APPLICATION NO. G230436
February 24, 2010
The following four elements to protect existing water rights concern water right
application no. G2-30436:
1. Monitoring Program
This monitoring program meets and exceeds all requirements for a High Risk
SIPZ zone as defined by Jefferson County. Though Pleasant Harbor is not
located in a high-risk zone, the resort has committed these resources to assure
its neighbors and the County that the aquifer is being wisely used and protected.
A copy of the Pleasant Harbor Groundwater Monitoring Plan, as revised
February, 2010, is attached and incorporated herein ("monitoring plan").
The following summarizes the monitoring program
(a) Water quality samples will be collected on a quarterly basis.
(b) Flow meters will be installed.
(c) Pleasant Harbor will have a very thorough network of monitoring
wells (8) which will be used to document draw down conditions in
the aquifer.
(d) The network will include monitoring aquifer salinity conditions on
one-half hour increments.
(e) The locations of Pleasant Harbor wells will be located over 1,000
feet from any neighboring well or the shoreline.
(f) The existing well has supplied water at similar to proposed rates
with no adverse impacts (chlorides = 0).
(g) Hydrogeologic analysis is completed.
(h) Pleasant Harbor will route all site water into the aquifer in such a
manner that the aquifer will actually be receiving more water than
under existing natural conditions.
(i) This program will be continued for five years or until the resort has
achieved full build -out, whichever is longer.
2. Recharge Areas. Pleasant Harbor will set aside recharge areas to
mitigate an impact scenario or provide access (connect) to neighboring parcels to
Neighborhood Water Supply Program - Page 7
the Pleasant Harbor water system in the event of a problem with increased
chlorides (we also have the option to drill them a new well). The identification of
an impact is already presented in the County's SIPZ program.
3. Initial Mitigation Measures. If the monitoring program and evidence of
increased chlorides in neighboring wells show a probable salt water intrusion
impact on the wells from Pleasant Harbor's withdrawal of groundwater, Pleasant
Harbor will implement a plan to mitigate or minimize such impact by considering
lower pumping rates and/or adding points of withdrawal, in addition to recharge
as provided in paragraph 2 above.
4. Water Supply Replacement. In Jefferson County's approval of the FEIS
completed for Pleasant Harbor, Jefferson County has included condition P, the
Neighborhood Water Policy, which requires Pleasant Harbor to provide access to
its water system by any neighboring parcels if salt water intrusion becomes an
issue for neighboring wells on Black Point. Statesman proposes to expand and
define the terms of this policy as a condition of the water rights, as follows.
If the initial mitigation measures stated in paragraphs 2 and 3 above do not
correct or resolve the salt water impacts detected by the monitoring program,
Pleasant Harbor will offer at its cost sufficient mitigation and/or replacement
water for potable water for any existing home on a well that has an increase in
chloride levels as follows and under the following conditions:
(a) The neighboring resident's well is within the radius of influence of
the Pleasant Harbor wells. Until such time that Ecology has
sufficient evidence to delineate this area of influence, wells located
on the Black Point Peninsula in the same aquifer as Pleasant
Harbor's wells are covered by this neighborhood policy.
(b) The well owner provides conclusive evidence that, over a
statistically relevant period of time, chloride levels have increased
over chloride levels in the well prior to Pleasant Harbor's use of
groundwater, including but not limited to, evidence that the increase
in chloride levels is from the Pleasant Harbor groundwater use and
not from the construction of the well owner's well, and the data from
the monitoring program is consistent with the increase in chlorides.
As a default standard, Pleasant Harbor will provide an alternative
water supply if chlorides in a well exceed baseline (pre -Pleasant
Harbor groundwater use) by 15% that results in levels above 200
mg/I; or levels increase by 30% that results in levels above 100
mg/I over a 12 -month period (250 mg/I is the SDWA standard).
(c) Pleasant Harbor has the right to request additional evidence from
the resident showing that the Pleasant Harbor groundwater
withdrawal is the cause of the increase in chlorides if the increase

is isolated to one well, the increase is likely caused by another
problem, and the only reasonable water replacement is a new well.
(d) The monitoring program will be continued for five years or until the
resort has achieved full build -out, whichever is longer. After this
period, the level of monitoring may be decreased unless there is
significant data showing increased chlorides, and Ecology
determines the monitoring program must be continued.
(e) If Pleasant Harbor provides replacement water from the Pleasant
Harbor system, it may apply for consolidation of the water rights
under RCW 90.44.105. The well owner will waive any claims
against Ecology or against Pleasant Harbor for any impairment of
the water right if Pleasant Harbor offers a reasonable alternative
source as provided above.
