The city council finds the following:
A. Groundwater supplies the drinking water used by the citizens of Shelton and the water critical to commerce.
B. The city shall designate and protect critical aquifer recharge areas used for potable water pursuant to Chapter 36.70A RCW.
C. Experience throughout the state and nation is that a major cause of potential groundwater contamination is from accidental or improper release of hazardous substances resulting from spills, leaks or discharges. As future growth and development occur, groundwater will become increasingly important. The safety and potability of the community’s water supply requires that lands near to public and private water supply wells and their recharge areas be subject to source control regulations designed to prevent such spills, leaks or discharges or to prevent uses injurious to the public water supply.
D. Adequate protection of the quality and quantity of potable water supplies is in the short and long term economic interest of the community.
E. Due to the large number of individuals and commercial interests dependent on groundwater as their principal source of drinking water and the possibility of contamination, the council finds that providing the protections contained herein serves the public health, safety and general welfare. (Ord. 1921-0518 (part), 2018; Ord. 1516-0499 § 1 (part), 1999: Ord. 1492-0298 § 1 (part), 1999)
A. The intent of this chapter is to designate areas and provide regulations for the purpose of protecting areas within the city critical to maintaining groundwater recharge quantity and quality for current use and future generations. These actions are intended to satisfy the requirements of the Growth Management Act, Water Pollution Act, Water Resources Act of 1971, and Ground Water Quality Standards as well as the city’s responsibility to its citizens to guarantee continued water quality and adequate supply.
B. This chapter shall define and employ a scientifically valid methodology by which the city will designate such areas and create such regulations. Regulations will be enacted when development within these areas is proposed to occur.
C. The intent of this language is to clearly convey the purpose of this chapter, which is to define and regulate aquifer recharge areas. However, it is also intended that this chapter is holistic in nature. By addressing the specific requirements of the Growth Management Act, it also addresses local response to larger issues of groundwater protection specified in the Water Pollution Control Act and Water Resources Act of 1971, and is in conformance with Washington’s antidegradation policy. (Ord. 1516-0499 § 1 (part), 1999: Ord. 1492-0298 § 1 (part), 1999)

A. Classes. Critical aquifer recharge areas are classified as either Class I (extremely vulnerable), Class II (highly vulnerable), or Class III (moderately vulnerable) as depicted on the Aquifer Recharge Areas Maps herein adopted as Attachment A to the ordinance codified in this chapter.
B. Methodology. The aquifer classification system and maps were developed by a qualified geologist considering data from the following sources:
1. 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;
2. 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;
3. Geologic Map of the South Half of the Shelton and South Half of the Copalis Beach Quadrangles Washington; Robert L. Logan; Washington Division of Geology and Earth Resources; Open File Report 87-9; 1987;
4. Geologic Map of North Central Mason County; R.J. Carson; Department of Geology and Earth Resources; Open File Report 76-2; 1976;
5. Soil Conservation Maps for Mason County Washington; various;
6. Topographic maps for Mason County; various;
7. Water well records.
Interpretation of these data sources was performed by geologist Gordon Adams. An explanation of that interpretation is included in a letter to the city of Shelton dated November 16, 1998.
C. Standards of Classification.
1. Class I (Extremely Vulnerable). Areas designated as Class I demonstrate hydrogeologic characteristics that define an extremely high susceptibility of an underground source of drinking water (USDW). These areas are identified as recessional outwash of thickness greater than twenty-five feet. Recessional outwashes are a geological formation predominantly composed of unconsolidated sands and gravels. These formations exhibit horizontal permeabilities greater than thirty feet per day (vertical permeabilities are generally ten times less than horizontal permeabilities). Potential contaminants entering a USDW can be expected to travel one mile in six months or less.
2. Class II (Highly Vulnerable). Areas designated as Class II demonstrate hydrogeologic characteristics that define a high susceptibility of a USDW. These areas are identified as recessional outwash and alluvium twenty-five 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 twenty-five to one hundred twenty-five feet below land surface. These formations exhibit horizontal permeabilities in the range of thirty to fifteen feet per day. Potential contaminants entering a USDW can be expected to travel one mile in a time frame greater than six months and up to one year.
