The Special Town Board meeting of the Town of Cooks Valley was called to order on Tuesday, April 10, 2018 at the Cooks Valley town hall located at 15751 40th Street at 7:30 pm by Chairman Darrel Fehr.  Supervisors present were David Clements and Matt Borofka.  Other town official present was Deputy Town Clerk Mary Jo Fehr.

Review of EOG non-metallic mining permit with public comment:
Dave Bokor, representative for EOG, gave an overview of the year and production of the EOG DS mine.  The mine was operational May 1 to November 1, 2017 with 560,000 tons of raw frack sand hauled out and 197,758 ton of waste sand hauled back. 
They resumed hauling raw sand on April 5, 2018 and are projected to operate through the end of October, 2018.  They anticipate pulling out more tonnage, approximately 115,000 ton per month and will operate Monday through Friday, 6:00 am – 4:30 or 5:00 pm, with the possibility of running one  weekend per month if needed to make-up lost production due to weather or unexpected equipment failure.  Planned activity will be concentrated on the north and east areas of the mine. Most of the new ground is exposed so not a lot of overburden.  Waste sand will be used to back-fill against the high wall on the west side.  Reclamation activity will be the same as last year.  They will continue to operate water trucks when required to manage dust control and monitor vegetation development/growth, continued maintenance of all BMPs inspected monthly.  Rip-rap, ditches, maintenance of erosion control measures to standard inspected monthly.
Recent concerns from neighbors (Larson's, Harmon's) regarding blasting activity last fall and March 2018.  Will add these to the notification/call prior to blasting and evaluate several future blasting activity with portable seismographs on their property.  Also investigate the potential to evaluate Harmon's new construction area of house as pre-blast inspection.  Estimated blasting frequency at DS mine for 2018 of once per week between the hours of 10:30 am and 2 pm.  Blast duration is 1-2 seconds.  There are three permanent monitors in place at the east, south, and north sites of the mine.  Z-curve analysis are recorded for every blasting activity on each of the monitors measuring peak particle velocity vs. frequency.  There is no evidence at this time that blasting is causing well damage.\
There are six existing storm water ponds.  Appropriate residences will continue to be notified and scheduled in cooperation with them when storm water is being discharged.  The mines are required to manage existing wetland area per WDNR requirements, improvements will allow to control and minimize discharge while maintaining quality of water.  They have adopted a more stringent plan than required which meets or exceeds the state regulations.  Pond B3.0 was discharged eight days; pond B8.0 20 days.  A monitoring well DSMW-4 is located just past the south edge of the B8 storm water pond and was tested routinely as required by permit. A third party is hired for sampling.  Neighboring wells will be tested every three years as requested.  Mark Berge requested that his well water be tested this year.  Mark Berge raised concern about the released water causing erosion in his pasture.
EOG  met with PurFrac in early April regarding a road agreement.  They agree in principal with respect to initial cost, current condition (% used), and shared portion of the road.  EOG is reviewing
the proposal from PurFrac.
No land is ready for final reclamation in 2018.
Will be running 26-28 trucks with one crew of drivers. 
Motion made by Darrel Fehr, seconded by Dave Clements to adjourn at 8: 35 pm. Motion carried 3-0.
