EMERGENCY RULES
Date of Adoption: January 20, 2000.
Purpose: To modify forest practices rules to provide greater protection for aquatic and riparian dependent resources in response to federal listings under the Endangered Species Act.
The Forest Practices Board has adopted the following goals for new rules:
1. To provide compliance with the Endangered Species Act for aquatic and riparian-dependent species on state and private forest lands;
2. To restore and maintain riparian habitat on state and private forest lands to support a harvestable supply of fish;
3. To meet the requirements of the Clean Water Act for water quality on state and private forest lands; and
4. To keep the timber industry economically viable in the state of Washington.
Adoption of these emergency rules is a significant step toward achieving these goals. The Forest Practices Board is also developing permanent rules and preparing an environmental impact statement on three alternatives.

Statutory Authority for Adoption: RCW 76.09.040, [76.09.]050, and [76.09.]055, and chapter 34.05 RCW.
Other Authority: Chapter 43.21C RCW.
Under RCW 34.05.350 the agency for good cause finds that immediate adoption, amendment, or repeal of a rule is necessary for the preservation of the public health, safety, or general welfare, and that observing the time requirements of notice and opportunity to comment upon adoption of a permanent rule would be contrary to the public interest; and that state or federal law or federal rule or a federal deadline for state receipt of federal funds requires immediate adoption of a rule.
Reasons for this Finding: Legislative declaration that declines of fish stocks require immediate action (RCW 76.09.055(1)).
These emergency rules were adopted under RCW 76.09.055(2). They were published as WSR 99-20-144 and a public hearing was held on November 9, 1999. Another section, WAC 222-30-070 was published as WSR 99-24-087 and a public hearing was held on January 20, 2000. This filing supercedes emergency rules filed under WSR 99-24-089 and WSR 99-24-090. These emergency rules may remain in effect until permanent rules are adopted, or until June 30, 2001, whichever is sooner.

WAC 222-08-035
Continuing review of forest practices
((regulations)) rules.
*(1) Annual evaluations. The
department, after consulting with affected state agencies, Indian
tribes, forest landowners, fish and wildlife, natural resources,
and environmental interest groups, shall beginning July 1, 1988,
report annually to the forest practices board an assessment of
how ((regulations)) the rules and voluntary processes are
working.
*(2) Adaptive management. The cooperative monitoring,
evaluation and research committee (CMER) will provide results of
research and monitoring projects for covered resources (see WAC 222-16-010) to the TFW policy group or similar collaborative
forum in the form of technical recommendations. In the event
that CMER cannot agree on a recommendation within six months of
submittal of a scientific report, the report will be forwarded to
the TFW policy group for review and recommendation to the forest
practices board. In the event that the TFW policy group cannot
agree on a recommendation to the forest practices board within
six months, mediation or arbitration may be used to reach
agreement. The decision by the TFW policy group to use either
arbitration or mediation must be made within one month and the
results must be completed within three months, including the one
month used to decide on either arbitration or mediation. When
the forest practices board receives results of mediation or
arbitration, all information generated should be forwarded to the
forest practices board. In addition, the department is directed
to report to the board on opportunities to modify these
((regulations)) rules when baseline data, monitoring, evaluation
or the use of interdisciplinary teams show that such adaptive
management will better meet the purposes and policies of the
Forest Practices Act.
(3) Resource management plans. The department is directed to develop a method for cooperative voluntary resource management planning among forest landowners, governmental agencies, affected Indian tribes, and environmental groups which would result in the development of plans which might be used as an alternative to the forest practice regulations in achieving the purposes and policies set forth in the act. This should be done through pilot projects, at least one of which should be located on the east side of the Cascade summit and one on the west side of the Cascade summit.

