SUMMARY: The Board will accept public comment and take
action on the January through March 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 Exhibit
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 January through March 2012 period. The proposed strategy and budgets are
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 Water Year (WY) 2012 to date through the
end of November 2011. Please note that the anticipated production
values for customer service assume that Cal-Am’s
annual Main system production for Water Year (WY) 2012 will not exceed 12,977 acre-feet
(AF), which is comprised of 2,669 AF from the Coastal Subareas of the Seaside
Groundwater Basin, 300 AF from the Sand City Desalination Plant, and 10,008 AF
from the Carmel River Basin (comprised of 1,117 AF of ASR Phase 1 recovery and 8,891
AF of direct diversion). The total from
the

Subarea systems for each production source and the actual production values for
WY 2012 to date through the end of November 2011. Please note that the budgeted production
values assume that Cal-Am’s annual Laguna Seca Subarea systems’ production for WY 2012 will not
exceed 147 AF from the Laguna Seca Subarea of the Seaside Groundwater
Basin. This total is consistent with the
If
streamflow in the Carmel River exceeds the instream
flow requirements specified by National Marine Fisheries Service (NMFS), a
portion of the “excess” groundwater may be diverted from the Carmel River
Alluvial Aquifer by Cal-Am for injection into the Seaside Groundwater Basin as
part of the Phase 1 and Phase 2 ASR Project.
The amount of water diverted from the Carmel River Alluvial Aquifer that
is treated and delivered for injection will also depend on customer demand and Cal-Am
production system availability at that time.
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
budgets are described in greater detail in Exhibit 13-C, Quarterly Water Supply Strategy
Report: January – March 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 January, February, and March 2012. Staff from the District, Cal-Am, and California
Department of Fish and Game (CDFG), cooperatively developed this strategy on
December 8, 2011. Staff from the
National Marine Fisheries Service (NMFS) were unable to attend, but were
consulted by phone for their approval. Based
on current reservoir and Carmel River Alluvial Aquifer storage conditions, the higher
than average base river flows in October and November 2011,
it was agreed that “normal” year inflows would be used to conservatively assess
Cal-Am’s operations and set monthly production
targets for Cal-Am’s systems.
To
meet customer demand in its main system, Cal-Am intends to avoid producing any groundwater
from its wells in the Upper Carmel Valley during January through March 2012,
and will focus instead on producing approximately 1,020, 1,037, and 1,202 AF of
groundwater from its wells in the Lower Carmel Valley during January, February,
and March 2012, respectively. Of this
production, it is assumed that 230, 300, and 340 AF would be diverted from the
Carmel River Alluvial Aquifer and
injected for storage into the Seaside Groundwater Basin during the January
through March 2012 period. These latter
targets are based on the long-term average diversion rate for Phase 1 and half
of the Phase 2 ASR capacity, predicted by average values from 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 produce no water from the Coastal Subareas of the
Seaside Basin during this period, except for 25 AF per month from the Sand City
Desalination Plant, and would allow the basin to naturally recharge. In addition, it was also agreed that Cal-Am
would plan to produce only 7, 6, and 9 AF of groundwater from its wells in the
Laguna Seca Subarea for its customers in the Ryan Ranch, Bishop, and Hidden
Hills systems during this period. 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 inflows are more or less than
projected for the budget period, the group will reconvene and adjust the diversion
and 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.
