RADIATION PROTECTION SECTION
Dear Gerry:
Regarding Mr, Millard*s letter of February 21, 1980, in par-
ticular the comments on release of the Rio Puerco, there ap-
parently is either a divergent set of data or a difference in
semantics with respect to Lead-210 total concentrations. We
hat, since August 30, 1979, none of our samples showed
cor.cer.tra lions in excess of 75 percent of the allowable level
'.5 -C.I.; .e interested in receiving any datci you have which
i '-,.-*:-.„' .'. i .-T -"- r co fi c c n'- r JI L i o n s.
+- >1 :S f-
Pre-3^i_l £-:.reaJn quality data collected by several gcve-r".nent
a9e^.L'ie5 ar.d UNC Mining & Milling was severely limited in terms
of total constituent levels, thereby making comparisons with
current concentrations difficult. However, over a period of
three C3) years prior to the spill Kerr-McGee did sample and per-
form total Radium-226 analyses The data sheets (attached) are
summarized below:
Number

Mean(pCi/1)
39-541.128,6
This information should be reviewed and utilized as representative
background data in a manner jointly acceptable to UNC Mining &
Hilling and the NMEID.
I would suggest that a two (2) sigrna warning level, used in Radio-
chemical Quality Control Programs/ be established as the boundary
for expected variations in background. For station RWS-27, where
o\ir current weekly samples for total constituents are taken, this
calculates to 2S.6 ±38.72 pCi/1 or an upper warning limit of
67.32 pCi/1. A further extension of this concept would allow
le'.-":-3 ^ f -r ^o 97 .32 pCi/1 under Part 4, Appendix A / of the New
:';e:-:i-;3 =r.i:^5.rds rur releases to an unrestricted ared.
We thsr. c'^n eliminate concern over seemingly high concentrations
and more accurately compare them to the standard. This may be
done by utilizing recent RWS-27 data and the equation from Appendix
A, below:

(1) Concentrations of Radium shown as zero were less than 67.32 pCi/1
* Acceptable levels are shown to exist.
Thi^ type of approach is supportable and should be explored further
for determining mutually acceptable background concentrations.
With regard to costs associated with cleanup of the Rio Puerco
sediments, we have calculated the values requested in our meeting
of March 25, 1980- For the first five (5 ) miles downstream of the
da.^ a total of $250,654 was spent to remove 2,733 tons of stream
sedi^.enr. 5y comparing the mean values from each station for the
first arc third samplings we see a mean overall reduction of 11.6
:-'.is ^or.verts to a cost of $21^005 .10 pe\- picoCurie of
re^-.-i--^^;.-. .-,"/er the entire 5.1i mil^ strcL^;. or $4 ,223 .59 per
picc-C'-..-L^ of reduction over 1 mile. These figures should help in
your assessment of the reasonableness of continued cleanup. If
any further cost comparisons would be helpful, please let me
know.
Your thoughts on dealing with the matters discussed above will be
anticipated,
Regards,
Todd Miller,Manager of Environmental Operations
