II. Findings of Fact and Findings of Ultimate Fact:
1. The Department received a complete, written application from applicant on July 29, 2022 for the proposed removal-fill activity consisting of upgrades to fish passage facilities at Dexter Dam on the Middle Fork of the Willamette River.
2. The Department circulated the complete application for 30-day public comment period August 10, 2022 to September 08, 2022, to parties including, affected local, state and federal agencies, affected tribal governments, adjacent landowners, and other parties requesting notification.
3. There were no comments that required a response to the Department.
4. Based on all the information in the agency file in this matter, including the complete application, comments received, applicant response to comments, and the agency’s own investigations, the Department concludes as to the determinations in ORS 196.825(1) and (4), OAR 141-085-0565(3), and OAR 141-093-0115:
a. The project described in the permit application and as conditioned in the proposed permit, is consistent with the protection, conservation, and best use of the water resources of this state as specified in ORS 196.600 to 196.905;
b. The project described in the permit application and as conditioned in the proposed permit would not interfere with the paramount policy of this state to preserve the use of its waters for navigation, fishing, and public recreation.
5. Based on all the information in the agency file in this matter, including the complete application, comments received, applicant response to comments, and the agency’s own investigations, the Department concludes, as to the considerations in ORS 196.825(3), OAR 141-085-0565(4), OAR 141-093-0115.
a. The applicant is a public body and the Department has relied upon the public body’s findings as to local public need and local public benefit.
https://secure.sos.state.or.us/oard/viewSingleRule.action?ruleVrsnRsn=15700
b. There is not an identified economic cost to the public if the proposed fill or removal is not accomplished.
c. The application describes no alternatives to the project for which the fill or removal is proposed because the fish facility must be at the current location to pass fish around the dam. There are no practicable alternatives with lesser impact to waters of this state.
d. The application describes no alternative sites for the proposed removal or fill because of the US District Court of Oregon ordered an interim injunction which required certain actions. There are no practicable alternative sites with lesser impact to waters of this state.
e. The proposed project conforms to sound policies of conservation because adverse effects to the aquatic resources have been reduced to the extent practicable and the proposed permit contains operating conditions for best management practices to further minimize adverse effects. No interference with public health and safety was identified in the application evaluation and public review processes.
f. There is not a conflict with existing public uses of the affected waters or adjacent land uses identified in the application evaluation and public review processes.
g. The proposed fill or removal is compatible with the governing comprehensive plan and land use regulations as described in the Land Use Compatibility Statement
h. The proposed fill and removal is not for streambank protection.
i. No permanent adverse effects to aquatic resources are expected, therefore, compensatory mitigation is not required.
III. Conclusions of Law:
Based on the factors laid out in ORS Chapter 196 and OAR Chapter 141, Division 85, including ORS 196.825, OAR 141-085-0565, and OAR 141-093-0115, DSL should approve the permit application as conditioned in the proposed permit.

7. Stormwater Management Approval Required Before Beginning Work: Prior to the start of construction, the permittee must obtain a National Pollution Discharge Elimination System (NPDES) permit from the Oregon Department of Environmental Quality (DEQ), if one is required by DEQ.
General Construction Conditions
8. Water Quality Certification: The Department of Environmental Quality (DEQ) may evaluate this project for a Clean Water Act Section 401 Water Quality Certification (WQC). If the evaluation results in issuance of a Section 401 WQC, that turbidity condition will govern any allowable turbidity exceedance and monitoring requirements.
9. Erosion Control Methods: The following erosion control measures (and others as appropriate) must be installed prior to construction and maintained during and after construction as appropriate, to prevent erosion and minimize movement of soil into waters of this state.
a. All exposed soils must be stabilized during and after construction to prevent erosion and sedimentation.
b. Filter bags, sediment fences, sediment traps or catch basins, leave strips or berms, or other measures must be used to prevent movement of soil into waterways and wetlands.
c. To prevent erosion, use of compost berms, impervious materials or other equally effective methods, must be used to protect soil stockpiled during rain events or when the stockpile site is not moved or reshaped for more than 48 hours.
d. Unless part of the authorized permanent fill, all construction access points through, and staging areas in, riparian and wetland areas must use removable pads or mats to prevent soil compaction. However, in some wetland areas under dry summer conditions, this requirement may be waived upon approval by DSL. At project completion, disturbed areas with soil exposed by construction activities must be stabilized by mulching and native vegetative plantings/seeding. Sterile grass may be used instead of native vegetation for temporary sediment control. If soils are to remain exposed more than seven days after completion of the work, they must be covered with erosion control pads, mats or similar erosion control devices until vegetative stabilization is installed.
e. Where vegetation is used for erosion control on slopes steeper than 2:1, a tackified seed mulch must be used so the seed does not wash away before germination and rooting.
f. Dredged or other excavated material must be placed on upland areas having stable slopes and must be prevented from eroding back into waterways and wetlands.
g. Erosion control measures must be inspected and maintained as necessary to ensure their continued effectiveness until soils become stabilized.
h. All erosion control structures must be removed when the project is complete, and soils are stabilized and vegetated.

Machinery and equipment staging, cleaning, maintenance, refueling, and fuel storage must be at least 150 feet from OHW or HMT and wetlands to prevent contaminates from entering waters of the state.
Refueling is to be confined to a designated area to prevent spillage into waters of this state.
Barges must have containment system to effectively prevent petroleum products or other deleterious material from entering waters of this state. Project-related spills into waters of this state or onto land with a potential to enter waters of this state must be reported to the Oregon Emergency Response System (OERS) at 1-800-452-0311.
11. Archaeological Resources: If any archaeological resources, artifacts or human remains are encountered during construction, all construction activity must immediately cease. The State Historic Preservation Office must be contacted at 503-986-0674. You may be contacted by a Tribal representative if it is determined by an affected Tribe that the project could affect Tribal cultural or archeological resources.
12. Hazards to Recreation, Navigation or Fishing: The activity must be timed so as not to unreasonably interfere with or create a hazard to recreational or commercial navigation or fishing.
13. Operation of Equipment in the Water: Heavy equipment may be positioned below ordinary high water only if the area is isolated from the waterway and aquatic organism salvage is completed.
All machinery operated below ordinary high water (OHW) elevation must use vegetable-based hydraulic fluids, be steam cleaned and inspected for leaks prior to each use, and be diapered to prevent leakage of fuels, oils, or other fluids below OHW elevation. Any equipment found to be leaking fluids must be immediately removed from and kept out of OHW until repaired.
14. Work Area Isolation: The work area must be isolated from the water during construction by using a coffer dam or similar structure in accordance with the work area isolation plan in the application and addenda. All structures and materials used to isolate the work area must be removed immediately following construction and water flow returned to pre-construction conditions.
