worker receptor location), which would not exceed the BAAQMD cumulative
<br /> cancer risk threshold of 100 in a million. The maximum potential cumulative
<br /> chronic health index associated with the Project is 0.40 (occurs at an existing on-
<br /> site worker receptor location), which would not exceed the BAAQMD's chronic
<br /> hazard index threshold of 10. The maximum potential cumulative annual average
<br /> PM2.5 concentration associated with the Project is 0.49 µg/m3 (occurs at an
<br /> existing off-site residential receptor location), which would not exceed the
<br /> BAAQMD's threshold of 0.8 µg/m3. Therefore, cumulative impacts due to
<br /> exposure of sensitive receptors to TACs would be less than significant. (See
<br /> Revised HRA Tables 10 and 11 in Response to Comments Appendix B.)
<br /> • All three air quality impacts identified in the Draft SEIR as significant and
<br /> unavoidable due to Project operations—operational emissions of criteria air
<br /> pollutants (Impact 4.B-2), conflict with the applicable air quality plan
<br /> (Impact 4.B-3), and cumulative emissions of criteria air pollutants (Impact
<br /> 4.B-6)–have now been found to be less than significant First, average daily
<br /> full-buildout operational emissions of ROG,NOX, PM10, and PM2.5 would be
<br /> 47.48, 34.16, 75.70, and 20.68 pounds per day, respectively. In addition, Phase 1
<br /> operational emissions plus Phase 2 construction emissions of ROG,NOX, PM10,
<br /> and PM2.5 would be 49.95, 22.55, 35.91, and 10.07 pounds per day, respectively.
<br /> These emissions do not exceed BAAQMD's threshold for ROG,NOX, and
<br /> PM2.5 of 54 pounds per day and for PM10 of 82 pounds per day. Therefore,
<br /> mitigation is not required and the impact would be less than significant. Second,
<br /> operation of the project would not conflict with or obstruct implementation of the
<br /> applicable air quality plan (the BAAQMD 2017 Clean Air Plan)because
<br /> operational emissions of all criteria pollutants are below the project-level
<br /> thresholds and the project would be consistent with the applicable air quality
<br /> control measures contained in the 2017 Clean Air Plan. Therefore, mitigation is
<br /> not required and the impact would be less than significant. Third,the cumulative
<br /> air quality impact from operations of the project would not be cumulatively
<br /> considerable because operational emissions of all criteria pollutants are below the
<br /> project-level thresholds and, according to the BAAQMD, effects related to criteria
<br /> air pollutants are inherently cumulative impacts because no single project is
<br /> sufficient in size to, by itself, result in nonattainment of ambient air quality
<br /> standards. Therefore, mitigation is not required and these impacts would be less
<br /> than significant. (See Revised HRA Tables 7, 8, 10, 12 in Response to Comments
<br /> Appendix B; Draft SEIR pages 4.B-24-25.)
<br /> • Phase 1 operational air quality impacts (not modeled separately for Phase 1 in
<br /> the Draft SEIR) are less than significant Average daily operational ROG,
<br /> NOX, PM10, and PM2.5 emissions for Phase 1 would be 53.27, 53.91, 55.32, and
<br /> 15.43 pounds per day, respectively. These emissions do not exceed BAAQMD's
<br /> threshold for ROG,NOX, and PM2.5 of 54 pounds per day and for PM10 of 82
<br /> pounds per day. Therefore, ROG emissions would not require mitigation and
