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 through 220-110-338 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.

You and your authorized agent, if one is acting for you, must sign and date the application.
(4) The department shall grant or deny approval within forty-five calendar days of the receipt of a complete written application. The department shall strive to issue HPAs in less than thirty days. The forty-five day requirement shall be suspended if:
(a) The site is physically inaccessible for inspection;
(b) You or your authorized agent, if one is acting for you, remains unavailable or unable to arrange for a timely field evaluation of the proposed project after ten working days of the department's receipt of the application;
(c) You or your authorized agent, if one is acting for you, requests a delay;
(d) The department is issuing a permit for a storm water discharge and is complying with the requirements of RCW 77.55.161 (3)(b); or
(e) The department is reviewing the application as part of a multiagency permit streamlining effort and all participating permitting agencies and the permit applicant agree to an extended timeline longer than forty-five calendar days.
(5) Immediately upon determination that the forty-five day period is suspended, the department shall notify the applicant in writing of the reasons for the delay.
(6) The department or the county legislative authority may determine an imminent danger exists. The county legislative authority shall notify the department, in writing, if it determines that an imminent danger exists. In cases of imminent danger, the department shall issue an expedited written permit, upon request, for work to remove any obstructions, repair existing structures, restore banks, protect fish resources, or protect property.
(7) The department may issue an expedited written HPA in those instances where normal processing would result in significant hardship for the applicant, or unacceptable environmental damage would occur.
(8) Expedited HPA requests require a complete written application and shall take precedence over other nonemergency applications. These will be issued within fifteen calendar days of receipt of a complete written application. The provisions of the State Environmental Policy Act, chapter 43.21C RCW, are not required for expedited written HPAs.
(9) The county legislative authority or the department may declare an emergency or continue an existing declaration of an emergency where there is an immediate threat to life, the public, property, or of environmental degradation. Upon the declaration of an emergency, the department shall grant verbal approval immediately upon request for a stream crossing, or work to remove any obstructions, repair existing obstructions, restore streambanks, protect fish life, or protect property threatened by the stream or a change in the stream flow. The verbal approval shall be obtained prior to commencing emergency work and the department must issue a written HPA reflecting the conditions of the verbal approval within thirty days. The provisions of the State Environmental Policy Act, chapter 43.21C RCW, are not required for emergency HPAs.
(10) The department may accept written or verbal requests for time extensions, renewals, or alterations of an existing HPA. The request must be processed within forty-five calendar days of receipt of the request. Approvals of such requests shall be in writing. Transfer of an HPA to a new permittee requires written request by the original permittee or their authorized agent, if one is acting for the permittee, and such request shall include the HPA number.

The new permittee shall not conduct any project activities until the department has issued approval.
(11) Each HPA is usually specific to a watercourse, stating the exact location of the project site, and usually consists of general, technical, and special provisions.
(12) The written HPA, or clear reproduction, shall be on the project site when work is being conducted and shall be immediately available for inspection.
(13) The department may grant HPAs for a period of up to five years. Permittees shall demonstrate substantial progress on construction of that portion of the project relating to the HPA within two years of the date of issuance. The following types of HPAs issued under RCW 77.55.021 shall remain in effect without the need for periodic renewal, provided the permittee notifies the department before commencing work each year:
(a) Work of a seasonal nature that diverts water for irrigation or stock watering purposes; and
(b) Stream-bank 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 floodwaters by themselves do not constitute a problem that requires an HPA.
(14) An HPA 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.
(15) Protection of fish life shall be the only grounds upon which the department may deny or condition an HPA.
(16) The department may place specific time limitations on project activities in HPAs to protect fish life.
(17) 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.

