(a) Mineral Resource Lands Overlay District (MRL). The mineral resource land district is to provide for the conservation of mineral lands of long-term commercial significance (Article VI-C of this chapter). The intent of this district is to aid in sustaining and enhancing mineral extraction and processing activities of long-term commercial significance by protecting designated lands from incompatible development and to allow for the continued contribution of mineral lands to the Jefferson County economy. [Ord. 8-06 § 1] 18.15.170 Designation procedures. A mineral resource land (MRL) overlay district may be applied based upon the following criteria, only upon acceptance by the county of a complete application from a property owner and upon approval of a redesignation in accordance with Chapter 18.45 JCC and processed as a Comprehensive Plan amendment. MRLs of long-term commercial significance are those lands from which the commercial extraction of minerals (sand, gravel, rock, and other valuable aggregate or metallic substances) can be anticipated within 20 years and which are characterized by all of the following: (1) Have a known or potential extractable resource in commercial quantities verified by submittal of a geologic and economic report prepared by a qualified professional; (2) The parcel is a minimum of 10 acres in size; (3) The subject property is surrounded by parcels no smaller than five acres in size on 100 percent of its perimeter; (4) The current or future land use designation will not exceed a residential density of one dwelling unit per five acres; (5) Are not within any shoreline designation, urban growth area or rural village center or within one- half mile of any established or potential urban growth area or rural village center boundary, as shown on the official maps of the Comprehensive Plan; and (6) Are not within a regulated wetland or fish and wildlife habitat area pursuant to Chapter 18.22 JCC. [Ord. 14-18 § 4 (Exh. B); Ord. 8-06 § 1] 18.15.180 Nuisance and disclosure provisions. (1) Nuisance. The following shall not be considered a nuisance: mineral resource extraction and processing activities, operations (except between 7:00 p.m. and 7:00 a.m. and on weekends), facilities or appurtenances thereof, conducted or maintained for commercial mineral resource extraction and processing purposes on land designated as mineral resource land (MRL), regardless of past or future changes in the surrounding area land use or land use designation. Draft Work Product Pre-Application Meeting PRE2021-000 Comprehensive Plan Amendment – Mineral Resource Land Overlay (2) Disclosure. The disclosure statement in subsection (2)(b) of this section shall be used under the following circumstances and in the following manner: (a) Approval of any land division, land use, building, or development of lands adjacent to or within 500 feet of lands designated as mineral resource land (MRL) shall be conditioned on the execution by the applicant of a statement of acknowledgment containing the disclosure statement on forms provided by the department of community development. However, if a disclosure conforming to the provisions of this section has been provided for a prior permit, subsequent disclosures shall not be required. (b) The required disclosure statement is as follows: If your real property is within five hundred (500) feet of real property within an area designated as Mineral Resource Land (MRL), you may be subject to inconveniences or discomforts arising from such operations, including but not limited to noise, tree removal, odors, fumes, dust, smoke, the operation of machinery, and the storage and disposal of aggregate products. One or more of the inconveniences described may occur as a result of extraction and processing operations which are in conformance with existing laws and regulations. Jefferson County has determined that the use of certain real properties for mineral resource extraction and processing activities is necessary to ensure resource availability in the County. The County will not consider to be a nuisance those inconveniences or discomforts arising from extraction and proc essing operations, if such operations are consistent with commonly accepted best management practices and comply with local, state, and federal laws. [Ord. 8-06 § 1] 18.15.155 Established. Overlay districts provide regulations in addition to those of other sections in this code for certain land areas and for uses which warrant specific recognition and management. See the official maps for the location of the overlay districts. Except as otherwise provided in this Article VI, the provisions of an overlay district shall prevail over any conflicting provisions of this code for the duration of the overlay district, subject to RCW Title 36. All other provisions of this code shall remain in full force and effect within the overlay district. 18.20.240 Mineral extraction, mining, quarrying and reclamation.

