PSC 114.234(5) (5) Clearance of supply lines near fuel storage tanks. [Follows NESC 234C5, p. 129] (Addition) Following NESC 234C5 and the PSC 114 addition of paragraph 6, add the following paragraph 7 and exceptions 1 and 2 to read:

7. Clearance of Supply Lines Near Fuel Storage Tanks

Supply lines shall not be run over above-ground flammable liquids and liquefied petroleum gas (LPG) storage tanks. A horizontal clearance of not less than 2.45 m (8 ft) with cables at rest, and not less than 1.80 m (6 ft) with cables displaced by wind according to Rule 234A2, shall be maintained between above-ground flammable liquids and liquefied petroleum gas storage tanks and supply cables of all voltages meeting Rule 230C. A horizontal clearance of not less than 4.6 m (15 ft) with conductors at rest, and not less than 3.0 m (10 ft) with conductors displaced by wind according to Rule 234A2, shall be maintained between such fuel storage tanks and all other supply conductors.

PSC 114.234 Note Exception 1: These requirements do not apply to liquefied petroleum gas tanks with a capacity of 1,000 gallons or less.

PSC 114.234 Note Exception 2: These requirements do not apply to tanks enclosed in a building or fully covered by a roof or canopy capable of preventing falling overhead supply conductors from directly contacting the tank. In this case, the vertical and horizontal clearance requirements of conductors from buildings apply. See Rule 234C.

PSC 114.234(6) (6) Clearance of open supply lines near wells. [Follows NESC 234C5, p. 129] (Addition) Following NESC 234C5 and PSC 114 additions of paragraph 6 and 7, add the following paragraph 8 and exception:

8. Clearance of Open Supply Lines Near Wells

Open supply lines shall not be run over wells. A horizontal clearance with conductors at rest of no less than 3/4 of the vertical clearance of the conductors to ground required by Rule 232, and a horizontal clearance of not less than 3.0 m (10 ft) with conductors displaced by wind according to Rule 234A2, shall be maintained between open supply conductors and wells. Persons installing such wells shall also comply with this requirement.

PSC 114.234 Note Exception: This rule does not apply to Groundwater Monitoring Wells defined in Wis. Admin. Code ch. NR 141 provided such wells are installed using hydraulic push methods, such as a Geoprobe type rig (The vertical clearance required for a Geoprobe is typically less than 10 feet.) and where sampling is accomplished using a bailer or a submersible pump attached to flexible tubing. This exception is not intended to apply to monitoring wells installed with drilling rigs that are taller than 14 feet or sampling methods that require sections of piping (steel or plastic pipe).

PSC 114.234(8) (8) Swimming pools. [NESC 234E1, p. 130] (Addition) Add the following sentence to the beginning of paragraph E1:

1. Swimming Pools

Pools and appurtenances shall not be placed under or near existing service-drop conductors or any other overhead wiring; nor shall such wiring be installed over a swimming pool or the surrounding area unless such installation complies with the clearances or the exceptions specified in NESC Rule 234E1.

PSC 114.234(9) (9) Grain bins loaded by permanently installed augers, conveyers, or elevator systems. [Follows NESC 234F1, p. 131] (Addition) Following 234F1, add exception and note to read:

PSC 114.234 Note Exception: Farm silos that are loaded by a blower through a vertical metal tube permanently attached to the side of the structure are not considered grain bins.

PSC 114.234 Note Note 2: Typical cylindrical farm silos are considered buildings for the purposes of this code and the clearance requirements of NESC Rule 234C, as amended herein, would apply.
