Arizona Public Service Company P.O. BOX 53999 ~ PMOENIX, ARIZONA'85072-3999 WILLIAMF. CONWAY EXECUTIVEVICEPRESIDENT NUCLEAR 161-03556-MFC/JRP October 24, 1990 Arizona Radiation Regulatory Agency Attention: Mr..Norman V. Pratt 4814 South 4'0th Street Phoenix, Arizona 85040 Dear Mr. Pratt Subj ect: Palo Verde Nuclear Generating Station (PVNGS)

Units 1, 2, and 3 Permit Application File: 90-001-028.8 Arizona Public Service Company requests state approval for disposal of very low concentrations of radionuclides's described in the attached document.

This application proposes to leave in place approximately 450 cubic yards of slightly contaminated sludge from the PVNGS Unit 1 and 3 cooling towers which has been deposited in the Mater Reclamation Facility (WRF) landfill and covered with uncontaminated topsoil. The disposal site is located on Company owned land which is fenced and is only accessible from the Company controlled area which is routinely patrolled.

Since a determination that the cooling tower sludge was slightly contaminated, PVNGS has taken steps to ensure early detection of the waste stieams which might contribute to the potential contamination of cooling tower sludge. The potential radiological and environmental impacts of the proposed disposal have been analyzed and evaluated and are presented in this application. The cost benefit of onsite disposal versus shipment to a low level waste facility is also discussed. APS concludes, based on the information presented herewith, that the disposal of this material presents no significant impact or hazard to the public health and safety or to the environment.

Should you need further information for this evaluation, please contact J. R. Provasoli at (602) 340-4160.

Sincerely, MFC/JRP/pmm Attachment 901i050207 901024 PDR ADOCK 0500052S P PDC

4.5 ANNUAL DOSE'ASSESSMENT The dose assessment analysis for the occupational and member-of-the-public pathways was performed based on the radionuclide analysis of, over 190 core samples taken from the Water Reclamation Facility sludge landfill ". Two dose pathways were evaluated for the- occupational. worker: direct gamma exposure and inhalation of resuspended mater'ial. Three dose pathways were evaluated for a member of the public after operation of the facility has 3

ceased: direct gamma exposure, inhalation of resuspended material, and ingestion involving. consumption of groundwater and veg'etation -grown on the disposal area.

In evaluating the dose pathway scenarios., it was determined that the only significant dose was 'delivered by the direct gamma exposure pathway to an occupational worker. Direct gamma exposure to a member of the public after operation of the facility has ceased is insignificant because of the half-4 life of the radiological constituents involved and additional cover that will be present at that time. Inhal'ation exposures were not considered to be credible due to the minimum 3-inches of soil covering already in-place and the fact that additional cover

- will'e added over the operating lifetime of the facility. The ingestion pathway was also not considered to be credible'ue to the inability of'the Water Reclamation Facility 'sludge landfill to support vegetation growth. In addition potable water for drinking is not viable due to,the high total dissolved solids (TDS) content and depth- of the perched water table.

In considering the sludge inventory, the only significant radionuclides contributing to external doses are Mn-54, Cs-137, and Co-60. Concentration of other radionuclides were measured at or below detectable limits. The

'annual doses for these three radionuclides were calculated using the methodology in Appendix A and are included in Tables 4.5-1 and 4.5-2. The P

estimated total annual direct dose to an individual occupying the sludge disposal area 'for 2000 hours0.0231 days 0.556 hours 0.00331 weeks 7.61e-4 months per year .is 0.69 mrem. The source term was 46 e

based on area-weighted concentrations derived from 'Figuies 4.5-1, 4.5-2 and 4.5-3, and is somewhat more 'conservative than using. an average of all measured concentrations. Worst case doses were calculated using the peak concentration analyzed for each radionuclide and assuming these peak concentrations were uniformly distributed across the entire disposal area.-

The maximum, annual dose in,this scenario is '3.3 mrem and is included in'able 4.5-2.

Both the average annual andrthe peak annual doses are small when compared to the annual natural background external radiation of 58 mrem for Phoenix, Arizona~~~. In addition, it P should be noted that adjustments for

,.representative values 'of dilution and occupation time, and credit for r

additional planned soil covering would substantially decrease the calculated doses.'

