App' y <br /> site will be aerated according to the guidelines specified b22the <br /> 1San <br /> ay <br /> Joaquin County Air Pollution Control District. <br /> 6ninclhes to 1 foot <br /> approximately 60 cubic yards of soil were sQ <br /> thick. The soil was turned a minimum of two times a day. <br /> The PID survey was conducted by a Kleinfelder environmental geologist on <br /> May 28, 1987. Soil samples were screened at 12 sample points in the <br /> spread soil. No readings <br /> had asP12ereadingfrom lofo126the <br /> partssoil <br /> per million <br /> screened.
