Purpose.
It is the intent of the department to provide protection for all fish life through the development of a statewide system of consistent and predictable rules. The department will coordinate with other local, state, and federal regulatory agencies, and tribal governments, to minimize regulatory duplication. Pursuant to chapter 75.20 RCW, this chapter establishes regulations for the construction of hydraulic project(s) or performance of other work that will use, divert, obstruct, or change the natural flow or bed of any of the salt or fresh waters of the state, and sets forth procedures for obtaining a hydraulic project approval (HPA). In addition, this chapter incorporates criteria generally used by the department for project review and conditioning HPAs.

The technical provisions in WAC 220-110-040 through220-110-338 represent common provisions for the protection of fish life for typical projects proposed to the department. Implementation of these provisions is necessary to minimize project specific and cumulative impacts to fish life. These regulations reflect the best available science and practices related to protection of fish life. The department will incorporate new information as it becomes available, and to allow for alternative practices that provide equal or greater protection for fish life.

The technical provisions shall apply to a hydraulic project when included as provisions on the HPA. Each application shall be reviewed on an individual basis. Common technical provisions applicable to a specific project may be modified or deleted by the department pursuant to WAC 220-110-032. HPAs may also be subject to additional special provisions to address project or site-specific considerations not adequately addressed by the common technical provisions.

(a) Work of a seasonal nature that diverts water for irrigation or stock watering purposes.

(b) Streambank stabilization projects if the problem causing the erosion occurs on an annual or more frequent basis as demonstrated by the applicant. Evidence of erosion may include, but is not limited to history of permit application, approval, or photographs. Periodic flood waters by themselves do not constitute the problem that requires a HPA.

(12) A hydraulic project application shall be denied when, in the judgment of the department, the project will result in direct or indirect harm to fish life unless adequate mitigation can be assured by conditioning the HPA or modifying the proposal. If approval is denied, the department shall provide the applicant, in writing, a statement of the specific reason(s) why and how the proposed project would adversely affect fish life.

(13) Protection of fish life shall be the only grounds upon which an HPA may be denied or conditioned.

(14) HPAs may have specific time limitations on project activities to protect fish life.

(15) HPAs do not exempt the applicant from obtaining other appropriate permits and following the rules or regulations of local, federal, and other Washington state agencies.

(16) Administration of this chapter shall be conducted in compliance with SEPA, chapter 43.21C RCW, and chapters197-11, 220-100, and 232-19 WAC.

(17) All HPAs issued pursuant to RCW 75.20.100 and 75.20.160 may be subject to additional restrictions, conditions, or revocation if the department determines that new biological or physical information indicates the need for such action. The permittee has the right to request an informal or formal appeal in accordance with chapter 34.05 RCW. All HPAs issued pursuant to RCW 75.20.103 may be modified by the department due to changed conditions after consultation with the permittee: Provided however, That modifications of HPAs issued pursuant to RCW 75.20.103 and 75.20.160 shall be subject to appeal to the hydraulic appeals board established in RCW 75.20.130.

Bank protection.
Bio-engineering is the preferred method of bank protection where practicable. Bank protection projects shall incorporate mitigation measures as necessary to achieve no-net-loss of productive capacity of fish and shellfish habitat. The following technical provisions shall apply to bank protection projects:

(1) Bank protection work shall be restricted to work necessary to protect eroding banks.

(2) Bank protection material placement waterward of the ordinary high water line shall be restricted to the minimum amount necessary to protect the toe of the bank, or for installation of mitigation features approved by the department.

(3) The toe shall be designed to protect the integrity of bank protection material.

(4) Bank sloping shall be accomplished in a manner that avoids release of overburden material into the water. Overburden material resulting from the project shall be deposited so as not to reenter the water.