filed 8/29/84, effective 10/1/84)
WAC 222-10-010
Policies and authorities.
(1) This chapteris promulgated pursuant to the authority granted in RCW 76.09.010, 43.21C.120 and chapter 197-11 WAC.
(2) The forest practices board, according to RCW 76.09.040,
possesses the authority to promulgate forest practices
((regulations)) rules establishing minimum standards for forest
practices and setting forth necessary administrative provisions.
(3) The forest practices board adopts by reference the policies of SEPA as set forth in RCW 43.21C.020.
(4) A ((Class IV-Special)) forest practices ((approval))
application or notification which requires a threshold
determination will be conditioned when necessary to mitigate
specific adverse impacts which are identified in the
environmental documents prepared under SEPA. An application
((for a Class IV-Special forest practice)) or notification will
be denied when the proposal would result in significant adverse
impacts identified in a final or supplemental environmental
impact statement prepared under SEPA, and reasonable mitigation
measures are insufficient to mitigate the identified impacts and
denial is consistent with all provisions of the acts cited in
subsection (1) of this section.
(5) SEPA policies and procedures ((required for
administration of Class IV-Special forest practices)) shall be
implemented by the department of natural resources.
[Statutory Authority: RCW 43.21C.120, 76.09.040 and 42.30.075. 84-18-021 (Order 429, Resolution No. 8-8-84), § 222-10-010, filed 8/29/84, effective 10/1/84; Order 258, § 222-10-010, filed 5/21/76.]
In addition to SEPA policies established elsewhere in this chapter, the following policies apply to forest practices described in WAC 222-16-050 (1)(d) relating to construction or harvest on potentially unstable slopes or landforms.
(1) In order to determine whether such forest practices are likely to have a probable significant adverse impact, and therefore require an environmental impact statement, the applicant must submit the following additional information, prepared by a qualified expert. The expert must describe the potentially unstable landforms in and around the application site, and analyze:
(a) The likelihood that the proposed forest practices will cause movement on the potentially unstable slopes or landforms, or contribute to further movement of a potentially unstable slope or landform;
(b) The likelihood of delivery of sediment or debris to any public resources, or in a manner that would threaten public safety; and
(c) Any possible mitigation for the identified hazards and risks.
(2) The department's threshold determination will include an evaluation of whether the proposed forest practices:
(a) Are likely to increase the probability of a mass movement on or near the site;
(b) Would deliver sediment or debris to a public resource or would deliver sediment or debris in a manner that would threaten public safety; and
(c) Such movement and delivery are likely to cause significant adverse impacts.
If the department determines that (a), (b) and (c) of this subsection are likely to occur, then the forest practice is likely to have a probable significant adverse impact.
(3) The department will evaluate the proposal, using appropriate expertise and in consultation with other affected agencies and Indian tribes.
(4) Specific mitigation measures or conditions must be designed to avoid accelerating rates and magnitudes of mass wasting that could deliver sediment or debris to a public resource or could deliver sediment or debris in a manner that would threaten public safety.
(5) Qualified expert for the purposes of this section means a person with a master's degree in geology or geomorphology or a related field, or a significant amount of postgraduate course or thesis work or other training in geomorphology or mass movement, and an additional 5 years of field experience in the evaluation of relevant problems in forested lands.
[]
When the department considers a watershed analysis for approval as in WAC 222-22-080, the department will perform a review under SEPA as a nonproject proposal. When making the threshold determination for a watershed analysis, the department shall only make a determination of significance if, when compared to rules or prescriptions in place at the time of the analysis or the 5-year review, the prescriptions will cause a probable significant adverse impact on elements of the environment other than those addressed in the watershed analysis process.

