Air Quality & Clean Air Act Compliance

Air EmissionsESS assists industrial clients with air permitting, air quality and emissions assessments, control technology assessments, and interpretation of complex air quality regulations using a wealth of project engineering and regulatory experience. We work with clients to develop permitting and compliance strategies that minimize regulatory burdens, maximize operating flexibility, and facilitate business goals. ESS develops the best permitting strategy to achieve these goals, while streamlining the permitting process to facilitate timely review and approval.

Air Quality Permitting

ESS air quality consultants and engineers have more than 80 years of combined experience in air quality permitting for facilities ranging from 1100 MW power plants to supplemental diesel generators. They are familiar with the emissions characteristics and control technologies associated with many manufacturing processes including those for textiles, paint, baked goods, soaps, asphalt, and film. ESS also maintains excellent working relationships with senior air regulators in state agencies and Environmental Protection Agency. We have recognized air quality experts on staff who are routinely invited by agencies to participate in regulatory workgroups. ESS works with our clients to prepare applications for:

  • New Source Review (NSR) and PSD Permits
  • Minor Source Air Permits and Permit Modifications
  • Title V Operating Permits
  • Facility Modification and Expansion Strategies
