Designation

Designation

“What shouldn’t go in the dumpster”


What is designation why do i care

What is designation? Why do I care?

  • Waste codes drive counting

  • Counting determines generator status→rules

  • Rules determine →disposal options, waste management costs

D001?

F003?


What makes a waste dangerous aka criptt

What makes a waste dangerous?(aka CRIPTT)

  • Corrosive

  • Reactive

  • Ignitable

  • Persistent

  • Toxic (Federal)

  • Toxic (WA State)


Two ways to designate waste

Two ways to designate waste

Generator knowledge

Testing


Generator knowledge

Generator knowledge

  • What processes/steps created the waste?

  • What raw materials went into those processes?

  • What does the MSDS reveal?

  • What percentage of each material could be in the waste?

  • MSDSs have limitations


Limitations of msdss

Limitations of MSDSs

  • Made for safety reasons, not waste disposal

  • Describe the product, not the waste

  • Processing may cause chemical changes

  • Volatile chemicals may be gone (check flash point)

  • Chemicals may not be listed (proprietary knowledge)

  • May not be made from test results


Waste testing

Waste testing

  • Use/document representative sampling methods

  • Test it yourself or know what tests need to be run

  • Determine tests needed (WAC 173-303-110)

  • Talk to lab about procedures


Online designation tool

Online Designation Tool

  • You can use the new online designation tool

    www.ecy.wa.gov/programs/hwtr/manage_waste/des_intro.html

  • Works through chemicals in waste one-by-one

  • Help available from regional contacts

  • Not for usable products


Online designation tool cont

Online Designation Tool cont.

  • You will need:

  • Excel 2007, 1997, 2000, 2002 (XP), or 2003

  • Names or Chemical Abstract Numbers (CAS) for each chemical in the waste

    • Tool includes lists of toxicity data and characteristics, sortable by name and CAS

  • Separate Excel worksheets for each chemical in the waste

Practice 1 designate barrier coat red primer

Practice #1Designate barrier coat red primer

  • 8 cans of unused red primer

    • Primer is not useable or returnable

    • Has been through several freeze/thaw cycles

  • Print from the Appendix folder:

    • Designation Checklist

    • Material Safety Data Sheet (MSDS) for red primer

  • Have copy of WAC 173-303 to refer to


Solid waste wac 173 303 016

Dangerous wastes

Solid wastes

Discarded materials

Solid wasteWAC 173-303-016

  • If you are throwing it away, planning to throw it away, or abandoning it in the “bone yard,” it’s probably solid waste.

  • Don’t let the word “solid” fool you – do the dumpster test.


Excluded waste wac 173 303 071

Excluded wasteWAC 173-303-071

  • Wastes excluded because:

    • generally are not dangerous waste,

    • are regulated under other state and federal programs,

    • or are recycled in ways which do not threaten public health or the environment

  • Such as:

    • Domestic sewage, permitted industrial wastewater, household wastes, agricultural crops, irrigation return flows, roofing tar, shingles, samples, etc.

  • Seven pages of exclusions


Discarded chemical products wac 173 303 081 wac 173 303 9903

Discarded chemical productsWAC 173-303-081, WAC 173-303-9903

  • Must be “Product,” therefore unused

  • Must have single active ingredient (per definition in -040)

  • Pcodes more toxic

  • U codes less toxic

  • See lists at end of rule

  • Use CAS number

    • Chemical Abstracts Service


Discarded chemical products cont wac 173 303 081 wac 173 303 9903

Discarded chemical products (cont.)WAC 173-303-081, WAC 173-303-9903

  • Does the MSDS show a match to P or U codes?

  • If there is a match, does that mean you have found the proper code?

  • Remember – must be unused and single active ingredient


Source wastes wac 173 303 082 wac 173 303 9904

Source wastesWAC 173-303-082, WAC 173-303-9904

  • Non-specific sources: F codes

    • 28 different codes

    • Read carefully

  • Specific sources: K codes

    • Particular industrial source


Source wastes cont wac 173 303 082 wac 173 303 9904

Source wastescont.WAC 173-303-082, WAC 173-303-9904

  • Is there an F code or a K code that would describe the red primer?

  • Read the code descriptions carefully.

    • Some have several qualifications that the material must meet before you can assign that code.

  • Refer to definitions in -040

    • (For example, “spent”)


Source wastes cont wac 173 303 082 wac 173 303 99041

Toxicity beyond question 8

Toxicity - Beyond Question #8

  • Can I stop at question #8?

  • MQGs and LQGs can stop

    • Stringent disposal rules

    • Encouraged to continue – for full knowledge

  • SQGs must designate for State Toxicity

    • Less stringent disposal rules

    • Questions 9 and 10


Washington state only toxic wt01 02 wac 173 303 100 5

Washington state-only toxic (WT01, 02)WAC 173-303-100 (5)

  • Poisonous

    • Kills fish, rats or rabbits

  • Two ways to determine

    • Bioassay - Expensive

    • Book designation

      • Use weight percentages

      • Determine equivalent concentration


Book designation wac 173 303 100 5 b

Book Designation WAC 173-303-100 (5) (b)

  • This is the formula to book designate waste.

    • Must know chemicals and weight %

    • EC = equivalent concentration

  • If EC > 1.0% =waste isWT01

  • If 0.001% ≤ EC < 1.0% = waste is WT02

  • If EC < 0.001 waste is not dangerous waste

Practice 2

Practice #2

  • A fork lift runs over the 8 cans of red primer, spilling paint everywhere. After it dries, the janitor cleans it up using ZIP STRIPTM

  • Does the resulting sludge designate as dangerous waste?

  • Assume all red primer constituents except red paint pigment has evaporated. Residual pigment is not dangerous waste.

  • Determine federal and state waste codes.

Designation

Is spent Zip Strip™ WT01 or WT02?

You call a hazardous waste specialist at the Ecology regional office. That person gives you this data to help determine the state toxicity category.

Conclusion

Conclusion

  • Work through designation step by step

  • Call your regional office for help

  • You can get ahead of the process. Designate chemicals before they come into your business. Avoid the chemicals that could cause your waste to be Dangerous Waste
