Particulates like sand are not disturbed and settle to the bottom, so visibility is good.
Best of all, the emissions will be well below the Clean Air Act's requirements with 99% of the sulphur being removed, and emissions of nitrogen oxides, carbon monoxide and particulates (tiny pieces of soot) being far lower than is possible using scrubbers.So far, two IGCC plants have entered service in America, with support from the Department of Energy.
They are a horribly inefficient mode of transport why move a ton of metal around in order to transport a few bags of groceries?—and they cause pollution, in the form of particulates and nasty gases.

Heavy goods vehicles make up less than 2% of all vehicles but they are responsible for a third of all nitrous-oxide emissions, nearly half of all particulates and a quarter of carbon dioxide generated by road transport.
New European Union rules in the Large Combustion Plant Directive impose tough limits on emissions of nasty oxides of sulphur and nitrogen, which cause acid rain, as well as of carcinogenic particulates.
On October 5th Boris Johnson, the city's mayor, set out his ideas on how to clean up.Two pollutants cause most of the problem: oxides of nitrogen, which damage the lungs, and fine particulates, which are also carcinogenic.

One theory is that a growing mass of particulates, such as coal dust and biomass (from the widespread use of cow dung as fuel, for instance) in the air above India, now hinders rainfall.
These, based on the presence of fine particulates, mostly ranged from "moderate" to "unhealthy" in the 24 hours after midday on July 31st.
