2.0 MAIN COOLING RESERVOIR DESCRIPTION 2.1 GENERAL The Main Cooling Reservoir (MCR) covers an area of approximately four miles by three miles and is formed by a 12. 5 -m il e-lo ng em-bankment with a crest elevation of 66 feet, msl (Reference Dwg.
9Y51 0-H-1151 to 1154).
Natural ground elevation in the reser-voir area varies between 16.0 feet and 28.0 feet.
The Normal Maximum Operating Level (NMOL) is elevation 49 feet.
l The purpose of the MCR is to provide cooling water for condenser p
and auxiliary systems of the Project's power generating units.
l Cool Water is withdrawn from the MCR at the Circulating Water (C.W.) Intake Structure and pumped through the condensers for I
cooling purposes and returned to the MCR via pipeline to the C.W.
l Discharge Structure.
Water Circulation in the MCR for cooling is controlled by interior dikes.
The total length of the interior dikes is about 7 miles.
These interior dikes are subdivided into components:
North Dike, East Dike, West Dike, and South Dike.
All interior dikes have a crest elevation of 52.0 feet, mal.
The interior dikes guide the flow f rom the Circulating Water Dis-charge Structure back to the Circulating Water Intake Structure, j
Recirculating channels excavated in front of the circulating water structures are provided to improve hydraulic ef ficiency in circulating cooling water during low reservoir operating levels (Reference Dwg. 9Y51 0-H-1195).
1 The reservoir level is controlled by the makeup and blowdown sys-tems, and a gated spillway.
The Makeup Water Pumping Station is l
located on the Colorado River.
It provides water to the reser-voir through a 6,000-f t-long pipeline which discharges into the MCR at the Makeup Water Discharge Structure.
The spillway ul-timately discharges into the Colorado River through a 6,000-f t-long discharge channel.
The spillway weir crest is at El. 40 I
feet, surmounted by vertical lift gates 9.5 feet high to El. 49.5 feet.
The blowdown system is connected to the Colorado River J
through a 6,000-f t-long blowdown pipeline.
h 2.2 DAM EMBANKMENT l
The MCR embankment is a zoned earth embankment with an interior slope of 1 vertical o 2.5 horizontal and an exterior slope of 1 vertical to 3 horizontal (Reference Dwg. 9Y51 0-H-1155 and 1156).
An interior berm of varying width is provided along the entire length of the embankment except at a one-mile-long section in the northeast corner of the MCR.
The interior berm elevation varies between 30 to 35 feet.
The interior slope and berm are protected by a 2.5-foot-thick layer of soil-cement.
The exterior slope has also been provided with a 45 to 55-foot-wide berm rising to ele-vation 35.0 feet.
The embankment has a crest width of 16 feet A-3302 01/21/87 and is constructed predominantly of clay.
A 10-12 foot-wide ver-tical sand core has been provided near the embankment centerline.
I The sand core extends along the full length of the embankment centerline from the natural ground surface to about elevation 50.0 feet.
A 145( +)-f oot-wide horizontal sand drainage blanket is provided under the exterior shell of the embankment along se-lected embankment lengths (see Section 2.3.1).
Inspection roads are provided along the downstream berm, at the toe of the down-stream berm, and along the crest of the main embankment.
The roads are paved with asphalt treated limestone.
The interior dikes have a crest width of 12 feet (Reference Dwg.
(
9Y51 0-11-1155).
Both side slopes on the interior dikes are 1 i
vertical to 2.5 horizontal with a 2.5-foot-thick layer of soil-I cement.
Turnaround areas (Reference Dwg. 9Y51 0-11-1170) have been provided at the ends of the interior dikes for inspection I
vehicles.
The embankment is founded on alternating layers of clay and sand.
l The foundation stratigraphy consists generally of four major soil identified f rom top to bottom as clay layer 1 (sometimes I
strata subdivided into units la and Ib), sand layer 2, clay layer 3, and sand layer 4.
The major shallow sand zone, stratum 2, is gener-l ally present under most of the embankment and is the principal path of seepage under the embankment.