3. Class III (Moderately Vulnerable). Areas designated as Class III demonstrate hydrogeologic characteristics that define a moderate susceptibility of an USDW. 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 one hundred twenty-five feet below land surface. These formations exhibit horizontal permeabilities in the range of fifteen to three feet per day. Potential contaminants entering a USDW can be expected to travel one mile in a time frame greater than one year and up to five years.
D. Buffers. A three-hundred-foot buffer area is established beyond the boundary of all Class I, II and III areas. The buffer is established to protect designated areas from influence by surface flows and will be considered to be an aquifer recharge area receiving the same protections as Class I, II and III areas. (Ord. 1516-0499 § 1 (part), 1999: Ord. 1492-0298 § 1 (part), 1999)

2. Moderate risk waste, petroleum products, and hazardous materials shall be kept in containers and shall be stored in such a manner and location that if the container is ruptured, the contents will not discharge, flow, be washed or fall into surface water or groundwater. This does not supersede any regulations as stated in the International Fire Code.
3. Underground Storage Tanks and Vaults. Underground storage tanks and vaults used for the storage of petroleum products, wastewater, or hazardous substances or dangerous wastes as defined in Chapter 173-303 WAC, or any other substances, solids, or liquids in quantities identified by the Mason County health department environmental health section, consistent with Chapter 173-303 WAC, as a risk to groundwater quality, shall conform to Chapter 173-360 WAC and be accompanied by a design and management plan prepared by a qualified professional to assure that the facility is designed, constructed and operated so as to:
a. Prevent release, corrosion, or structural failure for the operational life of the tank or vault;
b. Be cathodically protected against corrosion, constructed of noncorrosive material, or steel clad with a noncorrosive material, or designed in a manner to prevent the release or threatened release of any stored substance;
c. Use material in the construction or lining of the tank which is compatible with the substance to be stored;
d. Provide for release detection method(s);
e. Provide a written spill response plan;
f. Provide groundwater monitoring facilities.
4. Divisions of Land. Subdivisions, short subdivisions, and other divisions of land shall be evaluated for their impact on groundwater quality. The following measures may be required as determined by the director:
a. An analysis by a qualified professional of the potential nitrate loading to the groundwater may be required to assess the impact on groundwater quality.
b. Alternative site designs, specific sewage disposal or stormwater facilities may be required to reduce contaminant loading where site conditions indicate that the proposed action will measurably degrade groundwater quality.
c. Phased development and/or groundwater quality monitoring if there is uncertainty regarding potential adverse effects on groundwater.
d. Stormwater runoff treatment shall meet Level 3 water quality standards as provided in the 2005 Ecology Stormwater Manual for Western Washington, or the equivalent.

(Ord. 1689-1206 § 6, 2007: Ord. 1516-0499 § 1 (part), 1999: Ord. 1492-0298 § 1 (part), 1999)
To assure that best management practices are implemented and maintained over time, the following procedures and requirements are established:
A. Development of a City Database of Information Identifying All (Pre-Existing) Prohibited Uses or Uses Requiring an Aquifer Recharge Area Protection Permit.
1. Applicants for business license or business license renewal will be required 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 Chapter 173-303 WAC.
2. During all formal site plan review meetings and other appropriate contacts with applicants for construction permits, the city 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 Chapter 173-303 WAC.
3. The city will consult with all appropriate state agencies and existing data to further identify such businesses.
B. Inspection and Monitoring Procedures.
1. The city manager or designee will appoint appropriate city personnel to perform inspections of businesses or activities identified as requiring best management practices per Section 21.66.060 or as uses legally existing at the time of adoption of this chapter as per Section 21.66.090.
2. Inspections will be performed not less frequently than biennially. Upon issuance of a certificate of occupancy for a new business affected by this chapter or first renewal of a business license for an existing business affected by this chapter occurring after adoption of this regulation, inspection will occur in not more than three months.
