Car Wash Wastewater

In behalf of a local sanitary sewer agency I am doing a review of
products used by car washes (both self-serve and automated).  

The idea is to evaluate chemicals that are discharged into the sanitary
sewer, such as shampoos, spot removers, wheel cleaners, carpet cleaners,
and so forth.

Two questions:

        (1) Have any of you undertaken a similar study?

        (2) Has the EPA issued a "development document for 
            effluent guidelines..." for this kind of wastewater?

Thanks for your input.