There are wide variations in the stratigraphy along the embankment particularly in the thickness and permeabilities of strata 1 and 2 which affect un-derseepage and its control 2.3 UNDERSEEPAGE CONTROL l
2.3.1 General l
Seepage unde r the embankment is controlled by the following mea-I sures:
A.
Construction borrow areas in the reservoir area for l
original embankment construction were restricted to I
preserve the natural top clay (stratum 1) and to pre-vent the exposure of the underlying sand (stratum 2) l within 920 feet of the embankment.
B.
Iforizontal sand drainage blankets are provided under the downstream (exterior) shell of the embankment under selected sections of embankment.
C.
Relief wells are provided at varying spacing and de-grees of penetration around the MCR.
2.3.2 florizontal Sand Drainage Blanket A horizontal sand drainage blanket under the landward side of the i
embankment has been provided to intercept the seepage in area i

I 2.5 MAKEUP PUMPING FACILITY I
The Makeup Pumping Facility consists of a Makeup Pumping Station; Makeup Water Pipelines and the Makeup Water Discharae Structure.
The Makeup Pumping Station is located along the west bank of the Colorado River and supplies the MCR with water f rom the river.
'I The pumping station has a total pumping capacity of 1,200 cubic feet per second (cfs) provided by four 240 cfs pumps and four 60 cfs pumps.
8 A-3302 01/21/87 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
l 1
l l
l The Makeup Water Pipeline consists of two 9-foot-inside diameter prestressed concrete (AWWA C-301) pipelines which extend 6357 feet from the Makeup Pumping Station to the reservoir embankment.
For the most part joints in the pipeline between pipe segments are of the bell and spigot type with gasket.
For joints in pipe I
buried in the embankment, elastomeric joint liners were installed to improve watertight reliability.
The pipelines are placed in a l
common trench; excavated to elevation -5.4 feet.
The pipeline is i
bedded on a 2-foot-layer of free-draining coarse sand which meets the general requirement of ASTM C-33.
l The Makeup Water Discharge Structure is a reinforced concrete structure location on the inside face of the MCR embankment.
It is designed to convey water f rom the makeup pipelines to the MCR.
l The makeup discharge structure is constructed as a combination I
plunge pool and baffled chute to dissipate the excess energy of the water as it leaves the makeup pipeline.
A discharge pilot l
channel at elevation 14.0 feet if provided within the MCR at the base of the Makeup Water Discharge Structure to minimize erosion I
and scour during the initial filling (Reference Drawing 9Y51 0 1191).
I The Makeup Water Facility is used intermittently, and can be shutdown and drained for repairs or inspection without af fecting
}
plant operation.
2.6 BLOWDOWN RELEASE FACILITY The Blowdown Release Facility consists of an intake chamber in-tegral with the spillway structure and a discharge pipeline to l
the Colorado River (Reference Drawings 9Y53 0-11-2120 and 9YS8 0-
!!-3100).
The intake chamber invert is at elevation 29.0 feet.
3 It is located upstream of the ogee on the west side of the spill-p way.
The blowdown pipeline is a 78-inch-diameter prestressed l
concrete (AWWA-C-301) pipe and is located on the west side of the spillway chute.
For the first 118 feet downstream of the intake, the pipeline is embedded in concrete and runs parallel to the spillway chute.
The blowdown pipeline discharges into the Colo-rado River through seven ports located downstream of the spillway channel on the west bank of the river.
2.7 SPILLWAY RELEASE FACILITY The Spillway Release Facility is located in the southeast corner of the MCR at station 266+00.
The spillway facility consists of an Approach Channel, an ogee Section, a chute Section, Stilling Basin, and a Discharge Channel (Reference Drawings 9Y51 0 1180).
The ogee section is a 31.5-foot-wide, 51-foot long gated concrete gravity spillway.
The spillway is provided with four electri-cally operated 9.5-foot-high by 6-f oot-wide vertical lift gates at the crest of the ogee section.
The ogee crest is at elevation 1
A-3302 01/21/87 l
40.0 feet and the top of the gates is at elevation 49.5 feet.
