channel and severing approximately 20 acres from the property. Should this occur, major damage to the downstream opposite bank would occur as well as damage to downstream water supply facilities. This would further exacerbate siltation in the down stream section of the river between river miles 66 - 64 and below. This situation is easily corrected by the proposed project. The proposed project has many benefits to the long term environmental protection of this important section of the San Joaquin River. The majority of these benefits have been described in regard to the prevention of serious damage that would result from the development of an avulsive cut across the property. In addition to the reclamation aspects, the project owner is proposing to set aside a section of land located approximately at river mile 62 wetland development and vegetation and wildlife preservation. This site was previously severed from the west bank of the San Joaquin by a major avulsive cut during flooding in 1986. The wildlife habitat potential of this area is deemed to be far superior to that which may be impacted by the project. The proposed mitigation area is outlined here as Attachment II. PROPOSED/EXISTING SURFACE MINING OPERATION 13. Proposed starting date of operation Upon issuance of permit? Summer, 1989 Estimated life of operation? The initial operation is expected to have a five year operating life, however, long term maintenance is proposed for the site. This maintenance will involve the continual removal of flood derived accumulations of sand on an annual basis. Duration of first phase? Five years. 14. Operation will be continuous seasonal X intermittent developed, not yet in operation temporarily deactivated stockpile in mine 15. Operation will be under 5,000 tons (cubic yards)/year 5,000-50,000 tons (cubic yards)/year 50,000-250,000 tons (cubic yards)/year X , 100,000 yd3/yr. 250,000-1,000,000 tons (cubic yards)/year over 1,000,000 tons (cubic yards)/year
