If you want to know where some of the worst places in America are for ozone and particulate pollution, look no farther than California.

Agency labels diesel engine exhaust emissions as ‘carcinogenic’ and other revelations

In a May 1st Air Quality Matters blog post, I referenced the Unites States Environmental Protection Agency’s (EPA) document titled: “Second Report to Congress: Highlights of the Diesel Emissions Reduction Program,” a document to be of particular relevance and importance. (To learn more and read what I had written, see: “EPA’s Diesel Emissions Reduction program is showing promise”). … Read more

At one part in particular in the previous post, in essence, I asked if it is not more economical to expand California State Route (SR) 99 – which is currently being widened from four to six lanes at various spots between Kern County, located in the south San Joaquin Valley, and Sacramento to the north, rather than to … Read more
