Final Environmental Impact Statement—Zavoral Mine and Reclamation Plan
City of Scandia
• Monitor the mitigation methods used at the Site to reduce emissions of fugitive dust for the life of the
Project. Records of the sweeping and water application would be maintained to document the
fugitive dust control measures. The City should require Tiller to provide a funding mechanism to
conduct any and all City-required monitoring at the Site to confirm that sufficient dust control
measures are being implemented.
• Require Tiller to identify methods to control tracking on public roadways as part of their Dust Control
Pian.
• Require noise mitigation techniques, such as developing berms and screens for the Zavoral Site, are
implemented. Tiller should provide a funding mechanism for monitoring.
• Require the use of broadband alarms for Tiller equipment and an on-site circular traffic pattern for
haul trucks.
• Consider a condition that the mine could operate only between the hours of 7 a.m. and Noon on
Friday. This would also reduce the potential impact of the proposed Project on recreational traffic
during that time frame.
• Require inspection of trucks and on-site equipment to determine that mufflers are in good working
order.
• Monitor to ensure that the proposed screening and reclamation strategies are successfully
implemented.
• Establish a maximum stockpile height limit of approximately 880 feet mean sea level. Stockpiles
limited to this elevation would be effectively screened by proposed and existing berms. Locating
stockpiles on the west side of the Site should be minimized, as the upper slopes of stockpiles would
have a greater potential to be within the viewsheds of sensitive viewpoints.
• Limit non-daylight lighting to what is required for safety and security. All such lighting should consist
of shielded, downward directed lighting.
• Require that all trees be inspected for raptor nests prior to any tree clearing.
• Require Tiller to coordinate with the City regarding which berms would be removed after the project is
completed.

ES 4 AREAS OF CONTROVERSY
ES 4.1 EIS Timing and Comprehensive Plan
Take Action -Conserve Our Scandia (TA-COS)is a group of concerned residents that are opposed to the
development of the gravel mine on the Zavoral property. TA-COS's stated mission is "To promote
sustainable development in Scandia while endorsing conservation of its waters,wildlife, natural and
historic resources and beauty, referring to the Scandia Comprehensive Plan as its visionary guide."
In appearances before the Scandia City Council on November 16, 2010, and December 7, 2010, and in
letters dated November 23, 2010, and December 6, 2010, TA-COS raised two primary objections to
allowing Tiller to continue its application for the CUP.
First, the TA-COS representative stated that Tiller failed to meet its obligation to complete the EIS within
280 days as required by Minn. Stat. § 116D.04. 2A(h).

• Although no Blanding's turtles were identified at the Site, the MnDNR has requested that Blanding's
turtle mitigation measures be applied to the Project. These measures are included in Appendix C.
• Require Tiller to monitor all on-site construction equipment for leaks and receive regular preventive
maintenance. Fueling and maintenance of vehicles would occur within the active mining phase and
no"topping off"of vehicle fuel tanks should be allowed.
• Require that any AST at the Site be located more than 500 feet from surface water to reduce the
potential for impacts to surface water.
. Notify the MPCA about all ASTs within 30 days of installation by submitting an AST Notification Form.
• Require Tiller to sample and analyze groundwater for diesel range organics. If it is ever determined
that gasoline is to be stored on the Site, gasoline range organics and benzene should be added to the
analyte list.
• Construct the new driveway access directly across from TH 97 as required by Mn/DOT for safe
access.
• Require Tiller to record and report the number and source location of trucks hauling add-rock to the
Scandia Mine to ensure that additional truck traffic would not result from hauling from the Zavoral Site
at peak demand concurrently with other sites.
• Install MMUTCD-compliant truck warning signs on State Scenic Byway TH 95 to advise drivers of
trucks crossing TH 97 in and out of the Zavoral Site. The installation of warning flashers is another
option but should be discussed with Mn/DOT to evaluate the safety impacts.
• Monitor the mitigation methods used at the Site to reduce emissions of fugitive dust for the life of the
Project. Records of the sweeping and water application would be maintained to document the
fugitive dust control measures. The City should require Tiller to provide a funding mechanism to
conduct any and all City-required monitoring at the Site to confirm that sufficient dust control
measures are implemented.
• Require Tiller to identify methods to control tracking on public roadways as part of their Dust Control
Plan.
. Require noise mitigation techniques, such as developing berms and screens, for the Zavoral Site are
implemented. Tiller should provide a funding mechanism for monitoring.
. Require the use of broadband alarms for Tiller equipment and an on-site circular traffic pattern for
haul trucks.
• Consider a condition that the mine could operate only between the hours of 7 a.m. and Noon on
