Resources Agency's Response to NMFS
California Forest Practice Rules
July 10, 1998
The California Resources Agency has reviewed a "Draft" titled "Effectiveness of the California Forest Practice Rules to Conserve Anadromous Salmonids". The document makes extensive reference to various sections of the California Forest Practice Rules (FPR), Title 14, California Code of Regulations (CCR). Taken in isolation the individual sections of the rules may not appear to provide adequate protection for watercourses or the habitat and species that rely on watercourses. California relies on an adaptive management approach in regulating timber harvesting. This approach weighs heavily on mitigating any significant adverse impact on environmental resources. It is a process that allows the reviewing agencies to ask the question "How is coho being protected?" and ends up with a plan that fully protects the species and its habitat. A commonly referred to compilation of the rules prepared by the California Department of Forestry and Fire Protection (CDF) for California Timber Operators, January 1998, contains 211 pages of text in relatively small print. It is difficult for anyone unfamiliar with this volume of material to scan these pages and glean a complete picture of all the avenues available to the review agencies for the protection of the varied resources of California.
Please note that the rules are applied to a wide variety of possible conditions. These rules apply to a landowner with ten acres of flat ground with no watercourses, archaeological sites, or other constraints, as well as to the large industrial timberland owners with many watersheds to manage, listed species, many watercourses, archaeological sites, erosion sources predating the current FPRs, and numerous other constraints. Regulation of timber harvesting on private and state-owned lands in California occurs under the Z'berg-Nejedly Forest Practice Act of 1973 (FPA). The nine member Board of Forestry (BOF) adopts regulations under authority of the FPA, and CDF administers those rules.
The FPA is intended to regulate timberlands to achieve two goals: (1) to enhance, restore and maintain the productivity of timberland wherever feasible; and (2) to achieve maximum sustained production of high-quality timber while giving consideration to values relating to recreation, watershed, wildlife, range and forage, fisheries, regional economic vitality, employment and aesthetic enjoyment.
Because the approval of individual timber harvest plans (THP) by CDF involves the exercise of discretion and judgment and because the timber harvesting has the potential to affect the environment, the California Environmental Quality Act (CEQA) applies to the process also. This act is similar to the National Environmental Policy Act (NEPA) and requires analysis of the environmental effects of individual projects and of alternatives and mitigation measures to avoid or lessen any significant environmental effects of the project.
CEQA requires that public agencies not approve a project as proposed if there are feasible alternatives or feasible mitigation measures available which would substantially lessen the significant environmental effects of the project. The applicant must disclose and identify the significant effects of a project for state agency and public review.
The FPA emphasizes decision making based on the rules. The FPRs have been evolving over the last 23 years in response to changing environmental considerations. CEQA, in contrast, emphasizes case-by-case, open-ended analysis of environmental impacts, alternatives, and mitigation measures. The review of THPs is a melding of the two processes. This results in an adaptive management process where any issue that is raised such as protection of the coho must be discussed, and if a significant adverse impact is found, CDF is required to mitigate to a level of insignificance. If the action cannot be mitigated to insignificance, CDF may disapprove the plan or approve the plan with overriding considerations. In the case of a listed species, overriding considerations is not an option.
Through this process the Registered Professional Forester (RPF), with the help of appropriate professionals develops the THP that they believe will not have a significant effect on environmental resources. Normally, it has more than the rule minimums as protection for environmental resources. CDF and the review team agencies review the RPF's work and make their independent judgment on whether the plan, with mitigation will in fact not have a significant effect on environmental resources. This adaptive management process allows the RPF and review agencies to adapt the plan to provide for the needs of fish, as new information surfaces.
The question is how well does all this work to protect coho and other resources? The state is working towards an effective monitoring program. Throughout this document some preliminary results are reported.
A Monitoring Study Group (MSG) was formed by the BOF in 1989 to develop a Long Term Monitoring Program (LTMP) for assessing the effectiveness of the FPRs in protecting water quality. The group is made up of members of the public, resource agencies and the timber industry. Several projects have been carried out over the past five years that have allowed the LTMP to proceed.
The primary objective of the LTMP is to provide an ongoing assessment of the effectiveness of the FPRs, as implemented, in protecting beneficial uses of water (i.e., coldwater fisheries and domestic water supplies) through implementation, effectiveness, and project monitoring.
The LTMP results will be provided to the BOF and the public in a timely manner to contribute effectively to BOF's program for reviewing and, where necessary, strengthening the rules' performance and best management practices (BMP).
The LTMP has an in-stream and hillslope component. The first year of data collection on the hillslope component was completed in 1996 on THPs. The data collection continues on another 50 THPs in 1997. A summary of the 1996 data should be available later this year.
CDF is developing a compliance monitoring form for use during the mandatory completion inspection on each THP. Trend monitoring will be the responsibility of the Department of Fish and Game (DFG).
A good example of the state's monitoring program is south of San Francisco. The listing of coho in that area by the state initiated a process to address timber harvesting and its effect on coho. This process includes compliance, effectiveness, and trend monitoring. Compliance monitoring is done by the state's forest practice inspectors. Effectiveness is reported by the private RPF and trend monitoring is done by DFG. Results of this monitoring will assist in fine tuning the process to assume all concerned that timber harvesting is protecting coho and other resources.
