Purpose and Goals

(1) The leading use on private forestland is the growing and harvesting of trees, consistent with sound management of soil, air, water, fish and wildlife resources. There is a unique concentration of public resource values in and near waters of the state because these areas are critical for the overall maintenance of fish and wildlife and for maintaining water quality. Consequently, the policies of the Forest Practices Act, including encouraging econoically efficient forest practices, are best achieved by focusing protection measures in riparian management areas.

(2) OAR 629-635-0000 through 629-660-0060 shall be known as the "water protection rules."

(3) The purpose of the water protection rules is to protect, maintain and, where appropriate, improve the functions and values of streams, lakes, wetlands, and riparian management areas. These functions and values include water quality, hydrologic functions, the growing and harvesting of trees, and fish and wildlife resources.

(4) The water protection rules include general vegetation retention prescriptions for streams, lakes and wetlands that apply where current vegetation conditions within the riparian manage-ment area have or are likely to develop characteristics of mature forest stands in a "timely manner." Landowners are encouraged to manage stands within riparian management areas in order to grow trees in excess of what must be retained so that the excess may be harvested.

(5) The water protection rules also include alternative vegetation retention prescriptions for streams to allow incentives for operators to actively manage vegetation where existing vegetation conditions are not likely to develop characteristics of mature conifer forest stands in a "timely manner."

(6) OARs 629-640-0400 and 629-645-0020 allow an operator to propose site-specific prescriptions for sites where specific evaluation of vegetation within a riparian management area and/or the condition of the water of the state is used to identify the appro-priate practices for achieving the vegetation and protection goals.

(7) The overall goal of the water protection rules is to provide resource protection during operations adjacent to and within streams, lakes, wetlands and riparian management areas so that, while continuing to grow and harvest trees, the protection goals for fish, wildlife, and water quality are met.

(a) The protection goal for water quality (as prescribed in ORS 527.765) is to ensure through the described forest practices that, to the maximum extent practicable, non-point source discharges of pollutants resulting from forest operations do not impair the achievement and maintenance of the water quality standards.

(b) The protection goal for fish is to establish and retain vegetation consistent with the vegetation retention objectives described in OAR 629-640-0000 (streams), OAR 629-645-0000 (significant wetlands), and OAR 629-650-0000 (lakes) that will maintain water quality and provide aquatic habitat components and functions such as shade, large woody debris, and nutrients.

(c) The protection goal for wildlife is to establish and retain vegetation consistent with the vegetation retention objectives described in OAR 629-640-0000 (streams), OAR 629-645-0000 (significant wetlands), and OAR 629-650-0000 (lakes) that will maintain water quality and habitat compo-nents such as live trees of various species and size classes, shade, snags, downed wood, and food within riparian management areas. For wildlife species not necessarily reliant upon riparian areas, habitat in riparian management areas is also emphasized in order to capitalize on the multiple benefits of vegetation retained along waters for a variety of purposes.

Applicability and Monitoring

(1) Except as described below, the water protection rules shall become effective on September 1, 1994 and shall be applied as follows:

(a) Operations for which a notification has been received after April 22, 1994, must comply with the water protection rules in all portions of the operation that have not been felled prior to September 1, 1994.

(b) Operations for which a notification has been received and a written plan has been approved by the State Forester on or before April 22, 1994, shall continue to comply with the written plan and the rules that were in effect April 21, 1994, through December 31, 1994, unless the operator has requested and the State Forester has approved a change to the water protection rules as allowed in subsection(1)(d).

(c) After December 31, 1994 the water protection rules shall apply fully to all operations.

(d) Operators may request to have the water protection rules apply to an operation at any time following April 22, 1994. The State Forester shall approve such requests so long as the operator will fully apply the water protection rules on the operation.

(2)(a) For the purposes of the Oregon Forest Practices Act (ORS 527.610 to ORS 527.770, and related sections, Chapter 919, Oregon Laws 1991), Type F and Type D streams classified under OAR 629-635-0200 are equivalent to "Class I streams."

(b) For the purposes of ORS 215.730(1)(b)(c), Type N Streams classified under OAR 629-635-0200 are equivalent to "Class II streams."

