7-20 Air Dispersion Modeling Report
7-20 Twenty-six (26) structures were included in the BPIP-Prime analysis. All structures listed on Figure 3 General Arrangement “Building and Equipment List” table/text box with heights 20-feet and above are included in the analysis. In addition, the 15-foot tall ammonia tank has been included in the BPIP-Prime analysis. Please provide the rationale for excluding other structures proposed for the site with heights equal to the ammonia tank, such as the Fire Pump Building, Emergency Generator, and Hydrogen Tube Trailer.
RESPONSE 7-20
| Consistent with EPA and RIDEM modeling guidance, the AERMOD analysis only evaluated the impacts of plumes potentially entrapped within cavity regions of those structures for which there is a potential for the cavities to extend off-site. Other structures for which there are no potential for the cavities to extend off-site were not included in the analysis.
