Appendix A - Guidance for Use of the Resource 

Management Plan 

This section provides guidance on how the resource management plan will be implemented, evaluated, and 

changed by the district. 

Requirement for Further Environmental Analysis 

The BLM makes many types of decisions. It is important to distinguish between land use plan decisions and 

implementation decisions because: (1) the administrative remedies and the timing of those remedies differ; 

(2) the NEPA analysis necessary to support implementation decisions is generally more site specific than 

the analysis necessary to support land use plan decisions; (3) the authority to make these types of decisions 

varies; and (4) the scope and effect of each type of decisions would be considered during the compliance and 

consultation proceedings required under various environmental laws. 

• Land use plan decisions consist of desired outcomes (goals, standards, objectives), allowable uses 

(land use allocations, levels of use, restrictions on uses), and management direction necessary to 

achieve the outcomes. 

• Implementation decisions are actions to implement land use plans. These types of decisions are 

based on site-specific planning and NEPA analyses. Examples of implementation decisions include: 

offering a specific tract of timber for sale, applying a vegetation treatment, offering a specific oil 

or gas lease for sale, application for a permit to drill (APDs), selling an individual grazing lease or 

processing a specific permit application, designating specific roads and trails as open or closed to 

motorized travel, or completing a specific land exchange. 

This resource management plan only provides direction for the management of natural resources on BLMadministered lands. This plan does not authorize the implementation of any specific project-level actions. 

Decisions on which projects, including specific on-the-ground locations and timing of a project, will be 

made subsequent to the adoption of this Resource Management Plan. Decisions on specific projects will be 

made by BLM employees delegated to make those decisions after compliance with National Environmental 

Policy Act and required consultation has been completed. 

Plan Evaluation 

Evaluation is the process of reviewing the land use plan to determine whether plan decisions are being 

implemented as expected, and whether the associated NEPA analyses are still valid. Based on this 

evaluation, a determination is made as to whether a plan amendment or revision is warranted. Land use 

plans are evaluated to determine if: 

• Decisions remain relevant to current issues. 

• Decisions are effective in achieving (or making progress toward achieving) desired objectives. 

• Any decisions need to be revised. 

• Any decisions need to be dropped from further consideration. 

• Any areas require new decisions. 

The plan will be formally evaluated every 5 years, or as necessitated by changed circumstances or significant 

new information. These evaluations will focus on issues resulting from monitoring or new information. 

A – 3
 
Roseburg District ROD and RMP 

The evaluation will also review major assumptions regarding the level of management activities used in the 

analysis of effects for the Final Environmental Impact Statement for the Revisions of the Western Oregon 

BLM Districts. Much of the data needed for evaluating these assumptions related to anticipated levels of 

activity will be collected through program reporting associated with the RMP monitoring plan. 

Unscheduled plan evaluations could be conducted to address certain unanticipated events or new 

information that calls into question the underlying analysis and decisions of the plan. These unscheduled 

plan evaluations may examine a single or relatively narrow aspect of the resource management plan. 

Plan Maintenance 

Land use plan decisions can be maintained to reflect minor changes in data. Maintenance is limited to 

further refining, documenting, or clarifying a previously approved decision. Plan maintenance will not 

expand the scope of resource uses or restrictions or change the terms, conditions, and decisions of the 

approved plan. Plan maintenance may be used to adjust the annual sustained yield capacity based on 

updated operations inventory data. 

Plan Amendments 

New information, updated analyses, or new resource use or protection proposals may require amending or 

revising land use plans and updating implementation decisions. Re-examining existing plan decisions, or 

the analysis in the FEIS for the Revision of the Resource Management Plans for the Western Oregon BLM 

Districts, will be appropriate if new information or circumstance has come to light that could significantly 

alter the underlying conclusions of the FEIS regarding environmental consequences or the ability to achieve 

management objectives. 

Plan amendments change one or more of the terms, conditions, or decisions of an approved land use plan. 

Plan amendments are most often prompted by the need to: 

• Consider a proposal or action that does not conform to the plan. 

