Road, thereby keeping all traffic generally within the County's solid waste processing complexes and internal roadway network. The applicant anticipates about 4 to 5 rock-hauling trucks, or 8 to 10 tractor trailers will be making about three (3)trips per hour between the proposed quarry and applicant's baseyard and processing facilities. However, due to the damage to the roadway and safety concerns between regular vehicle traffic to solid waste facilities and other recreational facilities in the area, the Department of Environmental Management has required that the current use of rock haulers cease once quarrying operations of the permit area commences. Instead, the applicant must use highway legal vehicles to haul quarried materials from the quarry site to the applicant's processing facilities. Furthermore, DEM requires that the applicant inform them of the starting date of the quarry operations. The preceding will be added as a condition of approval. According to the State DOT, the proposed project will have no anticipated impact to State highways. While the proposed permit area is situated 1.75 miles from the Hilo International Airport, the proposed use does not underlie any approach or departure flight tracks. Furthermore, due to the nature of the proposed quarry operations as an extension of an existing and adjacent quarry, there does not appear to be any situation that would be cause for concern upon airport operations, such as creating a wildlife attractant, visual glare due to standing water or any aerial obstructions. However, DOT-Airport's Division requested that the applicant coordinate with the Hawai`i Airports District Manager to ensure compliance with existing regulations. The preceding will be added as a condition of approval. If applicable, the applicant will be required to secure an Air Pollution Control Permit, a National Pollutant Discharge Elimination System (NPDES)permit and an Underground Injection Control (UIC)permit from the State Department of Health before the commencement of quarry activities. Electrical and telephone are not required for the quarry operation. Water for dust suppression will either be trucked to the site or provided by catchment tank. Portable -5-