APPENDIX A DOSE CALCULATIONS Assum tions and Tn ut'Parameters E

1. Based on 'nventories and ,dose conversion factors, the. significant, radionuclides in the sludge were determined to be Mn-54, Cs-137, and Co-60. A uniformly mixed slab-source was. assumed in the direct gamma dose calculations.

2. The energy (MeV), yield (8's/decay), and half life (years) data used in the dose calculations are given in. ICRP Publication 38+.

3. The mass a'ttenuation coefficient (cm /g) and mass absorption coefficient (cm/g) for concrete and tissue are given in LaMarsh, 1977~'~.

4. The sludge and soil densities (g/cm ) used in the calculation's are assumed to be 1.20 and 2.00, respectively '

5. The shielded dose c'alculation constants (A, a>, and uq) are derived from LaMarsh, 1977'.

6.. 'For a uniformly distributed interval slab source, assume flux 6 ra s cm - sec s 2 x attenuation coefficien't (p)

This is slightly conservative since the summa'tion term of equation 10.52 of LaMarsh, 1977~'~, is < 1. For the cases evaluated, this term was assumed as I

1.0.

1 5 ' SITE CHARACTERISTICS 5.1 Geo ra h and Demo ra h The PVNGS site is located in Maricopa Country in southwestern Arizona, 16 miles west of the City of Buckeye and 34 miles west of the. nearest boundary of the'ity of Phoenix. Figure 5.1-1 identifies the'eneral location of the plant site with respect to roads and highways, communities, and cities in the vicinity. The site area is flat with small scattered hills.

~

To the west and northwest of the site are the Palo Verde Hills, sharply rising to 2,172 feet above- mean sea level: To the south is Centennial'ash, an intermittent stream backed by gently rising uplands with scattered,"

isolated, steeply sloped hills and buttes. Buckeye Valley, bisected by the Gila Rive'r, lies to the east and southeast. To the north and northeast, the terrain is a relatively flat desert traversed by numerous intermittent streams that are typical of the region (refer to Figures 5.1-2, 5.1-3 and Figure 5.1-2 illustrates the plant site, including topographical features.

and the location and orientation of principal plant structures.

The total area of the plant property is approximately 4,050 acres. The

'plant property line coincides with the plant site boundary, Units 1, 2, N

and 3 and their supporting facil'ities 'are located in the northern half of th'e site. The si'te is bounded on the south by Elliot Road and on the west ~

by Wintersburg Road. No public'roads or railroads cross the site. Site elevations range from 890 feet above mean sea level at the southern boundary to 1,030 feet above mean sea level at the northern boundary.

Figure 5;1-5 defines the boundaries of the plant exclusion area. The exclusion area boundary coincides with the plant site boundary; except in the southern portion of the property. Minimum distances from each unit to "the site'oundary is provided in Table 5.1-1.

5.3 Po ulation Distribution Figure 5.3-1 illus"rates the 1978 estimated residential population located within a 10-mile radius of the plant site. Data are displayed at 1, 2, 3, 4, 5, and 10-mile distances from the center line of the Unit 2 containment building for 16 compass sectors.
P Figures 5..3-2 through 5.3-10 illustrate the estimated residential "population located within a 10 mile radius of the plant site for the years 1980 through 2030.
5.3.1 Low Po ulation Zone The PVNGS low population zone (LPZ) has been defined as a-6,400 meter (4 mile) radius area, based on the center line of the Unit 2 containment building. The LPZ has been conservatively selected on the basis of providing effective emergency planning for the residents in the LPZ, as well as limiting radiation doses to below 10 CFR 100 limits to those residents outside the LPZ under the most conservative assumptions for a design basis accident.

