The short answer is probably that the Federal Government is not requiring the State of Washington to measure it so why spend to do it if they don't have to? The Federal Government has different requirements for every State depending on the local air quality, population density, industry, etc. As an example, not all States have had to put vapor recovery on gasoline dispensing nozzels, at least not yet. The States have to show compliance with the Federal Government to continue to get Federal money so they will do only what they HAVE to do to keep the money coming. California is one of the exceptions, they try to do MORE than the Federal government requires. In any case if the other #'s are good then the NOx will usually be OK. There is not a whole lot you can do to affect NOx. David Teitelbaum vin 10757 --- In dmcnews@xxxxxxxxxxxxxxx, "Dave" <v-davidj@xxxx> wrote: > Hey Marc... > > Good question....I don't know.
