2011 Annual Work Plan for Master Agreement for Timber Operations and

Road Management Waste Discharge Requirements

Pursuant to the Master Agreement for Timber Operations (MATO) (1600-2010-0114-R1) issued by the Department of Fish and Game (DFG) on May 18, 2010 and Road Management Waste Discharge Requirements (RMDR) (R1-2010-0044) issued by the North Coast Water Quality Control Board (NCWQCB) issued on June 10, 2010 an Annual Work Plan (AWP) is required to be submitted by Green Diamond Resource Co (GDRCo) describing all planned activities for 2011 for enrollment under these permits. The activities proposed under this AWP for sites not related to Timber Harvest Plans include watercourse crossing upgrading in the Hunter Creek, Terwer Creek, Mynot Creek, and Mad River drainages. These projects are being initiated per the Routine Road Maintenance standards under AHCP 6.2.3.9. The detailed site descriptions for all watercourse crossing sites can be found under the Road Work Order on pages 5 through 18 (Mad River) and on pages 87 through 171 (Klamath area). There is a significant amount of upgrading and decommissioning in this Annual Work Plan related to THPs. The sites included are within approved THPs, only. It is anticipated that additional sites will be amended to this Annual Work Plan as “New Site Revisions” as THPs are approved through the season. The detailed descriptions for the operating area south of Bald Hills Road can be found on pages 19 through 86 and the operating area north of Bald Hills Road can be found on pages 172 through 200. Water drafting activities are located in proximity to harvesting activities scheduled for 2011 on the property, specifically Little River, Maple Creek, North Fork Mad River, Ah-Pah Creek, Surpur Creek, Wilson Creek, Dominie Creek, and Rowdy Creek drainages. The notifications for these sites are the same notifications provided in the 2010 Annual Work Plan. Any site not previously included in a valid 1600-permit or the previous Annual Work Plan will be amended to this plan as “New Site Revisions”. The detailed descriptions for all water drafting sites can be found on pages 201 through 209. A monthly water drafting report will be submitted to DFG no later than 30 days after water drafting activities are reviewed and commence on the sites disclosed under this Plan. There are no in-stream restoration projects proposed. Maps and culvert calculations, where applicable, are located prior to the Road Work Orders for each distinct project area or THP. For sites associated with THPs the individual THP maps are included for each referenced plan. The review requirements for wildlife, plants, archaeology and non-fish aquatic vertebrates (refer to Section B and Attachments 1 through 3 of the MATO) are on-going.

v. 2.0 (5/2/2011)

To date, wildlife issues have been identified, specifically related to the northern spotted owl, willow fly catcher and marbled murrelet for non-THP projects. No operations will be conducted prior to official notification from GDRCo wildlife staff that seasonal restrictions can be lifted. Please refer to the Road Work Orders for specific species-related restrictions. Botantical surveys are on-going for non-THP projects. There have been no sensitive plant species identified to date. If specific operational restrictions are required for specific sites, then a Site Revision will be sent to DFG prior to the start of operations and CNDDB records submitted for qualifying plant species. No operations will be conducted prior to official notification from the GDRCo botanical staff that all surveys are complete and any mitigation measures are revised for any affected site. Requests for archaeological information related to Non-THP projects were sent to tribal organizations. To date GDRCo has not received any information indicating that Non-THP related projects would potentially affect any archaeological resources. Initial non-fish aquatic vertebrate surveys were completed on all sites included in this AWP. Staff herpetologists are currently reviewing the identified sites. Any mitigation measures performed at identified sites and results will be discussed in the 2011 Annual Work Report to be submitted on March 31, 2011. All sites included in this AWP for THP-related notifications shall follow all wildlife, botanical and archaeological restrictions set forth in the respective THPs. An Annual Report has been submitted to both agencies on March 31, 2011 summarizing the work completed in 2010. As a result of field review of this AWP revisions have been made to the first version submitted on March 1, 2011. A summary of these revisions are included below:

1. Site H400-03: DFG recommended that the proposed culvert size be increased to 48” diameter. The recommendation is included in the revised treatment for this site.