NEW SECTION
WAC 222-12-041
Use of approved state and federal
conservation agreements.
(1) Forest practices shall not be subject to forest practices rules in chapters 222-22 through 222-38 WAC pertaining to any species included within "aquatic resources" (as defined in WAC 222-16-010) if:
(a) The species is covered by an agreement listed below; and
(b) The issues covered by the forest practice rules are addressed in the agreement; and
(c) The forest practices are consistent with the agreement; and
(d) For an agreement listed in subsection (2)(a) or (b) of this section with a formal application date after July 1, 2001, the landowner has developed the related federal plan or management strategy in consultation with the department of fish and wildlife, the department of ecology, and affected Indian tribes.
(2) When a landowner submits a forest practice application or notification for an activity that is covered by one of the following agreements, the specific rules replaced will be identified by the landowner which the department will confirm at the time of approval. The agreements are:
(a) A habitat conservation plan and incidental take permit or an incidental take statement covering such species approved by the Secretary of the Interior or Commerce pursuant to 16 U.S.C. section 1536(b) or 1539(a) and reviewed under the National Environmental Policy Act, 42 U.S.C. section 4321 et seq.;
(b) An "unlisted species agreement" covering such species approved by the U.S. Fish and Wildlife Service or National Marine Fisheries Service which has been reviewed under the National Environmental Policy Act, 42 U.S.C. section 4321 et seq.; or
(c) Another cooperative or conservation agreement entered into with a state resource agency pursuant to its statutory authority for fish and wildlife protection, such as a landowner option plan, cooperative habitat enhancement agreement or a landscape management plan that addresses the needs of the aquatic resources and that is subject to review under the State Environmental Policy Act, chapter 43.21C RCW.
[]
The forest practices board recognizes and encourages collaborative efforts to build solutions to pressing forest practices issues. The forest practices board may at any time use this method to assist in assessing and recommending solutions to issues. The benefits of this method lie in the ability of disparate groups to use consensus processes to bring recommendations to the forest practices board. The board will continue to utilize collaborative efforts, such as the Timber, Fish, and Wildlife (TFW) forum. Participants would ideally consist of representation by timber interests, environmental interests, state agencies, local government, federal agencies, tribal governments and other interested parties so long as the collaborative effort utilizes a consensus approach to resolving or addressing issues.
[]
In order to further
the purposes of chapter 76.09 RCW the board has adopted a policy
of adaptive management designed to modify these ((regulations))
rules and their application based on cooperative research,
monitoring, and evaluation. Such adaptive management shall
include the measures set out in WAC 222-08-035. The forest
practices board, in consultation with Timber, Fish, and Wildlife
or a similar collaborative forum, will establish resource
objectives for "aquatic resources." (See definition in WAC 222-16-010.) The forest practices board will establish the
cooperative monitoring, evaluation, and research (CMER)
committee, and will, in consultation with TFW or a similar
collaborative forum, designate a scientific review committee.
(1) CMER. The CMER committee will conduct validation and effectiveness monitoring and research to facilitate achieving the resource objectives. Each funded project will have an independent scientific peer review performed or facilitated by the scientific review committee.
(a) Membership. The CMER committee will be made up of members representing timber interests, environmental interests, state agencies, local government, federal agencies and tribal governments who have expertise in the interaction of forest practices with public resources. CMER members will serve voluntarily without compensation or per diem.
(b) Administration. If funding is available, the department will employ an administrator to oversee the adaptive management program. The adaptive management program administrator will be selected in consultation with TFW or similar collaborative forum. The administrator will be responsible for managing the research and monitoring projects, including budget preparation and work plans, set time frames for products, and resolve disputes within the committee. In addition, the administrator will select peer reviewers in consultation with the scientific review committee.
(c) Reports to the board. The administrator will report to the forest practices board, at a minimum annually, on the membership of the CMER committee and on progress of funded projects. Each biennium, the administrator will submit the following for forest practices board approval: A budget proposal and a prioritized projects list that includes time frames for accomplishing the work. Both the budget and the projects list will have been developed in consultation with TFW or similar collaborative forum. This will be the basis for the department's biennial CMER budget request to the legislature. The department will conduct a performance audit of the expenditure of legislatively appropriated funds for CMER projects.
(2) Scientific review committee. A scientific review committee, chosen in consultation with TFW or similar collaborative forum, will be designated by the forest practices board to provide peer review of CMER's work. Together, the CMER and the scientific review committees will establish protocols and standards governing adaptive management including the review of pertinent external research and monitoring. The SRC will review or facilitate review of all studies, including design, methodology, data and results, presented to CMER in support of requests for changes to existing rules or suggestions for new rules.

When approved by the board the manual serves as an advisory technical supplement to these forest practices regulations. The department, in cooperation with the departments of fish and wildlife, agriculture, ecology, and such other agencies, affected Indian tribes, or interested parties as may have appropriate expertise, is directed to prepare, and submit to the board for approval, revisions to the forest practices board manual. The manual shall include:
(1) Method for determination of adequate shade requirements on streams needed for use with WAC 222-30-040.
(2) The standard methods for measuring ((channel width,
stream gradient and flow which are used in the water typing
criteria WAC 222-16-030)) physical parameters of streams and
channel migration zones.
(3) ((A chart for establishing recommended permanent culvert
sizes and associated data.)) Guidelines for forest roads.
(4) Guidelines for clearing slash and debris from Type 4 and 5 Waters.
(5) Guidelines for landing location and construction.

(14) Survey protocol for marbled murrelets. The Pacific seabird survey protocol in effect March 1, 1997, shall be used when surveying for marbled murrelets in a stand. Surveys conducted before the effective date of this rule are valid if they were conducted in substantial compliance with generally accepted survey protocols in effect at the beginning of the season in which they were conducted.
(15) The department shall, in consultation with the department of fish and wildlife, develop platform protocols for use by applicants in estimating the number of platforms, and by the department in reviewing and classifying forest practices under WAC 222-16-050. These protocols shall include:
(a) A sampling method to determine platforms per acre in the field;
(b) A method to predict the number of platforms per acre based on information measurable from typical forest inventories. The method shall be derived from regression models or other accepted statistical methodology, and incorporate the best available data; and
(c) Other methods determined to be reliable by the department, in consultation with the department of fish and wildlife.

