2. Today’s Topics Hartford Iron site assessment Cleanup to date Cleanup steps to come What can you do

3. This presentation summarizes information from The public record on Hartford Iron Available at the Indiana Department of Environmental Management’s Virtual File Cabinet http://vfc.idem.in.gov/

4. Satellite View

5. Agreed Order March 2009

6. Violations Handling wastes in a way that creates a threat to human health or the environment Open dumping of automotive fluids, oil, fuel, battery acid, soil piles, and solid waste Inappropriate disposal of waste tires

7. Violations Open burning Storm water pollution Failure to submit required paperwork

8. Agreed Order Requirements Stop open burning Stop dumping Handle waste tires correctly Pay a $5,000 penalty

9. Agreed Order Requirements Site assessment If contaminants are found, Hartford Iron must remediate each contaminated area to closure

10. Site Assessment – sampling grid

11. Site Assessment – soil contaminants found above Indiana standards Above industrial closure levels: arsenic, benzene, benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, butylbenzylphthalate, copper, lead, thallium, toluene, total petroleum hydrocarbons, extended-range organics, and PCBs Above residential closure levels: Petroleum hydrocarbons, butylbenzylphthalate, naphthalene, 2- methylnaphthalene, antimony, barium, cadmium, mercury, nickel, selenium, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, and cyanide.

14. Example soil samples with high concentrations Contaminant In parts per million (ppm) Hartford Iron 2015 Resident Screening level 2015 Industrial Screening level Polychlorinated biphenyls (PCBs) AR 12427613.410 AR 124244.63.410 AR 1248933.410 AR 125440.81.510

16. PCB contamination triggered EPA involvement

17. Additional Requirements PCB soil remediation at Hartford Iron to 1 part per million (PPM) PCBs are not to exceed 0.1 ug/L (ppb) in storm water leaving Hartford Iron

18. Remediation to date Aug 2010 soil piles removed 2010 asphalt cap on the area of highest soil contamination (grids 23 & 30) 2011 dams and berms to guide storm water 2011 sediment traps at exits

19. Remediation to date 2012 holding tanks and filtration for storm water 2012Hartford Iron purchased 605 Chestnut St Oct 2015 excavation of grid squares 42 & 43

20. Remediation to date - summary Soil piles removed Asphalt cap over the most contaminated soil Partial control of storm water Partial excavation of contaminated soil

21. Remediation Still to Come Permanent storm water solution More excavation Ground water monitoring

22. What follows is environmental health information. It does not come from the Hartford Iron public record.

23. Contaminated soil is moved by wind, storm water, and vehicles

24. Contaminated soil can contaminate ground water

25. Recommendations Wash your hands before eating, drinking, smoking or feeding children Wash children’s hands and faces often, especially before eating Make sure any toy or utensil a child puts in his or her mouth is clean

26. Recommendations Keep windows and doors closed when it’s windy or when Hartford Iron is making lots of dust Remove shoes when entering the house Wipe dirt off of pets’ feet before they enter the house

27. Recommendations Wet mop floors and wet wipe surfaces frequently to remove dust Vacuum carpets, rugs and upholstery

28. Recommendations If you grow fruits or vegetables, wash them very carefully & consider testing your soil Wear gloves when working outside
