RFS Consulting, Inc. (RFS) is a multi-media environmental engineering and consulting firm, originating in Tulsa, Oklahoma and serving industry across the country since 1986. Though the firm assists a diverse client base in addressing a number of environmental concerns, our specialty has become air quality issues for predominantly the Oil and Gas Industry, followed by foundries, metal fabricators, and surface coaters. Air quality services include permitting (minor, major, and PSD), recordkeeping, reporting, emission inventories for criteria pollutants, hazardous air pollutants, and greenhouse gas emissions, compliance assistance, dispersion modeling, risk assessments, and data management systems. To support our services and client needs, RFS has developed software called REMIS, which is a comprehensive, robust relational data management system which serves as a tool to assist in organizing facility and equipment information, performing scientific and engineering calculations, and generating emission reports. The system utilizes physical design and operating data, manufacturer emission factors, AP-42 factors, analytical data and more to aid in completing emission inventories for facilities located across the country.