The following is the Agency's response to each of the items of concern found in the draft document. The response to the first section "General Concerns" contains additional summary material, concerning mainly the preparation and review process associated with THPs. The material in italic print has been copied directly from the National Marine Fisheries Service (NMFS) document. Each section is followed by a response printed in plain block lettering.
General Concerns
Two areas of concern that the National Marine Fisheries service has with the implementation of the California Forest Practice Rules relate to the large number of rules under which adequate conservation for anadromous salmonids depends heavily on the Registered Professional Forester (RPF) having a high level of biological, ecological, and/or geological expertise. It is unrealistic to expect all RPFs have such knowledge. Often, the conservation of ecological resources, including anadromous salmonids, depends upon protective measures that are inserted into Timber Harvesting Plans (THPs) during the review process. Two state agencies, the California Department of Fish and Game (CDFG) and the Regional Water Quality Control Board (RWQCB) have been given statutory responsibility to review THPs for compliance with the California Fish and Game Code and Clean Water Act, respectively. The Division of Mines and Geology also reviews THPs. No integrated guidelines or policies are available to provide a framework for treatment of THPs through the review process (Little Hoover Commission 1994). In addition, the agencies can review only a small fraction of the THPs, and thus are forced to rely on RPFs, not agency personnel, to determine problems and design mitigation measures. Furthermore, even when these agencies participate in a review, there is no requirement that the agencies recommendations must be incorporated into THPs.
Response: This passage has overlooked the role CDF plays in the review process of THPs. Within this Department every plan goes through several levels of review by agency personnel.
Prior to a plan being submitted to CDF, it is prepared by RPF. California requires its professional foresters to register and obtain a license to practice. To be eligible for a license, a candidate must have at least seven years of experience in forestry and must pass a comprehensive examination. In the preparation of a THP, the RPF must include a description of the site to be harvested, the types of timber operations to be conducted, and mitigation measures to be used consistent with BOF rules. Also included must be information concerning silvicultural systems, yarding methods, reforestation methods, erosion control methods, stream protection, road building, and erosion hazard rating. The RPF must conduct a field investigation to apply the rules with respect to watercourse classification and protection measures, location of sensitive terrain, and development of appropriate mitigation measures or alternatives. From the DFG the RPF may obtain, if necessary, a "No Take" document regarding the northern spotted owl or marbled murrelet, a Streambed Alteration Permit, and/or a listing of species of wildlife likely to be in the area from the Natural Diversity Data Base. The RPF is required by the Forester's Licensing Law to consult with other experts when the RPF does not have the required expertise. RPFs do consult with wildlife or fisheries biologists, botanists, geologists, engineers, or other resource professionals regarding various facets of the plan. The state is offering to RPFs and agency staff a four-day watershed academy to impart (or review) specific hands-on skills that RPFs can use to improve THPs and monitoring from a watershed/fisheries perspective. Skills will include learning to recognize potential mass wasting problems from air photos and ground conditions, geomorphic features of both healthy and damaged aquatic habitat, good and bad crossing placement and design, and when to call in more expertise. The course will increase the students' awareness and knowledge of watershed processes and values and increase their awareness of how their actions can effect the processes and values.
When a plan is submitted, CDF immediately initiates review. Title 14 CCR 1037 states: "Within ten (10) days of the receipt of a plan, the Director shall determine if the plan is accurate, complete and in proper order " In the Santa Rosa Headquarters office (responsible for the review of all plans in the Coast Forest District which runs from the Oregon border to Santa Cruz County described in detail in 14 CCR 907) there are two full-time staff foresters. Each of these foresters and their supervisor are RPFs. These individuals have had many years of experience reviewing THPs. They are familiar with which watersheds in the Coast Forest District have required additional protections for a variety of resources in the past, and items which might indicate the need for additional information or protective measures. The other Forest Districts have similar arrangements. Title 14 CCR 1037 continues, stating "When the Director finds a plan inaccurate, incomplete or otherwise not in proper order, the plan shall be returned to the submitter with written specifications of the deficiencies." A plan can be returned to the RPF for corrections or additional information two or three times before it is found to be accurate, complete and in proper order for filing. Once accepted for filing the plan is sent to DFG, WQ, Division of Mines and Geology (DMG) and any interested public. These agencies paper review nearly 100% of the plans and pass on their concerns and question to the review team.
With this first hurdle passed, a multidisciplinary review team conducts the first review team meeting to assess the plan. The review team normally consists of, but is not necessarily limited to, representatives of CDF, DFG, and the WQ. DFG and WQ may choose to participate in this meeting by sending a list of concerns or questions about the plan via fax, email, or telephoning the review team chair prior to the meeting.
The purpose of the first review team meeting is to assess the proposed logging plan and determine on a preliminary basis, whether it conforms to the rules of the BOF. If a plan is very simple with a very low potential for environmental impacts, it may be determined that a field inspection (preharvest inspection) is not necessary. However, it is generally the case that questions arise at the review team meeting. Some of these questions are returned to the RPF who prepared the plan for response. Others are formulated which are to be answered by a field inspection team. The nature of the questions raised and interest of the various agencies results in a list of agencies that will be contacted to attend the preharvest inspection.
