HomeMy WebLinkAboutItem 06.iMarch 16, 2011 Proposed Action Staff recommends adoption of the following motion: Move to approve the proposal from Barr Engineering Company to prepare Amendments to Parts 1 and 2 of the Wellhead and Source Water Protection Plan (WHPP). Overview Kei h H. Nelson City Engineer Item No. MARCH 21, 2011 CITY COUNCIL AGENDA ITEM APPROVE PROPOSAL FROM BARR ENGINEERING COMPANY TO PREPARE AMENDMENTS TO PARTS 1 AND 2 OF THE WELLHEAD AND SOURCE WATER PROTECTION PLAN (WHPP) The Minnesota Department of Health (MDH) notified the City that, in accordance with the Wellhead Protection Rules, the City must amend its WHPP eight years after the date the plan was last approved, which was April 30, 2004. The City must begin the amendment process by April 30, 2011, and complete the process by April 30, 2014. Since the last plan approval, Wells 17, 18, and 19 have been added to the public water supply. Attached is a proposal from Barr Engineering Company providing the scope of the work and cost estimate to complete the amendments to Parts 1 and 2 of the WHPP. Estimated cost for Part 1 of the WHPP is $11,970, with the possibility of additional project costs in the range of $500 to $4,000. Estimated cost for completion of Part 2 of the WHPP is up to $15,000 to $23,000. Included in the proposal is a Work Plan with projected completion dates. Two years seems like a long time, but this is a lengthy process with several agency review and comment periods. $50,000 was budgeted from the Water Operating Fund. Primary Issues to Consider None.

The WI1.P rule states (Minnesota Rules, part 4720.5570, subpart 3) that a public water supplier must begin the process of reviewing and amending a WI P plan eight years after the date of the last approval of a plan by the-. Minnesota Department of Health (MDH), which was April 30, 2004. Because the city of Lakeville has added three new wells to their public water supply since the last approval of your plan, the city will begin amending their WHP plan by April 30, 2011, and completing it by April 30, 2014. Starting one year earlier - will give the city sufficient time to incorporate their new wells into the plan and com- plete their amendment. Because the city of Lakeville has completed and submitted to MDH copies of their evaluations on a yearly basis, the city has already met the rule requirement of submitting an evaluation at the Scoping 1 meeting for the plan amendment (Minnesota Rules, part 4720.5270, subpart 5). MDH is committed to providing you with a high level of assistance and technical support m this endeavor. 1 have been assigned as a primary contact and look forward to working with you to amend your WHP plan. If you have any questions, please contact me at (320) 223 -7322.

As you know, Part 1 of the WHPP includes delineations of the Wellhead Protection Area (WHPA) and the Drinking Water Supply Management Area (DWSMA), well and aquifer vulnerability assessments, and associated reporting requirements. In Part 2 of the WHPP, potential contaminant sources within the DWSMA are identified and management strategies are developed for protecting the aquifer from which the City obtains its drinking water (i.e., the Source Water Aquifer) from contaminants associated with these potential contaminant sources. Accordingly, the objective of the work is to complete Parts 1 and 2 of the WHPP in a manner that meets the requirements of the Minnesota Wellhead Protection Rules. We are committed to providing the City of Lakeville with a high level of service and value in wellhead protection. Our approach is designed to help you protect your drinking water supply and meet the State requirements for wellhead protection plans in a cost - effective manner. The following proposal is based on our review of the November 1, 2010 letter you received from the Minnesota Department of Health (MDH), a telephone discussion John Greer of Barr had with Steve Robertson of the MDH regarding amendment of Part 1 of the City's W1IPP, and our experience with developing WHPPs and amendments to WHPPs. Project Scope and Assumptions We have reviewed the November 1, 2010 letter to you from Karen Voz of the Minnesota Depart- ment of Health (MDI1) notifying the City that the City's existing WIIPP must be amended. Per the November 1, 2010 Letter from MDH, the City must begin the process of amending the WHPP by April 30, 2011 . and complete the process by April 30, 2014. CITY OF LAK VILf_.E Mr. Keith Nelson, PE February 11, 2011 Page 2 WHPP Part I The delineation of WHPAs must be done according to the requirements of Minnesota Rules (MR) 4720.5100 to 4720.5590 (the Wellhead Protection Rules). The first step in amending Part 1 of the City's WHPP is Scoping Meeting No. 1, which is run by MDH staff. Based on the November 1, 2010 letter from M.D.H and our phone conversation with you on January 21, 2011, it is our understanding that the MDH has not yet scheduled Scoping Meeting No. 1. At the Scoping Meeting, MDH staff will discuss the criteria required to be used to delineate a WHPA and DWSMA, the data elements that must be addressed, and the administrative and procedural steps in the process. Because this meeting has not yet occurred the total scope of services required to meet MD.II requirements is not defined. Our