A. The requirements of this regulation are applicable to oil storage facilities and oil handling facilities with tank car, truck tank, or transport loading/unloading racks or transfer areas.
B. Spill Control.
(1) For a loading/unloading rack or transfer area at an oil storage facility or oil handling facility where a spill, release, or discharge can occur during transfer operations, an owner, an operator, and a person in charge of the facility shall:
(a) Pave the loading/unloading rack or transfer area with a material that has a permeability of 10-7 centimeters/second or less and is resistant to oil;
(b) Maintain the pavement installed in accordance with §B(1)(a) of this regulation to prevent cracking and holes;
(c) Design the loading/unloading rack or transfer area to prevent the entrance of stormwater or wastewater runoff into the loading/unloading rack or transfer area;
(d) Cover the loading/unloading rack or transfer area with a roof;
(e) Include a containment system that prevents oil or stormwater containing oil from discharging to waters of the State by:
(i) Being designed to hold a spill, release, or discharge from the largest single compartment of any tank car, truck tank, or transport loading or unloading oil at the facility; and
(ii) Using permanent curbing, trenching, or other spill control methods approved by the Department; and
(f) Install one or more of the following to prevent a spill, release, or discharge of oil:
(i) An oil/water separator;
(ii) A diked or bermed catchment area that has a permeability of 10-7 centimeters/second or less; or
(iii) An emergency underground holding tank that remains empty unless a spill, release, or discharge occurs.
(2) An owner of an oil storage facility or oil handling facility with a loading/unloading rack or transfer area may be required to obtain a State discharge permit or a National Pollutant Discharge Elimination System permit issued by the Department under Environment Article, §9-323, Annotated Code of Maryland and COMAR 26.08.01—26.08.04 for discharges of stormwater to waters of the State.
(3) If oil is spilled, released, or discharged during an oil transfer, an owner, an operator, and a person in charge of an oil storage facility or oil handling facility shall:
(a) Report the spill, release, or discharge immediately to the Department in accordance with Regulation .05 of this chapter;
(b) Immediately begin the removal of oil; and
(c) Handle the oil and all removal debris in accordance with all State, federal, and local requirements.

(a) That are appropriate for:
(i) The grades of oil being transferred; and
(ii) The most probable size of an anticipated spill, release, or discharge; and
(b) For use in the containment and removal of spilled, released, or discharged oil.
C. Transfer Operations. An owner, an operator, and a person in charge of an oil storage facility or oil handling facility shall:
(1) Install a clearly identifiable switch or shutoff at the loading/unloading rack and at a remote location from the loading/unloading rack area to shut off power to all transfer devices in the event of an emergency;
(2) Provide an interlocking warning light or physical barrier system, warning signs, wheel chocks, or vehicle brake interlock system to prevent a tank car, truck tank, or transport from leaving a loading/unloading area or transfer area before flexible or fixed oil transfer lines are disconnected;
(3) Prior to filling and departure at the oil storage facility or oil handling facility, inspect the lowermost drain and all outlets on the tank car, truck tank, or transport for spills, releases, or discharges; and
(4) If a spill, release, or discharge is found during an inspection, repair or replace the lowermost drain and all outlets on the tank car, truck tank, or transport prior to entering a public transportation system.
