SUBJECT:
REVIEW 0F REQUEST FOR SUPPLEMENTAL STANDARDS FOR VICINITY PROPERTIES CAN-501 AND CAN-438 By submittal dated March 19, 1987, the Department of Energy (DOE) requested application of supplemental standards at two open land vicinity properties identified as CAN-501 and CAN-438, and located, respectively, at 27 Latimer Avenue and 412 Chartiers Avenue, N. Strabane, Pennsylvania.
N. Strabane is the township in which Canonsburg, Pennsylvania, is located.
Briefly, remedial action was performed at the
?
lot adjacent to the paved street and DOE requests that supplemental standards be applied for the residual radioactive material (RRM) which is buried under the paved public street.
l r
Discussion Approximately 4.2 and 13 cubic yards of RRM underlie the paved street vicinity properties identified as CAN-501 and CAN-438, respectively.
The i
RRM is buried beneath 10 cubic yards of clean fill at CAN-501 and covers approximately 200 square yards, while at CAN-438, the RRM occupies about 40 square yards of surface area to a depth of 20 to 40 centimeters.
l Gamma ray exposure rates range from 16 to 18 microR/h and 10 to 19 micro R/h, respectively, for CAN-501 and CAN-438, while respective Ra-226 concentrations range from 2.6 to 49.5 pCi/g and 1 to 86 pCi/g.
In both cases, the landowner is in agreement with the proposed remedial action.. Although the costs associated with not applying supplemental standards at CAN-501 and CAN-438 are not exhorbitant ($1900 and $2325, i

C- - v WM-038/RFB/87/04/21/1 MAY 0 51987 respectively), the cost is high relative to the potential health benefits. Thus, DOE has determined that the application of supplemental standards in accordance with the NRC guidelines and 40 CFR 192.21(c) is justified.
In addition, 40 CFR 192.21(c) specifies RRM buried under paved public streets as one example where supplemental standards would prudently be applied. Also, land records will be annotated by the State to signify that RRM has been left in place.
Conclusion Based on my review of DOE's request for supplemental standards at CAN-501 and CAN-438, I conclude that their request is justified. Therefore, DOE should be notified, in writing, that we concur with the proposed remedial action for vicinity properties CAN-501 and CAN-438.