2. Site R32-01: DFG and NCWQCB recommended the option of cleaning the culvert with mitigation measures included to prevent significant sediment delivery from flushing of culvert be included in the proposed treatment. Additionally, NCWQCB recommended the site description be revised to reflect the current culvert diameter of 24”. These recommendations are included in the revised treatment for this site.

3. Site R32-03: DFG recommended that the site description be revised to state the current culvert is 60” in diameter. The recommendation is included in the site description for this site.

4. Site R32-04: DFG recommended that the proposed culvert size be increased to 36” diameter and to install a single-post trash rack. The recommendation is included in the revised treatment for this site.

5. Site T250-01: DFG recommended the outlet of the new culvert be armored. NCWQCB recommended that a Professional Geologist be on-site during installation of new crossing to direct the placement of the outlet. These recommendations are included in the revised treatment for this site.

v. 2.0 (5/2/2011)

6. Site T250-02: NCWQCB recommended the adjacent (left) in-board ditchline be rock armored if disturbed during crossing installation. The recommendation is included in the revised treatment for this site.

7. Site U10-26: DFG and NCWQCB recommended that a new site be included in the AWP (U-10-26.1) to install a culvert at the diverted watercourse located adjacent (left) to Site U10-26. This site is included in the New Site Revision submitted on May 2, 2011.

8. Site U430-01: DFG recommended that the proposed new culvert size be increased to 24” diameter. The recommendation is included in the revised treatment for this site.

9. Site U10-21: DFG recommended that excavation of the sediment wedge be limited to the area below the confluence of the main watercourse and a secondary watercourse which enters to the left. Additionally, the headcut will be armored, and extended to the inlet. Any trees removed during sediment wedge excavation will be placed stream-side outside the area of armor. The recommendation is included in the revised treatment for this site.

10. Non-THP Sites (all): All culvert sizes were recalculated for all Non-THP sites as a result of concerns related to passage of bedload and woody debris. Many proposed sizes were increased to account for this concern. No proposed sizes were decreased as a result of the calculations. Please refer to the culvert calculation reports included for each project which are located preceding the Road Work Orders.

CURRENT CONDITION : A Class II watercourse with a 12" CMP has a sediment wedge and an inlet that is completely buried by accumulated sediment. The watercourse has overtopped the road and gullied through the outboard fill, and there has been some past failure of the over steepened fill face as a result. The culvert is short and set high in the fill. There is some water emerging from the base of the fill, where old Humboldt logs emerge.

TREATMENT : Excavate from the flagged bottom to the flagged top, including the sediment wedge at the top and any buried logs. Install a 36" culvert that meets the standards of the FPRs and this THP on grade with drainage disconnect structures on both approaches to hydrologically disconnect the watercourse from the road .

CURRENT CONDITION : A Class II watercourse with a 30" CMP is mostly bypassed through the fill by flow around old Humboldt logs buried below the culvert. The culvert is set high in the fill and shotguns onto the toe of the fillslope when there is enough discharge to actually make it through the culvert. The watercourse makes a sharp angled turn at the inlet.

TREATMENT : Excavate from the flagged bottom to the flagged top, including any sediment accumulated at the top and any buried logs. Install a 30" culvert that meets the standards of the FPRs and this THP on the natural channel grade; OR excavate and remove the existing culvert and install a single 60" culvert for Points 2 & 3 that meets the standards of the FPRs and this THP on the natural channel grade

CURRENT CONDITION : A crossing on a Class III watercourse lacks a drainage structure. Some water runs down the road to an adjacent area of instability approximately 75’ down the road to the left, and some overtops the road and erodes the outboard fill.

TREATMENT : Excavate from flagged bottom to flagged top and install a 24" culvert to that meets the standards of the FPRs and this THP on grade with a critical dip over the left hinge-line of the excavation and armor at the transition point near the inlet to minimize headcutting above. Or: Install a rocked ford that is armored past the transition in grade on the outboard edge of the road. Install a drainage disconnect structure on the right approach to hydrologically disconnect the watercourse from the road.

CURRENT CONDITION : A collapsing Humboldt crossing sits on a Class II watercourse with slumping fill in the middle of the road and a past failure of the outboard fill to the left. Some water goes subsurface at a sediment and debris plug up the channel and emerges below a log at the base of fill. At high flows water appears to overtop and runs uncontrolled over the surface of the road delivering sediment to the watercourse below. It appears that water used to divert to the left but now that the crossing has lowered, diversion is less likely.

TREATMENT : Excavate from the flagged bottom to the flagged top, including the sediment plug at the top and any buried logs. Install a 30" culvert that meets the standards of the FPRs and this THP on grade with a critical dip over the left hinge-line of the excavation. Install a drainage disconnect structure on the right approach to hydrologically disconnect the watercourse from the road.

There are suspected Humboldt logs protruding from the base of the fill. Sediment has built up above the inlet due to the shallow culvert gradient.

TREATMENT : Excavate from the flagged bottom to the flagged top, including the sediment built up at the top and any buried logs. Install a 24" culvert that meets the standards of the FPRs and this THP on grade with a critical dip over the left hinge-line of the excavation.

CURRENT CONDITION : A Class II watercourse diverts down the inboard ditch approximately 75 feet to a ditch relief culvert that is a 24" CMP with a half round downspout that effectively conveys water past the end of the fill, but then dumps it on the hillslope where it gullies back to the watercourse below. There is evidence of overtopping at the crossing that has led to a past failure of the outboard fill with delivery to the watercourse

TREATMENT : Excavate from the flagged bottom to the flagged top. Install a 24" culvert that meets the standards of the FPRs and this THP on grade along the natural alignment of the watercourse with a critical dip over the left hinge-line of the excavation. The existing culvert may be left in place as a ditch relief culvert. Install a drainage disconnect structure on the right approach to hydrologically disconnect the watercourse from the road.

CURRENT CONDITION : A Class II watercourse has a 24" CMP with an extensive sediment wedge accumulated upstream of an inlet that is partially crushed. The culvert appears to be separated at an interior joint and water flows out underneath the culvert, bypassing the half round downspout. There are voids forming in the fill where the culvert has been bypassed and there is additional water emerging from the bottom of the fill, indicating that there may be old Humboldt logs buried below.

TREATMENT : Excavate from the flagged bottom to the flagged top, including the sediment wedge at the top and any buried logs. Install a 42" culvert that meets the standards of the FPRs and this THP on the natural watercourse grade. Install a drainage disconnect structure on the right approach to hydrologically disconnect the watercourse from the road.

CURRENT CONDITION : A Class II watercourse with an 18" CMP has a sediment wedge and an inlet that is completely buried by accumulated sediment. The watercourse is diverted approximately 120’ to the right via the inboard ditch before it gullies across the road and outboard fill. The watercourse has also overtopped the road at the crossing site and there has been some past failure of the over steepened fill face as a result. The culvert is separated and is visible through a collapse hole in the center of the road. It is also short, set high in the fill and has a long half round downspout that is filled with debris from an old failure adjacent to the left. There is water emerging from the bottom of the fill, indicating that there may be old Humboldt logs buried below. TREATMENT : Excavate from the flagged bottom to the flagged top, including the sediment wedge at the top and any buried logs. Install a 30" culvert that meets the standards of the FPRs and this THP on grade with a critical dip over the right hinge-line of the excavation. Install a drainage disconnect structure on the left approach to hydrologically disconnect the watercourse from the road.

CURRENT CONDITION : A fill crossing on a Class II watercourse has overtopped. Water flows uncontrolled over the surface of the road and gullies through the outboard fill to the channel below.

TREATMENT : If water is flowing at the time of operations install a spittler or other temporary crossing of sufficient size to conduct flows present to allow equipment and truck passage. Excavate from the flagged bottom to the flagged top, including any sediment accumulated at the top and any buried logs. Abandon the crossing to the standards of the FPRs and this THP. Install a drainage disconnect structure on the right approach to hydrologically disconnect the watercourse from the road.

CURRENT CONDITION : A collapsing Humboldt crossing sits on a Class II watercourse with sinkholes and slumping fill in the road and outboard fill. Some water goes subsurface at a sediment wedge and emerges below a log at the base of fill. There is direct delivery of sediment to the watercourse below. This site is currently impassable to vehicles.

TREATMENT : If water is flowing at the time of operations install a spittler or other temporary crossing of sufficient size to conduct flows present to allow equipment and truck passage. Excavate from the flagged bottom to the flagged top and abandon the crossing to the standards of the FPRs and this THP. Install drainage disconnect structures on both approaches to hydrologically disconnect the watercourse from the road.

CURRENT CONDITION : Site is a fill crossing on a Class III watercourse. Two channels merge above the top flagging at a bedrock outcrop. The fillslope has failed, exposing large rock and possible Humboldt logs. A swale 120’ to right (Site 10) contributes road surface flow to the outboard road edge of this site.

TREATMENT : Excavate from top to bottom flagging, removing all Humboldt logs and woody debris. Install a 30" CMP on grade to THP and FPR standards. Install a hydrologic disconnect on the right approach and apply energy dissipating rock below the outlet. Apply rock armor where necessary to stabilize the stream banks and fill slope. Note: The excavation of this site will tie in together with the adjacent crossing (Site 8). The installation of culverts at both sites will require their outlets aligned with the single channel below.

CURRENT CONDITION : Site is a fill crossing on a Class III watercourse. Heavy tractor activity in the past has fractured the watercourse into multiple channels upslope. The channel at right is well defined upslope and cuts askew across the road. A cutbank seep 150’ to the right approach runs down the road surface, combining with the right channel in a gully down the fillslope. The center channel is swale-like and not well defined upslope. Surface runoff from two skid trails 100’ to the left combine with the center channel, forming large sink holes in the road prism. The combined flow enters a second fillslope gully on the left hinge line.

TREATMENT : Excavate the entire crossing between both top flags down to the bottom flagging, removing all large woody debris. Install a 24” CMP on grade to THP and FPR standards. Apply rip-rap at head cut and at culvert outlet if needed for grade control. Install a hydrologic disconnect on the left approach as feasible with new spur road. Install outsloped rocked dip or ditch at the right approach within 100-150 feet to disconnect runoff from seep and entrenched skid trail.

CURRENT CONDITION : Class II perennial watercourse with a 24” plastic pipe set high in the fill. The outlet is short in the fill with a half-round shotgun downspout, perched 15’ high on a Humboldt log. An erosional void under the downspout is beginning to undermine the culvert. A swale 140’ to the right contributes ditchline flow to the watercourse.

TREATMENT : Remove plastic downspout from outlet of culvert. Remove imbedded logs and woody chunks in fill at the culvert outlet. Excavate the existing fill slope below the pipe to a stable grade. Rebuild the fill slope using heavy rock from the culvert outlet to the bottom of the fill slope. Position rock armoring to act as dissipater for outlet. Place additional rock in plunge pool at bottom of fill slope. Install an 18” DRC with a full-round downspout at the swale 140’ up the right approach to function as a hydrologic disconnect to Class II. watercourse.

CURRENT CONDITION : Class III watercourse crossing has a 24" CMP installed. The inlet has a wooden trash rack with sediment backed up to the top of the inlet. There is a 3' drop to the inlet from the trash rack. Boards from trash rack are beginning to weaken and could plug the pipe. The inlet has advanced rust. The outlet is set near the base of fill. Sediment at trash rack qualifies as debris within one culvert diameter of inlet that could cause blockage. A rust line that is >50% at the outlet indicates that the culvert is undersized. The channel is head-cutting at low gradient just below the outlet.

TREATMENT : Excavate from top to bottom flags and install 36" culvert to AHCP standards.

CURRENT CONDITION : 24" CMP on Class II stream with past debris torrent. Sediment and woody debris have deposited into channel and buried the culvert inlet, creating a 36'W x 20'L pond behind fill crossing. Sediment plug in culvert 10' from outlet.

TREATMENT : Either clean inlet and flush culvert ensuring appropriate measures are in place to minimize downstream sediment delivery (i.e. silt fence, catch basin, etc) --OR-- Excavate from TOP to BOT removing large woody debris and sediment wedge. Armor headcut and left stream bank below TOP flag.Install new 24" CMP to AHCP standards. Install 18" DRC 75ft to left.

CURRENT CONDITION : Steep (26%) class II flows over bedrock and has deposited a thick sediment wedge (54'x81') that buries a 60" CMP completely. Pipe is disconnected about 20' from the outlet causing fill saturation, erosional voids, and gullying of the fillslope. Low gradient half round downspout with sediment accumulation in pipe. Outfall is suspended ~8' over natural channel.

TREATMENT : Excavate from TOP to BOT, including slide debris along right bank where the natural watercourse and diverted slide flow intersect near BOT. Lay slope back and amour right bank (toe of slide). Remove sediment wedge at inlet. Replace pipe with 72", 120' long culvert and install on grade (-26%). Install critical dip at road/stream xing and energy dissipater rock at outlet. Excavate slide debris to toe of the slide (confluence w/ stream). Rebuild road prism including IBD between stream and slide. Armor road fill slope and cutbank for stabilization. Install 18" DRC 75ft to left, re cut ditchline for 150ft at cutbank failures.

CURRENT CONDITION : A Class II spring emerges from the cutbank and is drained by an 18” CMP. Minor cut-bank failures associated with the spring have caused debris to collect at the inlet. The failing cut bank has undermined the root system of an approximately 24" Douglas-fir tree just above this road point. The tree is leaning and has most of its limb weight towards the road creating a potential hazard.

TREATMENT : Remove the hazardous Douglas-fir tree. Excavate the debris accumulated at the culvert inlet. Buttress the cutbank with rip-rap to protect the culvert and minimize the potential for future cutbank failures.

CURRENT CONDITION : A seasonal spring overwhelmed the inside ditch during a large rain event saturating the fill slope of an approximately 125' section of road, causing it to slip vertically 6 to 8 inches. The movement of the road surface caused a 24" CMP on a Class II watercourse to shear in half. Approximately 1 yd3 of material from the road surface collapsed into the pipe partially plugging the outlet.

TREATMENT : Replace the sheared CMP with a 24” culvert installed to AHCP standards on grade with a critical dip. Install an additional 24” culvert to conduct the seasonal spring across the road. The remainder of this road segment shall be reshaped with a grader to facilitate log hauling.

CURRENT CONDITION : A Class II watercourse with a 12" CMP has a sediment wedge and a very rusty inlet that is almost completely blocked by built up sediment. There has been some past failure of the over steepened fill face. The culvert is short, set high in the fill and has eroded fill below the outfall. Most of the flow goes subsurface below the shotgun outlet and reemerges at the base of fill.

TREATMENT : Excavate from flagged bottom to flagged top, including the sediment wedge at the top and any buried logs. Install a 24" culvert to AHCP standards on grade with a critical dip.

CURRENT CONDITION : A 12" rusty CMP on a Class II watercourse is misaligned causing a gully where it discharges on to fill. The outlet is nearly buried by fill face failures and there are multiple holes in the outboard fill face. Stream flow goes subsurface before the culvert inlet at the sediment wedge and emerges at the base of the outboard fill. The existing culvert may be separated at an interior joint.

CURRENT CONDITION : A Humboldt crossing on a Class II watercourse has a sediment wedge built up above the road. The channel above is disrupted by a legacy skid road approximately 75' above the top and there are legacy tractor impacts to the channel itself. There is some erosion of the fill slope where water appears to have overtopped the road at high flows, but most water flows subsurface through the site.

TREATMENT : Excavate from flagged bottom to flagged top, including the sediment wedge at the top and any buried logs. Install a 30" culvert to AHCP standards on grade with a critical dip. The transition point on the sediment wedge may require buttressing with riprap to minimize future headcutting.

CURRENT CONDITION : A Class II watercourse crossing has an extensive sediment wedge behind it that has buried the original culverts. A 36” diversion culvert was recently installed to channel water to an adjacent gully, but a sinkhole has since opened up at the inlet of an old culvert along the original alignment causing the watercourse to incise through the sediment wedge leaving the diversion high and dry. Water currently makes its way through cavities in the fill and through one of 4 old rusted out CMPs protruding from the fill along the original alignment set at various depths.

