SUMMARY:
The Monterey Peninsula Water Management District (MPWMD or District) and
California American Water (Cal-Am) are preparing to initiate Water Year (WY)
2011 injection operations at the Santa Margarita Phase 1 Aquifer Storage and
Recovery (ASR) site on
Phase 1 Site:
The work at the Santa Margarita Phase 1 ASR site includes a focus on
design, engineering and permitting assistance for acquisition of new land area
to accommodate new water delivery lines to and from other ASR facility sites to
the new Chemical/Electric building at this site. These additional lines and 40-feet wide
easement are needed to facilitate disinfection, circulation and disposal of
water within an expanded ASR system, consistent with the Cal-Am Coastal Water
Project plans. As part of this work, the
site entry, driveway circulation pattern and backflush percolation pit will be
redesigned to accommodate the new pipelines and future uses associated with
them. In addition, it is planned to
complete installation of permanent wellhead automated controls at the site ASR
wells, and permanent electrical control equipment inside the new building
during this period.
Phase 2 Site:
The work at the Seaside Middle School Phase 2 ASR site includes
procurement of well pumping and wellhead piping equipment for use in backflushing
operations at the Seaside Middle School ASR test well that was constructed in
Summer 2010. In addition, work at this
site will include formal “baseline” injection testing of this new ASR well. The Seaside Middle School ASR test well was
installed under an accelerated schedule in response to the October 20, 2009
adoption of State Water Resources Control Board Cease and Desist Order WR
2009-0060. It is the District and
Cal-Am’s understanding that this work will comply with Condition 5 of this Order,
which requires Cal-Am to implement “one or more small projects, that when taken
together, total not less than 500 afa [acre-feet per annum] to reduce unlawful
diversions from the river”. Condition 5
further requires that the projects shall be implemented within 24 months of
entry of the Order. The current
estimated yield for a full Phase 2 ASR Project consisting of two ASR wells at
this site is 1,000 acre-feet per year.
RECOMMENDATION:
District staff recommends authorization to amend the existing contract
agreement with PWR for the hydrogeologic and engineering technical services
described in Exhibit 2-A, for a not-to-exceed amount of
$734,737. Of this amount, an estimated
$373,750 will be from direct reimbursement by Cal-Am under agreements for Phase
1 operation and maintenance and Phase 2 test well installation. If approved, staff will process an amendment
for this amount in order to continue work on both the Phase 1 and 2 ASR project
elements without delay. The requested
funding authorization includes a 10% contingency amount which would only be
utilized based on written request and authorization by the District.
BACKGROUND:
The proposed work described in this item represents a continuation of
past accomplishments on the Phase 1 and Phase 2 ASR Projects, with technical
assistance from PWR. Given the current
knowledge base and capabilities of the PWR staff that have been assigned to
this work, combined with the desired fast-track schedule for the Phase 2 ASR
component, District staff believes that it is most prudent and efficient to
extend the existing contract with PWR, to avoid delays and duplicative work on
the projects. PWR is prepared and able
to initiate this work in accordance with the current requested schedule, and
has successfully accommodated other past short-notice schedule changes on both
the Phase 1 and 2 ASR project work elements.
PWR’s hourly fee schedule is among the lowest of rates that District
staff is aware of from firms doing comparable technical work in this area, or
from other firms with which the District has recently retained for a similar
level of professional services. This in
part, led to the original contract award by competitive solicitation to PWR
(formerly Padre Associates) for the development of the first full-scale ASR
well at the Phase 1 ASR site. In
addition, PWR currently provides technical assistance to CAW for the ASR
component of the proposed Coastal Water Project. By retaining PWR for this work, there is
greater assurance that the District’s and CAW’s ASR Project plans will be well
coordinated and cost effective.