proposal will provide you with a base cost to perform those tasks that are required in all plans but will not include costs for some of any project - specific items identified at the Scoping Meeting that will be required for your plan. Following Scoping Meeting No. 1, additional milestones for the Part 1 amendment process include: • Notice of Intent to Amend to Local Units of Government. The City is required to notify surrounding local units of government of its intent to amend the WHPP, This notification should go to cities, townships, and watershed districts whose jurisdictions are in the vicinity of Lakeville as well as Dakota County, and Metropolitan Council. Attached to this proposal is a Notice of Intent to Amend that you could use to meet this requirement. • Pre- Delineation Meeting. The MDH technical reviewer will meet with the City's technical consultant to discuss the planned approach for delineating the WHPA and DWSMA. The MDI -I technical reviewer fir Part I of Lakevi.11e's WHPP will be Steve Robertson. • Review of the draft Part 1 Amendment by MDH. Typically, the MDH technical reviewer will review a draft version of the Part 1 Amendment and provide comments regarding modifications they want made to the Amendment before it is submitted for final approvaL Our experience has been that this approach streamlines the review and approval process. • Submittal of the final Part 1 Amendment to MDH for° approval. • Copy of approved areas to Local Units of Government. Within 30 days of receiving approval of the Part 1 Amendment, the City must submit a copy of the delineated WHPA, DWSMA, and vulnerability assessments to local units of government whose jurisdictions are wholly or partially within the delineated areas. • Public Information Meeting. Within 60 days of receiving approval of the Part 1 Amendment, the City must hold a public information meeting for the general public at which the approved WHPA, DWSMA, and the vulnerability assessments are available for review by the public. Our attached cost estimate for amending Part 1 of the WHPP is based on the following assumptions: • Barr staff will attend. Scoping Meeting No. I. Within 30 days of the Scoping Meeting, the MDH will send the City of Lakeville a Scoping .Decision Notice that summarizes discussions at the meeting and identifies requirements for the Part 1 WHPP. The requirements specified in the Scoping Decision Notice will fully clarify the scope of work needed to meet MDH requirements. Following the meeting we will submit to the City of Lakeville a modified Mr. Keith Nelson, P1', February 1 1 , 2 0 1 1 Page 3 scope and budget document that accounts for any additional tasks identified by the MDH that will be required for plan approval. A The City of Lakeville will send the required Notification of .Intent to prepare a WHPP to surrounding local units of government. We have attached a draft Notification of Intent for your use, if you so choose. A The Wellhead Protection Rules require that data from aquifer tests be used to determine aquifer transmissivity for use in developing Part 1 of the WHPP. Since this project is to amend an existing WHPP, we have assumed that no pumping test will need to be performed as part of this work. Rather existing data from tests previously conducted in one or more of the City's wells can be used to meet this requirement. A The MDH requires that WHPA delineations include both porous media and fractured media groundwater flow evaluations in settings where groundwater flow through factures may be important. For example, groundwater flow through fractures is the main flow path in the Prairie du Chien aquifer (composed of limestone/dolomite) while groundwater flow through pore spaces between sand grains is the main flow path in the Jordan Sandstone. Based on 1) our telephone discussion with you, 2) the fact that Lakeville wells pump from the Prairie du Chien aquifer, and 3) our experience with WHPA delineations for other cities with wells open to the Prairie du Chien aquifer, we have assumed that both porous media and fractured media groundwater flow evaluations will be required. Please note that a fractured media flow evaluation was not required for the original Part 1 WI -1PP. You should be aware that this will likely significantly increase the size of your WHPA and DWSMA. A Techniques described in the MDH document "Guidance for Delineating Wellhead Protection Areas in Fractured and Solution- Weathered Bedrock in Minnesota" will be used to perform the fractured media groundwater flow evaluations. A The MPCA's Metropolitan Area Groundwater Model (Metro .Model 1) was used to do the original Lakeville WHPA delineations. During the preparation of this proposal we discussed the amendment of Part 1 of Lakeville's WHPP with Steve .Robertson of the MDH, Mr. Robertson stated that the MDI-I considers Metro Model 1 to no lon1er be appropriate for use in WHPA delineations because of the way the Prairie du Chien and. Jordan aquifers are simulated in that model. As a result, significant work would be required to modify Metro Model 1 so that it would be acceptable to the MDH for WHPA delineations, Barr Engineering constructed a new groundwater model for the Twin Cities metropolitan area (Metro Model 2) for Metropolitan