PROJECT INFORMATION: 1) LandownerlAnplicant: Bruce Seton Jr. 4640 S Discovery Road Port Townsend, WA 98368 2) Representative: Lisa Mahr Northwest Mining Solutions P.O. Box 561 Black Diamond, WA 98010 3) Location: The 23.6-acre parcel located at 225 Four Corners Road in Jefferson County Washington (APN 001332016). The parcel is situated immediately south of the Jefferson County International Airport, northwest of the intersection of State Route 20 and Four Corners Road. This property is located within Section 33 — Township: 30N — Range 1W. 4) Access: This site is accessed from the west off of State Route 20 through an existing easement through two parcels owned by the Port of Port Townsend. Prior to operation, a WSDOT Access Connection Permit will be required. 5) Property Characteristics: The site on which this Conditional Use will occur is 23.6-acres in size, rectangular in shape, and largely forested. The subject parcel is zoned Rural Residential 1 Unit/10 Acres (RR 1:10). The purpose of this zoning district is to provide a transitional area between the rural residential one per five -acre district and the rural residential one unit per 20-acre district. Its intent is to preserve open space, protect critical areas, provide for the continuation of small-scale agricultural and forestry, and preserve and retain the rural landscape and character indigenous to Jefferson County (per Section 18.15.015 JCC). RR 1:10 zoning allows for mineral extraction activities without a Mineral Resource Land (MRL) overlay ZON2024-00012 on parcels 10 acres or larger through a Conditional Use Permit, per 18.15.040 JCC Table 3-1. The Mineral Extraction, Mining and Reclamation performance standards found in section 18.20.240(1)(b) limits these activities to 10 acres of disturbed area at any one time without an MRL. 6) Existing Conditions On -Site: The parcel is relatively level and forested with an understory and conifers averaging 12-16" in diameter. Within the northwest corner of the parcel, an area of roughly 1.75 acres has previously been cleared of vegetation and excavated to a depth of about ten feet. This area is within the footprint of the proposed mining site. 7) Surrounding Development: The surrounding area contains multiple types of uses and zoning designations. An area of approximately 310 acres located to the north and east of this proposal is zoned Essential Public Facilities — Airport (AEPF). This is the site of the Jefferson County International Airport (JCIA). This zoning district is intended to promote compatible land uses and the long-term economic viability of the JCIA consistent with county goals regarding essential public facilities, the preservation of rural character, and economic development. The airport is owned and operated by the Port of Port Townsend (the Port). To the east are two undeveloped parcels which are part of the AEPF complex owned by the Port. The more southerly of these is a 23.6 acre currently going through a Conditional Use Permit to approve a Binding Site Plan (SUB2005-00007). The purpose of which is to create 11 lots of approximately one acre each, which can then be leased and developed according to the commercial and light industrial uses allowed under AEPF zoning. To the south of the proposed Conditional Use are eight parcels zoned Rural Residential 1 Unit per 5 acres. Seven of these parcels are roughly one acre in size and contain single family residences. The remaining parcel is approximately 5 acres and contains a residence along with a commercial nursery approved through Conditional Use Permits ZON1994-00007 and ZON1995-00002. The residences on these eight parcels are approximately 120 —150 feet from the northern property line, adjacent the proposed Conditional Use. On the western edge of the parcel, the majority of the property line is bordered by a 10.63-acre parcel zoned RR 1:10 and owned by Jefferson Transit. This site contains the Jefferson County Transit Facility, permitted through ZON2013-00023, approved on February 6, 2014, and implemented through BLD2014- 00004, which was completed on August 20, 2015. This complex contains the administrative offices, maintenance and operations center, as well as a fueling and bus wash station. 8) Proposal: The applicant is proposing to establish a new sand and gravel mining operation called the Four Corners Sand & Gravel Pit. The description of the proposal is outlined in the following exhibits: Site Development Review — SDR2024-00227 (Exhibit 3), Project Narrative (Exhibit 4), Project Site Plan (Exhibit 5), Reclamation Plan (Exhibit 6). The intention of this proposal will be to provide construction aggregate for use in local development projects. The mineral extraction process would utilize the western 9.14 acres of the 23.6-acre parcel. The mining would entail excavating down to 30 feet below the current ground level, yielding an estimated 333,000 cubic yards of material throughout the lifetime of the proposal. Because this mining operation is intended to support local projects, the site will operate on an "as -needed" basis. While actual production volumes will be dependent on demand, it's estimated that 10,000 cubic yards of material will be transported from the site annually. This would require an average ZON2024-00012 of 4-5 truck trips per day (round trip traffic for two to three dump trucks) A 50-foot forested buffer will be maintained between all disturbed areas and the surrounding property lines. Clearing the timber from the site will be done through an FPA Class IV General Permit issued through the WA State Department of Natural Resources (DNR). All topsoil and organic "over -burden" will scaped clear and staged on -site to be used during the final reclamation process. Mining would occur in two phases beginning on the northwest quarter of the site, and proceeding to the southwest quarter of the site. The heavy equipment to be used will consist of excavators, loaders, dump trucks and a portable rock crusher. A haul road will be constructed on the northern wall of the pit. As the pit floor is established and expanded, it will contain a stormwater infiltration pond as well as a processing area. The processing area will host the rock crushing equipment, stockpiles of material, and a shipping container to be used for equipment storage. Upon reaching final depth, the side walls will be graded to a 2:1 slope and the site reclaimed to forestry use. Prior to beginning operations, the proposal will require a reclamation permit from the DNR. Reclamation will occur in accordance with the approved reclamation plans (Exhibit 6). 9) Critical Areas: The Jefferson County Critical Areas Map identifies two types of Critical Areas as existing on this parcel._ Geologically Hazardous Area - Seismic Hazard. Also, a Critical Aquifer Recharge Area - Susceptible Aquifer Recharge Area + a Special Aquifer recharge Protection Area. Seismic Hazards are defined by WAC 365-190-030 as areas at elevated risk of damage by earthquake induced ground -shaking and liquefaction. Jefferson County Critical Area Ordinance does not regulate activities or address protection standards within seismic hazard zones. Due to the limited scope of operations and few personnel on -site, seismic hazards constitute a minimal risk to this proposed use. The Critical Area Maps also identify this parcel as being within a Critical Aquifer Recharge Area (CARA) (Exhibit 32). Specifically, a Susceptible Aquifer Recharge Area and Special Aquifer recharge Protection Area (SARPA). JCC 18.20.240 identifies the performance standards applicable to mineral extraction, mining, quarrying and reclamation. A Hydrogeologic Report Addendum by GeoResources dated April 4, 2025, was submitted to address the specific requirements described in 18.20.240 (2)(b) — (h) (exhibit 19). This report assesses the region's hydrogeologic characteristics and potential impacts to the area's aquifers. The author determined that the removal of sand and gravel to 30 feet below existing grade is unlikely to negatively impact groundwater resources. JCC 18.20.240 (2)(h)(i) requires that proposals for mineral extraction within a designated critical aquifer recharge area must submit a scope of work and site evaluation report to Jefferson County for review and approval. It has been determined by the Uniform Code Administrator that because mining is not considered a "High Impact Activity" under 18.22.330(1) JCC, and that the elements to be addressed through the site evaluation are covered in the geotechnical assessment and hydrogeologic report addendum, this requirement has been satisfied and can be waived under JCC 18.22.910. This waiver has been submitted and approved by the UDC Administrator, and entered into the record as exhibit 21. 