(1) Purpose. The purpose of this chapter is to establish provisions to set criteria associated with the development and redevelopment of land to achieve the goals and policies of the Jefferson County Comprehensive Plan. This chapter is intended to accomplish the following purposes:

(a) Facilitate the orderly development of properly designed and constructed public and private roadways so as to provide a safe, durable and efficient integrated roadway system;

(b) Protect public rights-of-way, natural resources, and open space from degradation due to poor development practices;

(c) Protect the public interest in management of surface water drainage and related functions of drainage basins, watercourses, and shoreline areas; and

(d) Fulfill the objectives of the comprehensive planning policies of Jefferson County in promoting the health, safety, and welfare of the public.

(2) Applicability. The development standards of this chapter are designed to effect the goals and policies of the Comprehensive Plan, and apply to all development and land use activities subject to this code and within all land use districts except as may be specified below. [Ord. 8-06 § 1]

18.30.020 General development standards.

The development standards of this chapter shall apply within each land use district and shall be minimum standards that apply uniformly to each class or kind of structure or land, except as hereinafter provided:

(1) No building, structure or part thereof shall hereafter be erected, constructed, reconstructed, moved or structurally altered unless in conformity with all of the regulations specified in this chapter for the land use district in which it is located;

(2) No building or structure shall encroach on any public right-of-way; no building or structure shall encroach on any private easement or right-of-way unless written permission is obtained from the easement grantee or right-of-way owner;

(3) No part of a yard, or other open space, or off-street parking or loading space required about or in connection with any building for the purpose of complying with this chapter, shall be included as part of a yard, open space or off-street parking or loading space similarly required for any other building or structure;

(4) Except as may be specifically provided elsewhere in this code, only one dwelling unit and one accessory dwelling unit per lot is allowed in those districts that permit residential uses; and

(5) All land use activities shall be served by appropriate transportation facilities. Transportation facilities shall be adequate to meet the level of service standards adopted in the Jefferson County Comprehensive Plan and the appropriate design standards referenced in JCC 18.30.080(1)(a). If transportation facilities would become inadequate, the applicant shall be required to provide necessary improvements and/or implement alternative measures such as transportation demand management (TDM), project phasing, or other measures acceptable to Jefferson County that will maintain the adopted level of service standards and meet design standards. If transportation facilities are not adequate, Jefferson County shall not approve the proposed development. Transportation facilities shall be deemed adequate if necessary improvements are planned and designated funding is secured in the Jefferson County Six-Year Transportation Improvement Program. [Ord. 4-07 § 2; Ord. 8-06 § 1]

18.30.030 Water supplies.

When the development or redevelopment of land requires the availability of a supply of potable water as determined by the administrator, potable water shall be delivered by a means approved by the Washington Department of Health and/or Jefferson County public health.

(1) All development must conform to the requirements of Jefferson County public health and the Jefferson County coordinated water system plan regarding the availability and provision of water.

(2) Water supply facilities shall be adequate to provide potable water from a public or community water supply source and shall be constructed in conformity to standards of the jurisdictional governmental authority, unless Jefferson County public health approves the use of individual, on-site water supply wells.

(3) Water sources and facilities adequate for fire protection purposes shall be provided in all developments to the satisfaction of the Jefferson County fire marshal. Fire flow shall be determined in accordance with the provisions of JCC Title 15, as amended. [Ord. 14-18 § 4 (Exh. B); Ord. 8-06 § 1]

18.30.040 Sewage disposal.

(1) All development shall be provided with an individual, on-site septic system and drainfield approved by Jefferson County public health in compliance with Chapter 8.15 JCC, unless Jefferson County public health determines that public sewer is available which would then require connection to the approved public sewer.

(2) Design and construction standards for on-site sewage disposal shall conform to the requirements of Jefferson County public health or the agency having regulatory responsibility for the system.

(3) Large on-site sewage systems (LOSS) and community drainfields are not considered a sanitary sewer system as applied under the Growth Management Act. Jefferson County considers these systems a rural governmental service.

