A. Classification of Aquifer Recharge Areas
1. Classes. Critical Aquifer Recharge Areas are classified as either Class I (Extremely Susceptible),
Class it(Highly Susceptible),Class III(Moderately Susceptible),or Class IV(Low Susceptibility),as
described below.
2_ Methodology_ The aquifer classification system and maps were developed by a qualified geologist in
consultation with the Washington Department of Natural Resources and considering data from the
following sources;
a. Mineral Resources of the Southern Hood Canal Area,Washington;Mackey Smith and R.J.Carson;
Department of Geology and Earth Resources-Geologic Map GM-21; 1976.
b. Geology and Related Water Occurrence,Southeastern Mason County,Washington; Dee Molenaar
and John B. Noble; Water Supply Bulletin No. 29, Department of Water Resources, State of
Washington; 1970.
c. Geologic Map of the South Half of the Shelton and South Half of the Copalis Beach Quadrangles

g. Water Well records.
Interpretation of these data sources was performed by Geologist Gordon Adams. An explanation of
that interpretation is included in a letter from Gordon Adams dated March 29, 1999.
Mason County Resource Ordinance 37 Revised June 16,2009
2. Standards of Classification.
a. Class I(Extremely Susceptible)- Areas designated as Class I demonstrate hydrogeologic characterlstcs
that allow for an extremely high susceptibility of an underground source of ddrnking water.These areas are
identified as recessional outwash of thickness' greater than 25 feet, Recessional outwashes are a
geological formation predominantly composed of underground source of drinking water unconsolidated
sands and gravels. These formations exhibit horizontal permeabilities greater than 30 feet per day
(horizontal permeabilities are generally 10 times less than vertical permeabilities).Potential contaminants
entering an underground source of drinking water can be expected to travel one mile in six months or
less.
b. Class II (Highly Susceptible). Areas designated as Class II demonstrate hydrogeologic characteristics
that allow for a high susceptibility of an underground source of drinking water.These areas are identified
as recessional outwash and alluvium 25 feet or less in thickness. These geologic formations are
composed of unconsolidated sands and gravels interlain with discontinuous layers of hardpan and silty
clays. Depth to water is generally 25 to 125 feet below land surface.These formations exhibit horizontal
permeabilities in the range of 30 to 15 feet per day. Potential contaminants entering an underground
source of drinking water can be expected to travel one mile in a time frame greater than six months and
up to one year.
c. Class 111 (Moderately Susceptible). Areas designated as Class IiI demonstrate hydrogeologic
characteristics that allow for a moderate susceptibility of an underground source of drinking water.These
areas are identified as advance outwash. The geologic formations consist of discontinuous layers of
clayey gravel and sand and layers of silt and clay,which are more continuous and have been compacted
into hardpan. Depth to water is greater than 125 feet below land surface. These formations exhibit
horizontal permeabilities in the range of 15 to 3 feet per day. Potential contaminants entering an
underground source of drinking water can be expect to travel one mile In a time frame greater than one
year and up to five years. Class III areas Include those well head protection areas, not otherwise
designated as a Class I,11,or III critical recharge area,and recorded with the Mason County Department
of Community Development.
d. Class IV(Low Susceptibility),Areas designated as Class IVdemonstrate hydrogeologic characteristics that
allow for a low susceptibility of an underground source of drinking water.These areas are identified as
advance outwash found in the southwest part of Mason County along the Satsop drainage.
B. Designation
The lands and fresh waters of Mason County meeting the Critical Aquifer Recharge Areas Classification,plus
300 feet beyond the mapped boundary of all Class I, II or Iii areas, are hereby designated under RCW
Chapter 36.70A as Critical Area Protection Zones requiring protection for public health.
C. Pre-existing Uses
Uses legally existing as of the date of adoption of this ordinance and which are listed under Sections D_ (Prohibited
Uses and Activities)or E.(Uses Requiring an Environmental Permit)are defined to be pre-existing uses.Pre-existing
uses may continue operation pursuant to the following provisions and procedures.The purpose of these provisions is
to assure that pre-existing uses that represent a threat to the aquifer are brought into compliance with the provisions of
this chapter over time and to the highest degree possible.These provisions shall not be construed to mean that a pre-
existing business must cease operations even if the type of business operates as a prohibited use per section D.
below.The following procedures and requirements are hereby established;
Upon identification of a legal pre-existing use,the county shall contact the operator and/or owner in orderto develop a
compliance plan and time line for bringing the pre-existing use into compliance to the highest degree practicable and
which provides an acceptable low level of risk to the aquifer.
