Department of State Lands, Chapter 141

Rule Caption: General Permit for Impacts to Vernal Pool Wetlands, Revisions to the Rules for General Permits.

Adm. Order No.: DSL 1-2012

Filed with Sec. of State: 3-14-2012

Certified to be Effective: 4-1-12

Notice Publication Date: 9-1-2011

Rules Adopted: 141-093-0180, 141-093-0185, 141-093-0187, 141-093-0190, 141-093-0195, 141-093-0200, 141-093-0205, 141-093-0215

Rules Amended: 141-093-0107, 141-093-0115, 141-093-0135

Subject: In November 2009, after six years of extensive public involvement and interagency coordination, DSL approved a General Permit for Removal-Fill and Mitigation of Impacts to Vernal Pool Wetlands in Jackson County (Vernal Pool GP). The Vernal Pool GP was developed in coordination with the U.S. Army Corps of Engineers and the U.S. Fish and Wildlife Service to address endangered species associated with vernal pools. Through this rulemaking we will finalize the Vernal Pool GP to create a new permit instrument that is predictable, timely, and consistent with the regional planning effort for vernal pools. The revisions to the existing Division 93 rules are necessary to accommodate the new Vernal Pool GP.

 The Vernal Pool GP provides an expedited process (55 days) for permitting impacts to vernal pool wetlands located in Jackson County. The rules describe the standards for mitigation for those impacts that are consistent with the standards required to address the Endangered Species Act (administered by the U.S. Fish and Wildlife Service) and the Clean Water Act (administered by the U.S. Army Corps of Engineers).

Completeness and Eligibility Review for Authorizing Projects under a GP

(1) Initial Review. The Department will review the application within 15 calendar days (unless otherwise stated in the administrative rules for a specific GP), of agency receipt of the application to determine whether the application is complete and the project is eligible for a GP.

(a) Complete and Eligible Application. A complete application is one that contains all the information required in the Department’s application. An eligible project is one that meets the eligibility requirements, activity-specific application requirements and authorized activities listed under the GP.

(b) Incomplete Application Notification. If the Department determines that the application is incomplete or deficient, the Department will notify the applicant in writing and list the missing or deficient information. The applicant may resubmit the entire amended package for reconsideration within 120 calendar days from date of the Department’s notice, unless instructed by the Department to do otherwise. Submission of a new or amended application package starts a new initial review period.

(c) Ineligible Projects. If the review of the application results in a determination that the project is ineligible for a GP, the applicant will be notified and informed of the reason for ineligibility. The applicant may then either revise the project and resubmit the application for reconsideration or apply for an Individual Permit under OAR 141-085 within 120 calendar days from date of agency determination.

(2) Timeframe for Resubmittal. If a revised application is not resubmitted within 120 calendar days of an incompleteness or ineligibility determination, the Department may administratively close the application. If the Department closes the file under this circumstance, the Department will retain the application fee. A subsequent application for the same or similar project will require payment of an application fee.

Department Determinations and Considerations in Evaluating Applications to Authorize Projects under a GP

(1) Departmental Final Review. The Department will evaluate the information provided in the application, conduct its own investigation, and consider the comments submitted during the public review process to determine whether or not to issue an authorization under a GP. The Department will render a decision within 40 calendar days of receipt of a complete application, unless otherwise stated in the administrative rules for a specific GP.

(2) Extension of Decision Deadline. The applicant may request additional time to respond to comments or to satisfy other requirements. The applicant and the Department may agree to extend the timeline for making a final authorization decision. If no agreement is reached, the Department will make a final authorization decision within the original time period specified in these rules.

(3) Effective Date of Review Standards. The Department may consider only standards and criteria in effect on the date the Department receives the complete application or renewal request.

