There was none. Public Partici ation was closed. _ Agenda Item 4- Presentation for parting cB~air Ken V6'ilson Williams presented Wilson with a plaque and cake for his commitment to the WRAB over the past five years. Agenda Item 5- Fina1 recommendation on the Wastewater Treatment Master Plan Eazley and Harberg presented the Wastewater Treatment Master Plan and asked for the Board to make a final recommendation to Ciry Council. WRAB questions and comment: • Byers: On figure 18, I had asked for labels on the "y" axis. Can we add arrows or something to make it more instructive? Earley: I will try to revise it again. • Byers: Did the CDPHE change the ammonia standards? W iIl those standards get included in the new permit process? Linenfelser: We dodt think the new standazds will be implemented in the next permit cycle. • Miller: Do you know if the costs for treatment relate to flow quantity more so than population increases/decreases? Earley: The plant is presentty being expanded to account for the hydraulic loading (flows) that are anticipated for build-out conditions. The stren h of the waste (pollutant load based on population) does not decrease when the flows decrease. Therefore, the treahnent costs should not change much as either the flows or population change, except for the power (electricity) costs to operate some pumps. • Miller: The wrrent decrease in flow has understandably not been included, but if this level were to continue, is there a way to factor that in? Earley: We aze not factoring that in at the present time. While there has been a decrease in flows recently because of water conservation efforts and lower ground-water levels, our long-range planning effort uses a conservative approach that anticipates flows to gradually increase back to more his[orical levels, at least on a cyclical basis. • Knopf: How will the Transit Village affect this? Earley: [t will increase our flows, but flows will still be within the hydraulic loading we can handle. • Byers: Will annexations make a difference in flow levels? Earley: There are some small properties that may annex and increase flows, but these areas are part of our anticipated service area. Public Hearing: No public comments. Motion: Wilson moves that the Water Resources Advisory Board (VVRAB) approve the presented draft of the Wastewater Treatment Master Plan and to forward this recammendation to Cit WRAB Summary Mazch 19, 2007 Page No. 1 Council (the presented draft has mislabeled the date). Seconded: Byers Vote: 5-0, Passed Agenda Item 6- Update on the evaluation of source water protection for Boulder Reservoir, including additional treatment and the Carter Lake Pipeline Project Noble, along with consultant Chris Tadanier with Black & Veatch, presented on the evaluation of source water protection for Boulder Reservoir, including additional treatment and the Carter Lake Pipeline Project. WRAB Discussion: • Wilson: Do we own storage in Carter Lake? Williams: We do not own storage, but we can order water from there. The only reason we aze limited today is because winter conditions prohibit the operation of Boulder Feeder Canal. • Byers: What would the CEAP include? Improvements, new projects? Harberg: All of those and everything, including altematives. • Knopf: What is the projected rate increase? Noble: Inflation rate increase in 2008-2010 is at 3%. More information is in the memo. Knopf: Can we get this kind of information for wastewater? • Byers: W ill money from the settlement with Xcel on the RECs go to the general fund or utilities? Williams: I do not think that money is part of the settlement. Also, it has not yet been determined how to use the credits for the ciry's RECs. • Byers: Are some concerns that we have driving or motivating entities (such as Left Hand) for this as well? Tadanier: Yes. Winter water is their driving issue. • Miller: Did any of the altematives look at the affect the ciry or county could have on land uses such that land use cegulations could prevent the degradation? Struthers: The city is currently trying to work with Northern on this, although Northem is hesitant to control land use or outfalls. It would be on the city's shoulders to secure approval to change outfalls. • DiNatale: The studies ue very biased. You aze assuming there will be no change in Carter Lake water qualiry. You are assuming there will be no change in future drinking water requirements. You assume there will be no major renovations to the Boulder Reservoir treatment plant within the 20-year planning period. This study has a pre-determined outcome. It lacks credibility. I dodt disagree with the conclusion, just the way we are getting there. • DiNatale: Did you look at the ulha-filtration membrane processes? Tadanier: No, because it provides an ultimate barrier for bacteria but only a partial barrier for viruses. DiNatale: I disagree. Uitra-filtration with chlorination will meet the city's virus treatment goals. • DiNatale: I am surprised you diddt work with policy-makers on the performance criteria and weighting. . • Miller: Can you double check your cost estimate numbers for granular activated carbon as well as the spike in costs related to steel pipe in the Pipeline altemative? Tadanier: We will look into this. • DiNatale: I would like to see the integration of this study with the source water strategic plan to see how this relates. Harberg: We are running behind schedule on the source water strategic plan and the Boulder Reservoir project will need to move forward before then for 2008 budgeting purposes. • Wilson: This study has come forward in a good direction, but you are having a hard time selling it. DiNatale: I would like to see what the long-term (20 years) plans are for managing the Boulder Reservoir WTP. Harberg: Staff will use the comments WRAB has given during this meeting to improve our reporUanalysis, and then return to WRAB in the future for this project. Agenda Item 7- Matters From Staff- • South Boulder Creek Flood Study will be presented to Planning Boazd on Thursday. Matters from Board - ~ Byers: How much did the double-billing (sending two bills in January) cost us? Williams: I do no[ know. WRAB Summary March 19, 2007 Page No. 2 • DiNatale: I got a call from a citizen who said he had to give away his Anderson Ditch water righu in order to get a building permit. Williams: I am aware of this issue and the city and property owner are curcently working on a mutually agreeable solution. • Byers: What is happening with the South Platte River Wells' case? Williams: It is in recess now, but it is still ongoing and will resume later in Mazch. • Byers: Where is Valmont Butte project with respect to the Trust for Public Land (TPL) acquisition? Williams: The city is waiting for the TPL to submit a proposal and proceed with fund-raising. Agenda Item 8- Discussion of schedule tor future meetings.