The DMG also reviews each THP for indications of potential slope instability, and other potential geologic concerns. The Santa Rosa Headquarters office has two DMG staff members. Each of these is a Certified Engineering Geologist. Each harvest plan filed is routed to one of these geologists who indicate whether a field geologic evaluation should be required during the preharvest inspection. In the Coast Forest District, there are four Mines and Geology Certified Engineering Geologists, two in Santa Rosa and one each in Mendocino and Humboldt Counties. All four of these geologists work primarily with the evaluation of THPs. Of the 520 plans submitted in the Coast Forest District in 1997, there were 131 Engineering Geological Reviews. For each of the reports, at least one of the four geologists mentioned above had visited the plan area on at least one occasion.
Next, a pre-harvest inspection (PHI) is normally conducted to examine the THP area and the logging plan. All review team members may attend, as well as other experts and agency personnel whom CDF may request. CDF has on staff several specialists who may also attend PHIs. There are two wildlife biologists stationed within the Coast Forest District, one in Santa Rosa and one in Fortuna in Humboldt County. In Sacramento and/or Redding, CDF has a hydrologist, entomologist, plant pathologist, as well as additional wildlife biologists and other resource specialists who can be called upon for plan review. CDF's biologists are normally not called on to participate in a PHI unless DFG cannot attend and there is a pressing fisheries or wildlife issue.
As a result of the PHI, additional recommendations may be formulated for site-specific conditions to ensure environmental protection, or additional questions raised that are directed to the RPF who prepared the plan. Questions raised during the first review team meeting to be answered by the field inspection team are answered in field inspection reports prepared by CDF and any other agencies that may have attended the field inspection.
After a PHI, a second review team meeting is conducted to examine the field inspection reports and to finalize any additional recommendations or changes in the THP. The review team chairperson transmits these recommendations to the RPF who developed the harvesting plan. The RPF must address and respond to each recommendation. To reach a decision on approval or denial of a proposed plan, the Director's representative considers public comment, the adequacy of the RPF's response, the recommendations of the review team chairperson, and the legal authority of the FPA/FPRs and CEQA before reaching a decision to approve or deny a plan. CEQA and its substantive criteria for the evaluation of a proposed project's environmental impact apply to the timber harvesting and must be melded with the FPA/FPRs when making a decision on the plan.
If a participating agency has a recommendation that the review team chairperson (CDF) did not include in the final list of recommendations, there are measures that the agency can take. The first action that can be taken is to file a non-concurrence. This is described in 14 CCR 1037.5(e):
A higher level of action that can be taken by the State Water Resources Control Board or the Director of DFG would be a Head of Agency Appeal, 14 CCR 1056. This must be filed no later than ten days from the date of THP approval. 14 CCR 1056.1 to CCR 1056.6 discuss the steps of this process in detail.
Before commencing operations, the plan submitter must notify CDF. During operations, CDF periodically inspects the logging area for compliance with the specifications of the THP and for compliance with the FPRs. The number of the inspections will depend upon the plan size, duration, complexity, regeneration method, and the potential for impacts. The contents of the THP and the FPRs provide the criteria CDF inspectors use to determine if violations exist. While CDF cannot guarantee that a violation will not occur, it is CDF's policy to pursue vigorously the prompt and positive enforcement of the FPA, the FPRs, related laws and regulations, and environmental protection measures applying to timber operations on the non-Federally owned lands in California. This enforcement policy is directed primarily at preventing and deterring forest practice violations and secondarily at prompt and adequate correction of violations when they occur. The mitigation measures required or incorporated in this THP will be monitored during the inspections conducted by CDF as authorized or required by the FPA [Public Resources Code (PRC) 4513-4628]. The inspections include but are not limited to inspections during operations pursuant to PRC 4604, inspections of completed work pursuant to PRC 4586, erosion control auditing as per PRC 4585(a), and stocking inspections pursuant to PRC 4588.
Most forest practice violations are correctable and CDF's enforcement program assures correction. Where non-correctable violations occur, criminal action is taken. Depending on the outcome of the case and the court in which the case is heard, environmental corrective work is done. This is intended to offset non-correctable adverse impacts.
Once harvesting operations are finished, a completion report must be submitted certifying that the area meets the requirements of the rules. CDF inspects the area to verify that all aspects of the applicable rules and regulations have been followed, including erosion control work. A prescribed maintenance period begins once CDF has approved the completion report.
Specific Concerns
895.1 Definitions
Abandonment means leaving a logging road reasonably impassable to standard production four wheel-drive highway vehicles, and leaving a logging road and landings in a condition which provides for long-term functioning of erosion controls with little or no continued maintenance.
Analysis
Potential Biological Impacts
Response: The definition is just that, a statement of the meaning of a word or group of words used elsewhere in the rules, it is not an enforceable standard. The appropriate rules regarding enforceable standards associated with the abandonment of roads is 14 CCR 923.8 [943.8, 963.8]:
The above rule requires that surface erosion be minimized during and following the abandonment of a road. Where a road to be abandoned is near a watercourse, there may be chronic erosion associated with leaving the road in place, abandonment may result in a decrease in material being delivered to the watercourse.
Complete closure of a road may not be physically possible. Horses and bicycles in particular as well as some of the all terrain vehicles (ATVs) available today can easily navigate areas where there have never been any roads. However, as seen in the rule language cited above, road and landings surfaces as well as fills and sidecast may be reshaped to promote drainage. Crossings are to be removed. This would also minimize the remaining level surface for travel by later users.
It should be noted that the majority of THPs are on private property, either owned by one or more citizens or by a commercial landowner. Most of these ownerships are not open to the public for recreation. What limited use by horses, bikes and off-road vehicles that might take place is generally done by trespassers and not encouraged by the landowner(s).
