Blasting (Sections 3.5.7 and 4.5.7) - Blasting operations at the quarry will continue with the <br /> expansion. From past blasting performance at the existing site, minimal effects (no increase over <br /> current levels) from blasting are anticipated with the expansion. <br /> Energy (Section 4.6) - Vehicle fuel consumption and overall energy use should remain at current <br /> levels since the relocated roadway does not result in significantly longer trip lengths. <br /> Construction of the relocated roadway will cause a short-term increase in energy consumption. <br /> Since daily activities at the quarry are not expected to increase with the expansion, vehicle fuel <br /> consumption and overall energy use are expected to remain at current levels. <br /> Visual Effects (Section 4.7) - Visual impacts due to quarry and asphalt plant activities are <br /> expected to be minimal as buffer zones will be maintained around these activies. <br /> Since the roadway relocation will occur in the same vicinity as the existing roadway, visual effects <br /> are expected to remain similar or improve from current conditions. The highway itself will be <br /> designed to create a pleasing park-like roadway for the driver. <br /> S.4 Mitigation Measures <br /> Water Quality (Section 4.5.1) - Mitigation measures to reduce effects on water quality include: <br /> Minimizing soil exposure by the staging of grading and revegetation. <br /> Interception and/or diversion of runoff. <br /> Application of surface covers. <br /> Installation of silt fences, erosion screens, and bale barriers. <br /> Provision of grass shoulders, grass-lined ditches and vegetation buffers. <br /> Maintain a 50 foot buffer between mining operations and Phil's Creek as required <br /> by the existing special use permit. <br /> Phil's Creek will not be rerouted or disturbed by the proposed action. Temporary water quality <br /> impacts may result from construction of the roadway. To reduce negative impacts, the roadway <br /> contractor shall exercise every reasonable precaution throughout the construction period to <br /> prevent pollution of any body of water. The contractor shall also be responsible for the <br /> prevention of soil erosion and stream siltation due to roadway construction. <br /> Contractors will not ford streams with mechanical equipment unless construction is required in <br /> S-6 <br />