• Implement new or revised policy that changes land use plan decisions, such as an approved 

conservation agreement between the BLM and the USFWS. 

• Respond to new, intensified, or changed uses on public land. 

• Consider significant new information from resource assessments, plan evaluations, monitoring, or 

scientific studies. 

Plan amendments will follow BLM planning regulations and can be accompanied by either an 

environmental assessment or environmental impact statement. 

Plan Revisions 

Resource management plan revisions involve preparation of a new plan to replace an existing one. Resource 

management plan revisions will be necessary if monitoring and evaluation findings, new data, new or 

revised policy, or changes in circumstances indicate that decisions for an entire plan or a major portion of 

the plan would no longer serve as a useful guide for resource management. Plan revisions are accomplished 

through the BLM planning regulations and are accompanied by an environmental impact statement. 

Valid Existing Rights 

Considering the intermingled nature of the O&C lands in the planning area, an immense number of rightsA – 4
 
Appendix A - Guidance for Use of the RMP 

of-way, leases, corridors, and other established legal rights have been granted over the years in establishing 

an effective cooperative management framework among a variety of owners. Perhaps the most extensive and 

unique rights are the reciprocal rights-of-way agreements established with dozens of adjacent landowners 

to provide for the logical, effective, and efficient development of access on the intermingled lands. Mining 

claims, water rights, and county roads are other examples. When implementing resource management plans, 

it is recognized there are some instances when actions that may occur on public lands are subject to these 

valid existing rights. In those cases, authorization for implementing an action may be subject to approval by 

the holders of valid existing rights and may not be discretionary to the BLM. 

Management of Newly Acquired Lands 

Lands may come under BLM administration through exchange, donation, purchase, revocation of 

withdrawals to other federal agencies, or relinquishment of Recreation and Public Purpose leases. 

Discretionary acquisitions (such as exchanges) will be guided by the Lands Acquisition Criteria, based on 

resource values of high public interest. (Note: See Appendix F – Lands for the Lands Acquisition Criteria.) 

Newly acquired or administered lands or interests in lands will be managed for their highest potential or 

for the purposes for which they are acquired. For example, lands acquired within the boundary of a “special 

management area” with Congressional or resource management plan allocations/direction will be managed 

in conformance with management objectives and guidelines for that area. Lands acquired outside of 

designated special management areas will be managed in the same manner as comparable or adjacent BLMadministered lands. In western Oregon, this implies forest management activities, including timber harvest, 

management of the mineral estate, standard operating procedures, and pre-committed mitigation measures. 

If lands with unique or fragile resource values are acquired outside of special management areas, it may be 

appropriate to protect those values until the next plan revision. Lands acquired adjacent to or within existing 

or proposed withdrawals identified in this plan that possess similar critical resource values will be proposed 

for withdrawal. Newly acquired lands, regardless of status, will be subject to non-discretionary access rights 

provided for under the terms and conditions of most reciprocal right-of-way agreements and permits. 

In accordance with Section 205 (e) of FLPMA (P.L. 99-632), lands acquired by the BLM in exchange for 

O&C or Coos Bay Wagon Road (CBWR) lands will have the same status and be administered in accordance 

with the same provisions of law applicable to those lands disposed of; and those newly acquired lands will 

be designated as O&C or CBWR lands, as appropriate, and managed under the sustained yield principles 

as prescribed in the Act of August 28, 1937 and other laws applicable to the O&C or CBWR lands. 

Additionally, lands acquired using proceeds generated from the disposal of O&C or CBWR lands under the 

authority of the Federal Land Transaction Facilitation Act (Public Law 106-248) will also take on the same 

status as the lands from which the funds were generated (O&C or CBWR) and will likewise be managed in 

accordance with the Act of August 28, 1937 and other applicable laws. 

