(Persons engaging in some activities which are eligible under this
paragraph and in some which are not, and desiring to use radio in
connections with both types of activities should apply for authorization
in the Business Radio Service.)
(1) The operation of farms, ranches, or similar land areas, for the
quantity production of crops or plants; vines or trees (excluding
forestry operations); or for the keeping, grazing or feeding of

Persons establishing eligibility under this subparagraph may use their
radio facilities in connection with the gathering or processing of
products grown or raised for them by others.
(2) Plowing, soil conditioning, seeding, fertilizing, or harvesting
for agricultural activities.
(3) Spraying or dusting of insecticides, herbicides, or fungicides,
in areas other than enclosed structures.
(4) Livestock breeding service.
(5) The operation of a commercial business regularly engaged in the
construction of roads, bridges, sewer systems, pipelines, airfields, or
water, oil, gas, or power production, collection, or distribution
systems. Other engineering projects, normally classified as heavy
construction activities, will be considered on the merits of the showing
made, however, the construction of buildings is not included in this
category.
(6) The operation of mines for the recovery of solid fuels,
minerals, metal, rock, sand and gravel from the earth or the sea,
including the exploration for and development of mining properties.
(7) Maintaining, patrolling or repairing gas or liquid transmission
pipelines, tank cars, water or waste disposal wells, industrial storage
tanks, or distribution systems of public utilities. Persons establishing
eligibility under this subparagraph may use their radio facilities in
connection with the containment and cleanup of industrial liquid
spillage.
(8) Acidizing, cementing, logging, perforating, or shooting
activities, and services of a similar nature incident to the drilling of
new oil or gas wells, or the maintenance of production from established
wells.
(9) Supplying chemicals, mud, tools, pipe, and other materials or
equipment unique to the petroleum and gas production industry, as the
primary activity of the applicant if delivery, installation or
application of these materials requires the use of specifically fitted
conveyances.
(10) The delivery of ice or fuel to the consumer for heating,
lighting, refrigeration or power generation purposes, by means other

* The frequencies in the band 10.55-10.68 GHz are available for Digital
Termination Systems and for associated internodal links in the Point-
to-Point Microwave Radio Service. No new licenses will be issued under
this subpart but current licenses will be renewed.
(d) Explanation of assignment limitations appearing in the fequency
table of paragraph (c) of this section:
(1) Only entities engaged in exploration, its support services, and
the repair of pipelines are eligible to use this spectrum, and then only
in accordance with Sec. 90.266. Except as provided in this part,
licensees may not use these frequencies in the place of other
operational circuits permitted by the Commission's Rules. The use of
these frequencies is not subject to Sec. 90.73(f). Circuits operating on
these frequencies may be used only for the following purposes:
(i) Exploratory efforts in mining for solid fuels, minerals, and
metals important to the national interest;
(ii) Repair of pipelines used for the transmission of fuel or water;
and,
(iii) Services supporting the exploration for energy or mineral
resources important to the national interest, without which such
exploration cannot be conducted.
(2) This frequency will be assigned only for operation in a
permanent area, normally within 120 km (75 mi.) of a specified reference
point.
(3) Operation on this frequency is limited to a maximum output of 2
watts; and each station authorized will be classified and licensed as a
mobile station. Any units of such a station, however, may provide the
operational functions of a base or fixed station, on a secondary basis
to mobile service operations provided that the separation between the
control point and the center of the radiating portion of the antenna of
any units so used does not exceed 7.6 m (25 ft).
(4) This frequency will be assigned only to stations used in
itinerant operations.
(5) This frequency is shared with the Forest Products Radio Service.
(6) The frequencies available in the band 72-76 MHz are listed in
Sec. 90.257(a)(1). These frequencies are shared with other services and
are available only in accordance with the provisions of Sec. 90.257.
(7) This frequency is available on a shared basis in the
Manufacturers, Forest Products, Special Industrial, Railroad, and Fire
