wells to excavate and vent gas from the landfill itself. Solid waste <br />processing facilities can minimize the potential for gas accumulation <br />through proper design and monitoring. <br />Aesthetic and other miscellaneous environmental impacts associated <br />with solid waste facilities are litter, noise and odors. Litter can <br />be controlled by using fences, properly positioning solid waste as it <br />is dumped, and properly designing and maintaining processing facili- <br />ties. Noise for solid waste facilities may be reduced by mufflers or <br />barriers. Where building walls are of lightweight construction, <br />heavier or secondary walls are suggested to reduce noise. Odors can <br />be minimized by periodically covering the waste with soil, and by pre- <br />venting anaerobic conditions from developing in transfer and holding <br />facilities. <br /> Hazardous waste management involves a number of activities with the <br /> potential for releasing pollutants to the environment. Hazardous air <br /> emissions can result from industrial and commercial processes, trans- <br /> porting hazardous waste, and treating and/or disposing of hazardous <br /> waste. Groundwater may be contaminated by leachate moving from <br /> hazardous waste spills (including deliberate dumping), storage, <br /> treatment, or disposal areas. Surface water may be contaminated from <br /> hazardous waste spills, runoff from hazardous waste storage, treat- <br /> ment, or dis-posal areas (including overflows from impoundment), <br /> discharges from hazardous waste generating or treating facilities, <br /> and discharge of groundwater contaminated by pollutants moving below <br /> the surface. The environmental effect of hazardous waste can be <br /> minimized by combining on-site (point of generation) treatment of <br /> some wastes, off-site (central facility) treatment, and by land <br /> disposal or storage of wastes that remain hazardous after treatment. <br /> <br />Objectives <br /> <br />5. Ensure that proposed solid and hazardous waste facilities protect <br /> the public health and welfare and minimize environmental <br /> degradation caused by facility construction and operation. <br /> <br />Criteria <br /> <br />5a. The site selection process for land disposal facilities should <br /> include an evaluation of the site's capacity to assimilate waste <br /> and its constituents. <br /> <br />5b. Solid waste applicants should ensure that environmental monitor- <br /> ing will be conducted when the facility is operating, and would <br /> include evaluations of air and water quality. Continuously <br /> recording instruments should be used to the extent practicable. <br /> The facility should provide the responsible.agency with records <br /> and monitoring data. If no adverse effect 1s expected from a <br /> facility because of low volume or inert or innocuous wastes, or <br /> because the control technology and practice are reasonably able <br /> to meet environmental standards, the Council, along with other <br /> responsible agencies, may determine that environmental monitoring <br /> is unnecessary. <br /> <br /> <br />
