Examples of mitigative measures include installing a <br />liner and leachate collection system to prevent groundwater contamination at a <br />landfill, or providing a litter fence to catch blowing wastes. Although miti- <br />gative measures can be taken to reduce many impacts, some impacts cannot be or <br />are too costly to be mitigated. In those cases compensation may be <br />appropriate. <br /> <br />Although current solid waste disposal practices may involve some risk, selec- <br />tion of sites for sanitary landfills is much more rigorous now than in the <br />past. There are cases where it was discovered that hazardous wastes were <br />disposed of in sanitary landfills. New hazardous waste regulations prohibit <br />disposal of hazardous substances in sanitary landfills; however, small amounts <br />of hazardous wastes still could be buried in landfills because homeowners may <br />discard such wastes as paint cans, insecticides and herbicides into the solid <br />waste stream. Thus, it is desirable that new landfill sites provide protection <br />against the release of such contaminants. <br /> <br />In Minnesota, when waste disposal facilities are sited, every effort is made to <br />select environmentally suitable sites that are also compatible with surround- <br />ing land uses. This is a striking contrast to the random disposal of wastes in <br />dumps, which was common practice across the country in the past. Furthermore, <br />the new landfills assuredly will incorporate the latest design and engineering <br />techniques, in contrast to 'the marked lack of adequate design and engineering <br />found at the old dumps. <br /> <br />Nevertheless, no matter how much the siting process, landfill design and <br />engineering technology have improved, adverse impacts from solid waste disposal <br />facilities may still occur. Consequently, it is important to mitigate any <br />adverse impact resulting from construction and operation of waste disposal <br />facilities. Mitigating adverse impacts not only makes a facility 'safer, but~ <br />also makes it more acceptable to the host community. <br /> <br /> <br />