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.
Water crossing structure 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 water crossing structures:
(1) Bridge construction.
(a) Excavation for and placement of the foundation and superstructure shall be outside the ordinary high water line unless the construction site is separated from waters of the state by use of an approved dike, cofferdam, or similar structure.
(b) The bridge structure or stringers shall be placed in a manner to minimize damage to the bed.
(c) Alteration or disturbance of bank or 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 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.
(d) Removal of existing or temporary structures shall be accomplished so that the structure and associated material does not enter the watercourse.
(e) The bridge shall be constructed, according to the approved design, to pass the 100-year peak flow with consideration of debris likely to be encountered. Exception shall be granted if applicant provides hydrologic or other information that supports alternative design criteria.
(f) Wastewater from project activities and water removed from within the work area shall be routed to an area landward of the ordinary high water line to allow removal of fine sediment and other contaminants prior to being discharged to state waters.
(g) Structures containing concrete shall be sufficiently cured prior to contact with water to avoid leaching.
(h) Abutments, piers, piling, sills, approach fills, etc., shall not constrict the flow so as to cause any appreciable increase (not to exceed .2 feet) in backwater elevation (calculated at the 100-year flood) or channel wide scour and shall be aligned to cause the least effect on the hydraulics of the watercourse.
(i) Riprap materials used for structure protection shall be angular rock and the placement shall be installed according to an approved design to withstand the 100-year peak flow.
(2) Temporary culvert installation.
The allowable placement of temporary culverts and time limitations shall be determined by the department, based on the specific fish resources of concern at the proposed location of the culvert.
(a) Where fish passage is a concern, temporary culverts shall be installed according to an approved design to provide adequate fish passage. In these cases, the temporary culvert installation shall meet the fish passage design criteria in Table 1 in subsection (3) of this section.
(b) Where culverts are left in place during the period of September 30 to June 15, the culvert shall be designed to maintain structural integrity to the 100-year peak flow with consideration of the debris loading likely to be encountered.
(c) Where culverts are left in place during the period June 16 to September 30, the culvert shall be designed to maintain structural integrity at a peak flow expected to occur once in 100 years during the season of installation.
(d) Disturbance of the bed and banks shall be limited to that necessary to place the culvert and any required channel modification associated with it. Affected bed and bank areas outside the culvert shall be restored to preproject condition following installation of the culvert.
(e) The culvert shall be installed in the dry, or in isolation from stream flow by the installation of a bypass flume or culvert, or by pumping the stream flow around the work area. Exception may be granted if siltation or turbidity is reduced by installing the culvert in the flowing stream. The bypass reach shall be limited to the minimum distance necessary to complete the project. Fish stranded in the bypass reach shall be safely removed to the flowing stream.
(f) Wastewater, from project activities and dewatering, shall be routed to an area outside the ordinary high water line to allow removal of fine sediment and other contaminants prior to being discharged to state waters.
(g) Imported fill which will remain in the stream after culvert removal shall consist of clean rounded gravel ranging in size from one-quarter to three inches in diameter. The use of angular rock may be approved from June 16 to September 30, where rounded rock is unavailable. Angular rock shall be removed from the watercourse and the site restored to preproject conditions upon removal of the temporary culvert.
(h) The culvert and fill shall be removed, and the disturbed bed and bank areas shall be reshaped to preproject configuration. 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 need to be considered.
(i) The temporary culvert shall be removed and the approaches shall be blocked to vehicular traffic prior to the expiration of the HPA.
(j) Temporary culverts may not be left in place for more than two years from the date of issuance of the HPA.
(3) Permanent culvert installation.
(a) In fish bearing waters or waters upstream of a fish passage barrier (which can reasonably be expected to be corrected, and if corrected, fish presence would be reestablished), culverts shall be designed and installed so as not to impede fish passage. Culverts shall only be approved for installation in spawning areas where full replacement of impacted habitat is provided by the applicant.
(b) To facilitate fish passage, culverts shall be designed to the following standards:
(i) Culverts may be approved for placement in small streams if placed on a flat gradient with the bottom of the culvert placed below the level of the streambed a minimum of twenty percent of the culvert diameter for round culverts, or twenty percent of the vertical rise for elliptical culverts (this depth consideration does not apply within bottomless culverts). Footings of bottomless culverts shall be buried sufficiently deep so they will not become exposed by scour within the culvert. The twenty percent placement below the streambed shall be measured at the culvert outlet. The culvert width at the bed, or footing width, shall be equal to or greater than the average width of the bed of the stream.
(ii) Where culvert placement is not feasible as described in (b)(i) of this subsection, the culvert design shall include the elements in (b)(ii)(A) through (E) of this subsection:
(A) Water depth at any location within culverts as installed and without a natural bed shall not be less than that identified in Table 1. The low flow design, to be used to determine the minimum depth of flow in the culvert, is the two-year seven-day low flow discharge for the subject basin or ninety-five percent exceedance flow for migration months of the fish species of concern. Where flow information is unavailable for the drainage in which the project will be conducted, calibrated flows from comparable gauged drainages may be used, or the depth may be determined using the installed no-flow condition.
(B) The high flow design discharge, used to determine maximum velocity in the culvert (see Table 1), is the flow that is not exceeded more than ten percent of the time during the months of adult fish migration. The two-year peak flood flow may be used where stream flow data are unavailable.
(C) The hydraulic drop is the abrupt drop in water surface measured at any point within or at the outlet of a culvert. The maximum hydraulic drop criteria must be satisfied at all flows between the low and high flow design criteria.
(D) The bottom of the culvert shall be placed below the natural channel grade a minimum of twenty percent of the culvert diameter for round culverts, or twenty percent of the vertical rise for elliptical culverts (this depth consideration does not apply within bottomless culverts). The downstream bed elevation, used for hydraulic calculations and culvert placement in relation to bed elevation, shall be taken at a point downstream at least four times the average width of the stream (this point need not exceed twenty-five feet from the downstream end of the culvert). The culvert capacity for flood design flow shall be determined by using the remaining capacity of the culvert.

