ABSTRACT l
l This is a report of the progress made during the first part of a proposed nulti-year program of geologic and hyarologic investigations at the Western New York Nuclear Service Center. The New York State Geological Survey previously worked (1975-1979) on a snall part of this area, specifically that of the New York State-licensed radioactive waste burial trenchec. During the latent reporting period a large scale topographic map of the 140 hectare site immediately surrounding the nuclear fuel reprocessing plant has been produced, and three additional permanent stream stations have been installed to allow monitoring of nost runoff from the site.
Ten holes drilled in the North Plateau determined the geometry of the surficial gravel deposits there. A synten of ground-water monitoring wells was established in these holes. The second phase of the geonorphic investigat-ions of the Buttermilk Creek drainage basin and a study of the effect of submergence on the geotechnical properties of the burial till were completed.

1.0 INTRODUCTION
The Western New York Nuclear Service Center (WNYNSC) is located in West Valley, Cattaraugus County, 48 km south-east of Buffalo, New York. Centrally located within this 1354 hectare property.is a nuclear fuel reprocessing plant which stopped operations during 1975. Immediately to the north of the plant are two underground storage tanks filled with liquid radioactive waste. South of the plant is a burial area for highly radioactive solid waste licensed by the United States' Nuclear Regulatory Commission (USNRC).
2 A commercial, New York State-licensed, burial ground for waste with low radioactivity is also located on the southern area of the site. The locations of these areas are illus-trated in Figure L a map of the approximately 140 hectare secure area within the WNYNSC property.
- The New York State Geeological Survey (NYSGF) had.been the lead agency in an interdisciplinary research program in-cluding geologic, geomorphic, surface and groundwater in-vestigations since 1975. These investigations have_ involved the cooperation of many agencies in both the state and federal governments. These agencies have included the New York State Department of Health, New York State Department of Environmental Conservation (ENCON), New York State Energy Research and Development Authority (NYSERDA), and the United States Geological Survey (USGS). Studies of the Western New York Nuclear Service Center were initially funded by 2 the United States Environmental Protection Agency (USEPA),
then jointly by the USEPA and the United States Nuclear Regulatory Commission (USNRC), and then solely by the USNRC.
1 These earlier studies focused on the New York State-licensed burial trenches and any potential pathways of radionuclide migration from this area. A list of reports that resulted from these NYSGS studies can be found in Appendix A.
This report deals with the first part of a proposed multi-year program designed to understand the geologic character-istics and processes of this part of New York State. The program goals are to evaluate the adequacy of the burial sites at West Valley for their containment of radioactive wastes, and to establish their expected natural life span.
Expanding on former studies, this research will define the geologic and hydrologic characteristic of the WNYNSC site including the South Plateau, the area including the NYS
' burial area and the NRC burial area _and the entire North Plateau,and surrounding area. The presently funded part i of this project has collected data for the evaluation of the geologic and hydrologic properties of the entire site.

t 2.0 PURPOSE OF STUDY During August 1979, the NYFGS began the first part of a USNRC-funded study of 1354 hectare of the Western New York Nuclear Service Center. The goal of this study is to learn enough about the natural processes at work to evaluate the adequacy of the prescat containment capabilities and the probable life span of the radioactive waste burial sites at West Valley. This study will define the surface and sub-surface geologic and hydrologic characteristics of these sites and the surrounding areas to determine the potential for radionuclide migration off site.
This broader study is a logical extension of the studies done by the NYSGS which focused on khe New York State-licensed burial trenches.
As in the past, the NYSGS is cooperating with the USGS, which is investigating site hydrology and handling the logistics of the drilling programs, and the Radiological Sciences Laboratory of the New York State Department of IIcalth (RSL) which is providing the radiochemical analyses of water and sediment samples.
The integration of the information generated by each of these studies forms the basis of this first phase of the site-wide investigation. As this investigation continues an ,
overview of the North Plateau area which contains the under- l ground high-level radioactive liquid waste storage tanks '
and the NRC burial area will emerge. This will result, when combined with earlier studies, in a complete geologic and hydrologic characterization of the area occupied by the Western New York Nuclear Service Center.