The spillway slide gates shall be lubricated and exercised (manu-ally and mechanically) through their full travel at least every
[
6-months.
The stop log barrier which has been provided directly L
upstream of the gates shall be utilized for maintenance of the spillway gates when reservoir pools exceed the ogee overflow ele-vation 40.
The purpose of the Spillway Release Facility is to pass flood discharge from the MCR to the Colorado River.
The approach channel conducts flow to the ogee crest; the ogee crest and gates guide and regulate the amount of water released through the spillway; the chute guides the discharge waters from ogee 5
crest to the stilling basin; the stilling basin dissipates the kinetic energy of the water before its entrance into the dis-p charge channel; and the discharge channel conducts the floodwater L
to the Colorado River.
The stilling basin is located about 290 feet downstream of the embankment centerline and is approximately 85 feet long.
The invert of the stilling basin is at elevation -
f 7.0 feet.
A 150-foot wide excavated trapezoidal discharge chan-nel extends from the stilling basin to the Colorado River.
r The foundation soil at the spillway consists of stratum la L
sandy clay and clay, stratum 2 - silty fine sand, stratum 3 -
stiff plastic clay, and stratum 4 - fine sand.
To prevent the g
buildup of uplift pressures beneath the spillway chute and still-
[
ing basin a 4.5-f oot-thick bedding of sand (Type-I-fill:
sand conforming to ASTM C33-74) has been provided under the full width of the concrete structure.
Perforated 6-inch-diameter drain r
piped,' embedded in Type II material (Gravel conforming to ASTM
(
C33-74), are installed in the bidding material.
The drain pipes are located longitudinally under the upper portion of the chute and transversely in the lower portion of the chute and underneath the stilling basin.
The stilling basin is riprap-lined and ringed by relief wells.
2.0 CIRCULATING WATER INTAKE AND DISCHARGE SYSTEM The Circulating Water System (CW) draws cool water from the MCR via the intake structure and delivers it to the condensors (Units 1 and 2) through eight 96-inch prestressed concrete pipelines I
which pass over the embankment (Reference Drawings 9Y51 0-H-1195, i
1 5 3 4 11 1, 1534H-13-5).
The pipes are fabricated in conformance
(
with AWWA C301.
The warm water is returned to the MCR via four 138-inch diamator pipelines which cross over the embankment and terminate at the Discharge Structure seal well.
Four interior
[
dikes direct the water around the MCR before it returns to the Intake Structure.
The CW Intake and Discharge Structures are common to Units 1 and
(
2.
The CW pumps for each unit are arranged symmetrically on either end of the intake structure.
The auxiliary pump bay, com-mon to Units 1 and 2, provides suction f or the open loop auxil-iary cooling water, seal water, screen wash, and essential cool-
[
A-3302 01/21/87 -
'l
'I 1
ing pond makeup pumps.
A sealing weir is located at the Dis-I charge Structure to maintain a siphon on the system in the event of low reservoir level.
i l
5 The Circulating Water Intake Structure is a large reinforced con-crete structure approximately 100 feet by 300 feet in plan lo-cated 191 feet from the embankment centerline at station 4+10.5 in the reservoir.
The structure is supported on a reinforced 4
concrete mat founded at elevation 0.0 feet.
The Intake Structure consists of sixteen screened intakes with each pair feeding one main circulating water pump bay.
There in one auxiliary bay with ll two screened intakes.
The water pumps discharge into the Circu-W lating water pipes.
The eight 96-inch-diameter Circulating Water pipes (four per gen-I erating unit) are supported by concrete platforms from the Intake Structure to the embankment and pass over the MCR to the embank-ment.
At the embankment the pipes are supported on a concrete I
chute.
As the pipes pass over the embankment they are inclined downwards and become buried in the berm at the downstream toe of the embankment.
At the toe of the berm, pairs of 96-inch lines i
merge to form four 138-inch-diameter pipes, two for each gener-ating unit.
Each generating unit is then supplied by 2 pipes which are connected to the condenser through a common header.