3. City inspectors will operate as technical advisors and as information providers to the highest degree possible.
4. If city personnel are unable to make accurate determinations regarding corrective actions that may be necessary at a site, they will consult with appropriate state agencies.
1. Parties identified as failing to observe and implement BMPs will be notified to correct the failure and given technical assistance, either by appropriate state personnel, or by the city and/or its consultant. In the course of such technical assistance the party and city shall attempt to reach agreement as to what steps and timelines are necessary to gain compliance with BMPs, and to reach such agreement in a timely manner.
2. If the city deems that timely agreement cannot be reached, or that agreement as to the appropriate steps necessary to achieve compliance cannot be reached, then it can, at its option, hire an outside party (consultant) to provide a written recommendation in this regard. The applicant will be responsible for paying all costs associated with the hiring of this consultant.
3. Failure to correct the problem in a timely manner, as defined by the city manager’s designee, will be deemed a violation of this title and punishable by all provisions of Section 20.56.010 of the Shelton Municipal Code.

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 appears as a prohibited use per Section 21.66.050. The following procedures and requirements are established:
A. Development of a database of information identifying all pre-existing prohibited uses or pre-existing uses requiring an aquifer recharge area protection permit.
1. Applicants for business license renewal will be required 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 Chapter 173-303 WAC.
2. During all formal site plan review meetings for expansion or remodel of such uses and other appropriate contacts with applicants for construction permits, the city 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 Chapter 173-303 WAC.
B. Identification of a compliance plan and timeline 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 city will negotiate with the owner and/or operator of any use identified under subsection A of this section 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 a combination of state and/or local personnel to enable the operator/owner to bring the operation into compliance.
3. The city 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 under which these steps will be completed.
4. The compliance plan shall be agreed to in a reasonable time as defined by the city manager’s designee on a case-by-case basis.
5. Such compliance plan will take the form of a contract between the city and the owner/operator.
6. No expansion of any nonconforming 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 city becomes necessary to enforce the contract, the owner/operator shall be liable for all legal expenses. (Ord. 1921-0518 (part), 2018; Ord. 1516-0499 § 1 (part), 1999: Ord. 1492-0298 § 1 (part), 1999)
A. Applicants may seek to have the aquifer recharge map amended as it pertains to the parcel or parcels for which they are applying. This may be granted after the applicant demonstrates to the satisfaction of the city that site conditions meet the standards of classification per Section 21.66.040 for the aquifer area class sought.
B. Such demonstration shall be accomplished by providing a site evaluation report per Section 21.66.120(B) to the city. The city shall evaluate the report and make a written determination as to whether the map will be amended.
C. In addition, the city will re-assess all site evaluation reports and all other pertinent information received on a periodic basis and consider other appropriate map amendments on the basis of this increased information. (Ord. 1516-0499 § 1 (part), 1999: Ord. 1492-0298 § 1 (part), 1999)
A. Applicants may seek to have the use for which they are applying recategorized as able to receive an aquifer areas protection permit per Section 21.66.060. This may be granted after the applicant demonstrates to the satisfaction of the city that the use applies new technologies and/or procedures, not traditional to the industry, that reduce threat to the aquifer beyond that posed by the traditional technologies and/or procedures to a degree that the city determines will justify the reclassification.
B. Such demonstration shall be accomplished by providing an activity reclassification report per Section 21.66.120(C) to the city. The city shall evaluate the report and make a written determination as to whether the individual proposed land use will be recategorized.
C. In addition, the city will re-assess all reports received pursuant to this chapter and all other pertinent information received on a periodic basis and consider other changes in the categorization of land uses in this chapter on the basis of this increased information. (Ord. 1516-0499 § 1 (part), 1999: Ord. 1492-0298 § 1 (part), 1999)

4. The report will identify appropriate BMPs and how they will be employed to prevent degradation of groundwater. All necessary technical data, drawings, calculations and other information to describe application of the BMPs must be supplied.
