About the article "Choosing compost or clean air: Rule to lessen smog would hurt efforts to reduce trash at landfill," (May 10, Page A-1): I guess this means that Grover Environmental (part of Grover Landscape) will have to start using these new air filters, too. Grover has 67 acres out in Vernalis that they use to turn green waste into compost. I'm sure that they produce a lot more smog-producing agents than the city of Modesto does on its 30 acres.
I used to drive a big truck for them. My truck and three others and a couple subhaulers would go to Berkeley every morning and bring back 20 to 25 tons of green waste, five days a week. You do the math. They have trucks coming in there from all over the Bay Area all day, long-hauling in green waste.
