How much noise is the plant going to create?
The majority of noise-emitting equipment will be housed within a building to reduce noise emissions.Exterior sources of noise will include the radiators, switchyard transformers, natural gas metering and pressure reduction station, and exhaust stacks.Each will be designed and procured with low-noise specifications. In addition, the landscaped berm planned for the Clawiter Road frontage will provide noise reduction. Computer modeling of the plant (without consideration for the effects of either the landscaping berm or intervening buildings) demonstrates that expected noise levels at the nearest homes will not increase more than 5 dBA above current background levels. The CEC Staff consider a noise increase less than 5 dBA to be insignificant because most individuals will not perceive a noise increase at this level to cause a noticeable difference from background noise levels.The modeling has also demonstrated that noise will conform to ambient noise guidelines established by the City.
