SUMMARY: District Rule 162 specifies the regulatory water
production targets that are used in the District’s Expanded Water Conservation and Standby Rationing Plan to trigger
higher stages of water conservation to ensure California American Water (CAW or
Cal-Am) compliance with the production limits set by the State Water Resources
Control Board (SWRCB) Order 95-10 and the Seaside Groundwater Basin
adjudication decision, as amended.
Specifically, Table XV-1 in Exhibit 10-A
specifies monthly and year-to-date at month-end targets for all CAW systems
that derive their source of supply from the Monterey Peninsula Water Resource
System (MPWRS). Similarly, Table XV-2 in
Exhibit 10-A breaks out monthly
and year-to-date at month-end targets for CAW systems that derive their source
of supply from the Laguna Seca Subarea of the
Rule 162 authorizes modifications to Tables XV-1 and
XV-2 to account for changes in the amount of water that CAW is allowed to
divert from the Carmel River System under SWRCB Order 95-10 and the amount of
water that CAW is allowed to produce from the Seaside Groundwater Basin under
the Seaside Basin Decision, as administered by the Seaside Basin
Watermaster. Any modifications to these
tables must be made by Board resolution.
On December 2, 2009, the Seaside Basin Watermaster
Board approved a 10% reduction in the operating yield of the Seaside Basin for
the October 1, 2009 through September 30, 2010 period (Exhibit 10-B). This reduction had been ordered by the Court
in the adjudication decision that was issued in March 2006 and amended in
February 2007, and will occur every three years until the operating yield is
equivalent to the natural safe yield, or replenishment supplies are
developed. The 10% reduction in the
basin operating yield requires CAW to reduce its pumping from the Coastal
Subareas of the Seaside Groundwater Basin by an additional 104 acre-feet (AF)
in Water Year (WY) 2010. Similarly, the
10% reduction in the basin operating yield requires CAW to reduce its pumping
from the Laguna Seca Subarea of the
Resolution 2009-17 (Exhibit 10-A) modifies Table XV-1 and XV-2 of Rule
162 to account for the 10% reduction in the Seaside Basin operating yield and
inclusion of the 496 AF carryover credit from WY 2009 that was approved by the
Seaside Watermaster Board on December 2, 2009, for WY 2010.
Note that the recommended changes do not
include any revisions to Cal-Am’s production targets due to State Water
Resources Control Board (SWRCB) Order WR 2009-0060 that was adopted by the
SWRCB on October 20, 2009, and was stayed by the Monterey County Superior Court
on November 3, 2009. For illustration
purposes, the reductions in Cal-Am’s diversions from the
RECOMMENDATION: District
staff recommends adoption of Resolution 2009-17 (Exhibit 10-A) modifying
Rule 162.