[Ord. 14-18 § 4 (Exh. B); Ord. 8-06 § 1] 18.30.170 Mining, quarrying and asphalt/concrete batch plant best management practices in critical aquifer recharge areas. The following shall be considered minimum development standards necessary only for mineral extraction, quarrying and asphalt/concrete batch plant operations located in susceptible aquifer recharge areas or special aquifer recharge protection areas as defined in Article VI-E of Chapter 18.15 JCC. See also the performance and use-specific standards requirements of JCC 18.20.070 (Asphalt and Concrete Batch Plants) and JCC 18.20.240 (Mineral Extraction, Mining, Quarrying and Reclamation) for general mining, quarrying and asphalt/concrete batch plant Draft Work Product Pre-Application Meeting PRE2021-000 Comprehensive Plan Amendment – Mineral Resource Land Overlay operations. Asphalt batch plants are prohibited in special aquifer recharge protection areas (JCC 18.15.250(1)(b)). (1) Best Management Practices. (a) Concrete and Asphalt Production at Stationary Sites. This activity applies to any activity that mixes raw materials on-site to produce or enhance concrete or asphalt. It also applies to subsequent activities such as pouring concrete structures, and making other concrete and asphalt products. Mishandling of raw materials on concrete production can introduce suspended solids and heavy metals to stormwater runoff and cause pH increases in receiving waters. In addition, stormwater pollution can result from washing of waste concrete from trucks, forms, wheelbarrows, buckets, and other equipment in the work area. The loose chunks of aggregate resulting from washing of equipment can easily reach storm drains, either in the wash water itself or in stormwater runoff. Asphalt emulsion and chunks of aggregate can easily wash off of equipment used in mixing and production in a similar manner as concrete. Mobile concrete pouring and asphalt application are covered under a separate activity in these administrative rules. Concrete production at mining sites is also covered by this activity. (i) Minimum Requirements. The following BMPs, or equivalent measures, methods, or practices, are required if you are engaged in concrete and asphalt mixing and production: (A) Discharge all process water from production, pouring, and equipment cleaning activities to a sump, process water treatment or recycling system, or sanitary sewer system. (B) Contain the production and pouring area to prevent stormwater from entering the area and carrying pollutants away. (C) Routine maintenance. (I) Sweep the production and pouring areas weekly, if it is paved, to collect loose chunks of aggregate and raw material particles for recycling or proper disposal. (II) Do not hose down area to a storm drain. (ii) Additional BMPs. The following BMPs, intended to provide improved pollution control, may be required of an applicant by the administrator in a manner consistent with Chapter 18.40 JCC: (A) Use an oil control device in the catch basins to treat stormwater runoff. (B) Cover the production area with provisions for prevention of stormwater run on. (C) Pave the mixing, production and/or pouring area(s) with a slope to a central collection area. For concrete production and pouring activities, a sump drain should not be provided because it would be quickly clogged with hardened concrete. It may not be wise to segregate the mixing and pouring area from the curing area because wastewater from curing applications could be collected by a drain. By sloping the Draft Work Product Pre-Application Meeting PRE2021-000 Comprehensive Plan Amendment – Mineral Resource Land Overlay pavement to a central location, loose chunks of concrete or asphalt aggregate can be collected more easily and recycled or disposed of properly. (b) Storage of Liquid Materials in Stationary Tanks. This section applies to any activity that stores any type of liquid chemicals, waste oils, solvents, or petroleum products in above- ground storage tanks. Leaking tanks on these sites can contribute toxic compounds, oils and greases, heavy metals, abnormal pH, and nutrients to stormwater runoff. In addition, spills may occur during liquid transfer operations to and from the tanks. This activity does not apply to underground storage tanks or to businesses permitted by the Washington State Department of Ecology to treat, store, or dispose of dangerous wastes. Storage of reactive, combustible, or flammable liquids must comply with the fire code requirements and may need to comply with the Washington State Department of Ecology regulations. (i) Minimum Requirements. The following BMPs, or equivalent measures, methods or practices are required if you are engaged in storage of liquid materials in stationary tanks: (A) Store and contain liquid materials in such a manner that if the tank is ruptured, the contents will not discharge, flow or be washed into the storm drainage system, surface waters, or groundwater. OR (B) If the liquid is oil, gas or other material that separates from and floats on water, install a spill control device (such as a tee section) in the catch basins that collect runoff from the storage tank area. (C) Routine