The purpose of this Drinking Water Protection Plan is to protect the water quality within the Upper Coast Fork Willamette watershed, the sole source of drinking water for the Creswell community. The Creswell Plan process involved the public and utilized local knowledge. The Source Water Assessment (DEQ, 2002) for the Creswell Drinking Water Source Area was in the process of being updated and enhanced through during the creation of this plan. Updated data sets were used to help inform and guide recommendations. The Plan process included: • Researching and providing useable information on sensitive areas and potential contaminant sources. • Incorporating Committee knowledge and research information into an enhanced inventory. • Utilizing existing risk information and local knowledge to refine risk ratings for potential contaminant sources. • Developing management strategies to reduce or eliminate the risks to the drinking water source posed by potential contaminant sources. • Developing a Contingency Plan that identifies the primary potential threats to the water supply, and presents procedures that will be followed should the threats materialize. • Documenting a procedure for siting future water systems that outlines the steps that would need to be taken if the existing Upper Coast Fork Willamette River source should become unusable or if community growth requires more capacity than is available from the present source. The Plan is recognized as a useful tool for protecting the viability of businesses and households in the City of Creswell and within the watershed. The Plan will be approved by the Oregon Drinking Water Services (DWS) under the Oregon Health Authority, as well as the Department of Environmental Quality. Key strategies for implementation for the plan include: • Continue participation in the Upper Willamette Drinking Water Protection Partners • Conduct targeted outreach and education to private landowners in the Upper Coast Fork Willamette Watershed to inform them their property is located in the Drinking Water Source Area. • Conduct targeted outreach to private industry located between the City of Cottage Grove and the City of Creswell’s drinking water intake facility. • Prioritize riparian restoration efforts and removal of hazardous waste along the mainstem Coast Fork Willamette River between the City of Cottage Grove and the City of Creswell to increase resiliency prior to potential contaminations occurring. 1 • Collaborate with partners and regulatory agencies who provide restoration, education, and or outreach relevant to source water protection outside the City of Creswell jurisdictional boundaries. • Develop recognition for industrial, commercial, and residential landowners that are going above and beyond to ensure and protect the drinking water for the City of Creswell. • Review progress of implementation on an annual basis to ensure steps are continuously being made to strengthen the security and resiliency of the drinking water for the citizens of Creswell.

The Technical Advisory Committee reviewed inventory information, provided local knowledge for the inventory of potential contaminant sources, participated in the ranking of the potential contaminant sources, and assisted in the development of management strategies to address potential contaminant sources. The Technical Advisory group provided information during Plan meetings, and also provided technical advice via email, conversations, and published documents. All parties involved in the process, and interested parties that may present themselves in the future, will be critical for the successful implementation of this Plan.

The U.S. Environmental Protection Agency (EPA) developed guidelines for implementing the new requirements to conduct “source water assessments.” In Oregon, the Oregon Health Authority (OHA) and the Department of Environmental Quality (DEQ) conducted the source water assessments. The Source Water Assessment (SWA) for the City of Creswell was completed in 2002. The City of Creswell SWA included a delineation of the source area supplying the public water system, identification of areas sensitive to contamination, an inventory of potential contamination sources in the area, and a susceptibility analysis. The purpose of the Drinking Water Protection Plan is to build on the information provided in the Source Water Assessment and utilize local and expert knowledge to determine management strategies to protect the water source (ODEQ/OHA, 2002). A state approval process for local jurisdictions that develop plans is included in the state voluntary drinking water protection program. The DEQ and OHA Administrative Rules provide the framework for developing a drinking water protection program leading to this approval. The voluntary drinking water protection program is built on the belief that local communities are best suited to developing their own drinking water protection program based on the needs and land uses within the community. The DEQ and OHA developed a guidance manual to assist local communities in following these rules and preparing a drinking water protection plan. The Oregon Wellhead Protection Program Guidance Manual (ODEQ/OHA, 1996) was utilized in the process of creating the Creswell Drinking Water Protection Plan. The creation of a Drinking Water Protection Plan is voluntary for Oregon communities. The benefits of having a drinking water protection plan in place and implementing the Plan as prescribed are many. The Plan addresses past, current, and future potential contaminant sources. It suggests ways to resolve these problems, therefore protecting the health of the consumers. Contamination reduction and avoidance also reduces the costs and difficulties of treating water at the water treatment plant. The creation and implementation of the Plan may assist the City of Creswell in obtaining future funding and reducing monitoring needs and costs. Purpose The overriding purpose of this project is to develop a drinking water protection plan that supports high quality and quantity of water that benefits the health and economic viability of the community. There are seven primary goals of this project: 1. Involve the public in the creation of a Drinking Water Protection Plan for their community. 5 2. Enhance the SWA inventory by collecting existing information not included in the Source Water Assessment and utilizing the diverse local knowledge of citizens. 3. Refine the SWA sensitive areas with GIS and LIDAR data and additional geologic information. 4. Reassess the susceptibility analysis by overlaying the refined sensitive

A Source Water Assessment for the groundwater portion of your water supply will be addressed in a separate report. The assessment was prepared under the requirements and guidance of the Federal Safe Drinking Water Act and the US Environmental Protection Agency, as well as a detailed Source Water Assessment Plan developed by a statewide citizen's advisory committee here in Oregon over the past two years. The Department of Environmental Quality (DEQ) and the Oregon Health Division (OHD) are conducting the assessments for all public water systems in Oregon. The purpose is to provide information so that the public water system staff/operator, consumers, and community citizens can begin developing strategies to protect your source of drinking water. As you know, the 1996 Amendments to the Safe Drinking Water Act requires Consumer ConfidenceReports (CCR) by community water systems.
