Tim Martin

Tim has been working on dispersion modeling and meteorological analyses, emission inventories, regulatory analyses, air quality permitting, and agency negotiations since 1998. He provides air quality consulting services to industries spanning oil and gas exploration and production, mining, power generation, municipal utilities, and industrial manufacturing, to name a few. His projects are complex and include Prevention of Significant Deterioration permitting efforts, reports, cost estimates and budgeting, and technical work.

The technical work on permitting projects has included regulatory reviews, emission inventories, BACT/control technology analyses, dispersion modeling, and health risk assessments. He has conducted impact analyses using dispersion modeling for demonstration of full facility compliance.

Tim’s insight into the regulatory landscape is borne out of his experience with the Arizona Department of Environmental Quality, where he was the chief permit modeler and a part-time permit engineer. He’s also worked as a corporate environmental engineer for a leading manufacturer of fiberglass insulation and roofing products.

Mark Schaaf, PhD

Mark has worked on scientific studies, regulatory analyses, and program management since 1984. At Air Sciences his work has involved the mostly dry Owens Lake in California. He has been supporting the Los Angeles Department of Water and Power and its Owens Lake Dust Mitigation Project since 1997. He also spearheads Air Sciences’ Owens Lake Science, Technology, and Regulatory contract valued at more than 30 million dollars and in place for over a decade. Wide-scale projects of this scope are nothing new to Mark. Prior to Owens Lake, he was the program manager on a multi-million dollar contract to provide nationwide air quality services to the USDA Forest Service and other federal land management agencies.

A leading air quality expert, Mark was the principal investigator on dozens of air quality impact reports and models. He’s also authored scientific publications on fugitive dust emissions monitoring and modeling, wildland fire behavior and smoke emissions modeling, landscape-scale fire effects tradeoff analysis, and micrometeorology. Earlier in his career his work was more hands on, serving as a firefighter, timber cruiser, and sawmill worker around Oregon.
