Preparations for any weather event will begin prior to the particular weather season. For hurricane season, non-perishable storm supplies such as batteries, portable generators, flashlights, and radios will be back-stocked and inventoried by the AM Firm monthly to ensure quantity and condition.

Additionally, common spare parts used for the moveable bridges including limit switches, fuses, breakers, relays, and traffic gate hardware will be stocked and supplied to the bridge mechanic’s work trucks to ensure access to the necessary parts in the storm aftermath. Similarly, as the winter season approaches, de-icing agents and winter storm supplies will be stocked and inventoried.

SCDOT TS/Hurricane Terminology for Movable Bridges All parties should have a clear understanding of SCDOT terminology regarding TS/ Hurricane procedures for movable bridges. The following are the only official terms used by SCDOT and its contractors:

Cease Operation: SCDOT and/or the Asset Management Firm will use this terminology to communicate to the USCG, SCDNR, and the traveling public that a movable bridge will no longer open to marine traffic. This will be dictated by sustained wind speeds in excess of 25 mph (or anticipated wind speeds), as well as any other severe weather factors that cause SCDOT to feel it is unsafe to operate a bridge for marine traffic. This term does not necessarily involve any additional measures for the bridge, however, as conditions may worsen, further action may be required.

Tie down: SCDOT will use this terminology to communicate internally and to its contractors that the bridges will have their traffic gates removed, and hurricane tie down measures will be taken for appropriate structures. The AM firm will put hurricane ties in place on swing span structures and ensure that the lock bars are fully engaged for bascule bridges. This process is estimated at 45 minutes (+/-) for swing span structures and 15 minutes (+/-) for bascule bridges.

Abandon Structure: SCDOT will use this terminology to communicate internally and to its contractors that the bridge tender will be removed from the tender house due to impending safety concerns. If this plan of action is put into place, the bridge tender will remain on site for the duration of the tie down procedure and abandon the bridge at the same time as the tie down work crew. At this point, all electrical power to the structure will be disconnected. SCDOT and/or its contractors will also alert the USCG and SCDNR that the structures are no longer staffed, so radio calls from vessels to the bridge tender house will not be answered.

Reopening: SCDOT will use this terminology to communicate internally, as well as to contractors, the USCG, and SCDNR that a movable bridge is being put back into normal operation. This may be as simple as the sustained wind speed reaching a low enough level to resume normal operations, or it may be a longer process that involves installing traffic gates and untying swing span structures.

Approaching Tropical System Procedures The following process will be initiated when the National Weather Service identifies the potential for Tropical Cyclone impacts in the coastal regions of South Carolina:

1. Coordination between SCDOT and the Asset Management Contractor will be initiated 4- 5 days prior to projected severe weather impacts. This coordination will be managed out of the BMO with a designated point of contact in Districts 5 and 6. The decisions for when to cease operation of movable bridges will ultimately be made out of the BMO office, with close discussion and communication with D5 and D6. The Asset Management (AM) firm will be in close communication with the BMO and will be prepared to perform operations, as directed by the BMO.

2. Coordination between SCDOT, the AM firm, and the USCG will occur on the Heavy Weather Advisory Group (HWAG) calls. Any information communicated to the USCG outside of the HWAG calls will be done with the approval of SCDOT.

3. SCDOT and the AM firm will evaluate when to cease operation of movable bridges based on NHC projected onset of tropical storm force or hurricane force winds.

Currently, SC movable bridges are to cease operation at a sustained wind speed of 25 mph. In the event of an expected storm impact during night fall or other storm specific factors (such as lightning and severe rainfall), SCDOT and its contractors will prioritize the safety of the workers performing further storm operations by ceasing movable bridge operation and any further actions before the onset of dangerous conditions.

4. SCDOT and its contractors will try and provide as much time for vessels to seek safe harbor as practical. SCDOT and/or its contractors will announce a “cease operation” time that will encourage prudent planning by marine vessels, but will remain flexible and in close communication with the USCG and SCDNR to make the best decisions possible as weather conditions evolve.

