conclusion, WFC relies on the every growing seismic data bank and blast designs to design future blast, rather than use a generic scale distance factor. Blasting operations at New Horizon will occasionally be conducted within 1000 feet of buildings used as dwellings, public building, school, church or community building and within 500 feet of facilities such as gasoline or water and sewage lines and abandon underground mines. A map signed by a certified blaster showing these dwelling and structures can be examined in Attachment 2.05.3(6)(a)-5. At least 30 days before initiation of blasting, WFC will provide written notification to all residents or owners of dwellings or other structures located within one-half mile of the permit area which explains how to request apre-blasting survey. Upon request to the Division by a resident or owner of a dwelling or structure that is located within one-half mile of any part of the permit area for surface mining activities, WFC will promptly conduct apre-blasting survey of the dwelling or structure and promptly submit a report of the survey to the Division and to the person requesting the survey. If a structure is renovated or added to, subsequent to apre-blasting survey, then • upon request to the Division a survey of such additions and renovations shall be performed in accordance with 4.08.2. The survey will determine the condition of the dwelling or structure and document any pre-blasting damage and other physical factors that could reasonably be affected by the blasting. Assessments of structures such as pipes, cables, transmission lines, and wells and other water systems shall be limited to surface conditions and readily available data. Special attention shall be given to the pre-blasting conditions of well and other water systems used for human, animal, or agricultural purposes and to the quantity and quality of the water. There maybe some dwellings or structures within the mine permit boundary that will be destroyed by mining activities. For these dwellings or structures, apre-blasting survey may not be conducted and written permission to destroy or move these dwellings or structures will be obtained by WFC. The written agreement to destroy/move structures or dwellings maybe found on file or most likely in the surface/mineral agreement made between the land owner and WFC. Due to the proximity of dwellings and facilities to the blasting operations at New Horizon Mine, portable seismic recording instruments will be utilized to monitor all blasts. The current seismographs used at New Horizon Mine are the Thomas V100s and the Instantel DS077. The (Revised 12-07-99) 2.05.3(6~(a) 3
