SUMMARY – Seaside Groundwater
Basin: The Sustainable Groundwater Management Act (SGMA)
established a process for local agencies to request that the Department of
Water Resources (DWR) revise the boundaries of existing groundwater basins
or subbasins, including the establishment of a new subbasin. The Basin Boundary Emergency Regulation was
developed through an extensive stakeholder outreach process and was adopted on
October 21, 2015. The provisions of the emergency regulation go into effect on
November 16, 2015.
On November 19, 2015 District staff met with representatives of the
Seaside Basin Watermaster, California American Water
Company, Marina Coast Water District, and Monterey County Water Resources
Agency to discuss a proposal for boundary modification. Then on December 14,
2015 the District’s Water Resources Division Manager sent out the proposal for
comment from the same agencies.
The District submitted a formal Initial Notification to DWR on February
12, 2016 – notification intended to be preliminary to signal that a
modification request may occur. It served to notify other
local agencies, public, and the department.
The proposal can be summarized as follows: The Bulletin 118 boundary is shown in the
first attachment (Exhibit 17-A) and is
labeled “Salinas Valley Seaside Area”. The modification that the group
achieved consensus on is shown in the second attachment (Exhibit 17-B). This modification inserts the
adjudicated Seaside Basin boundary and removes the remainder area in the
southwest portion of the DWR boundary, as this area is not hydrogeologically
linked to the aquifer system in the Seaside Basin. The remainder area to
the north of the Seaside Basin has been renamed “Salinas Valley Marina Area”,
consistent with our discussion. The DWR’s basin modification application
requests that a map be provided to show the proposed basin boundary
modification, which is depicted in Figure 1 (Exhibit 17-B). Note that the subbasin
names are abbreviated on this map, but will be described with their full names
per Bulletin 118 as part of the application. In addition, the DWR’s
application requests that a map showing all local agency boundaries in the
affected area of the boundary modification also be provided. Accordingly,
we have prepared the map as depicted in Figure 2 (Exhibit 17-C). Figure 1 and Figure 2 were again
distributed to the group of interested stakeholders for comment on March 15,
2016.
The District submitted the Basin Boundary
Modification Request March 31, 2016. It
will be deemed “SUBMITTED” signifying the submission is believed to be
complete and the requesting agency is officially submitting the package to DWR
for a completeness review. It will be
deemed “COMPLETE” once DWR has reviewed the submission package for
substantial compliance with the requirements and the 30-day Public Input Period
begins. Public input must be made in compliance with the requirements of
§343.12 of the regulation and submitted to the Basin Boundary Modification
System as a "Comment" to the "Complete" modification
request submission. All submitted
information will be public accessible through DWR web site.
The District was notified on April 5th
that there are two issues DWR wants corrected in order to deem the application “complete”:
1. Support letters from ¾ of the affected local
agencies and water systems, and
2. Discussion regarding removal of the southwest
area of the Bulletin 118 Seaside boundary.
The second item will be satisfied because the
discussion is included in the application materials and staff just needs to
point out to the reviewer where that is located. The first item, however,
is more problematic in that it could be a challenge to get support letters
drafted through the various local entities. Staff has contacted the DWR
reviewer to see if it might be possible to just get support letters from the
MPWMD and Watermaster boards as a means to satisfy
this requirement.
SUMMARY –
Carmel Valley Alluvial Aquifer: On February 29th, the General
Manager sent an inquiry jointly to California Department of Water Resources
(DWR) and State Water Resources Control Board (SWRCB) staff, describing an
inherent conflict in how DWR and SWRCB view the Carmel River Alluvial Aquifer
and how it will be affected by the Sustainable Groundwater Management Act
(SGMA). We had mentioned it briefly to DWR staff on a few occasions, but
at this time summarized the issue in a single page, attached as Exhibit 17-D.
The Water Management District’s conclusion is
that what DWR refers to as the Carmel Valley Groundwater Basin in Bulletin 118
has been determined to be surface water by the SWRCB. This led to
several questions:
·
Should
the Carmel River aquifer be exempt from SGMA?
·
What is
the best way to exempt it – by letter from DWR or by removal from Bulletin 118?
·
If by
removal from Bulletin 118, should it be done through the DWR Basin Boundary
Modification Request System by formal request by March 31st, or some
other method?
·
Would a
meeting between DWR, SWRCB, and the District (the GSA) be necessary to discuss
this matter?
On March 16, 2016 DWR staff stated “I don't
think Monterey would have to take any action. Although I doubt we will
deal with this through a basin adjustment, DWR would have the ability to make
any adjustments without having Monterey submit since this is a special technical
issue.” We also learned that there was
one other basin in the State with a similar issue, and 4-5 others with similar
problems for a portion of the basin.
We also informed DWR that their Bulletin 118
boundary for the Carmel River Basin were outdated and inconsistent with current
knowledge. DWR indicated that it is
currently updating the Department defined modifications to basin boundaries
(Administrative Adjustments) and will include the District’s changes as part of
that set. On March 29th, the
District forwarded GIS shapefiles and SWRCB Order 95-10 describing the geologic
setting as surface water flowing in a known and definite channel underground.
We have been told to expect a letter or
notification from DWR that the Carmel River Basin is exempt from SGMA and will
not require a Groundwater Sustainability Plan.
