Air Quality Management
DPRA offers a highly practical set of air quality services including dispersion modeling, compliance, inventory reporting, permitting, and regulatory liaise for commercial and industrial organizations. Air emissions inventory, control, and permitting is a challenging regulatory undertaking for most facilities. Even facilities with seemingly minimal air emission impacts are often required to assess the need for an air permit within the regulatory framework of their state and local authorities.
DPRA is experienced in working with a wide array of industrial facilities utilizing air quality models that most state air program staff uses to predict emissions from new facilities and facility modifications. Through the use of appropriate air quality models, DPRA mathematically describes pollution transport, dispersion, and related processes in the atmosphere and estimates the ambient pollutant concentration and deposition at many locations based on emissions, meteorology, topography, and aerodynamic turbulence induced by buildings and other site features.
DPRA’s experienced compliance auditors conduct multi-media compliance audits at industrial facilities across the country to identify air emissions sources and determine if actual or potential emissions of air pollutants at the facilities trigger federal, state, or local permitting requirements. As part of the audit process, DPRA reviews the regulatory thresholds for air emissions for the area where the facility is located, conducts site visits to identify air emissions units and obtain operational data, and prepares emission inventory reports, including PTE calculations. Then we provide the back calculations, process drawings, and completed application forms to the appropriate regulatory authorities to obtain the permit or permit modification.
Although air programs within many states are streamlined to reduce the permitting burden for facilities that fall beneath the Federal permitting thresholds, the permitting of your facility, from construction to operation, can be a daunting undertaking. DPRA is experienced in preparing and shepherding these permits through the state regulatory process in a timely fashion.
Please see our other service area descriptions for more information on service areas that support our air quality management practice including: plan preparation, training, pollution prevention, and regulatory reporting.
Our air permitting experience includes the following activities:
- Facility-wide emissions inventories for various industries;
- Construction and operating permit applications;
- Permit modifications for addition of air pollution control equipment;
- Permit modifications for changes in facility processes;
- Annual emissions inventories for permitted facilities;
- Air emissions recordkeeping in compliance with regulations/permits; and
- Monitoring and maintenance programs for air pollution control equipment.
