2. #1 To be “hazardous waste” Definition Compatibility Collection Tracking Labeling Segregation SAAs Moving it out It must be waste. Pretty simple. It it’s not waste, it is NOT hazardous waste, and hazardous waste rules do not apply.

3. #2 To be “hazardous waste” Definition Compatibility Collection Tracking Labeling Segregation SAAs Moving it out It must be hazardous (by EPA definitions) hazardous by (i) characteristic • ignitability • corrosivity • reactivity • toxicity or (ii) listed by name or by source in hazardous waste regulations

4. IS IT WASTE? Definition Compatibility Collection Tracking Labeling Segregation SAAs Moving it out (Waste = material intended for disposal)

5. IS IT HAZARDOUS? Definition Compatibility Collection Tracking Labeling Segregation SAAs Moving it out A. by possessing a characteristic defined by EPA • ignitability • corrosivity • reactivity • toxicity or B. on any EPA list. examples: F003 listed waste is “any waste mixture containing 10% or more xylene, acetone, ethyl acetate, ethylbenzene, ethyl ether, methyl isobutyl ketone, n-butyl alcohol, cyclohexanone, methanol, or any combination P077 listed waste = “unused p-nitroaniline”

6. table 2.2 in hwdg.pdf “Characteristics” in detail Definition Compatibility Collection Tracking Labeling Segregation SAAs Moving it out • Corrosive: pH >12 or pH < 2.5 • Ignitable: 4-part definition which includes most strong oxidizers! • Reactive: 8-part definition focuses on reactivity with air or water producing flammable, high energy, or toxic gas. • Toxic: leachate from TCLP test (EPA method 1311) contains toxins in the D004 – D043 list.

7. Evaluate compatibility of wastes BEFORE mixing them together. As is possible, neutralize strong acids/bases, react reactives, reduce oxidizers, oxidize reducing agents…. AS A DESIGNEDPART OF YOUR PROCESS. Definition Compatibility Collection Tracking Labeling Segregation SAAs Moving it out

8. Collect in appropriate and compatible containers; • Acids typically dissolve metals. • Some solvents dissolve some plastics. • HF and strong caustic etch glass. • Don’t mix radioisotope and chemical waste. • Keep all mercury separate.

9. If wastes are co-mingled in the lab, a log sheet should be used to track contents of each container. Definition Compatibility Collection Tracking Labeling Segregation SAAs Moving it out • All “ingredients” must be logged, • so that EPA-regulated items will be named, waste “characteristics” made obvious, and • compatibility questions answered.

10. Toxic characteristic chemicals names must always be noted. • (table 2.2 in hwdg.pdf) Definition Compatibility Collection Tracking Labeling Segregation SAAs Moving it out

11. Toxic characteristic chemicals names must always be on container label. Definition Compatibility Collection Tracking Labeling Segregation SAAs Moving it out • Any trace of any of those chemicals must be mentioned in the waste name; “chemical description” on the pickup form and “contents” on the waste label.)

12. Manufacturer’s label is adequate if you are disposing unwanted amount. • For chemicals & mixtures not in manufacturers’ container, label with: • Contents - no abbreviations,no symbols, no formulae. • Percentages must add to 100%. • This orange label is not required, but is widely recognized and used. Definition Compatibility Collection Tracking Labeling Segregation SAAs Moving it out

13. Segregate waste containers as for any chemical storage: • Acids separatefrom Bases • Oxidizers not near organics • Water-Reactives awayfrom water Definition Compatibility Collection Tracking Labeling Segregation SAAs Moving it out

14. Satellite Accumulation Areas Info and rules here http://www.purdue.edu/rem/hmm/wststo.htm and http://www.purdue.edu/rem/home/booklets/hwdg.pdf Definition Compatibility Collection Tracking Labeling Segregation SAAs Moving it out This is more of an “advanced topic” and most research groups do not have SAA’s. If you do, however, this is important stuff.

15. Making it go away. On Pickup Form • Fill out correctly, neatly, legibly. • Questions? Call 40121. • Labels must match pickup request names. Definition Compatibility Collection Tracking Labeling Segregation SAAs Moving it out In the Lab • Sealed, clean, correct containers. • Area and waste safe for REM people.

16. SO MANY RULESSo Many Different Cases • Friendly folks at REM-HMM will answer all questions. • And then you do what they say. • If a new or changed situation arises, ask more questions • Return to step 1. Definition Compatibility Collection Tracking Labeling Segregation SAAs Moving it out 40121

17. Open the pickup request attachment in another window and this is #1 of three pickup request lines you are to complete, save, and re-upload. 1. This one gallon jarcontains three broken mercury thermometers, with some paper towels and a couple of gloves. Write a line on the waste pickup request for it.

18. Pickup request continued 2. There are three 1 lb bottles of unused, unwanted sodium thiosulfate. Write a second line on your waste pickup for these.

19. Pickup request continued 3. Waste container (4 L) log sheet says: Write a third line on your waste pickup for this. Use integer percents.

20. That’s it. • After completing the waste pickup, save it and upload it.
