This will also be a time for you to learn and demonstrate the required skills involved with your job description. You will also be expected to become familiar with other relevant information about the rules and regulations of both the City and the department. Your supervisor will work closely with you on all aspects of your training, understanding and responsibilities during this probationary period. We encourage you to get to know your fellow co-workers and supervisors quickly as this tends to help you succeed in your department. The following list of objectives will be measured during this probationary period and you will be evaluated at the probationary end on your understanding and demonstrating abilities of these objectives. In order for your supervisor to measure your progress, you will be given a 90 -day progress evaluation. At this time, you should be able to demonstrate your knowledge, understanding, and operation of: 1. The City of Cape Canaveral's Employee Policy and Procedures 2. The Union agreement. 3. How to calibrate CL2, pH, NTU & D.O. meters. 4. The location of all plant sample points and the proper way to collect process samples. 5.

Once the samples have been collected, rinse each bottle with non -potable water before bringing the samples into the lab. for testing. Procedure Note:- To obtain a well mixed sample, it is important to invert the bottles gently several times immediately prior to pouring. Spin Test :- Fill two 15ml. centrifuge tubes with the AW sample and 2 with the RAS sample. Wipe the outside of the tubes with a paper towel and place them in the centrifuge. Settlometer:- Fill the settlometer to the two liter mark with well mixed sample. Using the stirring paddle mix the sample carefully with a back and forward motion. Place a 5 minute and 30 minute timer in the automatic timer. Start the centrifuge at speed 6 on the dial. After the 5 minute alarm stop the centrifuge and read the volume of solids in the settlometer. Read the volume of settled solids in the centrifuge tubes. Record all readings on the bench sheet (see attached) While waiting for the 30 minute buzzer, wash the sample bottles and centrifuge tubes. When the 30 minute alarm sounds, read the volume of settled solids in the settlometer and record on the bench sheet. After finishing the settlometer test, wash the container and wash down the surfaces with 70% Isopropyl Alcohol. All equipment is to be dried and put away in the appropriate place at the conclusion of the tasks. 7 SOP FOR TOTAL SUSPENDED SOLIDS (T.S.S.)

Used Petri dishes are placed in the biohazard bin to be autoclaved prior to disposal. Procedure:- A) Collect sample from the Wet Well in a 1liter Nalgene bottle that has been wrapped in instrument wrap, sealed with indicator tape and autoclaved. B) Return to lab. Pour sample into whirlpak bag(s). C) Open Whirlpak bag by pulling the tabs outwards. Fill 2 "Whirl Pak" bags to the 4oz. mark with sample. Close bags by bringing top edges together. Seal the bag by twirling it around the closure several times and turn wire tab inwards toward the folded edge. Sample must be placed in fridge, and allowed to sit with the Sodium Thiosulfate tablet for at least 15 min. before analysis. Begin analysis within 6 hours of sampling. E) Assemble the sterile filter apparatus using aseptic techniques, making sure that none of the contact surfaces becomes contaminated, and attach to vacuum pump. F) Prepare the Petri dishes by saturating each pad with the contents of an MF -C broth ampule. Always place the Petri dish lids open side up on the counter and do not reach over open Petri dishes. G) Label each sterile Petri dish with the sample ID, date and analyst's initials. Samples are uniquely identified on the bench sheet by ID # (assigned by the lab) , location and are run in the following order: - Blank Tank. Tank Dup River,lf applicable River Dup.

Place pH probe into #7 buffer solution and then push STD button, and then press the clear button the erase the last calibration. Press the standard button again on meter, wait until stable reading is displayed (a beep will follow stable reading). You will need to record both readings before the beep so watch screen carefully. (One reading is a check and the other is the calibration reading). If you see the standard prompt flashing then you will have to push standard button again to move forward with the calibration process. Record your results in the log book. 3. Remove pH probe from buffer solution and rinse with D.I water, place probe into the #4 buffer solution and push standard button. Record your readings in log book. 4. Rinse pH probe with D.I water and place into #10 buffer solution. Press standard button and follow prompts for calibration. After last calibration, you will need to record temp and slope % into log book. Acceptable slope range is 90-105 %.

Log onto the Alarm Page on the computer in the motor control room. 2. Click on Acknowledge Alarm Log. 3. Click on Reject Reset. 4. Push the EVA Reset Reuse Tank button on the grey cabinet in the motor control room. 5. Using the controller by the reject tank, switch to Manual and press the close button. After the MOV valve closes switch back from Manual to Remote mode. 6. Enter all the information into the Reject Log Book located in the motor control room. 17 Emergency manual aeration start In motor control: On the panel and #01 & and #2 Switch the key from remote to manual. Turn switch from off to high. In blower room: On the and #1 & and #2 V.F.D. panel move switch from auto to hand. Use dial on keypad to set aeration speed- 50 to 60hz.
