Or. Admin. Code § 141-093-0135

Current through Register Vol. 63, No. 11, November 1, 2024

Section 141-093-0135 - General Conditions

Unless otherwise modified by a specific GP or an authorization issued under a GP, the following general conditions apply:

(1) Responsible Party. The person listed on the application as the applicant is responsible for the activities of all contractors or other operators involved in project work covered by the authorization under the GP.

(2) Copy of Authorization Available for Inspection. A copy of the authorization must be available at the work site whenever authorized activities are being conducted.

(3) Site Access Required. Employees of the Department and all authorized representatives must be permitted access to the project area at all reasonable times for the purpose of inspecting work performed under this authorization.

(4) Archeological Resources. If any archeological sites, resources or artifacts are discovered during construction, work must immediately cease and the State Historic Preservation Office must be contacted.

(5) ODFW Fish Passage Requirement. The authorized activity must meet Oregon Department of Fish and Wildlife requirements for fish passage before commencing the project (ORS 509.580 through 509.901 and OAR 635-412-0005 through 635-412-0040).

(6) Hazards to Recreation, Navigation or Fishing. The activity must be timed not to interfere with or create a hazard to recreational or commercial navigation or fishing.

(7) Work Period in Jurisdictional Areas. Fill or removal activities below the Ordinary High Water Line must be conducted when recommended by ODFW, unless otherwise coordinated with Oregon Department of Fish and Wildlife and approved in writing by DSL. Work is prohibited when fish eggs are present within the reach where the authorized activities are being conducted.

(8) Pre-Construction Resource Area Fencing or Flagging. Prior to any site grading, the boundaries of any avoided wetlands, waterways and riparian areas adjacent to the project site must be surrounded by noticeable construction fencing or flagging. There will be no vegetation removal or heavy equipment within marked areas. The marked areas must be maintained during construction of the project and be removed immediately upon project completion.

(9) Erosion Control Methods. The following erosion control measures must be installed at the construction site before construction and maintained during and after construction to prevent erosion and minimize movement of soil into waters of this state:

(a) All exposed soils must be stabilized during and after construction in order 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 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 or seeding. Sterile grass may be used instead of native vegetation for temporary sediment control if native vegetation is unavailable. If soils are to remain exposed for more than seven days after completion of the permitted 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, 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; and

(h) All erosion control structures must be removed when the project is complete and soils are stabilized and vegetated.

(10) Hazardous, Toxic, and Waste Material Handling. Petroleum products, chemicals, fresh cement, sandblasted material and chipped paint, wood treated with leachable preservatives or other deleterious waste materials must not be allowed to enter waters of this state. Machinery refueling is to occur at least 150 feet from waters of this state and confined in a designated area to prevent spillage into waters of this state. Barges must have a 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) Raising or Redirecting Water. The project must not cause water to rise or be redirected and result in damage to structures or property.

(12) Waste Disposal. Old piling and other waste material generated by the project must be disposed of in an appropriate disposal facility. There must be no temporary storage of piling or other waste material below top of bank, in wetlands; in a Federal Emergency Management Administration designated floodway, or in an area historically subject to landslides.

(13) DSL May Halt or Modify. DSL retains the authority to temporarily halt or modify the project in case of unforeseen damage to natural resources.

(14) Spoil Disposal. Spoil materials, not authorized used in the project for placement in waters of this state, must be placed in an upland location. Spoil materials used in the project must be included in the cumulative removal-fill calculation for the activity.

(15) Additional Conditions. The Department may impose additional conditions, if necessary, to eliminate and reduce the reasonably expected adverse impacts of a project to waters of this state.