(4) Department Determinations. The Department will issue an authorization under a GP if it determines the project described in the application:

(a) Has independent utility;

(b) Is consistent with the protection, conservation and best use of the water resources of this state as specified in ORS 196.600 through 196.990;

(c) Would not unreasonably interfere with the paramount policy of this state to preserve the use of its waters for navigation, fishing and public recreation, when project is on state-owned lands; and

(d) Meets the purpose and eligibility requirements in the GP.

(5) Department Considerations. In determining whether to issue an authorization under a GP, the Department will consider all of the following:

(a) The public need for the proposed fill or removal and the social, economic and other public benefits likely to result from the proposed fill or removal. When the applicant for an authorization under a GP is a public body, the Department may accept and rely on the public body’s findings as to local public need and local public benefit;

(b) The economic cost to the public if the proposed fill or removal is not accomplished;

(c) The availability of alternatives to the project for which the fill or removal is proposed;

(d) The availability of alternative sites for the proposed fill or removal;

(e) Whether the proposed fill or removal conforms to sound policies of conservation and would not interfere with public health and safety;

(f) Whether the proposed fill or removal is in conformance with existing public uses of the waters and with uses designated for adjacent land in an acknowledged comprehensive plan and land use regulations;

(g) Whether the proposed fill or removal is compatible with the acknowledged comprehensive plan and land use regulations for the area where the proposed fill or removal is to take place or can be conditioned on a future local approval to meet this criterion;

(h) Whether the proposed fill or removal is for stream bank protection; and

(i) Whether the applicant has provided all practicable mitigation to reduce the adverse effects of the proposed fill or removal in the manner set forth in ORS 196.800.

(6) Alternatives Analysis. The applicant bears the burden of providing the Department with the alternatives analysis used to derive the practicable alternative that has the least reasonably expected adverse impacts on waters of this state. The alternatives analysis must provide the Department all the underlying information necessary to support its considerations under section (5) of this rule.

(7) Fills in an Estuary for Non-Water Dependent Use. A “substantial fill” in an estuary is any amount of fill regulated by the Department. No authorizations will be issued for a substantial fill in an estuary for a non-water dependent use unless all of the following apply:

(a) The fill is for a public use;

(b) The fill satisfies a public need that outweighs the harm, if any, to navigation, fisheries and recreation; and

(c) The removal-fill meets all other review standards.

(8) Written Findings. In the following cases, the Department will prepare written findings to document a decision for an authorization under a GP:

(a) Permit denial;

(b) Fill of two acres or more in wetlands;

(c) Fill in estuaries (except cable crossings, pipelines, or bridge construction);

(d) Removal from estuaries of more than 10,000 cubic yards of material (except for maintenance dredging);

(e) Placement of greater than 2,500 cubic yards of riprap in coastal streams or estuaries;

(f) Removal-fill in the Oregon Territorial Sea in accordance with Statewide Planning Goal 19-Ocean Resources; and

(g) Any permit decision that is contrary to the final decision recommendation of a state agency.

(9) Marine Reserves and Marine Protected Areas. The Department will only authorize a removal-fill activity within an area designated by the State Land Board as a marine reserve or a marine protected area if the removal-fill activity is necessary to study, monitor, evaluate, enforce, protect or otherwise further the studying, monitoring, enforcement and protection of the reserve or marine protected area.

General Conditions

(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) Work Area Isolation. The work area must be isolated from the water during construction. All structures and materials used to isolate the work area must be removed immediately following construction and water flow returned to pre-construction conditions. All fish must be salvaged from the isolated area in accordance with Oregon Department of Fish and Wildlife requirements.

(15) 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.

(16) Additional Conditions. The Department may impose additional conditions, if necessary, to eliminate and reduce the reasonably expected adverse impacts of project development to waters of this state. OAR 141-093-0135

Mitigation

(1) General Requirements. Mitigation may be accomplished by either permittee responsible mitigation projects or by purchasing credits from an established mitigation bank. Mitigation must be conducted according to the following general requirements:

(a) Out-of-kind mitigation is not allowed for vernal pool impacts;

(b) All mitigation projects must meet the ratios and site suitability criteria described in this section.