Lands acquired by the BLM that take on the status of either O&C or CBWR will require classification in 

accordance with the Act of June 9, 1916 as to power-site, timberlands, or agricultural lands. Lands classified 

as timberland or agriculture will be open to exploration, location, entry and disposition under the general 

mining laws in accordance with the Act of April 8, 1948. Lands acquired by the BLM under Section 205 or 

206 of FLPMA take on the status of “acquired lands,” and therefore will not be available for location, lease, or 

sale until the land is formally opened to such entry. 

Land acquisitions resulting in net adjustments in the commercial forestland base may be made without 

adjusting the allowable sale quantity or amending the resource management plan, unless the cumulative 

effects of all changes indicate that the decadal allowable sale quantity for any sustained yield unit should be 

modified by more than 10 percent of the allowable sale quantity.

Monitoring Plan for the Roseburg District Resource 

Management Plan 

The monitoring plan for the Roseburg District Resource Management Plan is carefully designed to 

avoid prohibitive costs and effectively answer monitoring questions and reporting levels of activities. It 

is not necessary or desirable to monitor every activity and management action or objective of a resource 

management plan. 

Monitoring for the resource management plan will examine if activities are in accordance with management 

direction (implementation monitoring), if management objectives are being met or are likely to be met 

(effectiveness monitoring), and if management objectives and management actions are based on correct 

assumptions (validation monitoring). Most monitoring will be designed to provide information as to 

whether activities are in accordance with management direction. 

Some management objectives and management directions in the Roseburg District Resource Management 

Plan are not measurable or quantifiable, or do not have a standard or threshold of acceptability, and 

therefore will not lend themselves to being addressed through monitoring questions which are almost 

always dependent on a quantifiable basis of measurement. The level of activity for certain management 

directions that do not have standards or thresholds of acceptability will be monitored in the form of a 

program reporting item. 

In some cases, where monitoring indicates very high compliance with the plan, the frequency or interval of 

monitoring will subsequently be adjusted for cost and time efficiency. 

Sampling or evaluation of a subset of actions will be employed to avoid unnecessary detail and unacceptable 

costs. Projects to be monitored will be selected on the basis of those that will yield a greater amount of 

information or be more beneficial. For example, a random sample may result in monitoring of a relatively 

small straightforward project that will yield limited information, whereas a more sophisticated or complex 

project might be available for monitoring that will yield more information or be more effective. Sampling 

will be done at the level of the entire administrative unit to which the resource management applies (e.g., 

Roseburg District). 

The monitoring questions will be evaluated at each monitoring interval to ascertain if the questions, 

reporting, methods, sample size, or intervals need to be changed. Such changes to the monitoring plan will 

be accomplished through plan maintenance. 

Monitoring results will be reported annually in a Monitoring Report and published as part of the 

Annual Program Summary. The Monitoring Report will report, track, and assess the progress of plan 

implementation; state the findings and conclusions made through monitoring; and serve as a report 

to managers and the public. Monitoring reports will also include any discussions and analysis of noncompliance and recommendations for corrective action. 

The use of this monitoring plan will provide a basis for consistent and coordinated monitoring, and allow 

district information to be compiled and considered at the scale of the entire western Oregon planning area.

Roseburg District ROD and RMP 

Other Monitoring 

The monitoring plan for the Roseburg District Resource Management Plan is designed to focus specifically on 

monitoring the resource management plan itself and is not intended as an overarching plan that addresses all 

ongoing monitoring and research efforts. This monitoring plan does not attempt to address science questions 

or issues of a regional or interagency scale. There are many ongoing regional, interagency, and research 

(science-based) efforts in which the BLM participates that address these broader issues. Although these other 

efforts in which the BLM participates often have important implications for BLM-administered lands and 

resources in western Oregon, they will be addressed externally from this monitoring plan. 

Plan Evaluations 

Plan evaluations will occur at five-year intervals. In addition to the monitoring results, many of the 

underlying assumptions regarding levels of activities and anticipated environmental consequences will be 

examined at the time of the five-year plan evaluation to determine if the plan objectives are being met or 

are likely to be met. The evaluation will also assess whether changed circumstances or new information 

have created a situation in which the expected impacts or environmental consequences of the plan 

are significantly different than those anticipated in the Final Environmental Impact Statement for the 

Revision of the Resource Management Plans of the Western Oregon Bureau of Land Management Districts 

(published in October 2008). The plan evaluation will make a finding of whether or not a plan amendment 

or plan revision is warranted. 

