released
Correct Answer
B) Suction piping is continuously monitored
§ 2636(a)(3). Design, Construction, Installation, Testing, and Monitoring Requirements for Piping
(3) Suction piping if the piping is designed, constructed, and installed as follows:
(A) The below-grade piping operates at less than atmospheric pressure (suction piping);
(B) The below-grade piping is sloped so that the contents of the pipe will drain back into the storage tank if the suction is
released (gravity-flow piping);
(C) No valves or pumps are installed below grade in the suction line. Only one check valve is located directly below and