4.0 CONCLUSION
S This initial ~ phase of geologic and hydrologic investigations of the 1354 hectare area occupied by:the WNYSC has estab-lished a framework upon which final recommendations may be based. This framework will also be used to support a cohe-sive interpretation of the data collected. During this in-itial investigation, five tasks have been accomplished in the construction of this framework.
4.1 A large scale (1:100), detailed (contour interval of two feet) , topographic map of the 140 hectare secure area has been produced for use as the base map for the investi-gation.
4.2 Three new stream monitoring stations have been emplaced in a cooperative effort with the USGS. These stations:
4.2.1 expand the pre-existing network to allow monitoring of runoff from most of the total area occupied by ,
the site -
l 4.2.2 are equipped with improved automatic sampling equipment to capture runoff more effectively, including storm events ,'
4.2.3 were positioned using new siting techniques and obtain winter samples by maintaining a section of ice-free channel under each station.
4.3 A site-wide 'drilli.ng program has been completed. This cooperative program wi,th the USGS consisted ~'
of the drilling i of ten new wells to: /,
1.3.1 -establi'sh the geom'e'try of the surficial gravel deposit on the North Plateau' area of the site
- 4.312 install a ground water monitoring system for the North Plateau area .
4.3.3 provide additional stratigraphic information on a' site-wide basis
.A. 3.4 obE11'n samples of soil and grou'ndwater for radio- -
nuclide analyses.

s 4.4.1 there is significant clast movement in re-sponse to annual flood events in the Butter-milk Creek 4.4.2 down-slope movement of the valley wall material is a continuous process of generally small contribution to overall derudation of the area 4.4.3 suspended sedinent discharge contributes two-thirds of the estimated yearly erosional volume 4.4.4 the overall denudation rate can be estimated /
at 6600 cubic meters annually.
4.5 After two years of submergence in a research trench, a geotechnical analysis was made of selected soil samples.
This testing was to estimate any alteration of engineering properties of the burial till as a result of the flooded condition. It was found, and reported in Hoffman and others (1980), that:
4.5.1 there was some increase in soil moisture content 4.5.2 when compared with equivalent soil samples from an earlier study (Fickies et al. 1979) the unit weight of the soil had decrsasE'd 4.5.3 the prediction of these alterations, based on the fresh samples in the earlier study, was confirmed.

l 5.0 RECOMMENDATIONS FOR FUTURE PROGRAMS OF THIS STUDY l 5.1 The drilling of several deep wells, as previously proposed by the NYSGS and USGS, is to provide information on the litnology and the deep geohydrologic regime. Tenta-tive locations for these deep wells have been established (Appendix B).
5.2 Continuation of the geomorphic studies or the Butter-milk Creek drainage basin (after Boothroyd et 41., 1979, 1981) to:
5.2.1 measure the spring freshet water and sediment discharges 5.2.2 obtain ages for Buttermilk Creek terrace levels 5.2.3 continue to monitor clast movement in Butter-milk Creek and initiate similar studies in Frank's Creek 5.2.4 study the Buttermilk Creek's delta in Cattarau-gus Creek 5.2.5 construct longitudinal profiles of Quarry Creek and the West Branch of Frank's Creek.
5.3 A study of the sediment in the area behind the Spring-ville Dam, which is downstream of the site, to determine its volume and the rate of sedimentation.
5.4 A wide area landslide study to estimate rates of general downslope movement. This study would involve the measurement of hillslope angles, determination of the lithology of the sliding units, characterization of tree growth forms, and surveys to measure the sf.ze and shape of previous slides.
5.5 Sedimentological and petrological studies to establish a classification scheme, based on lithologic characteristics, of the geologic units found on site and in the general area.
5.6 The construction of a Holocene map to identify currently operating geological processes to compare with the glacial geology maps of the area.
5.7 Installation of additional surface water monitoring stations on the Thomas Corners Road Bridge and the Frank's Creek railroad bridge to measure water and sediment discharges from these drainage basins.
7
5.8 Investigation of the acquisition of improved automatic stream monitoring equipment as the harsh weather and remote location of the stream stations make low maintenance, high reliability equipment necessary. ;
5.9 A study of the erosional history of the Cattaraugus Creek as a basis of predictions of local changes in base level.
5.10 The placement of additional rain gages to include the entire drainage basin in the area being monitored.
5.11 A geophysical survey using resistivity and seismic techniques to augment the present subsurface data for stra-tigraphic interpretation and to delineate landslide units.
5.12 An analysis of sediment samples for pollen to use for age determination and climatic conditions interpretation.