The circulating water is returned to the MCR by two 138-inch-diameter pipes for each generating unit.
The four pipelines emerge at the berm of the embankment and pass up over the embank-ment and down the interior embankment slope on an exposed con-crete chute.
The pipelines terminate at the Discharge Structure.
The Discharge Structure is a reinforced concrete structure ap-proximately 32 feet by 102 feet in plan located 160 feet from the I
embankment centerline at station 651+76.76 in the reservoir.
The structure is founded at elevation 4.75 feet.
The discharge structure acts as an energy dissipator and also controls the cir-I culating water discharge level to a minimum elevation of 35.0 feet.

Areas which are observed to be excessively wet or soft, areas with noticeable seepage and boils, areas of erosion, areas of shallow slides or sloughing, areas of transverse or longitudinal cracking, and areas of deteriorated soil-cement slope protection l
shall immediately be reported to HL&P.
HL&P shall take appro-priate action as advised by the MCR Resident Engineer.
1 Areas of erosion shall be repaired by correcting unsatisfactory la drainage, removing all unsuitable material, filling the eroded g
area with approved material in 12-inch lifts, compacting the lifts with approved equipment and fertilizing and reseeding the repaired area.
Insofar as possible, all fills shall conform to original project specifications.
Shallow slides or sloughing shall be repdired with a method de-I termined to be appropriste on a case-by-case basis.
The repair require changes in the local drainage pattern.
Repairs may mav ia_.ude recompacting the soil into the slide area, locally flat-tening of the slope, use of stabilized recompacted soil, or other alternatives.
Cracks shall be repaired by cleaning loose raaterial and water from the cracks, filling with approved material, and compacting i
the material into the cracks.
Repair of cracks under paved areas will require removal of contiguous pavement and repair of the pavement to original specifications.
Deteriorated soil-cement shall be repaired by removing deterio-rated material, cleaning affected area, and replacing soil-ce-E ment.
For soil cement repairs, material conforming to the origi-3 nal specification shall be used as a minimum.
Lean concrete may also be used for such repairs.
Vegetation shall not be permitted to grow on soil-cement slope protection.
5.3 PRESSURE RELIEF WELLS Relief wells installed around the downstream (exterior) perimeter of the reservoir dam embankment will require periodic maintenance in order to maintain the efficiency of the wells.
This work may I

l.
(
be performed by the MCR Resident Engineer, HL&P general mainten-ance crews, or by specialty contractors as appropriate.
Mainten-ance tasks are outlined below:
5.3.1 Contact Surfaces of Outlet Flap Valves All flap valves, flap gates and check valve seats and gaskets should be cleaned with a plastic knife and/or scrub pad to remove the buildup of organic or chemical deposits.
In addition, the body of the PVC check valve should deposits.
be flushed clean of any 5.3.2 Manholes and Well Identification h
All manhole covers shall be kept in place and secure.
All wells and manholes shall be kept clearly numbered at all times.
(
5.3.3 Sediment Soundings All relief wells shall be sounded for sediment accumulation in
[
the bottom of the well every two years.
Any well having over one foot of sediment accumulation should be cleaned of sediment with j
high pressure water jet and a convential driller's washwate r
)
" tee".
Cleaning of sediment from wells should be conducted by an
(
experienced relief well or drilling contractor to minimize the possibility of well damage during the cleaning operations.
5.3.4 Redevelopment Relief wells should be redeveloped if well flow decreases to be-low 80% of the long term average flow for that particular well after adjusting for MCR pool and landside groundwater levels.
the relief wells should be redeveloped by surging with a double surge block, chemical treatment and horizontal jetting as de-scribed below.- This work should be performed by an experienced relief well contractor.
It is not necessary to immediately redevelop those wells whose flows have decreased to below 80% of the long term average flow unless nearby piezometers show a marked rise or if factors of I
safety fall below 1.5.
Redevelopment of wells can be deferred until there are a sufficient number of wells r.equiring attention to let a contract for redevelopment of multiple wells.