(F) Culvert design shall include consideration of flood capacity for current conditions and future changes likely to be encountered within the stream channel, and debris and bedload passage.
(c) Culverts shall be installed according to an approved design to maintain structural integrity to the 100-year peak flow with consideration of the debris loading likely to be encountered. Exception may be granted if the applicant provides justification for a different level or a design that routes that flow past the culvert without jeopardizing the culvert or associated fill.
(d) Disturbance of the bed and banks shall be limited to that necessary to place the culvert and any required channel modification associated with it. Affected bed and bank areas outside the culvert and associated fill shall be restored to preproject configuration following installation of the culvert, and 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.
(e) Fill associated with the culvert installation shall be protected from erosion to the 100-year peak flow.
(f) Culverts shall be designed and installed to avoid inlet scouring and shall be designed in a manner to prevent erosion of streambanks downstream of the project.
(g) Where fish passage criteria are required, the culvert facility shall be maintained by the owner(s), such that fish passage design criteria in Table 1 are not exceeded. If the structure becomes a hindrance to fish passage, the owner shall be responsible for obtaining a HPA and providing prompt repair.
(h) The culvert shall be installed in the dry or in isolation from the stream flow by the installation of a bypass flume or culvert, or by pumping the stream flow around the work area. Exception may be granted if siltation or turbidity is reduced by installing the culvert in the flowing stream. The bypass reach shall be limited to the minimum distance necessary to complete the project. Fish stranded in the bypass reach shall be safely removed to the flowing stream.
(i) Wastewater, from project activities and dewatering, shall be routed to an area outside the ordinary high water line to allow removal of fine sediment and other contaminants prior to being discharged to state waters.

Channel change/realignment.

