O. BOX 578 Shelton, WA 98584 SUBJECT: HAMA HAMA COMPANY FILL PERMIT Dear Sir: This letter is being written as a result of our on-site meeting yesterday. We have prepared the needed documentation necessary to begin the process of permitting the fill site referenced above. Enclosed herewith please find the following: • SEPA Checklist • Site Map • Conceptional Fill Plan w/Cross Sections Written description of Filling and Grading Plan W/Erosion and Sediment Control Requirements We fully understand that fees are required for the SEPA Checklist as well as the Fill Permit application still to be submitted. We ask that you proceed with the initial review as soon as possible. If you will provide the forms for the Fill Permit Application and the cost for that application as well as the SEPA Checklist fee we will forward a check to Mason County for those fees. We believe that yesterdays meeting of the concerned parties was productive and also hope that it served to reach a common understanding of the fill permit requirements. We request that consideration be given towards allowing us to proceed with a fill of up to 20,000 cubic yards as the permit process proceeds. We also believe that the public need and necessity of reopening SR-101 as soon as possible provides ample justification for the granting of our emergency request. If Mason County concurs the Washington State Department of Transportation would like to begin almost immediately to haul fill to the site so that the Ayock Slide Site can be reopened to at least one way traffic while the larger project is bid. itW,Uo ® We are a member of the A.G.C. of Washington AN EQUAL OPPORTUNITY EMPLOYER I S CONTRACTOR REGISTRATION NO.

Inc. P. O. Box 1707 819 West State St. Aberdeen, WA 98520 Quigg Bros. Inc is proposing to construct a landslide debris fill on property owned by the Hama Hama Company. The quantity of material to be placed is currently unknown, but the site capacity is estimated to be more than 250,000 Cubic Yards. The fill material consists of landslide soils to be removed from the Ayock(M.P. 322) and Lilliwaup (M.P. 326) Landslides on SR-101 south of the mouth of the Hama Hama River. No stumps or wood waste will be placed into the fill constructed under this proposed project. The site of the proposed landfill is in a forested valley. No storm water or other drainage from the site enters the surface waters of the State as the fill site terminates at a natural pothole at its north eastern boundary. The underlying soils in the area are sand and gravel overlain by a thin layer of topsoil. The fill site currently infiltrates storm water into the ground when rainfall intensities are such that onsite infiltration on the surrounding hillsides cannot accept all of the rainfall.. The pothole shows evidence that the water level sometimes reaches 5 or more feet in depth,however as the soils are free draining and the duration of this inundation is not sufficient to sustain wetland type plants. The area was dry during each of two recent visits. The intent of the proponent and the property owner is that storm water ponds will be established on each end of the fill. This will allow storm water to infiltrate into the ground water which duplicates the existing systems function.. The proposed fill will occur in stages beginning at the lower end of the valley. The fill will be delivered to the site by dump trucks. The material will then be spread by bulldozer into lifts. Type 3 compaction will be provided. Greater densification will occur as time goes by, but is not necessary as the site will be returned to forestry. Erosion and Sediment Control Requirement #1 Ground cover will be reestablished as the fill proceeds to limit the exposed soils to meet the requirements of Mason County Ordinance# 141-97. Exposed soils beyond the work area will be covered within 7 days. No sediment will be allowed to leave the site. Erosion and Sediment Control Requirement #2 Clearing limits will be clearly marked prior to any clearing of the site. No easements, setbacks, sensitive/critical areas or their buffers are in the vicinity of this project. Erosion and Sediment Control Requirement #3 No public or private properties exist within %2 mile of the subject site, therefore Erosion and Sediment Control Requirement #3 does not apply. Silt fence will be installed along the access road to insure what any mud or other debris from the trucks will not be washed by rainfall to any surface water. Erosion and Sediment Control Requirement#4 The nature of the existing topography does not allow sediment to leave the site. Sediment ponds will be installed and maintained at both the upper and lower extent of the fill. Erosion and Sediment Control Requirement #5 No cut slopes will be constructed as part of this project. The fill will be placed in the bottom of a natural draw. The only fill slopes to be created will be at the upstream and downstream ends of the fill where it meets the natural ground level. We anticipate that the fill will be slightly humped in the center to channel storm water to the edge of the fill where it abuts the existing slope. A grass-lined swale will be established along both edges of the fill as it proceeds down slope. This swale abutting the undisturbed soils of the valley sides will allow most of the storm water from the top of the fill to infiltrate into the ground in the same manner as is currently occurring. The down valley fill slope will be limited to a 3:1 slope and the swales will be directed to discharge into rock lined channels to protect the slopes. A rock check dam will be placed for each 2 feet of vertical drop on the fill slope. Erosion and Sediment Control Requirement #6 Not offsite erosion occurs from this site. No discharge of storm