Staff Reports - East Bay Municipal Utility District

Findings: The project would result in maximum daily emissions levels that are below
BAAQMD thresholds. Therefore, the project's impact related to construction-period
criteria pollutant emissions is Less than Significant. However, BAAQMD recommends
implementation of construction mitigation measures to reduce construction-related
emissions for all projects, regardless of the significance level of construction-period
impacts. These measures are identified as Mitigation Measure AIR-1 in the MND and
MMRP.
Construction activities can also result in fugitive dust, which contributes to particulate
matter levels. While construction-period dust emissions have been estimated, BAAQMD
does not have a threshold of significance for fugitive dust impacts, but instead regards
fugitive dust impacts to be mitigated if appropriate management practices are
implemented. BAAQMD-recommended basic construction management practices are
included in Mitigation Measure AIR-1.
Consistent with BAAQMD recommendations, the fugitive dust emissions presented in
the MMRP have been reduced by 53 percent to reflect implementation of the measures
included in Mitigation Measure AIR-1 in the MND and MMRP.
Facts in Support of Findings: Measure AIR-1 incorporating the BAAQMD "Basic
Construction Mitigation Measures" is hereby incorporated and imposed and shall be
monitored in compliance with the MMRP. Because EBMUD has agreed to this
mitigation, any air quality impacts have been avoided or will be reduced to a Less than
Significant level.
As a result of these project circumstances, and by employing this mitigation measure, the
Project will have Less than Significant impacts to Air Quality resources.
C. Biological Resources
Impact: Less Than Significant with Mitigation Incorporated
Findings: The Project site is within a developed urban area, and based on the archival
research and field surveys undertaken by EBMUD it is unlikely that special status species
occur on the Project site or that project construction and operation would interfere
substantially with the movement of any resident or migratory fish or wildlife species or
with established native resident or migratory corridors. Furthermore, potential impacts to
candidate, sensitive, or special status species associated with the Project would be Less
than Significant with implementation of the survey measures in Mitigation Measure
BIO-1 identified in the MND and MMRP and employment of avoidance and mitigation
measures to limit impacts as necessary.
Approximately five to ten trees will be removed at the 39 th Avenue Reservoir site in order
to replace the existing inlet/outlet pipeline. All other trees at the site will be preserved.
The proposed tree removals are necessary to the project and will allow EBMUD to
; maintain water service to the community and will not result in significant impacts