TREATMENT : Excavate from the flagged bottom to the flagged top on the sediment wedge and install a 42" culvert to AHCP standards. The transition point on the sediment wedge may require buttressing with riprap to minimize future headcutting. The diversion culvert can be left in place as overflow protection, or install a critical dip.

CURRENT CONDITION : A Class II watercourse crossing is drained by Humboldt logs. There is a sediment wedge built up above the road, and legacy impacts associated with past tractor operations at this site. There is a small gully in the fill slope where water may have overtopped the road in the past. There is a high potential for diversion and some past diversion from this site appears to have contributed to the fill failure associated with the right approach to Road Point 19. This site is downstream of Road Point 15 and may receive somewhat higher flows after the road work is completed at that site.

TREATMENT : Treat prior to the Winter Period (Oct.16), unless "Unseasonably Dry Fall" conditions are in effect (Oct.16 - Nov.15) of the year Road Point 15 is upgraded. Excavate from flagged bottom to flagged top, including the sediment wedge at the top and any buried logs. Install a 24" culvert to AHCP standards on grade with a critical dip.

CURRENT CONDITION : A Class II watercourse crossing with a 12" CMP has a sediment wedge above the inlet. The culvert inlet has collapsed and the fill adjacent the culvert is eroded undercutting the road to the approximate centerline. Humboldt logs are visible protruding from the base of fill. There is an old shallow fill failure along right margin of the outboard fill and the toe slope is undercut by a gully channel from the shotgun culvert outfall. The fill failure appears to be the result of a drainage diversion from another site up the road that was conveyed to this site by the inboard ditch. Water goes subsurface at the sediment wedge approx 20' from the culvert inlet and reemerges near the bottom.

TREATMENT : Excavate from the flagged bottom to the flagged top, and install a 30" culvert to AHCP standards, with a critical dip. Install an 18” ditch relief culvert approximately 80’ up-road to disconnect the inboard ditch from the watercourse.

CURRENT CONDITION : A 12” culvert fed by cutbank seeps and the Class II unit boundary watercourse is rusted out and eroding the outboard edge of the road. The road is undercut and may be unsafe to haul on prior to road work. There is a Class II watercourse immediately below with direct delivery to a Class I watercourse 80 feet downstream. The existing culvert is accumulating sediment at the inlet and is approximately 25% plugged.

TREATMENT : Rock line the inboard ditch for approximately 75' from the boundary watercourse to the culvert and replace the existing 12” ditch relief culvert with a 24” culvert placed on a steeper gradient to reduce plug potential. Install a critical dip and rock armor at the culvert outlet.

CURRENT CONDITION : A Class II watercourse crossing has an 18" CMP placed off the natural alignment and grade and a sediment wedge above the inlet. The inboard ditch delivers directly to the culvert inlet. The culvert is rusted through for more than 25% of its length and approximately 25% of flow bypasses the culvert underneath. The road is severely undercut and the outboard fill face is badly eroded where the outlet used to shotgun onto the fill.

TREATMENT : Excavate from flagged bottom to flagged top, including the sediment wedge at the top and any buried logs. Install a 36" culvert with an inlet cut at an angle to AHCP standards, with a critical dip. Install an 18” ditch relief culvert approximately 75’ up-road to disconnect the inboard ditch from the watercourse and inslope or crown the road for at least 50’ leading down to the ditch relief culvert.

CURRENT CONDITION : There is approximately 70' of cracked fill along the outboard edge of the road. The cracks are approximately 6"-8" wide and extend up to 6’ from the outboard edge of the road. This site is within the WLPZ, approximately 60' from the toe of fill to the Class II watercourse below. The estimated approximate dimensions are w:70' x l:10' x d: 3'

TREATMENT : Excavate the unstable fill material between the flagged margins. The road’s running surface can be moved toward the cutbank. The road is wide and the cutbank probably does not need excavation.
