Comments pertain to the "Pleasant Harbor Golf and Marina Resort Neighborhood Water Supply Program" (NWSP), and the incorporated 'Pleasant Harbor Golf and Marina Resort Ground Water Monitoring Plan' (GMP) memos, both dated February 25 zOtO. Jefferson County Environmental Health offers the following comments in direct response to the two memos as presented: Pleasant Harbor Golf and Marina Res_ort Neishborhood Water Supplv Proeram 1. Monitoring Plan: The NWSP memorandum refers to the project site as not being located in a High Risk SIPZ Zone. Just to clarify, we have updated our seawater intrusion zone GIS mapping with the water quality information submitted by John Pearch in his Hydrogeologic Memo Part 1, 2 and attachments, dated January 14th 2010. For items (a), (b), (d), and (i), indicate where these monitoring activities will be conducted. Will any of these activities occur at offsite wells? For example, will you be installing flow meters on offsite wells per item (b), or do you mean the onsite monitoring wells? a a a a For item (f), please support this assertion. For item (g), more information is needed. What hydrogeological analysis are you referring to? ls it a delineation of the unconfined ("sea level") aquifer? ln any case, who will be conducting the analysis and how will the data be provided? 2. We surmise that for (d), you are referring to the GMP's network of eight wells presented in Figure 1. For the (five) wells where water quality will be sampled it seems the samples should be taken at a depth that will give an early indication of seawater intrusion. ls this plan for monitoring wells adequate both in number of wells and frequency of sampling to allow for early detection of a "potential widespread lateral sea water intrusion" as J. Pearch has referenced. 3. Recharge areas: You indicate that the "identification of an impact" is in the county's SIPZ program. Please be specific and define the identification of an impact rather than simply referencing the SIPZ program, a 4. As a result of John Pearch's report, high risk SIPZ zones have been created on Black Point Peninsula that impact future development reguirements. You indicate that Pleasant Harbor will "set aside recharge areas to mitigate an impact scenario". Please clarify what you mean by this statement, 5. lnitial Mitigation Measures: ln the event of an impact from seawater intrusion, you intend to implement "a plan to mitigate". Such a plan should be described in greater detail. Lowering pumping rates or adding points of withdrawal should be included as a subsection of the program and quantified. a a a a 6. Water Supply Replacement: The Neighborhood Policy required by Jefferson County is not intended to circumvent state water laws or any anti-degradation requirements. The replacement strategy is unlikely to mitigate continued impacts to the unconfined aquifer, especially if the measures described in paragraphs 2 and 3 have already been unsuccessful. We concur with all of John Pearch's comments /recommendations in reference to this section with specific emphasis as follows: o 4 (a) "Pleasant Harbor should pay the cost of hooking up and maintaining a water supply to the impaired individual and that the homeowner's responsibility will be limited to the cost that the homeowner would have spent on electricity running their old system." o 4 (b) "Ecology recommends that all wells be included on the Black Point Peninsula as long as they are completed in the Sea Ievel aquifer. However, if there is excess of 10 neighboring residents who ask Pleasant Harbor to sample their well, Pleasant Harbor should choose only 10 wells that are appropriately located between the proposed withdrawal and the coast, and not focus on one specific area. This will help to evaluate if a widespread lateral sea water intrusion occurs." Is there a plan for Ecologr to "delineate the area of influence?" o 4 (b) "Ecology also recommends in the case if any particular neighboring well that experiences a 10o/o increase in chloride but is still below 100 mg/L, that same well should be sampled at least two additional months following. This will provide a much clearer picture of potentialwidespread lateral sea water intrusion." o "Ecology strongly recommends that any decrease in frequency of monitoring should only occur 10 years after the resort reaches full build out." Pleasant Harbor Golf and Marina Resort Ground Water Monitoring Plan As stated above we believe that the monitoring program should be extended to a period "beyond full build out." General Comments: We recommend that the two memos be combined as one cohesive monitoring plan (neighborhood and groundwater) for clarity and consistency. ln addition, offsite wells designated for monitoring should be located and identified, and a recorded notice to title be executed to allow agency and Resort access for the purpose of implementing the plan. a There is an inactive Group B public water supply (K and P Oyster Company WS# 23601 f ) that is known to have nitrate levels in excess of State maximum contaminant levels. The owner is Ken Gaul, APN 502153032. lt seems this should be considered as a part of a monitoring plan. a ls Pleasant Harbor setting aside sufficient water right to supply full build out within the high risk SIPZ, should this be necessary, or are they relying exclusively on the potential transfer of water rights from the existing senior rights? lf senior water rights show degradation, is it possible that Statesman would have to prove their water system is not the cause vs. the other way around as stated? We have concerns that the assessment does not address how low rainfallyears would affect assumptions. What are the drought contingency plans? Respectfully, Susan Porto Environmental Health Specialist 3 Jefferson County Public Health a a a SUBSURFACE GROUP LLC PMB 154, 1992 S Elger bay Road.