'C As indicated in Figures 5.3-2 through 5.3-10, the population density.
of the LPZ is low and is expected to remain as such throughout the plant life, thereby enabling effective emergency planning. Figure 5.3.1-1 illus'trates the LPZ in terms of topographic features and transportation for evacuation purposes. There are no schools, hospitals, prisons, .or parks -located within either the LPZ or a.5 mile radius.
5.3.2 Po ulation Densit Figures 5.3-3 through 5.3-5 show 'the estimated residential population located within a .50 mile radius of the site for the years of initial'nit operation, i.e.,'1982, 1984 and 1986. Within.a 30 mile radius of the site, the following residential population projections are estimated".
1982 32,187 persons 1984 33,701 persons-1986 35,415 persons 4
'I Table 5.3.2-1 lists the cumulative residential population density within, a 30 mile radius of the site by annulus for the three unit startup dates. As can be seen from Table 5.3,2-1, the PVNGS site falls well below the uniform population density standard of. 500 persons per square mile as expressed .in Regulatory Guide 1.70, Revision 3.
Figure 5.3-10 shows the estimated residential population located within a 50 mile radius of the site for the end of the decade of
,plant life end, i.e., 2030.
Within a 30 mile radius of the site, the 2030 residential population projection is estimated to be 106,914 persons.

5.4 SITE GEOLOGY 5.4:.1 Site and.Site Vicinit Ph sio ra h The site is located in one of the intermontane valleys of the Sonoran Desert region of the Basin and Range physiographic provinces. This valley, known as the Tonapah Desert, is broad and relatively flat-floored, with through-flowing, intermittent drainage graded to the Gila River, the regional trunk stream. The site lies between two major intermittent drainages, the Hassayampa River on the east and the Centennial Wash on the southwest. These two drainages are within 3 to 5 miles of the site and drain toward the northern bend of the Gila River near Arlington. The major surrounding mountain ranges are the Palo Verde Hills.to the west, the Belmont Mountains to the north, the White Tank Mountains and Buckeye Hills to the northeast and southeast, and the Gila Bend Mountains to the south. Like most mountain ranges in the Sonoran Desert, 'the flanks of the surrounding mountains consist of pediment and alluvial fan surfaces that grade gently to the basin floor. The basin floor slopes gently southward from about 1,500 feet above sea level at the edge of the Belmont Mountains to about 800 feet elevation along the course of the Gila River, southeast of the site. The site is nestled between outliers of the Palo Verde Hills on a flat surf'ace, at about 950 foot elevation. The nearest edge of the Palo Verde Hills i.s about 2 miles west. of the site; the outliers are low-relief, rounded knobs protruding through the alluvium north and south of the site. The Palo Verde Hills range in elevation from about 1,200 feet directly 78

C adjacent" to the site to more than 2,100 feet at their highest point about 5 miles northwest of the site. The basin floor is dissected by several small ephemeral streams which flow southward and are integrated with the Gila River, about 10 miles southeast of the site. The natural, intermittent flow.of water in th'e washes has now interrupted, by an agricultural irrigation system and by PVNGS 'een construction activities. The micro-relief system, leveled'n local areas by agriculture, consists of small rills and gullies that carry the normal*runoff into the washes.
~~5.4.2 Site Vicinit Strati ra h Figure 5.4.2-1 is a geologic map and simplified stratigraphic column ~ ~~~
~~of the area within a radius of 25 miles of the site (site vicinity).~~
~~Figure 5.4.2-2 shows'eologic cross-sections illustrating the sub-surface geologic 'relationships of. the site vicinity.~~
The geologic formations within the, site vicinity are typical of the Sonoran Desert subprovince and include highly deformed metamorphic and granitic rocks of Precambrian age and moderately defor'med volcanic and sedimentary units of Tertiary age in the mountains, and undeformed volcanics and sediments of Pliocene to Holocene age in 'the basins. The metamorphic and granitic rocks are termed basement and moderately deformed volcanic and sedimentary units are termed bedrock, and the undeformed volcanics and sediments are h
~~termed basin sediments.~~
~~The emplacement E~~
of Precambrian plutons on granitic and. gabbroic composition are 'generally associated with the culmination of the Mazatal Revolution, and resulted in the metamorphism of surrounding rock to schist and gneies. The metamorphic rocks aie the. oldest rocks in the site vicinity and are 'subdivided into three subgroups:
~~greenschist facies metamorphics, metadiorites, and gneissic, granitic and hornfelsic rocks.-~~

