• (6) Will not result in the destruction, loss or damage of a natural, scenic or historic feature of major importance. (7) Will fully comply with all other requirements of this Code, including any applicab/e requirements and standards for the issuance of a license or permit to establish and operate the proposed use in the city. 4.3 WRITTEN STATEMENT ADDRESSING REQUIRED FINDINGS Written statements regarding each of the required findings are provided below. (1) Will not endanger, injure or detrimentally affect the use and enjoyment of other property in the immediate vicinity or the public health, safety, morals, comfort, convenience or general welfare of the neighborhood or the city. An Environmental Impact Statement (EIS) was prepared and approved in 2006 for this project (see Exhibit 2). The EIS evaluated potential impacts to groundwater, adjacent wetlands, and air quality and determined that impacts from the proposed expansion were expected to be minimal, or that adequate mitigation plans were in place to address potential impacts. Consistent with its approved CUP for the existing MSW landfill, the following standards will continue to be met for the proposed SDA: • Groundwater. The SDA, as designed, is a modern, lined landfill that meets or exceeds all health and safety regulatory requirements. Modern landfills are designed to protect groundwater by preventing a release from contacting the environment outside of the landfill and by minimizing the volume of liquid (leachate) that could impair groundwater quality in • the event of a release. Groundwater monitoring networks and monitoring programs are additional design features that detect changes in water quality that can indicate a failure of the liner system before it becomes a health risk and to allow for implementation of corrective actions to prevent an impact to the environment. Federal, state, and county regulations establish siting, monitoring, water quality, and other standards to protect groundwater resources. The site development and analysis and monitoring well network proposed for the SDA meet or exceed those standards and requirements.

ERL will maintain backup pumps for use in the event of pump failure at the leachate sump, wet well and leachate storage tank on-site. As an alternative, ERL will maintain provisions for restoring temporary leachate pumping within a 24-hour period and adhere to the current "Leachate Management • Plan" as approved by MPCA.