B – 4
 
Appendix B - Monitoring 

Adaptive Management 

Adaptive management is not a stand-alone program or process. Adaptive management for the Roseburg 

District Resource Management Plan will be integrated into NEPA and land use planning processes. 

See Figure B-1 (Land use planning, monitoring, and adaptive management). Identified outcomes for the 

resource management plan are described in the plan’s management objectives. Resource management plan 

monitoring will determine if the objectives are being met or are likely to be met.
 

In addition to monitoring results, new information or changed circumstances will be evaluated as to 

whether changes in resource management plan decisions or changes in supporting NEPA analyses are 

warranted. Adaptive management tools and procedures that will be used to make changes in the plan 

in response to monitoring information, new information, or changed circumstances include: plan 

maintenance, plan evaluations, plan amendments and plan revisions. In addition to these planning 

instruments, NEPA documentation may be necessary. The NEPA procedures relevant to adaptive 

management will include the use of categorical exclusions, determination of NEPA adequacy reviews, 

environmental assessments, and environmental impact statements. Unscheduled plan evaluations can be 

conducted to address certain unanticipated events or new information that could call into question the 

underlying analysis and decisions of the plan.
 

In some instances, management direction provides for a range of activities or resource uses. In these cases, 

levels of activities or resource uses will vary within the range prescribed by the management action without 

the use of planning steps or NEPA analyses. The level of activities will be adapted within the range given by 

management action, depending on variation in resource needs or organizational capability.
 

In addition to the constraints or latitude provided by management direction, the ability to adapt or 

change management without the use of planning steps or NEPA analyses will be restricted by how much a 

departure would be from analytical assumptions in the environmental impact statement. This is because the 

conclusions regarding environmental consequences are derived from analytical assumptions. Analytical 

assumptions include such things as levels or methods of activities, number of acres treated, and miles of 

roads maintained. 

If, as a result of the need for adaptive management changes, implementation of the resource management 

plan would so alter the methods or levels of activities to the degree that the environmental consequences 

might be substantively different than those anticipated in the environmental impact statement, then formal 

planning steps and NEPA procedures will be required. The determination as to when formal planning steps 

and NEPA procedures would be required will be made through the plan evaluation process. Plan evaluations 

could include an overall resource management plan evaluation such as occurs at five-year intervals or a 

narrowly focused evaluation of a specific aspect of the resource management plan. Plan evaluations will 

be scheduled at five-year intervals. Unscheduled plan evaluations can be conducted to address certain 

unanticipated events or new information, such as a very large wildfire.
 

Adaptive management will also be applied by acting on information found through the monitoring 

questions. Adaptive management associated with monitoring will include corrective actions precipitated by 

findings of non-compliance. Corrective action precipitated by monitoring can range from simple changes in 

administrative procedures, refinements of the plan through plan maintenance, or more substantive changes 

through plan amendments.

Appendix B - Monitoring 

Monitoring Questions 

Monitoring of certain questions will not take place in the early years of implementation, because projects 

would not yet have been completed and, therefore, would not be ready for monitoring. Although incomplete 

projects may be informally examined by managers to assess progress towards implementing management 

actions and achieving objectives, the evaluation of incomplete projects will not be part of formal plan 

monitoring. Not all programs or resources have monitoring questions.

Appendix C - Best Management Practices 

Best Management Practices 

Introduction 

A Best Management Practice or BMP is a practice, or combination of practices that have been determined to 

be the most effective and practicable in preventing or reducing the amount of pollution generated by diffuse 

sources to a level compatible with water quality goals (40 CFR 130.2 [m]). 

Best Management Practices are a type of water pollution control. This section defines the best management 

practices (i.e., methods and measures) that were developed for the lands within the western Oregon 

planning area to comply with the requirements of the Clean Water Act. 

