Sec. 10. (a) Subject to subsection (h), and except as otherwise allowed by IC 36-7-4-1109, a project owner may not install or locate a wind power device on property in a unit unless the distance, measured as a straight line, from the vertical centerline of the base of the wind power device to:
(1) the centerline of any:
(A) runway located on a public use airport, private use airport, or municipal airport;
(B) public use highway, street, or road; or
(C) railroad easement or right-of-way; or
(2) the property line of any nonparticipating property;
is equal to a distance that is at least one and one-tenth (1.1) times the wind power device's blade tip height, as measured from the ground to the tip of the blade.
(b) Subject to subsection (h), and except as otherwise allowed by IC 36-7-4-1109, a project owner may not install or locate a wind power device on property in a unit unless the distance, measured as a straight line, from the vertical centerline of the base of the wind power device to the nearest point on the outer wall of a dwelling located on a nonparticipating property is equal to a distance that is at least three (3) times the wind power device's blade tip height, as measured from the ground to the tip of the blade.
(c) Except as otherwise allowed by IC 36-7-4-1109, a project owner may not install or locate a wind power device on property in a unit unless the distance, measured as a straight line, from the vertical centerline of the base of the wind power device to the nearest edge of the right-of-way for any utility transmission or distribution line is equal to a distance that is at least one and two-tenths (1.2) times the wind power device's blade tip height, as measured from the ground to the tip of the blade.
(d) Except as otherwise allowed by IC 36-7-4-1109, a project owner may not install or locate a wind power device on property in a unit unless the distance, measured as a straight line, from the vertical centerline of the base of the wind power device to the property line of any undeveloped land within the unit that is zoned or platted for residential use is equal to a distance that is at least two (2) times the wind power device's blade tip height, as measured from the ground to the tip of the blade.
(e) Except as otherwise allowed by IC 36-7-4-1109, a project owner may not install or locate a wind power device on property in a unit unless the distance, measured as a straight line, from the vertical centerline of the base of the wind power device to the property line of a state park is equal to a distance of at least one (1) mile.
(f) A project owner may not install or locate a wind power device within a county unless the distance, measured as a straight line, from the vertical centerline of the base of the wind power device to the corporate boundaries of any municipality within the county is equal to a distance of at least one (1) mile. However, a municipality may waive or reduce the minimum distance prescribed by this subsection with respect to the installation of one (1) or more wind power devices.
(g) Except as otherwise allowed by IC 36-7-4-1109, a permit authority, with respect to the permitting, construction, installation, or siting of any wind power device within the unit, may not set a blade tip height limitation, through a wind power regulation or otherwise, that is more restrictive than the standards of the Federal Aviation Administration under 14 CFR Part 77 concerning the safe, efficient use and preservation of the navigable airspace.
(h) The distance requirements set forth in subsections (a)(2) and (b) may be waived with respect to the siting of any one (1) wind power device, subject to the written consent of the owner of each affected nonparticipating property.
