3 I. BRIDGE DESCRIPTION The Sisters Creek Bridge is a double leaf trunnion bascule drawbridge. The draw spans are raised and lowered by hydraulic pumps. The bridge is equipped with an emergency generating system, which will automatically engage if the public utility source is interrupted. The vertical clearance at the center of the draw span is 24 feet at mean high water and the horizontal clearance is 90 feet. Because of the major disruption to vehicular and marine traffic caused by malfunctions, it is very important for the bridge to be operated in strict accordance with this procedure. II. ENVIRONMENTAL REGULATIONS The Federal Water Pollution Control Act prohibits the discharge of oil or hazardous substance in such quantities as may be harmful (any oil that creates a sheen is deemed to be harmful) into or upon the navigable water or adjoining shorelines, river systems and tributaries extending upstream, 33 CFR (d) prohibits the use of any chemical including detergents, soap or solvents to disperse an oil sheen or slick. All report of oil or chemical discharges must be reported to the Department of Environmental Protection (DEP) by the most rapid available means. To assist in swift reporting of a spill, the bridge tender is to call (National Environmental Response Center), then immediately notify the FDOT Bridge Department. Failure to immediately report any discharge is a criminal violation as is any knowing or negligent discharge. III. STAFFING The bridge is staffed with one bridge tender per shift. The bridge tender duties and responsibilities are detailed in The FDOT District II Bridge Tending Manual, and also in this supplemental procedure, which provides detailed instructions on the operation of the bridge. IV. SPECIAL OPENING REGULATIONS There are no special opening regulations for this bridge. The bridge is to be opened on request Operating Supplement for the Sisters Creek Bridge

4 V. BRIDGE TENDER SHIFT CHANGE PROCEDURE At the beginning of each shift, any unresolved malfunctions, problems or other deficiencies that have been reported to the Florida Department of Transportation (FDOT) or any problems which the Bridge Tender is aware of shall again be noted in the Bridge Tender s Log. The entry shall briefly state the deficiency and the date and time it was originally reported. During the shift change, the seal on the bypass-key lockbox shall be checked and number verified to assure they are properly sealed, all safety equipment as described in this manual shall be checked to verify that it is in place and functioning, and the tenders will jointly review the Safety Equipment Checklist and the Bridge Tender Log. In order for the bridge tender to assume full responsibility for the bridge, which is the main purpose of the Shift Change Procedure, a fifteen (15) minute overlap of each shift will be necessary and required for the above functions to occur. This shall be accomplished by the oncoming bridge tender reporting to duty fifteen (15) minutes prior to the beginning of the scheduled shift. Both, the off-going and on-coming bridge tender, shall sign the Bridge Tender Log to document that the Shift Change Procedure has been adhered to. VI. BRIDGE OPERATION Listed below is the operating sequence for this bridge. The operator of the bridge must be at the controls when the span is in motion and not rely solely on the limit switches to stop the spans at the proper positions. Note that the bridge is equipped with an interlock system requiring a defined sequence of operations to be followed. The opening cycle is as follows: A. PLC (PROGRAMMABLE LOGIC CONTROL) MODE 1. Press the OPEN Button. The HORN button will flash to prompt the next step. 2. Notify any waiting vessels that the bridge is about to open by sounding one prolonged blast (5-6 sec) and one short blast (1 sec) of the horn. If the horn is inoperable, use the manual horn provided. If the horn is inoperable, upon completion of the opening, notify the FDOT; note the malfunction in the bridge tender log, and fill out a drawbridge malfunction report Operating Supplement for the Sisters Creek Bridge

5 The HORN button will stop flashing. The bridge traffic signals switch from green to yellow and the flashing yellow advance warning lights are turned on. The traffic signal indicator lights change to indicate the status of the traffic signal. After a five (5) second delay, the traffic signals switch from yellow to red. Fifteen (15) seconds after the traffic signal switches to red, the oncoming traffic gates D lights will flash to prompt the next step. If any of these switches fail to function, refer to the Malfunction Procedure section VII (A) and (B) for the control circuit switch, and section VII (C) for the traffic warning signal lights. CAUTION: DO NOT OPEN THE BRIDGE UNTIL THE SIGNALS ARE OPERATIONAL OR UNTIL FLAGMEN ARE PRESENT FOR TRAFFIC CONTROL. 3. After traffic has stopped and the gate lights are observed to be flashing, lower the on-coming traffic gates by depressing and holding the near ON COMING GATE LOWER button and far ON COMING GATE LOWER button until the gates are observed to be down. As the gates are being lowered the U and D lights are illuminated. When the gate is fully down the D light is illuminated continuously and the U light will flash indicating the gate could be raised. When all oncoming gates are fully down, the offgoing gate lights will flash to prompt the next step. If any of the gates fail to lower, refer to the Malfunction Procedure section VII (D). CAUTION: NEVER ATTEMPT TO OPEN THE DRAWSPAN WITHOUT THE TRAFFIC GATES BEING LOWERED OR FLAGMEN PRESENT TO CONTROL TRAFFIC. 4. After observing the span to assure that no vehicles or pedestrians are in the area, lower the off-going traffic gates by depressing the near gate off-going (NOG) LOWER button and the far gate off-going (FOG) LOWER button until the gates are observed to be down. If any of the gates fail to lower, refer to the Malfunction Procedure section VII (D) Operating Supplement for the Sisters Creek Bridge

16 VIII. EMERGENCY GENERATING SYSTEM A. OPERATION OF EMERGENCY GENERATING SYSTEM This drawbridge is equipped with an automatic cut-in power supply controlled by an Automatic Transfer Switch (ATS), which automatically starts the Emergency Generator and provides power to the bridge when the commercial power supply is disrupted. If power is lost and the emergency generating system will not function: Notify the FDOT Note the malfunction in the Bridge Tender Log Complete the Drawbridge Malfunction Report. NOTE: If this situation occurs during an opening request, the bridge cannot be raised. Notify any vessels awaiting an opening by using the manual horn provided, signaling with five (5) short blasts on the horn that the bridge cannot be raised. Notify appropriate authorities (FDOT, USCG, POLICE). B. EMERGENCY GENERATING SYSTEM CHECK The bridge tender shall make an entry into the Bridge Tender Log of the approximate time the generator runs and when it shuts down. If any opening occurs while the Emergency generator is running it should be noted in the Bridge Tender Log. If the generator does not start and run automatically, the bridge tender is to notify the FDOT. Bridge maintenance personnel will inspect and operate the emergency generator system in the following manner: 1. Check oil and water. 2. Start motor, using minimum throttle opening and minimum choke to keep motor operating at high idle, gradually increasing motor speed until operating speed is attained. 3. Allow motor to run for not less than 30 minutes before stopping. 4. Some emergency motor generator sets have automatic governors; therefore, it will not be possible to perform step (2) except by automatic means. 5. During the motor s operating period, determine whether there are oil or water leaks, or any other deficiencies existing Operating Supplement for the Sisters Creek Bridge

17 6. The bridge mechanisms shall be operated during one opening each month with power from the emergency generator to assure that emergency power openings can be made efficiently. This emergency power bridge opening should be made at the time of a regular emergency generator exercise. Record the result of this opening in the auxiliary power unit weekly checklist. 7. Check to insure that the fuel tank is at least half (1/2) full at all times and request fuel as needed. Request time is to be noted in the Auxiliary Power Unit Weekly Checklist. 8. An Auxiliary Power Unit Weekly Checklist is to be kept on the auxiliary engine. This inspection is to be performed every Monday at 11:00 a.m. or as close as possible. 9.
