Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) For
				  purposes of this article, the terms used are defined in this section.
(1) "Accuracy" means the measured volume
				  relative to the actual volume, expressed as a percent. The percent shall be
				  calculated as 100 x (measured value - actual value) / actual value, where
				  "measured value" is the value indicated by the device or determined through
				  calculations using a measured value by the device, such as flow rate, combined
				  with a duration of flow, and "actual value" is the value as determined through
				  laboratory, design or field testing protocols using best professional
				  practices.
(2) "Agricultural water
				  supplier," as defined in Water Code §
											10608.12(a),
				  means a water supplier, either publicly or privately owned, providing water to
				  10,000 or more irrigated acres, excluding acres that receive only recycled
				  water. "Agricultural water supplier" includes a supplier or contractor for
				  water, regardless of the basis of right, which distributes or sells water for
				  ultimate resale to customers. "Agricultural water supplier" does not include
				  the Department.
(3) "Approved by an
				  engineer" means a California-registered Professional Engineer has reviewed,
				  signed and stamped the plans, design, testing, inspection, and/or documentation
				  report for a measurement device as described in this article.
(4) "Best professional practices" means
				  practices attaining to and maintaining accuracy of measurement and reporting
				  devices and methods described in this article, such as operation and
				  maintenance procedures and practices recommended by measurement device
				  manufacturers, designers, and industry professionals.
(5) "Customer" means the purchaser of water
				  from an agricultural water supplier who has a contractual arrangement with the
				  agricultural water supplier for the service of conveying water to the customer
				  delivery point.
(6) "Delivery
				  point" means the location at which the agricultural water supplier transfers
				  control of delivered water to a customer or group of customers. In most
				  instances, the transfer of control occurs at the farm-gate, which is therefore,
				  a delivery point.
(7) "Existing
				  measurement device," means a measurement device that was installed in the field
				  prior to the effective date of this article.
(8) "Farm-gate," as defined in Water Code
				  §
											531(f),
				  means the point at which water is delivered from the agricultural water
				  supplier's distribution system to each of its customers.
(9) "Irrigated acres," for purposes of
				  applicability of this article, is calculated as the average of the previous
				  five-year acreage within the agricultural water supplier's service area that
				  has received irrigation water from the agricultural water supplier.
(10) "Manufactured device" means a device
				  that is manufactured by a commercial enterprise, often under exclusive legal
				  rights of the manufacturer, for direct off-the-shelf purchase and installation.
				  Such devices are capable of directly measuring flow rate, velocity, or
				  accumulating the volume of water delivered, without the need for additional
				  components that are built on-site or in-house.
(11) "Measurement device" means a device by
				  which an agricultural water supplier determines the numeric value of flow rate,
				  velocity or volume of the water passing a designated delivery point. A
				  measurement device may be a manufactured device, on-site built device or
				  in-house built device.
(12) "New or
				  replacement measurement device" means a measurement device installed after the
				  effective date of this article.
(13) "Recycled water" is defined in
				  subdivision (n) of §
											13050 of the
				  Water Code as water that, as a result of treatment of waste, is suitable for a
				  direct beneficial use or a controlled use that would not otherwise occur, and
				  is therefore considered a valuable resource.
(14) "Type of device" means a measurement
				  device that is manufactured or built to perform similar functions. For example,
				  rectangular, v-notch, and broad crested weirs are one type of device.
				  Similarly, all submerged orifice gates are considered one type of
				  device.
