This topic came up on another internet site and here's a link that pertains to it. I guess this issue affected one area of California at that time...don't know if it's still in effect or if it has been passed in other areas. Other posters on the other site pointed out that it affected only those who have their systems draining into the sewer system and that the salt concentrations targeted in the law are usually not those of residential pools (which are lower).

I'm not an expert about this, but this article should give anyone who's interested a starting point.
