c. First aid kits are for emergency use only and shall be refilled after use.

E. JURISDICTION

1. Primary jurisdiction to regulate drawbridges over the navigable waters of the United States is vested in the United States Coast Guard. The regulations are presented in the Code of Federal Regulations, Title 33 -Navigation and Navigable Waters, hereinafter referred to as CFR 33. Such bridges owned and operated by Pinellas County have been constructed and are maintained and operated by permit from the United States Coast Guard. All rules for Pinellas County to operate the bridge shall be issued by the County.

2. If any person knowingly fails to comply with any regulation or rule issued or order given under the provisions of CFR 33, or knowingly obstructs or interferes with the exercise of any power conferred by CFR 33, he may be punished by imprisonment for not more than ten (10) years and may, at the discretion of the court, be fined not more than $10,000.00. Pinellas County shall train and educate his bridge tenders accordingly. The contractor will be responsible for the conduct of its employees.

F. SIGNALS

1. GENERAL

a. The operator of each vessel requesting a drawbridge to open shall signal the bridge tender and the bridge tender shall acknowledge that signal. The vessel operator shall repeat the signal until the bridge tender has acknowledged in some manner. The vessel shall not approach the bridge until he received the bridge tender's acknowledgement.

Exhibit A - Page 4

b. The authorized signal devices and order of preference to be used to request an opening and to acknowledge a request shall be communication by radio telephone, sound signals, or visual signals. Whatever signals are used, they must be sufficient to alert the person being signaled.

c. All acknowledging signals given by the bridge tender shall follow the requesting signal by no more than 30 seconds.

d. Common sense is to be used if a boat does not properly signal. The boat should not be sitting there while the bridge tender refuses to open, waiting for the proper signal.

2. VESSEL SIGNALS FOR BRIDGE OPENING REQUEST

a. Communication by Radio telephone.

Communication by radio telephone may be used to request the bridge opening, however, when the contact cannot be initiated or maintained, sound or visual signals shall be used. Channel 16 shall always be monitored but should not be used for communications, use the operating channel assigned to the bridge instead. If the tender receives an opening request on channel 16, he should briefly communicate to the requesting party to switch to the bridge operating channel (9) to continue the communication.

b. Sound Signals.

Sound signals shall be made by whistle, horn, megaphone, hailer or other device capable of producing the prescribed signals. A "prolonged blast" is 4 to 6 seconds in duration; a "short blast" is about 1 second duration. The sound signal to request the opening of a drawbridge is one prolonged blast followed (within 3 seconds) by one short blast. During scheduled closure periods, a vessel for which the draw is required to open (e.g., a public vessel of the U.S., vessel in tow or a vessel in distress), identifies its special status and requests draw opening by sounding five (5) short blasts in rapid succession.

c. Visual Signals.

Visual signaling to request the opening of a drawbridge is accomplished by vertically raising and lowering a white flag or vertically raising and lowering a white, amber or green light.

3. BRIDGE TENDER'S RESPONSE SIGNALS

a. Communication by Radio telephone. If the request for bridge opening has been made by radio telephone, the response will normally be completed by this method. In the event contact cannot be maintained, sound or visual signals will be used. Channel 16 shall always be monitored but should not be used for communications, use the bridge operating channel (9) instead.

b. Sound Signals

Sound signals shall be made by activating the horn mounted on the bridge tender house. When the bridge can be opened immediately, the sound signal to acknowledge a request to open the bridge is one prolonged blast followed by one short blast (as defined above). When the bridge cannot be opened immediately or is open and must be closed promptly, the sound signal to acknowledge a request to open the bridge is five short blasts sounded in rapid succession. The signal shall be repeated until acknowledged in some manner by the requesting vessel. If the vessel does not continue its approach, this can be interpreted by the bridge tender as the vessel operator's acknowledgement and the bridge tender can cease his signal.

c. Visual Signals

When the bridge can be opened immediately, the visual signal to acknowledge a request to open the bridge is one of the following:

1) A white flag raised or lowered vertically or

2) A white, amber or green light raised and lowered vertically or

3) A fixed or flashing white, amber or green light or lights.

When the draw cannot be opened immediately or is open and must be closed promptly, the visual signal to acknowledge a request to open the bridge is one of the following:

Exhibit A - Page 5

1) A red flag or red light swung back and forth horizontally in full sight of the vessel or

2) A fixed or flashing red light or lights.