A 6.0 GEOLOGIC SETTING 6.1 Paleozoic Geology The Western New York Nuclear Service Center lies in the glaciated Allegheny section of the Appalachian Plateau physiographic province. The regional bedrock is Late De-vonian and older with the site immediately underlain by shales and sandstones of the Canadaway and Conneaut Groups (Rickard and Fisher, 1970). The bedrock is relatively un-deformed and forms a shallow, southern-dipping monocline.
Bedrock exposures are sparse and limited to discontinuous ledges at higher elevations or gorges cut by Pleistocene and Holocene fluvial systems, There are no major folds or faults recognized in the site bedrock. Historically, the area has evidenced minor seismic activity. Dames and Moore (1970) believe that the strongest ground motion that would be experienced at the site would not exceed Intensity IV. The only significant structural feature in the site vicinity (37 km to the east) is the isolated, north-south trending Clarendon-Linden Structure (Chadwich, 1920; VanTyne, 1975; Fakundiny et al., 1978).
The preglacial topography was an upland dissected by deeply incised valleys. Valley entrenchment occurred during epi-sodic periods of regional uplift. This uplift caused a reversal in drainage direction from the initial southward to present, northwest drainage system (Calkin and Muller, 1980). The valleys were subsequently infilled with a maxi- '
mum of 180 m of Pleistocene and Holocene sediments. Depth to bedrock in the vicinity of the site varies from several meters to 150m (Nuclear Fuel Services, 1962; Calkin et al.,
1974; Randall, 1980).
6.2 Pleistocene Geology Marginal oscillations of the Pleistocene continental ice sheet produced sequences of different kinds of glacial de-posits which veneer the preglacial surface. Detailed de-scriptions and interpretation of the glacial deposits in the site vicinity are discussed in Muller, 1977; Dana et al.,
1979; LaFleur, 1979, 1980. Types of deposits described are interbedded lodgement, ablation, and morainal till, pro-glacial lacustrine, and outwash.
9
Illinoian-age glacial deposits are poorly exposed but several lines of evidence indicate an extensive pre-Wisconsinan glaciation history (MacClintock and Apfel, 1944; Calkin et al., 1974; Muller, 1975).
Muller (1975) identified four Wisconsinan glacial advances based on deposits in Cattaraugus County. From oldest to youngest, the deposits include the Olean, Kent, Defiance, and Valley Head Moraines. The Olean is correlated with the middle Wisconsinan (Altonian) Titusville glaciation in Pennsylvania (Muller, 1977). The subsequent galciations are late Wisconsinan (Woodfordian) in age. Olean and Kent ice covered the entire land surface whereas the Defiance and Valley Heads ice occupied only lower elevations within valley walls.
The Western New York Nuclear Service facilities lie on and in deposits of the Lavery till complex of the Defiance glaciation. The deposit comprises a clayey, silt till with minor amounts of deformed lacustrine clay and silt. LaFleur (1979) recognizes three interbedded subfacies within the Lavery till. Comprehensive descriptions of the Lavery till are given in Whitney, 1977; Larleur, 1979, 1980a, b; Fickies et al., 1979; Fakundiny et al., 1980; Hoffman et al., 1980.
6.3 Holocene Geology Development of the Holocene landscape has been controlled by fluvial and mass wasting processes (Boothroyd et al.,
1979, 1981).
Drainage from upland areas, after deglaciation, deposited sand and gravel alluvial fans on the older glacial deposits.
One of these fan deposits form the surface of the North Plateau area of the WNYNSC facility (Figure 2). A series of small fans are also developed along the low terraces of the Buttermilk Creek.
The drainage pattern of Buttermilk Creek and its tributaries, was developed during the late-glacial meltwater drainage with its initial incision occuring prior to 9920 240 BP (Boothroyd et al., 1979). Fluvial sedimentation is accomp-lished by b'e3 ~a'nd suspended-load transport with the highest rates related to flood events. A series of fluvial terraces have been created as the Buttermilk downcut and widened its valley by lateral migration of the channel. Mass wasting in the Lavery deposits exposed along valley walls is wide-spread (LaFleur, 1979; Boothroyd et al., 1979, 1981). Soil creep, earth flow, and slump blodk sITding enhance widening of the stream valleys.

