of the construction contractor during site remediation and confirmation sampling to receive the closure certificate.

​​​​​​​We offer the full suite of technical services and for those projects that require expertise in a specific technical discipline, Catalyst maintains partnership agreements with premier firms in air quality, cultural resources, and biological resources. While we offer a wide range of professional services, we also practice the concept that the environmental consulting community is a tool box and through teaming arrangements, Catalyst can provide the best team for the job.

We regularly examine land use compatibility of various activities within existing regulatory frameworks and work with our clients to develop materials to assist in community outreach related to compatibility issues. Having worked for a diverse client base that includes agencies, utilities, companies, and tribes, our consultants are practiced in both the applicant-side and third-party formats. Recently, we assisted PacifiCorp with permitting an array of communication towers across Oregon to comply with NERC’s service reliability standards.
