$UBJECT:
RANCHO SECO EFFLUENTS RELEASE AMENDMENTS
1
Attached is Amendment No. 98 and the NRC Staff's safety Evaluation Report
(SER)forRanchoSeco,issuedMarch 17 .1988. The amendment revises the
j
i
technical specifications to resolve pro,blems identified in Inspection
Report 86-15.
i
Of special interest is the staff's conclusion in the $ER
that ' deficient technical specifications were responsible, in part, for
the offsite contamination prchlam.' Amendment No. 98 also demonstrates
-
the extensiveness of the corrective actions required.
We recommend that you provide to the Department of Justice either a cop of
the Amendment and the $ER, highlighting the quoted language, or prefera ly
a copy of this memorandum with the attachments.

REASON FOR CALL:
To obt.Jn clarification on NRC impressions on the use of the
LLD equations in Tech. Spec. Table 4.21-1.
,
,
.
RESOLUTION REACHED: Mr. Yuhas' impression was each RHUT and Retention Basin release
_
should be counted to the "apriori" established count time
using the Tech. Spec. LLD equation.
He also suolested that
the Ranch establish a position on any questions
- hey have
concerning implementation of #nendment 98 and send the letter
to Charlie Willis with a copy to Region V.
The letter should
state if the HDC concept should be used and what the Ranch should
,
!
do.(or will do) if an isotope is less than HDC but greater than LLD.

Criteria For Environmental Lieuid Releases:
Retention Basins Nort h r South will be sarpled

-
prior to release at an LLD sensitivity stated in
Item 1 above.
3.
criteria For Seecial case Lieuid Accumulations:
When samples are required for standing water,
spills, etc., in areas that are contaminated or
potentially contaminated (e.g., blocked off stora
drains in " tank fara", solidification pad, spills
and/or drainage from water sources inside
" controlled access areas", etc.), they shall be
counted to meet a minimum sensitivity of LLD
levels if they are to be released directly off-
site.
If these liquids are to be pumped to RHUT
(A/B), they do not have to be analyzed prior-to
pumping to RHUT (A/B).