5. Groundwater quality monitoring may be required in cases where groundwater contamination is considered a credible risk. Said monitoring plan shall be developed by a qualified professional, be approved by the county, and will be conducted at the expense of the property owner and/or occupying business or enterprise having conducted the activities identified in this subsection.
6. The report will 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. A specific response plan may be required.
7. The report will be reviewed by the planning department or a consultant hired by the city for this review. The Mason County health department and other state, local and federal agencies with regulatory authority over hazardous materials shall be notified of the application and invited to comment.
B. Map Amendment Report—Criteria. The following criteria shall apply when preparing a site evaluation report:
1. A qualified groundwater professional will make a determination whether the proposed map amendment will have adverse impacts on groundwater based on the requirements of the Safe Drinking Water Act and the Wellhead Protection Program, pursuant to public water supplies, Chapter 264-290 WAC; water quality standards for groundwaters of the state of Washington, Chapter 173-200 WAC; and dangerous waste regulations, Chapter 173-303 WAC. Those chapters of Washington Administrative Code are adopted, as written or hereafter amended, as part of this chapter by reference. They are available at city offices.
2. Map amendment reports shall include the following:
a. Identification of features of the proposed development plan (e.g., on-site septic systems and other on-site activities) that may adversely impact groundwater quality underlying or down gradient of the project or project area;
b. Drawing in an appropriate scale showing location of abandoned and active wells, springs and surface water bodies within one thousand feet of the project limits;
c. A description of the geologic and hydrologic characteristics of the subject property sufficient to justify the map amendment sought. This information may include any or all of the following:
i. Lithologic characteristics and stratigraphic relationships;
ii. Aquifer characteristics including recharge and discharge areas, depth to and static water flow patterns, and estimated groundwater flow velocity;
iii. Contaminant rate and transport including probable migration pathways and travel time of a potential contaminant release from a site through the unsaturated zone to the aquifer(s) and through the aquifers(s), and how contaminant(s) may be attenuated within the unsaturated zone and the aquifer(s);
iv. Appropriate hydrogeologic cross sections which depict lithology, stratigraphy, aquifer, units, potential or probable contaminant pathways from a chemical release, and rate of groundwater flow;
v. Existing groundwater quality, proposal for a groundwater monitoring plan to detect changes and indicate the corrective actions that will be taken if monitoring results indicate contaminants from the site have entered the underlying aquifer(s);
vi. Existing soils types and characteristics;
vii. A discussion of the probable geologic history of the site and its impact on aquifer formation, soils conditions and aquifer susceptibility.
3. The report shall be reviewed by the city in conjunction with the underlying permit process, if any exists. The city 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 city that a map change is warranted or of a significantly higher level of detail than used to make the existing designation. The city may request consultation with the Mason County health department, state of Washington Department of Health, independent reviewer, or any other parties it sees fit.
C. Activity Reclassification Report—Criteria. The following criteria shall apply when preparing an aquifer area land use reclassification report:
2. The report shall contain a complete description of the activity for which reclassification is being sought. This description shall include all necessary technical data for the city to assess potential threat to the aquifer from an unmitigated operation, including chemicals and substances used, byproducts produced, etc.
3. The report shall present best management practices and/or mitigation techniques adequate to ensure, to the satisfaction of the city, that the activity or land use for which reclassification is sought will present no greater threat to groundwater quality than other uses listed in this chapter in the category being sought. The burden is on the applicant to make this showing sufficient in the eyes of the city to reclassify the use. The report will include all technical data necessary, design drawings, specifications for equipment used, performance data on equipment or structures, and any evidence or testimony of successful operation of same or similar facilities and practices in other locations.
4. The report will demonstrate to the satisfaction of the city that reclassification of a land use will have no adverse impacts on groundwater based on the requirements of the Safe Drinking Water Act and the Wellhead Protection Program, pursuant to public water supplies, Chapter 264-290 WAC; water quality standards for groundwaters of the state of Washington, Chapter 173-200 WAC; and dangerous waste regulations, Chapter 173-303 WAC.
