TABLE 3.3 ( Continued )
Department of the Navy's List of Categorical Exclusions
17 New activities conducted at established laboratories and plants
(including contractor-operated laboratories and plants) where all
airborne emissions, waterborne efluent, external ionizing and
non-ionizing radiation levels, outdoor noise, and solid and bulk waste
disposal practices are in compliance with existing applicable federal,
state, and local laws and regulations

22 Decommissioning, disposal, or transfer of navy vessels, aircraft,
vehicles, and equipment when conducted in accordance with applicable
regulations, including those regulations applying to removal of
hazardous materials

23 Nonroutine repair and renovation, and donation or other transfer
of structures, vessels, aircraft, vehicles, landscapes, or other
contributing elements of facilities listed or eligible for listing in
the National Register of Historic Places which will result in no
adverse effect

18 Studies, data, and information gathering that involve no permanent
physical change to the environment (e.g., topographic surveys,
wetlands mapping, surveys for evaluating environmental damage

19 Temporary placement and use of simulated target ields (e.g., inert
mines, simulated mines, or passive hydrophones) in fresh, estuarine,
and marine waters for the purpose of non-explosive military training
exercises or research, development, test and evaluation

24 Hosting or participating in public events (e.g., air shows, open
houses, Earth Day events, and athletic events) where no permanent
changes to existing infrastructure (e.g., road systems, parking
and sanitation systems) are required to accommodate all aspects
of the event

20 Installation and operation of passive scientiic measurement
devices (e.g., antennae, tide gauges, weighted hydrophones,
salinity measurement devices, and water quality measurement
devices) where use will not result in changes in operations tempo and
is consistent with applicable regulations

25 Military training conducted on or over nonmilitary land or water
areas, where such training is consistent with the type and tempo of
existing nonmilitary airspace, land, and water use (e.g., night compass
training, forced marches along trails, roads and highways, use of
permanently established ranges, use of public waterways, or use of
civilian airields)

21 Short-term increases in air operations up to 50% of the typical
operation rate, or increases of 50% operations per day, whichever
is greater. Frequent use of this CATEX at an installation requires
further analysis to determine there are no cumulative impacts

26 Transfer of real property from the Department of the Navy to another
military department or to another federal agency
