We have conducted over 3,000 air pollution and meteorological studies and monitoring programs. Table 1 provides the approximate number of organizations we have conducted these studies and monitoring programs for by industry grouping.

New Source Review Studies for Private Industry

We have conducted New Source Review (NSR) studies in support of construction permit applications for 27 companies throughout the eastern half of the U.S. Many of these studies have included all the required tasks to obtain Prevention of Significant Deterioration (PSD) construction permits.

Air Pollution Permitting for Private Industry

We are one of the most experienced firms in the United States conducting air permitting for existing and planned new facilities This work includes conducting all technical analyses, preparing permit applications and negotiating permits under the Title V operating permit program, Prevention of Significant Deterioration construction permit program and other operating and construction permit programs.

Our staff has prepared Title V operating permit applications for over 120 projects for 32 companies in ten states.

In addition, Enviroplan Consulting has written over 2,000 air permits under contract with state and local air pollution control agencies for projects in private industry. This work involved the development of comprehensive air emission inventories, assessment of regulatory compliance, evaluation of alternative facility operating scenarios, development of Compliance Assurance Monitoring protocol plans and preparing MACT and NESHAP permit requirements for a wide range of industries.

Model Attainment Demonstrations for PM2.5 and Ozone SIPs

We have conducted and continue to conduct emissions inventory development, control scenario evaluation and regional (CAMx and CMAQ) and local scale modeling to influence state agencies in their ozone, PM2.5 and visibility Model Attainment Demonstrations for State Implementation Plan revisions in several Nonattainment Areas on behalf of our industrial and electric power company clients.

Air Pollution Emission Inventory Development

The development of emissions inventory data bases has been a key element of the air quality services supplied to our clients. Our staff has developed facility emissions inventories in support of Title V operating permits and state Annual Emissions Statements. Many complex emissions inventories have been developed for fugitive emissions sources from coal-fired power plants and material handling facilities.

For nearly every air quality modeling study, our staff has conducted emissions inventory development. Our experience includes conducting engineering calculations, analyzing emission measurement data, and checking emissions inventory data with respect to published values. This experience also includes evaluations of control equipment efficiencies from both design and operating standpoints.

In our work writing over 2,000 air pollution construction and operating permits for state and local air pollution control agencies, we have developed many of the air pollution emissions inventories and in other cases reviewed and corrected the emissions inventories developed by permit applicants.

Air Quality Modeling

We have conducted over a thousand air quality modeling studies.

Our air quality dispersion modeling studies include those for existing facilities in support of State Implementation Plan (SIP) revision requests as well as for new facilities including Prevention of Significant Deterioration (PSD) permit analyses, nonattainment area impact analyses, and assessments to be included in Environmental Impact Statements. Our staff's experience in these areas includes the validation and application of alternative air quality dispersion models.

Our air quality modeling studies have included:

• Modeling in flat and complex terrain;
• Modeling of plume impact on tall buildings;
• Modeling aerodynamic downwash effects;
• Fugitive particulate emissions modeling;
• Cooling tower vapor and drift emissions modeling;
• Lakeshore and coastal fumigation modeling;
• Modeling of accidental releases of hazardous air pollutants;
• Long range transport modeling for concentrations, atmospheric visibility and atmospheric wet/dry deposition impact analyses in PSD Class I areas;
• Cumulative background source modeling;
• Modeling for monitoring network design; and
• Modeling in urban areas with large point and area source emissions data bases.
• Regional air quality modeling.

Our air quality modeling experience and capabilities include application of the models in Table 3 among others.

Hazard Assessments and Risk Management

Enviroplan Consulting has helped its clients in several industries comply with the chemical accident prevention requirements under 40CFR Part 68. Our services include:

• Determining whether and for which chemicals a facility is subject to the requirements of 40 CFR Part 68.
• Developing and implementing programs to exempt some or all of the chemicals from Part 68 requirements, and helping the client determine whether it is subject to the Program 1, 2, or 3 requirements.

Air Pollution Control Technology Evaluations

Our staff has conducted numerous studies involving the evaluation of the technological and economic feasibility of air pollution control equipment for a wide range of emission sources. These studies have included BACT/LAER determinations in support of New Source Review permitting activities, case-by-case RACT plans for existing sources in nonattainment areas, and engineering studies to specify and oversee the installation of air pollution control equipment. We prepared the above air pollution control technology evaluations for many of the over 2,000 air construction and operating permits we prepared for state and local air pollution control agencies.

Compliance Management

Enviroplan Consulting develops Compliance Management Systems based on the principles of ISO 14001 to help clients improve their management processes for complying with all environmental regulations.

Our work has included:

• Identifying the compliance tasks the facility is responsible for,
• Assuring there is clear responsibility for who completes each task,
• Documenting the steps in each compliance task via Action work Forms,
• Building ownership and commitment of the front line people responsible for actually carrying out each task,
• Developing a Management Checklist to assure follow up so that if a compliance task is not completed when required this is known immediately and the responsible person is contacted,
• Keeping track of any outstanding corrective actions needed to maintain compliance.

Our staff has helped companies improve their environmental compliance management processes and develop compliance management systems at over 20 facilities. The benefits of these services are not just more effective compliance but in many cases lower costs of compliance.

Community Right-to-Know Reporting

The Superfund Amendments and Reauthorization Act (SARA), Title III Sections 312 and 313 established reporting requirements concerning chemical inventories and chemical releases to the environment for more than four million businesses. Sections 303 and 304 have also established requirements for planning, detecting, reporting and assessing the impact on public health of emergency releases of designated chemicals. We have prepared many SARA Title III Sections 312 and 313 annual reports including the Toxic Release Inventory Forms for our private sector clients. Our experience has been over a wide range of industries including the automotive, chemical, coatings and resins, manufacturing, petroleum, pharmaceutical, pulp and paper, steel and coke industries.

Review of Air Permit Applications for State and Local Air Pollution Agencies

Since 1991, Enviroplan Consulting has been under contract to 11 state and local air pollution control agencies to support their air pollution control programs.

During this time we have prepared over 2,000 Title V, Title I, minor source, and other construction and operating air permits.