(4) New construction of a sanitary sewer system, extension, or connection to a sanitary sewer system located outside of an urban growth area, may only occur if:

(a) The new sanitary sewer system, extension, or connection is a necessary response to protect basic public health, safety, and the environment; the sewer is financially supportable at rural densities; and the sewer, extension, or connection does not permit urban development;

(b) The new sanitary sewer system, extension, or connection is necessary to support a limited area of more intensive rural development (LAMIRD); the sewer is needed to mitigate a threat to the public health, welfare, or to protect an area of environmental sensitivity caused by existing development; and the sewer is limited to those properties or facilities needed to mitigate the threat to the public health, welfare, or to protect an area of environmental sensitivity;

(c) The new sanitary sewer system, extension, or connection is necessary to provide service to an essential public facility if no practicable alternative exists to site the essential public facility in an urban growth area; or

(d) The new sanitary sewer system, extension, or connection supports schools sited in a rural area that serves students from a rural area and an urban area, when consistent with the Jefferson County Comprehensive Plan, RCW 36.70A.213, and the following requirements:

(i) The applicable school district has adopted a policy addressing the school service area, facility needs, and educational program requirements;

(ii) The applicable school district has made a finding, with the concurrence of the county legislative authority and the legislative authorities of any affected cities, that the proposed site is suitable to site the school and any associated recreational facilities that the applicable district has determined cannot reasonably be collocated on an existing school site, taking into consideration the extent to which vacant or developable land within an urban growth area meets those requirements;

(iii) The county and affected cities agree to the extension of sewer to serve the school sited in a rural area that serves urban and rural students at the time of concurrence of subsection (4)(d)(ii) of this section;

(iv) Any impacts associated with the siting of the school are mitigated as required by the State Environmental Policy Act, Chapter 43.21C RCW; and

(v) Any extension of the sewer beyond the urban growth area is subject to the following:

(A) Must only serve the applicable school and the costs of the extension must be borne by the applicable school district based on a reasonable nexus to the impacts of the school.

(B) Any exception from this subsection (4)(d)(v), when consistent with RCW 36.70A.110(4), shall allow the sewer to serve a property or properties in addition to the school if the property owner so requests; provided, that the county and affected cities agree with the request; and provided, that the property is located no further from the sewer than the distance that, if the property were within the urban growth area, the property would be required to connect to the sewer.

(C) If a property owner connects to the sewer under subsection (4)(d)(v)(B) of this section, the school district may, for a period of time not to exceed 20 years, require reimbursement from a requesting property owner for a proportional share of the construction costs incurred by the school district for the extension of the sewer. [Ord. 1-21 § 3 (Appx. 2); Ord. 14-18 § 4 (Exh. B); Ord. 8-06 § 1]

18.30.050 Density, dimension, and open space standards.

(1) Purpose. This section establishes: (a) density requirements; (b) bulk, area, and dimensional standards; and (c) specific rules for all uses. These standards and rules are intended to provide flexibility in project design and to maintain privacy between adjacent uses.

(2) Development Standards. This section and Table 6-1 contain general density, intensity, and dimensional standards for the various land use districts. Limitations specific to a particular district are also specified.

(3) Measurement Methods. The following methods will be used to determine compliance with this chapter:

(a) The “maximum density” for a parcel is calculated by dividing the parcel area by the total number of residential dwelling units allowed according to the density designation. Only whole density units may be used.

(b) “Parcel area” or “lot area” is the total horizontal land area contained within the boundaries of a parcel.

(c) If a development proposal depends on two or more lots, parcels or combinations thereof to be considered as a site for purposes of complying with the provisions of this title or any other provisions of the Jefferson County Code, DCD may require the applicant to record a covenant to the benefit of the county that requires retention of the lots under common ownership and control for the duration that the use is maintained on the site.

(d) Setbacks from roads shall be measured from the edge of the road right-of-way. Side and rear setbacks are measured from the edge of the property in the same manner as road setbacks.

(e) “Impervious surface” is measured by calculating the horizontal land area of all surface areas that create a barrier to or retard the entry of water into the soil in comparison with natural conditions prior to development. Open, uncovered retention/detention facilities shall not be considered as impervious surfaces. See also JCC 18.30.070 for storm drainage standards.