Channel changes/realignments are generally discouraged, and shall only be approved where the applicant can demonstrate benefits or lack of adverse impact to fish life. Channel change/realignment 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 channel change and channel realignment projects:
When approved, a channel change may occur provided:
(1) Permanent new channels shall, at a minimum, be similar in length, width, depth, flood plain configuration, and gradient, as the old channel. The new channel shall incorporate fish habitat components, bed materials, meander configuration, and native or other approved vegetation equivalent to or greater than that which previously existed in the old channel.
(2) During construction, the new channel shall be isolated from the flowing stream by plugs at the upstream and downstream ends of the new channel.
(3) Before water is diverted into a permanent new channel, the applicant shall complete the following actions:
(a) Approved fish habitat components, bed materials and bank protection to prevent erosion shall be in place.
(b) Approved fish habitat components shall be installed according to an approved design to withstand the 100-year peak flows.
(4) 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.
(5) Diversion of flow into a new channel shall be accomplished by: (a) First removing the downstream plug; (b) removing the upstream plug; and (c) closing the upstream end of the old channel.
(6) Filling of the old channel shall begin from the upstream closure and the fill material shall be compacted. Water discharging from the fill shall not adversely impact fish life.
(7) The angle of the structure used to divert the water into the new channel shall allow a smooth transition of water flow.
(8) If fish may be adversely impacted as a result of this project, the permittee will be required to capture and safely move food fish, game fish or other fish life (at the discretion of the department) to the nearest free-flowing water. The permittee may request the department to assist in capturing and safely moving fish life from the job site to free-flowing water, and assistance may be granted if personnel are available.

Integration of hydraulic project approvals and forest practices applications.

(1) Description. In 1999, the Forests and Fish Report and Engrossed Substitute House Bill 2091, which amended the Forest Practices Act, chapter 76.09 RCW, envisioned a more integrated approach to permitting hydraulic projects that also require forest practices applications (FPAs). In May 2001, the forest practices board adopted permanent forest practices rules in Title 222 WAC, which incorporated fish protection measures normally included in hydraulic project approvals (HPAs) for projects in nonfish-bearing waters.
In April 2012, the legislature, through Second Engrossed Substitute Senate Bill 6406, amended the Forest Practices Act in chapter 76.09 RCW and the hydraulic code statutes in chapter 77.55 RCW. The amendment requires integration of hydraulic code rule fish protection standards (Title 220 WAC) into the forest practices rules for hydraulic projects in fish-bearing waters on forest land. As codified in RCW 77.55.361 and 76.09.040, the requirements of the hydraulic code rules will no longer apply to any forest practices hydraulic project as soon as fish protection standards have been integrated into the forest practices rules, and technical guidance has been developed and approved for inclusion in the Forest Practices Board Manual. Thereafter, forest practices hydraulic projects will be regulated under forest practices rules. The amended statutes also include a requirement that the department of fish and wildlife (department) adopt rules establishing the procedures for the concurrence review process. This process is outlined in subsection (3) of this section.
(2) General review and comment on forest practices hydraulic projects.
(a) The department may review and provide comments on any FPA.