~~The greenschist metamorphic rocks make up, onl'y a small fraction of the rocks in the site vicinity. They crop out' miles west of C~~
Gillespie -Dam and on the east flank of Saddle Mountain. The metadiorites are rare intrusive bodies found only in conjunction with the greenschist metamorphics in the Gillespie Dam area. The A C e
gneissic rocks are. the predominant'metamorphic subgroup in the site vicinity and compose about'ne-third of the Belmont Mountains and all of the Vhite Tank Mountains. A large segment of the Gila Bend Mountains, 20 miles west "of Gillespie Dam, is compos'ed on gneiss.
Scattered outcrops, of gneiss are also exposed 2 miles south of Gille'spic Dam. The granitic rocks are represented by granite and quartz monyonite, including aplite and alaskite, outcrops in the eastern portions of the Belmont Mountains, Maricopa Mountains,'he entire Buckeye Hills, and in the Gila Bend Mountains. Although not exposed in the Palo Verde Hills, granitic basement rocks were encountered in exploratory borings beneath the site property.
Bedrock in the site vicinity consists almost entirely of Tertiary volcanic rocks and Tertiary volcanoclastic and sedimentary rocks unconformably overlying the Precambrian basement rocks. The age and composition of these rocks-are similar to those throughout the entire Basin and Range province, Tertiary sedimentary and volcanic rocks are exposed in the western portion of the Belmont Mountains and the south-central flanks of the Gila Bend Mountains.
Sedimentary rocks in the Gillespie Dam area consist 'of arkosic conglomerate, lahar deposits, tulfac'eous sandstone, and eros'sbedded sandstone. The Tertiary sedimentary members of the sequence are interbedded with the Miocene 'ndesite and basalt .flows, flow breccias, and pyroclastic rocks. The Gila Bend Mountains are primarily composed of andesite and basalt which range in age from 19 to 28 million years before present. In the Palo Verde Hills, basaltic andesite, diabase, and basalt, with minor amounts of interbedded tuff, are approximately 17 to 21 million years old.
83
i.
Basin filling deposits overlying the Tertiar'y .volcanic sedimentary bedrock sequence are talus, colluvium, alluvial fan, basin alluvium, lacustrine, and fanglomerate. Ages of alluvial fan deposits on the surrounding mountain flanks range from Terti.'ary to Holocene, based .
on potassium-'argon ages of overlying basalt flows.. Two series of alluvial fan, deposits, (QYfn and TVfn) are stratigraphically below the Arlington and Gillespie basalt flows and, therefore,'re late Pliocene in age (greater than 2 million years before present).
Massive, extensive clay deposits penetrated by numerous water wells in Phoenix and Gila Bend basins attain a thickness of more than 700 feet between Phoenix and Litchfield Park and 850 feet 'in the Gila Bend Basin. These clay deposits are usually continuous across individual basins but'here is no direct, evidence that they are continuous between adjoining basins.
Late Tertiary and early Quaternary basalt flows interbedded with and overlying the basin sediments are the youngest volcanic rock units in the site vicinity. Four extensive olivine-basalt flows overlie Gila River terrace deposits and alluvial fan deposits. Whole-rock, potassium-argon ages. of these flows are:
~~Gillespie: 1.3 to 4.2 million years (nine samples) average age 3.3 million years.~~
~~Arlington: 1.2 to 3.2 million years (six samples) average age 2.2 million years Sentinel: 1.71 + 0.25 million years (one sample)~~
~~Gila Bend: 2.5 to 6.5 million years (three samples) average age 4.5 million years 84 e~~
~~i 1~~
~~I I~~
The youngest volcanic flows appear to be similar to widely scattered geomorphically young vents and flows throughout the Sonoran Desert subprovince. These volcanics are generally shown'on published maps-as Quaternary basalts, but the age data given above shows them-to be earliest Quaternary and/or latest Tertiary in age.
P 5.4.3 Pro erties of. Subsurface Materials Soil properties presented herein were deriv'ed from investi'gations-conducted at five unit areas which included the location of two potential units (Units 4 and 5). ~
The'engineering proper'ties of subsurface soils were inyesti;gated by drilling, sampling, laboratory testing, and geophysical- testing techniques. A summary of the generalized stratigraphy and associated eng'ineering properties is presented in this section.
~~Profiles depicting the generalized stratification, of subsurface materials at. the units down to bedrock (approximately 300 feet) are~~
~~. shown on Figures 5.4:3-1 through 5.4.3;3. The actual detailed soil stratification of the upper 65 feet is shown in the detailed excavation mapping of each of the power block excavations. The~~
~~'disclosed by the mapping is consistent with that 'tratigraphy derived from borehole information.~~