This memorandum provides some additional information and clarifies some of initial responses. We provide the following responses: Pleasant Harbor Golf and MarinaNeighborhood Water Supply Proeram 1.

Our proposed monitoring well MW-8 is just or outside of the boundary. Our water supply wells will be over 1,800 away from the edge of the protective zone. It is my understanding of that 1,000 protective zone, if the proposed water supply well is outside no new measures are necessarv.

The analysis reports are attached. I believe no further action on our part is Thank you for your response to my comments. I will have to rely your expertise to adequately address the concerns related to the of this project on the aquifer. I also understand that Ecology has ready reviewed this project and approved the water rights. I've limited accordin - Susanres Your statements in this regard were , "The existing well has supplied water at similar to proposed rates with no adverse impacts (chlorides = zero." I don't understand how a pump test can be equated to "similar rates" that this project.are SUBSURFACE GROUP, LLC sG0601-02 Memorandum to Statesman Corporation December 1,2010 Page2 d) The hydrogeologic analysis referred to is presented in our Draft Water Supply and Groundwater Impact Analysis Report dated December 17, 2008. That report contains a narrative of our understanding of the aquifer and aquifer conditions, as well as supporting water level and pumping test data. 2. The wells described in Item (d) and shown on Figure I of the Monitoring Plan map cover the resort, concentrating on the borders of the property. The intent is to monitor groundwater drawdown, which given sufficient drawdown for an extended period of time is the principle indicator of the potential for sea water intrusion. It is our opinion that the number of wells is more than adequate. The depth of the wells is also adequate to monitor for these purposes. In addition, the American Campground well is an exceptionally deep well; monitoring of groundwater quality from this well will provide an understanding if upwelling of saltwater could be occurring. As the project will be introducing more water into the aquifer, we do not believe that a "potential [for] widespread lateral sea water intrusion" exists; however, we have built a monitoring program and contingencies to address the concerns of the community and to protect community and resort itself. 3. Recharge Areas: We consider an 'impact' as 'High Risk' levels presented in the County's SIPZ identify impacts in paragraph 4(b) of the attached F Water Supply Program. Our opinions regarding the impact are summarized on Page 18 of our report cited above. 4. As noted in pages 16 through l8 of our December 008 report, the hydraulics of the resort will be such that there will be more water recharge to the aquifer This is largely a function ofduring operation ofthe resort than presently collecting water from the roof tops and roadways and infiltrating it before the water can evaporate be consumed by vegetation. Infiltration galleries will be constructed beneath the golf course fairways that will be used to infiltrate excess stormwater. These galleries will be placed around the resort to enhance aquifer recharge. Attached is a preliminary facility map in which we have set aside recharge areas as infiltration galleries. 5. At this time there have been many mitigation measures already incorporated into a water supply plan that shows a net benefit to the aquifer. Beyond all of those measures, there are options to add additional wells that will pump at lower individual rates, to focus groundwater recharge to areas of concern, or even to treat surface water. In our opinion these are suitable mitigation measures for I'm not familiar enough with the details of your project to adequately comment on this. My overall concern is whether you have planned adequately drought years and the limitations of recharge SUBSURFACE GROUP, LLC sG0601-03 Memorandum to Statesman Corporation December 1,2010 Page 3 planning purposes, and the appropriate measures will be taken to protect the community's and resort's water supply should a situation arise. 6. Water Supply Replacement: a) We are not aware of the mitigation plans presented to be in violation of any state law or policy. Based on our understanding of the hydrogeology beneath Black Point, the monitoring and mitigation plans offered by the resort are proactive and conservative. b) As we have discussed with Eco other conditions of the water are unnecessarily diffi cult to c) The monitoring influence from the water supply data from the of the drawdown L 2. ite wells will be identified as the proj The Gaul well can be considered for mon with existing poor water quality may not monitoring plan.

G2.30436 February 24,2010 The following four elements to protect existing water rights concern water right application no. G2-30436: 1. Monitorinq Proqram 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. 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 wil! 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. This program will be continued for five years or until the resort has achieved fu!l build-out, whichever is longer. 2. Recharqe Areas. Pleasant Harbor will set aside recharge areas to mitigate an impact scenario or provide access (connect) to neighboring parcels to (0 (i) Neighborhood Water Supply Program - Page 1 the Pleasant Harbor water system in the event of a problem with increased chlorides (we also have the option to drillthem a new well). The identification of an impact is already presented in the County's SIPZ program. 3. lnitial Mitiqation Measures. lf 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 Supplv Replacement. ln 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. lf 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 wel!, 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 15o/o that results in levels above 200 mg/l; or levels increase by 30o/o that results in levels above 100 mg/l over a 12-month period (250 mg/l 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 Neighborhood Water Supply Program - Page 2 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 ful! 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) lf 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.
