[Code of Federal Regulations] [Title 32, Volume 4] [Revised as of July 1, 2002] From the U.S. Government Printing Office via GPO Access [CITE: 32CFR650.65] [Page 313] TITLE 32--NATIONAL DEFENSE CHAPTER V--DEPARTMENT OF THE ARMY (CONTINUED) PART 650--ENVIRONMENTAL PROTECTION AND ENHANCEMENT (AR 200-1)--Table of Contents Subpart C--Water Resources Management Sec. 650.65 Minor industrial and municipal operations. Wastewater discharge from minor industrial and municipal facilities such as wash racks, engine steam cleaning operations, water treatment plant backwash, swimming pool filter backwash, and other similar activities will be connected to the sanitary sewer wherever feasible. It should be noted that effluent from these activities not connected to sanitary sewers requires an NPDES discharge permit. To eliminate costly and difficult treatment and monitoring programs all possible efforts should be directed to connecting with the sanitary lines. At remote locations, a holding tank may be used which is sized to hold all drainage between pumpouts. After pumpout, the wastewater will be transported to another location for treatment and disposal. Other alternatives include onsite treatment which would require a discharge permit, or a closed cycle system which would treat and re-use the wastewater. In the latter case, if there were no discharges, a permit would not be required.