1. The County will negotiate with the ownerioperator to identify a reasonable time frame and necessary steps
to bring the use into compliance with this chapter.

2. Technical assistance will be offered the owner/operator by state andlor local personnel to enable the
owner/operator to bring the operation into compliance.
3. The County will require that a written compliance plan be developed and agreed to by the owner/operator
setting forth the compliance steps that will be taken and the agreed time frame underwhich these steps
will be completed.
4. The compliance plan shall be agreed to in a reasonable time as defined by the Director on a case-by-case
basis.
5. Such compliance plan will take the form of a contract between the County and the owner/operator.
6. No expansion of any non-conforming aspect of the use or business activity will be permitted.
7. Failure to meet the terms of the contract, including time frames agreed to, shall constitute a breach of
contract subject to all applicable law. If legal action on the part of the County becomes necessary to
enforce the contract,the owner/operator shall be liable for all legal expenses.

F. Subdivision Standards and Evaluation Requirements.
1. Subdivision,short subdivisions and other divisions of[and in areas of special concern shall be evaluated
for their impact on groundwater quality as follows:
a_ In urban growth areas, land divisions may be allowed which create lots less than one acre in size
which rely on individual on-site septic systems. Such approvals shall be conditioned so that the total
development allowed within the area to be divided shall not exceed an average density of one
dwelling unit per acre, or an equivalent waste-water volume, until such development is served by
public sewer.
b. In urban growth areas, land divisions may be allowed which create lots less than one acre in size
which rely on a community on-site septic systems.Such approvals shall be conditioned so that the
total development allowed within the area to be divided shall not exceed an average density of one
dwelling unit per acre, or an equivalent waste-water volume, until such development is served by
public sewer. in addition, said system shall be evaluated to assure that it does not have localized
effects that might have a significant adverse impact on wells orsurfacewaterbodies.Information for
the evaluation shall be provided by the applicant in the form of a Site Evaluation Report as specified
in subsection M.2.
c, Outside of urban growth areas,subdivisions which provide for clusters of residential development
where the density of the cluster of residential lots exceed one lot per acre,orwhere development will
rely on a community on-site septic system, shall be evaluated to assure that they do not have
localized effects that might have a significant adverse impact on wells or surface water bodies.
Information for the evaluation shall be provided by the applicant in the form of a Site Evaluation
Report as specified in subsection M.2.
2. Approval of a permit for 1. b. or c. above shall be based on a review of the report and a determination
that there are no probable significant adverse impacts to wells,springs,surface water bodies,or off-site
ground water quality.
G. On-site Septic System Standards
1. The proper operation and maintenance of community or on-site septic systems is required in the critical
aquifer recharge areas. The standards and procedures to be met to assure this are as set forth in the
"Mason County On-Site Sewage Operation and Maintenance Program" and any subsequent
implementing regulations.Participation in this program is mandatory for existing and new septic systems
in the critical aquifer recharge areas.
Mason County Rescufre Ordinance 40 Revised June 16,2009
2. New construction
a. New construction which relies on on-site septic systems shall not be allowed to exceed a density of
one dwelling unit per acre,or an equivalent waste-water volume,exceptforthe development of one
dwelling on lots existing or vested by December 5, 1996,where the on-site septic system can comply
with all Environmental Health Department standards.For the purposes of this section,the sewage
flow of one single family dwelling equals one unit volume of sewage equals 450 gallons perday.An
exception to this may be made where a sewage treatment system or plant is used that processes the
effluent so that the total of contaminants is equivalent to or less than that which would be produced
by one dwelling unit per acre in suitable soils using individual on-site septic systems.The intensity of
non-residential development that is allowed In compliancewith this standard shall be calculated from
Table 1. Alternative calculations for activities not included in Table 1 may be proposed, but the
calculation method and conclusions must be approved by the County Environmental Health
Department.
b. Where such development relies on a new on-site sewage treatment plant or other new on-site
community septic system, said plant or system shall not have localized affects that might have a
significant adverse impact on wells or surface water bodies. Information for the evaluation shall be
provided by the applicant in the form of a Site Evaluation Report as specified in subsection M.2.
Approval of a permit shall be based or a review of the report and a determination that there are no
probable significant adverse impacts to wells,springs,surface water bodies,or off-site ground water
quality.
