NAC459.9937. Marina storage tanks: Dispensing equipment.

     1. A control must be installed that will permit the fuel delivery pump to operate only when a dispensing nozzle is removed from its bracket or normal position with respect to the dispensing device and only when the switch on the dispensing device is manually actuated. The control must also stop the pump when all nozzles have been returned either to their brackets or to the normal nondispensing position.

     2. Dispensers not integral with the tank must have sumps with operating leak-monitoring sensors that automatically shut off the electricity to the pumping device.

     3. Dispenser hoses must be checked and a record kept on a daily basis for evidence of blistering, carcass saturation or separation, for cuts, nicks or abrasions that expose reinforced material, and for slippage, misalignment or leaks at couplings. Defective hoses must be removed from service within 48 hours after evidence of failure.

     4. At least once each month, each dispenser hose must be completely extended and inspected as follows:

     (a) The hose couplings and the first 12 inches of hose adjacent to the couplings must be examined.

     (b) The dispenser hose must be checked for structural weakness evidenced by soft spots by pressing the hose in the area around its entire circumference. Any hose that shows evidence of soft spots must be removed from service.

     5. Any dispensing nozzle used at a marina service station must be equipped with a nondrip check valve.

     6. Daily and monthly inspections of dispenser hoses are not required when a marina is closed during the off-season.
