Dear Mr. McGaughy:
SUBJEL7: REQUEST FOR AEDITIONAL INFORMATICN - GRAfrD GULF NUCLEAR STATION, UNITS 1 AND 2 As a result of our continuing Grand Gulf envircnmental review, we have developed the enclosed request for additional information. This request was t
developed as a result of infornation received in recent talerhone conversa-tions with members of your staff, indicating that the Ranney well system may not be %nctioning as previously expected and reported to us.
Included are questions from tne Environmental Engineering Branch and the Hydrologic and Geotechnical Engineering Branch.
We request that ycu a.end your Envircnmental Re:: ort to reflect your responses to the enclosed request by December 12., 1980.
If you cannot :neet this date,-
l please inform the Project Manager, Joseph A. Martore, of the date you can meet as soon as possible, so that we may consider the need to revise our J
review schedule.
Please contact us if you desire any clarification of the enclosed request.
Sincerely, j
oe.cnal r.: et W

O Request for Additional Information Environmental Review Grand Gulf Nuclear Plant Docket No. 50-416 371.07 The groundwater quality, as measured during testing of the Ranney wells, is apparently poorer than previously expected.
Induced infiltration of Mississippi River water has seemingly not been achieved, due to high groundwater levels in the floodplain alluvium.
Since grsundwater levels, quality, and use differ from tlose parameters originally reported, we require the following additional information in order to assess the effects and impacts of the Ranney well system:
a.
Provide the results of the pumping tests performed on each of the Ranney wells.
Information provided should include pumping rate, drawdowns and water levels in the pumped well and observation wells, and comparisons of water quality between the water withdrawn and the Mississippi River water.
b.
Provide analyses of the proportions and amounts of groundwater that will be withdrawn from the alluvial aquifer and the river under various conditions of groundwater levels and river levels.
For each condition, discuss the expected differer.ces in groundwater quality, as compared to the groundwater quality if induced infil-tration were achieved.
c.
Discuss the cause of the abnormal groundwater levels.
Provide rainfall j
records, analyses of groundwater levels.and movement, and other pertinent data which support your conclusions.
i
~o.
I 2-d.
Discuss the adverse or Seneficial effects of high groundwater levels on the Mississippi River, Hamilton Lake, Gin Lake, and othe' small nearby water bodies and streams.
e.
Identify the potential impact on plant facilities of the degraded water quality.
340.22 1.
Based on the current water quality of the service water makeup from (3.6,5.3) the radial collector wells update tables 3.6.3, 5.3.3 through 5.3.6, and sections 3.6.1, 3.6.2, 5.1.4.5.3, 5.3.2.2, 5.3.2.3, and 5.3.3.
340.23 2.
Provide a copy of the current NPDES permit for the Grand Gulf site.
Also provide a short narrative.of the current status of the NPDES renewal activities.
