SUBJECT:
COMANCHE PEAK STEAM ELECTRIC STATION REQUEST FOR AMENDENT OF CONSTRUCTION PERMITS CPPR-126 AND CPPR-127
Dear Dr. Denton:
Texas Utilities Generating Company ("TUGC0") hereby requests that, pursuant to Section 185 of the Atomic Energy Act of 1954, as amended, and the regulations of the Nuclear Regulatory Commission (10 CFR Part 50), Condition 3.E.(8) in Construction Permit Nos. CPPR-126 and CPPR-127 for the Comanche Peak Steam Electric Station be amended to authorize withdrawal of groundwater during construction for an additional. year.
Construction Permit Condition 3.E.(8) provides, in pertinent part, as follows:
(8) The rate of groundwater withdrawal during construction of the facility shall not exceed 250 gpm. With-drawal of groundwater shall be reduced to an annual average of 30 gpm at the end of five years.
Specifically, we request that the above language from Construction Permit Condition 3.E.(8) be modified by the substitution of the word "six" for the word "five," thus modifying the condition to provide that "(w]ithdrawal of groundwater shall be reduced to an annual average of 30 gpm at t
the end of six years."
Under the tenns of Condition 3.E.(8) as presently written, TUGC0 would be required to reduce groundwater withdrawal to 30 gpm on December 19, 1979.
In' view of certain delays which have been 7906220Zm.,,
TXX-2995 June 15, 1979 experienced in construction, such a drastic reduction of groundwater withdrawal on that date would cause substantial project delays and cost increases. The delays in construction are attributable to several factors which have been discussed with the Staff, including new NRC licensing requirements, increased project scope and complexity, additional and more stringent design criteria, and incorporation of modifications required as a result of operating experience at other plants.
Ile have evah:atad the incremental impacts c.ssociated with an additional year of groundwater withdrawal at the 250 gpm pumping rate, and have concluded that the additional year of groundwater withdrawal at the higher rate will have no significant impacts.
Attached hereto are data reflecting recent groundwater withdrawal at the site, data and the evaluation of the Texas Department of Water Rasources relating to offsite water wells, and a status report on the surface water treatment facility which TUGC0 will cons +,ruct at the site.
In this latter regard, we anticipate that the treatant facility will be available for operation in arproximately June,1980.
Since the requested amendment to authorize withdrawal of groundwate for an additional year involves no significant hazards consideration and no undue risk to public health and safety, it is respectfully requested that the Commission dispense with the notice and publication requirements as pennitted under Section 189a of the Atomic Energy Act of 1954.
Because this amendment request involves a single environmental issue and does not involve a significant hazards consideration, I
we have determined thes are class.III and class I amendments for units one and two respectively. We have therefore enclosed a check in the amount of $4,400 ':c cover the required amendent fee as required by 10 CFR Part 1%

The delays in construction are attributable to several factors which have been discussed with the Staff, including new NRC licensing requirements, increased project scope and complexity, additional and more stringent design criteria, and incorporation of modifications required as a result of operating experience at other plants.
We have evaluated the incremental impacts associated with an additional year of groundwater withdrawal at the 250 gpm pumping rate, and have concluded that the additional year of groundwater withdrawal at the higher rate will have no significant impacts.
Attached hereto are data reflecting recent groundwater withdrawal at the site, data and the evaluation of the Texas Department of Water Resources relating to offsite water wells, and a status report on the surface water treatment facility which TUGC0 w'll construct at the site.
In this latter regard, we anticipate that the treatment facility will be available for operation in approximately June, 1980.
Since the requested amendment to authorize withdrawal of groundwater for an additional year involves no significant hazards consideration and no undue risk to public health and safety, it is respectfully requested that the Commission dispense with the notice and publication requirements as pemitted under Section 189a of the Atomic Energy Act of 1954.
Because this amendment request involves a single environmental issue and does not involve a significant hazards consideration, we have detemined these are class III and class I amendments for units one and two respectively.

Dear Mr. Coffman:
Re:
Request for evaluation of ground-water pumpage, Somervell and Hood Counties, Texas This is in response to your letter of February 27, 1979.
For many years, eater levels in the Trinity Aquifer in north-central Texas have decliled steadily, especially in the areas of heavy in-dustrial and municipal pumpage such as the Dallas-Fort Worth Metroplex and along and wost of Interstate 35 south of Dallas - Fort Worth to Temple and Belton. Declines in these downdip areas have totaled several hundrel feet in this century and are continuing at rates of 5 to 10 feet,;er year.
In Hood and Somervell Counties, nearer the outcrop and recharge area, water-level declines, though still significant, have been much less, especially in recent years. Declines generally have averaged 1 to 3 feet per year in the areas of heavy pumpage, e.g., near Granbury and Glen Rose. Departmental records covering recent years indicate there has been a continuing increase in pumpage of ground water in thene two counties, both for municipal and industrial supplies. 'Ihis incraased pumpage has led to an acceleration in water-level decline j
rates, especially near the areas of concentrated heavy pumpage around Glen Rose, Granbury, and the Comanche Peak Steam Electric Station (CPSES).

