18.30.010 General provisions.
(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, water courses, 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. 11-00 § 6.1]
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;
Draft 6/26/06
(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 both to serve the proposed land use and to avoid adverse effects to the existing transportation
system. If transportation facilities are inadequate, the applicant shall be required to make provision for
necessary improvements. 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. 11-00 § 6.2]
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 health and human services.
(1) All development must conform to the requirements of the Jefferson County health department 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 the Jefferson County department of 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. 11-00 § 6.3]
18.30.040 Sewage disposal.
(1) All development shall be provided with an individual, on-site septic system and drainfield approved by
the Jefferson County health department in compliance with Chapter 8.15 JCC, unless the Jefferson County
health department 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 the
Jefferson County department of health or the agency having regulatory responsibility for the system. [Ord. 3-01
§ 1; Ord. 11-00 § 6.4]
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 code:
(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) 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.
(d) "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,
earth—, and otried surft c -es -_Open, uncovered retention/detention facilities shall not be considered as impervious
surfaces. See also JCC 18.30.070 for storm drainage standards.
Draft 6/26/06 2
(e) The height of buildings and structures shall be calculated by the vertical distance from grade plane to the
aver rage height of the highest roof surface. Storo� 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). e -t_
(4) Density Exemptions. In land use districts with minimum density requirements, up to one additional
substandard or nonconforming lotslet 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;
(c) The following conditions shall apply to all density exemptions authorized under this subsection:
(i) A pr-opefty owner- who fneets the or-iter-ia in subseetion (4)(b) of this section and has fflefe than 0
unconnected, but legally per-mitted and installed n approved by the jeffer-sen County envir-onfn ntal.
health department shall only be allowed to or -eat ne. -A-Ldifleenal lot through the sheFt plat process, regardless of
the total numbef of legally permitted and installed, but undedicated septic 'I 'he property.
(ii)—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.
(iii) 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.
(iv) 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 Thethe 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 1 acre, unless additional area is needed for the septic tank and drainfield.
(v) 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
Draft 6/26/06
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.
(vi) 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.
(vii) 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

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,
ground water 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 the Puget c^,,,,,a Bftsi 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
Draft 6/26/06 7
exposed during construction, and in the design and operation of stormwater and drainage
control systems.
(4) Environmentally Sensitive Areas. All clearing and grading activities that will
occur - n -or -adversely affect environmentally sensitive areas shall be subject to the
regulations of Article VI -D et seq. of Chapter 18.15 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 VI -E of Chapter 18.15 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 VI -G of Chapter 18.15 JCC.
(d) Fish and Wildlife Habitat Areas. Standards governing development activities in
these areas are found in Article VI -H of Chapter 18.15 JCC.
(e) Regulated Wetlands. Alteration (filling, excavating, or draining) of regulated
wetlands shall be subject to the provisions of Article VI -I of Chapter 18.15 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(6), 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 222);
(iv) Drainage improvements constructed in accordance with subsection (2) of this
section and JCC 18.30.070; or
(v) Construction of a pond of one-half acre or less which is not in a regulated
wetland. [Ord. 11-00 § 6.6]
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 (65) 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 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
Draft 6/26/06 $
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. Commercial agriculture, road maintenance activities, and forest
practices regulated under WAC Title 222, except for Class IV General forest practices
and COHPs (see JCC 18.20.160), pursuant to SMM Section I-2.2, are exempt from the
provisions of the minimum requirements.
(3) Development and Redevelopment Minimum Requirements. Development and
redevelopment meeting the criteria of subsection (1)(a) of this section shall be required to
control erosion and sediment during construction and to permanently stabilize soil
exposed during construction. Such development shall:
(a) Comply with the minimum requirements for development of small parcels in
Section I-2.5 of the SMM;
(b) Applicants for all development and redevelopment meeting the criteria for
subsection(l)(a) of this section, except for detached single-family residences and
duplexes creating or adding less than 2,000 square feet and land -disturbing activities of
less than 7,000 square feet, shall prepare a stormwater site plan (or, show on other
diagrams being prepared for the project, if appropriate) showing:
(i) Vicinity map;
(ii) Location of the structure and its access;
(iii) All applicable setback requirements;
Draft 6/26/06
(iv) Location of all applicable erosion and sediment control BMPs; and
(v) Existing site features and sensitive areas.
(4) New Development Minimum Requirements.
(a) All new development and redevelopment shall be required to comply with
Minimum Requirement #2 (Construction Stormwater Pollution Prevention) as contained
in the SMM.
(b) New development that includes: (i) the creation or addition of 2,000 square feet,
or greater, of new, replaced, or new plus replaced impervious surface area; or (ii) has