The signal shall be repeated until acknowledged in some manner by the requesting vessel. If the vessel does not continue its approach, this can be interpreted by the bridge tender as the vessel operator's acknowledgment and the bridge tender can cease his signal.

d. Visual Sight

Common sense is to be used if a boat does not properly signal. The boat should not be sitting there while the Tender refuses to open, waiting for the proper signal.

G. NATURAL DISASTERS

1. Federal regulations authorized drawbridges to remain closed during a natural disaster such as a hurricane unless the Coast Guard specifically directs otherwise. The regulations do not permit closure in anticipation of a disaster without prior Coast Guard approval.

2. Authorities desiring to temporarily cease or restrict drawbridge openings to facilitate evacuation of land traffic before the arrival of a hurricane must obtain authorization from Commander, Seventh Coast Guard District.

3. This must be done by County Representative ONLY!!!! Call (305) 536-6546 between 7:30 a.m. and 4:00 p.m., Monday through Friday. At all other times call the Coast Guard Duty Officer at (305) 536- 5611. The Duty Officer will relay the request and furnish a response within minutes. Temporary closures are approved on a case by case basis and only if operation of the bridge impedes evacuation.

Specific regulations may exist for certain bridges which require opening on signal during periods of storm warning or alerts.

4. High winds may make a drawbridge inoperable or subject it to damage. Drawbridges are authorized to remain closed while experiencing steady winds of 34 knots (39 mph) or more if the Pinellas County has determined that closure is required to prevent damage to the bridge. When this condition exists, notations must be made in the DAILY BRIDGE LOG, including wind speed and direction. Requests to close drawbridges at wind speeds less than 34 knots (39 mph) to prevent damage will be considered by the Coast Guard. Such requests should be accompanied by an engineering analysis showing the maximum wind the bridge could be expected to experience without damage while in an opened or partially opened position. Closure of a bridge because of high winds should be reported to the Coast Guard immediately as well as the Bridge Supervisor and noted in DAILY BRIDGE LOG.

H. SPECIAL REGULATIONS

1. In the absence of specific regulations specifying otherwise, a drawbridge is required to open promptly on signal. Notwithstanding such approved schedules; when a bridge tender is informed by a reliable source than an emergency vehicle is due to cross the draw or if he sees or hears an emergency vehicle approaching, the bridge tender shall take all reasonable measures to have the draw closed at the time the emergency vehicle arrives at the bridge. The bridge tender shall give appropriate signals to any approaching vessels under the circumstances.

2. Except as provided by particular bridge opening schedules, drawbridges shall be opened promptly and fully for the passage of vessels when a request to open has been given in accordance with the signaling procedures established. Under no circumstances is the bridge tender to question the vessel operator as to his right for a bridge opening based on the height of his vessel, the bridge tender shall, in all cases, open the draw span if the pilot signals for a bridge opening. If a bridge tender is required to open a drawbridge for a vessel because of non-structural fixture on that vessel, which in his opinion, is not essential to navigation or which is easily lowered, he is to complete the BRIDGE TENDER'S REPORT ON UNNECESSARY BRIDGE OPENING (Form Appendix B-2) and submit it to his supervisor.

3. The County may obtain permission from the United States Coast Guard to temporarily alter the schedule or to temporarily close a bridge. When permission is obtained, the supervisor will inform the bridge tender and the bridge tender is required to comply with the temporary conditions.

Exhibit A - Page 6

I. INSTRUCTION FOR BRIDGE MECHANISM OPERATION

The following general procedures shall be followed by bridge tenders in operating the drawbridge spans owned by Pinellas County. All of the bridges in the County have electrical equipment interlocked so that a definite sequencing of operation is necessary in order to operate the spans.

Specific instructions on specific bridge operation are in Section I-6.

1. General Procedure

a. Return signal to vessel for opening. Pinellas County requires an audible signal before any opening, which will also alert maintenance personnel, pedestrians, fishermen, etc.

b. Initiate opening sequence.

1) Check the roadway for vehicles or pedestrians approaching so closely as to be endangered by lowering the traffic gates.

2) Turn ON the highway traffic bell signals and warning lights and/or traffic lights to stop oncoming traffic.

