• conclusion, WFC relies on the every growing seismic data bank and blast designs to design <br />future blast, rather than use a generic scale distance factor. <br />Blasting operations at New Horizon will occasionally be conducted within 1000 feet of buildings <br />used as dwellings, public building, school, church or community building and within 500 feet of <br />facilities such as gasoline or water and sewage lines and abandoned underground mines. As <br />per Rule 4.08.1(4)(a), see Attachment 2.05.3(8)(a)-5 for blaster-certified shot patterns used <br />within the minimum distances listed in this paragraph <br />At least 30 days before initiation of blasting, WFC will provide written notification to all residents <br />or owners of dwellings or other structures located within one-half mile of the permit area which <br />explains how to request apre-blasting survey. Upon request to the Division by a resident or <br />owner of a dwelling or structure that is located within one-half mile of any part of the permit area <br />for surface mining activities, WFC will promptly conduct apre-blasting survey of the dwelling or <br />structure and promptly submit a report of the survey to the Division and to the person requesting <br />the survey. If a structure is renovated or added to, subsequent to apre-blasting survey, then <br />upon request to the Division a survey of such additions and renovations shall be performed in <br />accordance with 4.08.2. The survey will determine the condition of the dwelling or structure and <br />document any pre-blasting damage and other physical factors that could reasonably be affected <br />by the blasting. Assessments of structures such as pipes, cables, transmission lines, and wells <br />and other water systems shall be limited to surface conditions and readily available data. <br />Special attention shall be given to the pre-blasting conditions of well and other water systems <br />used for human, animal, or agricultural purposes and to the quantity and quality of the water. <br />There maybe some dwellings or structures within the mine permit boundary that will be <br />destroyed by mining activities. For these dwellings or structures, apre-blasting survey may not <br />be conducted and written permission to destroy or move these dwellings or structures will be <br />obtained by WFC. The written agreement to destroy/move structures or dwellings maybe found <br />on file or most likely in the surface/mineral agreement made between the land owner and WFC. <br />Due to the proximity of dwellings and facilities to the blasting operations at New Horizon Mine, <br />portable seismic recording instruments will be utilized to monitor blasts when 1) requested by a <br />resident or owner of a residence or structure, or 2) at the discretion of WFC to determine the <br />potential for blast damage or regulatory non-compliance.