Movable Bridge Cease Operation and Further Action Procedures The following process will be followed in the event that any movable structure ceases operation and/or any further action as a result of a storm event:

1. The AM firm will regularly be in positive communication with the BMO to provide real time updates for the status of the bridges. This communication includes updates on weather conditions at the bridges prior to ceasing operation, when individual bridges cease operation, and continued updates for each structure as any further action is deemed necessary. These updates will continue throughout reopening procedures as well. SCDOT will designate a responsible entity in the BMO for coordinating movable bridge timeframes. This person at the BMO will be kept up to date with real time notifications of weather at each structure, as well as, the status of any ongoing storm preparations at each structure.

2. If a plan has been activated to cease operation and/or any actions taken further than this for a movable bridge, tenders will communicate this cease operation to any vessel requiring an opening. Additionally, when a structure ceases operation and/or any actions taken further than this, bridge tenders in the same area will communicate these actions with one another. This case is especially important for the two structures in Horry County, as they are only 17.7 miles apart, and the majority of mariners attempting to pass one of the structures are likely intending to pass the other as well. From the time that one of the structures ceases operation, the adjacent structure(s) will be notified. Additionally, it is likely that this cease in operation was anticipated, so any vessels requiring openings in the hour (+/-) prior to the anticipated cease operation of structures in the area will be notified of this and documented by the tender. This vessel information will be relayed to the adjacent structure’s tender so as to not trap vessels in between two structures. Once a structure ceases operation, adjacent structures that may still be operating will be required to notify any vessels requesting an opening that the other structure(s) have ceased operation and will not be able to open. The tender will also inform the vessel that this current structure is likely to cease operation as well before they are allowed to open the bridge. If the vessel still wishes to proceed through the bridge, and the bridge is still able to open, the tender will be required to get the vessel information, as well as, a form of contact for the vessel in the event the vessel becomes stranded. This will allow SCDOT and/or other entities to reach out to potential vessels in the event that any planned and announced timeframes need to be accelerated due to changing weather conditions.

3. SCDOT and its contractors will not attempt to publish expected timeframes for tying down and abandoning structures. Published information will be limited to the planned cease of operations and the reopening of structures. The responsible party in the BMO will decide if and when to tie down and/or abandon structures. If a tie down plan is initiated, the structures are to remain fully operational until the SCDOT directed tie down time, unless sustained wind speeds or other storm factors cause the structures to cease operation prior to a tie down order. A tie down order does not include removing tenders from structures. Tenders will not abandon their structures until the “Abandon Structure” order has been given by SCDOT to the AM firm.

4. SCDOT and its contractors will attempt to reopen structures as quickly and safely as possible after the dissipation of tropical storm force winds. Suspension of normal vehicular traffic restrictions will be considered when reopening procedures are to occur during a traffic restricted time. The BMO will communicate with the DEAs (D5 and D6) to determine if an exemption can be made for this restriction. Specifically, this exemption will be pursued to get structures back to normal operations so that the USCG can conduct post-storm event operations on the Intracoastal Waterway.

During the reopen phase, the AM will have the assigned teams stationed within the appropriate regions and able to mobilize quickly to their assigned structures to begin the condition assessment of the structure. If requested, AM will activate on-call engineering support to provide emergency bridge inspection services. Once the safety of the structure has been confirmed, and the BMO has provided notification, AM teams will immediately begin to reinstall gates and reopen the bridges.

Current Asset Manager Tropical System Internal Operations Plan Moveable Bridge Response

The moveable bridges on this contract are the most susceptible to the damaging effects of wind and high volumes of water produced by a severe coastal storm. The AM firm’s storm preparations and level of readiness (LOR) start at five days or 120 hours from a potential storm impact, including severe wind and flooding. At this time, the Project Manager will meet with the management team to ascertain the inventory of storm supplies and acquire any necessary items to perform all storm related activities. The upcoming maintenance schedule and resource allocations will be reviewed and adjusted to allow for staff to prepare and complete storm related preparations and tasks in the coming days. Any maintenance activities that are necessary for continued operation of the movable bridges will be brought forward if possible, with the intention that these activities will be completed prior to a storm event. The AM team will be on stand-by to provide emergency bridge inspection services and traffic control assistance related to storm response if called upon by SCDOT.