3) Recheck the roadway for vehicles or pedestrians approaching so closely as to be endangered by lowering the traffic gates.

4) Lower the traffic safety gates to keep the traffic from advancing towards the draw span.

Oncoming gates shall be lowered first.

5) Insure that pedestrians are clear of the opening span(s), (Dunedin Bridge tenders must physically cross the bridge span to the south side and check the trail to insure that pedestrians are clear of the opening span), then release span locks.

6) Then release the motor brakes.

7) Operate the controller to open the span(s) to its fully open position using extreme care in the final opening operation to prevent any damage to the bridge.

8) Set motor brakes.

c. As the vessel passes, observe and log the name or number and type of vessel, direction of travel, date and time of passage, and initial entry on the MONTHLY REPORT OF DRAWBRIDGE OPENINGS (Form Appendix B-10).

d. After the vessel has cleared the bridge, check to make sure no other vessels are approaching. If none are approaching, signal for bridge closure.

e. Initiate closing sequence.

1) Release motor brakes.

2) Operate the controller to close the span(s) using extreme care in the final closing operation to prevent any damage to the bridge.

3) Operate the lock motors to close the span locks.

4) Set motor brakes.

5) Raise the traffic safety gates, the oncoming gates shall be opened last, stop traffic bells and warning signals, switch traffic lights to green and permit highway traffic to precede.

f. In the event that the bridge fails to operate, you are to note it in the DAILY BRIDGE LOG (form

Appendix B-11). In all cases, first advise the bridge supervisor of the problem by phone.

g. All bypass switches are provided with seals. In the event it becomes necessary to utilize the bypasses, first Notify your supervisor, by phone, of the problem, for remedy and approval to break the seal must be given by Pinellas County Representative. A notation shall be made on the DAILY BRIDGE LOG indicating the reasons and the person authorizing by pass use. Failure to do so will result in disciplinary action. The bridge supervisor shall be notified immediately of any broken bypass seals. See bypass procedure below.

Exhibit A - Page 7

2. Bypass Procedure

a. If malfunction occurs call Pinellas County Roadway Maintenance, 464-8900. There is a person answering this number 24 hours a day. If you are unable to reach someone leave a message and call the Bridge Emergency Number 727-580-6273 or 727-580-2391.

b. DO NOT cut bypass seal without permission from Pinellas County Bridge Tender Supervisor.

c. When authorization has been given to cut bypass seal you will:

1) Log it on your DAILY BRIDGE LOG, date & time, seal was cut and why it had to be cut and the name of the person authorizing it to be cut.

2) When the problem has been corrected by Pinellas County and the seal has been replaced, log it on your DAILY BRIDGE LOG, date and time, bypass was resealed and who performed the repair.

3. Safety Interlock Bypass Selector Switches

CAUTION: Extreme care should be exercised when utilizing these switches, as serious damage to machinery and personnel may result.

a. There are three safety interlock bypass switches for the bridge leafs. The purpose of these switches are to enable qualified Pinellas County maintenance personnel the ability to bypass the limit switches which indicate the position of various mechanical parts in case of their failure as is necessary in an emergency situation.

1) GATE BYPASS When this switch is in the ON position; all safety interlocks for the traffic gates are bypassed. The span locks may be pulled without the traffic gates being fully lowered. The traffic lights may be turned green without the traffic gates being fully raised.

2) SPAN LOCK BYPASS When this switch is in the ON position; all safety interlocks for the span locks are bypassed. The bridge leaves may be raised or lowered without the span locks being fully pulled. The traffic gates may be raised without the span locks being fully driven.

3) SPAN BYPASS When this switch is in the ON position; all safety interlocks for the bridge leaves are bypassed. The span locks may be driven without the bridge leaves being fully lowered. The navigation lights may be turned green without the bridge leaves being fully raised.

4. Auxiliary Power Unit Procedure

a. Automatic Auxiliary Power Unit Procedure In case of an electrical power failure, an emergency generator is available to provide back-up power failure; an emergency generator is available to provide back-up power. Generator power is selected by turning the generator switch located on the control console to the TEST position. If it is desired to run the generator only, without having generator power supplied, the generator switch may be turned to the RUN position. In all other instances, the generator switch should be in the AUTOMATIC position.