7.0 GEOLOGIC INVESTIGATIONS 7-.1 Topographic Mapping A base map suitable for detailed geologic work for the entire WNYNSC site was obtained on contract from Erdman Anthony Associates of Rochester, New York. This is a topographic map at a scale of 1:100 with a two-foot con-tour interval compiled from aerial photography flown during May 1980 (Figure 3). The boundaries of the NYS and NRC burial areas were surveyed in January 1981. This topo-graphic map of the approximately 140 hectare security area surrounding the nuclear fuel reprocessing plant has proven detailed enough to serve as a base map for the project. The aerial photographs have also been enlarged to the man's scale for use in the field to plot locations with maximum accruacy. All wells for which we have subsurface data have been plotted on this topographic map.
7.2 Stratigraphic Interpretations The locations of wells have been plotted on the base topo-graphic map, preliminary cross sections of the geology are being compiled, Although this work is still incomplete, our understanding of the subsurface is increasing with the production of each section. These geologic sections (Figure 4 and 5) are keyed to the map, illustrated in Fugure 6 to allow a general three dimensional stratigraphy of this area to be visualized.
The detail of these cross sections is enhanced by the drilling of ten new holes during the fall of 1980 as part of our cooperative program with the USGS. A summarey of the wells drilled as part of this program is described in Table 1.
The locations of these wells were chosen by the USGS and NYSGS in cooperation with Nuclear Fuel Services (NFS) per-sonnel, the site operator, to assure the satisfaction of all parties, each with a different interest, in the drilling program. The final well locations are shown on Figure 7 as are the three surface sampling locations.
The major purpose of the drilling was to establish the geometry of the North Plateau surficial gravel and to in-stall a groundwater monitoring system and thus define the groundwater movement and i'intify possible radionuclide migration through the uppe. 'ayers of sediment of the North Plateau. The North Platear area (Figure l) differs geologi-12

cally from the NYS- and NRC-licensed burial areas in that the uppermost unit is layered gravel that forms a Quater-nary alluvial fan (Figure 2). This deposit is approximately 40 feet thick and tapers toward the south. The fan material is much more coarse-grained than the till which underlies it and is relatively permeable which makes it a conduit for ground water. The data from seven of the wells determined the thickness of the surficial gravel deposit of the North Plateau and the remaining three amplified the stratigraphy west of the burial areas. The geologic and. hydrologic properties of this deposit, and those of similar composi-tion nearby will be studied further during the 1981 field season.
A six-inch, O.D., 3,25 I.D. hollow stem Power-Flight auger was used by the USGS to drill these' wells. A two-inch i O.D. split spoon sampler was driven two feet ahead of the
, auger to retrieve a continuous sample core. Two-inch di-l ameter PVC well points were installed at all locations
! except three, where groundwater level recorders were in-stalled.
i' Well 80-10 was sealed with concrete in October 1980. Con-tinuous water level recorders were installed during Janu-ary 1980 in wells 80-2, 80-3, and 80-4. The water levels in the six remaining wells will be recorded manually by USGS personnel.
The sediment samples were examined and described in the field by both NYSGS and USGS personnel. The NYSGS logs are included in Appendix C. Following logging, each sample was wrapped in paraffin and prepared for transport to the RSL for radiochemical analysis. Pumping tests yielded samples of groundwater which also were analyzed for radionuclides. The radiochemical analysis of the-sedi-ment samples are listed in Table 2 and the ground water radiochemistry in Table 3.

