Sec. 122.3  Exclusions.

    The following discharges do not require NPDES permits:
    (a) Any discharge of sewage from vessels, effluent from properly 
functioning marine engines, laundry, shower, and galley sink wastes, or 
any other discharge incidental to the normal operation of a vessel. This 
exclusion does not apply to rubbish, trash, garbage, or other such 
materials discharged overboard; nor to other discharges when the vessel 
is operating in a capacity other than as a means of transportation such 
as when used as an energy or mining facility, a storage facility or a 
seafood processing facility, or when secured to a storage facility or a 
seafood processing facility, or when secured to the bed of the ocean, 
contiguous zone or waters of the United States for the purpose of 
mineral or oil exploration or development.
    (b) Discharges of dredged or fill material into waters of the United 
States which are regulated under section 404 of CWA.
    (c) The introduction of sewage, industrial wastes or other 
pollutants into publicly owned treatment works by indirect dischargers. 
Plans or agreements to switch to this method of disposal in the future 
do not relieve dischargers of the obligation to have and comply with 
permits until all discharges of pollutants to waters of the United 
States are eliminated. (See also Sec. 122.47(b)). This exclusion does 
not apply to the introduction of pollutants to privately owned treatment 
works or to other discharges through pipes, sewers, or other conveyances 
owned by a State, municipality, or other party not leading to treatment 
works.
    (d) Any discharge in compliance with the instructions of an On-Scene 
Coordinator pursuant to 40 CFR part 300 (The National Oil and Hazardous 
Substances Pollution Contingency Plan) or 33 CFR 153.10(e) (Pollution by 
Oil and Hazardous Substances).
    (e) Any introduction of pollutants from non point-source 
agricultural and silvicultural activities, including storm water runoff 
from orchards, cultivated crops, pastures, range lands, and forest 
lands, but not discharges from concentrated animal feeding operations as 
defined in Sec. 122.23, discharges from concentrated aquatic animal 
production facilities as defined in Sec. 122.24, discharges to 
aquaculture projects as defined in Sec. 122.25, and discharges from 
silvicultural point sources as defined in Sec. 122.27.
    (f) Return flows from irrigated agriculture.
    (g) Discharges into a privately owned treatment works, except as the 
Director may otherwise require under Sec. 122.44(m).
    (h) The application of pesticides consistent with all relevant 
requirements under FIFRA (i.e., those relevant to protecting water 
quality), in the following two circumstances:
    (1) The application of pesticides directly to waters of the United 
States in order to control pests. Examples of such applications include 
applications to control mosquito larvae, aquatic weeds, or other pests 
that are present in waters of the United States.
    (2) The application of pesticides to control pests that are present 
over waters of the United States, including near such waters, where a 
portion of the pesticides will unavoidably be deposited to waters of the 
United States in order to target the pests effectively; for example, 
when insecticides are aerially applied to a forest canopy where waters 
of the United States may be present below the canopy or when pesticides 
are applied over or near water for control of adult mosquitoes or other 
pests.

    (i) Discharges from a water transfer. Water transfer means an 
activity that conveys or connects waters of the United States without 
subjecting the transferred water to intervening industrial, municipal, 
or commercial use. This exclusion does not apply to pollutants 
introduced by the water transfer activity itself to the water being 
transferred.
