Environmental Impacts of Alternatives For all the preceding reasons, the appropriate characterization of waste impacts from coal gasification is MODERATE; the impacts would be clearly noticeable but would not destabilize any important resource. * Human Health Power generation from coal introduces worker risks from coal and limestone mining, worker and public risks from coal and lime/limestone transportation, worker and public risks from disposal of coal combustion wastes, and public risks from inhalation of stack emissions. Emission impacts can be widespread and health risks difficult to quantify. The coal gasification alternative also introduces the risk of coal-pile fires and attendant inhalation risks. The staff stated in the GElS that there could be human health impacts (cancer and emphysema) from inhalation of toxins and particulates from a coal-fired plant, but did not identify the significance of these impacts (NRC 1996). Regulatory agencies, including the EPA and State agencies, set air emission standards and requirements based on human health impacts. These agencies also impose site-specific emission limits as needed to protect human health. I Overall, human health impacts from inhaling toxins and particulates generated by burning coal at a newly constructed coal gasification plant are characterized as SMALL. Socioeconomics Peak employment during construction would be approximately 1000 workers (Bily 2005). During construction of the coal gasification plant, the surrounding communities would experience demands on housing and public services that could have SMALL impacts. These impacts would be tempered by construction workers commuting to the site from other parts of Wright County or from other counties. After construction, the communities would be impacted by the loss of the construction jobs, although this loss would be possibly offset by other growth currently being projected for Wright and Sherburne counties (USCB 2004). The permanent operating staff would be between 100 to 150 workers (Bily 2005). Construction of a replacement coal gasification plant at an alternate greenfield site would relocate some socioeconomic impacts, but would not eliminate them. The communities around Monticello would still experience the impact of the loss of permanent employees, contractors, and temporary workers associated with Monticello operations. This would be partially offset by projected economic growth; the communities around the new site would have to absorb the impacts of a temporary work force and a permanent work force of approximately 100 to 150 workers (Bily 2005). Communities in Wright County in particular would experience losses in both employment and tax revenues due to the Monticello site closure, assuming the plant is constructed outside the area. This impact could be MODERATE to LARGE. In the GELS, the staff stated that socioeconomic impacts at a rural site would be larger than at an urban site, NUREG-1437, Supplement 26 8-32 August 2006 1
Environmental Impacts of Alternatives because more of the peak construction work force would need to move to the area to work. Alternate greenfield sites would need to be analyzed on a case-by-case basis. Socioeconomic impacts at a rural site could be LARGE. Overall, socioeconomic impacts of a new coal gasification plant would be SMALL to LARGE depending on the site. * Socioeconomics (Transportation) Transportation-related impacts associated with commuting construction workers at an alternate greenfield site are site-dependent, but could be SMALL to MODERATE. Transportation impacts related to commuting of plant operating personnel would also be site-dependent, but can be characterized as SMALL to MODERATE. Coal and limestone would likely be delivered to an alternate site by rail or barge. Socioeconomic impacts associated with rail transportation would likely be SMALL to MODERATE. For example, there would be delays to highway traffic as trains pass and there could be negative impacts on the value of property close to the train tracks. The socioeconomic impacts of barge delivery of coal and limestone would likely be SMALL. * Aesthetics Potential aesthetic impacts of construction and operation of a coal gasification plant include visual impairment resulting from the presence of an industrial facility, particularly exhaust stacks and flaring stacks to burn waste gas. Flaring operations would generally be visible within a 3-mi radius, particularly at night. Vapor fog from the cooling towers and stack emissions could be visible up to 10 mi or more. However, the topography throughout most of southern Minnesota is rolling, with forested tracts common in some areas. Both of these factors act to reduce the viewshed and limit potential for impairment of visual aesthetics from onsite and offsite infrastructure. If needed, new electric power transmission lines and/or a rail spur could have significant aesthetic impacts. Overall, the aesthetic impacts at an alternate site would be SMALL to LARGE depending on the location chosen. A coal gasification plant would introduce mechanical sources of noise that would be audible offsite. Sources contributing to total noise produced by plant operation are classified as continuous or intermittent. Continuous sources include the mechanical equipment associated with normal plant operations. Intermittent sources include the equipment related to coal handling, solid-waste disposal, transportation related to coal and lime delivery, use of outside loudspeakers, and the commuting of plant employees. Noise impacts associated with rail delivery of coal and lime to a plant would be most significant for residents living in the vicinity of the facility and along the rail route.
