PROGRAM DESCRIPTION                j
     The Metropolitan Waste Control Commission (MWCQ
in St Paul, Minnesota is presenting three pollution prevention
(PP) workshops designed to educate the municipal wastewater
community (e.g., POTW staff and industrial dischargers) in PP.
This project is funded with a $100,000 matching grant from
EPA's Pollution Prevention Division.  The Minnesota Technical
Assistance Program (MnTAP) supportsJUWCC by organizing
the three workshops and providing technical assistance.
Primarily funded by the Minnesota Office of Waste
Management, MnTAP is a nonregulatory unit that provides PP
assistance to businesses and organizations in Minnesota.
MWCC is the largest POTW in Minnesota and includes 11
plants serving 105 communities and approximately 750
industrial dischargers.                     '

PROGRAM OBJECTIVE
     MWCC has two main objectives for the workshops: (1)
to better educate their staff so that they are able to teach
industrial users about alternative waste management practices,
including PP and (2) to achieve reductions in the concentrations
of pollutants and volumes of wastewater discharged to
MWCC's wastewater^treatment system through PP at the point
of generation.      ;"

     Three workshops were scheduled, one in April 1992,
another in October 1992, &hd;the final one in March 1993.
Their goals were to identif^lirect applications for PP
techniques such as source reduction and municipal water use
efficiency. These workshops were designed to motivate the
municipal water community  supplier, manager, or user of
water resources- to utilize PP techniques. The following
workshop descriptions highlight the topics covered.

Workshop No. 1 - April 1992              '
    The first workshop involved approximately 50
participants consisting of MWCC pretreatment program staff,
MWCC staff committee members, representatives from seven
other Minnesota POTWs that have federally approved
pretreatment programs, Minnesota Pollution Conteol Agency
industrial wastewater staff, and representatives from county
hazardous waste programs. This first workshop lasted a half
day and aimed to shift participants' orientation from
pretreatment towards PP. PP activities at the state and federal
level were discussed to provide participants with a basis for
understanding local PP initiatives. A worksheet on PP
opportunities for POTWs was used during small group
discussions. MWCC intends to use the worksheet to identify
areas where further education could help POTW personnel
promote PP. The worksheet addressed the following topics:

1.  What can POTWs do to prevent pollution and contribute to
   Minnesota's effort to prevent pollution at its source?

2.  How can POTWs balance their roles as "regulator" and
   "technical assistance provider"?

3.  What tools, training, staff development, and resources will
   a POTW need to implement an effective PP program?

4.  What PP opportunities exist.outside the industrial
   discharger arena (e.g., PP opportunities with commercial
   businesses and the general public)?

5.  How can POTWs identify and communicate PP
   opportunities to dischargers?           	

6.  How much must a POTW inspector know about
   dischargers' processes to provide PP assistance?

7.  How can POTW inspectors integrate PP into their jobs?

8.  To whom does a POTW inspector refer dischargers for
   further informatiom?

9.  How can POTW inspectors coordinate PP opportunities
   with other agencies;?

   Addressing these issues will facilitate the development of
   an approach to PP based on cooperation rather than
   regulatory penalties.

        The second workshop involved 80 participants
   representing the same organizations as in Workshop No. 1.
   Using the worksheets completed during Workshop No. 1,
   MnTAP designed the second workshop to provide detailed,
   technical information on PP techniques, primarily geared
   toward wastewater. The purpose of this workshop was to
   integrate PP into pretreamient inspections and other POTW
   programs, identify PP opportunities, identify opportunities for
   MnTAP to provide technical assistance, discuss PP success
   stories, and review industrial PP plans and annual progress
   reports.

       After the keynote address and a general introduction on
       PP,  there were 13 different breakout sessions, each lasting
       45 minutes, on various topics for the participants to choose
       from:

       Q   Food Industries I: Keeping Food Materials Out of
           Wastewater

       Q   Food Industries IT: Recycling Restaurant Food as
           Livestock Feed

       Q   Photoprocessing

       Q   Printing

       a   Machining/Cutting Fluids and Coolants

       a   Parts Cleaning

       Q   Electroplating and Metal Finishing

       Q   Printed Circuit Board Manufacturing

       Q   Commercial Sources

       a   Household Hazardous Waste   .

       Q   Nonpoint Source Pollution

       Q  Greater Minnesota's POTW Issues

       Q  Lake Superior Partnership

        Following the breakout sessions, there was a general
   session  entitled "SARA Title m Section 313 - Pollution
   Prevention Plans and Progress Reports." Finally, the group
   discussed "next steps" and adjourned The workshop was well-
   received and the participants commented that they found it
   extremely informative.
Workshop No. .1 . March 1993
     The final workshop included participants from Workshop
Nos. 1 and 2 as well as staff from other POTWs and industrial
users of the sewage treatment system. This workshop included
roundtable discussions on PP designed to allow the industrial
users and POTW staff to share ideas and PP experiences.
Again, results of the worksheets from the previous workshops
were used to guide presentations and discussions in this
workshop.

PROGRAM ACCOMPLISHMENTS
     It may be several years after these workshops have been
completed before the accomplishments become fully apparent
However, MWCC anticipates that the workshops will make
both the regulatory agencies and the regulated community more
aware of opportunities to implement successful PP programs
focusing on source reduction. The process of developing,
planning, and conducting these workshops, however, has
already served to increase awareness and appreciation for PP
techniques on the part of personnel at MWCC, other POTWs,
and industrial facilities using these wastewater treatment
faculties.