It is true that the definition does not require removal of all road features that may reroute hillslope drainage, restrict or confine stream flow, and/or present slope stability hazards (culverts, cross drains, inside ditches) but the provisions of the rule quoted above do. Likewise the stream crossing structures that may become degraded over time or may become perched, blocked, or wash out are also generally removed as per the rule quoted above.
The term of a THP is generally three years (five years maximum if extended). Once a plan has been completed a maintenance period begins. 14 CCR 914.6 [934.6, 954.6] (h) and (i) addresses this (emphasis added):
(I) The prescribed maintenance period for waterbreaks and any other erosion control facilities on skid trails, cable roads, layouts, firebreaks, abandoned roads, and site preparation areas, shall be at least one year. The Director may prescribe a maintenance period extending as much as three years after filing of the work completion report in accordance with 14 CCR 1050."
14 CCR 1050 also addresses the maintenance period:

Canopy means the more or less continuous cover of branches and foliage collectively by the crowns of adjacent trees and other woody species.
Analysis
Potential Biological Impacts
Shade canopy retention has been monitored by CDF on completed harvest operations by field inspectors and audit inspectors. In a letter to the Executive Officer of BOF (Anthony, 1997) shade canopy on class I (fish bearing) watercourses was reported to average
82.6 percent. The measurements were taken using a canopy measuring instrument and represents percent of total shade covering the surface of the ground at the point of measurement. Similar results have been reported from preliminary data collected as part of the state's Long Term Monitoring Program (LTMP). It is interesting to note these operations audited where completed before CDF issued their coho consideration document.

895.1 Definitions
Late Succession Forest Stands means stands of dominant and predominant trees that meet the criteria of WHR class 5M, 5D, or 6 with an open, moderate or dense canopy closure classification, often with multiple canopy layers, and are at least 20 acres in size.
Analysis
Potential Biological Impacts
Response: This definition is used to screen for stands with certain characteristics to allow specific wildlife protection measures to be applied. It is true that some stands which may receive the "late succession" classification may not exhibit all of the characteristics desired by any one group or agency or that would provide optimal habitat for all species dependent upon late succession forest stands.
See the response to the discussion regarding 14 CCR 916.5 [936.5, 956.3] and the topic of canopy retention and monitoring. Shade canopy retention has been monitored by CDF on completed harvest operations by field inspectors and audit inspectors. In a letter to the Executive Officer of the BOF (Anthony, 1997) shade canopy on class I (fish bearing) watercourses were reported to average 82.6 percent.
Once a stand has been identified as a late succession forest stand there are specific rules which must be applied. These rules allow for the protection of functional wildlife habitat. 14 CCR 919.16 [939.16, 959.16] addresses the protection of wildlife resources in late succession stands:

895.1 Definitions
Past Projects means previously approved, on-going, or completed projects which may add to or lessen impact(s) created by the THP. These generally include, but may not be limited to, projects completed within the last ten years.
Projects are activities which have the potential to cause a physical change in the environment, directly or ultimately, and that is: 1) undertaken by a public agency, or 2) undertaken with public agency support, or 3) requires the applicant to obtain a lease, permit, license, or entitlement from one or more public agencies.
Analysis
Potential Biological Impacts
The lack of a complete analysis of all past projects that may be contributing towards cumulative impacts may lead to an incorrect determination of cumulative watershed effects (CWEs). CWEs associated with forest practices and natural processes affect geomorphological processes and products in watersheds. Changes in inputs such as wood, water, sediment, and shade can impact biological communities through:
Response: This concern actually combined two definitions. The definition of Projects above is incomplete. An additional sentence in the definition is "This includes Timber Harvesting Plans."
CEQA and its substantive criteria for the evaluation of a proposed project's environmental impact apply to the evaluation of watershed resources. Within Technical Rule Addendum No.2 (an addendum to the FPRs) there is also a detailed section addressing the evaluation of watershed resources. Evaluation of the conditions listed in this section, as part of the cumulative impacts assessment, identify the impacts from past activities even if the activities themselves were not specified. That section states:

895.1 Definitions
Permanent Watercourse Crossing means a watercourse crossing that will be constructed to accommodate the estimated fifty-year flood flow and will remain in place when timber operations have been completed.
Analysis
Potential Biological Impacts
It should be noted that 14 CCR 923.3 [943.3, 963.3] requires, "Drainage structures on watercourses that support fish shall allow for unrestricted passage of fish." And "Permanent watercourse crossings and associated fills and approaches shall be constructed or maintained to prevent diversion of stream overflow down the road and to minimize fill erosion should the drainage structure become obstructed. "
14 CCR 923.1(b) [943.1(b), 963.1(b)] states that, "New logging roads shall be planned in accordance with their classification and maintenance requirements." Logging roads would include those crossings necessary in the system.
Furness (1991) recommends designing drainage structures to accommodate peak streamflow based on at least a 50-year-interval flood. Trying to design crossings that will never fail is likely doomed for failure. The use of the 50-year design criteria balances economic and resource protection. In addition, 14 CCR 923.3 requirements are there if the unforeseen happens.
Specific Concerns
895.1 Definitions
Prescribed Maintenance Period means the period during which erosion controls which are required and constructed as part of a timber operation must be maintained in a functional condition. The period shall not exceed three years.
