Thank you for your responses. However, here in California, we can not use any dry cleaning product that is left on the surface being cleaned and reapplied over and over. It works great for making the stains disappear - We would like to be able to use these products in between our pressure washing services - but the metals found in used automotive fluids are not remediated with these products - they are invisible, but metals (such as copper, lead, zince mercury, cadmium) are just as toxic as the oil and grease. Here, The Department of Fish and Game as well as Storm Water Agencies review the Material Safety Data Sheets of our cleaning agents and they have told us to absolutely not to use any cleaning agent that is left on the surface, because when it rains they built up concentrations which will ultimately wash into the storm drain straight into our drinking water. Some of the MSDS of these dry cleaning products state vary clearly that their products "react violently to water".

Also, we can not recycle and reuse our wastewater, particularly when pressure washing to remove oil and grease, because once again the contaminant levels and the soaps build up at some point in our waste water. Our waste streams have been profiled over and over by many jurisdictions through out California and there has been only two cities stating that we don't have to pretreat prior to sewer discharge, because of the level of oil, grease and metals. We are required to pretreat our waste water on site of each cleaning activity and discharge clean water to the on site SEWER. We can not comingle wastestreams according to the Department of Toxic Substances. In other words we can not generate a waste stream at one location and reuse it or dispose of it at another clients location. We can not haul offsite without obtaining a hazardous waste haulers license and manifesting our waste. The government wants to know where the waste water as well as our solid waste is being disposed.

We are also required to obtain a sewer discharge permit from each jurisdiction through out California where we provide our service because the sewer discharge requirements and regulations vary from jurisdiction to jurisdiction. In other words, we can't use our permit issued by Los Angeles in San Francisco.

We have designed and patented a mobile system that utilizes clay based flocculents to pretreat our waste stream - which work very well in pulling and permanently fixating the metals, oil and grease from our waste stream in one easy step, within minutes. However, we are having difficulties in getting work - getting discouraged - and was just wondering how everyone else is dealing their waste streams through out the U.S. Is there anyone out there that is successful as an environmental surface cleaning company? We sure would like to hear from you.
