The current permit areas is 40 acres and with the expansion of 110 acres the total permit area will be 150 acres. Of the 150 acres 130 acres will be disturbed by mining. The remaining 20 acres serves as buffers and permanent setbacks. Continued development will include implementing water control measures, removal of vegetation including merchantable timber, stripping and stockpiling of soils, excavation via blasting, rock processing (sorting & crushing), staging, and stockpiling and hauling of processed rock. The site will be reclaimed to a forestland post-ming land use. Reclamation will include selective blasting, redistribution of soils, establishment of final drainage, and revegetation. The site is accessed via a private access road off of SR 108. DNR Reclamation Permit No. 70-012642. Site known as the Skookum quarry.

An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. Instructions for Applications: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from you own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write"do not know" or"does not apply". Complete answers to the questions may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help you describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Use of checklist for nonproject proposals: Complete this checklist for nonproject proposals, even though questions may be answered "does not apply'. IN ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). For nonproject actions, the references in the checklist to the words "project", "applicant", and "property or site" should be read as "proposal", "proposer"and"affected geographic area", respectively. A. BACKGROUND 1. Name of proposed project, if applicable. Skookum Quarry Permit Expansion 2. Name of applicant: Port Blakely Tree Farms, L.P. SEPA Environmental Checklist—Skookum Quarry Permit Expansion 70-012642 Pag EVALUATION FOR AGENCY USE ONLY e.Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Post-mining slopes will be established as shown in the reclamation plan. Soils that have been stockpiled during mining will be redistributed over these areas at a minimum depth of 3 feet. f.Could erosion occur as a result of clearing, construction or use? If yes, explain. ❑No ® Yes: Erosion of disturbed soils will be minimized by use of best management practices. g.About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? Buildings on site cover approximately.04%of the area. No new construction is proposed. All buildings will be removed at final reclamation. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: All exposed soil will be mulched and seeded. Overburden will be stored in a stable location, piled in lifts and compacted. Stormwater channels will be armored and/or vegetated. Type 3 stormwater will be monitored after passing through settling/infiltration ponds. 2. AIR a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. Dust-from blasting, crushing, and other operations. Diesel Exhaust-from trucks and equipment. Wood Smoke-from slash pile burning. b.Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. ® No ❑ Yes: c. Proposed measures to reduce or control emissions or other impacts to air, if any: Water will be used to reduce dust impact. Slash pile burning will be infrequent, and will only be done when there is a low probability of affecting population centers. The operation will be in compliance with air pollution control authority requirements. SEPA Environmental Checklist-Skookum Quarry Permit Expansion 70-012642 Page 4 ^.

The proposed expansion area is growing timber and will continue to do so until needed for rock production. (It is divided between Douglas Fir plantations of 8+years and 28+years. (See type map)Current quarry production requires the clearing of 1-2 acres per year. The amount of land cleared per ton of rock extracted would decrease as the height of the face increases. The areas not actively involved in mining or reclamation will be disturbed only by the re-routing of stormwater around operations,or by forestry practices such as:clearcutting,selective thinnings,pesticide or fertilizer applications and slashing. Average rotation age for Douglas Fir plantation,under current Port Blakely forest management policy,is 60 years. Reclaimed areas will be returned to commercial forestry use. There are no adjacent landowners to the proposed expansion area. Present operations are not visible from any public road or residence. Present and future operations will be shielded from view impact by stream buffers if the area is clearcut.The site is accessed from State Route 108 via a two-lane gravel road owned, used and maintained cooperatively by Port Blakely and Simpson Timber Company and their contractors. Public use of the private road system is allowed during quarry business hours. This access is restricted during periods of high fire danger,or when public safety is a concern. The reclamation Plan for Skookum Quarry was updated in 1996 to comply with the 1993 standards. Final reclamation planned for Area A in the 1996 plan will be unchanged. The reclamation contours for Area B will be altered to fit with the reclamation of the proposed expansion area. No phased reclamation has been implemented at this time due to the amount of space required for production and stockpiles. The topography of the expansion area is mixed. There are steep slopes,up to 60%, medium slopes,in the 10%-30%ranges,and nearly flat ridge-top. Drainage from the area is to the Northwest,Southwest,and Southeast. Skookum Creek and some of its tributaries surround the site. At one point the proposed permit boundary is about 100 feet from Skookum Creek(Type 3),however nothing will be disturbed closer than 300 feet. A small seasonal stream(Type 5)that forms the Northwest boundary will be protected by a 100- foot permanent setback. "Permanent"bctundary markers tend to disappear in a commercial forestry setting,so roads and a small seasonal stream will form the permit boundaries for the expansion area. Annual air photos will monitor progress toward the Northeast boundary. Permanent setback boundaries will be flagged when operations approach those areas. Standard Reclamation Plan(Form SM-8A),Page 13 Reclamation Permit/Application No:70-012642 3/27/00 Plan of Operation and Reclamation Phase#1 Consists of"Area A" of the currently permitted area. It has been mined to exhaustion. The pit floor in this area is being used for operations and storage. It will be reclaimed when the floor is no longer needed for these purposes. Reclamation