. of fine sands, silts, and clays of low plasticity are also common within the .transition zone. Such soils, classified as SM-ML and SC-CL, are generally 'stiff to hard and exhibit localized calcareous, cementation. Layers of sands with low silt and clay content (typically less than 30% fines) "are also encounteied within the transition zone.. The sands within the intermediate zone are generally medium dense'to very dense'.
I The intermediate zone generally increases in thickness "and h
complexity of laye'ring from Unit 1 southward. At Unit 1, the transition b'etween the upper coarse-grained and lower fine-grained zones is very abrupt in most areas and the intermediate zone is discontinuous in 'those areas. At Units 2 and .3, the intermediate zone generally occurs within the interval of approximately 30 to 50 feet deep, immediately above the well-defined stratigraphic member E contact.
The lower zone deposits primarily consists of medium to highly plastic, hard clays. Sands and s'its comprise a very small portion of the formation. Layering within the deposits is uniform and relatively'flat. Several major layers are traceable across the site.
5 4.3.2 Static Soil Pro erties The results of the field and laboratory testing program were used to evaluate -the engineering properties of site .soils.
Typical static material properties foi site soils are presented in Figure 5.4.3.2-1. Grain size and plasticity characteristics of various soil" layers are presented in Figures 5.4.3.2-2,and 5.4.3.2-3. Results of standard penetration tests in granular soils beneath Units 1, 2, and 3 are presented in Figure 5.4.3.2-4. A summary, of shear strength 'est results. is presented in Figure 5.4.3.2-5 ~

5.4.3.1 La er Desc i tion To determine representative engineering properties, the subsuiface profile has been subdivided into three soil depth zones representing different dispositional environments and generally exhibiting different engineering characteristics.',
For discussion purposes, these zones are defined as the upper zone (0 to 30. feet), intermediate zone (30 to 55 feet), and lower zone (55 to 300 fe'et). These depth zones correspond approximately to the following geologi:c lithozoners and stratigraphic, members presented on the geologic profiles and maps of excavations:
Stratigraphic D'e th Zone feet Geolo ic Lithozone Members Upper (0 to 30) Upper LZ5 A and B Intermediate Lower LZ5 C,D, and Upper-(30 to 55) (Transition)
Lower (55 to 300). I.Z4 and LZ3 E,F,G,H,I,J & K I
The upper zone contains granular soils deposited in a high energy environment. Such deposits primarily consist of relatively well-graded silty and clayey sands with some fine gravel. Relatively uniform, fine, and medium sand layers are
. also present, to a lesser extent. With the exception of the upper 2 .or 3 feet which are generally loose, the deposit is gener'ally medium dense to dense. Zones of caliche cementation
.are common.
The intermediate zone represents a,gradational interface between the upper coarse-grained pluvia deposits and the underlying, fine-grained lacustrine deposits. It consists'f crudely
'I stratified clay, silt,, and san'd layers of limited lateral extent. The clays are generally medium plastic, hard and exhibit extensive ca'lareous cementation.'radational mixtures 95

Other local water courses include Winters Wash and a wash draining a narrow'trip extending a few miles north of the plant site. Figure 7.0-1 shows the locations of rivers and washes relative to the site.
There are. no dams on East Wash, Winters Wash or the Hassayampa River.
There are se'veral small detention dams on Centennial Wash, the 'argest being a.low'eaithfill dam about 45 miles upstream Erom the site, which has a capacity of about 100 acre-feet.'here are several large water storage dams on the Gila River system upstream fr'om the site. The locations of these dams are shown in Figure 7.0-2. Data on these dams are presented in .