Council Environmental services in 2008. We have used Metro Model 2 as the starting point for several recent Part 1 WHPPs. During our discussion with Steve Robertson, he stated that Metro Model 2 would be an appropriate model for performing the porous media groundwater flow portion of the WHPA delineation. We have assumed that it will not be necessary to modify Metro Model 2 to more accurately represent geologic details in the vicinity of Lakeville or to adjust hydraulic conductivity of the Prairie du Chien Group and Jordan Sandstone aquifers in the vicinity of Lakeville. We have assumed that MDI-1 will require that the model grid be refined in the vicinity of the Lakeville wells. This grid refinement may require some adjustment of hydraulic conductivity zone boundaries so that aquifer extents are accurately represented in the model. After completing the grid Mr. Keith Nelson, PE February 11, 2011 Page 4 refinement, the updated model will be used for the porous media groundwater flow evaluation. Based on our experience with using groundwater models based on Metro Model 2 for WHPA delineations, we have also assumed that the model we propose to use is sufficiently calibrated for the purposes of this project and that no further calibration will be necessary. y' Based on our experience with preparing Part 1 W.HPPs, we have assumed that model sensitivity (a.k.a., uncertainty) analysis will be required by MDH. This requirement will be verified at the Pre - Delineation Meeting. • In order to eliminate costs associated with travel time we are assuming that the required Pre - Delineation meeting with MDH staff will be held in Barr's office and will last one hour. • The MDH will provide well vulnerability assessments for the Lakeville water supply wells. ➢ After completing the WHPA delineations, we will delineate the DWSMA. In order to save costs we have assumed that the DWSMA delineation will be done using transportation corridors, political boundaries, and public land survey section/subsection (e.g., quarter - section) boundaries. Property parcels could be used to delineate the DWSMA and could result in a somewhat smaller management area. If you prefer to use parcel boundaries for DWSMA delineation we will assess the additional amount of work involved and provide you with a revision to our costs. • Aquifer vulnerability will be assessed for the DWSMA using existing geologic information such as the county geologic atlas and /or well logs stored in the Minnesota Geological Survey's County Well Index (CWI). Steve Robertson of the M. DH indicated that while the Dakota County Geologic Atlas includes a pollution sensitivity map for the Prairie du Chien /Jordan the fact that the Atlas is nearly 20 years old will require that it be evaluated against newer information to determine if it is still accurate. Our costs assume that the county atlas information will be of acceptable accuracy. If it is determined to be necessary to use other information for the aquifer vulnerability assessment we will provide you with a revions to our costs. The 2002 Lakeville Part 1 WHPP indicates that areas of high aquifer vulnerability exist within the current Lakeville DWSMA. Since the original Lakeville Part 1 WHPP was completed, MDH has begun requiring that surface water contribution areas for high aquifer vulnerability zones be included in DWSMA delineations. Therefore, we have assumed that mapping of a surface water contribution area will be required. The MDH requires that Part 1 of a WHPP include a listing of property parcels within the DWSMA (even if parcel boundaries are not used to delineate the DWSMA). We have assumed that the City will provide or be able to obtain a GIS shapefile of property parcels that can be used to prepare the parcel listing for the DWSMA. y The following criteria will be used in the WHPA delineation: o Time of travel: A 10 -year groundwater time of travel will be used to delineate the WHPAs for the Lakeville wells. In addition, the one-year groundwater time -of- travel zone and the inner Wellhead Management Zone around each Lakeville well will also be delineated, as required by the Wellhead Protection Rules. Mr. Keith Nelson, PE February 11, 2011 Page 5 o Flow boundaries: Groundwater flow boundaries such as lakes, rivers, and high capacity wells will be included in the porous media groundwater flow model used for the WHPA delineations. As indicated above, we have assumed that no modifications will be necessary to far field boundary conditions in the groundwater flow model that will be used. o Aquifer transrnissivity: As noted above, we have assumed that MDH will not require an aquifer test as part of this project. Furthermore, we have assumed that the hydraulic conductivitiesltransmissivities in the groundwater flow model to be used for this project will not be modified o Daily volume of water pumped: The daily volume of water pumped by Lakeville's wells used in the groundwater flow model will be determined by comparisons of annual water -use totals from the previous five years with projections of annual water use over the next five years. We have assumed that this water use data will be supplied to Barr by the City in electronic format such as an Excel spreadsheet. o Method used to delineate WHPAs: As noted