Dear ltr. Stello:
We are in receipt of a license amendment request dated August 9,1977 from the fior:hern States Pcwer C:gany that would modify the tnticello (%:get 50-253 License DPR-22) P.adiation Environmental ltonitoring Program by removing C.;m s.mpiir.g and analysis.
I would agree that Mississippi River conditions in the vicinity of the Monti-cello plant are not conducive to efficient clam sampling. However, I would sugge.st that the Northern States Power clam sampling te:hniques and their vigor in discovery of clam beds might also contribute to the lack of success in clam satoling.
Since clans are an efficient water filter, I would prefer that clats not be drocped f. n the monitoring program until all alternatives that might imorove clan sar: ling efficacy have been explored. A few methods to improve efficacy c: e immedi:tely to mind: sampling during times when the clam population is cotimally largest, search and discovery of the best clam beds, utilization of submerged clam traps, implantation and containment in suitable trap-like containers of clams at cesirable locations relative to the plant outfall and intake.
I am sure these s"ggestions do not exhaust all possibilities.
'Would you let me knu whether -he Nuclear heculatory Ccmmission intenos to investigate clam sampling alternatives or other means by which clam monitoring can be improved.
Sincerely, 6'
