(2) the holder of a permit for construction in a noise sensitive area has filed a copy of the permit for construction in a noise sensitive area with the county recorder of the county in which the structure is located, as provided in subsection (d); and
(3) a certified copy of the recorded permit for construction in a noise sensitive area, with the recording data from the county recorder on the copy of the permit, has been received by the department;
a person may not erect a building used for a noise sensitive purpose within an area lying one thousand five hundred (1,500) feet on either side of the centerline and the extended centerline of a runway for a distance of one (1) nautical mile from the boundaries of any public use airport.
(c) A person applying for a permit under subsection (a) must provide notice, at the time of the filing of the application for a permit, to the owner of a public use airport located within a five (5) nautical mile radius surrounding the structure, regardless of county lines, if the structure that is the subject of the permit is:
(1) a new structure; or
(2) an existing structure to which additional height is added.
(d) A person applying for a permit for construction in a noise sensitive area under subsection (b) must provide notice, at the time of the filing of the application for a permit, to the owner of a public use airport if the public use airport is located within a distance of one (1) nautical mile from the boundary of the property that contains the building used for a noise sensitive purpose.

(f) The applicant for a permit under subsection (b) shall record each permit issued by the department in the office of the county recorder for the county where the structure is located, not later than five (5) business days after the department issues the permit. If a structure is located in more than one (1) county, the county that contains the majority of the structure is the county in which the permit must be filed.

(h) A permit issued under subsection (b) must contain the following statement:
"The permittee acknowledges for itself, its heirs, its successors, and its assigns, that the real estate described in this permit experiences or may experience significant levels of aircraft operations, and that the permittee is erecting a building designed for noise sensitive use upon the real estate, with the full knowledge and acceptance of the aircraft operations as well as any effects resulting from the aircraft operations.".
(i) An applicant for a permit under subsection (a) must provide written evidence to the department that the structure being constructed does not violate section 7 of this chapter with regard to an existing public use airport, if a public use airport is located within a five (5) nautical mile radius surrounding the structure that is the subject of the permit.

(1) the applicant for a permit under subsection (a) submits with the application a Determination of No Hazard to Air Navigation issued by the Federal Aviation Administration to the applicant with regard to the proposed construction or alteration; and

the Determination of No Hazard to Air Navigation is a permit under this section, and a separate permit will not be issued by the department.
(k) The department shall not issue a permit under subsection (a) for construction or alteration of an energy facility that will result in a structure that is more than two hundred (200) feet above ground level at its site unless the applicant for the permit submits to the department documentation from the Military Aviation and Installation Assurance Siting Clearinghouse indicating:
(1) that a formal review of the construction or alteration under 32 CFR 211.6 resulted in a determination that the construction or alteration will not have an adverse impact on military operations and readiness; or
