PURPOSE:

l The purpose of this meeLing was.to. complete. technical planning.for the f

additional off-site investigations of.the migration of tritium from the Sheffield site. These studies.we m agreed to by.the State of Illinois 16,1982 (quently ordered by state circuit courtcopy of. agreed. ord and U.S. Ecology and were subse on Tuesday, February AGENDA:

An agenda for the meeting, prepared.by U.S. Ecology and agreed to by all.

parties, is attached as Exhibit.2..

DISCUSSION:

j February 24, Wednesday:

I As indicated in the agenda, a steering committee was established to follow the program and evaluate the data generated in the additional off-site investigaticrts.

The steering committee will consist.of one representative from each of.the.

participating entities as follows:...

Howard Chinn, Office of Attorney General....

David Ed, Illinois Department of. Nuclear _ Safety Ron Gaynor. U.S. Ecology.

l TomJohnson,IllinoisStateGeologidal' Survey Buck Foster, U.S. Geological Survey David Siefken, U.S. Nuclear Regulatory. Commission U.S. Ecology agreed to be the focal. point for collection.and dissemination of l

all data generated by the various entities.,I indicated that.the NRC should receive two sets of d'ta, one.sent.to Jim Shaffner, WMLL, and one sent to Marty Schumacker, Region III..

Under the subject of a status report on property. leases.or acquisitions, i

U.S. Ecology indicated that initial. discussions have been made with the,

appropriate property owners. No agreements on leasing.and purchasing the property have been reached, and U.S., Ecology. lawyers are performing.a title search, including mineral and. gas rights, since any. acquisition must_ include all rights to the pmperties...

Access to these properties may.be.available.through the previous USGS agreements with the landowners. This will.be pursued.by.the USGS. The State of. IlMnois.

will research condemnation and.other options.for access.or. acquisition..

The question of access or acquisition.seems.to be.one of.two. major. hurdles.to implementation of the planned additional. investigations.to the. east of the. site.

The second major hurdle appears.to be one of transferring U.S. Ecology. funding.

i i

for the studies to the various.perfonning. organizations..,

Under the subject of technical. data. exchange,.each participating entity requested specific data that.they need_which.has.not.been.previously available.

i For example, I requested copies _of boring records from the USGS of all wells l

completed since the open file. report 75-1545_was. published (Exhibits. 3 and 4).

These records are part of a report.in.ppparation.but.are needed now for i

evaluation of ground-water migration from.the. site.

j i

Under the subject of review of, existing data.and studies in progress, Buck Foster i

gave a presentation using drawings showing:.

i

}'baseofsandunit t

upper surface of sand. unit thickness of sand unit l

potentiometric surface map.

l i

In addition, the results of an. ISGS electrical resistivity study to detemine l

the location and thickness of,the sand, unit were discussed. These data and interpretations served as the. basis for defining the additional studies included in the agreed order....

t Two points of special interest are the. possibility of.a. permeable channel in.

l the sand unit which serves as_a. linear Pain.(as. suggested by the potentiometric i

surface map) and an apparent thickening.of the sand, unit.to.the southeast from well 563 (as suggested by the. electrical. resistivity survey).. It was. agreed that, as part of the additional studies,_the ISGS.would perfom a ground.

temperature survey and repeat the electrical. resistivity survey at closer i

spacing to study these two observations.._.

l t

A third point of special interest,is the, projection,: based on.available. data, that the sand unit may be unsaturated at the. east, ends of trenches 23, 24, i

25c, 26, 1 and 2.

This will. affect.the construction of any.new wells in the area since they will be screened below.the sand.in the Tenneriffe. silt.or.

i Hulick till.

It also implies that.any releases.from these trenches would.,

initially move through a fine-grained. cohesive. soil before. entering the sand l

unit further to the north or east.. This,would. provide reduction in concentra-tion due to low ground-water velocity, sorption of. reactive solutes, and,.

dilution when entering the sand unit..

