SUMMARY: The
Board will accept public comment and take action on the April through June 2010
Quarterly Water Supply Strategy and Budget for California American Water’s (CAW)
Main and Laguna Seca Subarea Water
Distribution Systems (WDS). The proposed
budget, which is included as Exhibits 20-A
and 20-B, shows monthly production by
source of supply that is required to meet projected customer demand in CAW’s Main
and Laguna Seca Subarea systems, i.e.,
Ryan Ranch, Bishop, and Hidden Hills, during the April through June 2010
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 Carmel River Basins.
Exhibit 20-A shows the anticipated production by CAW’s
Main system for each production source and the actual production values for the
water year to date through the end of February 2010. Please note that the anticipated production
values assume that CAW annual Main system production will not exceed 14,868
acre-feet (AF), including 3,583 AF from the coastal subareas of the Seaside Groundwater
Basin and 11,285 AF from the Carmel River
Basin. The
total from the Carmel River Basin is consistent with State Water Resources
Control Board (SWRCB) Order No. 95-10 and the total from the Seaside Groundwater
Basin is consistent with the Seaside Basin adjudication decision. Both of
these limits are subject to change, pending future regulatory actions. For the purpose of this budget, it is conservatively
assumed that normal inflow conditions will occur.
Exhibit 20-B shows the anticipated production by
CAW’s Laguna Seca Subarea system for each production source and the actual
production values for the water year to date through the end of February 2010. Please note that the anticipated production values
assume that CAW’s annual Laguna Seca Subarea systems’ production will not
exceed 246 AF from the Laguna Seca Subarea of the Seaside Groundwater
Basin. This total is consistent with the Seaside Basin adjudication decision.
If
the rainfall and runoff amounts in the Carmel
River Basin are less than projected
under the assumed normal-year conditions, then monthly production from the Seaside Basin may need to be increased. Similarly, if rainfall and runoff amounts are
greater than projected and streamflow in the Carmel
River exceeds the instream flow
requirements specified by the National Marine Fisheries Service (NMFS),
additional water will be diverted by CAW for injection into the Seaside Groundwater Basin
as part of the Phase 1 ASR Project. The
amount of water diverted from the Carmel
River that is treated and delivered
for injection will also depend on customer demand, the available production
capacity of CAW’s wells in the Carmel Valley at that time, and available injection capacity
of the ASR wells in the Seaside
Basin
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
20-C, Quarterly Water Supply Strategy
Report: April – June 2010.
BACKGROUND:
The Quarterly Water Supply Strategy and Budget pertains to production
within CAW’s Main and Laguna Seca Subarea
systems for the three-month period of April, May and June 2010. Staff from the District, CAW, California
Department of Fish and Game (CDFG), and NMFS cooperatively developed this
strategy on March 11, 2010. Based on
current reservoir and Carmel Valley Alluvial Aquifer storage conditions, and the
significant rainfall that has occurred to date, it was agreed that “normal”
year inflows would be used to assess CAW’s operations and set monthly
production targets for CAW’s systems.
To
meet customer demand in its main system, CAW will produce approximately 106, 0,
and 0 AF of groundwater from its wells in the Upper Carmel
Valley during April, May,
and June 2010, respectively. Similarly,
CAW will produce approximately 1,086, 998, and 991 AF of groundwater from its
wells in the Lower
Carmel Valley
during April, May, and June, respectively.
Of this production, it is assumed that 186 AF would be diverted from the
Carmel River
and injected into the Seaside
Groundwater Basin
in April 2010. It is currently projected
that river flow will not be sufficient in May to allow operation of ASR; the
permitted diversion season ends May 31.
It
was also agreed that, subject to rainfall and runoff conditions in the Carmel River Basin,
CAW would produce 100, 400, and 500 AF from the Coastal Subareas of the Seaside Basin, respectively, during this period. The June production from the Coastal Subareas
of the Seaside Groundwater Basin
would be comprised of 275 AF of native groundwater, combined with 225 AF of
storage recovered from ASR. In addition,
it was also agreed that CAW would produce 17, 24, and 27 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 CAW would not
divert any water from San Clemente Reservoir through the Carmel Valley Filter
Plant during this quarter. CAW 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.
