What are the DEP Boiler Requirements for a Triennial?
DEP requirements for specific boilers are typically renewable every 3 years, which is why they’re generally categorized as triennials.
Local Law 38 of 2015 amended requirements for DEP Boiler Registrations (separate from annual inspections filed with the DEP), and created two categories of Registrations:
Boiler Registration I (350,000 BTU/hr to less than 2.8 million BTU/hr) and -
Boiler Registration II (2.8 million BTU/hr to 4.2 million BTU/hr). Boilers over 4.2 million BTU/hr require Work Permits/Certificates of Operation.

Any boilers requiring Certificates of Operation or Registration II (from 2.8 to 4.2 million BTU/hr) must perform annual tune-ups and combustion tests in addition to the 3-year triennial filing.
Dates, processes, and results must be kept by the owner for a minimum of five years and must be submitted within 5 business days if requested by the DEP.
Failure to have current registrations/work permits can result in DEP-ECB violations – review general Air Permitting Forms and Instructions for additional details.