plans are unchanged from the 1996 revision. Phase#2 Consists of"Area B" in the existing permit area and the Southwest portion of the neighboring expansion area. As the need for rock production arises, vegetation will be removed from segments of this area. Merchantable timber will be logged and sold under DNR-FPA permits. Non merchantable trees, brush, and stumps will be piled and burnt under a DNR burn permit. Soils and revegatation will be handled as shown on "soils" page. After removal of vegetation and soil, the rock is drilled and blasted by a licensed contractor. The rock is then sold"as is" or it is sorted and/or crushed. Each product is then placed in its own stockpile. The reclamation bench sequence will begin in phase-2. Because "permanent" markers don't survive long in a commercial forestry setting, reclamation bench locations will be flagged when the excavation nears that location. These benches will be accessed from the road that forms the Northwest boundary and also from the road that runs between Area A and Area B. Both roads will be preserved to support access to forestry operations in and behind the mining permit area. These roads also provide access to reclamation benches and active rock production benches. Bench access roads will be maintained across reclaimed areas. Slope segments in phase-2 will be reclaimed as mining proceeds into phase-3. The reclamation benches will be selectively blasted and formed into continuous slopes of 2:1 or less. These slopes would be complex and curved in plan. Soils addition and revegetation would be handled as shown on the "Soils"page. Approximate minimum size for a manageable forestry unit is 10 acres. Phase#3 Consists of the Northwest portion of the expansion area. It will be developed and reclaimed in the same manner as in phase-2. Test drilling indicates the presence of a "sandstone" cap over the basalt in the Northeastern portion of Phase 3. If this factor proves to be a problem either in terms of slope stability or economic feasibility in mining in this area, then mining will be halted at that point. If it is practical to mine the basalt under the sandstone, then the sandstone will be treated like a lower level overburden (unless there is a market for it). Two major drainages will be developed in this area due to the sinuous shape of this part of the excavation. Maximum depth of mining, 300 feet, will be found in this area. Reclamation of slopes will follow development of the reclamation bench sequence. Access to the upper benches in this area will be from the logging road that runs between Area A and Area B. Again access roads will be maintained across reclaimed portions of slopes. At final reclamation, roads that will be necessary to support future forestry operations will be maintained across the reclaimed slopes. These roads will slow runoff and direct it to protected drainages. Reclamation of Standard Reclamation Plan(Form SM-8A)Page 14 Reclamation Permit/Application No:70-012642 3/28/00 the pit floor will take place at the end of this phase. The pit floor will be ripped and then covered with a minimum of three feet of soil. The final reclamation surface of the pit floor will slope gently to the Southwest. The reclamation surface of the portion of the pit floor adjacent to the reclamation slopes will be flat or slope gently back toward the reclamation slope. This will provide an area that will slow runoff velocities and capture sediment. At final reclamation retention ponds will be located so that they will slow runoff from the reclaimed area before it is released to the forest floor. Total pond capacities will be calculated for a 25 year-24 hour event via the runoff formula shown in the "Stormwater Management" section. Establishment of a vegetative cover and continued use of best management practices should allow reduction of pond size with time. Standard Reclamation Plan(Form SM-8A)Page 15 Reclamation PermidApplication No:70-012642 3/28/00 SOILS The quarry area is covered with soils of the Tebo series. These are reddish-brown, well - drained upland soils. The soils have developed in place from weathered basaltic or andesitic rock. In addition, glacial deposits have influenced the upper part of the profile. The rainfall is 60 to 100 inches per year. The native vegetation is a dense and luxuriant forest, mainly Douglas Fir. Tebo soils are found mainly in the Southern part of Mason County. A general profile of Tebo soils is as follows: 1"-2" Mat of forest litter. 3"-6" Surface soil of reddish-brown granular and friable loam. Many small, roots; numerous small, reddish shot; and occasional angular fragments of basalt, gravel and stones in the surface soil. 6"-10" Friable and granular material that is slightltly lighter colored and slightly finer in texture than the layer above. 10"-18" Subsoil is firm, yellowish-red, strong blocky clay loam containing a few shot. 18"-48" Subsoil is strong brown, firm clay loam mixed with irregular basaltic stones and disintegrating basalt. 48"+ The subsoil grades to a substratum of highly weathered, firm massive stony clay loam that is stained with yellow and purple. The substratum grades to bedrock at depths ranging from 3' to 6'. Test drilling has identified pockets of overburden up to 35' thick, with an overall average depth of 12'. Test drilling also shows that the basalt in the Northeast portion of the expansion area is overlain by varying depths of"sandstone". - Soil Management and Storage As a general rule, soil disturbances will be kept to a minimum, and soils won't be disturbed when overly wet or overly dry. Portions of the permit or expansion areas that are not being used for rock production will remain in timber production. When it becomes necessary to clear more ground, the nonmerchantable timber, brush, stumps, and etc. will be removed, piled and burnt. The merchantable timber will be logged and sold. A location will be picked for soil storage that is stable and positioned so that the material is easily available for reclamation (No storage on slopes greater than 30%, or in areas that are recognized as being potentially unstable, storage on slopes of 10%-30% will be keyed into the slope). Then the vegetation will be removed from the storage area as mentioned above. Next the topsoil will be separated, if possible, and piled with a minimum of compaction. Maximum pile height will be 25 feet. Maximum side slopes on the pile sides will be 2:1. Then the overburden will be removed, piled in lifts, and compacted.