archaeological artifacts and data as identified by appropriate state, federal or tribal
agencies, the county shall not take action on the application and shall inform the
applicant thereof, and the applicant shall not initiate any excavation or development
activity until the site has been inspected and a written evaluation is provided by a
qualified archaeologist. Significant archaeological data or artifacts must be recovered
before work begins or resumes on a project. No application will be delayed more than ten
working days for such an inspection. If the application is approved by the county,
conditions shall be attached reflecting the recommendations of the archaeologist
regarding preservation or protection of the site.
Draft 6/26/06 25
(2) All permits shall contain a special provision advising the permit holder that if
during excavation or development of the site an area of potential archaeological
significance is uncovered, all activity in the immediate vicinity of the find must be halted
immediately and the administrator must be notified at once. Activities authorized by the
permit will not be delayed more than five working days for a finding of significance by
the administrator, following the administrator's receipt of notification, unless the permit
holder agrees to an extension of that time period.
(3) All development proposed for location adjacent to sites which are listed, or are
determined by the appropriate state or federal authority to be eligible for listing in the
state or national registers of historic places, must be located so as to complement the
historic site. Development which degrades or destroys the historical character of such
sites is not permitted.
(4) Archaeological sites are subject to Chapter 27.44 RCW (Indian Graves and
Records) and Chapter 27.53 RCW (Archaeological Sites and Records) and must comply
with Chapter 25-48 WAC (Archaeological Excavation and Removal Permit).

(5) Identified historical or archaeological resources must be considered in site
planning for public parks, public open space, and public access and site planning, with
access to such areas designed and managed so as to give maximum protection to the
resource. [Ord. 11-00 § 6.16]
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(l)(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 sed
in mixing and productiondv'a��hrirg ^vf eildiprirtir*, armed iir rirrrning�'cird pi^vuact in much
tie same=may 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.
Draft 6/26/06 26
(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 waste water
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.
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.
Draft 6/26/06 27
(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.
(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
Draft 6/26/06 28
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 deicing
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.
(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
Draft 6/26/06 29
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.
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
Draft 6/26/06 30
(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
Draft 6/26/06 31
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.

Jefferson County health department, when the following conditions are present.
(1) The contaminants of concern, bacteria and nitrogen, are not fully treated
(removed) from wastewater in Type IA and 2A soils (excessively 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 insured,
best management practices for on-site sewage shall apply to new development, or
expansion (as defined in WAC 246-272-01001) 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 246-272 WAC, Table VII. Soil textural classifications and minimum
standards for methods of effluent distribution for soil types and depths are taken from
Chapter 246-272 WAC, Tables II 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
Draft 6/26/06 32
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 environmental 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 Standard 2);
(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 246-272 WAC. For example: Type I soils require Treatment
Standard 2 under Chapter 246-272 WAC. Only composting or incinerating toilets listed
as approved proprietary devices by the Washington Department of Health may be
permitted.
(e) Systems that meet Treatment Standard 2 are listed and approved by the
Washington State Department of Health and are available in the Guidelines for the
Application of Treatment Standards 1 and 2. Only those systems that meet Treatment
Standard 2 and are listed as nitrogen reduction BMPs (in subsection (2)(c) of this section)
meet the standard for critical aquifer recharge area requirements in Type IA 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 health department 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.
