memo 5 of 6 4. Develop Direct Discharge Elimination Program One of the issues identified by several stakeholders during the development of the GLWMO's third generation Watershed Management Plan is that there are discharges of untreated stormwater runoff from private and public properties that are impacting the WMO's water resources. The current draft of the Watershed Management Plan contains an implementation item that states "In partnership with the cities of Roseville and Shoreview, survey public and private direct discharges to all GLWMO waterbodies and evaluate options for disconnecting, re-routing, and/or pretreating stormwater prior to its discharge to the resource." This program would search out and inspect direct discharges to the GLWMO's water resources. This would be accomplished by surveying streams, rivers and shoreline in the watershed and look for direct discharges. Suspicious discharges would be sampled and investigated. The GLWMO would work with the member communities and private landowners of the discharge to correct the problem. • Conduct direct discharge survey on all of the GLWMO's waterbodies (Owasso, Wabasso, Bennett, Snail, Grass, Judy, Emily, Bennett and Shoreview) to identify city - owned discharges, privately -owned discharges and other discharges (similar to the 2007 discharge survey conducted for Lake Owasso as part of the Use Attainability Analysis). • Review which of the discharges from the 2007 survey have been addressed. Identify successes and failures and discuss the needs of a Direct Discharge Program (or Illicit Discharge Elimination Program) with the member communities. • Develop program that would include: inventorying direct discharges, mapping direct discharges, educating the public, city staff and county staff, and tracking the removal or treatment of direct discharges to the GLWMO's water resources. This program could also include technical assistance to private landowners on Best Management Practices (BMPs) for disconnection or a cost share program to assist in the implementation of BMPs. • Cities to meet with individual landowners to discuss disconnection options. Preliminary cost estimate = $16,000 including the cities time (which would equate to 1/a of the match). 5. Seating Abandoned and Unused Water Wells to Protect Groundwater Seek $40,000 in well sealing cost -share dollars to encourage local landowners /water well owners to seal their abandoned and unused water wells. Funding could be utilized watershed -wide or targeted to specific geographic areas /conditions. For example, known areas of groundwater contamination, areas sensitive to contamination, or Wellhead Protection/Drinking Water Supply Areas. A water well sealing cost -share program can also serve as a "gateway" to increase the groundwater resource "IQ" of the general public. That is to say, public awareness of groundwater and its vulnerability to contamination. The average residential water well within GLWMO is 2 to 3 inches in diameter and is between 75 and 150 feet deep. Depending on where the well is located within the property /structure, sealing costs can range from $500 to $1,500, with an average of $1,000. Based on a 1995 well survey conducted by the Ramsey Conservation District, anywhere from 2,000 to 3,000 water wells exist in the GLWMO area. Much of the area was developed prior to city water being supplied and thus properties had wells for potable water.