(b) For FPAs that include a forest practices hydraulic project involving fish-bearing waters or shorelines of the state, the department must review the forest practices hydraulic projects and either provide comments to the department of natural resources (DNR), or document that the review has occurred without the need for comments. Prior to commenting, the department will strive to communicate with the applicant regarding any concerns relating to consistency with fish protection standards. The department will also strive to maintain communications with DNR as concerns arise and to inform DNR of communications with applicants.
(c) The department will encourage forest landowners to consult with department biologists, including site visits as needed, prior to submitting an FPA containing a hydraulic project. This will help ensure that project design plans and specifications meet fish protection standards. Preapplication collaboration with the department will result in more efficient and successful outcomes for forest landowners and their proposed hydraulic projects.
In addition to the general review and comment process for forest practices hydraulic projects described in this subsection, hydraulic projects meeting the criteria described in subsection (3)(a) of this section will follow the concurrence review process.
(3) Concurrence review process.
(a) The department must review forest practices hydraulic projects meeting the following criteria and provide written comments to DNR on the project's ability to meet fish protection standards:
(i) Culvert installation or replacement, and repair at or below the bankfull width, as that term is defined in WAC 222-16-010 on July 10, 2012, in fish-bearing rivers and streams that exceed five percent gradient;
(ii) Bridge construction or replacement, and repair at or below the bankfull width, of fish-bearing unconfined streams; or
(iii) Fill within the flood level - 100 year, as that term is defined in WAC 222-16-010 on July 10, 2012, of fish-bearing unconfined streams.
(b) After the department receives notification from DNR that a FPA includes one or more hydraulic projects meeting the criteria in (a) of this subsection, the department has thirty days to review the forest practices hydraulic project(s) for consistency with fish protection standards.
(c) Within five business days following notification from DNR, or as soon as possible thereafter, the department will determine whether all information, needed for assessing the hydraulic project's consistency with fish protection standards, is included in the application.
(d) If information is missing, the department will immediately contact the applicant to request the missing information. The department will also provide written notification to DNR, indicating that specific information is missing and that the applicant has been notified. The department may issue a nonconcurrence on a proposed project if the applicant fails to provide missing information in a timely manner so that the department can complete its review within the required thirty-day time frame.
(e) If, during the thirty-day concurrence review period, the department determines that a forest practices hydraulic project may not be consistent with fish protection standards, the department will attempt to work with the applicant to modify the proposed project. The department will strive to include DNR participation on site visits with the applicant as needed.
(f) The department must provide written notification of concurrence or nonconcurrence to DNR within the thirty-day review period, stating whether or not the hydraulic project is consistent with fish protection standards. As part of the written notification to DNR, the department must provide information about the outcomes of any meetings with the applicant, including agreements or disagreements, any missing information requested, and any proposed changes needed to meet fish protection standards.
(g) The department will recommend that DNR deny the FPA when efforts described in (e) of this subsection have not resulted in a successful outcome, the project will result in direct or indirect harm to fish life, and adequate mitigation cannot be assured by modifying the hydraulic project proposal or by DNR's agreement to add appropriate provisions to the FPA.

