Butter Creek CGWA: Distribution of Sustainable Annual Yield
(1)
The method for distributing the sustainable annual yield from the basalt groundwater reservoir within each subarea in the Butter Creek Critical Groundwater Area is as follows:(a)
Except as provided in sections (5) of this rule, a water user who intends to pump water during any year shall make a request to the Department in Salem by July 1st of the preceding year on forms provided by the Department.(b)
The distribution of groundwater shall be based on the priority dates of the water rights within the individual subarea.(c)
In determining the amount of groundwater each water user is allocated to pump during the next calendar year or irrigation season, the Department may consider:(A)
Request for allocations received;(B)
The sustainable annual yield;(C)
The limits of the groundwater rights;(D)
The relative dates of priority;(E)
Historical usage;(F)
Whether or not a water user is physically capable of pumping and putting to a beneficial use the quantity requested; and(G)
Any other factors deemed appropriate by the Department.(d)
The Department shall notify, by certified mail with return receipt requested, each water user by August 1st of the amount of groundwater allocated under these rules to each water user for the next calendar year or irrigation season.(2)
If pumpage for a particular year exceeds the sustainable annual yield for a subarea, the total subarea allocation for the second year after that occurrence shall be reduced by that volume.(3)
If any water user requests more water than has been historically used, the Department may allocate less water than requested if, upon investigation, it appears unlikely the user will pump the volume requested.(4)
If any water user requests less water than has been historically used, the Department may allocate more water than requested if, upon investigation, it appears likely that the user will pump more than the volume requested.(5)
The method of requesting and distributing water in section (1) of this rule may not apply if a voluntary agreement among groundwater users in any subarea is reached. The Director may approve the agreement if it is consistent with ORS 537.730 (Designation of critical ground water area) to 537.740 (Filing rules designating critical ground water area) and the requirements of these rules (division 507). The Department shall be a party to any agreement reached.(6)
Any agreement approved by the Director may be terminated by the lapse of time as provided in the agreement, by consent of the parties to the agreement or by the Director if the Director finds, after investigation and a public hearing upon adequate notice, that:(a)
The agreement is not being substantially complied with by the parties thereto;(b)
Changed conditions have made the continuance of the agreement a detriment to the public welfare, safety and health or contrary in any particular to the intent, purposes and requirements of ORS 537.505 (Short title) to 537.795 (ORS 537.505 to 537.795 supplementary) or OAR chapter 690, division 507; or(c)
That the agreement is ineffective in achieving reasonably stable water levels.