10) Studies Submitted: Geotechnical Assessment by DE -Civil, PLi_C, dated February 12, 2025 (exhibit 20). This report provides a geotechnical assessment and civil engineering recommendations for the proposed mining activities. A site visit on January 24, 2025 found no evidence of surface water, erosion or site instability. This report also analyzed well -logs for the 33 known wells within the immediate area of the project. Hvdrogeologic Report Addendum by GeoResources dated April 4, 2025 (exhibit 19). This report ZON2024-00012 addendum supplements DE-Civil's geotechnical assessment, and also satisfies the requirement by 18.20.240 (2)(b) that "applications for development permits for extraction shall be accompanied by a report prepared by a professional geologist". It provides detail on the quantity and quality of each type of marketable material present, the lateral extent and depth of deposits, the depth of overburden and methods of extraction. Additionally, this report provides detail on hydrogeologic conditions and addresses the requirements of 18.20.240(h)(ii). Specifically, the permeability of the unsaturated zone, location of nearby sensitive wells, groundwater depths and flow direction, information on wells within one -quarter mile of the subject site, a site map, activity characterization, proposed best management practices and a contingency plan. 11) Required permits: • National Pollution Discharge Elimination System (NPDES) Sand & Gravel Permit - Dept. of Ecology • Notice of Construction (NOC) — Olympic Region Clean Air Agency (ORCAA) • Forest Practice Application —Type IV General Permit— DNR ■ Surface Mine Reclamation Permit —Department of Natural Resources (DNR) • WSDOT Access Connection Permit to access to State Route 20. 12) Public Noticing Requirements: Application Received Date: December 17, 2024 Application Complete Date: January 14, 2025 Public Notice of Application: May 15, 2025 (Exhibit 12) Posted on property, May 15, 2025 Mailed to adjacent property owners: May 15, 2025 (Exhibit 13) Sent to Tribes and Agencies: May 15, 2025 Public Comment closing date: May 29, 2025 13) State Environmental Policy Act Review: The proposal is subject to review under SEPA. Following a staff review of the SEPA checklist, a SEPA memo was drafted to provide clarity to DCD's position on the applicant's checklist responses (Exhibits 10 & 11). DCD issued a preliminary Determination of Non -significance was issued by Jefferson County on May 15, 2025 (Exhibit 12). The optional DNS process described in WAC 197-11-355 was utilized. The following summarizes comments received during the two -week Public Noticing Period ending May 26, 2025. The FINAL SEPA determination was issued on August 26, 2025. (Exhibit 15) a) Mr. Edward Johnson arrived in person at the DCD office on May 19, 2025 to make known his desire to be a party of record for this proposal. Mr. Johnson and his wife own a landscaping nursery on a parcel to the south of the proposed Conditional Use. A letter from his attorney was delivered to DCD on May 27, 2025 (Exhibit 22). This letter contained comments addressing anticipated impacts in the following areas: negative impacts to wildlife habitat, traffic and safety concerns, and an acceptable increase in noise and dust to local residents. The letter stated that to due to the high likelihood significant adverse impacts, and Environmental Impact Statement (EIS) must be created. This letter also contained a number of requests for modifications to the proposal to reduce the expected impacts to adjacent property owners. These requests were as follows: ZON2024-00012 • Increasing the forested buffer area from 50-feet up to 100-feet. • A request to modify the proposed backslope from a 2/1 length/height ratio to a 4/1 ratio with the intention of creating shallower, safer slopes. • To construct a 10-foot or higher earthen berm around the perimeter of the project to deflect noise and increase safety. • The fourth request related to the possibility of a second access road being established to the south of mining operation, allowing a connection to Four Corners Road. ■ The property owner requested that the applicant sign an agreement of intent regarding their concerns about starting work on one phase of the project before the previous phase had been completed, the expected longevity of the project, and the intended use for the eastern portion of the subject parcel. • Lastly, the property owner expressed concern that the removal of trees would increase the light pollution reaching his parcel from the airport. The applicant responded in writing to Mr. Johnson's requests on August 7, 2025. A copy of this correspondence was provided to DCD, and is entered into the record as exhibit 23. This letter outlines the reasons in which an EIS was not an appropriate requirement for a project of this scale. It also provided additional information on the expected operations with the goal of reducing the neighbor's concerns about the anticipated level of activity. The letter does contain two points in which the applicants was willing modify the project to mitigate possible impacts. The applicant agreed to construct a ten -foot earthen berm around the project perimeter to reduce noise and improve safety. Also, the applicant agreed not to pursue a secondary access to the site at this time. Staff comment: With the exception of the northern and western property boundaries where this parcel abuts the airport and Jefferson Transit facility, DCD is recommending a 10-foot-high berm along the perimeter of the excavation area that will be planted with conifers at 15-feet on center. b) An email dated May 15, 2025 was received from Nicole Gauthier, General Manager at Jefferson Transit Authority (exhibit 26). This email stated, "When reviewing this project, I would like to stress the importance of the bus stop that is located on Highway 20. See below for the Google map. It's important to Jefferson Transit and the community members that use this bus stop that it is not compromised. There are not a lot of places on Highway 20 where a bus stop is feasible. I would appreciate further information if the site for the access road is changed from the original plans." Staff comment: According to the "Site Generated Traffic Volumes" memo produced by the applicant (exhibit 8), it is expected that operations will result in 4-5 truck trips per day. It is unlikely that this volume will negatively impact the ability of Jefferson Transit busses to safely access the existing bus stop. c) An email dated May 15, 2025 was received from Andy Larson with Washington State Department of Transportation (Exhibit 27). It stated: "This notice shows an existing access from this parcel to SR 20, but the permit for that access does not include this parcel. If they intend to directly access SR 20, they will need to apply for that access and provide a Traffic Impact Analysis (TIA) for their impacts to the highway." Staff comment: After reviewing the "Site Generated Traffic memo" referenced above, WSDOT determined a Traffic Impact Analysis was not necessary. Access Connection Permit # ACP-62359 is ZON2024-00012 under review by WSDOT. An unsigned draft of this permit is included as exhibit 29. d) An email dated