Operational Permits

The staff of Shell Engineering & Associates, Inc., includes environmental professionals with both regulatory and industrial experience. We use this expertise to assist our clients in meeting the continuously developing requirements of both the Title V and the state operating permit programs. We can assist you with any phase of the permitting process, including:

  • Determination of facility classification through “potential-to-emit” calculations.
  • Comprehensive facility compliance inspection.
  • Strategies to increase operating flexibility.
  • Alternative operating scenarios.
  • Review of applicable regulations and compliance determinations.
  • Developing corrective compliance plans.
  • Record-keeping and tracking systems.
  • Monitoring plans.
  • Preparation of complete and accurate applications.
  • Review of finalized operating permit.
  • Audits for compliance with finalized operating permit.

Our in-depth knowledge of federal, state, and local air regulations and compliance issues allows us to develop a complete permitting package that best suits your company’s existing and future needs.

Construction Permits

Shell Engineering and Associates, Inc., provides environmental air quality studies that can be grouped into the following areas:

Air Emission Analysis
The services offered by Shell Engineering are widely varied, but typically focus on air compliance issues. Services include quantification, assistance in emission inventory questionnaires, emission factor development, emission reduction analysis, emission management programs including compliance with MACT standards, indoor air sampling and oversight of stack testing activities.

Air toxic analysis includes monitoring, quantification of emissions, SARA reporting, modeling of air toxics and accidental releases, and the evaluation of control devices for technical and economic feasibility and evaluation of controls in reference to regulatory requirements. Odor and noise studies include assessment, examination of regulatory rules and environmental constraints, assessment of control technologies and development strategies to minimize the potential problems.

BACT Study and Its Integration for Pollution Control
Shell Engineering can provide detailed studies to determine the Best Available Control Technology (BACT) for controlling air pollutants at the client’s facility. A typical BACT study includes a technical literature search of control equipment that has been used on similar facilities/processes. Controls are rated on the basis of technical feasibility, economic feasibility and environmental superiority.

BACT is usually performed for facilities which are attempting to minimize air pollution. However, the same process can be used to analyze different process controls which may be applicable to the client’s facility.

Air Permitting & PSD Evaluation
Shell Engineering has extensive experience in all types of air permitting, including Prevention of Significant Determination (PSD) permits and has worked for a large variety of industries, including manufacturing, mining, and power generation.

Shell Engineering has a thorough and systematic approach to PSD evaluation. First, the experienced staff will determine if your environmental situation is applicable to PSD. If it is subject to PSD review, the modeling and engineering staff will:

  • Meet with state and federal agencies to discuss the approach that will be taken.
  • Provide a complete emissions inventory of the source in question and all sources within 50 kilometers.
  • Predict the impact of new construction or modifications (such as new boiler, expanded hours, more plant capacity or change in fuel type) using dispersion modeling.
  • Determine baseline air quality by modeling the source before change or construction begins.
  • If needed, locate the meteorological and ambient air monitoring sites through dispersion modeling.
  • Develop and implement an air monitoring program, install and operate monitors and provide quality assurance and monitoring data.
  • Perform BACT analysis using the most current EPA policies and clearinghouse information.
  • Complete and submit the PSD application to the appropriate agency.