FOR DEPARTMENT USE ONLY: Date accepted Accepted by Reclamation Permit No. Pile height, and side slopes maximums will be the same as topsoil piles. Surface drainage will be routed away from soil stockpiles. Catch basins and brush berms will be constructed downhill from the soil storage sites to catch sediment. If the stability of the toes of the soil piles is in question, a pad of basalt cobbles will be built to stabilize the area that the toe rests on after the site has been prepped. (See map 5) If soil storage areas disrupt natural drainage, then subsurface drains (blanket, toe, french, etc.)(See map 5) will be installed to reduce the potential of water ponding behind the fill and subsequent failure of the fill. The pit floor will be ripped to increase permeability, then topped with minimum of three feet of soil. Soils on reclaimed slopes will be ripped parallel to contours if there is a need to increase infiltration rates and reduce sheet erosion. One area(see map 6) has been identified with overburden depths of 35+feet. Unless economic conditions change, this material will remain in place and result in a mound on the pit floor. Side slopes on this mound will be 2:1 or less. Soil Budget Test drilling (see map 6) of expansion area shows overburden depths in a range from 0 feet to 35+ feet. An average of 12 feet is being used for soil budget calculations. Of the 110 acres in Phases 2 and 3, approximately 90 acres will be disturbed. The following formula yields soil volumes. SOIL DEPTH * #OF ACRES*43,560 SQ. FT. PER ACRE = CUBIC YARDS SOIL 27 Plugging in the values for soil depths and a 90 acre area yields the following: 1,742,400 cubic yards material available for reclamation -436,600 cubic yards needed for a minimum covering depth of 3' 1,306,800 cubic yards excess material Excess material will be used to thicken the minimum soil depth. Salvaged topsoil will be spread evenly over the site. If there is a shortage it will be arranged in rows or islands. Mulching and Seeding Disturbed soils will be mulched with hay as soon as possible after disturbance. Then they will be seeded with a grass/clover mixture (approximately 60-70 pounds of erosion control mix grass seed+ 5 pounds of white clover seed per acre on the slopes,40-50 pounds of erosion control grass seed mix +5pounds of white clover seed per acre on the pit floor). This seeding will be timed so that there is a high probability of successful germination. (E.g. spring or fall) Ditches with a low potential for erosion will be seeded with the grass/clover mixture. Ditches with higher erosion potential will be seeded and armored with gabion or larger rock. Ditches with very high erosion potential will be lined with fabric and filled with gabion rock. Standard Reclamation Plan(SM-8A)Page 17 Reclamation Permit/Application No:70-012642 3/27/00 Reclamation Soils and Revegetation After complex and curved slopes are established on a segment that is ready for reclamation, a minimum of 3 feet of soil will be spread over the area. Ideally this would happen when one area was being cleared and another was ready to reclaim (concurrent reclamation). However, at this time, Skookum Quarry has no areas ready to reclaim. The soils would be spread with a minimum of compaction. They will be placed with tracked equipment that will leave growser marks perpendicular to the slope. Soils will be mulched and seeded as mentioned above. Then during the following September through March time period, Douglas Fir seedlings will be planted at a rate of approximately 500 per acre. Any soil storage area that has a probability of remaining in place for 5+years will also be planted with seedlings. (This will aid in soil development, reduce runoff, and provide a"laboratory" in which to learn about seedling survival under reclamation conditions.) Western Red Cedar will be spot planted in areas where soil conditions are to wet for Douglas Fir survival. Port Blakely's long history with seedling regeneration and timberland management provide a rich resource to help ensure a successful conversion of reclaimed minipg land back to commercial forest. Standard Reclamation Plan(Form SM-8A)Page 18 Reclamation Permit/Application No:70-012642 3/27/00 } Geology of the Skookum Quarry Area The rock being mined at Skookum Quarry is Lower? Crescent basalt. This basalt is fine grained and shows columnar jointing indicating subaerial deposition. Column diameters are approximately 18 inches. Column orientation in the front of Area B shows a rosette pattern. The most recent blasting event in that area exposed rock of a more massive nature. There are minor deposits of calcite? Both as vein and vug fill. The golden glint of pyrite also sparkles on a few surfaces. Test drilling (see map 6) indicates that the basalt on the eastern side is overlain by varying depths of"sandstone". Test drilling also shows isolated dirt seams but nothing widespread enough to raise concerns about a slip plain. The Mason County soils book shows no landslide deposits in or near the permit area. Likewise the Mason County Comprehensive Plan does not identify this as a critical area for landslide hazards. A Prevashon drift influences the upper soil horizon. It has been observed as a thin layer where rounded stones intermix with angular basalt.