At 96 hours from a projected impact of bridge operations, the AM team will enter a LOR of 5:

• All employee contacts and emergency contacts will be reviewed for accuracy and updated as necessary.

• Emergency equipment and supplies will be replenished as needed.

• Truck fuel levels will be topped off and plans for moving the fleet in-land will be developed/reviewed.

• Functionality and fuel levels for all emergency generators will be verified and addressed as necessary.

At 72 hours from a projected impact of bridge operations, the AM team will enter a LOR of 4:

• The PM, DPM, APM and/or OM will begin participating in the USCG Heavy Weather Advisory Call for the Port of Charleston and any SCDOT conference calls as necessary.

• AM team will ensure all SCDOT contacts and emergency phone numbers are current and up-to-date.

• Staff and equipment will be assigned and put on alert to respond to each geographic region of the project, and mechanics will be assigned to specific moveable bridges for tie-down procedures (assignments will be continually adjusted and refined as storm forecast data changes).

• Specific teams will be developed for the specific bridges impacted to assign resources where needed.

• Plans will be implemented to stage personnel and equipment for post-storm response.

Teams will be remain in the region to return to the bridges assigned. Each team will have an electrician available to ensure the power can be safely removed and restored to the assigned bridges.

• All bridge mechanic’s vehicles will be stocked or re-stocked as needed with storm supplies including portable generators, flashlights, batteries, and radios.

• Employees will be allowed to secure personal property and begin to implement personal emergency action plans.

• AM will ensure all swing bridge tie-downs are properly lubricated and fully functional.

At 48 hours from a projected impact of bridge operations, the AM team will enter a LOR of 3:

• Vehicles and equipment will be topped off with fuel.

• Unnecessary equipment and vehicles will be moved to a secure location in-land.

• Emergency generators will be topped off with fuel to at or above 90% full.

• Hotel arrangements will be made for response teams near their assigned structures, including bridge captains, to remain within the region and be prepared to respond in the storm aftermath. At least two of the PM, DPM, APM and OM, will remain along with the maintenance technicians and bridge captains as needed. Assignments and specific staff will depend on the projected impacted area and storm intensity as forecast 24 to 48 hours out. Should staff be able to shelter at home safely while meeting the needs of their assigned structures, then no additional accommodations are needed.

At 24 hours from projected impact, the AM team will enter a LOR 2:

• Non-essential employees (Maintenance Staff not assigned to storm preparations, administrative staff and bridge tenders not scheduled for work during the predicted storm impact timeframe) will be released to address personal needs and evacuate if necessary.

• Assigned staff will mobilize to the assigned regions and prepare to implement any necessary tie-down procedures as instructed by SCDOT. At this point assigned staff will remain on-call and available within their assigned region until operations return to normal.

• On-call engineering services will be placed on stand-by and prepare to mobilize to the assigned region to perform post-storm inspections as requested.

• Emergency food/water supplies will be stocked to sustain one individual for up to 3 days.

At 12 hours from predicted project impact, the AM team will enter a LOR 1:

• Assigned staff will be in-place and ready to implement tie-down procedures within an hour of notification from the BMO.

• Storm activity will be monitored closely, so staff can react to sudden changes in storm track and intensity.

• All staff’s personal arrangements will be confirmed and non-essential employee return to work availability and timeframes will be noted.

Evacuation Procedures This section outlines any procedures and protocols that may differ from the standard SCDOT TS/Hurricane policies under an SC Governor Coastal Evacuation Order.

In the event the SC Governor issues a Coastal Evacuation Order for any portions of the SC Low- Country, the BMO may shift pre-storm movable bridge operational procedures to align with the USCG Status of the Port Conditions (appendix B). The BMO will remain in close communication with USCG Sector Charleston as the Port Conditions decline.

Once the USCG Captain of Port establishes the Port of Charleston is Condition Yankee, the BMO may choose to Cease Operation for any or all structures. This will suspend all standard on demand and scheduled vessel openings, and shift operations to opening the bridges only with approval from the BMO (appendix C). During this operational status, the SCDOT movable bridges will remain staffed and fully functional in the event an opening is deemed necessary by the BMO and USCG, but the BMO is not required to approve any or all non-emergency requested openings. Each request will be assessed and handled on a case by case basis.

