Principal Engineer Department of Public Utilities Tacoma Power 3628 South 35th Street Tacoma,WA 98409 Addendum 1 to Geotechnical Report North Fork Skokomish Salmon Hatchery and Saltwater Park Sockeye Hatchery Hoodsport,Washington Dear Mr. Druffel: At your request, we prepared this addendum to the Geotechnical Report pr.-pared for the project referenced above. This letter provides additional information requested by Mason County to assist with their review of the project plans. Background Tacoma Power has designed new fish hatchery facilities to be constructed a:their North Fork site near Cushman Darn No. 2. Comforth Consultants prepared a geotechnical report for the project in December 2013. As part of the plans review process, Mason County requested additional information to address specific items in Mason County Ordinance 17.0 1.10 D—Landslide Hazard Areas. Responses to County Review Comments The following items provide additional information and/or clarification to address the County's review comments and questions. The comments are arranged and referenced as listed on the County form titled"Submittal Checklist For a Geotechnical Report." 1. Item #4. The County defines the slope on the east side of the North Fork site as a landslide hazard due to the presence of slopes steeper than 40 percent. The attached Figure I shows the proposed hatchery structures and the slope that is defined as a land Tide hazard. County Ordinance 17.01.100.D.6.a requires a 50-foot buffer of undisturbed, natural vegetation around an area defined as a landslide hazard. Natural vegetation can lower the potential for shallow slope instability and erosion, particularly near the crest of a sslope. The site of the proposed hatchery is currently a gravel parking lot at the toe of the slope. The parking lot I N 2251 extends to the toe of the slope. There is no native vegetation beyond tie toe of the slope, as shown in the picture below. From a geotechnical standpoint, there is no benefit from a vegetative buffer at this site. For this reason, we have shown our rec mmended buffer line coincident with the toe of the slope on Figure 1. y x f z. m r u 4 2. Item#7d. This comment relates to recommended vegetative buffers from the area defined as a landslide hazard. As discussed under Item #4, there is no geotechnical benefit from a vegetative buffer at this site, so no buffer is recommended. 3. Item #7e. This comment relates to recommended building setbacks fron the area defined as a landslide hazard, shoreline bluffs, and the tops of other slopes on the property. The North Fork Hatchery site is not near the top of any slope. Stability analyses summarized in the geotechnical report resulted in calculated factors-of-safety for slope stability of 1.50 and 1.13 under static and seismic conditions, respectively. Based on these results, the likelihood of a large-scale slope failure impacting the development is low. In our opinion, no setback is required.Figure 1 shows the recommended setback line coincident with the toe of the slope. 4. Item #10. This comment is related to on-site and off-site impa is of the proposed development on the area defined as a landslide hazard. In our opinion the proposed development has no on-site or off-site impacts on the stability of the slope. 5. Item #11. This comment is related to vegetative buffers for the propo ed development. As discussed in Item#4 above,vegetative buffers provide no geotechnical benefit at this site. June 7,2014 2 Co forth Consultants,Inc. 2251 We trust this addendum is sufficient for your current needs.

Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal.Please answer each question accurately and carefully,to the best of your knowledge. You may need to consult with an agency specialist or private consultant for some questions. You may use"not applicable"or"does not apply"only when you can explain why it does not apply and not when the answer is unknown. You may also attach or incorporate by reference additional studies reports. Complete and accurate answers to these questions often avoid delays with the SEPA process as well as later in the decision-making process. The checklist questions apply to all parts of ypur 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 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. Instructions for Lead Agencies: Additional information may be necessary to evaluate the existing environment,all interrelated aspects of the proposal and an analysis of adverse impacts. The checklist is considered the first but not necessarily the only source of information needed to make an adequate threshold determination. Once a threshold determination is made,the lead agency is responsible for the completeness and accuracy of the checklist and other supporting documents. Use of checklist for nonproject proposals: Please complete all questions that apply and note that the words "project," "applicant," and "property or site" should be read as "proposal," "proponent," and "affected geographic area," respectively.ADDITION, complete the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D).