May 14, 2025 from John Fleming, with Jefferson County Public Works (Exhibit 28). It stated that the stormwater design "looked good", that they had existing access off of State Route 20, and that access off of Four Corners Road would be possible if an easement under the powerlines was granted and a Road Approach Permit was approved through Public Works. Staff comment: No secondary access is being requested at this time. e) An email dated May 15, 2025 was received from Abi Roberts, with Olympic Region Clean Air Agency (Exhibit 25). It stated that due to rock crushing operations, either a Notice of Construction permit (NOC), or Notice of Intent permit (NOI) would be required. Staff comment: An approved NOC or NOI permit will be required as a Condition of Approval for this proposal. f) An email dated May 28, 2025 was received from WA State Dept. of Ecology, containing comments from three distinct departments (Exhibit 24). The comments submitted are as follows: SOLID WASTE MANAGEMENT: Derek Rockett 360 995-3176 All grading and filling of land must utilize only clean fill. All other materials may be considered solid waste and permit approval may be required from your local jurisdictional health department prior to filling. All removed debris resulting from this project must be disposed of at an approved site. Contact the local jurisdictional health department or Department of ecology for proper management of these materials. Staff Comment: See comment below in "Water Quality/General Permits Unit". TOXICS CLEANUP: Dean Malte (360) 999-9584 One underground storage tank (UST) site (Jefferson County P.UD No. 1, FSID 7125893) is located within 750 feet of the project area to the south-southwest. The site has two active USTs containing gasoline and diesel fuel. No releases are associated with the USTs at this site, and it does not appear to be a concern for the proposed work. However, if any contamination is unexpectedly encountered anywhere in the project area, it must be reported to Ecology (per WAC 173-340-300) via the online ERTS portal. WATER QUALITY/GENERAL PERMITS UNIT: Eli Newby, Sand & Gravel Permit Manage (360) 763-2633, eli.newbv@ecv.wa.gov All new facilities and un-permitted existing facilities that intend to obtain coverage, and permitted existing facilities planning a significant process change must submit a complete and accurate notice of Intent (NOI). The Permittee must submit the NOI no less than one hundred and eighty (180) days before beginning any activity that may result in the discharge of any pollutant. No discharge is authorized until the effective date of permit coverage. Please include all planned activities and associated wastewater discharges to occur under Sand and Gravel General Permit coverage (Permit Conditions S.1, Tablel: Sand& Gravel General Permit- Washington State Department of Ecology) in the SEPA checklist and applicable studies to ensure the SEPA decision is appropriate for Ecology permitting without the need for SEPA revision. Please review "Defining the entire proposal' at: Lead agency determination and responsibilities — Washington State Department of Ecology for more information. (emphasis added) ZON2024-00012 Staff comment: The applicant will acquire a Sand & Gravel Permit after receiving approval for this Conditional Use from Jefferson County. Maintaining Ecology permit coverage for the duration of mining operations will be a conditional of approval for this permit. It is not anticipated that any fill will need to be brought on -site for either final regrading or reclamation work. If fill is required, it must be from an approved source and free of any invasive or noxious plant species. B. Notice of Public Hearin In accordance with the Type III permitting process described in 18.40.230 JCC, the public hearing was noticed as follows. (Exhibit 16) Notice of Public Hearing posted on property: August 27, 2025 Notice sent to adjacent property owners and Parties of Record: August 27, 2025 (exhibit 17) Notice posted in Port Townsend Leader: August 27, 2025 (exhibit 18) Public Comment closing date: September 10, 2025 Public Hearing: September 10, 2025 Pursuant to 18.40.810 JCC, a Conditional Use Permit application is processed as a Type III Permit. Any SEPA appeals will be addressed as part of this open record Public Hearing. 1. 18.40.530 Anoroval criteria for all conditional uses. a) The conditional use is harmonious and appropriate in design, character and appearance with the existing or intended character and quality of development in the vicinity of the subject property and with the physical characteristics of the subject property; Applicant response: The proposed mining activity is consistent with the character, design, and appearance of existing and intended development in the vicinity of the subject property. Although located within the RR-10 zoning district, mining is expressly permitted through a Conditional Use Permit (CUP), recognizing its potential compatibility under appropriate site conditions. The subject property is adjacent to the Jefferson County International Airport and is surrounded by multiple parcels owned by the Port of Port Townsend and Jefferson Transit, both of which support transportation and industrial functions. The immediate area is already characterized by heavy industrial uses and transportation infrastructure, contributing to a development pattern that is distinctly non-residential and operational in nature. Given the physical characteristics of the site and its proximity to existing industrial and transportation uses, the proposed mining operation is harmonious with the surrounding land use context and represents an appropriate and compatible use of the property. Staff comment: This parcel is located at the transition between residential and non-residential zoned parcels. To the south are seven RR 1:10 zoned parcels developed with single family residences. To the north is Jefferson County International Airport. The parcel to the East is owned by the Port of Port Townsend, who has applied for a Binding Site Plan under project number SUB2025-00007. This would allow the 23.62-acre parcel to be divided into 11 lots for individual development and light industrial use. The primary parcel to the west hosts Jefferson Transits administrative offices and maintenance facilities. The varied nature of the development in this neighborhood lends itself to the proposed sand and gravel pit. The 50-foot forested buffer will provide a visual screen and help to dampen noise to the surrounding lots. With the exception of the property line adjacent the airport and the Jefferson County ZON2024-00012 Transit Facility, DCD is recommending a 10-foot-high berm to be constructed and planted with conifers at 15 feet on center. b) The conditional use will be served by adequate infrastructure including roads, fire protection, water, wastewater disposal, and stormwater control; Applicant response: All of these aspects are covered within our narrative and supported by studies conducted on -site. This project is a small grading project and will be operation on an as needed basis for small projects within the area. Staff comment: The road to be used for accessing this parcel has been reviewed and approved by WSDOT. Because no permanent structures are being proposed, no water service or wastewater disposal will be on site. Stormwater will be managed by grading all slopes and ditches to direct runoff towards an engineered infiltration pond, which will be addressed in the Ecology NPDES Sand & Gravel Permit for this proposal. (c) The conditional use will not be materially detrimental to uses or property in the vicinity of the subject parcel; Applicant response: This is a small operation that will have limited impacts on the surrounding parcels. Every precaution has been planned for to help minimize impacts. This location was selected due to its proximity to the airport and the need for construction aggregates in the area. Staff comment: Because the