Suspected unlawful hazardous waste generator. This is a major commercial spray painting operation in a completely residential neighborhood, and just a stone's throw from an elementary school. The scofflaws weld metal and use big spray guns powered by air compressors in the open air and without vacuum hoods and particulate filters as I believe would be required. For example, see this application: http://ddoe.dc.gov/sites/default/files/dc/sites/ddoe/publication/attachments/Paintbooth_Application_Update_2010-08.pdf
I have video and photographic evidence of these environmental crimes and will testify against any properly indicted defendants in an open court of law if needed.