(3)(a) Monitoring and evaluation of the water protection rules are necessary because of the innovative approach taken in the rules. Monitoring and evaluation are needed to increase the level of confidence of all concerned that the rules will maintain and improve the condition of riparian vegetation and waters of the state over time.

(b) In cooperation with state and federal agencies, landowners and other interested parties, the department shall conduct monitoring on a continuing basis to evaluate the effectiveness of the water protection rules. The monitoring shall determine the effectiveness of the rules to meet the goals of the Forest Practices Act and the purposes stated in the rules, as well as their workability and operability.

(c) It is the Board of Forestry's intent that the department and its cooperators place a high priority on assessing the monitoring needs and securing adequate resources to conduct the necessary monitoring. The department shall work with its cooperators and the Legislature to secure the necessary resources, funding and coordination for effective monitoring.

(d) The department shall report to the Board of Forestry annually about current monitoring efforts and, in a timely manner, present findings and recommendations for changes to practices. The Board of Forestry shall consider the findings and recommendations and take appropriate action.

Watershed Specific Practices for Water Quality Limited Watersheds and Threatened or Endangered Aquatic Species

(1) The objective of this rule is to describe a process for determining whether additional watershed specific protection rules are needed for watersheds that have been designated as water quality limited or for watersheds containing threatened or endangered aquatic species.

(2) The Board of Forestry shall appoint an interdisciplinary task force, including representatives of forest landowners within the watershed and appropriate state agencies, to evaluate a watershed, if the board has determined based on evidence presented to it that forest practices in a watershed are measurably limiting to water quality achievement or species maintenance, and either:

(a) The watershed is designated by the Environmental Quality Commission as water quality limited; or

(b) The watershed contains threatened or endangered aquatic species identified on lists that are adopted by rule by the State Fish and Wildlife Commission, or are federally listed under the Endangered Species Act of 1973 as amended.

(3) The board shall direct the task force to analyze conditions within the watershed and recommend watershed-specific practices to ensure water quality achievement or species maintenance.

(4) The board shall consider the report of the task force and take appropriate action.

(5) Nothing in this rule shall be interpreted to limit the Board's ability to study and address concerns for other species on a watershed basis.

Written Plans for Streams, Lakes, Wetlands and Riparian Management Areas

(1) Operators shall submit to the State Forester a written plan before conducting any operation requiring notification under OAR 629-605-0140(1) within:

(a) 100 feet of fish use or domestic water use streams (classified as Type F or Type D under OAR 629-635-0200), except as described in section (3) of this rule;

(b) 300 feet of significant wetlands;

(c) 100 feet of large lakes.

(2) In addition to the written plan requirements in OAR 629-605-0170, operators shall specifically describe in the written plan for operations within 100 feet of domestic water use portions of Type F or D streams the practices and methods that will be used to prevent sediment from entering waters of the state.

(3) The State Forester may waive, in writing, the requirement for a written plan within 100 feet of a Type F or Type D stream, if the State Forester determines the intended forest practice will not directly affect the physical components of the riparian management area. "Physical components" means materials such as, but not limited to, vegetation, snags, rocks, and soil. "Directly affect" means that physical components will be moved, disturbed, or otherwise altered by the operation activity, even if only temporarily.

(4) Written plans required under section (1)(a) and (1)(b) of this rule are subject to the process required for a written plan pursuant to ORS 527.670(8) through (12), and appeal pursuant to ORS 527.700.

Water Classification

(1) The purpose of this water classification system is to match the physical characteristics and beneficial uses of a water body to a set of appropriate protection measures.

(2) For the purposes of applying appropriate protection measures, waters of the state shall be classified as either streams, wetlands, or lakes.

(3) Streams shall be classified further according to their beneficial uses and size.

(4) Streams shall be classified into one of the following three beneficial use categories:

(a) Streams that have fish use, including fish use streams that have domestic water use, shall be classified as Type F.

(b) Streams that have domestic water use, but not fish use, shall be classified as Type D.

(c) All other streams shall be classified as Type N.

