The NOx Budget Trading Program (NBP) was a cap and trade program that began in 2003 and was designed to reduce NOx emissions during the ozone season (May 1 through September 30). Beginning in 2009, the NBP was effectively replaced by the ozone season NOx program under the Clean Air Interstate Rule, which required further summertime NOx reductions from the power sector.
