PCB Regulations — 25
Storage requirements 25 The owner or operator of a PCB storage site shall (a) store all PCBs or products containing PCBs that are in liquid form in (i) sealed containers, other than drums, that are made of steel or other metals that provide sufficient durability and strength to prevent those PCBs or products from being affected by the weather or released, or (ii) drums that are (A) of a capacity not greater than 205 L, (B) a closed-head double-bung drum made of steel having a gauge of 16 or heavier, and (C) painted or treated to prevent rusting; (b) store all PCBs or products containing PCBs that are in solid form in (i) containers, other than drums, that are made of steel or other materials that provide sufficient durability and strength to prevent those PCBs or products from being affected by the weather or released, or (ii) drums that are (A) of a capacity not greater than 205 L, (B) made of steel having a gauge of 18 or heavier, (C) equipped with a securely attached, removable steel lid and a gasket made of material that is resistant to the PCBs or the products containing PCBs that are stored in the drums, and (D) painted or treated to prevent rusting; (c) store equipment containing PCB liquids in (i) containers, other than drums, that are made of steel or other materials that provide sufficient durability and strength to prevent the equipment from being affected by the weather and to prevent any PCB liquid that leaks from the equipment from being released, or (ii) drums described in subparagraph (b)(ii); (d) store all equipment that is not in a container, other than drained equipment, if that equipment contains PCB liquid, and all containers of PCB liquid, on a floor or surface that is made of steel, concrete or any other similar durable material and that is constructed with curbing or sides that are capable of containing (i) if one piece of equipment or one container is being stored, 125% of the volume of the PCB liquid in the equipment or container, and (ii) if more than one piece of equipment or more than one container is being stored, the greater of twice the volume of the PCB liquid in the largest piece of equipment or the largest container and 25% of the volume of all the PCB liquid stored on the floor or surface; (e) if the material of the floor or surface or the curbing or sides referred to in paragraph (d) are capable of absorbing any PCB liquid or other product containing PCBs, seal the floor, surface, curbing or sides with an impervious, durable, PCB-resistant coating; (f) ensure that all floor drains, sumps or other openings in the floor or surface referred to in paragraph (d) are (i) closed and sealed to prevent the release of liquids, or (ii) connected to a drainage system suitable for liquid dangerous goods that terminates at a location where any spilled liquids will be contained and recovered and where the spilled liquids will not create a fire hazard or a risk to public health or safety; (g) place on skids or pallets all equipment containing PCBs and containers of PCBs or products containing PCBs that are not permanently secured to the floor or a surface; (h) stack containers of PCBs and products containing PCBs, other than drums, only if the containers are designed for stacking, and stack containers of PCB liquid not more than two containers high; (i) if drums containing PCBs or products containing PCBs are stacked, separate the drums from each other with pallets and, in the case of drums of PCB liquid, stack the drums not more than two drums high; (j) store equipment containing PCBs, and containers of PCBs or products containing PCBs, in a manner that makes them accessible for inspection; (k) store PCBs or products containing PCBs in a manner that prevents them from catching fire or being released; (l) store PCBs or products containing PCBs together, and separate them from other stored materials; (m) if reasonably practicable, equip any indoor PCB storage site having a mechanical exhaust system with hea