(f) The height of buildings and structures shall be calculated by the vertical distance from grade plane to the average height of the highest roof surface. Story height is calculated by the vertical distance from the top to top of two successive tiers of beams or finished floor surfaces; and, for the topmost story, from the top of the floor finish to the top of the ceiling joist or, where there is not a ceiling, to the top of the roof rafters (cf. International Building Code).

(4) Density Exemptions. In land use districts with minimum density requirements, additional substandard or nonconforming lots can be segregated on a legal lot of record containing more than one primary dwelling unit and septic system consistent with the requirements for a short subdivision under Article III of Chapter 18.35 JCC; provided, that all conditions set forth in this subsection are satisfied:

(a) The parcel to be divided contains more than one existing legally permitted residential structure (not including an approved or functioning accessory dwelling unit), of which all structures have an individual, legally permitted and installed septic system approved by the Jefferson County environmental health department, and neither structure was approved as, or functions as, an accessory dwelling unit (ADU);

(b) If on or before January 20, 1998, the parcel to be divided contained one or more existing legally permitted residential structures, of which each structure had an installed, individual and legally permitted septic system approved by the Jefferson County environmental health department, and the property contained at least one additional legally permitted and installed septic system not yet dedicated or connected to an existing residential structure;

(i) Each of the existing residential units must have been constructed in compliance with all applicable building codes, zoning codes, and county, state and federal laws in effect at the time of construction and/or placement in the case of a manufactured or mobile home, and none of the residential structures were permitted as an ADU and neither structure consists of a recreational vehicle or travel trailer.

(ii) Each of the installed septic systems were legally permitted at the time of installation and are currently functioning properly as determined by the Jefferson County environmental health department, and are in compliance with the applicable environmental health regulations as reviewed and approved by the Jefferson County environmental health department.

(iii) The property may be divided into a number of lots equal to the number of legally permitted and installed septic systems. In rural residential zones the property shall be divided in a manner that creates lots of a size which are as equal as possible or as close to conforming with the minimum lot size or mapped density requirements of this code, whichever is the more restrictive. Lots divided under this section in resource zones shall not be larger than one acre, unless additional area is needed for the septic tank and drainfield.

(iv) Lots created under the exemption authorized in this subsection shall be exempt only from the density or minimum lot size requirements of this code and shall be subject to all other requirements of this code, including the requirement for its own access or agreed upon and legally created shared access (shared easement), as well as compliance with all other applicable county, state and federal laws.

(v) The responsibility to demonstrate that each residential structure was constructed or sited under a valid building permit and/or the regulations in effect at the time of construction, or placement in the case of a manufactured or mobile home, and that each septic system was approved and inspected by the Jefferson County environmental health department shall be that of the proponent.

(vi) The provisions of this subsection shall not apply to any recreational vehicle parks, mobile home parks, campgrounds, camper clubs, seasonal (vacation) homes, park models, or any property developed under a binding site plan.

NOTES:

1. See JCC 18.15.574, Article VI-Q, State Route 20 Highway Visual Corridor (HVC) Overlay District, which implements the intent of 2018 Comprehensive Plan policy LU-P-15.4, and as codified in JCC by Ordinance 11-1218-23. To protect the forest corridor and tree canopy in the Glen Cove area, the setback from the right-of-way of SR 20 shall be 50 feet on each side of the highway (comprised of a 30-foot buffer and a 20-foot setback from the buffer), for new development, from the intersection of Old Fort Townsend Road and SR 20 to the incorporated boundary of the city of Port Townsend.

2. Except if subject to the special setbacks required from adjacent resource lands as specified in Chapter 18.15 JCC.

3. Special Rear and Side Setbacks. Special rear or side setbacks are required:.

a. Wherever a residential use is proposed to abut a commercial use or zone, and vice versa. The setback shall be 35 feet.

b. Wherever a residential use is proposed to abut a light industrial use or zone, and vice versa. The setback shall be 25 feet, unless otherwise specified in this code.

c. Wherever a residential use is proposed to abut a heavy industrial use or zone, and vice versa. The setback shall be 100 feet, unless otherwise specified in this code.

4. Wherever a commercial use is proposed to abut an industrial use or zone, and vice versa. The setback shall be 20 feet, unless otherwise specified in this code.