Redevelopment should begin by first plugging the discharge pipe.
Then a mixture of 3 lbs sodium tripolyphosphate per 100 gals of water and 1/2 lb of chlorine (treated for calcium removal with 4.75 lbs of soda ash to 5.5 lbs chlorine) per 1000 gal of water t
(
should be agitated with a double surge block.
the double surge block should be lowered into the bottom of the well and operated up and down at a rate of 2 to 3 ft/sec over a 4 to 5-ft increment A-3302 01/21/87 -

I of the well screen for a period of about 10 min.
Then, the surge block should be raised to the next increment and the process re-peated.
Then the chemical solution should be allowed to soak for about 24 hrs.
Afterwards, a horizontal water jet at a pump pressure of approxi-mately 100 psi, consisting of four evenly spaced 1/4-in. diameter nozzles, should be operated with the jet water containing 30 lbs of sodium tripolyphosphate and 1/2 lb of t reated chlorine per every 1,000 gals.
The jet tool should be rotated once every 10 secs, raised 1 inc. and then rotated again, two cycles from the I
bottom to the top of the screen.
Simultaneous with jetting, the wells should be pumped at a rate approximately 1.25 times the number of gallons per minute entering the well through the jet I
tool.
Following jetting, any sediment in the well should be re-moved as described above in paragraph 5.3.3.
5.3.5 Replacement of CMP Outflow Pipes and Metal Flap Gates Many project relief wells are equipped with corrugated metal out-flow pipes and metal flap gate outlets.
These items will even-I tually corrode and require replacement.
When the outlet pipes corrode they shall be replaced with PVC pipe with a new flapper outlet.
It is not necessary to replace the entire outflow pipe from the ditch to the wellhead.
A PVC insert can be used and I
cemented,in place at the wellhead manhole.
5.3.6 Manhole Maintenance Corrugated Metal Pipe (CMP) manholes damaged by mowing opeations that cannot be repaired in-kind shall be replaced above ground I
level with concrete pipe to a height 2 feet above the ground surf ace and fitted with a manhole cover as shown on Figure 4 of Attachment 1.
Soil around manholes should be regraded if erosion or settlement has occurred.
All CMP manholes with poor mastic I
coating should be periodically recoated with mastic to retard rusting.
This applies to external and internal manhole surfaces from the top of the manhole to the wellhead.
5.3.7 Splash Pads Splash pads shall be inspected for undermining.
Repairs shall i
utilize filter aagregates and filter cloth and mastic appropriate to the location to effect in-kind repairs.
5.3.8 Miscellaneous Parts Insofar as practical, any relief well part that proves unservice-able shall be replaced with assemblies as specified in Attachment I
1.
I I
A-3302 01/21/87 l
5.3.9 Replacement Wells Deterioration of CMP manholes below the ground surface or repeti-tive need for redevelopment of individual wells may signal the need for total replacement of the well in cuestion.
If such ac-tion appears to be required, the new replacement wells shall be installed as shown on Figure 4 of Attachment 1 by an experienced H
relief well contractor.
r 5.4 DRAINAGE DITCHES AND STRUCTURES L,
Maintenance of drainage ditches and st ructures shall include:
(1) periodic removal of vegetation, sediment, and debris; (2)
{
grading or relocation to prevent standing water; (3) repair of eroded areas, ditch slopes, concrete linings, riprap, culverts, berm laterals and relief wells.
All permanent drainage ditches and structures shall be maintain-I ed, including the plant area drainage ditches, sewage effluent and dewatering ditch, berm ditches, toe ditches, berm laterals, I
culverts, riprap area around the spillway stilling basin, spill-way discharge channel, blowdown acess road ditch, exftting and I
relocated Little Robins Slough, and all connecting drainage ditches and structures.
I Sediment, vegetation, and debris removed from the drainage ditches and structures shall be disposed of in spo.1 areas desig-l nated by Site Engineering staff.
Standing or stagnant water shall not be permitted in drainage j
ditches and structures.
Drainage ditches and structures may need regrading or relocation to eliminate standing water.