Mr. H. B. Coffman April 6, 1979 Page 2 In Hood County, annual municipal and industrial pumpage more than doubled from 1971 to 1975, increasing from 192,079,459 to 411,476,522 gallons.
Pumpage is continuing to increase, especially by the City of Granbury.
Granbury's annual pumpage increased another 60 percent during the period 1975 to 1978, from 143,989,413 to 227,775,000 gallons.
Annual municipal and intistrial pumpage in Somervell County increased only slightly from 1971 to 1974:
57,481,000 to 66,180,000 gallons; but doubled in 1975 with the addition of pumpage at CPSES. Annual pumpage by the City of Glen Rose almost doubled from 1975 to 1978, from 61,905,500 to 113,959,30.0 gallons. Other municipal and industrial pumpage (including CPSES pumpage) in Somervell County in 1978 was 101,310,700 gallons, making the County total for 1978 215,270,000 gallons.
Between 1970 and 1974, water levels in observation wells measured by the Department in Somervell and Hood Counties showed an average decline rate of 2.4 feet per year. From 1974 to 1978, the average decline was 4.9 feet per year, and almost all wells measured in the two counties showed a significant increase in decline rate.
The 4 water-level observation wells your company measures at CPSES have shown average decline rates of 6.1 to 11.3 feet per year from 1975 to 1978. These wells are located within 2 miles of the center of the CPSES well field, which has averaged pmducing about 155 gallons per minute over the 4 years. Similar decline rates can be expected to continue as long as this rate of pumpage is maintained.
If pumpage is reduced significantly, the rate of decline should slow down, but water levels will continue to decline as long as the CPSES wells and other i
industrial and municipal wells in the Hood - Someryc11 County area, and, of course, the many municipal and industrial wells in the far downdip area, continue to produce large amounts of gmund water from the Trinity Aquifer.
A complete cessation of pumpage from the CPSES wells would probably kr.l :.v at 1 cast a short term recovery of water levels in the immediate e

Hopefully this infomation will be of use to you. Please contact us if you have any questions.

PLANNED SURFACE WATER TREATMENT FACILITY l

~
COMANCHE PEAK STEAM ELECTRIC STATION REVERSE OSMOSIS WATER TREATMENT FACILITY I.
System Description
To mitigate the possible consequences of groundwater pumping at CPSES, Texas Utilities is planning to install a Surface Water Treatment Facility. This treatment facility will take water from Squaw Creek Reservoir at the Circulating Water Intake Structure.
Water will be supplied from either a supply pump, to be added at the intake structure, or from the existing screen wash pumps.
This water treatment facility will consist of a pretreatment system for chlorination and removal of suspended matter, and a Reverse Osmosis System for removal of dissolved solids. The treatment facility will consist of two (2) 50% capacity trains which will produce a combined maximum of 300 gpm of product water.
The supply pump or existing screen wash pumps will supply approximately 430 gpm to the pretreatment system. The pretreatment facility provides for combined settling, filtration, collection, and discharge of suspended matter. Chemicals to aid settling and for chlorination are supplied from a chemical feed system to be located at the pretreat equipment. The addition of chemicals will be automatically controlled to adjust to varying flow rctes.
Feed concentrations of the chemicals will be adjusted periodically to meet changing inlet water conditions.
Each 50%
capacity pretreat unit will supply 200 gpm (400 gpm combined maximum) to the R0 equipment by gravity feed.
Flow from the pretreatment system will' supply a water storage tank j
to control changes in flow rates.
Two (2) 50% capacity transfer j_,
pumps will take their suction from the storage tank. These pumps l
will discharge to a fine particulate filter (cartridge filter) for l
u
e '
removal of any remaining suspended matter. The R0 modules will be supplied by booster purips which will be located just downstream of the cartridge filters. Chemicals will be injected at the booster pump suction to control pH and minimize R0 module fouling.
Chemical injection at the booster pump suction will be automatically controlled according to flow conditions.
The R0 product flow of 300 gpm will discharge to a combined degasefier and product clearwell. Forced draft degasification will be necessary to remove C02 and to raise the pH level.
Transfer pumps taking suction from the product clearwell can discharge to three points:
- 1) inlet to the existing demineralizer trains, 2) potable water storage tank, and 3) R0 booster pump suction.
The 300 gpm product flow will match the design capacity of the existing demineralizer system. The normal supoly for the demineralizer would have come from the ground water wells currently in use at CPSES. Once the surface water treatment facility is operational, it will become the normal supply for the demineralizers.
It will also be possible to supplement the potable water system during periods of high demand. A control system will allow simultaneous supply to any of the three possible discharge points depending on the demand.
Low-volume Wastewater from the RO unit will be discharged into the Circulating Water System. This discharge will be in compliance with State and Federal water qutlity permits.
l II.
Schedule On April 16, 1979, Texas Utilities issued a purchase order for the surface water treatment facility. Many of the components to be supolied in this purchase order are of a previous design, which will facilitate the manufacture and delivery of this equipment.
I.
It is currently scheduled for equipment to begin arriving at CPSES by August of 1979.
Final equipment arrival is scheduled for September, 1979.
Installation of the water treatment equipment should begin as soon as it arrives on, site. The majority of the components are on skid assemblies which will help minimize installation time. Detailed installation schedules will be developed based on finalized design information as it is received from the supplier.
After final installation of the equipment is completed, a period 4
of approximately two mont,hs will be required to integrate into the demineralized and potable water systems, which will have been operational. This period will also be used for systems checkout and startup.