8.0 GEOMORPHIC INVESTIGATIONS The second phase of the geomorphic and erosion study of i
the Buttermilk Creek drainage basin (Figure 8) was completed l and reported in detail by Boothroyd and others (1981). This study was a continuation of the investigations initiated in 1978 and reported in Boothroyd and others (1979). The objectives of Phase II were determination of the seasonal, annual, and long term modification of Buttermilk Creek and its tributaries adjacent to the Western New York Nuclear Service Center in order to estimate a denudation rate for the Buttermilk Creek drainage basin. Remeasurement of parameters investigated in Phase I (Boothroyd et al., 1979) indicates geomorphic changes in Buttermilk Creek are related l to bedload transport by the migration of transverse bars.
I Clast movement is significant (3 - 6 meters per year) in response to one-year flood events. Extreme events, such as hurricanes, result in up to 60 m of bar slip-face migra-tion. Suspended sediment discharge during a typical yearly flood event is equivalent to the erosion of an in-place till volume of 3000 cubic meters. This is two-thirds of the esti-mated yearly erosion in the Buttermilk valley. Downslope slumping and earthflow of the valley wall material is thought to be a continuous process (1.5 cubic meters per year). Volumetrically, little sediment is contributed to the Buttermilk system by this process except when large masses are emplaced by block gliding.
Based on measurements of bed- and suspended-load transport and the volume of sediment deposited in the Nuclear Fuel Services water supply reservoirs, a preliminary estimate of the overall denudation rate for the Buttermilk Creek valley is 6600 cubic meters per year. The longitudinal profiles of the east and west branches of Frank's Creek indicate these tributaries are unstable and the valleys will continue to rapidly downcut and widen. Tributary ero-sion is independent of base-level changes in Buttermilk Creek.
A third phase of geomorphic investigation will be revision of dhe bar-complex map (Boothroyd et al., 1981) and measure-ment of clast movement at established stations to improve the data on gravel movement in the Buttermilk Creek. The terraces at several levels, identified by the previous studies, will be searched for material so that an age may be obtained in order to establish a more accurate erosional history of this drainage basin. Because floods are a major factor in the denudation of the area, a spring freshet will be monitored for water and suspended sediment discharge as 23

l well as large clast movement. General mass-wasting including soil creep, slumping, earth flow, and block gliding processes will be investigated by measuring movement at, and studying the growth forms of selected trees. The identification of the geomorphic characteristics of the landslides will be generalized in an effort to identify potential instabilities.

9.0 GEOTECHNICAL INVESTIGATIONS As part of the geologic investigation of the Western New York Nuclear Service Center site, the second part of the geotechnical analysis of soil samples was completed to evaluate the containment capability of the sediments of the NYS burial ground. Research Trench III, dug for the earlier investigation of the engineering properties of the site (Fickies et al., 1979), was left open and allowed to fill with water fr6m rain and snow melt (Figure 9). This submersion of the sediment for almost two years was to recreate the conditions encountered by the flooding of the trenches in the NYS burial trench area. The research trench allowed direct measurement of the behavior and relative stability of the burial medium under these flooded conditions. The soil samples analyzed showed some increase in moisture content and a decrease in unit weight, indicating a slight swelling. Changes in plasticity were insignificant.
The methods and results of this investigation are presented in full in Hoffman and others (1980) and confirm the predic-tions of engineering properties made during the first part of the geotechnical investigation (Fickies, et al., 1979).