Analysis
Potential Biological Impacts
Other sections of the FPRs require construction, reconstruction, and abandonment of roads and associated drainage structures to minimize maintenance requirements (discussed elsewhere in this document in greater detail). Temporary logging roads must be abandoned with self-maintaining erosion controls upon completion of timber operations. On seasonal logging roads, watercourse crossings must be removed and erosion controls installed before the beginning of each winter period during the period of timber operations and upon completion. Waterbars tend to stabilize over time if the road or skid trail is not in use. If in use, a permanent logging road is most likely used for other land management activities and/or other harvest plans. In the latter case, it would be subject to overlapping operational and prescribed maintenance periods. Most logging roads are on private property and not readily accessible to the general public after harvest operations have been completed.
See discussion in the response to 895.1 Definitions, Abandonment regarding the proper decommissioning of roads and requirements that reduce the potential for altering hillside drainage, intercepting, diverting, and concentrating surface and subsurface flow.

Saturated Soil Conditions means 1) the wetness of the soil within a yarding area such that soil strength is exceeded and displacement from timber operations will occur. It is evidenced by soil moisture conditions that result in: a) reduced traction by equipment as indicated by spinning or churning of wheels or tracks in excess of normal performance, or b) inadequate traction without blading wet soil or, c) soil displacement in amounts that cause visible increase in turbidity of the downstream waters in a receiving Class I or II watercourse or lake. Soils frozen to a depth sufficient to support equipment weight are excluded. 2) soil moisture conditions on roads and landings, in excess of that which occurs from normal road watering or light rainfall that will result in the significant loss of surface material from the road and landings in amounts that cause visible increase in turbidity of the downstream waters in receiving Class I or II watercourse or lake.
Analysis
Potential Biological Impacts
14 CCR 923.6 [943.6, 963.6] Conduct of Operations on Roads and Landings, includes reference to a indicator of saturated soil conditions and criteria for when operations may take place. The code section states (emphasis added):
The "visible increase in turbidity" was added to the rules as a guide to the timber operator. It is best used in the early portion of storms and as the waters begin to recede. During these times an increase in turbidity can be seen and operations are to cease.

895.1 Definitions
Watercourse or Lake Transition Line means that line closest to the watercourse or lake where riparian vegetation is permanently established.
Analysis
Response: The definition does not rely on the watercourse or lake being watered at the time the measurement is taken. The key phrase is "riparian vegetation" for establishing this line. Riparian vegetation is likely to be present over much of valley bottoms with wide floodplains where streams are very sinuous and in low flow or remnant channels where water may not be present. In addition, low flow or remnant channels would be likely to show evidence of being wet at some portion of the year, requiring some form of protection.
Wide valley bottoms with wide floodplains where streams are very sinuous and migration of the channel is common generally have a wide expanse of gravel, cobbles or other loose material and do not support mature trees over much of the floor of the valley due to the mobile nature of the substrate. The transition line here would be where the vegetation is established at the edge of this mobile material, and there would likely be little conifer within this floodplain. Where conifers grow within the floodplain, Watercourse and Lake Protection Zones (WLPZ) protections will assure retention of forest conditions. Should the stream migrate so will future WLPZs.
14 CCR 916.4(b)(5) [936.4(b)(5), 956.4(b)(5)] allows for a wider zone under certain conditions, one of which is hydrologic considerations:
14 CCR 916.4 (a), 936.4(a), 956.4(a) address this issue by requiring the RPF to identify and propose mitigation for floodprone areas and changeable channels. Elsewhere in the rules, the transition line is used to describe where remedial measures are required during harvest operations. 14 CCR 916.3 (a), (b) [936.3(a),(b), 956.3(a),(b)] state:
While "riparian vegetation" is not a specific definition in the FPRs, this type of vegetation is alluded to in the definition of "Riparian" in 14 CCR 895.1; "Riparian means the banks and other adjacent terrestrial environs of lakes, watercourses, estuaries, and wet areas, where transported surface and subsurface freshwaters provide soil moisture to support mesic vegetation."
Off-channel rearing habitat would be classified as class I watercourses, due to the presence of fish, and would be provided the appropriate protections.

A possible definition of significant rain could be 0.5 in. rain in a 24 hour period as forecast by the US Weather Service."
"The RPF should write a wet weather road use plan to guide the actions of the timber operator before, during and shortly after periods of precipitation. It should address road use that is capable of altering the surface including site preparation. The plan should consider the condition of the buffer between roads and watercourses within and appurtenant to the THP (width, slope, and post-harvest filtering capacity), the condition of the road (grade, soil type, surfacing, and level of use following completion of harvest), and the ability of the road as designed and operated to deliver sediment and elevate water discharge into coho habitat. At a minimum, the road use plan might discuss the following for maintaining water quality:
14 CCR 914.6 [934.6, 954.6](a) and (b), Waterbreaks states; "All waterbreaks shall be installed no later than the beginning of the winter period of the current year of timber operations " and "Waterbreaks shall be constructed concurrently with the construction of firebreaks and immediately upon conclusion of use of tractor roads, roads, layouts, and landings which do not have permanent and adequate drainage facilities, or drainage structures." At any given time of the year, only the area currently being harvested should be in need of drainage structures if a significant rainfall event were to occur. Half an inch of rain during the summer when soils can accommodate the moisture would be different than the same half an inch of rain when the soils are already at field capacity [saturated]. (Half an inch in half an hour is different than half an inch in a day.)
