Specifications

It is crucial that you contact EH&S before purchasing your portable generator / equipment to ensure that it meets current emission requirements. If a generator / equipment is purchased that does not meet emissions criteria, it cannot be permitted and installed.

If your portable generator set is

  • larger than 50 horsepower (hp), you are required to register the engine to comply with air quality regulations.
  • less than or equal to 50 horsepower (hp), you are not required to register the engine.

The permit process can take up to 4 months to complete. A general timeline of the process is as follows:

Recordkeeping

The owning department should keep a log that indicates:

  • Date
  • Hours of operation for reliability-related activities (maintenance and testing)
  • Hours of operation for emission testing
  • Hours of operation for emergency
  • For each emergency, the nature of the emergency condition
  • Receipts of fuel purchased