purpose of this mining operation is to supply material for regional construction projects, it's periods of greatest activity will predominately be during construction season, which typically lasts from April through October. This coincides with the months of heightened tourist traffic along SR 20, and increased air traffic at Jefferson County International Airport. This should reduce the likelihood that any new disturbances will cause a nuisance to nearby residential development. (d) The conditional use will not introduce noise, smoke, dust, fumes, vibrations, odors, or other conditions or which unreasonably impact existing uses in the vicinity of the subject parcel; Applicant response: The site has incorporated mitigation measures to minimize noise and dust impacts. Crushing operations will occur on an as -needed basis and only during standard working hours as approved by the County. To preserve natural screening, land disturbance will be limited, maintaining, the vegetative setback for as long as feasible. A 50-foot vegetative buffer and 10-foot-high earthen berm will be maintained along the perimeter of the pit. Additionally, water will be used for effective dust suppression during operations. Staff comment: The limited hours of operation will result in the mining operations creating similar patterns of noise disturbances as the adjacent roads and airport. Noise, dust, and vibrations may extend onto adjacent properties. The potential for noise and vibration impacts to adjacent properties should be significantly reduced by the 10-foot earthen berm and 50-foot forested buffer. A conditional of approval will be created that a water -truck will remain available during all dry season operations. See also Section B(1)(a) above. (e) The location, size, and height of buildings, structures, walls and fences, and screening vegetation for the conditional use will not unreasonably interfere with allowable development or use of ZON2024-00012 neighboring properties. Applicant response: The site is not expected to have any impact on neighboring parcels in this way. There will be no permanent structures erected. All equipment on site will be temporary. Signs will be placed around the perimeter of the mining limits. A 50-ft vegetated setback will remain from the property boundary to help screen and minimize impacts to the surrounding parcels. Staff comment: There are no permanent structures planned for this this project. Warning signs and an earthen berm around the perimeter will prevent unintentional trespass into areas of active mining operations. Development and use of nearby properties will not be affected. (f) The pedestrian and vehicular traffic associated with the conditional use will not be hazardous to existing and anticipated traffic in the vicinity of the subject parcel. Applicant response: The site will not produce any pedestrian traffic and will produce minimal amount of truck traffic to the surrounding area. Truck traffic will be based on market need. The Site Generated Traffic Volumes analysis shows that on a peak day the site can produce up to 8 trips in a day. Staff comment: An Access Connection Permit approved by WSDOT must be issued prior to implementing the proposed Conditional Use. Based on the number of employees expected to be on site during normal operations, a bus -stop is not required for this mining proposal. (g) The conditional use complies with all other applicable criteria and standards of this title and any other applicable provisions of the Jefferson County Code or state law; and more specifically, conforms to the standards contained in Chapters 18.20 and 18.30 JCC; Applicant response: The proposed use complies with Jefferson County Code. See site plans and reports for site details. Staff comment: This Conditional Use meets all applicable development and performance standards within the UDC. (h) The proposed conditional use will not result in the siting of an incompatible use adjacent to an airport or airfield; Applicant response: The site will have no impacts on the neighboring airport. Staff comment: No permanent lighting or structures are proposed as part of this development. Mining and mineral extraction are not listed among the "prohibited uses" for Airport Overlay II zoning designation per 18.15.452 JCC. All dust generated during operations will be addressed through the Clean Air Authority Permit (ORCAA). To reduce the amount of dust vehicular traffic, DCD recommends that the access and haul roads be graveled. (i) The conditional use will not cause significant adverse impacts on the human or natural environments that cannot be mitigated through conditions of approval; Applicant response: Site operations will be minimal and driven by local market demand. Annual production is estimated at approximately 10,000 cubic yards, resulting in intermittent activity rather ZON2024-00012 than continuous or daily operations. The site will operate only as needed, with production levels adjusted based on regional demand. The site has many mitigation measures in place to reduce the impacts on the surrounding area. Staff comment: The Conditional Use is being proposed within a forested area with no identified critical areas. The parcel is surrounded on three sides by existing development. The forested, 23-acre parcel to the east, owned by the Port of Port Townsend, is currently the subject of a Binding Site Plan for a light industrial park (SUB2025-00007). Due to the high levels of surrounding development, the forested areas serve more as a visual and noise buffer, rather than beneficial wildlife habitat. The 50-foot forested buffer will allow these functional benefits to be maintained, while the site's timber will be both harvested and replanted through reclamation permits issued by DNR. (j) The conditional use has merit and value for the community as a whole; Applicant response: The proposed Conditional Use provides clear merit and long-term value to the community by supporting essential resource development that contributes directly to the local economy. Surface mining operations supply critical material for infrastructure, construction, and public works projects throughout the region. These activities not only create jobs and support local businesses, but also reduce reliance on imported materials, helping keep costs down for public and private development. When responsibly managed, mining serves as a foundational industry that enables growth, supports regional planning goals, and strengthens the economic resilience of Jefferson Cou nty. Staff comment: The conditional use will be an economic asset to the community and establish another local source of a material that is necessary for most types of development projects. Creating a new reserve of construction aggregate near Port Hadlock may reduce construction costs within Port Townsend's urban growth area which will come online once the new sewer system is operational. (k) The conditional use is consistent with all relevant goals and policies of the Jefferson County Comprehensive Plan; and Applicant response: This project directly aligns with Jefferson County Comprehensive Plan as it supports the economy, will produce jobs, and provides needed materials for growth in infrastructure and transportation. Staff comment: The proposal is consistent with the Comprehensive Plan's goals and policies. Specifically, Comprehensive Plan Policy NR-P-1.4 which states, "Locate natural resource -based economic activities throughout rural areas in close proximity to designated agricultural, forest or mineral resource lands upon which they are dependent. (1) The public interest suffers no substantial detrimental effect. Consideration shall be given to the cumulative effect of similar actions in the area. Applicant response: The site has many mitigations in place to reduce the effects of the site on the neighboring public. See site plans and accompanied reports for details. ZON2024-00012 Staff comment: The hydrogeologic studies completed for this project have determined that the Conditional Use poses very little threat to the underlying aquifer. No cumulative impacts are anticipated as none of the light -industrial uses occurring on or proposed for adjacent parcels involve the extraction of raw materials. 