Air Quality Management

Terranext's air quality professionals provide a broad range of state-of-the-art services tailored to each client's unique requirements. We perform feasibility studies for new construction and major modification projects to evaluate site suitability and engineering design alternatives. Terranext conducts all air quality and meteorological analyses; and prepare applications required to obtain state and federal air permits.


We have extensive experience utilizing the various industry and EPA air quality dispersion models, and are often called upon to modify these models for project-specific needs such as complex terrain and aerodynamic downwash. Specific modeling available includes:


  • Dispersion Modeling
  • Aerodynamic Downwash Analyses
  • Model Validation
  • GEP Stack Height Studies

Terranext will interface with design engineers in specifying and evaluating the most cost-effective designs of air pollution control systems which ensure compliance with regulations. We perform feasibility studies; and conceptual and preliminary design to select the final design approach. We design and manage field data collection efforts for pre- and post-operational monitoring of ambient air quality, meteorology, and source emissions.


We specialize in short-turnaround client-specific services, such as regulatory impact analyses required to resolve unique permitting problems, including:

  • Expert Testimony
  • Fugitive Emissions
  • Cooling Tower Impacts
  • Acid Rain Evaluations
  • Fuel Conversions
  • Severe Weather Analysis
  • Odor Characterization
  • Noise Evaluation
RECENT PROJECTS

Air Quality and Industrial Compliance
Gerdau Ameristeel
Sayreville, New Jersey

The facility is comprised of an electric arc furnace (EAF) that currently produces 85 tons of steel billets per batch heat process, and a rolling mill that forms the reinforcing bars from billets. Terranext has assisted this client with a range of environmental services, as highlighted below:
  • PSD Permitting
    Terranext is currently preparing a new PSD permit application to allow expanded production at this facility. The facility previously required assistance to proceed with a $40 million modernization project. Terranext was responsible for all aspects of the PSD permit application for the modernization, including BACT/SOTA and air quality impact modeling.
  • CEMS Protocol
    Terranext also prepared the CEMS protocol, wrote the CEMS specifications, reviewed CEMS proposals, selected the CEM vendor and assembled emissions information.
  • Title V Permitting
    Terranext prepared a Title V Operating Permit application for Gerdau Ameristeel's Sayreville mini-mill. The work included the development of an emissions inventory and determination of the emission rates each major emitting unit. State and Federal regulations that apply to facility operation are being reviewed and a compliance plan and Title V permit application are being developed.
  • SPCC Plan
    Terranext completed a Spill Prevention Control and Countermeasures Plan (SPCC). Work included identifying regulatory requirements, facility inspection for ASTs, preparing a tank location map, identifying SPCC team, determining role of team members, identifying reporting procedures, detailing response procedures and preparing the report.
  • Mercury, Dioxin/HAPs BACT/SOTA
    Terranext performed these additional BACT/SOTA analyses for the Melt Shop including cost effectiveness analysis of alternative approaches and associated balance of plant impacts, based on special request of State agency as a part of PSD permitting activities.
  • Mill Optimization Plans
    Terranext developed details and schedules for the Melt Shop process optimization program to reduce emissions and avoid triggering LAER requirements with a planned 50% mill production increase.

Project value is approximately $400,000 annually.



Air Quality and Industrial Compliance
Mount Sinai Hospital

Medical Center
New York, New York

Terranext is assisting this major metropolitan hospital in updating its air permits and emissions information to comply with the latest New York State and Federal Clean Air Act regulations under Title V. The facility operates six dual fuel-fired boilers to provide the hospital with 125 psig steam. Four of the boilers are rated at 60,000 lbs./hr steam production and two at 80,000 lbs./hr. Due to the size of the boilers, New York State regulations are requiring stack testing to comply with NOx RACT rules. Terranext designed and supervised the stack testing program and evaluated options (low NOx burners) for NOx control, as well as prepared emissions information and recommendations for record keeping systems sufficient to address the New York State permitting requirements. Terranext also prepared the Title V permit application and was responsibile for:

  • NOx RACT Compliance Plan
  • Boiler trouble-shooting
  • Emission Source Identification
  • Emissions Inventory/Quantification
  • Regulatory Review
  • Record Keeping/Reporting
  • Compliance Plan Development
  • Title V Application

Project value was $50,000.