The U. S. Geological Survey (USGS) op'crates a water-stage recorder on Centennial Wash that gauges the runoff from 1,810 square miles, and a flood hydrographic recorder on Winters Wash that gauges the runoff from 47.8 square miles. The Centennial Wash, gauge datum is 773.22 feet above msl and is obtained by u'se of a water-stage recorder. The base discharge is 1,000 cubic feet per second, with the flow regulated by several small detention dams. The Winters Wash gauge is a flood-hydrograph recorder located at 1',080 feet msl. The base discharge. is -100 cubic feet per .second, with neither storage nor diversion above the station.

For the period of record (1961' 1977), maximum recorded discharge in Centennial Wash was 14,500 cubic feet per second on July 31, 1961. Maximum recorded discharges in Winters Wash for the period of record (1962 - 1977) was 3,640 cultic feet per second on September 25, 1976. Tables 7.1-1 and 7.1-2 give the peak discharges recorded for Centennial Wash and Winters Wash, respectively.
Maximum recorded discharge of the Hassayampa River, as recorded by a crest-stage recorder located near Morristown, Arizona (whicn gauges the runoff fr'om 774 square miles), was 47,500 cubic feet per second on September 5, 1970. The period of record for the gauge near Morristown includes the water years 1939 - 1947, 1954, 1956 and 1964 -,1977. Table 7.1-3 gives the
~
peak discharges recorded for the Hassayampa River. The datum of the gauge is 1831.16 feet above msl. From October 1938 to June 1947, data is from the water-stage recorder; from June 1947 'to November 1963, there is miscellaneous data only. There are annual peaks for 1947 and 1964 -1965 only.
Maximum observed discharge'f the Gila River, at the USGS gauging station below the Gillespie Dam (which- gauges th'd runoff from 49,650 square'miles),
was,85,000 cubic feet per second on December 28, 1923. The period of record for the Gillespie Dam gauge includes the years 1921 to 1977. (A maximum, discharge of 250,000 cubic feet per second'was estimated to have occurred in February 1891 at the Gillespie damsite.) Table 7.1-4 shows the peak discharges recorded for the Gila River below Gillespie Dam.

I 7.2 Offsite Flood Desi n Considerations The plant site is not susceptible to flooding by the Gila River, the Hassayampa River, or the Centennial Wash. The nearest approach of the Gila River to the site is 6 miles to the southeast; the probable maximum flood state of elevation 776 is 175 feet below the lowest plant grade of 951 at Unit 3. The Hassayampa River is 5 miles to the east, with a high-water level of elevation 942. A topographic ridge between the plant site and the Hassayampa River (minimum elevation 975) provides a natural barrier against site flooding from the Hassayampa River. Centennial- Wash is approximately 5 miles south of Unit 3, with a probable maximum flood le'vel of elevation 888. The only drainage affecting plant design is from, nearby offsite sources and from onsite sources.
Potential offsite flooding sources are East Wash and Winters Wash. Since these washes have no reservoirs upstream from the plant site, flooding could occur only from precipitation. Protection of safety-related
., facilities 'from inundation by offsite flood sources is achieved .by the location of the facilities beyond the extent of flooding. East Wash has been realigned to flow past plant facilities along the east boundary of the site, 7.3 Onsite Flood Desi n Considerations The site is subject to potential flooding from East Wash and Winters Wash.
Flood protection is achieved by site grading such that all Seismic Category.
I facilities will be located beyond the extent of the Probable Maximum Flood (PMF). The ground elevation along the west. side of the site is raised to limit the extent of PMF on the site. A maximum of about 10 feet of compacted. fill was placed in the cooling'tower areas, such that ground between the peripheral road and the power block areas will be above the PMF levels. A drainage channel designed to carry 50 year flood flows" will convey .flood waters from the northern portion of the site, west of the peripheral road to a discharge point south ofthe power block area.
130
'I East Wash has been realigned along the eastern edge of the site to maximize use of the site for other facilities and to limit the extent. of the PMF The normal channel of East Wash has been blocked by an embankment between the two hills on the northern edge of the site. This embankment forces flood flows around the small hill i-.. the northeast corner of the site and cuts off any flow through the 'old channel. An additional embankment has been constructed 'along the eastern edge of the site to prevent flooding of the site .proper. Both embankments are constructed to elevations sufficient to prevent any over topping by a PMF and associated wave runup and wind setup. The East Wash embankments have been constructed of material excavated from the reservoir and power blocks. The elevation of the north-'acing embankment "is approximately 983 feet msl to meet existing contours at the southern end.
The embankments are designed to withstand static and dynamic effects of floods corresponding to the PMF. The outer faces of the embankments are protected from erosion by providing a riprap zone.
8.0 GROUNDWATER The site area (5 mile radius) is in the lower Hassayampa-Centennial groundwater basin. This basin encompasses an area of about 400 square miles, The hydrogeologic profile of the site area is defined by three major sedimentary" units, each having distinctly different lithol'ogic, and hydrologic characteristics. These units, found in most Central Arizona water basins are identified herein as:
~ Upper Alluvial'nit
~ Middle Fine-Grained Unit
~ Lower Coarse-Grained Unit The generalized hydrogeologic profile of the site area is depicted in Figure 8 0-1.
~ A description of the sediments as they relate to the groundwater regime of the site is presented in the following paragraphs.

