Subject:
Request to Dispose of Slightly Contaminated Chemical Cleaning Solution-inAccordancewith10CFR20.302(a)
Gentlemen:
t As requested in Reference (c), Maine Yankco is resubmitting.its application for disposal of slightly contaminated chemical cleaning solution inaccordance with 10 CFR 20.302(a). This submittal, for the. disposal of approximately 10,500-I__
gallons (about 200 fifty-five gallon drums) of chemical cleaning solution used in the cleaning of the secondary side of the. steam generators, has been modified to provide the information your office requires for review.
The chemical cleaning solution contains very low (but nonetheless measurable) concentrations of radioactive material, and quantities of metals'and chemicals that are categorized as hazardous by the EPA.
Since this waste contains low concentrations and a small-total quantity of radionuclides, Maine Yankee requests permission pursuant to 10' CFR 20.302(a) to dispose of this material as hazardous. waste in accordance with EPA regulations.
Disposal of this material as radioactive waste, if-deemed acceptable under low level waste disposal-site acceptance criteria, would-require solidification to a stable waste form, thereby increasing the disposal volume by a-factor of two'.
This option, even if. viable, is not consistent with the optimal use of the' limited radioactive-waste' burial volume available.
If approval under 10'CFR 20.302 is granted to dispose of this cleaning solution, Maine Yankee proposes ~to contract-Dupont Environmental Services, a company licensed by the EPA, to treat and dispose of this material as hazardous-waste.
It is our intent to have the waste transported, in truckload quantities, to the Dupont Chambers Works Waste Water Treatment Plant in Deepwater, New Jersey for processing and disposal as hazardous waste.

Attention: Document Control Desk Page 2 L
A radiological evaluation, based'on a 10,500. gallon (approximately 40,000 7
i
- liter) total-inventory whose specific activity is assumed for evaluation purposes
~
L to be the highest of any batch in the inventory, has been completed. _ The evaluation consists of dose estimates for disposal as-hazardous waste and a comparison to both 10 CFR 20 release limits 'and actual. Maine Yankee plant-releases.
Based upon the analysis presented in the enclosed application-(Attachment 1),
Maine Yankee requests permission to dispose,:on a single time basis, the current inventory of decontamination solutions stored in approximately 200; fifty-five gallon drums. As stated in the application, the activity concentration and total activity is so limited that no individual, either worker or member of the public,!_
will receive a dose that approaches one millirem.
This maximum hypothetical dose ~
which is about -100 times less than natural background radiation,. would be indistinguishable from normal variations in background radiation: levels.. It ~is also well within the Maine Yankee site dose objectives as: expressed in the plant's' Technical Specifications, as well. as all current NRC release limits,;and negligible when compared to the dose the public receives from background i
radiation.
r Very truly yours, OAb h