(c) Disturbance of the bed as a result of the plowing operation shall be limited to the amount necessary to complete the project.
(5) Trenches shall be backfilled with approved materials and the bed shall be returned to preproject condition.
(6) Excess spoils shall be disposed of so as not to reenter the watercourse.
(7) The conduit approach trench shall be isolated from the watercourse until laying of the conduit across the watercourse takes place.
(8) Alteration or disturbance of the banks 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.

Gravel removal.

Gravel removal 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 gravel removal projects:
(1) Gravel removal from a watercourse shall be limited to removal from exposed bars and shall not result in a lowering, over time, of the average channel cross-section profile through the project area or downstream. Additional removal of bed material, including removal from wetted portions of the channel, may be authorized where the project is an integral part of a comprehensive flood control plan approved by the department.
(2) An "excavation line" shall be established. "Excavation line" means a line on the dry bed, at or parallel to the water's edge, the distance from the water's edge to be determined by the department on a site-specific basis. The excavation line may change with water level fluctuations.
(3) An "excavation zone" shall be defined as the area between the "excavation line" and the bank or the center of the bar. The "excavation zone" shall be identified by boundary markers placed by the applicant and approved by the department prior to the commencement of gravel removal.
(4) Excavation shall begin at the excavation line and proceed toward the bank or the center of the bar, perpendicular to the alignment of the watercourse.
(5) Bed material shall not be removed from the water side of the excavation line.
(6) Equipment shall not enter or operate within the wetted perimeter of the watercourse.
(7) Gravel may be removed within the excavation zone from a point beginning at the excavation line and progressing upward toward the bank or the center of the bar on a minimum two percent gradient. It may be necessary to survey the excavation zone upon completion of the gravel removal operation to ensure the two percent gradient is maintained and that no depressions exist. When required the survey shall be made at the applicant's expense.
(8) Preproject and postproject channel cross-section surveys shall be required for gravel removal projects for commercial purposes, and may be required as part of a comprehensive flood control plan approved by the department. The cross-sections shall be referenced vertically to a permanent bench mark and horizontally to a permanent base line, and shall be done perpendicular to the high flow channel every one hundred feet through the project area and at cross-sections upstream and downstream at adjacent channel riffles. The preproject survey information shall be submitted to the department at the time of application for HPA, and the postproject survey shall be submitted to the department within ninety days of completion of removal of gravel or the expiration date of the HPA, whichever occurs first.
(9) At the end of each work day the excavation zone shall not contain pits, or potholes, or depressions that may trap fish as a result of fluctuation in water levels.
(10) Stockpiling of material waterward of the ordinary high water line, after the initial bed disturbance, shall be limited to avoid impacts to fish life. If stockpiling is approved waterward of the ordinary high water line, the material shall be completely removed prior to the onset of fish spawning in the vicinity or the typical onset of increasing stream flows. Timing restrictions shall be determined on a site-specific basis. If the water level rises and makes contact with stockpiles, further operation of equipment or removal of the stockpiles shall not proceed unless authorized under a separate HPA issued by the department.
(11) The upstream end of the gravel bar shall be left undisturbed to maintain watercourse stability waterward of the ordinary high water line.
(12) Large woody material shall be retained waterward of the ordinary high water line and repositioned within the watercourse. Other debris shall be disposed of so as not to reenter the watercourse.
(13) Gravel washing or crushing operations shall not take place waterward of the ordinary high water line.
(14) Alteration or disturbance of the banks and bank vegetation shall be limited to that necessary to access the excavation zone. 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.
(15) Equipment shall be inspected, cleaned, and maintained to prevent loss of petroleum products waterward of the ordinary high water line.
(16) The department shall be notified at least five working days before the start of actual gravel removal, and upon project completion to allow for compliance inspection.

Large woody material removal or repositioning.

Large woody material removal or repositioning 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 large woody material removal or repositioning:
(1) Large woody material removal from watercourses shall only be approved where necessary to address safety considerations, or its removal would not diminish the fish habitat quality of the watercourse. The department may approve the repositioning of large woody material within the watercourse to protect life and property or as needed to conduct a hydraulic project. Repositioned large woody material shall be placed or anchored to provide stable, functional fish habitat.
(2) Large woody material removal shall be conducted by equipment stationed on the bank, bridge, or other approved structure.
(3) Unless otherwise authorized, large woody material shall be suspended during its removal so no portion of the large woody material or limbs can damage the bed or banks. Yarding corridors or full suspension shall be required to avoid damage to riparian vegetation. It may be necessary to cut the large woody material in place, to a size that allows suspension during removal.
(4) Where large woody material cannot be suspended above the bed and banks, skid logs or similar methods shall be used to avoid bank damage. Upon completion of the yarding operation, skid logs shall be removed in a manner that avoids damage to streambanks and vegetation, and the bank shall be restored to preproject condition.
(5) Smaller limb and bark debris associated with the large woody material shall be removed and disposed of so as not to reenter the watercourse.
(6) Large woody material embedded in a bank or bed shall be left undisturbed and intact except where authorized for removal.
(7) Large woody material removal or repositioning shall be accomplished in a manner which minimizes the release of bedload, logs, or debris downstream.
(8) Depressions created in gravel bars shall be filled, smoothed over, and sloped upwards toward the bank on a minimum two percent gradient.

220-110-160
Felling and yarding of timber.

