I'm almost at a loss for words.
After all the posturing and lecturing about how California is the "toughest in the nation" I read that THIS document for Contra Costa county
http://basmaa.org.dnnmax.com/Portals/0/documents/pdf/Pollution from Surface Cleaning.pdf says just plain as day that wash water from plaza cleaning can go straight down the storm drain after initial dry cleanup just like ours here in Las Vegas does.
I don't understand this Jim Gamble. The search function says you are a "certified" company and have gone through their training, but yet you still try to scare the daylights out of people to convince them that everything must be vacuumed and filtered.
Obviously this must be a new "loosening" of their rules. Surely it can't be old rules or you would have let us know that plaza cleaning water can, in fact, go down the storm drain in Contra Costa County.
