Review and Comment on Hammond /Roberts Wastewater Facility - Fodroczi distributed copies of a handout outlining Review Points of Concern for the Plan Amendment. There were changes in the proposed treatment system and the site of the absorption pond. The staff made individual department reviews but has not had an opportunity to finalize a group review. The review is a summary of what is identified as issues and concerns. A report was received from NCRS staff on soil issues. Staff will do additional work this week and finalize next week for the PZP Committee on July 22 " Final comments must be submitted by July 25 Fodroczi also distributed a set of three maps showing the revised treatment plant site plan, the pipeline route and layout of the Miller site absorption ponds. Fodroczi explained the change from the proposed "Gillis" site at Hammond for the treated effluent to the now proposed "Miller" site south of Highway TT at Roberts. The DNR determined that the original site was marginally acceptable. The Commission is proposing to purchase the Miller site. The Commission is also proposing to pipe relatively untreated effluent (screened for solids and grit) from the Hammond plant along Highway TT to an expanded Roberts wastewater treatment plant. The new treatment would be a combination of biologic processing and microfiltration to produce a substantially improved effluent, an upgrade of the earlier plan. All treatment is planned for the expanded and upgraded Roberts facility. The plan shows two output pipelines, one directly east to the new absorption pond and the other to Twin Lakes, which would maintain water levels in the lakes and provide shoreline stabilization. Fodroczi explained that the cleaner effluent could be used or reclaimed for agricultural, industrial and commercial purposes. No specific uses are planned, however, the possibility of County Concrete using this effluent in its concrete production was considered. This could reduce the amount of draw from the aquifer. Wittmer stated that County Concrete presently uses 400,000 gallons of water per workday. Roberts presently treats 55,000 gallons per day and Hammond presently treats 85,000 gallons per day. Fodroczi stated that additional disinfection with ultraviolet light is also proposed as a final treatment. Changes from the original plan concerning environmental conditions with this new treatment system are also addressed in this plan. A new total cost estimate is approximately $10 } million, with phase one being $8.5 million. The proposed ponds are in the Kinnickinnic watershed. Fodroczi explained that the new treatment process with upgraded effluent is new technology that has been used in other states, and the DNR is open to consider it as part of this pilot area along the I -94 corridor. Committee members were concerned with what will happen to the residue /sludge after treatment. Fodroczi stated that the conclusion emphasizes that the Miller site is a much more acceptable location in terms of soil structure, depth of bedrock and groundwater. The site, the treatment and cost of this plan are all better than the original facility plan. Fodroczi noted the differences between the comments on the original facility plan and how this might alter or generate comments. He noted that the projections used in the amended plan are the same as those used in the original plan, specifically a projected population for the two communities of over 11,000 in 2025. Fodroczi noted that the original plan was designed to accept septage, but the amended plan does not due to extra costs and uncertain revenues. Since there are no present regulations requiring haulers to deliver septage to such treatment sites, the necessary revenues to cover costs for including this in the plan cannot be assured. Committee discussed the issue of regulating the spreading of septage on fields. Fodroczi commented on the points of concern by the staff and Committee members offered comments and suggestions. This discussion focused on various options for reuse or reclamation of the treated effluent and a number of concerns Committee members had about the pipeline of untreated effluent. Fodroczi stated that there has been no discussion with the Highway Department regarding installing the line in right -of -ways. The Land and Water Department Staff found no shoreline stabilization needs in Twin Lakes and questioned the reason for including this in the plan. Malick stated that natural fluctuation of water levels could be beneficial as it allows natural vegetation to grow at lower levels. Land and Water Staff also identified some concerns regarding groundwater modeling. A hydrogeologist did a presentation at the public hearing and talked about mounding effluent after it goes through absorption ponds, interaction with groundwater, how it might spread, and effects on public and private water supplies. The staff is also concerned about what is not in the report about soil structures of the site and percolation of the effluent. Wittmer has NRCS comments regarding these issues. Significant issues are not addressed in the plan. Since monitoring wells were used on the site for only 24 hours, the data included in the report was limited. The idea of having a separate groundwater discharge near Hammond as an alternate was discussed. Malick suggested laying a dry line that could subsequently be used if problems were found in the streams or wells in the Hammond area that were affected by not having groundwater recharged in that vicinity. The Committee also discussed both Villages doing the same type of treatment and pumping only the treated effluent through a pipeline. It would also allow the possibility that farms along the route could tap into that line for agricultural use. 2 • , R The staff will prepare a final draft of comments after Heise returns from vacation on July 21 The Committees agreed to meet on Wednesday, July 23 at 7:00 p.m. in Baldwin to review final comments. COUNTY SURVEYOR UPDATE - Fodroczi stated that he, Tim Ramberg, Brian Halling, Steve Fisher, Chuck Whiting and Rich Loney met on July 11 and reviewed recent budget information and a framework for the work plan showing general categories of activity. Halling is working on determining additional workload and financial needs. He is meeting with individual departments that are looking for Surveyor assistance to help finalize the report. The work plan will show different scenarios, one with the resources committed at this time and one that we should do with additional costs. The plan will be completed and ready to present to the Committee on July 22 Budgets must be ready by mid - August. The meeting adjourned on an Anderson/Burri motion at 10:42 a.m. Respectfully submitted Judy Olson, ecording Secretary G�f.Qi Lois Burri, Secretary 3
