PURPOSE To provide a method for personnel to sample, test and treat plant potable water systems in order to protect the health of Vermont Yankee employees, contractors and visitors.

There are no Technical Specifications applicable to potable water systems.

DISCUSSION Potable water is supplied to various locations at the plant site from four drilled wells.

The West Well supplies the Main Building complex as well as Gate House 1 & 2, South Warehouse and the Governor Hunt House. The COB well supplies the Containment Office Building. The Southwest Well provides a secondary/backup source of water for buildings normally supplied by the West Well. The NewEngineering Office Building Well supplies water to that building only. Specific information on each of the four plant wells is given in Table 1.

The State of Vermont has classified the Vermont Yankee Plant as having three non-transient, non-community public water systems. The Main Plant System, supplied by the West/Southwest Wells, has the State Identification number WSID-8332. The COB System, supplied by the COB well, has the State Identification number WSID-20559. The New Engineering Office Building System has the State Identification number WSID-20738.

However, all three of these systems are considered Class II by the State. At least one person at Vermont Yankee must be certified by the State of Vermont as a Class II public water system operator.

Water samples must be taken on a routine basis from drinking water outlets supplied by each of the three plant potable water systems to ensure that potable water is safe to drink and meets the State and Federal drinking water requirements. Water samples are also taken quarterly from each potable water systemper OP 4605 and analyzed for the presence of radionuclides.

Annually the State of Vermont Water Supply Division personnel will provide Vermont Yankee with a schedule of what tests in addition to coliform are to be performed (if any).

If analytical data indicates that one of the potable water systems may contain a contaminant that exceeds one of the Maximum Concentration Limits (MCLs) listed in the Vermont Water Supply Rule - Chapter 21, the drinking water outlets supplied by that system may be required to be posted "DO NOT DRINK THE WATER" and the Vermont Water Supply Division must be notified within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

50.59 Applicability Determination previously completed and showed 50.59 screening is not required.

RP 2616 Rev. 3 Page 3 of 15

Laboratories that perform tests on Vermont Yankee potable water samples to meet State compliance monitoring requirements must be listed on the "Table of Laboratories Acceptable to the Vermont Water Supply Division for Compliance Monitoring"; otherwise, the analytical results will not be acceptable for compliance monitoring purposes. All samples that are analyzed by contractor laboratories must be transported with a completed Chain of Custody Form.

PROCEDURE I

1. Sampling for Coliform Bacteria (WSR 6.3 and 40 CFR 141.21)

NOTE During each quarter of the year a sample of potable water must be taken from an outlet supplied by each of the potable water systems and analyzed for the presence of coliform bacteria per the Water Supply Rule. Sample locations should be varied each quarter per the bacteriological sampling plan (see Figure 1).

a. Proceed to one of the potable water outlets to be sampled.

b. Remove the faucet strainer/aerator using a clean paper towel to prevent finger contact.

c. Sanitize the outlet area of the faucet with isopropyl alcohol or germicidal cloth.

I d. Turn the faucet on and let the water run at full flow for a total of 8-10 minutes before taking a sample. If sampling from a mixing faucet, run the hot water for 2 minutes, then the cold water for 6-8 minutes.

e. Note purge start time on VYRPF 2616.01 form.

f. Reduce the flow from the faucet and fill the sample bottle to slightly above the 100 ml line. (Coliform test requires 100 ml of sample)

I 5. Chlorination of Plant Wells and Water System Components NOTE It may be necessary to chlorinate one or more of the plant wells if potable water analysis results indicate that coliform bacteria are present or there was a maintenance activity which would introduce coliform bacteria into the system.

I CAUTION I Potable water outlets supplied by the well to be chlorinated must be posted "do not drink the water".

I a. Issue a Work Order to Maintenance Department to chlorinate the well.

b. Determine total depth of well to be treated (Table 1).

RP 2616 Rev. 3 Page 11 of 15

c. Calculate the standing water column.

1) Using Solinst water level indicator determine depth to groundwater in well in feet.

2) Use following calculation to determine standing water column in well:

a) Total depth of well (feet) - depth to groundwater (feet) = standing water column (feet).

d. Calculate storage capacity.

1) Use the following information to determine storage capacity in gallons per foot of water column:

Storage capacity in gallons per foot of water Diameter of well casing in inches column 6 1.47 8 2.62

e. Calculate volume of water in gallons.

1) Standing water column (feet)* 1.47 or 2.62 = gallons requiring disinfection.

f. Calculate the disinfectant dose and contact time required to shock 100 gallons using the following information:

Chlorine Dose Required Contact Time If using Bleach 5.25%, If using, HTH (solid) add 65% (pool shock), add 50 mg/L 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> 1 pint 1 ounce or 2 teaspoons 100 mg[L 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> 1 quart 2 ounces or 4 teaspoons 200 mg/L 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> 2 quarts 4 ounces or 8 teaspoons RP 2616 Rev. 3 Page 12 of 15

NOTE For wells with a water column of more than 200 feet or a production 1' that exceeds the submersible output, add a combination of HTH and bleach. Use enough bleach to disinfect the first 200 feet of water column and use HTH on the remainder of the column. Crushing the HTH tablets will give better mixing potential with the water column.

g. Chlorinate well by pouring the appropriate volume of disinfectant down the well casing.

h. Instruct Maintenance to recirculate the well until disinfectant can be smelled and the casing has been adequately washed down.

NOTE Recirculation of the West well may not be possible due to its distance from the plant..

i. Allow shocked water to remain isolated for the required contact time.

j. Flush the chlorinated well by opening applicable potable water outlets.

CAUTION Prior flushing activities, water meter readings should be recorded per RP 4615 to ensure proper accountability during reporting to the VTDEC.

k. Following flushing, Chemistry personnel will take a sample to ensure that the chlorine residual is <0.5 ppm.

1. Perform coliform bacteria sampling per Section 1.

m. Remove !'Do Not Drink the Water" signs as instructed by a Chemistry Class II or III Public Water System Operator.

RP 2616 Rev. 3 Page 13 of 15
