FW: [ RadSafe ] Recommendations on testing unknown waste

Fri Aug 17 08:18:40 CDT 2007

Just wondering, are there any other states that have extended this rule
beyond the NRC definition?

its not whats in the rules, its their interpretation. Several years ago,
the UT system asked for an interpretation that was far broader than the
rule. The rule says the same thing as the NRC. The letter the agency
sent back to UT allows the use of <.05 for almost any type of waste.
debris, paper, liquids, almost anything.

Bob,

I don't know if agreement states, other than Texas, have extended the

NRC exemption to cover more than those two waste types, but in general,

for the rest of the nation it applies to biological tissue and

scintillation material.

In fact I've never actually read Texas' version of this NRC regulation.

Can you copy it or give us a link to it. 

Thanks

Bryan Kirk

That definition only applies for materials within NRC jurisdiction

areas. As you are aware the state of Texas interprets that are far

broader than NRC and once a material is in Texas, Texas rules apply.

Bob,

While I agree with the characterization, I would put in a qualifier that

the H-3, C-14, I-125 <0.05 uCi/g applies to scintillation material and

animal tissue, per the NRC regs.

There are two ways to characterize a waste for disposal:  knowledge of

the process that generated the waste or analysis of the waste. If you

know how it was generated, you can then conduct analyses to confirm that

it is what you think it should be from the process it came from.  If

lots of persons simply poured a variety of unknown solutions into a

drum, you will have to do analysis of a representative sample. If its

multilayered, you may have to pull a representative sample from each to

properly characterize. The initial tests should be those for

characteristics. The results of those tests will tell you if you need to

do more.

If the nuclides are H-3, C-14, or I-125, annd the activity is less than

0.05 microCi/gm, you may be able to dispose as hazardous only without

regard to the radioactive constituents.

Your message doesn't provide enough of the specifics to be able to

properly assist you.

Dear RadSafers,

I would appreciate your input on this matter.  We have radioactive

liquid waste, for which we know the activity and isotope, but the

chemical constituents are unknown.  My question is two-fold.  One, how

would one go about testing for the chemical constituents?  Is there a

laboratory that you would recommend?  Two, do we need to find and list

each chemical component, or can we just test the liquid by

characteristic/listed traits, and ship it as such (i.e.: Radioactive

material, flammable, n.o.s)?

You feedback would be appreciated.

Sincerely,

Depends on where you are located.? EPA has granted so relief on disposal

and storage of mixed waste.? However California did not adopt that

ruling and you still have to treat as radioactive and hazardous.? All

storage and time limits apply to mixed waste in California.