Water typing system.
*The department in
cooperation with the departments of fish and wildlife, and
ecology, and in consultation with affected Indian tribes
((shall)) will classify streams, lakes and ponds and prepare
((stream classification)) water type maps showing the location of
((Type 1, 2, 3 and 4 Waters)) waters within the ((various))
forested areas of the state. ((Such)) The maps will be based on
a multiparameter, field-verified geographic information system
(GIS) logistic regression model. The multiparameter model will
be "habitat driven" and will use geomorphic parameters such as
basin size, gradient, elevation and other indicators.
Until the habitat-driven water type maps mentioned above are available, the current maps will continue to be used. These maps shall be available for public inspection at region offices of the department. The waters will be classified using the following criteria. If a dispute arises concerning a water type the department shall make available informal conferences, which shall include the departments of fish and wildlife, and ecology, and affected Indian tribes and those contesting the adopted water types. These conferences shall be established under procedures established in WAC 222-46-020.
*(1) "Type 1 Water" means all waters, within their ordinary high-water mark, as inventoried as "shorelines of the state" under chapter 90.58 RCW and the rules promulgated pursuant to chapter 90.58 RCW, but not including those waters' associated wetlands as defined in chapter 90.58 RCW.
*(2) "Type 2 Water" ((shall)) means segments of natural
waters which are not classified as Type 1 Water and have a high
fish, wildlife, or human use. These are segments of natural
waters and periodically inundated areas of their associated
wetlands, which:
(a) Are diverted for domestic use by more than 100 residential or camping units or by a public accommodation facility licensed to serve more than 100 persons, where such diversion is determined by the department to be a valid appropriation of water and the only practical water source for such users. Such waters shall be considered to be Type 2 Water upstream from the point of such diversion for 1,500 feet or until the drainage area is reduced by 50 percent, whichever is less;
(b) Are diverted for use by federal, state, tribal or private fish hatcheries. Such waters shall be considered Type 2 Water upstream from the point of diversion for 1,500 feet, including tributaries if highly significant for protection of downstream water quality. The department may allow additional harvest beyond the requirements of Type 2 Water designation provided the department determines after a landowner-requested on-site assessment by the department of fish and wildlife, department of ecology, the affected tribes and interested parties that:
(i) The management practices proposed by the landowner will adequately protect water quality for the fish hatchery; and
(ii) Such additional harvest meets the requirements of the water type designation that would apply in the absence of the hatchery;
(c) Are within a federal, state, local, or private campground having more than 30 camping units: Provided, That the water shall not be considered to enter a campground until it reaches the boundary of the park lands available for public use and comes within 100 feet of a camping unit, trail or other park improvement;
(((c))) (d) Are used by substantial numbers of ((anadromous
or resident game)) fish for spawning, rearing or migration. Waters having the following characteristics are presumed to have
highly significant fish populations:
(i) Stream segments having a defined channel 20 feet or
greater ((in width between the ordinary high-water marks)) within
the bankfull width and having a gradient of less than 4 percent.
(ii) Lakes, ponds, or impoundments having a surface area of 1 acre or greater at seasonal low water; or
(((d))) (e) Are used by salmonids for off-channel habitat. These areas are critical to the maintenance of optimum survival
of juvenile salmonids. This habitat shall be identified based on
the following criteria:
(i) The site must be connected to a stream bearing salmonids and accessible during some period of the year; and
(ii) The off-channel water must be accessible to juvenile salmonids through a drainage with less than a 5% gradient.
*(3) "Type 3 Water" ((shall)) means segments of natural
waters which are not classified as Type 1 or 2 Water and have a
moderate to slight fish, wildlife, and human use. These are
segments of natural waters and periodically inundated areas of
their associated wetlands which:
(a) Are diverted for domestic use by more than 10 residential or camping units or by a public accommodation facility licensed to serve more than 10 persons, where such diversion is determined by the department to be a valid appropriation of water and the only practical water source for such users. Such waters shall be considered to be Type 3 Water upstream from the point of such diversion for 1,500 feet or until the drainage area is reduced by 50 percent, whichever is less;
(b) Are used by significant numbers of ((anadromous)) fish
for spawning, rearing or migration. ((Waters having the
following characteristics are presumed to have significant
anadromous fish use:
(i) Stream segments having a defined channel of 5 feet or greater in width between the ordinary high-water marks; and having a gradient of less than 12 percent and not upstream of a falls of more than 10 vertical feet.
(ii) Ponds or impoundments having a surface area of less than 1 acre at seasonal low water and having an outlet to an anadromous fish stream.
(c) Are used by significant numbers of resident game fish. Waters with the following characteristics are presumed to have significant resident game fish use:))
The requirements for determining fish use are described in the board manual section 13. If fish use has not been determined:
(i) Waters having the following characteristics are presumed to have fish use:
(A) Stream segments having a defined channel of ((10)) 2
feet or greater ((in width between the ordinary high-water marks;
and a summer low flow greater than 0.3 cubic feet per second;))
within the bankfull width in Western Washington; or 3 feet or
greater in width within the bankfull width in Eastern Washington;
and having a gradient of ((less than 12)) 16 percent or less.
(((ii))) (B) Stream segments having a defined channel of 2
feet or greater within the bankfull width in Western Washington;
or 3 feet or greater within the bankfull width in Eastern
Washington, and having a gradient greater than 16 percent and
less than or equal to 20 percent, and having greater than 50
acres in contributing basin size in Western Washington or greater
than 175 acres contributing basin size in Eastern Washington,
based on hydrographic boundaries;

