(b) Although the modelling predictions in the table have been rounded for presentation purposes, the changes were calculated directly from model outputs. Therefore, it is possible to show small changes without an apparent change in the listed concentrations. April 2010 Shell Canada Limited 6-13 CR029
AIR ERCB SIRS 40 – 45 References Question No. 42 Section 6.1 AENV (Alberta Environment). 2003. Air Quality Model Guideline. Prepared by the Science and Standards Branch, Environmental Services Division Alberta Environment. Edmonton, AB. March 2003. AENV. 2009. Alberta Ambient Air Quality Objectives and Guidelines. Air Policy Branch. June 2009. CCME (Canadian Council Ministry Environment). 2000. Canada-Wide Standards for Particulate Matter (PM) and Ozone. Accepted November 29, 1999 for endorsement in May 2000. Request Volume 3, Section 3.4.3.2, Page 3-71, Table 3.4-13. Shell states, “The modeling results indicate that no occurrences above the 1-hr AAAQO [for benzene] were predicted for either the Base Case or Application Case for any of the regional communities.” 42a Clarify if Shell is predicting any benzene concentrations above the AAAQO anywhere in the local study area (LSA) or regional study area (RSA), excluding the regional communities and developed areas. Response 42a The following analysis of local and regional benzene concentrations has been completed to clarify Shell’s benzene predictions. Ground-level 1-hour benzene concentrations were predicted in both the local study area (LSA) and the regional study area (RSA) for the Base Case and Application Case. A summary of the results for both cases is presented in Table ERCB 42-1. The Base Case maximum 1-hour benzene concentration (excluding developed areas) is below the Alberta Ambient Air Quality Objective (AAAQO) in the LSA but above the AAAQO in the RSA. The Application Case maximum 1-hour benzene concentration (excluding developed areas) in the LSA is above the AAAQO with 13 hours per year predicted to exceed the AAAQO. In the RSA, both the Base Case and Application Case maximum 1-hour benzene concentrations excluding developed areas are above the AAAQO. There are 169 hours per year predicted to exceed the AAAQO in both cases. 6-14 Shell Canada Limited April 2010 CR029
