for this project will be similar in design and operation as the approved Ronald Class A Reclaimed Water Facility. The Class A Reclaimed Water Facility will be approved through the Washington State Department of Health and permitted by the Washington State Department of Ecology. The existing community drain fields may be used within the design of the Class A Reclaimed Water Facility. This reclaimed water facility will be operated by a qualified operating entity and will serve the property included within this proposal. That service area will be compatible with the service area of LCU, Inc.'s Group A Water System that will be also serving the property that this proposal covers. This facility will take domestic sewage from the project and treat it to a level that meets or exceeds Class "A" Reclaimed Water requirements. These requirements are the highest standards recognized by Department of Health and Department of Ecology and allow that water to be put to beneficial use. Class "A" reclaimed water is suitable for many beneficial uses including, but not limited to, irrigation of food and non-food crops, landscape irrigation, impoundments for landscape and recreational uses, construction water, fire fighting/protection, aquifer recharge, and stream enhancement. The standards for Class "A" Reclaimed Water established by the Department of Health and the Department of Ecology require treatment and disinfection to a level that is far above what conventional wastewater treatment facilities are required to provide. The standards also require automated alarms, redundancy of treatment units, emergency storage, and stringent operator training and certification to meet reliability criteria. Elimination of septic systems and treatment of wastewater from the project to these high standards provides for increased benefit to Public Health far above that which is seen in conventional wastewater treatment plants or soil based treatment of septic systems. Initially the early phases of the development will be served by community septic systems. This type of treatment will continue until the volume of effluent generated by the development reaches an adequate level (approximately 10,000 gallons per day) to sustain the operation of the Class A Reclaimed Water Facilities. As the volume of effluent approaches the needed flows to operate the Class A Reclaimed Water Facility the facility will be designed and constructed and take over the treatment of the effluent generated by the proposed development. The system will be sized to adequately treat and reclaim the domestic sewage from the residences and facilities served by the Group A Water system that would serve this property. Construction of this reclaimed water facility will include a central treatment facility, underground collection and distribution systems, and storage facilities. The system will continue to use the community drain fields as an alternate location to dispose of the reclaimed water as allowed by the Class A Reclaimed Water plan for this project. C. Water Runoff (including storm water): 1.) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. A stormwater permit will be obtained from the Washington State Department of Ecology and a stormwater pollution prevention plan will be developed implementing measures to reduce and control stormwater onsite. 2.) Could waste materials enter ground or surface waters? If so, generally describe. Waste materials, excluding sewage, are not expected to enter the ground or surface waters. (See questions above in reference to sewage and septic uses.)