3) ADDITIONAL ANALYSIS: 1. 18.20.240(1)(b) Mineral extraction, mining, quarrying and reclamation Staff comment: Mining operations will be limited to the western 9.14 acres of the parcel, with the remainder of the site to remain undisturbed. This is a requirement under 18.20.254(2)(a) JCC, which states that "Any proposed mineral extraction which would create disturbed areas in excess of 10 gross acres shall require a Mineral Resource Land Overlay designation". 2. 18.30.170(1)(d) Storage of Soil, Sand, Salt and Other Erodible Materials. Staff comment: Construction and erosion control BMPs will be used during site clearing and development to prevent impacts to the surrounding area. With the exception of the north and west property boundaries abutting the airport and transit facility, the ten -foot earthen berm constructed around the perimeter of the project site will prevent material from being blown or washed onto adjacent parcels. 3. 8.70 Noise Control Staff comment: JCC 8.70 cites the MAXIMUM ENVIRONMENTAL NOISE STANDARDS described in WAC 173-60. As described in WAC 173-60-040, the maximum permissible environmental noise levels leaving an industrial site is restricted to 65 dBA before entering a commercial use, and 60 dBA for a residential property. A standard rock crusher produces around 85 dBA. The area in which operations will initially occur is within the existing ten -foot -deep excavation. This processing area is within the northern portion of the project area and is approximately 500 feet away from the nearest structure. The applicant states that the existing pit will reduce that by 10-15 dBA. The 10-foot-tall earthen berm will further reduce noise volumes. Forest's reduce sound by approximately 5 dBA per 100 feet. While the depth of the forested area will shrink as the pit expands, the additional depth should keep the noise volume within acceptable levels. The hours of operation will be 7a.m to 7p.m Monday through Friday, as specified in 18.20.240(2)(f) JCC. 18.15.405 Airport Overlays The subject parcel is within Airport Overlay 2. The proposed use is not included among the Prohibited uses listed in 18.15.430. The proposed use does not encourage the gathering of high concentrations of people. 18.15.445 Comment by the Port of Port Townsend The Port of Port Townsend received an email notifying of a SEPA Notice of Application on May 14, 2025. No comments were received. 18.15.450 — approval criterion — Conditional use permits Prior to approval of a conditional use permit for a use located within Airport Overlay II, the administrator and/or hearing examiner shall make the following finding: "the proposed use is compatible with ongoing flight operations conducted at the Jefferson County International Airport Essential Public Facility." [Ord.8-06-1] ZON2024-00012 12 Staff comment: The Port of Port Townsend did not comment on this proposal. Jefferson County's Uniform Development Code Administrator has determined that the proposed Conditional Use satisfies this requirement.

The conditional use permit information sheet is designed to help you provide all the information necessary to facilitate a timely and well- informed decision on your application. You will use the Master Land Use Permit Application Form for all Conditional Use applications. Conditional use approval may involve either a Type If or Type III review process under the JCC, depending on the specific type of use. No conditional use permit can be granted unless consistency with the performance standards of JCC 18.20, the development standards of JCC 18.30 , the procedural requirements of Article VIII, Chapter 18.40 JCC, and other applicable requirements of the JCC have been satisfied. Types of Conditional Uses Conditional uses are typed and identified in Table 3-1 of the JCC, or may be classified as such by the Administrator pursuant to Article II, Chapter 18.15 JCC. There are three broad types of conditional uses identified in the JCC. Conditional ["C"] Use: Proposed uses that require a discretionary approval process and a public hearing before the Hearing Examiner. Applications for uses listed as a "C" in Table 3-1 of the JCC are processed according to the procedures for Type III land use decision established in Article VIII, Chapter 18.40 JCC. Conditional Administrative ["C(a)"] Use: Proposed uses that require approval by the Administrator but do not require a public hearing. Applications for uses listed as an administrative conditional use permit (i.e., "C(a)") in Table 3-1 of the JCC are processed according to the procedures for Type II land use decisions established in Article VIII of Chapter 18.40 JCC. Conditional Discretionary ["C(d)] Use: Proposed uses that, at a minimum, require approval by the Administrator but that, at the discretion of the Administrator, may be referred to the Hearing Examiner for a public hearing and final decision. Applications for uses listed as discretionary conditional use permits (i.e., "C(d)") in Table 3-1 of the JCC are, at a minimum, processed according to the procedures for Type II land use decisions established in Article VIII of Chapter 18.40 JCC. However, pursuant to JCC 18.40.520, the Administrator may on a case -by -case basis refer a discretionary conditional use permit application to the Hearing Examiner to be processed according to the procedures for Type III land use decisions. In order to refer a "C(d)" application to the Hearing Examiner, the Administrator must make one of the following findings: • In the exclusive, discretionary judgment of the Administrator, the application involves potentially significant issues relating to location, design, configuration, and potential impacts to surrounding properties and the community that can be more appropriately considered and addressed through a public hearing before the Jefferson County Hearing Examiner; or In the exclusive, discretionary judgment of the Administrator, the application seeks approval of a use involving complex legal issues necessitating special expertise in the decision -maker. Process Step 1 — Pre -Application Conference: A pre -application conference is required for all conditional use permits. Conceptual plans, county requirements, future permit requirements, etc., and answers to related questions are discussed at the conference. Information provided by Department of Community Development staff helps the applicant to prepare a better application and potentially decreases code -related questions and time required for formal review. Step 2 — Determination of Completeness: Following submittal of your application, county staff will make a determination within 28 days as to whether your application is substantially complete. Step 3 — Formal Application Review and Decision: Following the determination of completeness, a final decision must be made by the county within 120 calendar days. The final decision may be made by either the Administrator (for all "C(a)" and certain "C(d)" uses) or the Hearing Examiner (for all "C" and certain "C(d)" uses) depending on the type of conditional use. Public hearings before Page 1 JC DCD Received 12/17/2024 the Hearing Examiner are required for all "C" uses and may be required for certain "C(d)" uses. In all conditional use permit cases the decision may be appealed. Approval Criteria Your conditional use application will be evaluated on the basis of the criteria listed in the relevant section of the Jefferson County Code (see JCC 18.40.530), and in some instances, inspection of the property. The county may approve or approve with modifications an application for a conditional use permit (i.e., uses listed in Table 3-1 as "C(a)," "C(d)" or "C") only if all of the following criteria are satisfied. • The