~' <br /> <br />or trespassing ~s permitted. Therefore, any person in the canyon woo is there <br />without the expressed permission of Cave of the Winds or Castle Concrete is <br />trespassing on private property and could be subject to appropriate penalties. <br />ROCFC IN DRAIN=~C£: It is felt by Castle Concrete that the presence of the <br />large rocks in the drainage does not cause any significant or measurable adverse <br />effects on the drainage or the hydrology of the area. In fact, it is felt the rock <br />provides an armoring of the drainage bottom to reduce erosion and provide some <br />degree of silt deposition ability. To remove the rock mould require the <br />construction of an access road ihich would cause severe, long term damage to the <br />area which would far exceed that which was caused by the rocks falling to the bottom <br />of the drainage in the first place. <br />SLDPE DA'1W'f: In the opinion of Castle Concrete, the most severe damage to <br />the land caused by this spillage is the damage to the slope between the bottom of <br />the drainage and the top of Phase 1. Many soil gouges were caused by the large <br />rocks bouncing da..n the hillside. Several trees were also damaged or killed <br />(estimated at 6 to 12). Fbwever, because most of the vegetation or. the hillside is <br />dominated by Gambel Oak, it is felt that recovery of the shrub con~~onent will be <br />quite rapid without any additional efforts to rehabilitate the shrub damage. Garrbel <br />Oalc is noted for its ability to recover from damages such as this. <br />FAx~ever, sortie potential exists to have local areas of headword erosion develop <br />in the vicinity of the soil gouges Ca slight amount is already occurring). These <br />damages need to be corrected and a grass cover developed in these gouges using a <br />rapidly gra.~ing, sod forming grass mixture. <br />CORRECTIVE ACTION: The folla.+ing corrective actions are proposed. <br />ROCKS IN DRAINAI~: No specific corrective actim is proposE~ for the rocks <br />in the bottom of the drainage. To remove the rocks would require i:he construction <br />of an access road either do.~n the drainage or down the slope above the drainage. <br />Such a road would damage the drainage or the slope to a high degree and would <br />require maJOr rehabilitation in its own right. Therefore any seeding or <br />revegetation of the rock areas will be done in conjunction with the slope <br />rehabilitation. <br />Fia,iever the large rocks and any damaged trees which are located near the <br />mining limit will be removed as this would not cause severe damage to areas which <br />have not already been affected by nearby mining. This cleanup was planned to be <br />done prior to leaving the Phase 1 area anyway and therefore could ~e considered as <br />CORRECTIVE AC7ION PLAN SM'D~J2 ROCK SP1LL5 PArs 5 <br />