Purpose 

Best management practices (BMPs) are required by the federal Clean Water Act, as amended to reduce 

nonpoint source pollution to the maximum extent practicable. Nonpoint source pollution is pollutants 

detected in a concentrated water source such as a stream, or lake that come from a wide range of forest 

and range activities. The BMPs are considered the primary controls for achieving Oregon’s water quality 

standards. Oregon’s narrative criteria, which include numeric standards, are designed to protect designated 

beneficial uses (such as salmonid spawning and rearing, resident fi sh and aquatic life, domestic water 

supplies, and water-contact recreation). 

The BMPs are methods, measures, or practices selected on the basis of site-specific conditions to ensure 

that water quality will be maintained at its highest practicable level. The BMPs include, but are not limited 

to, avoidance, structural and nonstructural treatments, operations, and maintenance procedures. Although 

normally preventative, BMPs can be applied before, during, and after pollution-producing activities to 

reduce or eliminate the introduction of pollutants into receiving waters (40 CFR 130.2, EPA Water Quality 

Standards Regulation). 

Organization and Use 

The BMPs in this appendix are organized by the following management activities: 

• roads and landings 

• timber harvest activities 

• silvicultural activities 

• fire and fuels management 

• surface source water for drinking water 

• recreation 

• grazing 

• minerals exploration and development 

• spill prevention and abatement 

• restoration 

The tables that follow this introduction identify the input variables, causal mechanisms, and water quality 

standards (referenced by the Oregon Administrative Rules number) that are associated with each BMP. 

C – 3
 
Roseburg District ROD and RMP 

Those BMPs that are necessary for typical situations have been included. When applied, BMPs are expected 

to prevent water quality degradation and to meet water quality standards. 

Causal mechanisms help explain the outcomes or the process through which an outcome occurs. 

Resource aspects of land management activities normally have many facets that require site-specific BMP 

design. Therefore, there may be some repetition of the BMPs between sections of the following tables. An 

activity may use an individual BMP, whereas another activity may involve BMPs in combination from 

several sections for water quality protection. 

Management of locatable minerals is governed by regulations found in 43 CFR 3809. The BMPs for locatable 

minerals include language from 43 CFR 3809 that requires operators to prevent unnecessary and undue 

degradation from mining operations. 

Some BMPs that relate to instream activities may coincidently be similar to applicable practices specified in 

Army Corps of Engineers, Department of State Lands, and ODFW joint removal/fill permits, DEQ water 

quality permits and 401 certifications, or project design criteria contained in biological assessments. The 

BMPs in the following tables are not specific permit requirements, but rather demonstrate the process by 

which nonpoint source pollution from instream activities would be controlled. 

The BMPs are practices, techniques, or management strategies that have been evaluated through common 

practice or studies, and shown to be an effective and practical means of preventing or reducing nonpoint 

source pollution. The BMPs are not intended to serve as detailed engineering specifications or design 

criteria. Such specifications are available for field use from various sources. 

Application of Best Management Practices 

Selection of BMPs are made by decision-makers using input from soil, water, fisheries, geology and other 

professionals during project-level analyses. It is not intended that all of the BMPs listed will be selected for 

any specific management action. Each activity is unique, based on site-specific conditions, and the selection 

of an individual BMP or a combination of BMPs and measures becomes the BMP design. 

The BMPs must be applied in a manner that is consistent with all Resource Management Plan objectives. The 

overall goal is not to adhere strictly to a particular set of BMPs, but to meet water quality objectives when 

implementing management actions. Describing non-point pollution causal mechanisms allows resource 

professionals (specialists) to exercise discretion as to what will work best in a particular situation. An example 

is the need to respond to a wide range of geology, landform, soils, watershed characteristics and climate. 

Although this appendix does not provide an exhaustive list of BMPs, the included BMPs are believed to 

cover most project activity situations in the Plan area. Additional nonpoint source control measures may be 

identified during the interdisciplinary process when evaluating site-specific management actions. 