conditional use is harmonious and appropriate in design, character and appearance with the existing or intended character and quality of development in the vicinity of the subject property and with the physical characteristics of the subject property; ■ The conditional use will be served by adequate infrastructure including roads, fire protection, water, wastewater disposal, and storm water control; • The conditional use will not be materially detrimental to uses or property in the vicinity of the subject parcel; • The conditional use will not introduce noise, smoke, dust, fumes, vibrations, odors, or other conditions or which unreasonably impact existing uses in the vicinity of the subject parcel; • The location, size, and height of buildings, structures, walls and fences, and screening vegetation for the conditional use will not unreasonably interfere with allowable development or use of neighboring properties; • The pedestrian and vehicular traffic associated with the conditional use will not be hazardous to existing and anticipated traffic in the vicinity of the subject parcel; • The conditional use complies with all other applicable criteria and standards of this Code and any other applicable local, state or federal law; and more specifically, conforms to the standards contained in 18.20 and 18.30 of this Code; • The proposed conditional use will not result in the siting of an incompatible use adjacent to an airport or airfield; • The conditional use will not cause significant adverse impacts on the human or natural environments that cannot be mitigated through conditions of approval; • The conditional use has merit and value for the community as a whole; The conditional use is consistent with all relevant goals and policies of the Jefferson County Comprehensive Plan; and • The public interest suffers no substantial detrimental effect. Consideration shall be given to the cumulative effect of similar actions in the area. In instances where all of the -above findings cannot be made, the application shall be denied. The County, in accordance with JCC 18.40.540, may impose additional conditions on a particular use if it is deemed necessary for the protection of the surrounding properties, the neighborhood, or the general welfare of the public. The county may add conditions which: • Increase requirements in the standards, criteria or policies established by the JCC; • Stipulate an exact location for the conditional use on the subject property as a means of minimizing hazards to life, limb, property damage, erosion, landslides or traffic; • Require structural features or equipment as a means of minimizing hazards to life, limb, property damage, erosion, landslides or traffic; or • Contain restrictions or provisions deemed necessary to establish parity with uses permitted in the same zone with respect to avoiding nuisance generating features in matters of noise, odors, air pollution, wastes, vibration, traffic and physical hazards. Approval of the conditional use is effective for three (3) years from the date of original approval. If a building permit has not been issued within the three (3) year period, the conditional use approval will expire. Minor modifications to a previously approved conditional use may be approved subject to the provisions of JCC 18.40.570.

No conditional use permit can be granted unless consistency with the performance standards of JCC 18.20, the development standards of JCC 18.30, the procedural requirements of JCC 18.40.280, and the approval criteria of JCC 18.40.530, and other applicable requirements of the UDC have been satisfied. Approval of the conditional use is effective for three (3) years from the date of original approval. If a building permit has not been issued within the three (3) year period, the conditional use approval will expire. The following questions will assist in the evaluation of the conditional use request: 1. Describe the requested conditional use. Sand and Gravel mining. 2. Explain how the conditional use is harmonious and appropriate in design, character and appearance with the existing or intended character and auality of development in the vicinitv and with the physical characteristics of the subject property. Mining is an allowed use within the current zoning. Site is next to an airport so it is less likely to disturb residents within the area. Site will maintain a small footprint and limited operations to minimize impacts to the surrounding area. 3. Describe the infrastructure including but not limited to roads, fire protection, water, wastewater disposal, and stormwater control which will serve the requested conditional use. Site will maintain setbacks, drainages and an infiltration pond. Proper BMP's will be employed to ensure minimal impacts to the surrounding environment. Site will have minimal equipment on -site for operations. Access road has already been established. 4. Describe the location, size, and height of buildings, structures, siona e, walls and fences, and screening vegetation for the use. There will be no permanent structures erected. All equipment on site will be temporary. Signs will be placed around the perimeter of the mining limits. A 50-ft vegetated setback will remain from the property boundary to help screen and minimize impacts to the surrounding parcels. 5. Describe any noise, smoke, dust, fumes, vibrations, odors, outdoor lights or other impacts will be generated by the conditional use. Normal construction dust and noise associated with material haul, equipment operation, and rock crushing. Dust emissions will be managed with a water truck when necessary. Site will operate with best management practices and follow an approved Site Management Plan. 6. Describe the pedestrian and vehicular traffic and parkina area associated with the conditional use. There will be no pedestrian access to the area. Traffic will only include employees to operate heavy equipment and dump trucks to haul away material. Site will operate on an as needed basis and will have minimal impacts to traffic. Page 3 JC DCD Received 12/17/2024 7 Will the proposed conditional use result in the siting of an inc om atible use adjacent of an airport or airfield? No 8. Are there any significant adverse impacts on the human and natural environments caused directly by the conditional use? If yes, can these impacts be mitigated? No. Vegetation within the mining limits will be cleared as needed and site will be reclaimed to forestry use. 9. Describe how granting the conditional use will not be materially detrimental to uses or property in the vicinity of the subject arcel. Granting the conditional use of the property will not impact the surrounding parcels negatively. Operations will run on an as needed basis, noise, and dust will be minimal. A water truck will help aid with dust when needed. Property sits next to Jefferson airport which produces higher noise volume then the site operations will. Due to operations only running on a per job basis, noise will be limited throughout the life of the site. 10. Describe how granting the conditional use will not be substantially detrimental to the public interest. The site is not in a heavily populated residential area. Site is bordered by land owned by the Port of Port Townsend on the north and east sides, and Jefferson county DOT to the West. The south end of the property borders 7 residential parcels with ample acreage and vegetation to help aid in screening the operations. 11. Does the conditional use have merit and value for the community as a whole? Yes, mining activities create jobs and capitalizes on the area's natural resources. 12. Describe how the conditional use complies with all other applicable criteria and standards of the Jefferson County Code (JCC) and any other applicable local, state or federal law; and more specifically, conforms to the standards contained in JCC 18.20 and JCC 18.30. Site will adhere to Jefferson County's strict standards regarding mining in a RR-10 zoned area and will follow an extensive mining and reclamation plan. 13. Describe how the conditional use is consistent with all relevant goals and policies of the Jefferson County Comprehensive Plan. Site will not disrupt the greater Jefferson County Comprehensive Plan as it is a temporary resource extraction and will be reclaimed to its zoned condition. Mining is a vital resource for the local economy and aids in the growth of a community.

