 Best Management Practices



 For  Protecting  Ground Water


     For Print Shops  Using Shallow


     Industrial Waste  Disposal Wells

     (Class V Well BMP Fact Sheet Number 2F)


EPA recognizes that certain industrial waste disposal practices using drainage wells may pose unacceptable risks
to Underground Sources of Drinking Water. These operations allow the discharge of various wastes to a drainage
system neither designed for nor capable of treating them. Accordingly. BMPs for Industrial Disposal Wells focus on
well closure and alternative disposal methods. We have also included BMPs for waste minrmization to help
facilities reduce waste disposal costs, regardless of the disposal method they use In addition local county and
State regulations may prohibit use of these wells. Note: these practices are recommendations only' For more
information, contact the person named below


      The BMPs listed below apply to print shops. Fact Sheet Number 2 in this series
      lists BMPs that are applicable to Industrial Disposal Wells in general (including
      those used by print shops), particularly for closure and alternative disposal.


      Waste Minimization


       •  Use photomechanical, electrostatic, and surface plate processes rather than
         metal etching and plating since the former generate smaller amounts of hazard-
         ous waste

       •  Use electronic imaging for editing and print only final versions on paper to
         reduce chemical (and paper) use

       •  Use water-based or soy-based inks, where possible, to minimize petroleum
         concentrations in waste water

       •  Install automatic web splicers and web break detectors

       •  Install automatic blanket cleaners

       •  Use automatic ink levelers

       • Standardize ink sequence and ink rotation to the greatest extent  practicable

       • Use aerosol spray in place of solvents to clean out ink fountains at the end of
        print runs to prevent drying and clogging

       • Use countercurrent washing where appropriate
                    Note. These BMPs are adapted from a May 1991 EPA report titled, 'Class V Well BMP Guidance - Phase I and
                    Phase II," and have been modified in response to comments by EPA Regions. For a copy of the EPA report,
