Other mitigation shall be required to prevent significant adverse environmental impacts, pursuant to M.C.C. Chapter 8.04 to 8.40. No mitigation is required because no damage to critical areas or their buffers has occurred. Mason County Resource Ordinance The issuance of this permit will not result in a violation of the Mason County Resource Lands and Critical Areas Ordinance. The site was inspected on October 22, 2024, by Luke Viscusi, of the Mason County Planning Department, who determined that any critical area buffer issues have been sufficiently documented. Project activities will partially occur within 300 feet of slopes with greater than 40%slopes, therefore a Geotechnical Report was submitted for the project(see below).All project activities are outside of wetland, stream, and landslide hazard area buffers. Geotechnical Report/Geological Assessment Review A Geotechnical Report and submittal checklist, dated August 8, 2024, prepared by Envirotech Engineering, PLLC, was approved by Luke Viscusi, of the Mason County Planning Department, as being complete on December 31, 2024, under case#GE02024- 00096.A 0-foot vegetation removal buffer and a 50 foot construction setback from the top of the slope exceeding 40% were recommended by the engineer. All future development must comply with the recommendations of the Geotechnical Report. Shoreline Master Program N A the proposal is not within shoreline jurisdiction. Flood Ordinance NIA, approval of this Moratorium Waiver will not violate the provisions of the Flood Damage Prevention Chapter of Mason County Code Title 14. State Environmental Policy Act This application for MOR2024-00006 has been reviewed for SEPA compliance under case #:SEP2024-00033. The SEPA record number is 202500011. (a) Is SEPA exempt.

Most Forest Practice Applications will have "land-disturbing"activities of 7,000 square feet or more, meaning that Minimum Requirements#1 through#5 of the Manual will generally apply. These minimum requirements are briefly described in pages 1 -4. A professional engineer is typically not required in these cases. Some FPAs may trigger the need to comply with all Minimum Requirements (#1-#10). These typically are projects where new road construction is necessary for harvest, particularly if there is also the need for a MEP and/or geotechnical report or study. A professional engineer is needed in these cases. Finally, some FPAs may be considered to have such a low potential for sediment or sediment-laden water leaving the site,that Minimum Requirement 42 (SWPPP) can be met by conditioning the FPA with the following conditions: 1. The boundaries of the clearing limits shown on this plan shall be clearly flagged in the field prior to construction. During the construction period, no disturbance beyond the flagged clearing limits shall be permitted. The flagging shall be maintained by the applicant/contractor for the duration of construction. 2. Stabilized construction entrances shall be installed at the beginning of construction and maintained for the duration of the project.Additional measures may be required to insure that all paved areas are kept clean for the duration of the project. 3. The ESC facilities shown on this plan are the minimum requirements for anticipated site conditions.During the construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and to ensure that sediment and sediment-laden water do not leave the site. PLEASE NOTE.In addition to County Code, applicants may need to obtain a Construction Stormwater General Permit(CSWGP)issued through the Department of Ecology. Page 1 of 9 FPA Stormwater Minimum Requirements Guide to Preparing Required County Submittals (last update: 09/2018) Minimum Requirement#1: Prepare a Stormwater site plan This minimum requirement will always apply, although in a much-abbreviated form of the full requirements for an engineered stormwater site plan. The site plan used for the SEPA and/or FPA application can be used as the stormwater site plan, if it includes the following information: 1. Note the construction access location and type of stabilization to be used to prevent tracking sediment off-site. 2. Identify the clearing limits, sensitive areas and their buffers, and any trees required for preservation. 