Areas of erosion damage and damaged or deteriorated ditch slopes, I
concrete linings, riprap, culverts, berm laterals, and all other drainage structures shall be repaired to original specifications.
l Site Engineering shall be immediately notified of the presence and location of all sand boils in the drainage ditches.
Site Engineering, in cooperation with the MCR Engineer, shall investi-gate all sand boils, find an appropriate way to maintain a re-duced head on the boil to eliminate piping and provide technical guidance for all repairs or outline programs of continued obser-vation.
Periodic removal of vegetation and sediment specified in this section shall be performed at four month intervals.
Additional or more frequent removal of vegetation and sediment shall be per-formed to maintain inspectability of the ditches for seepage phe-nomena.
A-3302 01/21/87 r
L 5.5 MOWING AND VEGETATION CONTROL r
L 5.5.1 General Proper operation of the MCR requires that the grass cover and I
other vegetation growth around the MCR be kept under control.

6.2 RESPONSIBILITY I
The MCR Resident Engineer will maintain an Instrumentation Team consisting of a surveyor and an appropriate number of qualified inspectors.
The instrumentation team, under the supervision of I
the MCR Resident Engineer, will conduct the field activites and have initial responsibility for management of monitoring data.
The MCR Resident Engineer will in turn report to HL&P Management.
6.3 INSTRUMENTATION MONITORING Instruments have been installed to check the performance of the I
Main Cooling Reservoir during the initial filling and normal operation.
The type of instruments to be monitored include structural benchmarks and settlement points, piezemeters, relief wells and inclinometers.
Detailed procedures for monitoring in-cluding frequency of readings, recording of readings, control of readings in error, data collection and management, and transmit-tal of data are covered in Attachment 1.
Data reduction and computer storage of monitoring data will be performed by the MCR Engineer.
A description of the on-site com-I puter data base system is given below (or in Section 6.6).
The instrumentation data periodically gathered shall be assembled into a data package with a cover sheet entitled "Geotechnical Monitoring Program - Data Control Form."
A copy of the data i
package shall be transmitted f rom the MCR Engineer to the Site Engineer with the originals going to HL&P's Record Management System.
The MCR Engineer shall maintain copies of all field re-I cords of geotechnical instrumentation monitoring data and cor-respondence in a working file on site.

Data Record - records of maintenance activites or inci-I dents including locations, stations, and dates for events which may affect instrument accuracy and report-ing should be noted; I.
Data Transmittal and Management - improvements in the procedures of data transmittal, data reduction, and data computer storage should be noted if appropriate.
I 6.5 INSTRUMENTATION - MAINTENANCE Based on the inspections discussed above, the MCR Engineer shall I
identify maintenance needs for all geotechnical instruments on the MCR and related facilities.
A list of maintenance needs shall be transmitted to HL&P Operations for action.
A discussion I
of instrument maintenance activites is included in Section 2.4 of Attachment 1.
Each piezometer shall be slug tested annually by filling the riser with water to the top of the pipe and recording the time for the pipe water level to fall 5 feet or to its origi-I nal level, whichever is achieved first.
A log of slug test re-sults shall be kept as part of site files.
6.6 COMPUTER DATA BASE SYSTEM All geotechnical data gathered at the STP site is permanently I
stored on a computer based data management system.
The software developed for this purpose, GEMP (Geotechnical Engineering Moni-toring Program) also processes the stored data and provides the user with tabular or graphical output which is typically in the I
form of time histories for each instrument.
To ensure immediate availability of data for engineering evaluations during the fill-ing period, a specific program, HIMS ( Harza Instrument Monitoring System), was developed for the MCR instruments.
This program is A-3302 01/21/87 I
/
L
[
resident on a dedicated microcomputer system at the STP site and has the capability to accept electronic data entry.
HIMS pro-vides output in formats suitable for use in day-to-day evalua-tions during filling.
I 6.7 DATA ANALYSIS L
The MCR Resident Engineer will be responsible for examination and evaluation of all observation device data.