(5) For purposes of classification, a stream is considered to have domestic water use only if a water use permit has been issued by the Oregon Water Resources Department.

(6) A channel is considered to have domestic water use upstream of an intake for the distances indicated below:

(a) For domestic water use that is a community water system (as defined under OAR 333-061-0020), Type D classification shall initially apply to the length of stream that was designated as Class I under the classification system that was in effect on April 22, 1994, which is that shown on district water classification maps at the time of adoption of this rule.

(b) For domestic water use that is not a community water system, Type D classification shall be initially applied for the shortest of the following distances:

(A) The distance upstream of the intake to the farthest upstream point of summer surface flow;

(B) Half the distance from the intake to the drainage boundary; or

(C) 3000 feet upstream of the intake.

(c) Type D classification shall apply to tributaries off the main channel as long as the condi-tions of subsections (6)(a) and (b) of this rule apply.

(7)(a) A representative of a community water system or other domestic use water permit holder may request that the department designate additional lengths of channels upstream of a domestic water intake or reservoir as Type D. The representative or permit holder must present evidence that the additional stream protection is needed. The department will decide whether or not to extend Type D classification to these other channels based on evidence presented by the requesting party showing that protection measures associated with Type N classification would be insufficient to prevent adverse detrimental temperature increases, turbidity increases, or other adverse water quality changes at the domestic water use intake or reservoir.

(b) The process and criteria described in subsection (7)(a), and the criteria under section (6) of this rule will be used to evaluate the extent of Type D classification for new community water systems.

(c) The department will decide whether or not to extend the length of Type D classification within 30 days of the presentation of evidence.

(8) The domestic water use classification may be waived by the department at the request of a landowner who is the sole domestic water use permit holder for an intake and who owns all the land along upstream channels that would be affected by the classification related to that intake. This waiver shall not affect the classification related to downstream domestic water use intakes.

(9) A stream or lake will be considered to have fish use if inhabited at any time of the year by anadromous or game fish species or fish that are listed as threatened or endangered species under the federal or state endangered species acts.

(10) The fish use classification does not apply to waters where fish were introduced through a fish stocking permit that includes documentation that the stream had no fish prior to stocking.

(11) The department, with assistance from the Oregon Department of Fish and Wildlife, will conduct a comprehensive field survey to identify fish use on non-federal forestland in Oregon. However, this survey will take a number of years to complete. In the interim, the following procedures apply to determining which unsurveyed waters are designated Type F:

(a) The department will assume that waters have fish use if they were Class I under the previous classification system. Waters that were Class I solely because of domestic water use are excluded.

(b) If waters within the boundaries of a proposed operation were not Class I (under the previous classification system) and fish use is unknown, then:

(A) The department will conduct a field survey for fish after a notification of operation is received; or

(B) The department will approximate the upstream extent of fish use in a watershed by considering the connection of the water with downstream waters where fish use is known. Fish use will be assumed to occur upstream of the known fish use until the first natural barrier to fish use is encountered.

(c) Where fish use is unknown, an operator may request that the department conduct a field survey for fish use for reaches of a stream that will be included within an operation that is scheduled to start at least 12 months following the request. The operator shall limit such requests to operations that are part of a landowner's planned harvest schedule and will be conducted during the following year. The department, with assistance from the Oregon Department of Fish and Wildlife when needed, shall attempt to complete such surveys within 12 months following the request. If the survey cannot be conducted in the time indicated, the stream will be considered to have no fish use. However, if the operation has not commenced within six months of the time the operation was scheduled to begin, the stream will again be considered to have unknown fish use.

(d) The department may use other reliable fish survey information when determining whether or not a stream has fish use. This information could include surveys done by landowners, federal or state agencies, universities, or other persons or entities. The department will determine whether such information is reliable.

(12) For each of the three beneficial use categories (Type F, Type D, and Type N), streams shall be categorized further according to three size categories: large, medium, and small. The size categories are based on average annual flow.

(a) Small streams have an average annual flow of two cubic feet per second or less.

(b) Medium streams have an average annual flow greater than 2 and less than 10 cubic feet per second.

