WAC 173-517-160

Accounting for use under the reserves.

(1) Ecology shall maintain a record of all appropriations from the reserves.
(2) For an appropriation under a permit, ecology will account for water use under the reserve based on authorized quantities under water right permits or certificates, and metering data.
(3) For permit-exempt groundwater appropriations from reserves other than Chimacum subbasin, ecology will deduct a standard amount of 250 gpd for each single domestic use. For a permit-exempt agricultural use, ecology will deduct 5,000 gpd for the Big Quilcene and Salmon Creek subbasins and 3,000 gpd for the Snow Creek subbasin. The amounts deducted from the reserves may be adjusted periodically by ecology, to reflect actual use during low flow conditions based on metering data or other measurements.
(4) For permit-exempt groundwater appropriations from the Chimacum reserve, ecology will deduct a standard amount of 13 gpd for each single domestic use.
(5) If a water user permanently ceases use of water, ecology may credit the water to the appropriate reserve, upon demonstration, through written certification, that the well or surface water diversion has been decommissioned.
(6) Ecology shall notify the county (or counties) with jurisdiction, and publish a public notice, when it determines that fifty percent, seventy-five percent, and one hundred percent, respectively, of a reserve is appropriated.
(7) If a new appropriation, located in a subbasin with a reserve, is fully offset through implementation of an approved mitigation plan as described in WAC 173-517-030(12), then ecology will not deduct the amount of new water use from the reserve.
