Title: Quantifying the efficiency and equity implications of power plant air pollution control strategies in the United States

Abstract

We modeled the public health benefits and the change in the spatial inequality of health risk for a number of hypothetical control scenarios for power plants in the United States to determine optimal control strategies. We simulated various ways by which emission reductions of sulfur dioxide (SO{sub 2}), nitrogen oxides, and fine particulate matter (PM2.5) could be distributed to reach national emissions caps. We applied a source-receptor matrix to determine the PM2.5 concentration changes associated with each control scenario and estimated the mortality reductions. We estimated changes in the spatial inequality of health risk using the Atkinson index and other indicators, following previously derived axioms for measuring health risk inequality. In our baseline model, benefits ranged from 17,000-21,000 fewer premature deaths per year across control scenarios. Scenarios with greater health benefits also tended to have greater reductions in the spatial inequality of health risk, as many sources with high health benefits per unit emissions of SO{sub 2} were in areas with high background PM2.5 concentrations. Sensitivity analyses indicated that conclusions were generally robust to the choice of indicator and other model specifications. Our analysis demonstrates an approach for formally quantifying both the magnitude and spatial distribution of health benefits ofmore » pollution control strategies, allowing for joint consideration of efficiency and equity.« less

  • Pollutants that have been found to elicit plant response may be classified as (1) acid gases, (2) herbicides and pesticides, (3) primary products of combustion, (4) products of reactions occurring in the atmosphere, and (5) miscellaneous effluents. The discussion in this paper is confined to the first, third, and fourth of these classifications.
  • The report is entitled Toxic Air Pollutants: State and Local Regulatory Strategies - 1989. The 364-page report is the result of a survey of state and local air pollution control agencies, which solicited information on their programs to control air toxics. According to the survey, every state currently has a program to address emissions of air toxics. Additionally, 27 of the 40 local agencies that responded to the survey have, or are developing, air toxics programs. The strategies employed by state and local agencies vary widely, including control technology requirements, risk assessment, acceptable ambient guidelines, or a combination of thesemore » approaches. This is a report summarizing the air toxics control programs currently implemented (or under development) by state and local air pollution control agencies throughout the US. The report is based upon a survey of all 50 states and 220 local air pollution control agencies conducted by the State and Territorial Air Pollution Program Administrators (STAPPA) and the Association of Local Air Pollution Control Officials (ALAPCO). This survey updates one published five years earlier.« less
  • After four months of successful operation, the Carneys Point generating facility has demonstrated the viability of selective catalytic reduction technology in coal-fired applications. This is the first coal-fired plant in North America to successfully use SCR. The plant achieves 95% SO[sub 2] removal, particulate emissions below 0.02 MM/Btu, and is able to comply with state NO[sub x] emission standards. Financing of the project is also described.
  • Lotic fish have developed life history strategies adapted to the natural variation in stream flow regimes. The natural timing, duration, and magnitude of flow events has contributed to the diversity, production, and composition of fish assemblages over time. Studies evaluating the role of hydrology in structuring fish assemblages have been more common at the local or regional scale with very few studies conducted at the continental scale. Furthermore, quantitative linkages between natural hydrologic patterns and fish assemblages are rarely used to make predictions of ecological consequences of hydrologic alterations. We ask two questions: (1) what is the relative role ofmore » hydrology in structuring fish assemblages at large scales? and (2) can relationships between fish assemblages and natural hydrology be utilized to predict fish assemblage responses to hydrologic disturbance? We developed models to relate fish life histories and reproductive strategies to landscape and hydrologic variables separately and then combined. Models were then used to predict the ecological consequences of altered hydrology due to dam regulation. Although hydrology plays a considerable role in structuring fish assemblages, the performance of models using only hydrologic variables was lower than that of models constructed using landscape variables. Isolating the relative importance of hydrology in structuring fish assemblages at the continental scale is difficult since hydrology is interrelated to many landscape factors. By applying models to dam-regulated hydrologic data, we observed some consistent predicted responses in fish life history strategies and modes of reproduction. In agreement with existing literature, equilibrium strategists are predicted to increase following dam regulation, whereas opportunistic and periodic species are predicted to decrease. In addition, dam regulation favors the selection of reproductive strategies with extended spawning seasons and preference for stable conditions.« less
  • The Clean Air Act mandates the Environmental Protection Agency to required owners or operators of emissions sources where regulated substances are present to prepare and maintain a risk management plane and an emergency response plan. Each risk management plan must include an assessment of the potential effects of releasing any regulated substance. Each hazard assessment, in turn, must contain an estimate of potential released quantities and a determination of downwind effects. Risk management plans must be submitted to the Chemical Safety and Hazard Investigation Board, the state and the local emergency planning committee. CAAA requires the Department of Energy tomore » make the Liquefied Gaseous Fuels Spill Test Facility (Nevada Spill Test Facility) near Mercury, Nev., available to industry, federal agencies and other interested parties to conduct spill and mitigation research. The law also requires EPA and DOE to cooperate in overseeing experimental and analytical research at the facility.« less