3. Note the location of any proposed sediment controls to be used to contain sediments on-site. 4. Note the location of any soil and/or slope stabilization that will occur. S. Note the location of all natural and constructed drainage features on site and in the near vicinity. Natural features may be wetlands,streams,draws, ravines, springs, etc. and constructed features could include culverts, ditches,catch basins, ponds, dikes, berms, or others. The site plan should also provide a brief narrative of the project including: 1. Project location and any associated permit numbers 2. Total site acreage and the acreage to be disturbed (logged) a 3. Description of any new road construction(length,width, materials), or if existing roads re to be used, note this 4. Genera I description of soils, topography and drainage including where surface water enters and leaves the property 5. Anticipated start and end date 6. Description of logging method and expected use after logging /�/t= This narrative can be the same as that included in the beginning of the SWPPP template found on pages 3 through 7. Applicants may use information also included in SEPA, MEP, and/or FPA applications. Minimum Requirement#2: Prepare a Construction Stormwater Pollution Prevention Plan (SWPPP) This minimum requirement will also always apply and includes 12 elements. Depending on the project size, location, timing, and other considerations, some projects will need to address all 12 elements while others may only address a few. If an applicant feels that an element is not applicable, the rationale should be clearly described. See pages 3 through 7 for a FPA Construction SWPPP template applicants may choose to use. Page 2 of 9 FPA stormwater Minimum Requirements Guide to Preparing Required County Submittals Mast update: 09/2018) Some projects are small in nature, do not require a Construction Stormwater General Permit, have very limited ground disturbance, are generally flat, have little or no constructed stormwater conveyances or facilities, have no critical areas, and have soils with low erosivity potential. In these cases a SWPPP is not required but the FPA permit will be conditioned with the following: 1. The boundaries of the clearing limits shown on this plan shall be clearly flagged in the field prior to construction. During the construction period, no disturbance beyond the flagged clearing limits shall be permitted.The flagging shall be maintained by the applicant/contractor for the duration of construction. 2. Stabilized construction entrances shall be installed at the beginning of construction and maintained for the duration of the project.Additional measures may be required to insure that all paved areas are kept clean for the duration of the project. 3. The ESC facilities shown on this plan are the minimum requirements for anticipated site conditions. During the construction period, these ESC facilities shall be upgraded as needed for unexpected storm events and to ensure that sediment and sediment-laden water do not leave the site. Minimum Requirement#3: Pollution Source Control This minimum requirement will likely be N/A(not applicable) because most of the BMPs will already be addressed in Minimurn Requirement 42,the construction SWPPP. The applicant may want to call out those elements of the SWPPP that provide pollution source control;for example: "See Element 9 of the SWPPP,,, Minimum Requirement 44: Preserve Natural Drainage Systems and Outfalls The applicant should have provided a brief narrative of the natural drainage patterns and constructed drainage features on the property(Minimum Requirement#1), These locations should also be clearly identified on the site plan (also Minimum Requirement#1) with the note that they are to he protected to the maximum extent feasible. The applicant can repeat and/or reference the applicable sections from Minimurn Requirement#1. If drainage systems or features need to be altered,the applicant should note the possible downstream impacts and how they will be mitigated. Minimum Requirement#5: Manage stormwater On-Site Page 3 of 9 FPA Stormwater Minimum Requirements Guide to Preparing Required County Submittals (last update: 09/2018) To the maximum extent feasible, projects shall infiltrate, disperse, and retain stormwater runoff onsite to prevent flooding and erosion impacts. Most FPAs will manage stormwater onsite through dispersion and infiltration, and can simply note that under this minimum requirement. Sites that include steep topography, and/or erosive soils, low permeability, sensitive downstream areas may require additional onsite management features and the applicant should describe how this will be accomplished. Sites that require a geotechnical report or study,or MEP are potential candidates for additional on-site stormwater management beyond dispersion and infiltration. Page 4 of 9 FPA Stormwater Minimum Requirements Guide to Preparing Required County Submittals (last update: 09/2018) FPA Construction SWPPP Elements - Template Project description—Include the following information: 1. Project location and any associated permit numbers 2. Total site acreage and the acreage to be disturbed (logged) 3. Description of any new road construction (length, width, materials),or if existing roads are to be used, note this 4. General description of soils,topography and drainage including where surface water enters and leaves the property 5. Anticipated start and end date and any other project timing considerations 6. Description of logging method and expected use after logging Element 1: Mark Clearing Limits To protect adjacent properties and to reduce the area of soil exposed to construction, the limits of construction will be clearly marked before land-disturbing activities begin. Trees that are to be preserved, as well as all sensitive areas and their buffers, shall be clearly delineated, both in the field and on the plans. In general, natural vegetation and native topsoil shall be retained in an undisturbed state to the maximum extent possible. Applicant should describe how clearing limits will be marked prior to logging and note on the site plan. Element 2: Establish Construction Access Construction access shall be established and access points shall be stabilized to minimize the tracking of sediment onto public roads. If sediment is tracked off site, public roads shall be cleaned by shoveling or sweeping at the end of the day to prevent sediment from entering surface waters. Applicant should describe where the construction access will be, obtain a Road Access Permit if it is a new location, and construct access to minimize sediment tracking. # \ Element 3: Control Flow Rates Downstream properties and waterways shall be protected from erosion due to increases in stormwater runoff volume,velocity and peak flow rate. The applicant needs to clearly identify where runoff will leave the site so potential downstream impacts can be evaluated. This element will be "not applicable" (N/A)for most FPAs because the increase in runoff and/or erosion due to logging will be negligible. If no BMPs are proposed,the applicant needs to describe rationale: e.g.,flat topography, highly permeable soils, large vegetated buffers at site perimeter, logging method, others. Page 5 of 9 FPA Stormwater Minimum Requirements Guide to Preparing Required County Submittals (last update: 09/2018) Element 4: Install Sediment Controls Stormwater runoff from disturbed areas shall pass through a sediment removal Best Management Practice (BMP) before leaving the site or prior to being discharged to an infiltration facility. In most cases, an FPA will not require the construction of an infiltration facility. Whenever possible, sediment laden water shall be discharged into onsite, relatively level,vegetated areas. If no BMPs are proposed, the applicant needs to describe rationale. More complex sediment control/treatment BMPs, such as infiltration facilities, should be used if sediment controls are not(or not anticipated to be) adequate for the site-specific construction activities. These BMPs are primarily used on: • Larger sites(i.e. greater than 5 acres), or, ■ Sites that have continual soil disturbance and are difficult to temporarily stabilize, or, • Sites at higher risk of erosion (i.e.slopes), or, ■ Sites where the downstream environment is particularly sensitive and more stringent discharge controls are required. rya, Element 5: Stabilize Soils Exposed and unworked soils shall be stabilized with the application of effective BMPs to prevent erosion throughout the life of the project. In general, cut and fill slopes will be stabilized as soon as possible and soil stockpiles will be temporarily covered with plastic sheeting. All stockpiled soils shall be stabilized from erosion, protected with sediment trapping measures, and where possible, be located away from storm drain inlets,waterways, and drainage channels. This element will be "not applicable" (N/A)for most FPAs unless there is new road construction that includes cuts and fills. If no BMPs are proposed, the applicant needs to describe rationale. Element 5: Protect Slopes All cut and fill slopes will be designed,constructed, and protected in a manner that minimizes erosion. This element will be "not applicable"(N/A)for most FPAs unless there is new road construction that includes cuts and fills. If no BMPs are proposed, the applicant needs to describe rationale. Element 7: Protect Drain Inlets All storm drain inlets and culverts made operable during construction shall be protected to prevent unfiltered or untreated water from entering the drainage conveyance system., However, the first Page 6 of 9 FPA Stormwater Minimum Requirements Guide to Preparing Required County Submittals (last update: 09/2018) priority is to keep all access roads clean of sediment and keep street wash water separate from entering storm drains until treatment can be provided. Storm Drain Inlet Protection(BMP C220)will be implemented for all drainage inlets and culverts that could potentially be impacted by sediment-laden runoff on and near the project site. /,,o 1 .