(c) Mitigation for vernal pool impacts must consist of either protect and manage or restore and manage, or both. Neither enhancement of existing wetland nor creation of wetlands where they did not previously occur is recognized as suitable mitigation for this GP;

(d) Combination credits may be used only once (for wetlands or ESA species separately or for an impact that requires both types); and

(e) The amount of mitigation required to offset impacts to waters of the state depends on both the mitigation site base ratios and the impact site multipliers, as described in this section.

(2) Mitigation Site Base Ratios. Mitigation site base ratios are used to determine the number of credits generated by each type of mitigation, as follows:

(a) One and one-half acres of wetland protected and managed generates one wetland or combination credit (1.5:1 ratio), and

(b) One acre of wetland restored and managed generates one wetland or combination credit (1:1 ratio).

(3) Impact Site Multiplier. The impact site multiplier determines the number of credits that must be purchased from a bank or generated at a permittee responsible mitigation site to offset impacts associated with a project.

(a) The impact acreage is multiplied by 2 if the project meets both of the following:

(A) The vernal pool function ranking of the impact wetland is less than or equal to the 30th percentile score in the AD Inventory; and

(B) The total vernal pool wetland impact for the project is less than 0.5 acres.

(b) The impact acreage is multiplied by 2.5 if the project meets any one of the following:

(A) The vernal pool function ranking is less than or equal to the 30th percentile score in the AD Inventory and the total impact for the project is more than 0.5 acre of vernal pool wetland;

(B) The vernal pool function ranking is between the 30th and 70th percentile scores in the AD Inventory;

(C) The vernal pool wetland proposed for impact is within a USFWS designated critical habitat unit as shown on the Department Web site; or

(D) The vernal pool wetland proposed for impact is hydrologically contiguous with any VPC of 10-30 acres.

(c) The impact acreage is multiplied by 3 if the project meets any one of the following:

(A) The vernal pool function ranking is equal to or greater than the 70th percentile score in the AD Inventory; or

(B) The vernal pool wetland proposed for impact is hydrologically contiguous with any VPC >30 acres.

(d) For impacts to other waters, the impact acreage is multiplied by 2.

(4) Mitigation Site Suitability Criteria. All of the following criteria must be met for a proposed mitigation site under this GP:

(a) Size. The total effective size of a mitigation site must be at least 70 contiguous acres of VPC. The Department will consider adjacent, permanently protected parcels dedicated to vernal pool conservation as part of the total effective size if they have uninterrupted continuity of soils, water flows, and topography. The Department may determine that smaller parcels (10-70 acres) of VPC may be adequate in isolation if they exist within areas in which surrounding land uses are compatible with long-term VPC habitat conservation;

(b) Buffers. Mitigation sites must include sufficient area to maintain the hydrologic regime, soils, topography, and vegetation conditions to provide suitable habitat for the typical suite of vernal pools species. The mitigation site must include the surrounding upland mounds and adjacent areas adequate to buffer the VPC habitats against effects from adjacent land uses.

(c) Fairy Shrimp Presence. Mitigation sites must demonstrate at least 10 percent occupancy by vernal pool fairy shrimp, unless only restore and manage mitigation is proposed;

(d) Functionality. Mitigation sites must meet the 70th percentile ranking of the function assessment score, unless only restore and manage mitigation is proposed;

(e) Hardpan. All proposed mitigation sites and must have an intact hardpan layer and no activity anticipated that would perforate the hardpan (e.g. utility easement). If the hardpan is perforated within 100 feet of the mitigation site, or if it is anticipated in the future, the area of the mitigation site adversely affected, as determined by the Department, may generate half of the credits otherwise generated per OAR 141-093-0200(2);

(f) Net gain. Mitigation projects proposed for lands that are already designated for conservation purposes must provide benefits to vernal pool habitats and species above and beyond those resulting from the current conservation status of the lands. For such cases, the number of credits generated will be determined by the Department.
