But most of the land was swamp when we started, full of decaying matter, which emits
tons of methane gas," Marie said, as she massaged her temples with her one free hand in an obvious effort to stave off a tension headache.
If these plants have not made changes that increase the amount of air pollution they emit
, or are not emitting any new pollutants, they do not have to satisfy the requirements.
In addition to the above requirements for emissions units with a potential to emit
after control that is greater than or equal to major source status, CAM plans must be submitted as a part of a significant permit revision under Part 70 or 71.
It has been calculated that 12 average-sized trees emit
about the same volume of hydrocarbons in one day as a new car driven 30 miles.
Under the law's new, lower emissions thresholds, even smaller companies may emit
enough pollutants to earn the "major source" title.
By varying the size of the dots, researchers can tune the crystals to emit
73 million commercial and residential lawn mowers, blowers and other utility tools emit
22 tons per day of volatile organic compounds - more than is put out by all the aircraft in the South Coast Air Basin, officials said.
If an "open molder," under the "worst possible" assumptions for spray-up, emits
16% of its resin usage as styrene, it would hit the max.
However, the biodiesel plants that produce biodiesel do emit
GWG because they require heating input usually from natural gas, which is not renewable and emits
CO(2), and they also require electricity from local utilities, which emit
CO(2), and finally the chemical processes uses 10% methanol (wood alcohol) usually supplied from sources outside the U.
Lin says his group plans to develop tungsten photonic crystals that include, on a single microchip, both a heated region that emits
infrared radiation and another region that converts those thermal emissions into laserlike beams for driving telecommunications networks.
Weaver will also report on a new blue PHOLED material system that emits
light with a 30% narrower line width of 50 nanometers (nm), as compared to typical values of 75 nm or more.
In a laser, material between two mirrors spontaneously emits
photons, some of which bounce back and stimulate the coordinated emission of vast numbers of photons.
