Silica and Other Waste Products Silica, an abundant element that is the primary component of sand, is a byproduct of geothermal power production from certain brine reservoirs. Silica is typically de- watered, and the silica sludge is disposed of off site.104 Silica is only considered a potential hazard when found in high concentrations in the workplace, but it poses no environmental risk. Silica is found in the effluents, or treated wastewaters, that are the byproducts of drilling operations in some resources.105 Concentrations of silica are low enough in geothermal facilities that workers are not at risk. Silica is unregulated by the federal government. Other geothermal effluents are generally considered to be harmless, and even, at times, beneficial to the environment (see ìInjection of Geothermal Fluidsî). The primary "waste" in geothermal operations is drilling cuttings, comprised primarily of bentonite, a naturally occurring clay. Wastes from drilling activities, mud and cuttings, are stored in what are known as ìsumpsî for disposal according to state and federal regulations. Sumps provide secure storage for drilling mud and cuttings. They are typically lined with impervious materials to prevent leaching. XI. Noise Pollution106 There are various federal and local noise pollution regulations for geothermal power plants with which geothermal developers must comply. On the federal level, regulations of the BLM, an agency under the Department of Interior (DOI), mandate that noise at 1⁄2 mile, or at the lease boundary, if closer, from major geothermal operations shall not exceed 65 units of decibels A-weighted, or dBA. Sound is measured in units of decibels (dB), but for environmental purposes is usually measured in decibels A-weighted (dBA). A-weighting refers to an electronic technique which simulates the relative response of the human auditory system to the various frequencies comprising all sounds. Table 4 shows common sound levels along with geothermal sound levels.107 104 Brophy, Paul (1997). Environmental Advantages to the Utilization of Geothermal Energy. Renewable Energy.