3. All new development within the designated urban growth areas,except for single-family residences built
prior to the opportunity to connect to a public sewer system, shall be required to connect to existing
public sewer systems,or to proposed public sewer systems as soon as connection is available.
H. Well Head Protection Area -Notice
Within well head protection areas,in addition to any other notice requirements,notice shall be provided to the
manager of said area for any applications for an Environmental Permit for the Critical Aquifer Recharge Area
or for any long subdivisions.
I. Standards for an Environmental Permit for the Critical Aquifer Recharge Area
To receive an Environmental Permit to operate in the Critical Aquifer Recharge Area an applicant must,
1. Implement Best Management Practices (BMP), implement the Washington State Department of
Ecology's Storm Water,Water Quality,Hazardous Waste,Wetland,and Solid Waste Program BMP and
BMP from the Departments of Health,Agriculture,Transportation,and State Conservation District Office,
or
2. Demonstrate through a Best Management Practices Report pursuant to subsection M.1.below,howthey
will integrate other necessary and appropriate mitigating measures in the design, installation, and
management of the proposed facility or use,and
3. Provide a written agreement to the County providing that all employees at the site will be notified that the
operation lies above an aquifer recharge area and providing annual training regarding all measures set
forth by the BMP established in subsection 1. 1 or 2 above.
J. BMP Monitoring and Inspection.
To assure that Hest Management Practices are implemented and maintained over time, the following
procedures and requirements are hereby established:
Mason County Resource Ordinance 41 Revised June 16,2009
1. The county will maintain a data-base identifying all pre-existing prohibited uses or uses requiring a permit
under the provisions of this section. Information for this purpose will be gathered from applicants for
development permits and by consultation with appropriate state agencies. During pre-application
meetings or on application, the county will require applicants to identify if they are required to have a
hazardous waste identification number by the Washington State Department of Ecology and whether
they generate any hazardous waste as defined under WAC 173-303.
2. Inspection and monitoring procedures.
As a condition of approval, regular inspections for compliance will be required as appropriate to the
activity, but not less than once in two years.The first inspection shall be made within 3 months of the
issuance of the certificate of occupancy for the project.
K. Map Amendments
Applicants may seek to have the Aquifer Recharge Map amended as it pertains to the parcel or parcels for
which they are applying. The application will be for a conditional environmental permit.This may be granted
after the applicant demonstrates to the satisfaction of the county that site conditions meet the standards of
classification per subsection C.for the Aquifer Area Class sought.
Such demonstration shall be accomplished by providing a Map Amendment Report per subsection M.2.to the
county. The County shall evaluate the Report and make a written determination as to whether the map will be
amended. Approval of the map amendment requires that,based on the best available science,the site does
not qualify as a critical aquifer recharge area, or qualifies as a different lass designation from its current
designation, as applied by the County pursuant to the Growth Management Act.
The report shall be reviewed by the County in conjunction with the underlying permit process, If any exists.
The review process shall be a public review as specified in subsection 17.01.120 E. 2. b. The County may
consult with the Mason County Health Department,State of Washington Department of Health,independent
reviewer, or any other parties it sees fit. The County will review the report with consideration of the level of
science that currently exists and was employed to make the map designation being challenged. The applicant
will not be required to provide information and/or analysis in excess of that required to convince the County
that a map change is warranted.
In addition,the County will re-assess all Map Amendment Reports and all other pertinent information received
on a periodic basis and consider other appropriate map amendments on the basis of this increased
information.
L. Reclassification of Specific Land Use Activity
Applicants may seek to have the use for which they are applying able to receive a Aquifer Areas Protection
Permit per subsection E. This may be granted after the applicant demonstrates to the satisfaction of the
County,that the use proposed applies new technologies and/or procedures,nottraditional to the industry,that
reduce the threat to the aquifer beyond that posed by the traditional technologies and/or procedures to a
degree that the County determines will justify the reclassification.
Such demonstration shall be accomplished by providing an Activity Reclassification Report per subsection M.
3.to the County. The County shall evaluate the Report and make a written determination as to whether the
individual proposed land use will be recategorized. Review of the application shall be a public review as
provided in section 17.01.120 2.b.Reclassification of a land use shall apply only to the particular use for which
the reclassification Is sought and shall not be applied to all or any similar uses.
In addition, the County will re-assess all Reports received pursuant to this chapter and all other pertinent
information received on a periodic basis and consider the other changes in the categorization of land uses in
this chapter on the basis of this increased information.
