“(C)Agricultural purposes.—The term ‘agricultural purposes’ means farming in all its branches and the cultivation and tillage of the soil, the production, cultivation, growing, and harvesting of any agricultural or horticultural commodities performed by a farmer or on a farm, or on pasture land or rangeland.
“(2)Other definitions.—The Administrator shall define such other terms as may be necessary to carry out this section.
“(c)Database.—The Administrator shall—
“(1) develop a new database, or if appropriate use an existing database that meets the requirements under this section, that contains the location and height of each covered tower that, pursuant to subsection (a), the owner or operator of such tower elects not to mark (unless the Administrator has determined that there is a significant safety risk requiring that the tower be marked), except that meteorological evaluation towers shall be marked and contained in the database;
“(2) keep the database current to the extent practicable;
“(3) ensure that any proprietary information in the database is protected from disclosure in accordance with law;
“(4) ensure that, by virtue of accessing the database, users agree and acknowledge that information in the database—

“(3) shall consider, in establishing exclusions and granting waivers under this subsection, factors that may sufficiently mitigate risks to aviation safety, such as the length of time the tower has been in existence or alternative marking methods or technologies that maintains a tower’s level of conspicuousness to a degree which adequately maintains the safety of the airspace; and
“(4) shall consider excluding towers located in a State that has enacted tower marking requirements according to the Federal Aviation Administration’s recommended guidance for the voluntary marking of meteorological evaluation towers erected in remote and rural areas that are less than 200 feet above ground level to enhance the conspicuity of the towers for low level agricultural operations in the vicinity of those towers.
“(e)Periodic Review.—The Administrator shall, in consultation with the Federal Communications Commission, periodically review any regulations or guidance regarding the marking of covered towers issued pursuant to this section and update them as necessary, consistent with this section, and in the interest of safety of low-altitude aircraft operations.
“(f)FCC Regulations.—The Federal Communications Commission shall amend section 17.7 of title 47, Code of Federal Regulations, to require a notification to the Federal Aviation Administration for any construction or alteration of an antenna structure, as defined in section 17.2(a) of title 47, Code of Federal Regulations, that is a covered tower as defined by this section.”

Landfills Interfering With Air Commerce

Puspan. L. 106–181, title V, § 503(a), Apr. 5, 2000, 114 Stat. 133, provided that: “Congress finds that—

“(1) collisions between aircraft and birds have resulted in fatal accidents;
“(2) bird strikes pose a special danger to smaller aircraft;
“(3) landfills near airports pose a potential hazard to aircraft operating there because they attract birds;
“(4) even if the landfill is not located in the approach path of the airport’s runway, it still poses a hazard because of the birds’ ability to fly away from the landfill and into the path of oncoming planes;
“(5) while certain mileage limits have the potential to be arbitrary, keeping landfills at least 6 miles away from an airport, especially an airport served by small planes, is an appropriate minimum requirement for aviation safety; and
“(6) closure of existing landfills (due to concerns about aviation safety) should be avoided because of the likely disruption to those who use and depend on such landfills.”
