SUMMARY:
The Board will accept public comment and take action on the October
through December 2012 Quarterly Water Supply Strategy and Budget for California
American Water’s (Cal-Am’s) Main and Laguna Seca
Subarea Water Distribution Systems (WDS).
The proposed budget, which is included as Exhibits 13-A and 13-B,
shows monthly production by source of supply that is required to meet projected
customer demand in Cal-Am’s Main and Laguna Seca
Subarea systems, i.e., Ryan Ranch, Bishop,
and Hidden Hills, during the October through December 2012 period. The proposed strategy and budget is designed
to maximize the long-term production potential and protect the environmental
quality of the Seaside Groundwater and
Exhibit 13-A shows the anticipated production
by Cal-Am’s Main system for each production source
and the actual production values for the water year to date through the end of
August 2012. Please note that the anticipated
production values assume that Cal-Am’s annual Main
system production for Water Year (WY) 2012 will not exceed 12,856 acre-feet
(AF), including 2,669 AF from the Coastal Subareas of the Seaside Groundwater
Basin, 131 AF from ASR Phase 1 recovery, 300 AF from the Sand City Desalination
Plant, and 9,756 AF from the Carmel River Basin. The total from the
Exhibit 13-B shows the anticipated production
by Cal-Am’s Laguna Seca
Subarea systems for each production source and the actual production values for
WY 2012 to date through the end of August 2012.
Please note that the anticipated production values assume that Cal-Am’s annual Laguna Seca Subarea
systems’ production will not exceed 147 AF from the Laguna Seca Subarea of the
Seaside Groundwater Basin. This total is
consistent with the
RECOMMENDATION:
The Board should receive public input, close the Public Hearing, and
discuss the proposed quarterly water supply budget. District staff recommends adoption of the
proposed budget. The budget is described
in greater detail in Exhibit 13-C,
Quarterly Water Supply Strategy Report: October –December 2012.
BACKGROUND:
The Quarterly Water Supply Strategy and Budget pertains to production
within Cal-Am’s Main and Laguna Seca
Subarea systems for the three-month period of October, November, and December
2012. Staff from the District, Cal-Am,
the California Department of Fish and Game (CDFG) and the National Marine
Fisheries Services (NMFS) cooperatively developed this strategy on September
10, 2012. Based on current reservoir and
Carmel Valley Alluvial Aquifer storage conditions, and the low rainfall that
has occurred to date, it was agreed that “dry” inflow conditions will occur
through December 2012. Thereafter, the
rainfall-to-date through November 2012 will be used to select a Water Year Type
for the following quarter, so as to more accurately assess Cal-Am’s operations and set monthly production targets for Cal-Am’s systems from January through September 2013.
To
meet customer demand in its main system, Cal-Am will produce approximately 0 AF
of groundwater from its wells in the Upper Carmel Valley during October,
November, and December 2012. Similarly,
Cal-Am will produce approximately 628, 558, and 705 AF of groundwater from its
wells in the Lower Carmel Valley during October, November, and December 2012,
respectively. The permitted diversion
season for ASR begins again on December 1, which is during this first quarter
of WY 2013. Diversions to storage for
ASR Phase 1 will begin after December 1st, whenever flows in the
river are legally adequate to do so. For
planning purposes staff scheduled 145 AF of diversions to ASR storage, based on
the long-term average diversion rate predicted by the Carmel Valley Simulation
Model (CVSIM) for that month.
It
was also agreed that, subject to rainfall and runoff conditions in the Carmel
River Basin, Cal-Am would continue to produce water from the Coastal Subareas
of the Seaside Basin during this period.
Cal-Am is projected to produce 369, 350, and 250 AF of native
groundwater from the Seaside Basin in the months of October, November, and
December 2012, respectively. A
concurrent production goal is to complete the recovery of all of the 131 AF of
water previously stored by Water Project 1 (ASR Phase 1) in WY 2012, within the
month of October 2012, which is the first month of the first quarter of WY
2013. There is also a goal of producing
an additional 25 AF of treated brackish groundwater from the Sand City Desalination
Plant in each of these three months. In
addition, it was also agreed that Cal-Am should produce only 14, 10, and 8 AF
of groundwater from its wells in the Laguna Seca Subarea for its customers in
the Ryan Ranch, Bishop, and Hidden Hills systems during October, November, and
December 2012, respectively. Lastly, it
was agreed that Cal-Am would not divert any water from San Clemente Reservoir
through the Carmel Valley Filter Plant during this quarter. Cal-Am will operate its wells in the Lower
Carmel Valley in a downstream-to-upstream order. If actual natural river inflows are less than
projected for the budget period, the group will reconvene and adjust the LPD
release rates accordingly.
Rule
101, Section B of the District Rules and Regulations requires that a Public
Hearing be held at the time of determination of the District water supply
management strategy. Notice of this
Public Hearing has been published in The Herald. Adoption of the quarterly water supply
strategy and budget is categorically exempt from the California Environmental
Quality Act (CEQA) requirements as per Article 19, Section 15301 (Class
1). A Notice of Exemption will be filed
with the Monterey County Clerk's office, pending Board action on this item.
