Acoustical Evaluation of Station Upgrades PSE&G West Orange Switching Station, West Orange, NJ 5 June 2024 Page 11 Future Conditions Proposed plans call for the installation of new equipment and systems. Detailed information on the new equipment was entered into the model. This information was discussed in a previous section. Figure 4 provides the results of modeling the steady future sound emissions from the site with the new equipment operating with all HVAC equipment ON. Comparison of these results with the existing conditions in Figure 3 shows that future emissions remain the same at all nearby noise- sensitive receptors. At residential Receptors A, C, and D, emissions meet the code limit of 50 dB(A) by 4 dB. In the direction of commercial uses, maximum emissions meet the 65 dB(A) code limit by 17 dB or more. Note that, once again, the gray 50 dB(A) contour, does not extend past the property line in the direction of noise-sensitive receptors. These results indicate that the future site layout will continue to comply with code limits, even after a conservative analysis with all HVAC equipment and transformer cooling fans operating. There is also full compliance in all octave frequency bands. While not presented in this report, site sound emissions during the cooler months with no HVAC equipment operating are expected to be lower in level at all nearby points of reception than what is shown in Figure 4.
