SUBJECT:
AMBROSIA LAKE UMTRA SITE WASTE DISPOSAL RECOMENDATIONS Introduction 1
On July 11, 1990, the U.S. Department of Energy submitted a cover letter and report to NRC regarding wastes at its Ambrosia' Lake, New Mexico, UMTRA Project site. The Ambrosia Lake site is being decommissioned.and Phase'I_of the mill demolition has been completed.
During mill decommissioning, waste materials were analyzed and 168 drums,of. hazardous waste and other substances were;
.i segregated, based upon waste compatibility. The analyses were originally.
conducted by Southwest Hazard Control, Inc. and later by Hazchem Environmental a
Services, Inc.
The materials were placed-in: temporary storage onsite'and await final disposition.
MK-Ferguson Company (MK), DOE contractor for Ambrosia Lake, reviewed the laboratory analysis and presented the information in written form for review.
MK also recommended how the waste should be disposed of'according to its hazardous content.
DOE'has requested an NRC review and concurrence of this report.
Discussion i
The material to be disposed consists of three different types.of wastes. -The' first is waste that is hazardous but not radiologically contaminated.
The second type of waste is partly to completely radiologically contaminated..The PM:URF0$d PM:URF0 DD:URF AD: URF0:

2 AUG 301990 third type of waste is recyclable materials that are not radiologically contaminated.
A further breakdown of the waste is presented by categories in MK's report to D0E.
A brief summary is presented as follows:
1.
The following drums are not radiologically' contaminated but contain hazaraous properties or constituents:
4 drums of flammable paint solids 1
drum of pH 14 solution i
1 drum of waste grease subtotal 6
drums These wastes must be sent to an EPA permitted treatment, storage and
- disposal facility.
2.
a.
The following drums are radiologically contaminated and appear to be byproduct material as defined under Section 11(e)(2) of the Atomic Energy Act:
71 drums of radioactive sludge 26 drums of slightly contaminated cottonseed insulation 12 drums of radioactive organic liquid 1
drum of radioactive soil with < 2 ppm PCB 38 drums of radioactive trash =
one selenium rectifier Subtotal 148 drums and one selenium rectifier These wastes can be placed into the tailings cell under UMTRCA.
b.
The following drums are radiologically contaminated and contain hazardous properties that could. disrupt or compromise the integrity of the tailings cell:
5 drums of radioactive liquid pH 11 2
drums of radioactive sludge with lead and ignitability 1
drum of radioactive sludge with ignitability Subtotal 8
drums These drums should be characterized further for their possible impacts to ground water hydrology and cell compatibility.
The content of these drums must also-be defined as byproduct material or mixed wastes.

3.
The following drums are not radiologically contaminated:
5 drums of lead-acid automobile batteries i
1 drum of Matheson gas cylinders e-1 5 gallon pail of Ansul Purple K fire extinguisher powder Subtotal 6
drums plus one 5 gallon pail These materials should be recycled at the appropriate vendor.
4 Total 168 drums, one 5 gallon pail, one selenium rectifier '
There were no wastes characterized that would be classified as acutely toxic, although some of the wastes were hazardous due to extremestin pH'or 4
ignitability.
A majority.of the drums contain wastes that are not considered hazardous but are slightly contaminated by radioactive materials during _their.
I use in mill operations.
The materials contained in the drums under type 2b, drums 116, 118-121, 141, 142, and 173, should be further characterized to i
determine compatibility with and disposal in the tailings cell-byproduct materials.
Alternate disposal methods or disposal at EPA approved-locations-l for these possible mixed wastes should also be considered.
One drum of radioactive soil is contaminated with less than 2 ppa PCB, below' concentrations regulated by the Toxic Substance Control Act, and can be disposed of in the tailings cell as byproduct material.
The one 5 gallon pail of Ansul purple K fire extinguisher powder is probably not radiologically contaminated and should be recycled or-disposed of'in an-approved: landfill.
The selenium rectifier, as a former part of the mill structure, is considered byproduct material and should be disposed of with the demolition. debris in the tailings cell.
Conclusion The staff concludes that the disposal or recycling.of wastes as1 reported by MK-Ferguson Company's Waste Disposal Recommendations study is in-accordance with applicable federal regulations under RCRA and UMTRCA except for drums 116, 118-121, 141, 142, 173, and 128.
Drum 128 (5 gallon pail) of Ansul Purple K should be recycled and drums 116, 118-121, 141, 142, and 173 have hazardous constituents that could preclude their disposal in the tailings cell.
Further-analysis should be conducted on these drums to ascertain if they are byproduct material.