~.

With respect to the additional wells.to.be. drilled.to.the. east nf_the site, l

l the USGS showed the pmposed locations antindicated.that_these.should be.

re-evaluated as drilling proceeds... Wells.will.be_ sampled for. tritium.after drilling, prior to and during.; development..and.after completion.

j Wells will be drilled in the lame. manner as wells.560 through 576._.A.USGS.

.l drilling rig and crew from Den er.. Colorado.can.begin work on.approximately March 22, 1982. The only change.in well.. construction.will be_the use.of PVC.

..l l

well screens, rather than stainless.. steel well,. screens, if aya11able..

i It was agreed that the drilling would.be.perfomed in. stages, with 6 or 7 wells in the first stage to define.the extent of migration and concentrations of tritium. The second stage.will consi::t of 3.or 4 wells near.the east security fence to define the source of the. tritium, and the third stage l

(If necessary) would consist of.2 to.4. wells ahead of.the tritium plume to l

monitor its migration.

The tritium is viewed as primarily significant.as.an indicator of rigration.

Sampling for radioisotopes other than. tritium.will be performed only in wells showing significant levels of, tritium. These analyses would include gross cipha, beta and gama. Should these show significant results,_ isotopic anclyses.may be performed.

February 25, Thursday:

i y.

It was agreed that the steering comittee would get together for an up-date meeting 'atl13:00 a.m. on Friday, March 26, 1982 in. Urbana, Illinois. Subse-quent discussion centered on the. anticipated schedules for the work to be performed.

i I

The ISGS indicated the electrical resistivity and. temperature surveys.could start in' late March after the. frost is out of the ground. Tlie. studies should be completed in several weeks.. The.USGS drilling is projected.to start approximately March 22, depending on. delivery of supplies, access, and transfer.

of funds. The first stage of borings should be completed within two weeks, with laboratory testing and sample description.taking another 2.or 3 weeks.

Arrangements for disposal of possibly tritiated. soil. cuttings and water from the additional wells were discussed...U.S. Ecology is very concerned that normal drilling and development procedures will. result in very low levels.

of tritium on the ground which might. interfere with their environmental monitoring. Discussions will continue on disposal of soil and water.

or the IGS to have final authority as to the drilling program L

and the State of Illinois to have the final authority as to the monitoring and testing program.

USEC shall pay for the cost of the aforesaid pro-gram; provided, however, that no such program having an estimated cost to USEC in excess of $100,000 shall bb re-quired unless and until approved by USEC or by a subsequent order of this Court.

The parties recognize that the State estimates that the. cost of this program to be $150,000; how-ever,' the parties agree to use their best efforts to imple-ment program modifications to reduce the cost to less than

$100,'000 without reducing the quality and effectiveness of the program or. increasing the cost thereof to the State.

e g

g All data generated from the program herein required shall be made equally and promptly available to the State and USEC and to their respectipe. designees.

The results of the program herein required shall be. reported to the Court pursuant to Paragraph 8 hereof.

2..

Should migration off the Sheffield site of,any~

radionuclides other than tritium be decected by either party, that fact shall promptly be reported to the other party.

Should the'first 8 wells. drilled off the site pursuant to the program described in Paragraph.1 hereof disclose no Tritium in excess of 1.0 nCi/1,'USEC may petition to the Court to terminate said program.

3.

USEC shall take all steps reasonably necessary to obtain, by lease or other appropriate agreement, immediate

~

control over all that real estate now, and from time-to-time, necessary to permit the monitoring and' testing required by Paragraph 1, to permit continued monitoring of all existing U'.S.G.S. off-site wells and to, control all ground found to l

be contaminated-by tritium migration in excess of 1.0 nCi/1, all to the ends that (a) the State and its designees shall have. free and ready access to such prope,rty,for'the performance of.such, drilling, testing, monitoring, control or other pro-grams as may b'e appropr,iate; (b) no private wells shall be
