Air Sciences Inc was founded in the Denver-metro area in 1980 with the purpose of providing superior air pollution consulting services. In its first 10 years Air Sciences Inc attained this goal and presently enjoys a unique reputation as a firm that provides both industry and government a high quality service in air quality consulting. Our future is focused on emerging disciplines in the air quality arena driven by new air quality standards and regional haze regulations. Air Sciences Inc remains an employee-owned firm. With offices in Golden, Colorado ( 14 miles west of downtown Denver ) and downtown Portland, Oregon, we maintain excellent access to business activity and government agencies throughout the west. We've worked hard to keep our "back office" small and efficient and every employee is equipped to contribute to project work for clients. The project managers who do the work also do the sales and marketing for the company so useful, practical information about solving problems starts with your first phone call or email. While our telecommunications and digital networking resources are state-of-the-art, Air Sciences still provides personal attention to our clients. We know that the answers to today's air quality challenges are found using the technical horsepower and regulatory know-how of our professional staff and we continue to invest in the professional development and education of our employees. Our complete in-house air quality services include dispersion modeling, visibility modeling, emission inventories, monitoring, permitting, engineering services, and air quality impact assessment ( EIS and EA ). Our staff is comprised of recognized experts in fire emissions modeling, fire effects model development and application, fugitive dust modeling and monitoring, application of Geographic Information Science ( GIS ) to emission inventories, and tribal air program development. In addition, we specialize in rule applicability analyses, compliance assessment and planning, and economic analysis and conceptual engineering of air pollution control systems. Throughout the past 28 years, Air Sciences Inc has worked with industry and government. Industry sectors have included minerals extraction, minerals refining, power production, natural gas processing, chemical manufacturing, painting processes, and pesticide formulation. Government work has included fire emissions modeling and fire effects model development and application for federal land managers and studies of dust movement and modeling for EPA. Air Sciences' personnel have also provided technical air quality services, including air program development, to over 20 Indian tribes. Our experience includes working in all aspects of de-centralized air pollution planning, including emission inventory development for communities, Tribes, States, and Regional Planning Organizations ( RPO ). Our projects are located throughout the United States. We also have international experience in Latin America, Europe, and Southeast Asia.
