The purpose of this Rule is to clarify how the Agency shall manage stream alterations during emergencies and otherwise.
It is the policy of the State to promote and protect the natural maintenance and natural restoration of dynamic equilibrium conditions and to minimize fluvial erosion hazards ( 10 V.S.A. §§ 1021 and 1022 ). The Agency assesses the geomorphic condition and sensitivity of streams and rivers and delineates the corridor necessary to accommodate dynamic equilibrium, naturally stable conditions, and the natural stream processes that would occur in a given location.
Threats to life, public health, and safety or the threat of severe damage to existing improved property are emergencies and may justify stream alterations that may impede the attainment and maintenance of equilibrium conditions and may potentially result in or significantly contribute to damage to fish life, wildlife, or the rights of riparian owners. This Rule acknowledges the tension in some circumstances between threats to life and existing property and the policy of establishing and maintaining stream equilibrium conditions and connectivity to protect fish and aquatic life.
Violations of this Rule are subject to enforcement under applicable Vermont law, including 10 V.S.A. Chapter 41 and 10 V.S.A. Chapters 201 and 211. Failure to comply with the notification requirements of this Rule or to receive authorization for stream alterations and emergency protective measures under a stream alteration general permit ("general permit") or stream alteration individual permit ("individual permit") shall constitute a violation of this Rule.
For the purposes of this Rule, the following terms shall have the specified meaning:

"Stream" does not include ditches or other constructed channels primarily associated with land drainage or water conveyance through or around private or public infrastructure.
A "watercourse" is a perennial stream with surface flows that are not frequently or consistently interrupted during normal seasonal low flow periods. Perennial streams that begin flowing subsurface during low flow periods, due to natural geologic conditions, remain defined as perennial. All other streams, or stream segments of significant length, shall be presumed as intermittent. A watercourse is contained horizontally by its cross-section; including the stream bed and banks. Human caused interruptions of flow (e.g. flow fluctuations associated with hydroelectric facility operations or water withdrawals) shall not influence the Secretary's determination of a perennial stream. A perennial stream shall not include the standing waters in wetlands, lakes, and ponds. For purposes of this Rule, the exclusion of "ditches or other constructed channels primarily associated with land drainage or water conveyance" from the definition of "watercourse" in this Rule shall not be interpreted to include perennial streams that have been excavated and re-formed into a straightened, channelized condition.
A river corridor will be delineated for the purpose of identifying those riparian lands that are required to accommodate the dimensions, slope, planform, and buffer of a naturally stable channel, necessary for the natural maintenance or natural restoration of dynamic equilibrium conditions and for minimization of fluvial erosion hazards. River corridors shall be delineated by the Agency in accordance with river corridor protection procedures ( 10 V.S.A. § 1422(12)) .
Flood hazard areas will be delineated in a manner consistent with the federal definition of an "area of special flood hazard" ( 44 C.F.R § 59.1) , i.e., that land in the floodplain within a community subject to a one percent or greater chance of flooding in any given year ( 10 V.S.A. § 752(3)) .
Pursuant to 10 V.S.A. § 1021, the following activities shall not require a stream alteration permit:
This subpart sets forth a process for the development and issuance of stream alteration general permits.
A general permit issued pursuant to this Rule shall be valid upon signing and shall remain in effect for a period of five years from the date of signing, unless the Secretary specifies a shorter period of time. The process described in subpart 27-503 shall be used when the Secretary reissues a general permit.
The Secretary may modify a general permit after providing an opportunity for public participation in the same manner as described in subpart 27-503 of this Rule. Grounds for modification include:
Emergency protective measures necessary to preserve life or to prevent severe imminent damage to public or private property, or both, shall be limited to the following types of activities:
Appeals from any act or decision of the Secretary under this Rule are governed by 10 V.S.A. § 8504.