Once the USCG Captain of Port establishes the Port of Charleston is Condition Zulu, the BMO may choose to suspend all openings for movable bridges until post-storm operations begin. The BMO may initiate Tie-Down and Abandon Structure procedures for any and all movable structures. The USCG will be notified of the decision and informed as each bridge has power shut off and staff removed. The BMO will prioritize the safety of bridge tenders and Tie-Down work crew to prepare the structures for the approaching storm.

Fixed Structure Response The AM team will provide emergency bridge inspection services and traffic control assistance related to incident response if called upon by SCDOT. Additionally, the following tasks will be performed by the AM firm in preparation for severe weather and high wind events (sustained winds > 25 mph) if conditions require:

• The trash cans on the Ravenel Bridge will have the lids secured to the cans. This will be accomplished utilizing two elastic straps per trash can.

• The AM firm will ensure that sidewalk hatches on the Ravenel are secured.

• The AM firm will confirm the traveler on the Ravenel Bridge is docked and chain secured per the plans/manual prior to the onset of severe weather conditions. Currently, the traveler is locked-out and cannot be moved.

• The AM firm will be directed by the BMO to disconnect the electrical service to the JIC and the Ravenel if storm surge is expected to inundate the service points. Time of highest storm surge needs to be monitored in conjunction with high tides and moon phases.

• All tower hatches and doors on the Ravenel Bridge will be secured and locked. This includes the hatches/doors at the top of the towers, the strut level below the roadway and at the tower base.

• The AM firm will be responsible for monitoring, tracking, and reporting the wind speed and tilt monitors on the Ravenel during storm events. The AM firm will verify the systems are functioning and have fully charged batteries at least 24 hours prior to the projected onset of tropical storm force winds. The AM firm will provide periodic wind and tilt reports as requested by SCDOT.

Flooding/High Water Procedures- District 5 The AM firm will monitor water levels and projected high water marks for Socastee and Little River Swing Bridges during any high water event, specifically events that cause large amounts of rainfall in Southeastern North Carolina. The AM firm is responsible for regularly updating the BMO of the water levels, and the BMO may make the decision to have the AM firm remove the electrical motors at Socastee if the anticipated water level is high enough to inundate the bridge components.

Winter Weather Procedures During winter months, ice can form on the stay-cables of the Ravenel Bridge, through-truss members of the Don Holt, and through truss members of the swing bridges. The ice sheets are known to fall into traffic and cause a safety hazard. The AM team will continuously monitor temperature, humidity and wind chill data when temperatures are within 5 degrees of freezing via access to the SCDOT website. Visual inspection of the cables will be done at night and first thing in the morning of days where the conditions are right for ice formation. If the formation of ice sheets has occurred, AM will immediately communicate with SCDOT and potentially local law enforcement to coordinate the proper response action, which may include a full or partial closure of the bridge until the ice has melted.

Appendix C- Approval Process for Evacuation Openings SCDOT Movable Bridge Evacuation Internal Procedures under Condition Yankee.

Procedure for Approval of Movable Bridge Openings in Horry, Charleston, and Beaufort Counties during Cease Operations phase of storm preparation and evacuation:

- Vessel makes a call to the tender on radio or telephone requesting an opening

- Tender fills out the Approval Form obtaining information for BMO to make decision

- Tender calls Primary/Secondary POC and provides the following observations and information:

o traffic observations o current wind conditions o boat type (commercial or personal) o any urgency expressed by boat captain o any intentions the vessel has to return through this bridge or attempt to pass any other SCDOT movable bridges prior to the storm

- Primary/Secondary POC will call SCDOT SBDM or Designee, relay the information from the tender, and either o request permission from the BMO to open the bridge or o recommend against opening the bridge

- SCDOT will make the decision to permit/deny opening and advise the AM POC

- AM POC will call the tender and advise them of the decision and direct the tender to advise the boat captain

- In Horry County, once a boat passes the Socastee, it will be assumed that it needs to pass Little River and vice versa. This will be taken into account when the BMO makes the approval decision, and the adjacent structure will be notified if an opening is approved.

- In Charleston, the same scenario will be taken into consideration for Wappoo and the Ben Sawyer.