� d�� r14 /:Uao/1 This element will be "not applicable"(N/A)for most FPAs unless there is new road construction that includes cuts and fills. If no BMPs are proposed, the applicant needs to describe rationale. Element 8: Stabilize Channels and Outlets Where site runoff is to be conveyed in channels, or discharged to a stream or some other natural drainage point, efforts will be taken to prevent downstream erosion. The general project description and site plan should identify where runoff will leave the site at natural drainage points. This element will be "not applicable"(N/A)for most FPAs unless there is new road construction, existing roads with culverts and conveyances, resource protection areas,steep slopes,and/or highly erosive soils. If no BMPs are proposed, the applicant needs to describe rationale. f Element 9: Control Pollutants N - All onsite pollutant sources shall be handled and disposed of in a manner that does not cause contamination of stormwater. Good housekeeping and preventative measures will be taken to ensure that the site will be kept clean,well organized,and free of debris. Applicant should describe all potential pollution sources and how they will be managed. u,/„ K Element 10: Control De-Watering This element will be "not applicable"(N/A)for most FPAs. Element 11: Maintain BMPs All temporary and permanent erosion and sediment control BMPs shall be maintained and repaired as needed to assure continued performance of their intended function. Maintenance and repair shall be conducted in accordance with each particular BMPs specifications. Visual monitoring of the BMPs will be conducted at least once every calendar week and within 24 hours of any stormwater or non- stormwater discharge from the site. If the site becomes inactive, and is temporarily stabilized, the inspection frequency will be reduced to once every month. All temporary erosion and sediment control BMPs shall be removed within 30 days after the final site stabilization is achieved or after the temporary BMPs are no longer needed. This element will be "not applicable"(N/A)for most FPAs if Element 3's 3—8 are N/A or very minimal. G V Page 7 of 9 r FPA Stormwater Minimum Requirements Guide to Preparing Required County Submittals (last update: 09/2018) Element 12: Manage the Proiect Erosion and sediment control BMPs for this project have been designed based on the following principles (not all will be applicable): .� • Design the project to fit the existing topography, soils, and draina patterns. ■ Emphasize erosion control rather than sediment control. • Minimize the extent and duration of the area exposed. 00 Keep runoff velocities low. ' Retain sediment on site. • Thoroughly monitor site and maintain all ESC measures. / • Schedule major earthwork during the dry season. In addition, project management will incorporate the key components listed below (again, not all will be applicable): Seasonal Work Limitations • From October 1 through April 30, clearing, grading,and other soil disturbing activities shall only be permitted if shown to the satisfaction of the local permitting authority that silt-laden runoff will be prevented from leaving the site through a combination of the following: ❑ Site conditions including existing vegetative coverage,slope, soil type, and proximity to receiving waters; and ❑ Limitations on activities and the extent of disturbed areas; and ❑ Proposed erosion and sediment control measures. ' Based on the information provided and/or local weather conditions, the local permitting authority may expand or restrict the seasonal limitation on site disturbance. L'9 Page 8 of 9 w , FPA Stormwater Minimum Requirements Guide to Preparing Required County Submittals (last update: 09/2018) ■ The following activities are exempt from the seasonal clearing and grading limitations: ❑ Activities where there is 100 percent infiltration of surface water runoff within the site in approved and installed erosion and sediment control facilities. r! !L Coordination with Utilities and Other Jurisdictions ' Care has been taken to coordinate with utilities,other construction projects, and the local jurisdiction in preparing this SWPPP and scheduling the construction work. C Inspection and Monitoring ' All BMPs shall be inspected, maintained, and repaired as needed to assure continued performance of their intended function. ' Whenever inspection and/or monitoring reveals that the BMPs identified in this SWPPP are inadequate, due to the actual discharge of or potential to discharge a significant amount of any pollutant, appropriate BMPs or design changes shall be implemented as soon as possible.
