Environmental control technologies are essential elements to be included in the overall design of Imperial Valley geothermal power systems. Environmental controls applicable to abatement of hydrogen sulfide emissions, cooling tower drift, noise, liquid and solid wastes, and induced subsidence and seismicity are assessed here. For optimum abatement of H2S under a variety of plant operating conditions, removal of H2S upstream of the steam turbine is recommended. The environmental impact of cooling tower drift will be closely tied to the quality of cooling water supplies. Conventional noise abatement procedures can be applied and no special research and development are needed. Injection technology constitutes the primary and most essential environmental control and liquid waste disposal technology for Imperial Velley geothermal operations. Subsurface injection of fluids is the primary control for managing induced subsidence. Careful maintenance of injection pressure is expected to control induced seismicity. (MHR).

This report summarizes the important findings of a two-volume report that deals with the potential impacts and environmental controls associated with the operation of geothermal power plants in California's Imperial Valley. The valley contains nearly a third of the nation's total energy potential for identified hot-water resources. Possible impacts of developing those resources include violation of air quality standards if emissions of hydrogen sulfide are not abated, negative ecological effects resulting from increased in the salinity of the Salton Sea, and damage to irrigation systems caused by land subsidence induced by the extraction of geothermal fluids. Other minor impacts concern occupational health and safety, socioeconomics, and hazardous wastes. Analyses of environmental impacts and the control measures for minimizing negative impacts are based primarily on a projected production of 3000 MW of electrical power by the year 2010.