Stream crossing construction, especially in a watercourse where salmon have spawned, would require a permit from DFG. The emergence of juveniles from the gravels would be considered.
14 CCR 915.1 [935.1, 955.1](b) states; "Heavy equipment shall not be used for site preparation under saturated soil conditions or when it cannot operate under its own power due to wet conditions." This is regardless of the time of year.
Specific Concerns
898 Feasibility Alternatives
After considering the rules of the Board and any mitigation measures proposed in the plan, the RPF shall indicate whether the operation would have any significant adverse impact on the environment. On TPZ lands, the harvesting per se of trees shall not be presumed to have a significant adverse impact on the environment. If the RPF indicates that significant adverse impacts will occur, the RPF shall explain in the plan why any alternatives or additional mitigation measures that would significantly reduce the impact are not feasible.
Cumulative impacts shall be assessed based upon the methodology described in Board Technical Rule Addendum Number 2, Forest Practice Cumulative Impacts Assessment Process and shall be guided by standards of practicality and reasonableness. The RPF's and plan submitter's duties under this section shall be limited to closely related past, present and reasonably foreseeable probable future projects within the same ownership and to matters of public record. The Director shall supplement the information provided by the RPF and the plan submitter when necessary to insure that all relevant information is considered.
Analysis
Impacts of cumulative watershed affects on fisheries resources and aquatic communities include:
CDF is not bound by the decision and justification provided by the RPF regarding the assessment of cumulative impacts. 14 CCR 898.1, Review of Plan by Director, states (emphasis added):

912.5 Procedure for Estimating Surface Soil Erosion Hazard Rating [Coast]
A proposed plan shall show the estimated erosion hazard ratings of the plan area, by areas, down to 20 acres (8.1 ha) if such a breakdown will change the estimated erosion hazard of individual areas. The plan shall show high and extreme erosion hazard ratings, by areas, down to 10 acres if such a breakdown will change the erosion hazard of the individual areas. Specific erosion hazard areas not fitting the above minimum will be considered independently and protective measures commensurate with the problem applied. These measures are covered in Chapter 4, Subchapter 4 of Title 14 CCR.
To estimate the erosion hazard rating of any plan or portion thereof, the RPF or supervised designee shall follow the procedures and requirements contained in Board Technical Rule Addendum #1, dtd. February 1, 1990. Approximate weights for the factors in the Estimated Surface Soil Erosion Hazard, Form I, in the Addendum, shall be calculated and the factors shall be summed to five the rating. A copy of the calculations from Form I shall be attached to the Timber Harvesting Plan.
Analysis
Response: This rule provides the direction for determining the erosion hazard ratings which are required to be included in the plan. The rule refers to Board Technical Rule Addendum #1. While some level of subjectivity is present in the rating system, the Technical Rule Addendum contains very specific direction for determining soil texture, detachability and depth to restrictive layer or bedrock. Surface coarse fragments including rocks or surface stones, slope factor, and vegetative cover are factors that can be measured or estimated with little difficulty and do not need expansive explanation. The rainfall intensity value is derived from maps provided in the Technical Rule Addendum, maps taken from Technical Paper No. 28, U.S. Weather Bureau, or can be derived from more localized information if available.
Although the Erosion Hazard Rating (EHR) methodology can be described as simplistic, and results are subjective, all the major factors causing and resisting surface erosion have been considered and the rating can be expected to perform as well as other similar systems used for the same purpose.
The EHR rating is designed to indicate potential hazards of both sheet erosion, and rill or gully erosion from more concentrated flows on roads and skid trails.
"Dead vegetation" serves to both break up raindrop impact and retard surface flow. This prevents the initiation of surface erosion, maintains high infiltration rates to minimize or prevent surface runoff by preventing surface soil sealing, and greatly reduces sediment transport capacity through reduced surface flow volume and velocity. Such surface cover is widely recognized as the most important factor in preventing surface erosion.
During the initial review of the plan, the math on the EHR is checked and obvious inconsistencies questioned. For many counties in California, the Soil Conservation Service has prepared Soil Surveys which often contain ranges of values for several of the factors (detachability, permeability and depth to restrictive layer) for the soil types shown on the maps which are also found in the documents. This allows for an office comparison of the figures calculated by the RPF and likely values for the soil types in the plan area. If a plan is determined to need a PHI, the EHR is generally evaluated in the field.
The rating is used in the plan, as per various FPRs, to guide the spacing of waterbars, limit tractor operations on certain slopes, etc. The rating is not the final word and is not intended to address mass wasting. It is used for general considerations over the bulk of the plan area, on the stable slopes. For example, 14 CCR 914.6 [934.6, 954.6] Waterbreaks states in subsection (c) "The appropriate waterbreak spacing shall be based upon the erosion hazard rating and road or trails gradient." But qualifies that in section f) with "Where waterbreaks cannot effectively disperse surface runoff, including where waterbreaks on roads and skid trail cause surface run-off to be concentrated on downslopes, roads or skid trails, other erosion controls shall be installed as needed to comply with Title 14 CCR 914 [934,954]." 14 CCR 914.2 [934.2, 954.2](i), Tractor Operations [All Districts], states "Where waterbreaks cannot effectively disperse surface runoff, other erosion controls shall be installed as needed."
