Next steps for Compliance Certification: Stationary Engine or Turbine

  1. What to Know

    You need to certify to MassDEP that you are complying with all applicable environmental requirements:

    • Within 60 days of installing an Emergency generator, fire pump or other similar engine rated at 37 kilowatts or more, or
    • At least 30 days before installing a Non-Emergency engine rated at 50 kilowatts or more.

    Workbooks, instructions, and forms are provided on this web page. Please note that there are differences in the requirements for Emergency and Non-Emergency engines and turbines, so be sure to select the documents that apply to your installation.

    Notes:

    • Most Emergency units qualify for the compliance certification option.
    • Many Non-Emergency units do not, but may still be installed. Please consult with MassDEP before proceeding. You may need to submit a comprehensive plan application (CPA) instead.
    • There is a streamlined CPA option for combined heat and power (CHP) facilities that generate both power and usable heat from a single engine.

    See Air Plan Approval Applications to learn more.

  2. Review the Applicable Workbook & Instructions

    Learn about your environmental obligations and how to complete your compliance certification.

    Be sure to select the workbook and instructions that apply to your installation (Emergency or Non-Emergency).

  3. Complete & Sign the Applicable Certification

    Be sure to select the form that applies to your installation (Emergency or Non-Emergency).

    You may fill out and save the Microsoft Word form on your computer. The PDF version has to be printed out and completed by hand.

  4. Obtain Supplier Certification, if Required

    For each new Non-Emergency engine or turbine you are installing, the equipment supplier(s) will need to certify that the unit meets specific limits for emissions of ammonia, carbon dioxide (CO2), carbon monoxide (CO), oxides of nitrogen (NOx), and particulate matter.

  5. Prepare a Return to Compliance Plan, if Necessary

    Complete and submit this form only for violations you were unable to correct before certifying, and be sure to select the form that applies to your installation (Emergency or Non-Emergency).

    You may fill out and save the Microsoft Word form on your computer. The PDF version has to be printed out and completed by hand.
