Also, it has come to my attention that if you do approve the <br /> variance to pressure grout instead of over drill VW-1 and VW-2, we need a variance for the following SJC <br /> Well Standards requirement: "a hole at least one foot larger in diameter than the originally drilled hole <br /> shall be excavated around the outside of the well casing to a depth not less than three feet below the <br /> ground surface." Please call me with any questions.