U er Alluvial Unit This unit consists of primarily silty and gravely sands of varying proportions with interlayered, discontinuous lenses of clays and silty clays. This unit. extend's to a depth of about 30 to 60 feet beneath the site. In'dividual layers are about 3 to. 10 feet thick, and are
'I
. characteristically moderate to poorly bedded. The stratification is typical of sediments deposited in a high-energy fluvial environment.
Primary sedimentary structures identified during the detailed geologic mapping of power block excavations consist of channel cut and fillfeatures.,
The permeability of the upper alluvial unit soils was determined by inflow and outflow (pumping) type field tests. The typical horizontal permeability of these deposits is about 10 gallons per day per square foot (5 x, per second). Because of the extensive stratification, the 10'entimeters vertical permeability (not measured) can be expected to be significantly lower than'he horizontal permeability.
Middle Fine-Grained Unit This unit consists of massive, continuous layers of clays and silty clays, interbedded with layers and scattered lenses of clay'ey silt, clayey san ..
and silty sand. The thickness of the unit is about 250 feet. The upper c'ontact of'he middle fine-grained unit is equivalent to a well-defined boundary between two distinctive depositional environments and can be clearly identified across the site. Locally, the'ontact is transitional where a few scattered lenses of silt and fine sand are encountered. The middle fine-grained unit corresponds to lithozones 3 and 4 of the geologic=
model. The distinction between the two zones in the middle fine-grained unit is based on subtle but definite differences in geotechnical and 133

hydrologic properti.es. Silty clays of medium plasticity predominate in the upper zone (lithzone 4), while clays of somewha" higher plasticity predominate in the lower zone (lithozone 3 -- Palo Verde clay). The two zones are separated" by a relatively continuous coarse-grained soil layer.
The permeability characteristics 'of soils in the upper portion of the unit were evaluated by both laboratory and ,field tests.
. The vertical permeability, de'termined laboratory tests, is on the order of 0.001 gallons
'per day per'quare "foot (5 x 10 centimeters per second) and 0.01 gallons per day per square foot (5 x 10'entimeters per second), respectively.
Lower Coarse-Grained Unit In general, the lower coarse-grained unit is described as a "variably" cemented conglomerate which lies directly on the undifferentiated basement complex. In the site area, the lower coarse-grained unit consists of a tilted interbedded sequence of vol'canic flows and flow breccias, tuffs, tuffaceous sandstones, and coarse-"grained arkosic sandstone. The flow breccias (which may be interpreted as the "variably cemented conglomerate" )
are common throughout the sequence (lithozone 0). Locally mantling this volcanic/sedimentary section are -deposits of moderately to well-lithified conglomerates (lithozone 1). The entire sequence is overlain by an unlithified to poorly-cemented silty sand, sand and gravely sand (lithozone
~~2) ~~~
The . permeability of the regional aquifer was assessed by reviewing irrigation well pumping and performing an aquifer pumping 'test. Yields from irrigation wells which tap the regional aquifer range from 400 to 2,800 gallons per minute. The average specific capacity is 35 gallons per minute per foot of draw-d'own. The aquifer pumping test, performed on irrigation well resulted in a calculated I
transmissivity of 100,000 an'xisting gallons per day per foot and a storage coefficient of 0.005. The pumping rate during the test was 2,360 gallons per minute.
134
8.1 Groundwater Conditions In the site area, the groundwater reservo'ir consists of an extensive regionai aquifer and a local perched water zone, Re ional A uifer In the site area, the lower coarse-grained unit, described above, comprises the regional aquifer that extends to over 400 square miles. The regional aquifer is bounded by the mountain masses that encompass the lower h
Hassayampa-Ce'ntennial area.
The 'primary recharge source to the regional aquifer in- the site area is underflow from upper Hassayampa Valley, north of the site area. The general flow direction is north to south. Reversal of flow direction occurs locally when the groundwater levels are depressed due to pumping for irrigation purposes. Infiltration of'recipitation, surface runoff, and return flow from irrigation in the vicinity of the site comprise a small portion of the total recharge of the regional aquifer. Discharge from the regional groundwater reservoir occurs as underflow to Arlington Valley and pumpage from irrigation wells.
Piezometric levels in the vicinity of the site are at depths ranging from 100 to 250 feet below the ground surface. A water level contour map of aquifer in the lower Hassayampa-Centennial area was constructed thegional by the USGS .and is reproduced in Figure'.1-1. The most conspicuous-hydro'logical features indicated by the water level contours are the large cone'of depression beneath the site, and a broader but shallower cone of depression south of the site. A smaller cone of depression also occurs immediately north of the Palo Verde hills. The cones of depression have been formed by long term pumpage from irrigation wells in the area.
Artesian conditions prevail within the aquifer in the site area.
Confinement is generally provided by the middle fine-grained layer.

