SUMMARY
House Joint Memorial 8 addresses reclassifying the types of nuclear waste that will be stored at
the WIPP Project. This Joint Memorial request that ‘Greater than Class C’ (GTCC) nuclear
waste be allowed to be stored at the WIPP site. This Joint Memorial points out that transuranic
waste, another high level type waste, is currently stored at the WIPP site. The conventions and
safety procedures for storing both GTCC and transuranic are similar.
Radioactive wastes are waste types containing radioactive chemical elements that do not have a
practical purpose. They are sometimes the products of nuclear processes, such as nuclear fission.
However, other industries not directly connected to the nuclear industry can produce large
quantities of radioactive waste. For instance, over the past 20 years it is estimated that just the
oil-producing endeavors of the US have accumulated 8 million tons of radioactive wastes.
[1]
The
majority of radioactive waste is "low-level waste", meaning it has low levels of radioactivity per
mass or volume. This type of waste often consists of used protective clothing, which is only
slightly contaminated but still dangerous in case of radioactive contamination of a human body
through ingestion, inhalation, absorption, or injection.
In the United States alone, the Department of Energy states that there are "millions of gallons of
radioactive waste" as well as "thousands of tons of spent nuclear fuel and material" and also
"huge quantities of contaminated soil and water".
[2]
The NRC has categorized Low Level Waste (LLW) into four classes (A, B, C, and GTCC) based
on the concentration of specific short-lived and long-lived radionuclides given in two tables in 10
CFR 61.55. These waste categories are illustrated in the following table.

To be determined
Transuranic waste is defined as:
Waste containing more than 100 nanocuries of alpha-emitting transuranic isotopes per gram of
waste with half-lives greater than 20 years, except for high-level radioactive waste... All TRU
elements are heavier than uranium, have several isotopes, and are typically man-made. Key
radionuclides found in TRU waste include americium-241 and several isotopes of plutonium.
There is currently only one place in the United States accepting shipments of TRU, the
Waste
Isolation Pilot Plant
(WIPP). Other countries do not include this category, favoring variations of
High, Medium, and Low Level waste.
FISCAL IMPLICATIONS
There may be some added revenues for the State of New Mexico, resulting from actions relating
to this Joint Memorial.
SIGNIFICANT ISSUES
House Joint Memorial requests that the WIPP site be allowed to receive and store nuclear that
has higher levels of concentration than Class C nuclear waste (GTCC). This Joint Memorial is
based upon WIPP’s successful handling of transuranic waste in the past.