5. Fences are exempt from setback requirements, except in the jurisdiction of the Shoreline Master Program (SMP) or when impairing safe sight lines at intersections, as determined by the county engineer.

6. Setbacks do not apply to mailboxes; wells; pump houses; bus shelters; septic systems and drainfields (except in the SMP); landscaping (including berms); utility apparatus such as poles, wires, pedestals, manholes, and vaults. No other structures or accessory uses shall be located in the front setback area unless approved by the administrator. The administrator may reduce the minimum road setbacks if the strict application of such setback would render a legal lot of record unbuildable under the provisions of this code.

7. Chimneys, smokestacks, fire or parapet walls, ADA-required elevator shafts, flagpoles, utility lines and poles, skylights, communication sending and receiving devices, HVAC and similar equipment, public water towers or tanks, and spires associated with places of worship are exempt from height requirements.

8. Propane fuel storage tanks and containers shall maintain setbacks and separations pursuant to the currently adopted International Fire Code.

9. Approved subarea plans may establish different bulk and dimensional requirements for those areas.

10. If a development proposal depends on two or more lots or parcels to be considered as one site for purposes of complying with the provisions of this title or of any other provision of the Jefferson County Code, DCD may require an applicant to record a covenant to the benefit of the county that requires the retention of the lots under common ownership and control for the duration that the use is maintained on the site.

11. Road Classifications. To clarify the setbacks for development activities consistent with the requirements of this chapter, the following road designations shall apply:

a. Principal arterials: US 101, SR 104, SR 20.

b. Minor arterials: SR 19 (Beaver Valley Road, Rhody Drive, and Airport Cutoff).

18.30.060 Grading and excavation standards.

(1) General Regulations.

(a) All grading and clearing activities shall be conducted so as to minimize potential adverse effects of these activities on forested lands, surface water quality and quantity, groundwater recharge, and fish and wildlife habitat, adjacent properties and downstream drainage channels.

(b) Grading and excavation to construct ponds and reservoirs shall:

(i) Meet all applicable setbacks specified in this code, except for stormwater detention facilities authorized by the county engineer;

(ii) Maintain in-stream flows of natural drainage courses; and

(iii) Protect adjacent property from damage.

(2) Drainage and Erosion Control. All grading activities shall be accomplished as follows:

(a) Design and maintain adequate buffers of undisturbed native vegetation to minimize off-site impacts of surface water runoff, erosion, and sedimentation.

(b) Design and construct all graded surfaces that are to be revegetated so that the graded surfaces will hold topsoil and to minimize surface runoff, erosion, and sedimentation.

(c) Selectively salvage the upper six to 12 inches of topsoil, stockpile it, and respread over all disturbed areas to be revegetated. Excess excavated material, if not retained on-site, must be disposed of at a permitted site approved by the administrator.

(d) Any area cleared or graded and not covered with gravel or an impervious surface shall be seeded immediately on completion of the project. If erosion is probable, areas with exposed soil shall be protected by temporary means during and following construction until seeding is established. All disturbances should at least be revegetated with grasses and forbs; including shrubs and trees as appropriate in the revegetation effort. Use of plant species native to the county is encouraged.

(e) Natural vegetation shall be retained to the maximum extent possible in construction and operation of any use. All development shall ensure that soil erosion and sedimentation of drainage ways will be controlled to prevent damage to adjoining property and downstream drainage channels and receiving waters.

(f) Surface drainage shall not be directed to or discharged into county roads or ditches within county rights-of-way unless approved by the county engineer.

(g) A drainage analysis shall be prepared if required by JCC 18.30.070. Drainage controls may be required to regulate volume, peak flow and velocities of runoff water and to control pollutants, erosion, and sedimentation if it is probable that damage could occur downstream to property or to water quality. Such controls may include landscaping or re-establishing native vegetation, ponds, catch basins, and other control structures.

(h) For effective long-term weed control, it is suggested that the landowner coordinate with the county weed control board to eradicate nuisance species.

(3) Best Management Practices (BMPs). BMPs from the currently adopted Stormwater Management Manual for Western Washington (SMM) (see JCC 18.30.070) or as specified by the county engineer shall be employed in the control of erosion and sediment during construction, to permanently stabilize soil exposed during construction, and in the design and operation of stormwater and drainage control systems.

