c. Pumps. <br /> (1 ) Remote pumping system utilizing submerged transfer pumps (STP°s) <br /> to transport product must be equipped with pipeline leak detector on <br /> discharge side of pump capable of interrupting product flow if there is a <br /> drop in pressure`in the delivery line. <br /> (2) Section pumping systems have built-in leak detection <br /> capabilities but, for effective leak detection, the only check valve in the <br /> line must be at the tank. <br /> 3. TEMPORARY OR PERMANENT FACILITY CLOSURE/ABANDONMENT. <br /> a.
