(a) "Fall zone" means the area on the ground within a prescribed radius from the base of a WECS. The fall zone is the area within which there is a potential hazard from falling debris (such as ice) and, in the case of towers, shall not be less than a radius equal in distance to the total height of the WECS.
(b) "Hub height" means the vertical distance from the base of the tower to the center of rotation of the rotor.
(c) "Occupied building" means a residence, school, hospital, church, library, or other building used for public gathering that is occupied or in use when the permit application is submitted.
(d) "Shadow flicker" means the on-and-off flickering effect of a shadow caused when the sun passes behind the rotor of a wind turbine.
(e) "Total height" means the vertical distance from the base of the tower to the tip of a wind generator blade when the tip is at its highest point.
(f) "Tower, monopole" means a wind energy conversion system tower consisting of a single pole, constructed without guyed wires and anchors.
(g) "Wind Energy Conversion System (WECS)" means equipment that converts and then stores or transfers energy from the wind into usable forms of energy and includes any base, blade, foundation, generator, nacelle, rotor, tower, transformer, turbine, vane, wire, or other component used in the system.
(h) "Wind Energy Conversion System, Building Integrated" means a wind energy facility designed to be permanently mounted on an occupied building or accessory structure, designed to be operated in direct contact with a building.
(i) "Wind Energy Conversion System, Medium" means a wind energy system that has a total height of 170 feet or less, and is primarily used to generate energy for use by its owner, reduce the need to purchase utility power from the grid, and has the ability to sell power back to the grid.
(j) "Wind Energy Conversion System, Small" means a wind energy system that has a total height of seventy-five (75) feet or less, and is primarily used to generate energy for use by its owner, reduce the need to purchase utility power from the grid, and has the ability to sell power back to the grid.