SDR is required prior to development. The result of SDR is a description of the physical aspects and constraints of the site for the purpose of guiding development. While SDR will not vest a property to development regulations, it provides for a professional analysis of the site according to current development regulations. Jefferson County Department of Community Development (DCD) Planning staff has reviewed the property at 225 Four Corners Road, Port Townsend, parcel 001332016. This SDR reflects the conditions of the property at the date the review was completed. PROPERTY REVIEW: Current Use of Property: Forestry Description of Proposed Work: Sand and Gravelling Mining operations. Staff Comment: As per the land use Table in ]CC 18.15 a Conditional Use (C) permit will be required from DCD to permit a mining facility on the subject property. Permit History: Standalone Stormwater permit completed through ZON2019-000033. Water Service Area: Quimper Zoning: This parcel is zoned Rural Residential, one dwelling unit per ten acres (RR 1:10). This is a conforming lot and is 23.60 acres in size. Legal Lot of Record Status: This parcel qualifies for Jefferson County Code (KC) 18.12.050(1): "(1) All of the following standards apply to determine whether a lot is a legal lot of record: (a) The lot was legally created, or is a lot owned by an innocent purchaser for value who meets the requirements of JCC 18.12.100 and RCW 58.17.210; and (b) The lot of record qualifies under one of the following: (i) It is equivalent in size to the density of the zoning district in which it is located;" Abbreviated Legal Description: S33 T30N R1W TAX 51(LS TX 52 THRU 54,93) Full Legal Description: That real property as described as "Exhibit J" of the Quit Claim Deed recorded on April 28, 2014 under Auditor's File Number (AFN) 583402. Contact DCD if you would like to record your Legal Lot of Record Determination. Setbacks: According to the land use table in JCC 18.15.040(Table 3.1), mineral extraction activities fall under a Commercial Use. Therefore, the setback to all other residential properties is 35 feet. Additionally, the setback to all other industrial properties is 20 feet. If any easements exist, including an ingress/egress easement, there may be a 20-foot setback per Jefferson County Code (]CC) 18.30.050. Airport Overlay II: The Airport Overlay II includes areas that lie beneath the FAA - mandated traffic pattern for aircraft ascending or descending from the JCIA. As such, this area is subject to routine aircraft over -flights. It is acknowledged that areas lying outside the delineated Airport Overlay II zone may also be subject to aircraft over -flights. Jefferson County Environmental Public Health (JCEPH) Comments: Not reviewed Shoreline Master Program (Chapter 18.25 JCC): There is no shoreline environmental designation on this parcel. Critical Areas: Seismic Hazard, Special Aquifer Recharge Protection Areas (SARPA), Susceptible Aquifer Recharge Area (SUSC) Seismic Hazard: Seismic Hazard is mapped on the subject property. ]CC 18.22.530(11) states: (11) Seismic Hazard Development Standards. (a) Development activities or actions requiring a project permit occurring within 200 feet of a `high hazard" seismic hazard area may be allowed with an approved geotechnical report that confirms the site is suitable for the proposed development and addresses any fill or grading that has occurred on the subject parcel. (b) Development activities or actions requiring a project permit within a seismic hazard area shall be in accordance with ]CC Title 15. Because the Jefferson County GIS database does not label any seismic hazard as "High Seismic Hazard" no protection standards in JCC 18.22.530 have been identified for this project. Additional protection standards or reports may be identified through review of the Conditional Use Permit for mining operations on this parcel. Special Aquifer Recharge Protection Areas (SARPA) and Susceptible Aquifer Recharge Area (SUSC): SARPA and SUSC are both mapped on the subject property. As per JCC 18.22.330(6), mining practices within Critical Aquifer Recharge Areas must meet or exceed the development standards and Best Management Practices described in ]CC 18.30.170, as well as the performance standards in JCC -18.20.240. Requirements for this project specifically will be determined through the Conditional Use Permit. Required Reports: No reports are required at this time, but DCD may determine that reports are required during the review of the Conditional Use Permit. Stormwater permitting: Stormwater Best Management Practices (BMPs) shall be implemented as conditioned on any permit approvals and as required in the current edition of the Stormwater Management Manual for Western Washington. Jefferson County has adopted the most current edition of the manual produced by Washington State Department of Ecology. • A Stormwater Management Permit is required for grading of 500 cubic yards or more, land -disturbing activities of 7,000 square feet or more, or creation of 2,000 square feet or more of impervious surface. This approval may be obtained through a building permit or, if you wish to clear the property prior to building, you must obtain a separate stormwater management permit. This is required prior to clearing and grading for related development, such as septic system installation or road/driveway construction. • Stormwater Management Permits or Vegetation Removal Permits are required for any tree removal within a critical area or its buffer regardless of square footage cleared. • Impervious surface includes gravel surfaces. • Building permits must address stormwater. o A small project is any impervious surface under 2,000 square feet. You must meet minimum requirement #2 from the manual. o A medium project is any impervious surface from 2,000 to 4,999 square feet or 7,000 or more square feet of clearing. You must meet minimum requirements #1-#5, including on -site stormwater management. The building permit application should include a designed stormwater management system to address runoff from the roof and other hard surfaces. o A large project is any impervious surface from 5,000 square feet or greater. You must meet all minimum requirements. The building permit application should include a designed stormwater management system to address runoff from the roof and other hard surfaces. If your project meets the large project threshold, your parcel is five acres or larger, you are not within an Urban Growth Area, and full stormwater dispersion cannot be met, an engineered stormwater plan is required to ensure low -impact design standards are met. • If you plan on clearing the property and would be required by the state Department of Natural Resources (DNR) to submit a Forest Practices Application (FPA), you must work with our department first to obtain a Stormwater Management Permit with State Environmental Policy Act (SEPA) review, in association with a Class IV -General FPA, in order to avoid a 6-year Development Moratorium per the state Forest Practices Act. Jefferson County recommends you contact DNR for FPA requirements. Next Steps: 1. Apply for development permit(s). A Conditional Use Permit will be required for the proposed minipit. January 14, 2025 UDC Admisiistrator, Jefferson County DCD Date NOTICE TO APPLICANT: The purpose of the SDR is to provide owners and developers of land with a professional assessment of possible site development issues without first applying for permits. As this is a preliminary review of available GIS mapping data and nontechnical information supplied by the applicant, it is NOT a guarantee that development can occur in the manner described. However, it is a valuable tool to allow applicants to plan out the development process in advance. Here are three key disclaimers: • Site Development Review DOES NOT VEST applicants to a particular set of regulations; that can only be accomplished in the manner set out in JCC 18.40.320, which in many cases requires Fling of a building permit application. • Completion of this review does not guarantee future approval for an onsite septic system. An applicant must apply for and complete all required permitting pursuant to chapter 8.15 JCC and WAC 246-272A. Use of older septic systems is not guaranteed. • The adequacy of a potable water supply cannot be assessed until the time of building permit application. Proposals necessitating a determination of adequate potable water supply must meet all county and state requirements in effect at the time of application. All parcels connecting to County roads or State highways require an approved access. 