While conducting data
(
collection activites, the MCR Engineer will possess the previous monitoring period 's readings.
Comparison of this data during monitoring operations will immediately reveal any anomalies in
[
the readings.
Once information is entered into the computer data base system, the MCR Resident Egineer will review the performance of all the instrumentation over time.
A review of this data could reveal trends indicative of the development of potentially critical conditions.

A-3297 01/22/87 FL 7.0 OPERATION OF RESERVOIR MECHANICAL SYSTEMS DURING AN EMER-GENCY 7.1 SPILLWAY The spillway gates are mechanically operated with provi-
[
sions for manual operation in cases of emergency.
The f ailure of the spillway gates to operate during severe flooding (critical precipitation on reservoir surface) will not cause failure of the embankment.
The embankment is designed to withstand the effects of the standard project storm coincident with the probable maximum hur-ricane wind with the gates inoperative.
The MCR 2ngineer
[
will notify HL&P operations should spillway use be re-quired to remove excess rain water or to lower the reser-voir level for other emergency conditions.
7.2 MAKEUP DISCHARGE STRUCTURE The reservoir makeup facilities are required to divert
[-
water f rom the Colorado River into the Cooling Reservoir to replace water lost to evaporation, blowdown, and seepage.
During MCR emergency, the MCR Engineer shall
{
notify HL&P operations to stop pumping.
7.3 BLOWDOWN OUTLETS During MCR emergencies the blowdown outlets shall be used to lower the reservoir level.
[
7.4 CIRCULATING WATER SYSTEM The embankment area adjacent to the circulating water
[
system will be caref ully monitored for any signs of unusual conditions arising from the operation of this system.
Should unusual conditions develop, appropriate action will be taken by HL&P operations under the techni-
[
cal guidance of the MCR Engineer.
HL&P operations will be advised of any MCR emergency and, if a sudden drop in reservoir level is apparent, appropriate action will be
[
taken with respect to the operation of the circulating L
water system.

1.6 FILLING PLAN The impoundment of water in the MCR, per current plan, is to be attained in
{
three stages, with.approximately constant Reservoir Levels (R.L.) in between filling periods.
f 1.
During Stage I filling (Completed in September 1983) R.L. was i L
raised to El. +28.0 ft. M.S.L. (Approx.);
11.
During Stage !! filling (Completed in November 1985) the R. L.
{
was raised to E1. +35.0 ft. M.S.L. (Approx.);
the R. L. is scheduled to be raised iii.
During Stage III filling,(Approx.) and maintaining this R. L.
to El. +49.0 ft. M.S.L.
{
for a duration suf.ficiently long to monitor the performance of MCR embankment and related facilities in order to evaluate the structural integrity and stability of the MCR embankment at r
this reservoir level. Later, the reservoir level will be
(
lowered to a level between E1. +40.0 ft. M.S.L. and El.
+45.0 ft. M.S.L. to support normal plant operation where El.
+45.0 ft. M.S.L. will be the Normal Plant Operating Level.
Schedule for Stage III filling may be revised to permit modification work to the MCR to be implemented as specified in 9YS10HS1013.

9Y510YS1004 Rev. 3 2.5.4 Relief Wells 2.5.4.1 Introduction P
L Relief wells have been installed around the downstream perimeter of-the Main Cooling Reservoir embankment to relieve excess pore pressure in the permeable f
soil layers beneath the embankment. The relief wells are free-draining and self-contained. The monitoring specified herein consists of:
A.
The periodic measuring of the rate (volume per unit of time) of water flow from the discharge pipe of each flowing well.
B.
The periodic light maintenance of the relief well flap valve assembly on the discharge pipe.
The location of relief wel'l's are tabulated in Table 4 by their station number along the Main Cooling Reservoir embankment.
