3M Environmental, Health and Safety Operations Example: Printing Press  Minor source for Title V, New Source Review  Ozone nonattainment area  Emissions – Volatile Organic Compounds (VOC)  Potential emissions: less than 5 tons per year  Actual emissions: less than 1 ton per year  Control equipment required (“RACT”)  $25,000 – 45,000 per year6 © 3M 2010.

3M Environmental, Health and Safety Operations Example: Sponge Making  Major source for Title V, New Source Review  Ozone nonattainment area  Proposed 1 lb/hr VOC increase  Requirements driven by applicable emissions limit (RACT)  Permit change and SIP revision required for insignificant change; added 6 months to project7 © 3M 2010.

3M Environmental, Health and Safety Operations Example: Insignificant Units  Minor source for Title V, New Source Review  Ozone, PM nonattainment area  Compliance notice for failure to register cafeteria “char griller”  Facility registered unit and paid permitting fees; ongoing recordkeeping required8 © 3M 2010.

3M Environmental, Health and Safety Operations Pollution Prevention Pays (3P) Dr. Joe Ling launched 3M’s 3P program in 1975 “Pollution is … unused raw material. By reducing the amount of pollution, … [3M can] save money both on pollution control and on raw materials the next time around. Its a win-win situation.” Total Total Monetary Total Pollution Projects Benefit ($USD) Prevented (US lbs) 1975-2011 Totals 9,324 1.56 Billion 3.57 Billion9 © 3M 2010. All Rights Reserved.

3M Environmental, Health and Safety Operations Pollution Prevention Methods Method Description Product Reformulation • Replace a part of entire product with less or no toxic chemical(s) Process Modification • Alter a manufacturing process to reduce pollution (air, water, waste) Equipment Redesign • Redesign of equipment with new concept to reduce pollution Quality/Yield • Improve efficiency with reduced defects or use fewer raw Improvement materials to reduce waste Recovery and/or Reuse • Develop/Improve system to recover or re-use waste stream New Product • Develop product with environmental attribute/benefit to assist customer with reducing pollution10 © 3M 2010.

3M Environmental, Health and Safety Operations Summary  Minnesota air quality is good; changes to standards may trigger new requirements  Nonattainment risk  More requirements and complexity  Less flexibility and choice  Opportunities exist for all of us to proactively reduce our emissions15 © 3M 2010.
