RE: Technical Revision request for Star Water Resource, Permit # M- 1977 -522 staging area. It covers approximately 3.16 acres between the reservoir on the west and the backfilled area on the east. Future owners can use this area as an equipment parking and staging area and to stockpile material needed during the development of the reservoir. This area has been graded and graveled using pit run material to prevent erosion. Change #2 This change proposes to include three possible future reservoir facility development envelopes around the reservoir, within which future owners can start reservoir development as soon after purchasing the property as possible. The northeast development area will cover approximately 1.37 acres. The southeast area will cover approximately 1.44 acres, and the southwest area will cover approximately 2.29 acres. These three areas would be used by future owners /developers to install improvements needed for operation of the reservoir (such as pump stations, bank armoring for outlets and inlets, etc.). The current operator, L.G. Everist, is just including this information about possible future development areas in case the property is sold prior to release from the DRMS permit, and in case the future owner wants to get started on the reservoir development immediately (i.e. prior to complete permit release). At this time, these areas have been reclaimed by seeding the non -road areas and grading and graveling the road areas. Change #3 The original Reclamation Plan - Option B, which was chosen by the operator during the adequacy period, explained that there was potentially enough excess material in the west lake area to backfill all of the post -1981 water surface area in the east lake, leaving only approximately 6.10 acres of pre -1981 water surface. As a reminder, the approximately 6.10 acres of pre -1981 water surface was based on the amount of lake area exposed on September 2, 1980, as shown on the photos we provided during the amendment process. Unfortunately, there was not enough excess material in the west lake area to backfill the east lake to its approximately 6. 10 acres of pre -1981 water surface area. So, the operator backfilled as much as possible and is leaving a total of approximately 8.28 acres of water surface in the eastern parcel. This results in approximately 2.18 acres of post -1981 water surface being exposed in the east lake area. L.G. Everist has already submitted (in January-2015) an amendment to their approved Division of Water Resources' Substitute Water Supply Plan to cover the evaporative losses for the approximately 2.18 acres of post -1981 water surface exposed in the Eastern Parcel. Figure E - Reclamation Plan Map (As- Built) shows the groundwater lake area which is to remain in the eastern parcel, based on the September -2014 lake elevation. We have shown the pre -1981 and post - 1981 areas in different colors. The light blue area is the approximately 6.10 acres of pre -1981 lake area, and the dark blue area with wavy lines is the approximately 2.18 acre post -1981 area. Change #4 This change proposes to add a 0.2 acre area of bank armoring on the southern end of the Seeley Lake Overflow Ditch, to protect the outflow pipe section of bank from eroding. This work was done to protect the inlet side of the pipe, and at the request of the ditch company. STAR - DRMS -TR -letter &maps - 021615. docx
