Regulations issued by the New York City Department of Environmental Protection will phase out the use of No. 6 and 4 heavy heating oils in New York City.  The regulations were designed to balance near-term pollution reduction while minimizing costs for buildings.

• All new boiler or burner installations must utilize one of the cleanest fuels, which may include natural gas, ultra-low sulfur 2 oil, biodiesel, or steam.
• Beginning July 1, 2012, No. 6 oil Certificate of Operations will not be issued.  At a minimum, buildings will be required to convert to a fuel as clean as No. 4 oil. 
• All buildings must convert to one of the cleanest fuels upon boiler or burner retirement or by January 1, 2030, whichever is sooner.
• Compliance waivers will be considered through the New York City Department of Environmental Protection.