General description of the site (circle one): Flat, rolling, hilly, steep slopes, mountainous, other b. What is the steepest slope on the site (approximate percent slope)? 2% on area to be developed. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. Sandy gravel over dense gravely sands. 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. Imported gravel surfacing and pipe bedding materials (2,000 cy estimated). The remainder of the site is a balanced cut and fill where existing topography is within a foot of final grade. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Not likely. The existing site is mostly cleared and the native sandy gravel soils are very free draining. Regardless, temporary erosion control provisions will be provided. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? SEPA Environmental checklist(WAC 197-11-960) guidance updated lfarch 2012 3 33%. Asphalt and buildings compose 1.49 acres of the 4.51 acre site. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: A construction storm water pollution prevention plan will be prepared. Generally it will employ perimeter silt fencing, use of straw bale check dams, a wet pond, and other relevant BMP's. 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. During construction equipment exhaust and possibly dust. After constructio i hatchery vehicle exhaust and hatchery odors. Hatchery odors are usually associated with fis 1 feed and effluent water treatment. b. Are there any off-site sources of emissions or odor that may affect your pror osal? If so, generally describe. No. c. Proposed measures to reduce or control emissions or other impacts to air, if any: This hatchery employs dual-drain circular rearing vessels where fish waste end uneaten food are swept into a center drain within minutes and go to a clarifier. Also, the fish rearing areas will be paved with concrete which will be washed down regularly into the clarifier which further limits the amount of uneaten feed that could produce odors. These actions will direct most of the odor to the clarifier which will be at the most remote end of the site away from residences, thus hatchery odor may be unnoticeable off-site. 3. Water a. Surface Water: 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. Lake Kokanee which is an impoundment of the North Fork Skokomish River. 2) Will the project require any work over, in, or adjacent to (within 200 feet) he described waters? If yes, please describe and attach available plans. Yes, the water supply and return pipelines lay within Lake Kokanee. ThE hatchery itself is approximately 300 feet from ordinary high water. SEPA Environmental checklist(WAC 197-11-960) guidance updated March 2012 4 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. 625 cubic yards of excavation for the pipeline trenches and 550 cubic yards to fill back in the trenches. Of the 550 cubic yards, 370 cubic yards will be gravel backfill for bedding the pipelines, and 180 cubic yards will be native glacial outwash that was excavated from the trench. The original grade of the bottom of the lake will be placed back to original elevation. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. Yes, a 6 cubic foot per second water right has been obtained for use of Lake Kokanee water. This water will be used for juvenile rearing and adult fish holding. 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. The hatchery upland site does not lie within the floodplain. The pipelines that traverse Lake Kokanee are within the 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. All of the water withdrawn for the hatchery will be returned to Lake Kokanee and discharged near the inlet for the river discharge at the base of the dam. This is subject to an NPDES permit currently under review. b. Ground Water: 1) Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities if known. The hatchery is purchasing ground water from the Lake Cushman Maintenance Company who obtained a water right to provide Tacoma with 100 gallons per minute. This water will be used for incubation of eggs. No discharge into the ground except for natural storm water infiltration and the on-site sewage disposal system. 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. An on-site sewage disposal system will be constructed for discharging waste from personal restrooms and utility sinks and will be sized for a maximum 375 gallons per day. The discharge material will be comparable to residential type discharges. c. Water runoff(including stormwater): SEPA Environmental checklist(WAC 197-11-960) guidance updated March 2012 5 1) Describe the source of runoff(including storm water) and method of coll ction and disposal, if any (include quantities, if known). Where will this water low? Will this water flow into other waters? If so, describe. The storm water system is composed of three elements. All runoff from paved surfaces is collected in catch basins directed to a storm water filter cartridge treatment system from which the water is discharged to Lake Kokanee. All runoff from roofs is ollected and discharged downstream of the filter cartridge system to Lake Kokanee. Runoff from the gravel boat launch parking expansion is treated in a wet pond and then infiltrates or overflows to Lake Kokanee. 2) Could waste materials enter ground or surface waters? If so, generally describe. Yes, however treatment measures are being employed for both storm water runoff and hatchery effluent as described previously. d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: The storm water treatment and hatchery effluent treatment systems previously described. 4. Plants a. Check or circle types of vegetation found on the site: X deciduous tree: alder, maple, aspen, other cottonwood X evergreen tree: fir, cedar, pine, other X shrubs X grass pasture crop or grain wet soil plants: cattail, buttercup, bullrush, skunk cabbage, other water plants: water lily, eelgrass, milfoil, other other types of vegetation b. What kind and amount of vegetation will be removed or altered? The boat launch parking lot expansion on the south end of the site will clear pproximately '/z acre of currently forested land that is medium size firs with salal underbrush. A small amount of additional clearing of the same vegetation type at the northeast corner of the site is needed for the water storage tank. c. List threatened or endangered species known to be on or near the site. None d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: SEPA Environmental checklist(WAC 197-11-960) guidance updated March 2012 6 Native vegetation will be left undisturbed beyond the hatchery and parking lot limits. Grass and landscaping will be planted between the hatchery and road on the west side. 5. Animals a. Circle any birds and animals which have been observed on or near the site or are known to be on or near the site: hf e birds: hawk, heron, eagle, songbirds, other: Pidgeon, crow, duck mammals: deer, bear, elk, beaver, other: ottor, racoon fish: bass, salmon, trout, herring, shellfish, other b. List any threatened or endangered species known to be on or near the site. For the hatchery site there are marbled murrelet. Management of buffer habitat for the northern spotted owl (Strix occidentalis) is indicated on the PHS list for this area; however, the proposed action would not result in any effect to this species or its habitat since no nesting trees would be removed, and forested habitat in the immediate project area is fragmented and disturbed. For Lake Kokanee there are bull trout; however bull trout critical habitat is not designated in Lake Kokanee (75FR 63979). c. Is the site part of a migration route? If so, explain. Yes, ducks and other migratory birds. d. Proposed measures to preserve or enhance wildlife, if any: The purpose of the hatchery is to preserve and enhance fisheries. 6. Energy and natural resources a. What kinds of energy (electric, natural gas, oil, wood stove, solar)will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. Electric for heating, lighting and water supply pumping. b.