5. Navigation Traffic Lights Selector Switch

a. The navigation light selector switch is located on the CONTROL CONSOLE.

It has three positions which may be selected. When MANUAL MODE is selected, the navigation lights remain on and operational at all times. When AUTOMATIC MODE is selected, the navigation lights will turn on and operate during night hours only. When OFF is selected, the navigation lights remain off and in operational.

CAUTION: The operator must inspect the bridge before lowering the far off going traffic gate to be sure that there are no vehicles still present on the bridge.

7) The far off going traffic gate may then be lowered by depressing the FAR OFF GOING TRAFFIC GATE LOWER push-button. As in the operation of the NEAR ONCOMING TRAFFIC GATE RAISE push-button, this push-button must be held depressed in order for motion to occur. Release of this push-button will stop the gate from moving.

As the far off going traffic gate is being lowered, the FAR OFF GOING TRAFFIC GATE RAISED indicator light will go out. Once the far off going traffic gate is fully lowered, the FAR OFF GOING TRAFFIC GATE LOWERED indicator light will illuminate.

Exhibit A - Page 10

8) The normal sequence of operation of the traffic gates may be suspended at any time by releasing the appropriate TRAFFIC GATE LOWER push-button. The sequence of operation may then be resumed by pulling out the appropriate TRAFFIC GATE LOWER push-button, or the sequence may be aborted by pulling out the appropriate TRAFFIC GATE RAISE push-button.

9) Once all of the traffic gates are lowered, the span locks will be enabled. At this time the tender must cross to the south side of the bridge to check the trail to insure pedestrians are clear of the opening spans.

10) The span locks may then be retracted by pulling out the SPAN LOCKS PULL push-button. As the span locks are being retracted, the SPAN LOCKS DRIVEN indicator light will go out. Once the span locks are fully retracted, the SPAN LOCKS PULLED indicator light will illuminate, and the raise sequence is enabled.

11) The normal sequence of operation of the span locks may be suspended at any time by pulling out the STOP push-button. The sequence of operation may then be resumed by pulling out the SPAN LOCKS PULL push-button, or the sequence may be aborted by pulling out the SPAN LOCKS DRIVE push-button.

12) Prior to raising the bridge, you may sound the horn again by depressing the HORN push-button one time long and one time short. Each bridge leaf may then be raised by turning the corresponding LEVER, near span is turned clockwise and far span is turned counter clockwise. The LEVER has six maintained positions which correspond to six various speeds.

The farther the LEVER is turned, the faster the bridge leaf will rise.

13) While a bridge leaf is in motion, the BRAKE SET indicator light will go out, and the BRAKE RELEASE indicator light will illuminate, indicating that the brake motor is running and has released the bridge leaf motor. When the bridge leaf motor stops, the brake motor stops, the BRAKE RELEASE indicator light will go out, and the BRAKE SET indicator light will illuminate.

14) As a bridge leaf is being raised, the FULLY CLOSED indicator light will immediately go out.

Once a bridge leaf has risen far enough to break contact with its respective nearly closed limit switch, the NEARLY CLOSED indicator light will go out. Once a bridge leaf has risen far enough to make contact with its respective nearly open limit switch, the NEARLY OPEN indicator light will illuminate, and the bridge leaf will automatically rise at a slower speed. The bridge leaf will continue at that slower speed until it makes contact with its respective fully open limit switch, at which time the FULLY OPEN indicator light will also illuminate, and the bridge leaf will automatically stop.

15) The raising sequence of either of the bridge leaves may be suspended at any time by slowly turning the corresponding LEVER, near span is turned counter clockwise and far span is turned clockwise, to its slow speed position.

16) When the LEVER is slowly turned to its slow speed position, the bridge leaf will decelerate to a controlled stop. The raise sequence may then be resumed by pulling the LEVER, near span is turned clockwise and far span is turned counter clockwise or the sequence may be aborted (the bridge leaf lowered) by turning the LEVER near span is turned counter clockwise and far span is turned clockwise. The farther the LEVER is turned, the faster the bridge leaf will lower.

17) While the bridge leaves are in motion the LEVER may be returned to its neutral position, to stop the leafs abruptly. This will cause excessive wear and damage to the mechanical parts, however, and should therefore be used only in emergency situations. The raise sequence of operation may then be resumed by turning the LEVER, near span is turned clockwise and far span is turned counter clockwise or the sequence may be aborted (the bridge leaf lowered) by turning the LEVER near span is turned counter clockwise and far span is turned clockwise.