The following technical provisions shall apply to any felling and yarding of timber for which an HPA is required (see WAC 220-110-020). Timber felling and yarding projects requiring an HPA shall incorporate mitigation measures as necessary to achieve no-net-loss of productive capacity of fish and shellfish habitat.
(1) Trees shall not be felled into or across a watercourse, with identifiable bed or banks, except where authorized in special provisions of an HPA.
(2) Trees or logs which enter a watercourse, with identifiable bed or banks, during felling or yarding shall remain where they enter unless parts or all of the trees or logs are specifically authorized to be removed.
(3) Logs transported across a watercourse, with identifiable bed or banks, shall be suspended so no portion of the logs or limbs can enter the watercourse or damage the bed and banks. Yarding corridors or full suspension shall be required to prevent damage to riparian vegetation.
(4) Cable tailholds may be placed over watercourses, with identifiable bed or banks, provided the number of yarding roads is kept to a minimum. When changing roads, the cable shall be moved around or over the riparian vegetation to avoid damage to the vegetation.
(5) If limbs or other small debris enter the watercourse, with identifiable bed or banks, as a result of felling and yarding of timber, they shall be removed concurrently with each change in yarding road or within seventy-two hours after entry into the watercourse and placed outside the 50-year flood plain. Limbs or other small debris shall be removed from dry watercourses prior to the normal onset of high flows. Large woody material which was in place prior to felling and yarding of timber shall not be disturbed.
(6) Precautions shall be taken to minimize the release of sediment to waters downstream from the felling or yarding activity. Sediment control devices, including, but not limited to, straw bales and filter fabric check dams, shall be used as necessary to avoid the release of sediment downstream. Accumulated sediment shall be removed from above check dams prior to their removal. The requirement to provide sediment control may be waived where adequate protection is provided through seasonal restriction of operations.
(7) There shall be no skidding or ground lead yarding or equipment operation within flowing waters in channels with defined bed or banks.

220-110-180
Pond construction.

Pond 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 pond construction projects connected to a watercourse:
(1) Ponds shall not be constructed within the watercourse.
(2) Ponds shall be designed, constructed, and screened to prevent the entry of fish unless the pond will provide beneficial habitat, as determined by the department, in which case free and unrestricted access shall be provided.
(3) Pond return flow shall be located to minimize the length of the bypass reach unless the bypass reach is intended to enhance fish life or habitat.
(4) Pond construction activities involving diversion of state waters shall be dependent upon first obtaining a water right. This requirement does not apply to construction of storm water pond facilities landward of the ordinary high water line.
(5) The work area shall be isolated from the watercourse during construction of the pond, the diversion system, and the return flow system.
(6) Prior to the initial filling, 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.
(7) Ponds shall be designed and constructed so the outflow temperature is not harmful to fish life.

220-110-190
Water diversions.

A written HPA is not required for emergency water diversions during emergency fire response. The department shall be notified prior to the diversion, when possible. When prior notification is not possible, the department shall be notified within twenty-four hours of the diversion. The hydraulic code cannot be used to limit the amount or timing of water diverted under a water right. However, construction of structures or placement of devices or other work within waters of the state which will use, divert, obstruct, or change the natural flow or bed of any of the salt or fresh waters of the state, or that will utilize any of the waters of the state in order to divert water pursuant to a water right, requires an HPA. Regulation of water flow from a permanent irrigation structure by operating valves, or manipulating stop logs, check boards or head boards, does not require an HPA. Any hydraulic project activity related to a change in the manner or location of water diversion will require an HPA modification.
Persons who have gravel berm dams as the method of diversion permitted by the department prior to January 1994 shall be allowed to continue to do so consistent with the provisions of an HPA. The department can, however, condition the approval of gravel berms.
Construction or maintenance of fish screens or guards requiring use of equipment requires a written HPA. Installation of suction hoses or cleaning, adjusting, operating, and maintaining existing irrigation or stock water diversion structures including intakes or screens without the use of equipment, may be accomplished without first securing a written HPA. For these activities, compliance with the provisions of the latest edition of the Irrigation and Fish pamphlet issued by the department is required. The pamphlet shall be on-site and serve as the HPA. If a fish kill occurs or fish are observed in distress, the project activity shall cease and the department shall be notified immediately.
The following technical provisions shall apply to water diversions:
(1) Gravel berm dams shall be constructed of gravels available on site waterward of the ordinary high water line, or of clean round gravel transported to the site. Bed disturbance shall be limited to the minimum necessary to achieve the provisions of the water right. No dirt from outside the ordinary high water line shall be used to seal the dam and no logs or woody material waterward of the ordinary high water line may be utilized for construction of the dam, unless specifically authorized.
(2) Logs and large woody material may be relocated waterward of the ordinary high water line, if they block water flow into the ditch or inhibit construction.
(3) As long as the applicant or permittee can divert enough water to satisfy the water right, the diversion dam shall be constructed so that it does not hinder upstream and downstream adult and juvenile fish passage. If passage problems develop, department personnel may, after consultation, require modification of the gravel berm dam.
(4) At pump stations, screens and headgate areas, a backhoe or suction dredge may be used to remove accumulated silts and gravel from the pumping sump. Material removed shall be placed so it will not reenter state waters.
(6) Diversion canals shall be maintained (sediment and debris removal) to provide maximum hydraulic gradient in the diversion canal in order to minimize the need for work within the natural watercourse.
(7) The exercise of project activity associated with diversion of state waters shall be dependent upon first obtaining a water right.

