(q) The communications required by §§ 154.560 and 155.785 of this chapter are operable for the transfer operation;
(r) The emergency means of shutdown required by §§ 154.550 and 155.780 of this chapter, as applicable, is in position and operable;
(s) There is a person in charge on the transferring vessel or facility and the receiving vessel or facility except as otherwise authorized under § 156.115;
(t) Each person in charge required by paragraph (s) of this section:
(1) Is at the site of the transfer operation and immediately available to the transfer personnel;
(2) Has readily available in the marine transfer area a copy of the most recently examined facility operations manual or vessel transfer procedures, as appropriate; and
(3) Conducts the transfer operation in accordance with the facility operations manual or vessel transfer procedures, as appropriate;
(u) The personnel required, under the facility operations manual and the vessel transfer procedures, to conduct the transfer operation:
(1) Are on duty; and
(2) Conduct the transfer operation in accordance with the facility operations manual or vessel transfer procedures, as appropriate;
(v) At least one person is at the site of the transfer operation who fluently speaks the language or languages spoken by both persons in charge;
(w) The person in charge of the transfer on the transferring vessel or facility and the person in charge of it on the receiving vessel or facility have held a conference, to ensure that each person in charge understands—
(1) The identity of the product to be transferred;
(2) The sequence of transfer operations;
(3) The transfer rate;
(4) The name or title and location of each person participating in the transfer operation;
(5) Details of the transferring and receiving systems including procedures to ensure that the transfer pressure does not exceed the maximum allowable working pressure (MAWP) for each hose assembly, loading arm and/or transfer pipe system;
(6) Critical stages of the transfer operation;
(7) Federal, state, and local rules that apply to the transfer of oil or hazardous material;
(8) Emergency procedures;
(9) Discharge containment procedures;
(10) Discharge reporting procedures;
(11) Watch or shift arrangement;
(12) Transfer shutdown procedures; and,
(13) If the persons use radios, a predetermined frequency for communications during the transfer, agreed upon by both.
(x) The person in charge of transfer operations on the transferring vessel or facility and the person in charge of transfer operations on the receiving vessel or facility agree to begin the transfer operation;
(y) Between sunset and sunrise the lighting required by §§ 154.570 and 155.790 of this chapter is provided; and
(z) For transfer operations between tank barges from sunset to sunrise, lighting is provided as described in § 155.790 of this chapter.
(aa) A transfer operation which includes collection of vapor emitted to or from a vessel’s cargo tanks through a vapor control system (VCS) not located on the vessel must have the following verified by the person in charge:
(1) Each manual valve in the vapor collection system is correctly positioned to allow the collection of cargo vapor;
(2) A vapor collection hose or arm is connected to the vessel’s vapor connection;
(3) The electrical insulating device required by § 154.810(g) of this chapter or 46 CFR 39.40-3(c) is fitted between the facility vapor connection and the vessel vapor connection;
(4) The initial transfer rate and the maximum transfer rate are determined;
(5) The maximum and minimum operating pressures at the facility vapor connection are determined;
(6) The tank barge overfill control system, if installed, is connected to the facility, tested, and operating properly;
(7) The following have been performed not more than 24 hours prior to the start of the transfer operation or in accordance with 33 CFR 154.2150(b):
(i) Each alarm and automatic shutdown system required by subpart E of part 154 of this chapter and 46 CFR part 39 has been tested and found to be operating properly, and
(ii) Analyzers required by 33 CFR 154.2105(a) and (j) and 154.2107(d) and (e) or 46 CFR 39.40-3(a) have been checked for calibration by use of a span gas;
(8) Each vapor recovery hose has no unrepaired loose covers, kinks, bulges, soft spots, or any other defect which would permit the discharge of vapor through the hose material, and no external gouges, cuts, or slashes that penetrate the first layer of hose reinforcement; and
(9) The oxygen content in the vapor space of each of the vessel’s cargo tanks connected to the vapor collection system, if inerted, is—
(i) At or below 60 percent by volume of the cargo’s minimum oxygen concentration for combustion; or
(ii) At or below 8 percent by volume, at the start of cargo transfer, for vapor of crude oil, gasoline blends, or benzene;
(10) The freezing point of each cargo has been determined. If there is a possibility that the ambient air temperature during transfer operations will be at or below the freezing point of the cargo, adequate precautions have been taken to prevent freezing of vapor or condensate, or to detect and remove the liquid condensate and solids to prevent accumulation;
(11) If the cargo has the potential to polymerize, adequate precautions have been taken to prevent and detect polymerization of the cargo vapors; and
(12) The VCS has been cleaned, in accordance with 33 CFR 154.2150(p), between transfers of incompatible cargoes.
