§323.4. Discharges not requiring permits. — Inbound Citations

(iii) Certain discharges, such as those associated with normal farming, silviculture, and ranching activities, are not prohibited by or otherwise subject to regulation under section 404. See 33 CFR 323.4 for discharges that do not required permits.

(a) Except as provided in § 323.4 of this part, DA permits will be required for the discharge of dredged or fill material into waters of the United States. Certain discharges specified in 33 CFR part 330 are permitted by that regulation (“nationwide permits”). Other discharges may be authorized by district or division engineers on a regional basis (“regional permits”). If a discharge of dredged or fill material is not exempted by § 323.4 of this part or permitted by 33 CFR part 330, an individual or regional section 404 permit will be required for the discharge of dredged or fill material into waters of the United States.

(ii) To fall under this exemption, the activities specified in paragraph (a)(1)(i) of this section must be part of an established (i.e., on-going) farming, silviculture, or ranching operation and must be in accordance with definitions in § 323.4(a)(1)(iii). Activities on areas lying fallow as part of a conventional rotational cycle are part of an established operation. Activities which bring an area into farming, silviculture, or ranching use are not part of an established operation. An operation ceases to be established when the area on which it was conducted has been converted to another use or has lain idle so long that modifications to the hydrological regime are necessary to resume operations. If an activity takes place outside the waters of the United States, or if it does not involve a discharge, it does not need a section 404 permit, whether or not it is part of an established farming, silviculture, or ranching operation.