Maintenance. (I) Place drip pans or absorbent materials beneath all mounted taps, and at all potential drip and spill locations during filling and unloading of tanks. Any collected liquids or soiled absorbent materials must be reused/recycled or properly disposed. (II) Store and maintain appropriate spill cleanup materials in a location known to all near the tank storage area; and ensure that employees are familiar with the site’s spill control plan and/or proper spill cleanup procedures. (III) Sweep and clean the storage area monthly if it is paved; do not hose down the area to a storm drain. (IV) Check tanks (and any containment sumps) daily for leaks and spills. Replace tanks that are leaking, corroded, or otherwise deteriorating with tanks in good condition. Collect all spilled liquids and properly dispose of them. (c) Storage of Any Liquid Material in Portable Containers. This section applies to any activity that stores any type of liquid chemicals, waste oils, solvents or petroleum products in portable containers (such as drums). This activity covers permanent storage as well as temporary Draft Work Product Pre-Application Meeting PRE2021-000 Comprehensive Plan Amendment – Mineral Resource Land Overlay storage areas at temporary sites. Spills and drips of these liquids, or overtopping of storage containers, can contribute toxic compounds, oils and greases, heavy metals, abnormal pH, and nutrients to stormwater runoff. This section does not apply to businesses that are permitted by the Washington State Department of Ecology to treat, store, or dispose of dangerous waste. Storage of reactive, combustible, or flammable liquids must comply with the Washington State Department of Ecology regulations. (i) Minimum Requirements. The following BMPs, or equivalent measures, methods, or practices, are required if you are engaged in storage of liquid materials in portable containers: (A) Place tight-fitting lids on all containers. (B) Enclose or cover the containers where they are stored. The local fire district must be consulted for limitations on clearance of roof covers over containers used to store flammable materials. (C) Raise the containers off the ground by use of pallet or similar method, with provisions for spill control. OR (D) Contain the material in such a manner that if the container leaks or spills, the contents will not discharge, flow, or be washed into the storm drainage system, surface waters, or groundwater. (E) Place drip pans or absorbent materials beneath all mounted container taps, and all potential drip and spill locations during filling and unloading of containers. Any collected liquids or soiled absorbent materials must be reused/recycled or properly disposed. (F) Routine Maintenance. (I) Store and maintain appropriate spill cleanup materials in a location that is known to all employees near the tank storage areas, and ensure that employees are familiar with the site’s spill control plan and/or proper spill cleanup procedures. (II) Sweep and clean storage area monthly if it is paved; do not hose down the area to a storm drain. (III) Check containers (and any containment sumps) daily for leaks and spills. Replace containers that are leaking, corroded, or otherwise deteriorating with ones in good condition. If the liquid chemicals are corrosive, containers made of compatible materials must be used instead of metal drums. New or secondary containers must be labeled with the product name and hazards. Draft Work Product Pre-Application Meeting PRE2021-000 Comprehensive Plan Amendment – Mineral Resource Land Overlay (IV) Collect all spilled liquids and properly dispose of them. (d) Storage of Soil, Sand, Salt and Other Erodible Materials. This section applies to stockpiling erodible raw materials such as soil, sawdust, gravel, sand and road de-icing salts. It covers permanent sites as well as temporary construction sites and other temporary locations. Raw material stockpiles can easily erode due to wind or precipitation and contribute suspended solids, nutrients, heavy metals, and abnormal pH to stormwater runoff. (i) Minimum Requirements. The following BMPs, or equivalent measures, methods, or practices, are required if you are engaged in the storage or stockpiling of erodible material on a normal or temporary basis: (A) Site and contain the stockpiles of raw material in such a manner so as to prevent off-site impacts of surface water runoff, erosion, and sedimentation. (B) Routine Maintenance. (I) Sweep paved storage areas monthly for collection and disposal of loose solid materials; do not hose down the area to a storm drain or conveyance ditch. (II) Stock cleanup materials, such as brooms, dust pans, and vacuum sweepers (if desired) near the storage unit. (ii) Additional BMPs. The following BMPs, intended to provide improved pollution control, may be required of an applicant by the administrator in a manner consistent with Chapter 18.40 JCC: (A) A catch basin insert, configured for sediment removal, may remove some of the pollutants in runoff from this activity. (Catch basin inserts require