Where found to be ineffective, BMPs may require modification to meet water quality objectives. Specialists 

may consider baseline environmental conditions, type of activity, proximity to water, disturbance level, 

direct, indirect, and cumulative effects and timing. They may also evaluate new technology and relevant 

implementation or effectiveness monitoring data, published studies or other sources of information, in 

refining existing BMPs or recommending new BMPs. This process involves continued learning and applying 

monitoring feedback. 

Review and update of this appendix, including BMP corrections or additions that are derivatives of existing 

BMPs, would be completed through plan maintenance.

Summary of Oregon Water Quality Standards 

This section summarizes the Oregon standards and regulations for water quality that are associated with 

the best management practices. 

Statewide Narrative Criteria 

The following are the Oregon administrative rules (OARs) for the statewide narrative criteria for water 

quality by name, number, and descriptive excerpt. 

Antidegradation (OAR 340-04l-0004) 

“The purpose of the Antidegradation Policy is to guide decisions that affect water quality such that 

unnecessary further degradation from new or increased point and nonpoint sources of pollution is 

prevented, and to protect, maintain, and enhance existing surface water quality to ensure the full protection 

of all existing beneficial uses.” 

Note: The antidegradation policy applies to all 303(d) listed waterbodies when a project could further 

degrade the water quality. 

Statewide Narrative Criteria Biological Criteria (OAR 340-041-0007) 

“(11) The development of fungi or other growths having a deleterious effect on stream bottoms, fi sh or other 

aquatic life, or that are injurious to health, recreation, or industry may not be allowed.” 

Statewide Narrative Criteria Oil and Floating Solids (OAR 340-041-0007) 

“(14) Objectionable discoloration, scum, oily sheens, or floating solids, or coating of aquatic life with oil 

films may not be allowed.” 

Statewide Narrative Criteria Road Building Waste Materials (OAR 340-041-0007) 

“(9) Road building and maintenance activities must be conducted in a manner so as to keep waste materials 

out of public waters and minimize erosion of cut banks, ,fill s and road surfaces. ”

Statewide Narrative Criteria Sediment, Adverse Deposits(OAR 340- 041-0007) 

“(13) The formation of appreciable bottom or sludge deposits or the formation of any organic or inorganic 

deposits deleterious to fi sh or other aquatic life or injurious to public health, recreation, or industry may not 

be allowed.” 

Statewide Narrative Criteria Summary (OAR 340-041-0007) 

“(1) Notwithstanding the water quality standards contained in this Division, the highest and best practicable 

treatment and/or control of wastes, activities, and flows must in every case be provided so as to maintain 

dissolved oxygen and overall water quality at the highest possible levels and water temperatures, coliform 

bacteria concentrations, dissolved chemical substances, toxic materials, radioactivity, turbidities, color, odor, 

and other deleterious factors at the lowest possible levels.” 

C – 51
 
Roseburg District ROD and RMP 

Statewide Narrative Criteria Toxics (OAR 340-041-0007) 

“(12) The creation of tastes or odors or toxic or other conditions that are deleterious to fi sh or other aquatic 

life or affect the potability of drinking water or the palatability of fi sh or shellfish may not be allowed.” 

tatewide Numeric Criteria 

The following are the Oregon administrative rules (OARs) for the statewide numeric criteria for water 

S

quality by name, number, and descriptive excerpt. 

Bacteria (OAR 340-041-0009) 

“(1) Numeric Criteria: Organisms of the coliform group commonly associated with fecal sources (MPN) 

or equivalent membrane filtration using a representative number of samples) may not exceed the criteria 

described in paragraphs (a) and (b) of this paragraph: (a) Freshwaters and Estuarine Waters Other than 

Shellfish Growing Waters: 

(A) A 30-day log mean of 126 E. coli organisms per 100 milliliters, based on a minimum of five (5) samples; 

(B) No single sample may exceed 406 E. coli organisms per 100 milliliters.” 

Biocriteria (OAR 340-041-0011) 

“Waters of the State must be of sufficient quality to support aquatic species without detrimental changes in 

the resident biological communities.” 