(c) Large streams have an average annual flow of 10 cubic feet per second or greater.

(13) The assignment of size categories to streams on forestland will be done by the department as follows:

(a) The department will index average annual flow to the upstream drainage area and average annual precipitation. The methodology is described in Technical Note FP1 dated April 21, 1994.

(b) Actual measurements of average annual flow may substitute for the calculated flows described in the technical note.

(c) Any stream with a drainage area less than 200 acres shall be assigned to the small stream category regardless of the flow index calculated in subsection (13)(a).

(14) Wetlands shall be classified further as indicated below:

(a) The following types of wetlands are classified as "significant wetlands":

(A) Wetlands that are larger than 8 acres;

(B) Estuaries;

(C) Bogs; and

(D) Important springs in eastern Oregon.

(b) Stream-associated wetlands that are less than 8 acres are classified according to the stream with which they are connected.

(c) All other wetlands, including seeps and springs are classified according to their size as either "other wetlands greater than one-quarter acre" or "other wetlands less than one-quarter acre."

(15) Lakes shall be classified further as indicated below:

(a) Lakes greater than 8 acres are classified as "large lakes."

(b) All other lakes are classified as "other lakes."

Designation of Waters; Notice to Landowners; Reconsideration

(1) The State Forester shall maintain a map showing the classification of waters of the state in each Department of Forestry unit office where notice of operations required by ORS 527.670(6) may be submitted. The map shall show streams, lakes and significant wetlands of known classification within the geographic area of responsibility for that unit office. For streams, the maps shall indicate the size class and, when known, extent of fish use and domestic water use classification.

(2) Once a water of the state has been classified according to OAR 629-635-0200, the State Forester shall not change the classification without written notice to the landowners immediately adjoining the portion(s) of water to be reclassified. Notice to landowners shall include the reason for the change of classification and applicable rules.

(3) Any landowner whose land immediately adjoins the water to be reclassified, any landowner who has received a water right or was granted an easement affecting the water classification, or any state resource agency may request reconsideration of classifications of waters of the state by the department. Such a request shall be in writing and shall identify on a map the portion of the stream or water of the state which should be reconsidered. The request shall present evidence that the current classification is not consistent with OAR 629-635-0200 "Water Classification."

(4) The department shall have up to 14 days to provide a final decision on a request for reconsideration of water classification. Until such a decision is provided, operators shall conduct any operation based upon the most protective potential water classification.

Riparian Management Areas and Water Quality Protection Measures

(1) Riparian management area widths are designated to provide adequate areas along streams, lakes, and significant wetlands to retain the physical components and maintain the functions necessary to accomplish the purposes and to meet the protection objectives and goals for water quality, fish, and wildlife set forth in OAR 629-635-0100.

(2) Specified protection measures, such as for site preparation, yarding and stream channel changes, are required for operations near waters of the state and within riparian management areas to maintain water quality.

(3)(a) Operators shall apply the specified water quality protection measures and protect riparian management areas along each side of streams and around other waters of the state as described in OAR 629-635-0310 through 629-660-0060.

(b) Operators may vary the width of the riparian management area above or below the average specified width depending upon topography, operational requirements, vegetation, fish and wildlife resources and water quality protection as long as vegetation retention and protection standards are met. However, the average width of the entire riparian management area within an operation must equal or exceed the required width.

protection measures, and

see OAR 629-640-0200.

(b) Except as indicated in section (2), operators shall measure the riparian management area width as a slope distance from the high water level of main channels.

(c) Notwithstanding the distances designated in subsection(1)(a), where wetlands or side channels extend beyond the designated riparian management area widths, operators shall expand the riparian management area as necessary to entirely include any stream-associated wetland or side channel plus at least 25 additional feet. This provision does not apply to small Type N streams.

(2) In situations where the slope immediately adjacent to the stream channel is steep exposed soil, a rock bluff or talus slope, operators shall measure the riparian management area as a horizontal distance until the top of the exposed bank, bluff or talus slope is reached. From that point, the remaining portion of the riparian management area shall be measured as a slope distance.