10.0 SURFACE WATER INVESTIGATION The expansion of the investigation to include the entire Western New York Nuclear Service Center site required that a more comprehensive surface water monitoring and sampling project be designed. The goal of the water studies is to describe the overall water balance more accurately and to provide a method of predicting possible radionuclide migra-tion.
As in previous projects the surface water program was de-signed and is being conducted jointly by the NYSGS, the USGS, and the RSL. The USGS is responsible for the purchase, installation and maintanence of the monitoring equipment and interprets the geohydrologic records. The RSL, under sub-contract with NYSGS, analyses the water and sediment samples taken at the stream stations and provides interpretations of the radiochemical results. The NYSGS has the responsibility for the develcoment of the sampling procedure and the inter-pretation of the resultant surface water data, i Runoff from the site is measured by a network of stream monitoring stations. The initial stream monitoring stations were installed as part of the early USEPA-funded NYSGS re-search at the WNYNSC during December of 1975. The Lagoon Road and Swamp stations, previously referred to as Station Numbers Two and Four respectively, monitor the drainage from approximately half of the NYS burial trench area. The drainage for the Lagoon Road station includes a large part of the NRC burial area as well. The Frank's Creek Station, Station Nymber One, collects runoff from the largest area of the three including the remainder of the NYS burial and Southern Plateau areas. The drainage basins of each of these stream stations is shown in Figure 10.
To augment this existing network and expand the monitoring effort to the North Plateau, three new stream stations were designed and installed, with the assistance of the USGS, during the Fall of 1980. Two of the new stations, NPl and NP3, are located on small streams draining the North Plateau area. The third permanent stream monitoring station, Burial 1, recieves drainage from the NRC burial area and part of the NYS burial trenches. The drainage basins of each of these new stations is illustrated in Figure 11.
The expanded network of stream monitoring stations now has the capability of measuring discharge, stage, and taking samples automatically for radionuclide and sediment concen-tration analysis for most of the water leaving the secure I

area of the WNYSC site. To aid in the definition of the
' water balance of the West Valley site, raingages have been maintained and a snow survey is planned to measure the to-i tal precipitation. The rainfall measured during the 1980 season is listed in Tables 4 and 5. The locations of the raingages and the stream stations are illustrated in Figure 12.
Water samples collected at the Frank's Creek, Lagoon Road, and Swamp stations have been analyzed by RSL for Gross Alpha, Gross Beta, HTO, and suspended sediment concentration. These measurements are listed in Appendixes D and E. Background
' radionuclide concentration analyses of water samples taken i
from Buttermilk Creek on May 28, 1980 are included in Table 6.
The.new stream monitoring stations were designed and em-placed in an attempt to alleviate some problems that had occurred with the older stations. These older stations have never collected winter and early spring flow informa-tion because of ice and snow blockage of the monitoring channel. The new station, developed by the USGS (Figure 13) was designed to keep a section of channel open throughout i the year to permit data collection. Each station is built on a steel I-beam frame assembled offsite. After the sites e
had been chosen and station installation procedures began, it was discovered that one of the original locations was 1 unsuitable because of large-scale landsliding. The insta-bility of the valley walls required footings to be dug be-fore the station bases could be installed. As the result of this delay, the helicopter lift of the station platforms did not occur until July 23, 1980. The installation of the instrumentation, various electronic and hydraulic devices, and heating equipment did not occur until August 22, 1980, because the remote location of the station sites severely limited access; only an All-Terrain Vehicle could be used i to transport equipment.
The instruments installed in the stream monitoring stations to measure stream discharge and stage include an automatic sampler to take either flow- or time-dependent water samples for radionuclide and suspended sediment analysis. A Manning F 3000A flowmeter, a Stevens Type A Model 71 stage recorder and a Manning OM-1 Overflow Monitoring Sampler were provided by the USGS to collect these data. The flow meter is the basis of this system because its electronic water sensor.
also activates the stage recorder and operates the flow pro-portioned sampler. This integrated system was supposed to collect water samples, stage and discharge measurements on 31

