Dear Bill:

'As you requested, I am forwardingupl}e Stiatc df Rhode Island's comments on the OAU Proposed RadiM6fiqal'"S[urvey Plan for UNC 1
Recovery Systems.
I have requested large scale aerial photo-graphs of the site and will, as we discussed this morning,. mail these to you on receipt.
On an unrelated matter, as you know, we recently reviewed test data from NRC, USGS, UNC and our own lab on the UNC deep well.
We found that data to be very disappointing due to the wide dis-crepancies in values reported and feel that periodic follow-up testing is necessary.
It is my understanding that follow-up testing af the water tabic down to bedrock would require drawing samples from four sampling stations in three UNC wells already in place.
These are, the original deep well (DH 1-1) drilled by Goldbert-Zoino, a near-by deep Barcad well also drilled by Goldberg-Ziono, and UNC's T-6 shallow monitoring well.
Periodic testing of samples drawn from the 45-55 foot station in T 6, the 72.5-74 Foot station in DH 1-1 and the 88.5-90 and 110-111.5 foot stations in the deep Barcad well would provide reasonably complete vertical profile of the contaminant plume.
I will be contacting UNC officials to gain their voluntary coop-eration in sampling these three wells with samples to be split between UNC, NRC, USGS, EPA and the State.
I am hopeful that such cooperation will be forthcoming.
However, it would neverthe-less seem appropriate giver NRC's need for accurate information on the contaminant piume for your agency to require periodic monitoring

Mr. William drow Page Two August 27, 1981 of the type we propose as part of UNC's license.
No would, therefore, urge you to amend the license accordingly.
A copy of our comments on the OAU Survey Plan is attached.

STATE OF RHODE ISLAND COMMENTS ON:
0AK RIDGE; ASSOCIATED UNIVERSITIES " PROPOSED RADIOLOGICAL SURVEY PLAN" FOR UNC RECOVERY SYSTEMS, WOOD RIVER JUNCTION GENERAL:
E 1.
It would be extremely helpful for 0AU's Survey Plan to be superimposed on a large scale aerial photograph of the UNC site so that we could better appreciate the nature and extent of surveying proposed.
We will be-forwarding such a photo-graph to NRC.for this purpose.
2.
It would likewise be helpful for all concerned to have a face to face' discussion of the survey plan once the plan is represented graphically as suggested above.
SPECIFIC:
1.
Purpose (Pg. 1):
It is our understanding that the immediate purposes of the proposed survey are to assist NRC in designing an appropriate decontamination strategy for UNC Recovery Systems and to verify that outlying areas of the site-meet applicable standards.
This would appear to be some-what different from the purpose set forth by OAU.
Clarifica-tion is requested.
,2.
Site Description and History (Pg. 1):
In addition to the i
l unirradiated uranium scrap referenced, UNC also processed so called."slightly irradiated" scrap.
This should be noted.
3.
-Site Preparation (Pg. 3):
No rationale is given for the choice of a 15.25m' grid frequen.y or the setting of a 61m sampling perimeter around the restricted area.
Such a o
rationale is-needed.
4.
Surface Measurements (Pg.
2, B-1):
It is our understanding that the walkover surface scan referenced will be of 100% of the griddled area and will not be confined to grid lines or intersections.
We request ccnfirmation of this understanding.
5.
Surface Measurements (Pg.
2, B-2 and 3):
Gamma exposure and Beta-Gamma radiation levels at all points above background should be measured and recorded as well as at grid inter-sections.
6.
Surface Measurements (Pg.
2, B-4):
Again, it is our under-standing that walkover surveys of roads, etc. will be of 100%
of the area described, even though levels will only be recorded at " hot spots" or 300 meter intervais.
Clarification is needed.
7.
Surface Measurements (Pg.
2, B-5):
A 100% walkover survey of all vehicle accessible areas on the UNC site should be con-ducted since it would be in such areas that one might expect abandoned burial sites.
Measurement and recording of radia-tion levels only at intervals or where " hot spots" are identi-fied is acceptable.
8.
Surface Sampling (Pg.
3, C-1-b,c):
The grid frequency and sampling points in known disposal areas and "hrt spots" identified by walkover survey should be considerably denser than proposed given the relatively small size of the areas involved.
We would suggest a frequency of three meters.
9.
Subsurface Measurements (Pg. 3-1 and 3):
The technology and capacities of " ground penetrating radar" should be briefly described.
m e, 4
Samples should be obtained at a grid frequency of 3m in previous' disposal areas, other suspect areas, the septic tahk drain field and near the waste lagoons.
Samples should be collected at 10, 20 and 30 feet below the ground surface and subjected to gamma spectrometer analysis.
10.
Baseline Sampics:
We believe the reference to "dr nwind" sampling should read " upwind."
In addition, given the vagaries of wind directions in southern Rhode Island, collec-tion' points should be at some distance from the plant site to provide an accurate baseline.
11.
Analysis of Samples:
Strontium 90 and related fission by-products have been identified in UNC's waste storage lagoons and in the contaminated plume extending from these lagoons.
Soil, water and vegetation should be tested for all radio-nuclides identified in the lagoons and/or groundwater con-taminant plume.
