Read how the City of DuPont and their engineers were concerned, even back before it started, about the mining well that draws 40,000,000 gallons of water a day from our aquifer.

GORGENSEN ADMINISTRATOR ROBERT L. RIECK RUSSELL C. HARPER MARIETTA E. BUDACK . RAY L. MILLER August 6, 1990 Mr. Pat Lee, Director Southwest Regional Office Department of Ecology 7272 Cleanwater Lane Olympia, WA 98504 Dear Mr. Lee: Before Ecology issues a temporary water right to Lone Star Northwest, I want to clarify with you the citys position regarding provision of water to Lone Star Northwest for operation of their proposed surface mine. I also want to know from you how to proceed given the Citys position, as explained below. The Citys initial intention was to review, in the environmental impact statement for the proposed surface mine, consistency of Lone stars proposal with the Citys Water Supply Comprehensive Plan (WSCP). However, because Ecology is considering issuing a temporary water right to Lone Star we feel it prudent to review this issue now, rather than wait until the draft EIS is issued. The proposed p~oject site is within the Citys water service boundary, as delineated both in the citys Water System Comprehensive Plan (dated July 12, 1989), and the environmental impact statement for DuPontss Comprehensive Plan and Land Use Zoning Code (dated May 1985). The city intends to serve water to all users within this service boundary, including Lone Star Northwest should their proposal receive necessary approvals. As explained on page 3 of the WSCP, the DuPont-water service area "includes the area within the city corporate boundaries," and "the future service area boundary· has been established to encompass approximately 4,123 acres~: Lone Star Northwest·ss proposed project site is within this service-area boundary. Though industrially zoned land north of Sequalitchew Creek is within the Citys water service area boundaries, our WSCP did not anticipate an industrial water demand in this area until after the year 2010. Therefore, the water system described in our WSCP was not designed to accommodate water requi~ements for the industrially-zoned area.
  2. 2. The WSCP does, however, recognize that: "Unanticipated future changes to land use or development activity will have to be evaluated for the effect on the planned facilities.1IThe city views the EIS for Lone stars proposal as the mostappropriate arena for evaluating the effect of the proposedproject on the citys planned system. However, we need datafrom the proposed test well to determine how to incorporateLone stars projected water demand into the Citys watersystem. Also, we have yet to determine if the location ofthe proposed well optimizes our long range service needs.The EIS will analyze test-well data, as well developverifiable estimates of the potential water needs of theproposed facility, and review the potential for thewithdrawal to result in adverse environmental impacts.Because we need this information for the EIS, we do not wantto delay issuance of a temporary permit to allow the testwell.Given the fact that the city maintains the right to providewater to all users within the service area boundary, we needto know how to proceed. Please let us know if we need totake any action to insure that the city preserves all rightsto ground water within its delineated service boundaries.We also need to know if additional actions would be requiredto reserve water rights to meet future demand, in accordancewith our WSCP.Please call me or Kari Rokstad at (206) 964-8121, if youhave any questions or comments.

Box 455 Dupont, Washington 98327 (AUG a 199(1 SUBJECT: COMMENTS ON HART CROWSERS WORK PLAN FOR THE LOAN STAR NORTHWEST WATER WELL PROJECT, CITY OF DUPONT, PIERCE COUNTY~ WASHINGTON; G&O #90654 Dear Ms. Rokstad: As per your request, we have reviewed the Work Plan for the Lone Star Northwest Water Well Project, prepared by Hart Crowser and submitted to the Department of Ecology on July 18, 1990. Lone Star Northwest is seeking a temporary permit to drill a 1,200 foot test/production well at their proposed surface mine north of the City of Dupont. This Work Plan addresses concerns about the project expressed by the Department of Ecology in a letter of 27 June 1990 to Hart Crowser. We have discussed the Work Plan with Lori Herman at Hart Crowser. We believe that the Work Plan presents reasonable responses to these concerns, but wish to offer the following comments.Potential for Salt Water IntrusionWe are concerned that monitoring chloride content as per the proposed schedulemay not be sufficient to detect a trend indicating salt water intrusion. If aproduction well is completed, sampling at least quarterly on a long-term basis(longer than 2 years) should be considered.Sufficient water to meet existing/requested water rightsIt is important to note that, because there are a limited number of production wellsin the aquifers of interest (Intermediate and Deep Aquifers as defined in the WorkPlan), it is not known whether these aquifers can supply sufficient water to meetexisting and future needs of the area. This information can only be obtained fromdrilling/testing activities in these aquifers. Information obtained from tests of theCitys Bell Hill No.2 well and Lone Stars proposed initial well could be used toevaluate the long-term developable yield of the Intermediate Aquifer. Similarly,information obtained from drilling/testing activities in the Deep Aquifer(s) isnecessary to eval ua te its potential yield.

However, because there is apparently little or no water quality data for these aquifers available at this time, and because of the implications regarding public health concerns, we suggest that it would be prudent to analyze water quality samples from these aquifers for an extended set of constituents, including volatile and semi-volatile organics and metals as suggested by the Department of Ecology. Please advise if we can be of further assistance in this matter. Very truly yours, GRA Y & OSBORNE, INC. T~ Vj~1v ~ f~ Tony Vivolo, P.E. TV jbeb ."
