SUBJECT:

GROUNDWATER MONITORING

Dear Mr. Haughney:

r i

As requested by Mr. Glen L. Sjoblom's letter of December 13, 1989, enclosed l

is our plan for monitoring possible migration of radioactive material from i

the former burial site, evaporation ponds and the limestone fill areas at our Hematite site.

Routine monitoring for the ponds and limestone fill areas has been underway for several years and routine monitoring for the burial site has already begun, j

for monitoring of the burial site and the ponds, water samples will be taken from the wells, for monitoring of the limestone piles, the fuel

[

Cycle Safety Branch staff previously agreed that it would be appropriate to monitor surface runoff instead, and that this could be achieved by taking

[

soil sam;.les downhill from the piles, further details of the monitoring are enclosed.

Please advise if further information is required.

Respectfully submitted,

)

faQUND ilATER MONITORING AT THE HEMATITE NUCLEAR FUEL MANUFACTURING FACILITY I.

1.0 PURPOSE t

This report describes the program for routine monitoring of ground water for radioactive material at the Hematite Nuclear fuel Manufacturing facility.

It responds to the NRC request in Reference 1.

2.0 BAGfaQVHQ Three types of on site disposal have been practiced at Hematite.

They are sunnarized as follows:

f 2.)

Trench Burial

[

East of the fenced manufacturing area, unlined trenches 12 feet deep received a variety of materials contaminated with uranium.

Reference 2 is a radiological survey of this location.

Burial stopped about 20 years ago.

t 2.2 Evanoration Ponds South of the manufacturing area and inside the fence line two shallow evaporation ponds received SNM waste solutions from wet recovery operations.

Reference 3 describes these ponds.

Their use stopped about 12 years ago and the bottom sludge was removed to a licensed commercial burial site.

2.3 Limestone piles Spent limestone rock chips from fluoride of f gas dry scrubbers are piled in three locations on the Hematite site.

Reference 4 described the current status of these piles.

The residual radioactivity levels in the piles are within the levels in Option 1 of the Branch Technical Position Paper that would allow unrestricted release.

3.0 MONITORING All three types of disposal areas have been monitored to various extents for years.

Each area differs in the characteristics and level of contamination and therefore in the appropriate monitoring plan.

The l

proposed monitoring represents an extension to past monitoring and is presented in the following for each area.

3.1 Burial Site Monitorino in As part of the extensive radiological survey described in Reference 2, shallow wells were drilled to obtain groundwater samples.

The wells are located (figure 1) southeast of the burial site, downhill toward the creek near the east border of the plant site.

Two of these wells will be used for routine sampling.

In addition another well will be drilled toward the south during the summer of 1990 after the wet spring weather.

Monthly water samples will be taken and gross alpha and beta counting done.

Routine sampling from the existing wells began in January, 1990.

e O'

4 3.2 Monitorina of Evaporation Pordi F

Reference 3 describes the placement and 'jesign for three monitoring wells south of the location of the former evap3 ration neds.

The wells were

)

located (figure 2) to provide data on distance anc lateral dispersion. of contamination from the ponds.

Their location is downhill from the ponds towards the Joachim Creek that is the south easterly boundary of the Hematite plant site.

A historical record of monthly samples from these

+

wells is available starting from 1978, and monthly sampilng will continue.

Alpha and beta counting will be done.

l 3.3 Limestone Pile Samolina t

L Reference 4 describes three locations of limestone piles (figure 3).

1 Routine quarterly soil sampling at the downhill edge of piles labeled A and C began in 1985 and will continue.

Alpha and beta counting is done.

Soil i

sampling provides a trend in the water runoff contamination that is a better indication of potential migration for this insoluble Material than might be obtained by water sampling from downhill wells.

Hematite has requested (Reference 4) release of Pile B for use as fill material on site, as with Piles A and C.

Monitoring of Pile B innterial will depend on the response to this request.

P 4.0

SUMMARY

i A historical record exists of radiological sampling from all the disposal sites at llematite.

The proposed addition of one well and the continuation of now routine sampling provides trending that can determine migration from the disposal areas.

The following table summarizes the monitoring plan.
