He shall see thatall laws, rules, and regulations forthe use of the lock and lock area areduly complied with, to which end he isauthorized to give all necessary ordersand directions in accordance therewith,both to employees of the Government andto any and every person within thelimits of the lock or lock area,whether navigating the lock or not. Noone shall cause any movement of anyvessel, boat, or other floating thingin the lock or approaches except by orunder the direction of the lockmasteror his assistants. In the event of anemergency, the lockmaster may departfrom these regulations as he deemsnecessary. The lockmasters shall alsobe charged with the control andmanagement of federally constructedmooring facilities.The following safety rules are herebyprescribed for vessels in the lockingprocess, including the act ofapproaching or departing a lock:I) Tows with flammable or hazardouscargo barges, loaded or empty(i) Stripping barges or transferringcargo is prohibited.(ii) All hatches on barges used totransport flammable or hazardousmaterials shall be closed and latched,except those barges carrying a gas-freecertificate.(iii) Spark-proof protective rubbingfenders ("possums") shall be used.II) All Vessels(i) Leaking vessels may be excludedfrom locks until they have beenrepaired to the satisfaction of theLockmaster.(ii) Smoking, open flames, and chippingor other spark producing activities areprohibited on deck during the lockingcycle.b) Safety Rules for Vessels UsingNavigation LocksUNITED STATES ARMY CORPS OF ENGINEERS – LOUISVILLE DISTRICTREGULATIONS - SHEET C

REGULATIONS PRESCRIBED BY THE SECRETARY OF THE ARMYFOR THE OHIO RIVER ABOVE CAIRO, IL AND ITS TRIBUTARIES;USE, ADMINISTRATION, AND NAVIGATION(iii) Painting will not be permitted inthe lock chamber during the lockingcycle.(iv) Tow speeds shall be reduced to arate of travel such that the tow can bestopped by checking should mechanicaldifficulties develop. Pilots shouldcheck with the individual lockmastersconcerning prevailing conditions. Itis also recommended that pilots checktheir ability to reverse their energiesprior to beginning an approach.Engines shall not be turned off in thelock until the tow has stopped and beenmade fast.(v) U.S. Coast Guard Regulationsrequire all vessels to have on boardlife saving devices for prevention ofdrowning. All crew members of vesselsrequired to carry work vests (lifejackets) shall wear them during alockage, except those persons in anarea enclosed with a handrail or otherdevice which would reasonably precludethe possibility of falling overboard.All deckhands handling lines duringlocking procedures shall wear a lifejacket. Vessels not required by CoastGuard Regulations to have work vestsaboard shall have at least theprescribed life saving devices, locatedfor ready access and use if needed.The lockmaster may refuse lockage toany vessel which fails to conform tothe above.c) Reporting of Navigation IncidentsIn furtherance of increased safety onwaterways the following safety rulesare hereby prescribed for allnavigation interests:I) Any incident resulting inuncontrolled barges shall immediatelybe reported to the nearest lock. Thereport shall include information as tothe number of loose barges, theircargo, and the time and location wherethey broke loose. The lockmaster orlocks shall be kept informed of theprogress being made in bringing thebarges under control so that he caninitiate whatever actions may bewarranted.II) Whenever barges are temporarilymoored at other than commercialterminals or established fleetingareas, and their breaking away couldendanger a lock, the nearest lock shallbe so notified, preferably thedownstream lock.III) Sunken or sinking barges shall bereported to the nearest lock bothdownstream and upstream of the locationin order that other traffic passingthese points may be advised of thehazards.IV) In the event of an oil spill,notify the nearest lock downstream,specifying the time and location of theincident, type of oil, amount of spill,and what recovery or controllingmeasures are being employed.V) Any other activity on the waterwaysthat could conceivably endangernavigation or a navigation structureshall be reported to the nearest lock.VI) Whenever it is necessary to reportan incident involving uncontrolled,sunken or sinking barges, the cargo inthe barges shall be accuratelyidentified.d) Precedence at LocksI) The vessel arriving first at a lockshall normally be first to lockthrough, but precedence shall be givento vessels belonging to the UnitedStates. Licensed commercial passengervessels operating on a publishedschedule or regularly operating in the"for hire" trade shall have precedenceover cargo tows and like craft.Commercial cargo tows shall haveprecedence over recreational craft,except as described in paragraph (f).UNITED STATES ARMY CORPS OF ENGINEERS – LOUISVILLE DISTRICTREGULATIONS – BACK SHEET C