Unstable areas are addressed in 14 CCR 914.2 [934.2, 954.2] Tractor Operations [All Districts], subsection (d); "Heavy equipment shall not operate on unstable areas. If such areas are unavoidable the RPF shall develop specific measures to minimize the effect of operations on slope instability. These measures shall be explained and justified in the plan and must meet the requirements of 14 CCR 914 [934, 954]."

912.9, 932.9, 952.9 Cumulative Impacts Assessment Checklist [All Districts]
STATE OF CALIFORNIA BOARD OF FORESTRY CUMULATIVE IMPACTS ASSESSMENT
Analysis
Potential Biological Impacts
CWEs associated with forest practices and natural processes affect geomorphic products and processes in watersheds. Changes in geomorphic inputs (wood, water, sediment, removal of shade) alter stream channels in measurable ways. In turn, these changes can have impacts on the biological communities inhabiting them, including but not limited to:
Response: There have been many methods developed to assess cumulative impacts. None of these methods is perfect. A strictly empirical approach cannot succeed because too many land-use activities can combine in too many ways and affect too many potential resources and values. A simple example would be: the effect of sediment from a road on a ridge is much different than if the road were in the stream bottom. The amount of disturbed surface cannot be used as an adequate measure of effect. The checklist format used in THPs relies on the user's expertise, experience and professional judgment, so results are not necessarily reproducible. (Reid, 1991) This is why the rules give CDF, WQ, DFG and DMG the opportunity to review the completed checklist and supporting information. The checklist has significant advantages over other quantitative cumulative analysis methods. It is flexible, requiring assessment of more than one type of impact from more than one type of mechanism. For example, the checklist considers not just the relationship between equipment use and sediment or peak flow changes on streams, like many models, but also stream cover and water temperature relationships, equipment's effects on compaction, effect of harvest on snags and so on. It also allows evaluation of accumulating impacts and recognizes changes in harvesting. Note that logging prior to the FPRs used practices not permitted today and the land is left with the legacy of these practices.
RPFs use a large volume of information in making their determinations. This information includes aerial photographs, soils maps, soil erosion hazard rating, wildlife surveys, and the scientific literature. This has been combined with years of experience and repeated examination of the THP and other areas to assess operational results.
Although the rules require a list of past projects for a period of ten years, the analysis of existing conditions reveals the effects of impacts without regard to the time of creation. Contrary to expressed concerns about production of cumulative impacts by the accumulation of small impacts, which are presumably not addressed by site specific mitigations, watersheds where cumulative impacts are clearly expressed, such as Redwood Creek, have experienced large increases in erosion from clearly identifiable sources caused by pre-rule practices that are no longer permitted.
In many cases, the THP has been submitted by a property owner who has no control over any property other than that where the THP has been filed. In these cases, mitigation of site-specific impacts associated with the THP or the plan area in general is all that can be accomplished. In addition to mitigation of direct THP impacts, potential cumulative impacts are addressed by the use of off-setting mitigation of existing problem sites both on and off the THP area. For large industrial timberland owners there are generally road maintenance plans, agreements with DFG or local habitat restoration groups, habitat conservation plan(s) or other things in place that address reduction of cumulative impacts either directly or indirectly on a watershed or larger basis.
Current in-stream conditions are considered as the basis for determining potential cumulative impacts of proposed operations on beneficial uses.

913.1, 933.1, 953.1 Regeneration Methods Used in Evenaged Management [All Districts; except variances in (a)(4)(A) and (d)(3) Shelterwood Removal Step]
The following types of regeneration methods are designed to replace a harvestable stand with well spaced growing trees of commercial species. Evenaged management systems shall be applied with the limitations described by this rule:
(A) [Coast] The prior evenaged regeneration unit has an approved report of stocking, and the dominant and codominant trees average at least five years of age or average at least five ft. tall and three years of age from the time of establishment on the site, either by the planting or by natural regeneration. If these standards are to be met with trees that were present at the time of the harvest, there shall be an interval of not less than five years following the completion of operations before adjacent evenaged management may occur.
(A) [Northern and Southern] The prior evenaged regeneration unit has an approved report of stocking, and the dominant and codominant trees average at least five feet tall, or at least five years of age from the time of establishment on the site, either by the planting or by natural regeneration. If these standards are to be met with trees that were present at the time of the harvest, there shall be an interval of not less than five years following the completion of operations before adjacent evenaged management may occur.
retained shall be marked by, or under the supervision of, an RPF prior to felling operations. A sample area shall be marked prior to a preharvest inspection. The sample area shall include at least 10% of the harvest area up to a maximum of 20 acres per stand type, and must be representative of the range of conditions present in the area. The marking requirement may be waived by the Director if the trees to be harvested are easily distinguished from the trees to be retained, when explained and justified by the RPF in the plan.

Analysis
Potential biological Impacts
Response: This rule does not stand alone. Unstable areas for the entire plan area are required to be mapped and appropriate measures established for any operations that may be proposed on or near these areas included in the plan. Silvicultural systems are chosen considering the achievement of maximum sustained production of high quality timber products as the major consideration. Field conditions (unstable areas for example) can and do necessitate altering silviculture practices.
Mitigation for increased acreage, the impact from the harvest unit size, and off-site mitigation are considered under the cumulative impacts analysis as well as under this rule section. The plan must be considered as a whole.
