1988 NSPS for Residential Wood Heaters
On February 26, 1988, EPA issued New Source Performance Standards (NSPS) that govern the manufacture and sale of new wood stoves, and certain wood burning fireplace inserts built after 1988.
The 1988 standards were amended on November 24, 1998, to prohibit the sale of wood heaters that had their original certification revoked due to an invalid certification test. This action did not affect wood heaters that had already been sold to consumers.