REGULATIONS PRESCRIBED BY THE SECRETARY OF THE ARMYFOR THE OHIO RIVER ABOVE CAIRO, IL AND ITS TRIBUTARIES;USE, ADMINISTRATION, AND NAVIGATIONII) Arrival posts or markers maybeestablished above and/ or below thelocks. Vessels arriving at or oppositesuch posts or markers will beconsidered as having arrived at thelocks within the meaning of thisparagraph. Precedence may beestablished visually or by radiocommunication. The lockmaster mayprescribe such departure from thenormal order of precedence as in hisjudgment is warranted to achieve bestlock utilization.e) Unnecessary Delay at LocksMasters and pilots must use everyprecaution to prevent unnecessary delayin entering or leaving locks. Vesselsfailing to enter locks with reasonablepromptness when signaled to do so shalllose their turn. Rearranging orswitching of barges in the locks or inapproaches is prohibited unlessapproved or directed by the lockmaster.This is not meant to curtail"jackknifing" or set-overs wherenormally practiced.f) Lockage of Recreation CraftIn order to fully utilize the capacityof the lock, the lockage ofrecreational craft shall be expeditedby locking them through with commercialcraft, provided that both parties agreeto joint use of the chamber. Whenrecreational craft are lockedsimultaneously with commercial tows,the lockmaster will direct, wheneverpracticable, that the recreationalcraft enter the lock and depart whilethe tow is secured in the lock.Recreational craft will not be lockedthrough with vessels carrying volatilecargoes or other substances likely toemit toxic or explosive vapors. If thelockage of recreational craft can notbe accomplished within the timerequired for three other lockage ofrecreational craft shall be made.Recreational craft operators areadvised that many locks have a pullchain located at each end of the lockwhich signals the lockmaster thatlockage is desired.g) Simultaneous Lockage of Tows withDangerous CargoesSimultaneous lockage of other tows withtows carrying dangerous cargoes orcontaining flammable vapors normallywill only be permitted when there isagreement between the lockmaster andboth vessel masters that thesimultaneous lockage can be executedsafely. He shall make a separatedecision each time such action seemssafe and appropriate, provided:I) The first vessel, or tow in, and thelast vessel, or tow out, are securedbefore the other enters or leaves.II) Any vessel or tow carryingdangerous cargoes is not leaking.III) All masters involved have agreedto the joint use of the lock chamber.h) Stations While Awaiting LockageVessels awaiting their turn to lockshall remain sufficiently clear of thestructure to allow unobstructeddeparture for the vessel leaving thelock. However, to the extentpracticable under the prevailingconditions, vessels and tows shallposition themselves so as to minimizeapproach time when signaled to do so.i) Stations While Awaiting AccessThrough Navigable PassWhen navigable dams are up or are inthe process of being raised or lowered,vessels desiring to use the pass shallwait outside the limits of the approachpoints unless authorized otherwise bythe Lockmaster.j) SignalsSignals from vessels shallordinarily be by whistle; signalsfrom locks to vessels shall be bywhistle, another sound device, orvisual means.UNITED STATES ARMY CORPS OF ENGINEERS – LOUISVILLE DISTRICTREGULATIONS - SHEET D

REGULATIONS PRESCRIBED BY THE SECRETARY OF THE ARMYFOR THE OHIO RIVER ABOVE CAIRO, IL AND ITS TRIBUTARIES;USE, ADMINISTRATION, AND NAVIGATIONWhen a whistle is used, long blastsof the whistle shall not exceed 10seconds and short blasts of thewhistle shall not exceed 3 seconds.Where a lock is not provided with asound or visual signal installation,the lockmaster will indicate byvoice or by the wave of a hand whenthe vessels may enter or leave thelock. Vessels must approach thelocks with caution and shall notenter nor leave the lock untilsignaled to do so by the lockmaster.The following lockage signals areprescribed:I) Sound Signals by Means of aWhistleThese signals apply at either asingle lock or twin locks.(i) Vessels desiring lockage shallon approaching a lock give thefollowing signals at a distance ofnot more than one mile from thelock:(a) If a single lockage only isrequired: One long blast of thewhistle followed by one short blast.(b) If a double lockage is required:One long blast of the whistlefollowed by two short blasts.(ii) When the lock is ready forentrance, the lock will give thefollowing signals:(a) One long blast of the whistleindicates permission to enter thelock chamber in the case of a singlelock or to enter the landwardchamber in the case of twin locks.