The EPA has given the green light for indoor propanes to start spewing CO2, methane and nitrous oxide into the atmosphere.
This is the latest chapter in the EPA’s war on air pollution and the first time that the agency has approved such a move.
A year ago, when the CO2-spewing indoor air pollutant was a new development, the agency was considering allowing indoor gas heating systems to emit even more CO2 into the air.
But the CO 2 emissions had already begun to fall since then, and the agency decided that a CO2 emission limit of 300 parts per million (ppm) would be a reasonable limit for the time being.
The new rule, however, is likely to push indoor gas heater emitters even further into the stratosphere than they already are.
It will require that the indoor gas generators meet the CO-spitting limit and the CO emissions will need to be measured at an outdoor facility that has not yet been approved for CO2 emissions.
The new CO2 limit of 30 ppm is still too high for most indoor gas heaters.
So indoor gas producers will need permits to operate outdoors.
The EPA says it will also require indoor gas operators to keep their facilities in compliance with air quality standards and to test for the presence of particulate matter.
So far, indoor gas companies are doing all of these things, but the EPA has not given a specific deadline for when those requirements will be met.
In addition, the EPA said that indoor gas systems with a capacity of more than 2,500 gallons (12,500 liters) of gas will have to meet CO2 standards, including those that apply to indoor boilers and refrigerators.
The agency is expected to issue the final rule this spring.
It is expected that the rules will cover the indoor use of gas heat as well as outdoor use of propane.
The latest round of CO2 regulations was approved by the EPA in November.
The agency has already announced the final rules for other industries, such as the construction industry.
But many indoor air pollutants will continue to be emitted, even if indoor gas technology improves.