One or a combination of vegetation,armoring,or fabric will protect ditches. Disturbed soils will be mulched and seeded. Overburden will be stored in a stable location, piled in lifts and compacted. Soil disturbances will timed to take place during dry periods.Topsoil will be separated where possible then mulched and seeded. In "Area A", which is the stockpile and processing portion of the original permit area, the stormwater management plan will remain unchanged from what is shown in the 1996 revision. The proposed expansion will affect"Area A" only by reducing the size of the watershed for this area. Features that will be maintained in "Area A" are a permanent berm and setback on the South side. A series of settling/infiltration ponds will also be-maintained. "Area B" is the excavation portion of the existing permit area(All future excavation in the proposed expansion area will be contiguous with "Area B"). A French drain has been constructed to capture surface drainage from the existing excavation and directs it to ground or a series of settling/ infiltration ponds. Any release from these ponds spreads over relatively flat terrain that is heavily vegetated with Douglas fir plantation and grass. As the excavation enlarges into the expansion area the pond capacities will be increased to match the size and condition of the watershed. In Table-1 I have predicted potential runoff in the "Area B" watershed for four different watershed conditions in a 25 year 24 hour event. The worst case scenario for"Area B"is to have the entire 110 acres disturbed with a surface that is largely impervious. This example shows that we would need a retention capacity of 93,125 cubic yards or a total pond capacity of 5.8 acres if the ponds were 10 feet deep. Total pond capacity at final reclamation after the watershed has been returned to the forested state would be 36,160cubic yards or 2.2 acres with a 10-foot depth. Recognizing that the watershed will evolve as operations progress and as such will be a combination of the four factors shown in Table 1. We will use runoff predictions per acre of each condition to predict retention pond capacities during operations/concurrent reclamation/final reclamation/etc. We will also use these numbers to predict the effects of silvicultural practices in the area. Pond capacities will be reduced if we find that implementation of Best Management Practices reduces the need for total retention capacity. The actual maximum disturbance will be approximately 90 acres. In Table-2 I show calculations for predicting peak discharges in the same watershed under four different conditions. Again this is a worst case scenario. Similar calculations will be made at final reclamation. The final size of the disturbance and the condition of the watershed should give us a handle on proper sizing of the"stream"channels that will flow across the pit floor. There is a small intermittent stream that forms the Northwest boundary of the expansion area. The streambed is a gentle grassy swale that has been planted with Douglas fir and Sitka spruce. There is no channel development until it nears the crossing of the road that forms the Western boundary. This stream will be protected by a 100-foot permanent setback. In general the pit floor in "Area B" will slope gently away from the highwall. However as the development of this pit floor approaches.the point where"Area B" will be mined for reclamation slope then the pit floor will be sloped gently toward the highwall. This will provide an area where water velocities can be reduced and larger sediment deposited. Also the two rows of drill holes closest to the highwall of the first reclamation bench will be subdrilled ten feet below pit floor level to act as a French drain. At final reclamation two major drainages will flow from the reclaimed slopes. These and any minor drainages that develop will be directed into settling/infiltration ponds at the base of the slopes. From these ponds any water that didn't infiltrate will flow across the pit floor to a series of settling/infiltration ponds near the permanent berm. Ponds that are blasted from bedrock will require little or no outlet protection. However those excavated from erodable materials will have outlet spillways that protect against pond failure. These spillways will be protected against erosion. Protection features will include armoring,fabric,and culverts with flumes.