(b) Two long blasts of the whistleindicates permission to enter theriverward chamber in the case oftwin locks.(iii) Permission to leave the lockswill be indicated by the followingsignals given by the lock:(a) One short blast of the whistleindicates permission to leave thelock chamber in the case of a singlelock or to leave the landwardchamber in the case of twin locks.(b) Two short blasts of the whistleindicates permission to leave theriverward chamber in the case oftwin locks.(iv) Four or more short blasts ofthe lock whistle delivered in rapidsuccession will be used as a meansof attracting attention, to indicatecaution, and to signal danger. Thissignal will be used to attract theattention of the captain and crewsof vessels using or approaching thelock or navigating in its vicinityand to indicate that somethingunusual involving danger orrequiring special caution ishappening or is about to take place.When this signal is given by thelock, the captains and crew ofvessels in the vicinity shallimmediately become on the alert todetermine the reason for the signaland shall take the necessary stepsto cope with the situation.II) Lock Signal LightsAt locks where density of traffic orother local conditions make itadvisable, the sound signals fromthe lock will be supplemented bysignal lights. Flashing lights(showing a one-second flash followedby a two-second eclipse) will belocated on or near each end of theland wall to control use of a singlelock or of the landward lock ofdouble locks. In addition, atdouble locks, interrupted flashinglights (showing a one-second flash,a one-second eclipse and a onesecond flash, followed by a threesecond eclipse) will be located onor near each end of the intermediatewall to control use of the riverwardlock. Navigation will be governedas follows:UNITED STATES ARMY CORPS OF ENGINEERS – LOUISVILLE DISTRICTREGULATIONS – BACK SHEET D

REGULATIONS PRESCRIBED BY THE SECRETARY OF THE ARMYFOR THE OHIO RIVER ABOVE CAIRO, IL AND ITS TRIBUTARIES;USE, ADMINISTRATION, AND NAVIGATIONII) Outside of Locks(i) No vessel or other craft shallregularly or permanently moor in anyreach of a navigation channel. Theapproximate centerline of suchchannels is marked as the sailingline on Corps of Engineersnavigation charts. Nor shall anyfloating craft, except in anemergency, moor in any narrow orhazardous section of the waterway.Furthermore, all vessels or othercraft are prohibited from regularlyor permanently mooring in anysection of navigable waterways whichare congested with commercialfacilities or traffic unless it ismoored at facilities approved by theSecretary of the Army or hisauthorized representative. Thelimits of the congested areas shallbe marked on Corps of Engineersnavigation charts. However, theDistrict Engineer may authorize inwriting exceptions to any of theabove if, in his judgment, suchmooring would not adversely affectnavigation and anchorage.(ii) No vessel or other craft shallbe moored to railroad tracks, toriverbanks in the vicinity ofrailroad tracks when such mooringthreatens the safety of equipmentusing tracks, to telephone poles orpower poles, or to bridges orsimilar structures used by thepublic.(iii) Except in case of greatemergency, no vessel or craft shallanchor over revetted banks of theriver, and no floating plant otherthan launches and similar smallcraft shall land against banksprotected by revetment except atregular commercial landings. In allcases, every precaution to avoiddamage to the revetment works shallbe exercised. The construction oflog rafts along mattressed or pavedbanks or the tying up and landing oflog rafts against such banks shallbe performed in such a manner as tocause no damage to the mattress workor bank paving. Generally, mattresswork extends out into the river 600feet from the low water line.(iv) Any vessel utilizing afederally constructed mooringfacility (e.g. cells, buoys, anchorrings) at the points designated onthe current issue of the Corpsnavigation charts shall advise thelockmaster at the nearest lock thatfrom point by the most expeditiousmeans.n) Draft of VesselsNo vessel shall attempt to enter alock unless its draft is at leastthree inches less than the leastdepth of water over the guard sillsor over the gates sills if there beno guard sills. Informationconcerning controlling depth oversills can be obtained from thelockmaster at each lock or byinquiry at the office of thedistrict engineer of the district inwhich the lock is located.o) Handling MachineryNo one but employees of the UnitedStates shall move any lock machineryexcept as directed by thelockmaster.
