The Council met in a workshop session at 6:00 p.m. with Mayor Kirksey presiding to discuss Water Master Plan issues. ROLL CALL. Mayor Councilor Councilor Councilor Councilor Councilor Councilor Kirksey Chadwick Figley Hagenauer Jennings Pugh Sifuentez Present Present Absent Present Present Present Present (6:06 pm) Staff Present: City Administrator Childs, Public Works Director Tiwari, Public Works Manager Rohman, Water Superintendent Schooler, City Recorder Tennant Also Present: Preston Tack, Ron Lilienthal, and Charlotte Hiller 0052 Public Works Manager Rohman provided an overview of the Water Master Plan to update the Council on the status of this project along with discussion on issues to be addressed by the Water Master Plan Committee. He stated that reasons for completing the Plan include the need to satisfY public requirements, comply with changing water regulations, provide reliable fIre protection to our community, and develop a plan that will provide sound planning as the City grows which is economically feasible. He stated that the Plan was originally started in 1996 and a workshop and public hearing were held to obtain citizen input on the proposed plan. On December 5, 1996, an Open House was held to give the residents of the City an opportunity to participate in the development of the master plan. Following the open house, a meeting was held with representatives from Senior Estates on January 28, 1997 to receive additional comments on the plan. The City contracted with HDR Engineering to assist in the development of the Water Master Plan. The major recommendations were to I) prepare a well-head protection program, 2) insure adequate water supply, 3) treat the water supply to remove iron and manganese and provide flexibility in meeting changing regulations, and 4) provide additional storage of water. The well-head protection program is required as part of the Safe Water Drinking Act, and Oregon has a voluntary program approved by the EP A. When a well-head protection program is developed, it is certifIed by DEQ and the Health Divison. A benefIt in having a certifIed program is that it complies with the LCDC goal 5 which is national resources (groundwater). Within the guidance manual developed by DEQ and the Health Division, they recommend that a committee be appointed to develop the well-head protection program.

Preston Tack questioned how the City's well-head protection program would fit in with the County program. Public Works Manager Rohman stated that the MWV Council of Governments has done work for some small communities in starting the basics of well-head protection programs but he is not aware of what, if anything, the County is doing in this area. Administrator Childs stated that it is his understanding that the County is developing a master plan but he did not think that it was specific in the area of well-head protection. Public Works Manager Rohman stated that additional wells may be required in order to insure adequate water supply based on growth demands. In regards to water treatment, Public Works Manager Rohman stated that this was a major recommendation to remove iron and manganese which are the two minerals that cause most of the aesthetic problems. These two minerals are considered as secondary water standards and are not related to safety. They do cause the staining of fixtures and clothing, and an odor. A treatment process was being looked at that would remove the iron and manganese without adding chlorine to the water supply. However, the Groundwater Disinfection Rule may ultimately mandate that the City disinfect the water. The standard for arsenic has not been established at this time. The City is below the current level but some method of removing arsenic may have to be implemented in the future. One of the benefits of removing iron and manganese is that it may also reduce the arsenic level to below the potential EP A level. Lastly, additional water storage tanks are needed to meet peak demands and insure an adequate water supply for firefighting purposes. Currently, the City is working with the State Water Resources Department for the approval of a well field concept. The City has developed various water rights for some of our own wells which are no longer used and water rights for wells drilled recently. The City is proposing to use the entire Urban Growth Boundary as a well field and the water rights of the various wells would be applied over the entire City to serve current and future needs. Based on current needs, the City will need to add a new well in the near future to make sure there is a sufficient supply of water during the summer months to meet the maximum daily needs. In regards to federal regulations, a Consumer Confidence Report will be implemented in 1999 which will require the City to publish an annual notice to all customers to give them a status report on the City's water system. The arsenic rule has not been set yet and the EP A may be issuing the proposed final rule in 1999 with final rules to become effective in 200 I. It is anticipated that the proposed final rule for Groundwater Disinfection will be in 1999 with the final rule issued in 200 I. This rule will direct groundwater systems, including the distribution system, to disinfect and there will probably be provisions written into the rule for variances to be granted. Finally, a new contaminant listing will be issued by the EP A every 3 years and limits will be set for those that are considered as health risks. It is unknown at this time if there will be any effect on the City's water supply and subsequent treatment. Each well will draw its water from a specific area and a contaminant in one well Page 2 - Council Workshop Minutes, December IS, 1997 .. ...-.._.~..-_._--_._--_._~-- ....-.~.T COUNCIL WORKSHOP MEETING MINUTES December 15, 1997 TAPE READING may not show up in any of the other wells. The Water Master Plan has been reviewed by the Oregon Health Division and they have indicated to the City that, once submitted, they would approve the document. He reviewed the implementation schedule which includes plan adoption and State approval in 1998 , working on a well-head protection program over the next two years, a water rate study in late 1998/early 1999, doing a preliminary engineering work on the treatment systems required in 1999, making funding decisions in early 2000, proceeding with the design and bid process in 2001, and construction in late 200llearly 2002. At a prior hearing, Mr. Tack had recommended that the plan include an option to build 3 neighborhood treatment plants to provide treatment over a longer time frame and postponing the Phase II work. HDR Engineering evaluated this suggestion and it was found that costs were slightly more but it is something that can be looked at since it would potentially postpone the implementation of Phase II and would also potentially allow the City to treat water during peak demand periods and more capacity for the treatment operation. The engineers had also looked at placing a treatment site at each well but this option was not cost effective. Staffis recommending that action be taken to (I) begin the process of developing an additional water well, (2) develop a well-head protection program and appointing a committee to work on this project, and (3) the remaining plan be implemented as proposed in the schedule. Barbara Lucas questioned if the City has the authority to drill a new water well at this time. Public Works Manager Rohman stated that the City would have to obtain approval from the State Water Resources Department, however, the City does have the water rights. The estimated cost to drill the well, construct the wellhouse, and make it fully operational is between $250,000 and $300,000. Councilor Jennings stated the information presented at this workshop has given the Council and Task Force an excellent overview of what needs to be accomplished. Mayor Kirksey stated that the Task Force will work with staff to meet the time frames that have been laid out and this Committee should be working with staff to develop the wellhead protection program. Councilor Jennings also stated that he would also like to see this Committee work on the rate study since the work done by the Wastewater Committee proved to be very helpful when finalizing sewer rates. Mayor Kirksey stated that she would be making formal appointments to the Water Master Plan Committee at the special Council meeting following this workshop.