The farther the LEVER is turned, the faster the bridge leaf will lower.

18) While the bridge leaves are in motion, the CONTROL POWER OFF push-button may be depressed, to stop the leaves abruptly. This will cause excessive wear and damage to the mechanical parts, however, and should therefore be used only in emergency situations.

The raise sequence of the operation may then be resumed by turning the LEVER back to its neutral position, pulling out the CONTROL POWER ON push-button and turning the LEVER, near span is turned clockwise and far span is turned counter clockwise, or the sequence may

Exhibit A - Page 11 be aborted (the bridge leaf lowered) by turning the LEVER, near span is turned counter clockwise and far span is turned clockwise. The farther the LEVER is turned, the faster the bridge leaf will lower.

19) Once both bridge leaves are in their fully open position, the navigation lights will automatically turn from red to green, providing the NAVIGATION LIGHTS SELECTOR SWITCH is turned to the ON position.

Lower Sequence

1) Prior to lowering the bridge, the horn should be sounded by pulling out the HORN push-button five short consecutive times. You should also verify all boat traffic has cleared the spans.

2) Each bridge leaf may then be lowered by turning the corresponding LEVER, near span is turned counter clockwise and far span is turned clockwise. The LEVER has six maintained positions which correspond to six various speeds. The farther the LEVER is turned, near span is turned counter clockwise and far span is turned clockwise, the faster the bridge leaf will lower.

3) While a bridge leaf is in motion, the BRAKE SET indicator light will go out, and the BRAKE RELEASE indicator light will illuminate, indicating the brake motor is running and has released the bridge leaf motor. When the bridge leaf motor stops, the brake motor stops, the BRAKE RELEASE indicator light will go out, and the BRAKE SET indicator light will illuminate.

4) As a bridge leaf is being lowered, the FULLY OPEN indicator light will immediately go out.

Once a bridge leaf has lowered far enough to break contact with its respective nearly open limit switch, the NEARLY OPEN indicator light will go out. Once a bridge leaf has lowered far enough to make contact with its respective nearly closed limit switch, the NEARLY CLOSED indicator light will illuminate, and the bridge leaf will automatically lower at the slower speed.

The bridge leaf will continue at that slower speed until it makes contact with its respective fully closed limit switch, at which time the FULLY CLOSED indicator light will illuminate, and the bridge leaf will automatically stop.

5) The lowering sequence of either of the bridge leaves may be suspended at any time by slowly pushing the corresponding LEVER, near span is turned counter clockwise and far span is turned clockwise, back to its slow speed position.

6) When the LEVER is slowly turned to its slow speed position, the bridge leaf will decelerate to a controlled stop. The lower sequence may then be resumed by turning the LEVER, the near span is turned counter clockwise and the far span is turned clockwise, or the sequence may be aborted (the bridge leaf raised) by turning the LEVER, near span is turned clockwise and far span is turned counter clockwise. The farther the LEVER is turned, the faster the bridge leaf will rise.

7) While the bridge leaves are in motion the LEVER may be returned to its neutral position, to stop the leaves abruptly. This will cause excessive wear and damage to the mechanical parts, however, and should therefore be used only in emergency situations. The lower sequence of operation may then be resumed by turning the LEVER, near span is turned counter clockwise and far span is turned counter clockwise, or the sequence may be aborted (the bridge leaf raised) by turning the LEVER near span is turned clockwise and far span is turned counter clockwise. The farther the LEVER is turned, the faster the bridge leaf will rise.

8) While the bridge leaves are in motion, the CONTROL POWER OFF push-button may be depressed to stop the leaves abruptly. This will cause excessive wear and damage to the mechanical parts, however, and should therefore be used only in emergency situations.

The lower sequence of operation may then be resumed by turning the LEVER back to its neutral position, pulling out the CONTROL POWER ON push-button and turning the LEVER near span is turned counter clockwise and far span is turned counter clockwise or the sequence may be aborted (the bridge leaf raised) by turning the LEVER, near span is turned clockwise and far span is turned counter clockwise. The farther the LEVER is turned, the faster the bridge leaf will rise.