above, we have assumed that the MDH will require both porous media and fracture flow evaluations. o Well and aquifer vulnerability: An assessment of well and aquifer vulnerability will be conducted using available geologic information. We have assumed that the MDH - supplied well vulnerability assessments for the Lakeville water supply wells will not require revisions. As noted above, well logs for up to 40 wells will be used in assessing the aquifer vulnerability within the DWSMA The vulnerability assessment will also include the preparation of to two geologic cross sections. Upon completion of the delineations and vulnerability assessments, we will prepare a report to satisfy the MDH reporting requirements for Part 1 of the WHPP. Our base cost assumes that the report and associated modeling and GIS files will be delivered in electronic format on compact disks, per MDH requirements for similar projects on which we have worked. Printed paper copies of the report can be provided to you at your request for an additional cost. ➢ The Wellhead Protection Rules require that the results of Part I of the WHPP be presented to the public at a public information meeting. This can be done by City staff. Our base cost estimate assumes that the City will make this presentation. At your request, John Greer of Barr can attend and present the results of this work at the public information meeting for an additional cost. ▪ Schedule: We have assumed that the amendment of Part 1 of the WHPP will be completed within 120 days (not .including .M.D review period) of notice to proceed. Our proposed schedule and cost estimate are based on the assumptions discussed above. As shown on the attached table, our estimated cost for this work is $11,970. It is possible that at Scoping Meeting No. 1 or the Pre- Delineation Meeting MDH may specify requirements such as additional geologic detail in the groundwater model, changes to hydraulic conductivity distribution in the groundwater model, or additional model calibration. Depending upon the scope of any additional requirements, the additional project cost would likely be in the range of $500 to $4,000. Based on our extensive experience with preparing Part I WHPPs we don't believe it M.r. Keith Nelson, PE February I,1, 2011 Page 6 likely that MDH will require significant work beyond what we have approved but we cannot completely rule it out at this time. If at Scoping Meeting No. 1 or the Pre - Delineation Meeting MDH identifies additional requirements that differ from the assumptions outlined above, we will notify you and provide you with an estimated cost for completing the modifications prior to proceeding. WHPP Part 2 Generally within a few months of the public information meeting for Part I of the WHPP, the MDH will schedule Scoping Meeting No 2 to discuss the amendment of Part 2 of the WHPP. At this Scoping Meeting, MDH staff will discuss the required inventory of potential contaminant sources, the data elements that must be must be included in Part 2, and administrative elements related to the Part 2 WHPP. One of the main tasks performed during preparation of a Part 2 WHPP is the Potential Contaminant Source Inventory (PCSI). The types of potential contaminant sources within the DWSMA that must be inventoried may include wells, storage tanks, hazardous waste generators, chemical storage /handling facilities, Class V wells, septic systems, dump sites, known spill sites and depends upon the aquifer vulnerability classifications within the DWSMA. The PCSI process includes obtaining available information from public {i.e., State, County, or City) databases and verifying locations. The location verification is very important because the locations of potential contaminant sources stored in the public databases are not always correct. Local units of government within the DWSMA must be provided a copy of the draft Part 2 WHPP for review. The Wellhead Protection Rules require that local units of government be given 60 days to review the draft Part 2 and provide comments. The City must document comments received from local units of government and how the comment is addressed in the Part 2 WHPP. After the Local Unit of Government review period, the City is required to hold a public hearing on the Part 2 WHPP. This public hearing must be held before the Part 2 WHPP is submitted to MDH for final review and approval. The Part 2 WHPP must be submitted to MDH for final review no later than April 30, 2014. Typically, a Part 2 WHPP amendment can be completed (not including final MDH review) in six to nine months. The cost to develop Part 2 of the Wellhead Protection Plan will depend on many factors including, but not limited to, size of the DWSMA, aquifer vulnerability, number and type of potential contaminant sources within the DWSMA, and project- specific requirements specified by MDH at the Part 2 Scoping Meeting, For your planning purposes, a typical cost range for Barr to complete Part 2 of a Wellhead Protection .Plan is up to S15,000 to $23,000 depending upon the level of city staff involvement in Plan development. Barr Engineering has assisted a number of communities with development of their Wellhead Protection Plans. A list of completed projects and references is available upon request.
