1-12 Noise
Please detail all steps Invenergy plans to take, such as for example, with the bypass valve, hogging air injector and drain vent, to maintain the sound level below 43 dBA during normal startups.
RESPONSE:
| The bypass valves will be located indoors and will utilize low noise design features, including low-noise valves and steam discharge stack resisters, so as to comply with the proposed limits. The vents from the hogging air ejector vent will include a silencer. Invenergy has taken reasonable steps to control noise levels during start up and shut down, and Invenergy anticipates that it can achieve 46 dBA.