CAUTION: Care should be taken in the special case of suspending the bridge lower sequence when the bridge leaf is within 5 degrees of being fully closed. If the FULLY CLOSED LIMIT SWITCH is improperly set, the switch may trip prematurely, and prevent

Exhibit A - Page 12 the bridge from fully closing. Should this happen, the bridge should be raised again until it is at least 15 degrees inclined, then lowered to set the leaves properly, and the following step followed.

9) Once both bridge leaves have fully closed, the bridge leaves may be seated by pulling out and holding in the SEAT push-button. As a leaf is being seated, the BRAKE SET indicator light will go out, the BRAKE RELEASE indicator light will illuminate, indicating the brake motor is running and has released the bridge leaf motor. The bridge leaf motor will then slowly lower the bridge leaf down into a fully seated position. Release of the SEAT push-button will stop the bridge leaf motor and brake motor. Once the brake motor stops, the BRAKE RELEASE indicator light will go out, and the BRAKE SET indicator light will illuminate.

10) Once both bridge leaves have fully closed, and both brakes set, the span locks will be enabled. The span locks may then be extended by pulling out the SPAN LOCKS DRIVE push-button. As the span locks are being driven, the SPAN LOCKS PULLED indicator light will go out. Once the span locks are fully driven, the SPAN LOCKS DRIVEN indicator light will illuminate, and the off going traffic gates are enabled.

11) The normal sequence of operation of the span locks may be suspended at any time by depressing the STOP push-button. The sequence of operation may then be resumed by depressing the SPAN LOCKS DRIVE push-button, or the sequence may be aborted by pulling out the SPAN LOCKS PULL push-button.

12) The far off going traffic gate may then be raised by depressing the FAR OFF GOING TRAFFIC GATE RAISE push-button. As the far off going traffic gate is being raised, the FAR OFF GOING TRAFFIC GATE LOWERED indicator light will go out. Once the far off going traffic gate raised, the FAR OFF GOING TRAFFIC GATE RAISED indicator light will illuminate, and the near oncoming traffic gate will be enabled.

13) The near oncoming traffic gate may then be raised by depressing the NEAR ONCOMING TRAFFIC GATE RAISE push-button. As the near oncoming traffic gate is being raised, the NEAR ONCOMING TRAFFIC GATE LOWERED indicator light will go out. Once the near oncoming traffic gate if fully raised, the NEAR ONCOMING TRAFFIC GATE RAISED indicator light will illuminate.

14) The near off going traffic gates may then be raised by depressing the NEAR OFF GOING TRAFFIC GATE RAISE push-button. As the near off going traffic gate is being raised, the NEAR OFF GOING TRAFFIC GATE LOWERED indicator light will go out. Once the near off going traffic gate is fully raised, the NEAR OFF GOING TRAFFIC GATE RAISED indicator light will illuminate, and the far oncoming traffic gates will be enabled.

15) The far oncoming traffic gates may then be raised by depressing the FAR ONCOMING TRAFFIC GATE RAISE push-button. As the far oncoming traffic gate is being raised, the FAR ONCOMING TRAFFIC GATE LOWERED indicator light will go out. Once the far oncoming traffic gate if fully raised, the FAR ONCOMING TRAFFIC GATE RAISED indicator light will illuminate.

16) The normal sequence of operation of the traffic gates may be suspended at any time by depressing the CONTROL POWER push-button. The sequence of operation may then be resumed by pulling out the CONTROL POWER ON push-button, and pulling out the appropriate TRAFFIC GATE RAISE push-button or the sequence may be aborted by pulling out the appropriate TRAFFIC GATE LOWER push-button.

17) Once all the traffic gates are fully raised, the traffic signals may be turned green by turning both the TRAFFIC SIGNAL selector switches to the GREEN position.

K. DRAWBRIDGE OPERATION DURING CIVIL DEFENSE EMERGENCIES

1. During Civil Defense emergencies, normal drawbridge openings will continue, except at the following times:

a. When it becomes necessary for the bridge tender, in the interest of his own personal safety, to evacuate the bridge. Before leaving the bridge, the bridge tender will make sure that the main power switch is turned off and that all doors are closed and locked.

b. When the bridge tender receives instructions from a Pinellas County official not to open…
