The buffer zone <br />would be approximately equal to the above amount of land. The <br />land areas were based on either the nitrogen limit of the soil or <br />its cadmium limit. The amount of land for landflll1ng wa~ ba~ed <br />on the trench method of landfilling. <br /> <br />6. <br /> <br />QTHER CONSiDERATIONS <br /> <br />As part of the RSM study the MWCC took a cursory look at the <br />marketing of sludge, ash and grit. Many specialty products exist <br />for the marketing of sludge, such as an animal food supplement or <br />fireplace logs. These specialty markets would not use large <br />amounts of sludge, but there may be a potential market for these <br />products in the future. <br /> <br />. <br /> <br />There are several potential markets for grit and ash, such as <br />road base material, or concrete admixtures. The MWCC concluded <br />there was no market for these materials; However, a major <br />marketing effort was not pursued. The MWCC's environmental <br />impact statement consultant said a more detailed marketing study <br />was warranted before this option is dismissed. <br /> <br />It is, therefore, recommended that the MWCC continue to pursue <br />marketing O.~t"he sludge, ash and grit. The quantity of land for <br />final disposal may be reduced by carrying out this recycling <br />effort. <br /> <br />1. CONCLUS10NS <br /> <br />A. The MWCC has completed its 20' facility plan on r~sidual <br />solids management and has submitted a recommendation for <br />implemen ta tioD. <br /> <br />B. The MWCC Plan covers needed improvements during the next 20 <br />years. Therefore, the land needed for the siting of dis- <br />posal facilities should c~ver the same period. <br /> <br />. <br /> <br />The MWCC currently owns this land. However, these sites must <br />also be chosen by the Council under of this site selection <br />process or the MWCC cannot continue to use these sites for sludge' <br />disposal. If these sites are found not to be acceptable, a like <br />amount of acceptable acreage must be found. <br />
