    Air Quality Permitting

    When constructing a new industrial facility, expanding production, or modifying operations, facilities may be subject to air quality permitting requirements. Sources must be designed, constructed, and operated to comply with all applicable air quality regulations. Air quality requirements exist within a range of regulatory programs, including local/state and federal programs such as New Source Review (NSR) and Title V operating permit programs. Technical requirements such as emissions quantification, control technology evaluations, air quality analysis (including dispersion modeling), ambient air and meteorological monitoring, emission standards applicability, and compliance assurance are all components of these regulations.


    WET can assist with all phases of the air permitting process, assuring accurate, timely permit applications that are focused on maximum operational flexibility. Expert negotiations with regulatory agencies simplify the permitting process.



    Emission Inventories

    Many air quality permits require a facility-wide inventory of all air emission sources. An accurate accounting of emissions is also necessary for accurate calculation of annual permit fees to regulatory agencies. In addition to common point sources, facilities often have emission sources that are more difficult to identify and quantify, such as material storage piles, material handling operations, surface coating operations, and dust from roadways and parking lots. Use of appropriate emission factors and rates is key for developing permitting strategies and determining applicable regulations.
