The federal government seems to have determined if the air pollution plaguing the Imperial Valley comes from across the border, it doesn't really count as much.
Recently federal experts decided that much of the Imperial Valley's dust problem, in air pollution terms known as PM-10, emanates from Mexicali. So the feds recently decided the strictures on the Valley regarding dust-based pollution won't be as stringent as they could be.
That likely will be good for Imperial County, at least as far as the economy goes. As far as our lungs go, well, that might be a different story. But at least those of us who have been in the Valley are accustomed to the dust.
Something new that will be plaguing our Valley are emissions from two huge new power plants set to go online right across the border from Imperial County in the Mexicali area. The natural-gas fueled plants will fill the air of Mexicali with pollution, and since we are in the same air basin as Mexicali, our air also will be plagued. The main pollutant will be nitrogen oxide, which can cause respiratory problems and play a factor in bringing acid rain and damaging water quality. Such emissions are dangerous to human health, both long-term and short-term. This in an area already marred by high allergy and asthma rates.
