Major Noise Sources and Mitigation Cost Estimates for Gas-Fired Power Facilities

 

Abstract

In designing gas-fired power plants, the power generation industry often ignores noise propagation, believing any potential problems will go away, provided the plant meets the Occupational Safety and Health Administration–specified maximum noise level of 85 dBA within operating areas. Operators believe that, should noise complaints arise from nearby residents, they can be dealt with by retrofitting some simple mitigation such as a noise barrier. This approach is aimed at lowering upfront cost. However, due to the difficulty of retrofitting mitigation on major noise-generating equipment, this is a high-risk approach, potentially leading to millions of dollars of post-construction expenses, lost revenue, costly litigation, and liability damages.
