Final Mitigated Negative Declaration and Response to Comments

PUBLIC SERVICES
No project requirements or mitigations measures are necessary.
RECREATION
MITIGATION MEASURES REC-1: Boating Access
Work will be coordinated with tour boat operators in Lake Tahoe to determine the least
disruptive days and hours to conduct work. Work will occur during these days and time
periods to the extent possible.
Emerald Bay will require traffic control for motorized boat traffic for up to 6 hours per day for
an estimated 4 weeks during barrier installation and 4 weeks during barrier removal, and
during some alternative treatment work. Non-motorized boats and escorted motorized
boats may be allowed to pass through the mouth if the water level is high enough to allow
passage and maintain the safety of the divers.
Public notices will be used to inform the public of temporary boat traffic control.
Work will be scheduled during the mornings and on weekdays to the extent possible. No
boat traffic control would occur during the weekend, unless there is a need to re-secure a
barrier that has moved.
A boat will be positioned at the mouth of Emerald Bay to inform the public of project
activities and provide information on when the bay will open.
Overnight boaters in Emerald Bay will be informed of the temporary boat traffic control
to allow departure prior to the start of work.
To the extent possible, all installation and removal activities will be scheduled outside of
the high recreation period between the Memorial Day and Labor Day weekends.
TRANSPORTATION/TRAFFIC
MITIGATION MEASURES TRANS-1: Securing Barriers
Bottom barriers will be checked routinely to inspect and re-secure any bottom barriers
that move or start to billow as gas accumulates under them.