(D) Ponds or impoundments having a surface area greater than
0.5 acre at seasonal low water((; or)).
(((d) Are highly significant for protection of downstream
water quality. Tributaries which contribute greater than 20
percent of the flow to a Type 1 or 2 Water are presumed to be
significant for 1,500 feet from their confluence with the Type 1
or 2 Water or until their drainage area is less than 50 percent
of their drainage area at the point of confluence, whichever is
less.)) (ii) The department shall waive or modify the
characteristics in (i) of this subsection where:
(A) Waters have confirmed, long term, naturally occurring water quality parameters incapable of supporting fish;
(B) Snowmelt streams have short flow cycles that do not support successful life history phases of fish. These streams typically have no flow in the winter months and discontinue flow by June 1; or
(C) Sufficient information about a geographic region is available to support a departure from the characteristics in (i) of this subsection, as determined in consultation with the department of fish and wildlife, department of ecology, affected tribes and interested parties.
*(4) "Type 4 Water" ((classification shall be applied to
segments of natural waters which are not classified as Type 1, 2
or 3, and for the purpose of protecting water quality downstream

becomes less than 2 feet in width between the ordinary high-water
marks. Their significance lies in their influence on water
quality downstream in Type 1, 2, and 3 Waters. These may be
perennial or intermittent.)) means all segments of natural waters
within the bankfull width of defined channels that are not Type
1, 2 or 3 Waters and which are perennial waters of
nonfish-bearing streams. Perennial waters means waters
downstream from a perennial initiation point. (See board manual,
section 13, for the protocol for defining the upper extent of a
perennial stream.)
*(5) "Type 5 Waters" ((classification shall be applied to
all natural waters not classified as Type 1, 2, 3 or 4; including
streams with or without well-defined channels, areas of perennial
or intermittent seepage, ponds, natural sinks and drainageways
having short periods of spring or storm runoff.)) include all
segments of natural waters within the bankfull width of defined
channels that are not Type 1, 2, 3 or 4 Waters and which are
seasonal nonfish bearing streams. "Seasonal stream" means those
streams that are not perennial but are physically connected by a
defined channel system to downstream waters so that water or
sediment initially delivered to these waters may eventually be
delivered to a Type 1, 2, 3 or 4 Water.
*(6) For purposes of this section:
(a) "Residential unit" means a home, apartment, residential condominium unit or mobile home, serving as the principal place of residence.
(b) "Camping unit" means an area intended and used for:
(i) Overnight camping or picnicking by the public containing at least a fireplace, picnic table and access to water and sanitary facilities; or

*The department in
cooperation with the departments of fish and wildlife, and
ecology, and affected Indian tribes shall classify wetlands. The
wetlands will be classified in order to distinguish those which
require wetland management zones and those which do not. Wetlands which require wetland management zones shall be
identified using the following criteria. ((Accurate delineation
of wetlands in accordance with the manual shall be required only
where necessary to determine whether replacement by substitution
or enhancement is required pursuant to WAC 222-24-025(10) and
shall be limited to the area of wetland proposed to be filled. For the purposes of determining acreage to classify or type
wetlands under this section, approximate determination using
aerial photographs and maps, including the national wetlands
inventory, shall be sufficient. In addition, the innermost
boundary of the wetland management zone on Type A or B wetlands
may be determined by either of two methods