SUMMARY
The NYSGS study of the entire WNYNSC site is an outgrowth and expansion of the interdisciplinary research project which included geologic, geomorphic, geotechnical, and hy-drologic investigations of the NYS-licensed burial trench area between 1975 and 1980. This is the first progress re-port of the expanded program, which has a proposed schedule of several years duration. For background, a general his-tory, including Paleozoic, Pleistocene, and Holocene events, is included in this report.
A topographic map of the area occupied by the nuclear fuel reprocessing plant and the burial areas for radioactive waste has been produced on a large enough scale (1:100) to serve as a base map for these investigations. Ten wells were drilled in the North Plateau to install a groundwater monitoring system and to define the geometry of the surficial gravel deposit found in this area. Preliminary stratigraphy, presented in the north-south and east-west geologic cross sections, resulted from this drilling project.
The geomorphic study of the Buttermilk Creek Drainage basin, continued from previous NYSGS investigation, recently com-pelted its second phase. This includes estimates of an over-all denudation rate through the measurement of bed-load move-ment, suspended sediment discharge, and the rate of mass wasting in the creek valley walls.
The sediments within a research trench, dug for an earlier investigation and permitted to stand full of water for two years, were reexamined to determine what changes in their geotechnical properties long term submergence produced. No major variations in the characteristics of the burial till occurred.
The surface water program, originally designed to monitor the runoff from only the NYS burial area, was expanded to include the North Plateau with the addition of new perma-nent stream stations. The new stations have the potential capability of measuring discharge, stage and taking samples automatically on a flow proportional basis to allow for more complete monitoring of the radionuclide and suspended sediment concentrations in the runoff from the site. To date, these stations have not operated to their full poten-tial.
The interpretation of the data collected during this part of the study has allowed for the delineation of new areas 42

l i
l that need investigation to complete this research project.
These areas include deep drilling to obtain information on the composition of strata underlying the entire area, the l continuation of the geomorphic study of Buttermilk Creek's drainage basin, sedimentology and petrology of the princi-pal glacial strata, a study of the erosional history of the Cattaraugus Creek, and additional surface water monitoring capabilities to more accurately measure the effect of storm events. This combination of new projects and the expansion of existing ones will result in a more thorough knowledge of the geologic and hydrologic characteristics and processes occurring at the WNYNSC site.

APPENDIX B PROPOSED DEEP DRILLING PROGRAM 54
l l
Deep Drilling Program As part of the cooperative research program, the New York State Geological Survey and the United States Geological :
Survey have proposed to drill five deep holes at the Western New York Nuclear Services Center. These holes will be cored and the. core samples fully described to establish the stra-l tigraphy of the entire thickness of glacial deposits in the pre-glacial Buttermilk Creek Valley. The extentof hydraulic l
conductivity and distribution of head of the groundwater in these deeper. glacial deposits will also be measured. Tent-ative locations for these deep holes are illustrated in Figure 14. The final locations of all holes will be mutually agreed upon between the surveys and approved by the New York State Department of Environmental Conservation, site regu-lator, the New York State Energy Research and Development Authority, site owner, the operator of the site and the U. S.
Nuclear Regulatory Commission.

This is a report of the progress made during the first part of a proposed multi-year program of geologic and hydrologic investigations at the Western New York Nuclear Service Center. The New York State Geological Survey previously worked (1975-1979) on a small part of this area, specifically that of the New York State-licensed radioactive waste burial trenches. During the latest reporting period a large scale topographic map of the 140 hectare site immediately surrounding the nuclear fuel reprocessing plant has been produced, and three additional permanent stream stations have been installed to allow monitoring of most runoff from the site. Ten holes drilled in the North Plateau determined the geometry of the surficial gravel deposits there. A system of ground-water monitoring wells was established in these holes. The second phase of the geomorphic investigations of the Buttermilk Creek drainage basin and a study of the effect of sutnergence on the geotechnical properties of the burial till were completed. .
