Air Quality

air quality

Liberty Environmental’s air quality management practice includes engineers and scientists who provide air quality permitting, emission inventories, air dispersion modeling, ambient monitoring, air emission testing and compliance services for industrial and government clients. We have experience preparing state construction permits and federal Title V, PSD and NSR air permits in more than 30 states. Our air quality services include preparation of greenhouse gas emission inventories and development of greenhouse gas management programs. We are experienced in designing, specifying, installing, commissioning and operating/maintaining air pollution control devices and ventilation systems.

Air Quality Modeling and Ambient Monitoring

Air quality dispersion modeling and ambient air monitoring are required for complex air permitting projects and are important components of regulatory agency air quality planning. Liberty Environmental’s air dispersion modeling expertise includes PSD NAAQS and PSD increment modeling, state air toxic modeling, and air quality planning services for government agencies. Our modeling expertise includes the ISC, AERMOD, and CALPUFF EPA regulatory models and the HYSPLIT trajectory model. Our GIS and mapping capabilities provide graphics that clearly communicate air modeling impact results and assist in communicating mitigation options. Liberty Environmental also provides air toxic impacts assessment and risk assessment services.

Ambient air monitoring services include installing and operating meteorological stations, siting and operating ambient air samplers, and air monitoring data management. We design, specify, install and operate PSD meteorological and ambient air monitoring programs. Other services include:

  • AERMOD Dispersion Modeling for PSD Projects
  • CALPUFF Modeling for Visibility Impacts at Class I Areas
  • Air Toxic Modeling and Risk Assessments
  • Nonattainment Planning for Government Agencies
  • Source Apportionment and Wind Roses (PMF, HYSPLIT)
  • Meteorological Tower Installation and Operation
  • Ambient Air Monitoring Stations – PM2.5 and Air Toxic Monitoring
  • Upper Air SODAR and RASS Monitoring – Wind Energy Assessments
  • Ambient Air Data Management and Website Development

Air Quality Permitting

Liberty Environmental routinely prepares air permit applications for customers at manufacturing plants nationwide. We have permitting and technical contacts with over 30 state air regulatory agencies, EPA Region offices, and EPA headquarters offices. We routinely prepare PSD and NSR major source permit applications that include air dispersion modeling studies, BACT analyses, air emission inventories, and regulatory assessments. We have also prepared numerous state construction permit applications, Title V renewal applications and minor modification submittals. Additional air permitting services include:

  • State Air Construction Permits, Permit-to-Install, and Plan Approvals
  • Title V Operating Permits
  • State Only and Synthetic Minor Operating Permits
  • Major Source PSD and Nonattainment NSR Permits
  • Air Dispersion Modeling – AERMOD, CALPUFF
  • BACT Analyses, LAER and BAT Determinations
  • Flexible Air Permitting – PAL Permits
  • RACT Assessments
  • MACT Compliance for HAP Emissions Sources
  • Air Pollution Control System Cost Estimation
  • CAM Plan Development
  • Permit Negotiations

Air Pollution Control Engineering

Liberty Environmental has broad expertise in the technical and economic evaluation of air pollution controls. Our engineering staff has decades of experience in manufacturing industries prior to their consulting careers. As such, we have contacts with many pollution control vendors and can sort through performance claims, compare pollution control systems and assess their relative capital and operating costs. We also offer the following air pollution control engineering services:

    • Air Pollution Control Device Specification, Design and Cost Estimation
    • Air Pollution Control System Troubleshooting
    • Air Pollution Ventilation System Evaluation and Design
    • Air Emissions Test Program Management
    • Air Emission Factor Development
    • Risk Management Plan (RMP) and Process Safety Management (PSM) Consulting and Engineering Services
    • Continuous Emission Monitoring (CEMS) Systems Design and Deployment

East Lycoming Wood Biomass Boiler Environmental Testing Hughesville, PA

This video courtesy of McClure Company Mechanical Contractors & Engineers, details the final phase of the East Lycoming School District’s biomass heating system commissioning. In the interview, Liberty Environmental Air Quality Expert, Gavin Biebuyck, is on site to explain the purpose of the air pollution emissions testing. Though considered a sustainable, carbon-neutral heating strategy, burning biomass material does produce air emissions that fall under the scrutiny of the U.S. EPA and Pennsylvania’s Department of Environmental Protection (DEP).

Expert Witness Testimony for Warehouse Zoning Approval Lehigh Valley, PA

With a commitment to serving as a trusted environmental advisor to our clients, Liberty Environmental takes a true business perspective to addressing municipal zoning and air pollution dispute matters. In this case Biebuyck’s testimony and approach in the expert report, not only supported the approval of the conditional use permit, but also allowed developers to move forward with the project without air monitoring and other potential costly conditions that could have been imposed.
