Attachment 1 University of Florida Wastewater Treatment Plant and Lake Alice Recharge Well System l

The University of Florida wastewater treatment and discharge facilities include the treatment i plant. Lake Alice, and the recharge wells receiving drainage trom 12ke Alice. The location of these facilities is shown in Fipire 1. The facilities are used to treat and dispose of effluent from the UF campus (including etassrooms, offices, laboratories, student family housing apartments, student dormitories), Shands Hospital, J. Hillis Miller Medical Center complex, and Athletic Association facilities.

Wastewater Treatment Plant Descriotion The treatment system consists of two contact stabilization plants and a trickling filter plant operated in parallel. The present capacity of the treatment system is 3.1 MGD. Figure 2 is a diagram of the plant layout. Figure 3 is a schematic flow diagram for the facility.

Effluent from the treatment units is discharged into 12ke Alice. ,

Lake Alice Descriotion Lake Alice is located in the southwestern corner of the University of Florida Campus. The present 12ke Alice resulted from the damming of the outflow from a low marshy area, plus the addition of treated effluent and cooline water. The cooling water input is about 0.5 MGD.

Treated effluent input is about 1.83 MUD (average daily flow) with a peak daily flow of 2.33 million gallons.

Recharge Wells Two recharge wells were constructed in 1959 for the purpose of controlling the water level in Lake Alice, and preventing flooding of the adjoining road and portion of the wastewater treatment system.

New Wastewater Treatment Plant A new wastewater treatment plant is under construction and will replace the existing facility in a couple of years. The capacity of the new facility will remain the same as the current facility.

Attachment 2 RADIATION CONTROL TECHNIQUE #21 INSTRUCTIONS FOR UTILIZING, SAMPLING AND DISCHARGING LIQUID WASTE HOLDUP TANKS I. PURPOSE To establish a procedure for the utilization, circulation, sampling, and discharging of waste water contained in the UFTR/ Nuclear Sciences Center liquid waste holdup tanks.

II. PREREOUISITES A. Keys to: gate of the holdup tank facility, room 110 NSC, and the pump breaker.

B. Plumbing system diagram (attached)

C. 1 gallon container D. Rubber gloves III. NOTE Section 6.6.1, Operating Reports, Paragraph (5) of the UFTR Technical Specifications requires that each annual operating report shall include: "a summary of the nature and amount of radioactive effluents released or discharged to the environs beyond the effective control of the facility operators as determined at or before the point of such release or discharge (The summary shall include to the extent practicable an estimate of individual radionuclides present in the effluent. If the estimated average release after dilution or diffusion is less than 25% of the concentration allowed, a statement to this effect is sufficient.)".

IV. PROCEDURE A. Circulation of Tank Contents

1. Obtain keys to room 110 NSC, the pump breaker and the gate of the holdup tank facility.
2. Check the water level in the tanks by removing the small red plate (located on the north side of each pump housing) looking into tank and using a dip stick NOTE: The tank must be isolated and pumped before the water level rises to within three and one half feet of the top of the tank.
p. 1 of 6 6/88
3. To circulate the contents of a tank, close either valve E2 or valve W2 (discharge valves to sewage system). Open valve El or valve W1 depending on which tank is to be circulated. The post indicator valve for the tank to be circulated (A for the East, B for the West) should be SHUT and the opposing indicator valve must be OPEN.
4. Proceed to room 110 NSC and locate the holding tank pump breaker box. Position the pump main circuit breakers in the ON position. Turn the pump selector switch to WEST or EAST depending on which tank is to be circulated. The green indicator lamp and the red breaker lamp should '

light. If the green indicator lamp does not light, verify that the main circuit breaker is ON, then push the RESET button (on the pump controller to the left and below the pump selector switch).

5. Allow the pump to operate until the equivalent of two tank volumes has circulated (about 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />).

B. Sampling Tank Contents I

1. After proper circulation, a sample can be collected using a 1 gallon sample container. i Fill the sample container by opening the sampling valve (circulating pump running) located near valve W1 or El. Flush the sampling line by collecting 1 gallon of liquid. (This liquid should be poured back into the tank.) After the  ;

sample (1 gallon) has been obtained, the pump selector switch can be turned off.

2. Prepare the sample for analysis in accordance with Radiation Control Technique #7. Analysis of the sample shall be performed using Radiation Control Technique #8.  ;

C. Adding Dilution Water

1. If tank is not full, remove tank cover plate and add dilution water to bring tank contents ,

up to about three and one half feet of the top of the tank.

2. Record dilution water volume on the Release Authorization form. ,

of the MPC valu2s before aligning the system to pump into the campus sewage system.

2. Assure that the estimated average release concentration is less than 25% of the concentration allowed or that an estimate of individual radionuclides present in the tank contents has been documented.
3. Obtain Radiation Control Officer and UFTR Director or Reactor Manager approval prior to emptying tank.
4. To empty the west tank and reroute flow to the cast tank, open valve A by turning the wrench handle until indicator reads OPEN, shut valve B by turning handle until indicator reads SHUT.

Open valve W2, close W1. Close valve E2, open l

valve El, turn on the west pump as instructed in III B.4 of this procedure. The pumping of the west tank is automatically terminated when the tank is empty.

5. Return pump controller switch to the OFF position and lock OPEN pump breakers.

E. Emptying East Tank and Rerouting Flow to West Tank

1. See section IV: steps E.1, E.2., and E.3.
2. To empty the east tank and reroute flow to the west tank, open valve B by turning the wrench handle until indicator reads OPEN, shut valve A by turning handle until indicator reads SHUT.

Open valve E2, close valve El. Close valve W2, open valve W1. Turn on the east pump as instructed in IV B.4. The pumping of the east tank is automatically terminated when the tank is empty.

Radionuclide MPC Action I2 vel uCi/ml uCi/mi H-3 1.0E-01 1.0E-03 C-14 2.0E-02 2.0E-04 P-32 5.0E-04 5.0E-06 S-35 2.0E-03 2.0E-05 Ca-45 3.0E-04 3.0E-06 Cr-51 5.0E-02 5.0E-04 Co-57 2.0E-02 2.0E-04 I-125 4.0E-05 4.0E-07 I-131 6.0E-05 6.0E-07 gross alpha / beta 4.0E-07 4.0E-09 The MPC used is applicable to sanitary sewage system disposal.

3. When sam ale analysis indicates a radionuclide activity at or greater than the action evel the following actions will be taken:
a. Discontinue discharge of radioactivity into the sanitary sewage system. Since the Radiation Control Depanment will be responsible for introducing radioactivity mto the sanitary sewage system, this will be immediately enforceable.
b. Obtain additional environmental samples and perform analyses to verify the initial results of radionuclide activity at or greater than the action level.
c. Determine if radioactivity is due to individuals undergoing medical diagnosis or therapy. For example, I-131 is used in medical therapy.
d. If additional sample analysir does not support the initial results or if sample radioactivity is due to medical diagnosis or therapy, discharge of radioactivity may continue.