Regeneration units may be close to each other both spatially and temporally. Regarding the five year spacing, Chamberlin et al. (1991) states: "Harvested areas contain wetter soils than unlogged areas during periods of evapotranspiration and hence higher groundwater levels and more potential late-summer runoff. The effect lasts 3-5 years until new root systems occupy the soil." (The effect of late-summer runoff could a beneficial factor for fish bearing watercourses during the summer months.)
Any plans with unstable areas where operations such as clear cutting are proposed will get a review and most likely a field evaluation by a DMG Certified Engineering Geologist.

(b) Tractor, or other heavy equipment which is equipped with a blade, shall not operate on skid roads or slopes that are so steep as to require the use of the blade for braking.
(c) Tractor roads shall be limited in number and width to the minimum necessary for removal of logs. When less damage to the resources specified in 14 CCR 914 [934, 954] will result, existing tractor roads shall be used instead of constructing new tractor roads.
(d) Heavy equipment shall not operate on unstable areas. If such areas are unavoidable, the RPF shall develop specific measures to minimize the effect of operations on slope instability. These measures shall be explained and justified in the plan and must meet the requirements of 14 CCR 914 [934, 954].
(e) Slash and debris from timber operations shall not be bunched adjacent to residual trees required for silvicultural or wildlife purposes, or placed in locations where they could be discharged into a Class I or II watercourse, or lake.
(f) [Coast only] Tractor operations shall be subject to the following limitations:
(1) Heavy equipment shall be prohibited where any of the following conditions are present:
(i) Slopes steeper than 65%.
(ii) Slopes steeper than 50% where the erosion hazard rating is high or extreme.
(iii) Slopes over 50% which lead without flattening to sufficiently dissipate water flow and trap sediment before it reaches a watercourse or lake.
(2) On slopes between 50 percent and 65 percent where the erosion hazard rating is moderate, and all slope percentages are for average slope steepness based on sample areas that are 20 acres, or less if proposed by the RPF or required by the Director, heavy equipment shall be limited to:
(i) Existing tractor roads that do not require reconstruction, or
(3) The RPF may propose exceptions to the limitations on tractor operations described above, if the proposed exception will comply with 14CCR 914 [934, 954], and if the THP both clearly explains the proposed exception and justifies why application of the standard rule is either not feasible, or would not comply with 14CCR 914 [934, 954]. The location of tractor roads to be used under such exceptions shall be flagged prior to the pre-harvest inspection or, when a pre-harvest inspection is not required, prior to the start of timber operations.
(1) Heavy equipment shall be prohibited where any of the following conditions are present:
(i) Slopes steeper than 65%.
(ii) Slopes steeper than 50% where the erosion hazard rating is high or extreme.
(iii) Slopes over 50% which lead without flattening to sufficiently dissipate water flow and trap sediment before it reaches a watercourse or lake.
(2) On slopes between 50 percent and 65 percent where the erosion hazard rating is moderate, and all slope percentages are for average slope steepness based on sample areas that are 20 acres, or less if proposed by the RPF or required by the Director, heavy equipment shall be limited to:
(i) Existing tractor roads that do not require reconstruction, or
(ii) New tractor roads that have been flagged by an RPF or supervised designee prior to use.
(3) The RPF may propose exceptions to the limitations on tractor operations described above, if the proposed exception will comply with 14CCR 934 [954], and if the THP both clearly explains the proposed exception and justifies why application of the standard rule is either not feasible, or would not comply with 14CCR 934 [954]. The location of tractor roads to be used under such exceptions shall be flagged prior to the pre-harvest inspection or, when a pre-harvest inspection is not required, prior to the start of timber operations.
(1) Any slopes over 40%.
(2) Slopes over 30% which lead without flattening to a Class I or Class II watercourse or to a lake.
(3)Areas having average slopes over 30%, where the erosion hazard rating is high or extreme. The area sampled for the average shall not exceed 20 acres.
(k) [Southern only] The Director may approve exceptions to (j)(1), (j)(2) and (j)(3) above when damage to soil and water quality caused by the use of heavy equipment will not exceed that caused by other site preparation methods if explained and justified in the THP.
Analysis
Potential Biological Impacts
It is true that off-site mitigation may be mitigated for impacts of heavy equipment on steep slopes, but this is only after all on-site and in-kind mitigations have been applied.
Justifications for individual exceptions are all site specific. Each justification is evaluated by CDF and other members of the review team. Exceptions to the use of heavy equipment on steep slopes have to fit the nature of the slope to be impacted.
Unstable areas are each unique, there are different soil types, different relationships to watercourses and sizes that range from a few square feet to acres. A plan which shows either the crossing of a large unstable area or the crossing of many small ones will usually trigger a field review by the one of the Certified Engineering Geologists with the DMG, as part of the preharvest inspection.
The rule minimizes the use of tractor roads across steep and unstable slopes. The proposal for such roads is thoroughly evaluated by CDF during the preharvest inspection. If reasonable alternatives exist for alternative placement of the road which would avoid the unstable area, these would be recommended and generally made part of the plan by the RPF.
Tractor roads are required to have erosion control structures constructed after operations are completed or prior to the winter operating period. Surface erosion and channelization of runoff from tractor roads is minimized with the inclusion of these structures. Where the tractor roads are already in place from previous harvesting, especially harvesting prior to the advent of the current FPRs, there may be little or no erosion control present prior to the submission of the THPs. A current plan requires the installation of the erosion control structures on these roads regardless of whether they had them prior to the proposed operation.
