Total proposed excavation is 14' wide x <br /> 22' long x 17' deep. The total amount ns ziditional excavated soil will Ge <br /> 9 cubic yards. All spoils will be placed on plastic and <br /> approximately 16 <br /> covered with same in the area immediately west of the excavation. Soil samples <br /> will be taker, by the above properly licensed facility from the teeth of the <br /> hoe bucket with brass tubes. Samples will be taken in the appropriate places; <br /> ach <br /> 2 from the bottom of the excavation and twill bee middle of analyzedforeaTX RhEeandll <br /> for a total of 10 samples.
