Such a survey will <br />determine only the surface condition of pipes, cables, transmission lines, wells and other <br />water systems; however, special attention will be given to the pre-blasting conditions of wells <br />and other water systems used for human, animal or agricultural purposes and to the quantity <br />and quality of that water. <br />A written report of any pre-blasting survey will be prepared and signed by the person <br />conducting the survey. This report will include any proposed adjustments to the blasting <br />program which might be necessary to be incorporated or should be incorporated to prevent <br />damage. A copy of the report will be provided to the person requesting the survey and to the <br />Division.
