AGENDA ITEM 3 General Citizen Participation Richard Tocher, 3960 Greenbriar Blvd., Boulder 80305, asked Ned Williams if any security measures had been taken to protect Boulder's drinking water. Williams said that security measures are in place but he said it wouldn't be appropriate to discuss specifics of those measures in public. Tocher also asked several questions related to the Marshall Landfill Closure Plan during the time when Floyd Bebler presented that issue. General Citizen Participation was closed. Water Resources Advisory Board Full Minutes December 17, 2001 Page I AGENDA ITEM 4 Staff presentation and discussion on the Marshall/Boulder Landfill Groundwater Treatment Facility EPA Five-Year Review and proposed closure study. Floyd Bebler gave the background on the Marshall/Boulder Landfill. The EPA named both BFI, Inc. and the city of Boulder as responsible parties for remediation of contamination. The site was added to the CERCLA National Priorities List in 1983 and in 1986 a Record of Decision for a remedial action was issued that included groundwater collection and treatment. Construction of a treatment system was completed in 1993. Groundwater is collected from 35 wells, a collection trench, and an on-site french drain system. Collected water is treated at an on-site treatment facility, financed by both the city of Boulder and BFI. The city pays approximately $195K (30% of the total budget) per year to operate the facility and perform required sampling and analysis. The treatment system is designed to remove metals and volatile organic compounds. Typically, concentration of parameters influent to the treatment plant are below treatment levels, except for iron and manganese, which are naturally high in that area. Effluent from the treatment system is discharged to Cowdrey drainage, which drives the treatment standards. Cowdrey Drainage potentially flows into South Boulder Creek; however, Cowdrey Drainage generally doesn't reach SBC. BFI and the city are proposing to the EPA to match discharge standards for iron and manganese to naturally occurring groundwater concentrations and continue long-term monitoring of groundwater quality. This would allow transfer to a standby status with eventual decommissioning of the plant. The proposal also includes long-term maintenance of the cap over the landfill. BFI sent a request for proposals to four subcontractors to prepare closure plans. The purpose of the RFP was to obtain proposals for development of a long-term monitoring plan, groundwater treatment facility shutdown plan and a site operation, maintenance and inspection program. Upon selection of a consultant the staff estimate is that the closure plan will be submitted to the EPA within 4-6 months. The closure plan should reduce costs to the city by approximately 25%. There will still be a substantial amount of sampling and analysis required. The EPA performed two five-year reviews on the site and has generally been pleased with the actions taken at the site. Given the low influent levels of constituents of concern, the EPA has begun entertaining other options for site management. Water Resources Advisory Board Full Minutes December 17, 2001 Page 2 AGENDA ITEM 5 Staff presentation and discussion about the January 29, 2002 City Council Study Session concerning modifications to Boulder's Floodplain Management Program. Ned Williams discussed the upcoming City Council study session that will evaluate what kinds of programmatic changes the city should consider in assessing its floodplain management program. Williams said these program changes have been discussed the program with city staff and members of the Independent Review Panel. Alan Taylor is taking the lead on evaluation of the program. Williams said the program would most likely be based on increased citizen education and individual flood control programs (by household) with a focus on floodplain management rather than on capital projects aimed to control floods. The staff will urge the City Council to define critical facilities, such as hospitals, elder care facilities and child care facilities that are prohibited from construction within floodplains. Williams said that there is a national trend toward floodplain management rather than flood control. The focus will be on city policies only and on land that may be annexed into the city. There was some limited discussion about the lawsuit involving the University of Colorado and Boulder County. The university abides by state regulations and does not recognize the city's defined high hazard zones and the regulations associated with that zone. Williams said that the focus nationally is for less containment with more emphasis on property by property flood protection, increased homeowner awareness and improved flood insurance. The focus doesn't preclude capital improvements but, in general, the strategy of floodwater containment is gone. The study session will include recommendations for possible financial contributions to homeowners that take steps toward reducing life-safety issues and that provide damage minimization. Jeannette Hillery commented that there are thousands of homeowners along South Boulder Creek that want information about what to do during a flood and are working toward individual containment methods. AGENDA ITEM 6 A. Matters from the Board Cal Youngberg asked if there would be a site review for the 631d St. facility biosolids program. Williams said that annexation is expected within 6 months and the scope of work is still in progress. The city has met with the Boulder Historical Society and the town of Valmont to discuss their concerns about the biosolids program. Floyd Bebler commented that there has not been much public comment about the issue yet. Bebler also announced that Paul Heppler, the Water Resources Advisory Board Full Minutes December 17, 2001 Page 3 staff member that runs the biosolids program for the city, is leaving the city to work for the state of Colorado. Gil Barth discussed the Greenways Advisory Committee meeting that he attended and informed the board that the Greenways Master Plan had been revised. Bob Fiehwe said that he was contacted by a member of the Environmental Advisory Board about the fluoride in drinking water issue. He said that the WRAB would probably have to revisit the issue in the future because the EAB is still discussing it. Vicki Naber asked about eco-passes for board members. Robin Madel said she would check into the status of the passes. B. Matters from the Staff Ned Williams discussed the vote by the Erie Board of Trustees that called for a citizen initiative of fluoridation of drinking water if the town of Erie is to fluoridate its water. Williams also pointed out that Dannon now makes bottled water with fluoride in it. Williams updated the WRAB on Lakewood pipeline. A construction contract was awarded to Bernard Construction Company and construction will begin in April or May. Also, the city will be going to the City Council about condemnation of 2 properties for which they could not obtain easements. Williams said that the 2002 budget with the new utility rate changes was approved and will go into effect on 1/1/02. Williams discussed the advisory group associated with South Boulder Creek. The group has evolved into a hydrology advisory panel for SBC and may become an advisory panel for the entire city. Williams discussed the memorandum of understanding signed by the city and the University of Colorado regarding development of Williams Village. Construction of student housing will begin in 2002. The WRAB requested a site visit with a CU official. Williams mentioned that advisory board recruitment would take place in January. He mentioned that Cal Youngberg's term is ending. Youngberg said that he would apply for re-nomination. Williams discussed the status of Valmont Park. The grading work has been completed. The next issue is stream flow maintenance. The city is negotiating a deal with the White Rock Ditch Company to keep some stream flow in the channel. The issues associated with the Cline property were resolved. Williams said that work on the Barker Management Plan is progressing and the WRAB will get an update in March. Water Resources Advisory Board Full Minutes December 17, 2001 Page 4 The January and February meetings fall on city holidays and Williams requested rescheduling the meeting at a time that is in-between the 2 dates. The WRAB chose January 28 as the meeting date. The next meeting after that will be on March 18. Williams gave an update on relocation of the effluent line at the WWTP. He said all of the permit applications will be completed by the deadline of December 31, 2001 and the town of Lafayette will take the lead in the County 1041 application.
