United States Environmental Protection Agency Office of Water (WH-547) EPA832-F-93-010 September 1993 &EPA Source Reduction Workshops Case Studies en P3 i o 03 a. 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. '• r 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. Printed on Recycled Paper ------- WnrkshOD Nn. 2 . Higher 1992 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.
