• Stack Testing:
    Some air permits require emissions testing to verify that control equipment is capturing pollutants and operating efficiently. Chem-Tech contracts with leading reputable testing companies to fulfill our clients’ stack testing needs.

  • Indoor Air Quality Sampling & Assessments:
    As part of a hazard analysis involving airborne contaminates, the breathing air must be tested to ascertain the concentrations of contaminates in the air. Chem-Tech provides full services to ensure that OSHA indoor air quality standards are met. Where areas exist that exceed air quality standards, Chem-Tech has the knowledge and experience to help engineer solutions.


  • Air Permits (Title V, Synthetic Minor, State Permits, etc.):
    Air Permits are needed prior to the installation and operation of an air emission source. Some sources require reports of emissions on a periodic basis. Chem-Tech can perform the necessary calculations and consultation that are needed to properly file the permit and prepare reports.

  • Air Permit Exemption Documentation:
    Not all air emission sources require permits. However, to claim an exemption, documentation must be on record to prove that the source emits less that the threshold of contaminants. Chem-Tech can assist with the evaluation and calculation to document air emission exemptions.

  • Permit Recordkeeping & Reporting Assistance:
    Accurate and current recordkeeping is a requirement of air permits. Chem-Tech will assist in the up-to-date record keeping, calculating, and reporting of air emission sources.

Risk Management

  • Risk Management Planning (Section 112(r) of the Clean Air Act Amendments of 1990):
    Section 112 (r) of the Clean Air Act Amendments of 1990 requires a risk management plan to be prepared, submitted, and implemented if certain toxic or flammable chemicals are stored on site in threshold quantities. However, if any amount of these chemicals are stored on site, they must be evaluated and the facility designed to prevent the release of the chemicals. Also, a release occurs, procedures must be in place to minimize the consequences of the release. Chem-Tech can assist with a full plan or integrating procedures into the company Emergency Action Plan


SARA Title III: The Superfund Amendments and Reauthorization Act (TITLE III) was formed in response to the Bhopal Disaster. The Act requires industrial plants to work with local and state governments to prepare an emergency response plan. In addition, the Act imposes numerous annual reporting to assure that state and local officials are aware of the hazardous substances used or stored at the facility. The Act also requires immediate reporting of accidental releases to the environment.

  • SARA 312 – Inventory Reports:
    Section 312 requires the facility to report each year by March 1 the inventories of chemicals over a certain threshold if that chemical was stored at the site some time during the year. Chem-Tech can help in the understanding of the requirements and assist in compliance.

  • SARA 313 – Toxic Release Inventory:
    Each year by July 1, the amount of certain chemicals released to the environment must be reported. Chem-Tech will list the chemicals and their threshold for the previous year as well as submitting the appropriate forms for each chemical.

Air Quality


  • Emissions Inventory Assessment:
    An emission inventory is an itemized list of air pollutant emissions from both permitted and unpermitted sources at a facility. The assessment is designed to determine not only a facility’s actual emissions, but also the facility’s Potential to Emit (PTE). The permit and regulatory requirements for your facility are largely determined by the facility’s PTE. Chem-Tech will calculate emissions using various methods and procedures including engineering calculations, EPA or trade group emissions factors, or direct measurements. Present and future year emissions inventories are critical components of compliance with air quality regulations.

  • BAT Control Equipment Cost Effectiveness Studies:
    When potential emissions for a new project exceed certain thresholds, EPA requires that a best available control technology study be done to determine if add on pollution controls will be required. Chem-Tech can complete this study, comparing different control options that EPA would then use to make a final determination. In many cases, the determination will be that additional control equipment is not mandated.

  • Pollution Prevention & Cost Savings:
    Pollution prevention does not always mean higher costs. Chem-Tech can assist in identifying areas to save money such as materials reduction or replacement, material reuse or recycling, and energy conservation.


  • Air Dispersion Modeling:
    Occasionally, EPA requires air dispersion modeling to determine the maximum ground level concentration of certain air pollutants past the facility’s property line. Modeling is typically required to determine if air pollution control equipment will be required for a new project prior to issuing an air permit. Chem-Tech primarily uses the SCREEN3 program for air dispersion modeling.