water offsite exists except the discharge to ground water previously described. This plan will maintain that condition. Erosion and Sediment Control Requirement#7 The sites ability to infiltrate the 2-year, 24 hour storm will be maintained. Stabilization as previously described will be provided to prevent erosion of drainage conduits or outlets, slopes and downstream reaches and to protect the discharges from all onsite conveyance systems. Erosion and Sediment Control Requirement#8 The measures described above are intended to protect the ability of the overall site to continue its function in the discharge of storm water to the ground water. Since this site does not currently have a manmade storm water control system and since none is proposed this requirement does not apply. Erosion and Sediment Control Requirement #9 This requirement does not apply in this instance, as no underground utility construction is included in this project. Erosion and Sediment Control Requirement #10 Construction vehicles will access the site via an existing private gravel haul road. The haul road is approximately 1/2 of a mile long and this will be adequate to limit the tracking of mud from the fill site back onto SR-101. The loading site at the SR-101 slide will require some attention. WSDOT will establish those procedures in their contract. Silt fences will be provided where required along the haul road as previously described. Erosion and Sediment Control Requirement #11 Any temporary erosion control BMP's will be removed within 30 days of final site stabilization. Any sediments collected will be removed and stabilized on site. All disturbed soils will be planted by hydroseeding and covered with mulch as required in Erosion and Sediment Control Requirement 41. Final site stabilization will be accomplished on a schedule while will allow the ground cover adequate time to estabilish itself. Erosion and Sediment Control Requirement #12 This requirement does not apply for this project. Erosion and Sediment Control Requirement #13 Litter, fuel or lubricating oils or other possible pollutants will be closely monitored during construction of this fill. All BMP's will be followed and any reports required by Mason County or other agencies with jurisdiction will be filed. Erosion and Sediment Control Requirement #14 All temporary erosion or sediment control features will be maintained during the life of this project. Permanent erosion or sediment control features will be maintained as required to maintain their intended functionality. STATE ENVIRONMENTAL POLICY ACT ENVIRONMENTAL CHECKLIST Purpose of Checklist: The State Environmental Policy Act (SEPA), chapter 43.21C RCW, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. 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 to Applicants: 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 your 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 now 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 difference parcels of land. Attach any additional information that will help 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. A. BACKGROUND 1. Name of proposed project, if applicable: Dave Robbins Hama Hama Company N. 35959 Hwy. 101 Lilliwaup, WA 98555 Fill and Grading Permit Application 2. Name of applicant: Quigg Brothers Incorporated 3. Address and phone number of applicant and contact person: Applicant: Quigg Brothers Incorporated P. O. Box 1707 819 West State Aberdeen, WA 98520 Contract Person: Mr. Tim Quigg 360-533-1530 4. Date checklist prepared: April 13, 1999 5. Agency requesting checklist: Mason County Planning and Building Departments 6. Proposed timing or schedule (including phasing, if applicable): Proposed fill to begin during late April or early May 1999 weather permitting. The applicant proposes a 2 year term for the permit due to the uncertainty of weather and difficulty of working on landslides. 7. Do you have any plans for future additions, expansion, or further activity related to or connected with this proposal? Nothing beyond a secondary desire on the part of the property owner and the applicant to make this site available for other projects so long as permitted capacity is available. Ultimate capacity of the site will be determined as this project proceeds through the permit process. 8. List any environmental information you know about that has been prepared, or will be prepared, directly relating to this proposal. None. 9. Do you know whether applications are pending for government approvals of other proposals directly affecting the property covered by your proposal? If yes, explain. None known at this time. 10. List any government approvals or permits that will be needed for your proposal, if known. None known at this time. 11. Give brief, complete description of your proposal, including proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) This project will provide for disposal of landslide debris from the Lilliwaup M.P. 326 and Ayock M.P. 322 landslides, which have blocked SR-101. The proposed fill site has no natural discharge except to ground water through infiltration. The site is very lightly timbered with non-merchantable trees that are suffering from root rot. The property owner wants to remove the few small trees and then cover the site with fill material. The land will be replanted with ground cover and trees following completion of the filling process. Provision will be made at both the upslope and downslope ends of the proposed fill to allow storm water to infiltrate into the pervious sands and gravels which underlay the site. This method of storm water control duplicates the existing condition. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. All of the work to be undertaken as part of this project is located within the South 1/2 of Section 27, Township 24 North, Range 3 West WM. Parcel # 32427-00-04000 B. ENVIRONMENTAL ELEMENTS 1. EARTH: a. General description of the site (circle one): Flat, rolling, hill steep slopes, mountainous, other What is the steepest sloe on the site (approximate percent b• P P ( PP slope)? Maximum slopes are in the 31% range in the area to be filled. This project will reduce cross slopes in the area of the fill and will leave the lower valleyslope at near current grades, but at a P somewhat higher elevation. The down slope end of the proposed fill will be limited to a 3:1 slope. Provisions will be made to control erosion from the fill. C. What general types of soils are found on the site (for example, clay, gravel, sand, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. The soil within the project area generally consists of sand and gravel with shallow topsoil or forest duff on or near the surface. The existing soils can be described as free draining. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. No e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Exact quantities of the proposed fill are not currently known, but the site has a capacity of more than 250,000 cubic yards. f. Could erosion occur as a result of clearing, construction, or use? If so generally describe. No. Construction work will include protective measures for the possible minor erosion problems. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? No impervious surfaces will be created as a result of this proposed project. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: Erosion control features will be constructed as the fill proceeds. The intent is to leave the site in a condition which will allow storm water to infiltrate into the ground in the same manner as currently exists. Straw bales, rock check dams and silt control fences will all be used. Silt fences and straw bails will be used along the existing haul road from SR-101 to the fill site. 2. AIR: a. What types of emissions to the air would result from the proposal (i.e. dust, automobile, odors, and industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. Dust and equipment exhaust, during construction. A water truck will be used if necessary to control dust generated by the trucks delivering material to the fill site. b. Are there any off-site sources of emissions or odor that may affect your proposal? If so, generally describe. The materials transport to the fill site by truck is also a potential source to emissions consisting of dust and exhaust emissions, but these are subject to other environmental regulation. Dust control on site will be provided as needed to limit offsite dust. C. Proposed measures to reduce or control emissions or other impacts to air, if any: None. Contractor's equipment is controlled by current regulations. 3. WATER: a. Surface: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. Yes, the Hama Hama River is approximately 1/2 mile away and Hood Canal is approximately 5/8 mile away, however no drainage from the proposed fill site directly enters either body of water. All stromwater from the site enters the groundwater. This project will leave that system intact. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. No 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. None 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. No. 5) Does the proposal lie within the 100-year flood plain? If so, note location on the site plan. No work is proposed within the 100 year floodplain. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. b. Ground: 1) Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities if known. No. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example, Domestic sewage; industrial, containing the following chemicals...; agricultural; etc..). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. None. C. Water Runoff(including storm water): 1) Describe the source of runoff (including storm water) and methods of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. No significant change in existing storm water drainage patterns will occur as a result of this project. See Section B, Article 1, Paragraph b for additional information. 2) Could waste materials enter ground or surface waters? if so, generally describe. No d. Proposed measures to reduce or control surface, ground and runoff water impacts, if any: Erosion control features will be constructed as the fill proceeds. The intent is to leave the existing pothole as the primary storm water control mechanism. The amount of open unrestored earth will be kept to a minimum to reduce the potential of plugging the underlying sands and gravel with fines. Straw bales, rock check dams and silt control fences will all be used. 4. PLANTS: a. Check or circle types of vegetation found on the site: Deciduous tree: alder, maple, aspen, other evergreen tree: fir, cedar, pine, other shrubs grass pasture crop or grain - None Known wet soil plants: cattail, buttercup, bulrush, skunk cabbage, other Water plants: water lily, eelgrass, Milfoil, other types of vegetation b. What kind and amount of vegetation will be removed or altered? Existing non-merchantable trees will be removed prior to the fill operation. The site will be replanted to forest after the fill process is complete. The existing trees in this area have root rot and the land owner believes the fill will provide better conditions for the replanting of the forest cover. C. List threatened or endangered species known to be on or near the site. None known. d. Proposed landscaping, use of native plants or other measures to preserve or enhance vegetation on the site, if any: Restoration of groundcover will be provided. 5. ANIMALS: a.