Mineral prospecting.

(1) WAC 220-110-201 through 220-110-206 set forth the rules necessary to protect fish life that apply to mineral prospecting and placer mining projects. A copy of the current Gold and Fish pamphlet is available from the department, and it contains the rules which you must follow when mineral prospecting under its authority.
(2) Alternatively, you may request exceptions to the Gold and Fish pamphlet by applying for an individual written HPA as indicated in WAC 220-110-031. An HPA 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. The department may apply saltwater provisions to written HPAs for tidally influenced areas upstream of river mouths and the mainstem Columbia River downstream of Bonneville Dam where applicable.
(3) Nothing in these rules relieves a person of the duty to obtain landowner permission and any other necessary permits before conducting any mineral prospecting activity.

(a) At any location if you use pans; spiral wheels; or sluices, concentrators, mini rocker boxes, and mini high-bankers with riffle areas totaling three square feet or less, including ganged equipment. You must classify the aggregate at the excavation site prior to processing with this equipment within the wetted perimeter or frequent scour zone.
(b) Only at an upland location landward of the frequent scour zone if you use power sluice/suction dredge combinations; high-bankers; power sluices; or rocker boxes. You may not allow tailings or wastewater to enter the wetted perimeter or frequent scour zone.
(c) Within the wetted perimeter or frequent scour zone with a sluice with a riffle area greater than three square feet. You must classify the aggregate at the excavation site prior to processing with a sluice with a riffle area exceeding three square feet.
(20) You may use pressurized water only for crevicing or for redistributing dredge tailings within the wetted perimeter. No other pressurized water use is permitted.
(21) You may conduct crevicing in the wetted perimeter, in the frequent scour zone, or landward of the frequent scour zone. The hose connecting fittings of pressurized water tools used for crevicing may not have an inside diameter larger than three-quarters of an inch. If you crevice landward of the frequent scour zone, you may not discharge sediment or wastewater to the wetted perimeter or the frequent scour zone.
(22) You must avoid areas containing live freshwater mussels. If you encounter live mussels during excavation, you must relocate your operations.
(23) You may not disturb redds. If you observe or encounter redds, or actively spawning fish when collecting or processing aggregate, you must relocate your operations.
(24) If at any time, as a result of project activities, you observe a fish kill or fish life in distress, you must immediately cease operations and notify the Washington department of fish and wildlife, and the Washington military department emergency management division of the problem. You may not resume work until the Washington department of fish and wildlife gives approval. The Washington department of fish and wildlife may require additional measures to mitigate the prospecting impacts.