frequent maintenance to be effective. Carefully consider this when making your decision.) (e) Engine Repair and Maintenance. This activity applies to operations that conduct engine repair and maintenance in vehicles and other equipment. It also applies to mobile vehicle maintenance operations, such as at construction sites. This common activity can lead to immediate stormwater contamination if it is not done in a controlled manner. This activity can contaminate stormwater with toxic hydrocarbons, other toxic organic compounds, oils and greases, abnormal pH, and heavy metals. Related vehicle maintenance activities are covered under the following activity headings in these administrative rules: “Painting, Finishing, and Coating of Vehicles, Products and Equipment,” “Vehicle Washing and Stream Cleaning,” “Fueling Operations, and Vehicle and Equipment Parking and Storage.” (i) Minimum Requirements. The following BMPs, or equivalent measures, methods, or practices, are required if you are engaged in engine repair and maintenance: (A) If temporary work is being conducted outside, use tarp, ground cloth, or drip pans beneath the vehicle or equipment to capture all spills and drips. The collected drips and spills must be disposed of, reused, or recycled properly. Draft Work Product Pre-Application Meeting PRE2021-000 Comprehensive Plan Amendment – Mineral Resource Land Overlay (B) If the work is done on a regular basis at a stationary business location, move the activity indoors. (C) Routine Maintenance. (I) Employees must be educated on proper handling and disposal of engine fluids. (II) Store and maintain appropriate spill clean up materials in a location known to all; and ensure that employees are familiar with the site’s spill control plan and/or proper spill cleanup procedures (reusable cloth rags can be used to clean up small drips and spills instead of disposables; these can be washed by a permitted industrial laundry; do not clean them at home or a coin-operated laundry business). (III) Sweep the maintenance area weekly, if it is not paved, to collect loose particles, and wipe up all spills with rags and other absorbent material immediately; do not hose down the area to a storm drain. (ii) Additional BMPs. The following BMPs, intended to provide improved pollution control, may be required of an applicant by the administrator in a manner consistent with Chapter 18.40 JCC: (A) Absorbent material such as pillows or brooms can be used around storm drains or in catch basins to absorb oil and other substances. A qualified disposal contractor must pick up used absorbent material containing oil or other engine fluids. (B) A catch basin insert, configured for oil removal, may remove some of the pollutants in runoff from this activity. (Catch basin inserts require frequent maintenance to be effective. Carefully consider this when making your decisions.) (f) Vehicle Washing and Steam Cleaning. This activity applies to operations that receive shipments of bulk liquid materials by truck or rail and transfer those liquids into storage tanks or containers or handle the truck or rail loading of liquid materials from tanks. Spills and drips of these liquids can potentially contribute toxic organic compounds, oils and greases, nutrients, heavy metals, and abnormal pH to stormwater runoff. (i) Minimum Requirements. The following BMPs, or equivalent measures, methods, or practices, are required if you are engaged in vehicle washing and steam cleaning: (A) It is allowable to rinse down the body of a vehicle, including the bed of a truck, with just water without doing any washwater control BMPs. (B) If you wash (with mild detergents) on an area that infiltrates water, such as gravel, grass or loose soil, it is acceptable to let the washwater infiltrate as long as you only wash the body of the vehicles. Draft Work Product Pre-Application Meeting PRE2021-000 Comprehensive Plan Amendment – Mineral Resource Land Overlay (C) However, if you wash on a paved area and use detergents or other cleaners, or if you wash/rinse the engine compartment or the underside of the vehicles, you must do one of the following options: (I) Designate and pave wash area to wash all vehicles in. Discharge wash water from vehicle cleaning operations to a sanitary sewer, holding tank, or process treatment system or process through an enclosed recycling system. The local sewer authority may have limits on the types and amounts of pollutants, such as oil and heavy metals that can be discharged to a sanitary sewer. Absolutely no untreated wash water can enter storm drains. OR (II) Designate and pave wash area to wash all vehicles in. Use a storm drain cover or other effective method of preventing all wash and rinse water from entering a storm drain or other drainage system feature. All runoff from the activity must be collected from proper disposal to a sanitary sewer. A wet vacuum or pump can be used for this. There are several products commercially available that enable collection of runoff. This requirement also applies to mobile vehicle washing services. OR (III) Take the vehicles to a commercial car wash or use a mobile washing service that complies with either of the previous options. (D) Designated wash area must be well-marked with signs indicated where and how washing must be done. (E) Oil changes and other engine maintenance cannot be conducted in the designated washing area. (g) Optional BMPs. The BMPs listed below are measures that should be considered at all times for improving pollution control. While these BMPs are not mandatory, applicants are encouraged to incorporate them in their plan for implementing BMPs, and the administrator may, in a manner that is consistent with Chapter 18.40 JCC, require that an applicant implement one, several or all of the BMPs listed in this section. Implementing one, some or all of these BMPs may reduce or eliminate the need to implement other more complex or costly BMPs. (i) Locate activities as far as possible from surface drainage paths. Locating activities on high ground, far from drainage paths, ditches, gutters and storm drains allows more time to recognize spills and act to prevent water contamination. (ii) Avoid the activity or reduce its occurrence. Often an alternative production process or material application process can be used to substitute for another, more polluting, process. Ideally, a polluting activity can be avoided altogether, or its frequency of occurrence reduced. An example is washing vehicles less often or taking vehicles to commercial car washes or detail shops rather than washing on-site. Draft Work Product Pre-Application Meeting PRE2021-000 Comprehensive Plan Amendment – Mineral Resource Land Overlay (iii) Use less material. Improper disposal of excess material or increased application of materials simply because excess is available can cause pollution. Purchase only the amount of material that will be needed for foreseeable use. In most cases you will see cost savings in both purchasing and disposal. (iv) Use the least toxic materials available. All applications of solid and liquid materials should use the least toxic products and raw materials available, whether in production; cleaning; pesticide applications; or other uses. (v) Create and/or maintain vegetated areas near activity location. Grass and types of vegetation can filter out many pollutants in stormwater runoff. Vegetated areas should be maintained around areas where polluting activities occur, especially down slope of activity areas. Routine maintenance will keep vegetated areas healthy and capable of filtering pollutants. (vi) Recycle as much as possible. Recycling is always preferable to disposal of unwanted materials. Leftover paints, finishes, cleaning materials, building materials, etc., may be used by someone else, so don’t throw them away. Contact a neighbor, friend, school, church, community group, theater group, etc., to see if your leftover materials can be used. Many empty containers and other common items are recyclable. Contact the Jefferson County Recycling Center for recycling options. (vii) Educate others about stormwater pollution prevention. Educate your employees, business associates, contractors, family, and friends about stormwater pollution control. Encourage others to find solutions to stormwater pollution problems, and to continue learning about pollution control techniques. (viii) Implement treatment BMPs. Treatment BMPs are used to remove pollutants from stormwater before being discharged from a site. These include oil separators and other catch basin inserts that control pollutants in the piped system and as well as numerous biological systems such as a biofiltration swales, infiltration, and constructed wetlands. These BMPs may be a preferred option in certain circumstances. (2) Best Management Practices (BMP) Report Criteria. The following criteria shall apply when preparing a best management practices (BMP) report: (a) The report shall be prepared by, or done under the direction of or designed by, a qualified person with demonstrated expertise in the industry or field as demonstrated by a statement of qualifications. (b) The report will identify appropriate BMPs and how they will be employed to prevent degradation of groundwater. Examples of BMPs are found in subsection (1) of this section. All necessary technical data, drawings, calculations, and other information to describe application of the BMPs must be supplied. (c) The report shall identify how the applicant will satisfy the requirements of the Dangerous Waste Regulations, Chapter 173-303 WAC, in the event that hazardous material is released into the ground or groundwater. Draft Work Product Pre-Application Meeting PRE2021-000 Comprehensive Plan Amendment – Mineral Resource Land Overlay (d) The report shall be reviewed by the department of community development or a consultant hired by the county, at the applicant’s expense, for this review. The county may consult with the Jefferson County health department, State of Washington Departments of Health or Ecology, independent reviewer, or any parties as it sees fit. [Ord. 8-06 § 1]