4 NORTHWEST MINING SOLUTIONS Four Corners Pit Narrative Date: July 1311,2024 Permit Holder: Bruce Seton Jr, Seton Construction, Inc Site: Four Corners Sand & Gravel Pit 225 Four Corners Rd, Port Townsend, WA 98368 Permit #: New Site Parcel ID (s): 001332016 Objective: LOG ITEM Page Of � To apply for a Conditional Use Permit to allow mining on parcel 001332016 in Jefferson County. The site would be known as Four Corners Sand & Gravel Pit. The approval would allow Seton Construction, Inc to extract all available resources down 30-ft to 110-ft msl. Site disturbance would be limited to 9.14 acres with a 50-ft setback from the property line. This site is expected to yield approximately 333,000 CY with this plan. Mining and reclamation will occur in 2 phases. Reclamation will occur as mining progresses. Once a Conditional Use Permit is obtained from Jefferson County, Seton Construction will seek a Surface Mine and Reclamation Permit with the Washington State Department of Natural Resources, and a Sand & Gravel General Permit from the Washington State Department of Ecology. Legal Description: SE'/4 of NW'/4 of Section 33, Township 30N, Range 01W Zoning: RR-10 Rural Residential Hours of Operation: 7:00am-7:00pm Monday -Friday per JCC 18.20.240 (2)(fl Site History: Forested, Unoccupied Current Site Conditions: Forested, Unoccupied NORTHWEST MINING SOLUTIONS, LLC 1 Proposed Plan: 9.14 acres of the site will be mined for sand and gravel resources and immediately reclaimed to forestry. Phasing Plan: Site has two phases that will be mined in a progressive manner. As mining is completed in a section, reclamation will immediately follow. This allows for mining to seamlessly progress. Mining may occur in both phases concurrently as long as reclamation progresses with it. Setbacks: 50-ft from property line Groundwater: Site will remain well above groundwater at all times. No mining will occur within the groundwater. Slope Design: Mining will progress with 2:1 slopes at a max depth of 30-ft. Excavation: Material on -site is mainly sand and gravel deposits. Slopes will be excavated using heavy equipment. Excavators, dozers, and or loaders will be used to extract the material from the ground. The material will then be conveyed via truck or loader to the processing area for processing. Processing area will include stockpiles, overburden, waste rock, and topsoil. Stockpiles will be sold or remain for reclamation purposes. Critical Areas: Site is in a Critical Aquifer Recharge Area and Soil Seismic Area. A Geologic assessment has been conducted on -site to address these concerns. See attached study for details. Signage: No trespassing mining limits signs will be placed around the perimeter of the permit boundary. The site entrance will have a safety and no trespassing sign with site contacts listed on it. Air Quality: Extraction and processing will be conducted to comply with state air quality standards and will comply with particulate emission restrictions. If needed the haul road will be sprayed to control dust with a water truck. Topsoil: Needed topsoil will be stored within the current mining area for reclamation purposes. Approximately 14,800 CY of topsoil will be required for reclamation purposes. Topsoil will be used to reclaim each phase's final slopes and mine floor. See attached Revegetation Plans within the Reclamation Plans for further details. Stormwater: All slopes and ditches will be graded to direct stormwater to the infiltration pond. Channels will be rock and grass lined to allow for infiltration and to prevent erosion. Drainages will maintain a minimum 2% slope to direct water to the on -site infiltration pond in the floor of the pit. Pond will vary in size and grow as needed and as mining progresses through phasing. See attached stormwater calculations and stormwater details in reclamation plans for further information. NORTHWEST MINING SOLUTIONS, LLC Berms: Berms half the height of the tires of the haul trucks will be along the outer edge of the haul road and at the toe of the slope. This will help divert drainage, and act as a safety measure. A 10-ft high earthen berm will be constructed around the perimeter of the active pit to help reduce noise to the surrounding area. Archeology: Should ground disturbing or other activities related to the development result in the inadvertent discovery of cultural or archaeological materials, work shall be stopped in the immediate area and the Washington State Department of Archaeology and Historic Preservation (DAHP) will be contacted. Work shall remain suspended until the findings are assessed, and appropriate consultation is conducted. Should human remains be inadvertently discovered, as dictated by Washington State RCW 27.44.055, work shall be immediately halted in the area and local law enforcement will be contacted. Removal of Vegetation: Site will be stripped in phases. As each section is mined all topsoil will be stripped and stockpiled for reclamation purposes. Trees will be logged and debris will be processed and stockpiled for reclamation purposes. Topsoil will be stored on -site, it will be seeded and managed with proper BMP's. Topsoil will be used to reclaim each phase's final slopes and mine floor. See attached Revegetation Plans within the Reclamation Plans for further details. Erosion Control: Slopes will be permanently hydroseeded for erosion control. Grass and rock lined channels will help direct water to an on -site infiltration pond. Proper BMP's will be utilized around the site to help control water runoff. Reclamation Topography and Mine Floor: The site will be mined in two phases to a final mine floor elevation of 110-ft msl. Slopes will be mined at 2H:1 V with a max depth of 30-ft. Mining will occur in each phase and reclamation will immediately follow. Once slopes are finalized at a 2H:1 V slope, the slope will be revegetated. Once all phases have been mined, the mine floor will be revegetated and returned to forestry use. See Reclamation Plans for further details. Final Drainage Configuration: All slopes and ditches will be graded to direct stormwater to the infiltration pond. A single infiltration pond will be left on -site as a permanent feature. It is expected that as vegetation grows the pond will naturally become seasonal. Site Cleanup and Preparation for Revegetation: As site approaches reclamation the site will be cleaned up and prepared to have all debris and equipment removed from site. All Debris, vehicles, and storage containers will be removed from the site prior to the completion of reclamation. Revegetation: NORTHWEST MINING SOLUTIONS, LLC 3 Site will follow the approved Revegetation Plan within the Reclamation Plans. Revegetation will occur as mining progresses and slopes have been backfilled. When permanent slopes have been created, slopes will be hydroseeded and revegetated according to the Revegetation Plans.