2.5.4.2 Monitoring Procedures Flow from relief well discharge pipes shall be measured using a graduated clear glass container and stopwatch. The flow she.Il be measured without raising the flap valve at the end of discharge pipes. However for the next (after November 25,1985) two cycles of monitoring, the rate of flow from the relief wells shall also be measured after raising the flap valves and allowing the flow to stabilize to a steady stream. Flowrate can be measured in any unit, but in all cases the readings shall be converted to and reported in gallons per minute (gpm). The effluent shall be visually checked for fines by holding the container against light. A qualitative consnent (e.g., highly turbid, lightly turbid, or clear) shall be noted on the form. If silt is present in the discharge pipe due to drainage ditch flooding, it shall be so noted. The flow shall be measured at least twice to achieve repeatability.
r The rate of flow, or if not flowing, an appropriate note, e.g. " DRY, "UNDER L
WATER." " INACCESSIBLE." shall be recorded on Relief Well Flow Report (Figure 12). Water level in the Reservoir at the time of monitoring relief well flow shall also be noted on the Flow Report Form.
The Contractor may, at his discretion, but with prior written notification to l Bechtel, use alternate monitoring procedure (s) for relief wells that are accessible, but may have their discharge pipes temporarily underwater.
I,'
At the time the relief well flows are checked, the discharge pipe flap valves shall be inspected and cleaned as necessary. Silt, mud, and grass shall be I
cleaned from the hinge assembly. The metallic flap valves (pre-1981) shall be l worked so as to move freely, and a light coating of light machine oil or penetrating oil (e.g., WD-40 or equivalent) shall be applied. Major maintenance problems, such as damage to the discharge pipe, shall be reported in writing to the SEM.

r 2.5.5 Inclinometers L
2.5.5.1 Introduction
{~
Inclinometers have been installed at selected stations on the Main Cooling Reservoir embankment to monitor horizontal ground movement at those stations.
Each of the mor,itored stations have three inclinometers - one at the r'
embankment crest, one on the upstream face at an approximate elevation of 50 feet, and the third one on the embankment downstream berm.
Ll 2.5.5.2 Location The inclinometer sets are located at approximately Stations 262 + 00, 280 + 00, 318 + 20 and 341 + 50 of the Main Cooling Reservoir embankment and tabulated by their numbers in Table 5.
2.5.5.3 Method of Measurement The inclinometer sensor, referred to as a torpedo, is moved through the permanently installed aluminum or plastic casing along four internal longitudinal grooves which guide the torpedo. Variations detected by the tilt
/
sensor show on a portable indicator and are read and recorded.
Procedures for performing inclinometer measurements shall be as follows:
A.
The groove or slot orientation shall be recorded. The slots are
{
designated as A+,
A, B+, and B-as shown on Figure 6.,
8.
With the inclinometer sensor, cable and readout unit connected.
the torpedo is lowered with its upper wheel in the A+ groove
[
(for a biaxial device this will give inclinations for the A+ and B+ directions).
[
[

1852W/0048W N
9Y510YS1004 Rev. 3 C.
The torpedo is then lowered to a reference point established during calibration. The cable may be fixed by an extension cable clamp while awaiting stabilization of the readings on the indicator unit. Once stabilized, the complete readings are recorded.
D.
The cable is then pulled up 2 feet, and another reading taken.
Readings are continued in this manner at 2-foot increments until the top of the casing is reached.
E.
After reaching the top of the casing the torpedo is removed and rotated 180 degrees then is inserted back into the grooves
- I (upper wheels in the A-groove). The instrument is then ready to record the inclination with respect to the A-and B-directions.
F.
The procedures outlined in steps 8 through D shall be repeated.
2.5.5.4 Frequency of Monitoring The inclinometers shall be monitored once a month during prefilling period, once every two weeks during filling, on a monthly basis for one year after the Reservoir is full, and once every two months until 5 years. They shall be I,
monitored quarterly thereafter (see Table 1).
2.5.5.5 Reporting The inclinometer readings shall be reported to the Site Engineering Manager on the Inclinometer Data Form (Figure 11), and transmitted under the Data Control Form (Figure 7).
- 2. 6 RECORDING OF READINGS 2.6.1 General Readings shall be entered by the Contractor's field personnel on the forms as I specified therein, and the forms shall be checked and signed by the HRE.