Dissolved Oxygen (OAR 340-041-0016) 

“Dissolved oxygen (DO): No wastes may be discharged and no activities must be conducted that either 

alone or in combination with other wastes or activities will cause violation of the following standards: The 

changes adopted by the Commission on January 11, 1996, become effective July 1, 1996. Until that time, the 

requirements of this rule that were in effect on January 10, 1996, apply: 

(1) For waterbodies identified as active spawning areas in the places and times indicated on the 

following tables and figures set out in OAR 340-041-0101 to 340-041-0340: Tables 101B, 

121B, 180B, 201B and 260B, and Figures 130B, 151B, 160B, 170B, 220B, 230B, 271B, 286B, 

300B,310B, 320B, and 340B, (as well as any active spawning area used by resident trout 

species), the Rules of this Division as last modified by the EQC 05/20/2004 following criteria 

apply during the applicable spawning through fry emergence periods set forth in the tables 

and figures: 

(a) The dissolved oxygen may not be less than 11.0 mg/l. However, if the minimum intergravel 

dissolved oxygen, measured as a spatial median, is 8.0 mg/l or greater, then the DO 

criterion is 9.0 mg/l; 

(b) Where conditions of barometric pressure, altitude, and temperature preclude attainment 

of the 11.0 mg/l or 9.0 mg/l criteria, dissolved oxygen levels must not be less than 95 

percent of saturation; 

(c) The spatial median intergravel dissolved oxygen concentration must not fall below 8.0 

mg/l. 

(2) For waterbodies identified by the Department as providing cold-water aquatic life, the 

dissolved oxygen may not be less than 8.0 mg/l as an absolute minimum. Where conditions of 

barometric pressure, altitude, and temperature preclude attainment of the 8.0 mg/l, dissolved 

oxygen may not be less than 90 percent of saturation. At the discretion of the Department, 

when the Department determines that adequate information exists, the dissolved oxygen may 

not fall below 8.0 mg/l as a 30-day mean minimum, 6.5 mg/l as a seven-day minimum mean, 

and may not fall below 6.0 mg/l as an absolute minimum (Table 21); 

C – 52 
Appendix C - Best Management Practices 

(3) For waterbodies identified by the Department as providing cool- water aquatic life, the 

dissolved oxygen may not be less than 6.5 mg/l as an absolute minimum. At the discretion 

of the Department, when the Department determines that adequate information exists, the 

dissolved oxygen may not fall below 6.5 mg/l as a 30-day mean minimum, 5.0 mg/l as a sevenday minimum mean, and may not fall below 4.0 mg/l as an absolute minimum (Table 21); 

(4) For waterbodies identified by the Department as providing warm-water aquatic life, the 

dissolved oxygen may not be less than 5.5 mg/l as an absolute minimum. At the discretion 

of the Department, when the Department determines that adequate information exists, the 

dissolved oxygen may not fall below 5.5 mg/l as a 30-day mean minimum, and may not fall 

below 4.0 mg/l as an absolute minimum (Table 21); 

(5) For estuarine water, the dissolved oxygen concentrations may not be less than 6.5 mg/l (for 

coastal waterbodies).” 

Temperature (OAR 340-041-0028) 

“A. The seven-day-average maximum temperature of a stream identified as having salmon and steelhead 

spawning use may not exceed 55.4 degrees Fahrenheit. 

B. The seven-day-average maximum temperature of a stream identified as having core cold water habitat 

use may not exceed 60.8 degrees Fahrenheit. 

C. The seven-day-average maximum temperature of a stream identified as having salmon and trout 

rearing and migration use may not exceed 64.4 degrees Fahrenheit. 

D. The seven-day-average maximum temperature of a stream identified as having a migration corridor 

use may not exceed 68.0 degrees Fahrenheit.” 

Turbidity (OAR 340-041-0036) 

“No more than a ten percent cumulative increase in natural stream turbidities may be allowed, as measured 

relative to a control point immediately upstream of the turbidity causing activity.”
