they do not use their washing machines to wash industrial, hospital/clinic, or commercial uniforms, wipers, mats, or mops; industrial, hospital/clinic, or commercial linens; diapers; or carpets, but may not discharge cleaning solvents (e.g., perchloroethylene), including solvents in their cooling water discharge.

- (f) A onetime only Discharge that receives prior written approval of the Authority.

A request to Discharge uncontaminated water will be denied unless the discharger has no reasonable alternative. Written approval may be granted by letter, with the approval of the Municipality, if there are no necessary conditions on the Discharge other than the location, volume, time and duration of the Discharge, and the general requirement to meet Authority limits. A permit is necessary, or an existing permit must be modified, if there are conditions appropriate for the Discharge in addition to location, volume, time, duration and meeting Authority limits, such as sampling, reporting or pretreatment.
