I would Appreciate if you left my name out of this thread....no one one here knows my business or my finances.....Nor do i I i want people calling me and asking...because it is my business not anyone else's.
In looking for effectiveness of structural BMPs I found thisnresource - thorough breakdown of types and effectiveness, a must read for all contractors to further understanding of this topic.

I'll take a crack at this Steve-- In your above example I'd say yes. Obviously don't ever hold me to that because I'm not legal council."If your discharge wash water does not reach water of the United States, there are no requirements under the CWA. No off property discharge."
Does this not pretty much end the conversation for the majority of sidewalk and building cleaning contractors using water only on regular maintenance accounts?
On your last question here above-- the problem seems to be what is considered to be reasonable methods of removal of debris and removing oil in the Persons Geographical area of employment..So if these elements are incorporated onsite and the pressure washing contractor is applying reasonable methods in removal of debris and removing oil - where is the problem?
This line here says a ton--"Building codes and local government ordinances vary greatly on the handling of storm drain runoff"But if the wash water is going to an on property structural BMP approved by code enforcement prior to construction and passed on inspection, are we not meeting our obligation? If designed correctly and matched to property type/runoff produced it will not ever reach MS4 or US waters.
I believe that for the specific area of sidewalk cleaning/drive thru cleaning we are dealing with runoff issues further down the chain of CWA/EPA compliance - the 'big fish' have already dealt with compliance at a local and state level when having construction plans approved (educated guess, I can not cite a specific reference at this time). If a violation slips through the net at pre-construction plan approval, code enforcement inspection, etc. and we have performed 'good housekeeping' (sweeping, debris removal, mud collection, oil sheen removal) who is responsible?
More to be gained further up the chain from us...
I am not advocating off-property discharge or irresponsible practices, but we seem to be missing the point on this issue is often taken care of at the construction stage.

Can anyone cite studies (other than what is here: http://cfpub.epa.gov/npdes/stormwat...action=factsheet_results&view=specific&bmp=72) on effectiveness of bio retention areas?
Or information on on-site stormwater management building/development code standards for commercial new construction. I want to look at this from another point of view in that where the responsibility for waste water lies with property owner... Has treatment for discharge already been taken care of in the form of dry retention/detention ponds, interceptors, bio retention ponds (lined/unlined), grassed swales, etc.
