1-3 Noise
RESPONSE
| CREC operation is expected to be typical of other base load power generation facilities and should be running at normal operating level more than 80% of the time. This means that start up and shut down will be somewhat frequent events occurring typically once a month during winter and summer conditions and once a week or even daily during the spring and fall. Noise produced from the various components will vary depending upon the plant load and its mode of operation. Noise produced from these components is from motors, pumps and ancillary equipment skids, as summarized in Table 1.3.1 which was included in the Noise Evaluation report included as Appendix E in the EFSB application and modified to show number of components operating or their percent load during normal and start up or shut down conditions.
The above table indicates the expected number of components that will operate during normal conditions and during start up and shut down. The expected noise for these two modes of operation and other transient modes of operation is included in the response to Question 1.5 below.

[1] - Quantity active during full load operation. For pumps and compressors installed in sets of 2 or 3, it is assumed that one set will be reserved for backup and remain on standby.
