Emissions mitigated using the measures listed below in Table 3.11-8 would be
further reduced. As indicated above, the 1999 BAAQMD Guidelines do not
require quantification of construction emissions, as air pollutant emissions from
construction activities are considered less than significant if all BAAQMD
required fugitive dust control measures are implemented (as appropriate,
depending on the size of the project area). Consequently, implementation of
Mitigation Measure AQ-MM-1 would reduce this impact to a less than
significant level.
Mitigation Measure AQ-MM-1: Implement BAAQMD BMPs to Reduce
Emissions of PM10
To control the generation of construction-related PM10 emissions, SLT shall
incorporate the BAAQMD BMP measures to the degree feasible to ensure
emissions are reduced as much as possible. These measures include the
following:
