4.3 Water Resources
Other Construction Issues
Earthmoving equipment and cranes will be used on the beaches to spread the material pumped to the beach
and to place and maintain the discharge pipeline. Vehicle use has some potential for introducing
contaminants to beach fill sediments from minor spills and leaks fromthe equipment. No significant impacts
are anticipated since no refueling or fuel storage will occur on the beach, and the dredging contractor will
be required to develop a Spill Prevention Control and Counter-Measure Plan (SPCC) prior to initiating
pumping operations. Additional protection will be provided by the contractor using biodegradable (e.g.,
vegetable oil-based) lubricants and hydraulic fluids, and/or electric or natural gas powered equipment,
where practicable.
Mitigation Measures for Alternative 1a
There would be no significant impacts so no mitigation measures would be required. Some monitoring
would be required consistent with the RWQCB permit.
Impacts/Mitigation Measures for Alternative 1b
As shown in Table 2-2, there would be longer construction periods for several receiver and borrow sites
when compared to Alternative 1a. Although the construction period would be longer at these receiver and
borrow sites, the same construction practices (e.g., training dikes) and monitoring would be performed.
Construction would also still be short-term, and no significant impacts to water quality would result with
implementation of this alternative. Some monitoring would be required consistent with the RWQCB permit.

Impacts of Alternative 2a
Receiver Sites
Construction at receiver sites in South Oceanside, South Carlsbad, Torrey Pines, Mission Beach, and
ImperialBeach would take incrementally longer under this alternative thanAlternative 1 because theywould
receive more sand. Still, the impacts would remain localized and training dikes would help reduce turbidity.
No significant impacts to water quality would occur at these receiver sites. Several receiver sites that are