(4) Critical Areas. All clearing and grading activities that will adversely affect critical areas shall be subject to the regulations of Chapter 18.22 JCC, and JCC 18.30.070, without limitation to thresholds found herein:

(a) Critical Aquifer Recharge Areas. Standards governing development activities in these areas are found in Article III of Chapter 18.22 JCC.

(b) Frequently Flooded Areas. Fills in flood hazard areas as identified on the FIRM (Flood Insurance Rate Maps) are not permitted unless the administrator finds that no reasonable alternative exists.

(c) Geologically Hazardous Areas. Standards governing development activities in these areas are found in Article V of Chapter 18.22 JCC.

(d) Fish and Wildlife Habitat Areas. Standards governing development activities in these areas are found in Article VI of Chapter 18.22 JCC.

(e) Regulated Wetlands. Alteration (filling, excavating, or draining) of regulated wetlands shall be subject to the provisions of Article VII of Chapter 18.22 JCC.

(5) Grading.

(a) Project or building permits which involve grading of 500 or more cubic yards are subject to environmental review under the State Environmental Policy Act (SEPA) (see Article X of Chapter 18.40 JCC) unless the grading is SEPA-exempt under WAC 197-11-800.

(Note: this does not apply when grading is associated with a development or activity which is categorically exempt from SEPA review requirements. Most minor new construction, including construction of a single-family house and related outbuildings, is exempt from SEPA review; see WAC 197-11-800.)

(b) All grading of 500 cubic yards or more shall be subject to a stormwater management permit, as specified in JCC 18.30.070(5), with the exception of:

(i) Maintenance of gravel roads;

(ii) A SEPA-exempt (cf. WAC 197-11-800(2)(d)) residential driveway;

(iii) Construction of a Class I – III logging road (per RCW 76.09.050 and WAC Title 222); or

(iv) Drainage improvements constructed in accordance with subsection (2) of this section and JCC 18.30.070. [Ord. 14-18 § 4 (Exh. B); Ord. 8-06 § 1]

18.30.070 Stormwater management standards.

All new development and redevelopment must conform to the standards and minimum requirements set by the most current version of the Washington Department of Ecology Stormwater Management Manual for Western Washington (SMM) and obtain a stormwater management permit if required by subsection (5) of this section. The administrator may require additional measures as indicated by the environmental review or other site plan review.

(1) Definitions. For the purposes of this section, the definitions at Section I-2.3 of the SMM shall apply:

(a) “New development” includes land-disturbing activities, including Class IV general forest practices that are conversions from timber land to other uses; structural development, including construction or installation of a building or other structure; creation of impervious surfaces; and subdivision, short subdivision and binding site plans as defined and applied in Chapter 58.17 RCW. Projects meeting the definition of redevelopment shall not be considered new development.

(b) “Redevelopment” includes, on a site that is already substantially developed (i.e., has 35 percent or more of existing impervious surface coverage), the creation or addition of impervious surfaces; the expansion of a building footprint or addition or replacement of a structure; structural development including construction, installation or expansion of a building or other structure; replacement of impervious surface that is not part of a routine maintenance activity; and land-disturbing activities.

(c) “Impervious surface” means a hard surface area that either prevents or retards the entry of water into the soil mantle as under natural conditions prior to development, a hard surface area which causes water to run off the surface in greater quantities or at an increased rate of flow from the flow present under natural conditions prior to development. Common impervious surfaces include, but are not limited to, roof tops, walkways, patios, driveways, parking lots or storage areas, concrete or asphalt paving, gravel roads, packed earthen materials, and oiled, macadam or other surfaces which similarly impede the natural infiltration of stormwater. Open, uncovered retention/detention facilities shall not be considered as impervious surfaces for purposes of determining whether the thresholds for application of minimum requirements are exceeded. Open, uncovered retention/detention facilities shall be considered impervious surfaces for purposes of runoff modeling.

(d) “Land-disturbing activity” is any activity that results in movement of earth, or a change in the existing soil cover (both vegetative and nonvegetative) and/or the existing soil topography. Land-disturbing activities include, but are not limited to, clearing, grading, filling, and excavation. Compaction that is associated with stabilization of structures and road construction shall also be considered a land-disturbing activity. Vegetation maintenance practices are not considered land-disturbing activity.

(2) Exemptions.

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 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.

(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 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.

(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.

(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 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.

(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.

(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.

(B) If the work is done on a regular basis at a stationary business location, move the activity indoors.

(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.

(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.

(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.

(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.

(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.

(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]

18.30.180 On-site sewage disposal best management practices in critical aquifer recharge areas.

All land uses identified in Article III of Chapter 18.22 JCC and special aquifer recharge protection areas that are also classified as susceptible aquifer recharge areas (as defined Chapter 18.22 JCC) shall be designated areas of special concern pursuant to WAC Title 246. Consistent with WAC Title 246, the Jefferson County board of health determines the best management practices (BMPs) to meet minimum on-site sewage standards within both a susceptible aquifer recharge area and a special aquifer recharge protection area (as identified in Article III of Chapter 18.22 JCC). The current BMPs, subject to modification from the Jefferson County board of health, are:

(1) The contaminants of concern, bacteria and nitrogen, are not fully treated (removed) from wastewater in Type 1 and 2 soils (excessively coarse and coarse) with conventional gravity fed on-site sewage systems. To more adequately protect the groundwater in these areas from contamination by these elements the standards in this section have been developed utilizing a combination of treatment systems and land use density parameters.

(2) Where land use densities are such that adequate aquifer protection is not ensured, best management practices for on-site sewage shall apply to new development, or expansion (as defined in WAC 246-272A-0010) of existing development when an on-site sewage disposal system is installed.

(a) Tables 1 and 2 shall be used to determine the type of on-site sewage disposal system required and the minimum lot size in different soil types where public water is available. Lot size requirements are taken from the Washington State On-Site Sewage Code, Chapter 246-272A WAC, Table X. Soil textural classifications and minimum standards for methods of effluent distribution for soil types and depths are taken from Chapter 246-272A WAC, Tables V and VI, respectively.

(b) In critical aquifer recharge areas, no on-site sewage permit will be issued where public water systems are not available on lots less than one acre, except as permitted in subsection (2)(c) of this section.

(c) When lots sizes do not meet the area requirements specified in Tables 1 and 2, and lot consolidation is impracticable, an approved composting toilet and greywater treatment system may be permitted. Permits for composting toilets shall include a condition requiring further treatment of toilet waste at the Port Townsend composting facility or other approved site. On-site use or disposal of the toilet-generated compost shall not be allowed.

(d) BMPs shall be updated as new technologies are reviewed and approved by Jefferson County public health and/or Washington State Department of Health. Criteria for review of new or existing systems will include, but not be limited to, adequate laboratory evidence provided by the system proprietor of a minimum of 50 percent total nitrogen reduction prior to final disposal. Currently, acceptable BMPs include:

(i) Intermittent sand filter followed by a shallow pressure distribution system (also meets Treatment Level B);

(ii) Recirculating gravel filter;

(iii) Composting and incinerating toilets – if these are used, greywater from the facility shall be treated by the method normally required by the site and soil conditions required under Chapter 246-272A WAC. For example: Type 1 soils require Treatment Level B under Chapter 246-272A WAC. Only composting or incinerating toilets on the List of Registered On-Site Treatment and Distribution Products by the Washington Department of Health may be permitted;

(iv) Treatment units listed in Washington State Department of Health Registered Products meeting Treatment Level N.

(e) Systems that meet Treatment Levels A and B and N are listed and approved by the Washington State Department of Health and are available in the List of Registered On-Site Treatment and Distribution Products. Only those systems that meet Treatment Levels specified in Chapter 246-272A WAC and meet Treatment Level N or are listed as nitrogen reduction BMPs (in subsection (2)(d) of this section) meet the standard for critical aquifer recharge area requirements in Type 1 soils.

(f) Where a question/disagreement regarding the soil texture exists the following procedure shall be used:

(i) Sample will be taken in the presence of Jefferson County public health staff.

(ii) Chain of custody protocol shall be followed.

(iii) Lab reports shall be sent to Jefferson County environmental health division and the applicant, or applicant’s representative, for review.