Perched Water Zone The Palo Verde site is situated in an area that was under cultivation from about 1950 to late 1975. Water for crop irrigation was pumped from the regional aquifer. Most of the water was consumed by the crops (primarily cotton) through evapotranspiration. The remainder of the water perclated
=
through the upper alluvial sediments and perched on top of the underlying aquitard (middle fine-grained unit). The shape of the perched mound is consistent with the shape of the irrigated area within the site. Water
~
table conditions prevail within the perched water zone.
During the 25 year period of agricultural activity at the site, the prime source of recharge of the perched water zone was excess irrigation water that percolated through the upper sediments. Since 1975, when agricultural activity stopped within the site, the only source of recharge has been precipitation and surface runoff. However; as evidenced by the sharp decline in perched water levels since 1975 (3 feet per year average) local l
natural recharge is insufficient to maintain the perched mound. The decay of the perched water mound is caused mainly by radial flow outward from the center of the mound and some downward leakage through the aquitard.

8.2 Re ional Water Use Water for irrigation is the major use of groundwater in the lower Hassayampa-Centennial area. An average of 78,000 acre-feet per year was pumped during the period 1.'.6 through 1972. The water for municipal and domestic use, also obtained from the groundwater reservoir, is ve'y small.
Annual pumpage for municipalities, livestock; or industrial purposes is less than 1% of the total.
The production history of wells in the lower Hassayampa-Centennial area is compiled in Table 8.2-1. The table ].ists well locations for known active and the annual pumpage rate for each well for the years 1966 through
'ells 1972. A steady decline'f the water levels in the area began about 1950.
due to the increases in pumping of groundwater for agriculture. The water level has declined by as much as 100 feet near the centers of cones of depression during the past 25 years. The water level decline is attributed to pumping of wells and the resultant spread of the cones of depression and consequent interference effects between wells.
8.3 Accident Effec'ts Contaminated water, if accidentally spilled during plant operation, may seep through the ground surface. For this postulate'd occurrence, the contaminated water will'nfiltrate downward through the unsaturated soil and reach the perched water table about AO feet below the land surface.
It will then disperse into the perched groundwater. Further downward movement of water from the base of perched water zone is restricted due to the presence of the Palo Verde clay layer about 200 feet below the ground surface. For the conservative analysis used in this study it is assumed T
that seepage could occur through 'the Palo Verde Clay layer. Consequently, two systems are analyzed for the possible effect of a contaminate'd water spill: the perched water zone and the underlying regional aquifer. The impact of such postulated accidental seepages on the system, and, in particular, on the existing wells located in the 5-mile zone around the site area, is analytically predicted and its consequences are assessed.