(5) Alteration or disturbance of the bank and bank vegetation shall be limited to that necessary to construct the project. All disturbed areas shall be protected from erosion, within seven calendar days of completion of the project, using vegetation or other means. The banks, including riprap areas, shall be revegetated within one year with native or other approved woody species. Vegetative cuttings shall be planted at a maximum interval of three feet (on center), and maintained as necessary for three years to ensure eighty percent survival. Where proposed, planting densities and maintenance requirements for rooted stock will be determined on a site-specific basis. The requirement to plant woody vegetation may be waived for areas where the potential for natural revegetation is adequate, or where other engineering or safety factors preclude them.

(6) Fish habitat components such as logs, stumps, and/or large boulders may be required as part of the bank protection project to mitigate project impacts. These fish habitat components shall be installed according to an approved design to withstand 100-year peak flows.

(7) When rock or other hard materials are approved for bank protection, the following provisions shall apply:

(a) Bank protection material shall be angular rock. The project shall be designed and the rock installed to withstand 100-year peak flows. River gravels shall not be used as exterior armor, except as specifically approved by the department.

(b) Bank protection and filter blanket material shall be placed from the bank or a barge. Dumping onto the bank face shall be permitted only if the toe is established and the material can be confined to the bank face.

Construction of freshwater docks, piers, and floats and the driving or removal of piling.
All pier, dock, float, and piling construction projects shall incorporate mitigation measures as necessary to achieve no-net-loss of productive capacity of fish and shellfish habitat. The following technical provisions shall apply to freshwater dock, pier, and float construction projects and the driving or removal of piling:

(1) Excavation for and placement of the footings and foundation shall be landward of the ordinary high water line unless the construction site is separated from state waters by use of an approved dike, cofferdam, or similar structure.

(2) Alteration or disturbance of the bank and bank vegetation shall be limited to that necessary to construct the project. All disturbed areas shall be protected from erosion, within seven days of completion of the project, using vegetation or other means. The banks shall be revegetated within one year with native or other approved woody species. Vegetative cuttings shall be planted at a maximum interval of three feet (on center), and maintained as necessary for three years to ensure eighty percent survival. Where proposed, planting densities and maintenance requirements for rooted stock will be determined on a site-specific basis. The requirement to plant woody vegetation may be waived for areas where the potential for natural revegetation is adequate, or where other engineering or safety factors preclude them.

(3) Removal of existing or temporary structures shall be accomplished so that the structure and associated material does not reenter the watercourse.

(4) All piling, lumber, or other materials treated with preservatives shall be sufficiently cured to minimize leaching into the water or bed. The use of wood treated with creosote or pentachlorophenol is not allowed in lakes.

(5) Skirting or other structures shall not be constructed around piers, docks, or floats unless specifically approved in the HPA.

(6) Floatation for the structure shall be enclosed and contained, when necessary, to prevent the breakup or loss of the floatation material into the water.

(7) All work operations shall be conducted in such a manner that causes little or no siltation to adjacent areas. If at any time, fish are observed in distress, a fish kill occurs, or water quality problems develop as a result of a pier, dock, float, or piling project, construction operations shall cease and the permittee or authorized agent shall immediately contact the department.

(8) Removal of aquatic vegetation shall be limited to that necessary to gain access to construct the project.

Water crossing structures.
In fish bearing waters, bridges are preferred as water crossing structures by the department in order to ensure free and unimpeded fish passage for adult and juvenile fishes and preserve spawning and rearing habitat. Pier placement waterward of the ordinary high water line shall be avoided, where practicable. Other structures which may be approved, in descending order of preference, include: Temporary culverts, bottomless arch culverts, arch culverts, and round culverts. Corrugated metal culverts are generally preferred over smooth surfaced culverts. Culvert baffles and downstream control weirs are discouraged except to correct fish passage problems at existing structures.

An HPA is required for construction or structural work associated with any bridge structure waterward of or across the ordinary high water line of state waters. An HPA is also required for bridge painting and other maintenance where there is potential for wastage of paint, sandblasting material, sediments, or bridge parts into the water, or where the work, including equipment operation, occurs waterward of the ordinary high water line. Exemptions/5-year permits will be considered if an applicant submits a plan to adhere to practices that meet or exceed the provisions otherwise required by the department. (continued)
