1 Safer Products That Work Cleaners and Degreasers for Auto Repair State/Community Hazardous Material Source Reduction Jane Paulson October 25, 2017

2 Minnesota Technical Assistance Program Mission Statement: Strengthening Minnesota businesses by improving efficiency while saving money through energy, water, and waste reduction Based in the University of Minnesota School of Public Health Confidential, free and non-regulatory Staff of 12 scientists and engineers with 30 years assisting business through: Site assessment visits Intern Program Company team facilitation Demonstrations & research projects Minnesota Materials Exchange Website, fact sheets & case studies

3 Why Industrial Maintenance and Automotive Repair? Most businesses perform degreasing for equipment maintenance or production processes 7,738,000 lb VOC emissions from area sources in MN 5% of Industrial/Commercial VOC emissions Common methods Aerosol degreasing cleaners Manual parts washers

4 What is better? Does the product work? No Hazardous Air Pollutants (HAP s) Low Volatile Organic Compounds (VOC s) Low Ozone Generator (lbs.o 3 /lbs.product) Minimize MN Chemicals of Concern Do a comparison!

5 How do I find safer products? TURI Check out their Cleaner Solutions Database Look for reputable labels: EPA s Safer Choice Label Green Electronics Council - EPEAT USDA Organics

13 Parts Washers Aqueous parts cleaners can replace solvent based parts washers or other cleaning products. Solvent-based City of Minneapolis & MPCA are partnering with Safety-Kleen to offer a cost share program for aqueous-based parts washers Covers 45% of upfront cost and service Other parts washers we have seen success with include SafeWasher by Cintas, Superclean AP by Cuda and Ozzy Juice by Chemfree. Aqueous-based

14 General Structure of Projects Introduce the project and get agreement from business to participate Identify current products and suppliers Assess products Identify potential alternative products Provide samples Test samples If company agrees to make a change, provide a case of product to get them started

15 Round 1: Auto repair and industrial maintenance pilot projects Outreach to MN auto repair and industrial maintenance facilities Assess product use at industrial/automotive businesses Identified safer alternatives Companies trialed grant purchased sample of new product MnTAP provided hands-on technical support 23 facilities conducted trials/12 implemented change 3,030 lbs VOC, 760 lbs HAP, 650 solid waste, $7,470 savings EPA SRA Grant Project X9-00E

16 Demonstrating and Trialing Products Potential replacements have to work for the process! With trials, observe how the trial product compares to the current product Time it takes to do the job Does it leave any unwanted residue? Can you use the same method? (type of rag, force needed to clean, etc) Overall, can you achieve the results required for the job?

18 Round 2: Duluth Degreasing Blitz Air Quality Project for Duluth, Minnesota, EPA Making a Visible Difference in Communities Identified sites using the Mergent Intellect Database and developed a batch-geo road map for accomplishing the site visits. Needed to be fast due to travel constraints 50 shops visited in two days 32 Businesses sampled product, 16 redeemed vouchers, 10 sites implemented change 1700 Pounds of VOCs, 660 Pounds HAPs EPA CEP Grant Project X9-00E02031

19 Vendors and Samples Worked with local suppliers in advance to get buy-in Advanced Auto Parts O Reilly Auto Value Put together a product list Acquired samples Created vouchers.

20 Blitz Assessments Quick Intro University of Minnesota Project on brake cleaners Offer a free case of brake cleaner. Goals: reduce VOCs, chemicals that contribute to air pollution HAPs, chemicals that can have adverse effects on human health Collect information Type of brake cleaner used Quantity Preferred vendors Provide sample product and voucher Follow up by phone within a month to learn how the safer product worked.

21 Round 3: Phillips Community Small Automotive Businesses The Phillips community is an area of Minneapolis with high concentrations of environmental impacts. A MnTAP intern was based at a community partner to work with small businesses. Partnerships with business groups were helpful in building trust. Short initial contact Provide samples after assessment Quick in-person follow up Contacted 24 shops 14 participated, 11 made changes 430 lbs HAPs, 840 lbs VOCs EPA SRA X9-00E02051

22 Overall Outcomes 89 facilities engaged/informed of safer products 55 facilities conducted trials 22 facilities implemented change 4700 lbs VOCs eliminated 1400 lbs HAPs eliminated 650 lbs of solid waste by changing to bulk products $7,740 per year in savings for businesses

23 Key Learning - Engagement Providing trial product critical to engagement Community partnerships help build trust Not easy for facilities to choose safer products Simple messaging is important Avoid technical jargon Focus on human health risks - especially exposure to HAPs Helpful to explain that sample products have tested positively with other sites Quick visits are good, showing that you understand their time constraints Follow-up soon after visit (within 1 week recommended)

24 Key Learning - Formulations Acetone the VOC Exempt alternative There were some complaints about smell and headaches wt% was a threshold where complaints increased Common that employees don t use any PPE when degreasing Avoid HAPs Toluene, xylene, ethylbenzene, and methanol were most common Adding 5-10% to increase cleaning power in 90% Acetone mixes is still 5-10% HAPs Citrus cleaners were not recommended d-limonene is a VOC, MIR = 4.55, acute aquatic toxicity Perception is that if it smells like oranges, its okay because its natural One alternative may not work for every job partial change is still an improvement

25 Key Learning Bulk Products Pressurized streams are preferred at most shops Benefits Bulk products are usually much cheaper than aerosol products Reduce packaging Eliminate propellants, which also may be VOCs Obstacles Often only available in 55 gallon drums Too much inventory for small businesses Difficult to transport May create reporting obligation, hazardous waste generator Upgrading from bulk cleaner to the safest bulk cleaners is often a big price increase

26 Key Learning - Working with suppliers It is helpful to get suppliers on board Suppliers may/may not stock safer products Education is needed. Many of the best options are formulated for California. Some suppliers think these products cannot be sold elsewhere. Pricing and supplier relationships are big Shops may get a great deal if they have one supplier for all products

27 What s Ahead- Round 4: North Minneapolis North Minneapolis is another area with higher than average air quality impacts. Grant funded by Minnesota Pollution Control Agency Plan to work with a variety of businesses, automotive and industrial Engagements will be by MnTAP staff, with a format similar to Phillips intern project Preparation in progress now, outreach and trials at businesses planned for late fall 2017-spring 2018.
