Jc MEMORANDUM FOR: F. J. Congel, Chief Radiological Assessment Branch, NRR FROM: C. J. Paperiello, Chief Emergency Preparedness and Radiological Protection Branch, RIII

SUBJECT:

CONTAMINATED SOIL AT BIG ROCK POINT In May 1984, Consumers Power Company reported that an unmonitored liquid release to onsite soil had occurred at their Big Rock Point-Plant. The release was from a. leak in a two-inch diameter underground pipe which carries demineralized water to the condensate storage tank. The licensee estimated that about 5 millicuries, primarily cobalt-60, manganese-54, cesium-134, and cesium-137, remain in the soil surrounding the leaking pipe. The leaking pipe h'as since been repaired.

In July 1984, Region III reviewed this matter and asked the licensee to contact NRR regarding final disposition of the radioactive soil. During a September 1984 inspection, it was found that the licensee had not contacted NRR regarding this matter. At that time, Region III again informed the licensee that they should contact NRR in accordance with 10 CFR 20.302 to request permission to dispose of the radioactive soil by leaving it in the ground. The licensee agreed to this, but retracted their commitment after concluding that since radioactive release to unrestricted areas (migration to Lake Michigan) would be within the limits of 10 CFR 20.106, the requirements of 10 CFR '

20.302 do not apply.

-We~ request that you review this matter to-determine whether a request by the licensee in accordance with 10 CFR 20.302 is required. We have attached a licensee event report and letter from the licensee to Region III to assist with your review.

APR 11 1985 EFBranagan JJSwift RFonner, BLD MEMORANDUM FOR: C. J. Paperiello, Chief Emergency Preparedness and Radiological Protection Branch, RIII FROM: Frank J. Congel, Chief Radiological Assessment Branch, NRR

SUBJECT:

CONTAMINATED SOIL AT BIG ROCK POINT This is in response to your memorandum of March 14, 1985, in which you asked that we review the matter of the contaminated soil at Big Rock Point with regard to the need for the licensee, Consumers Power Company, to request permission under 10 CFR 20.302 to dispose of the material by leaving it in place. We have considered the information provided with your memorandum and conclude the following:

The licensee has licensed material, byproduct material, in a location

~

1) and form where it is not secure (e.g., against the weather). Even though the NRC might find, after review of the circumstances, that leaving the material in place is satisfactory with regard to .the public nealth and safety and with regard to environmental impacts, the licensee cannot unilaterally make such a determination. The licensee must do something about .the disposition of the material; .

the choices are either to excavate the material, package it and ship it to a licensed burial ground or to request pursuant to 10 CFR 20.302 approval of a procedure to dispose of it in some other manner, e.g., by leaving it in place.

2) Including the estimated total quantity of radioactivity as released effluent in their second half 1984 effluent report does not relieve the licensee of responsibility for the proper disposition of the licensed material, the majority of which remains in place in the soil. Even though weathering and leaching may deli'ver some of the l radioactivity to Lake Michigan within seven years, some will remain i in the soil at the location of the leak; it continues to be licensed material for which the licensee is responsible.
3) For purposes of determining compliance with 10 CFR 20.105 and 20.106, the licensee is responsible for accounting for releases of radio-nuclides to the environment, e.g., to Lake Michigan, in the time ,

periods in which they actually occur. si g%

4) Section 30.14, Exempt Concentrations, is not applicable to these circumstances; the licensee was not given specific authorization to introduce the byproduct material into the soil. Our applicable regulations,10 CFR 20 do not provide lower limits to concentrations and quantities for which licensees are responsible.

If there are further questions on this, please contact me.
