  ( Part 2 enacted by Stats. 1943, Ch. 368. )

ARTICLE 3. Monitoring and Reporting [1840 - 1841.5]
  ( Article 3 added by Stats. 2015, Ch. 27, Sec. 15. )

1840.
  

(a) (1) Except as provided in subdivision (b), a person who, on or after January 1, 2016, diverts 10 acre-feet of water per year or more under a permit or license shall install and maintain a device or employ a method capable of measuring the rate of direct diversion, rate of collection to storage, and rate of withdrawal or release from storage. The measurements shall be made using the best available technologies and best professional practices, as defined in Section 5100, using a device or methods satisfactory to the board, as follows:

(A) A device shall be capable of continuous monitoring of the rate and quantity of water diverted and shall be properly maintained. The permittee or licensee shall provide the board with evidence that the device has been installed with the first report submitted after installation of the device. The permittee or licensee shall provide the board with evidence demonstrating that the device is functioning properly as part of the reports submitted at five-year intervals after the report documenting installation of the device, or upon request of the board.

(B) In developing regulations pursuant to Section 1841, the board shall consider devices and methods that provide accurate measurement of the total amount diverted and the rate of diversion. The board shall consider devices and methods that provide accurate measurements within an acceptable range of error, including the following:

(i) Electricity records dedicated to a pump and recent pump test.

(ii) Staff gage calibrated with an acceptable streamflow rating curve.

(iii) Staff gage calibrated for a flume or weir.

(iv) Staff gage calibrated with an acceptable storage capacity curve.

(v) Pressure transducer and acceptable storage capacity curve.

(2) The permittee or licensee shall maintain a record of all diversion monitoring that includes the date, time, and diversion rate at time intervals of one hour or less, and the total amount of water diverted. These records shall be included with reports submitted under the permit or license, as required under subdivision (c), or upon request of the board.

(b) (1) The board may modify the requirements of subdivision (a) upon finding either of the following:

(A) That strict compliance is infeasible, is unreasonably expensive, would unreasonably affect public trust uses, or would result in the waste or unreasonable use of water.

(B) That the need for monitoring and reporting is adequately addressed by other conditions of the permit or license.

(2) The board may increase the 10-acre-foot reporting threshold of subdivision (a) in a watershed or subwatershed, after considering the diversion reporting threshold in relation to quantity of water within the watershed or subwatershed. The board may increase the 10-acre-foot reporting threshold to 25 acre-feet or above if it finds that the benefits of the additional information within the watershed or subwatershed are substantially outweighed by the cost of installing measuring devices or employing methods for measurement for diversions at the 10-acre-foot threshold.

(c) At least annually, a person who diverts water under a registration, permit, or license shall report to the board the following information:

(1) The quantity of water diverted by month.

(2) The maximum rate of diversion by months in the preceding calendar year.

(3) The information required by subdivision (a), if applicable.

(4) The amount of water used, if any, for cannabis cultivation.

(d) Compliance with the applicable requirements of this section is a condition of every registration, permit, or license.

(Amended by Stats. 2016, Ch. 32, Sec. 98. (SB 837) Effective June 27, 2016.)

1841.
  

(a) The board may adopt regulations requiring measurement and reporting of water diversion and use by either of the following:

(1) Persons authorized to appropriate water under a permit, license, registration for small domestic, small irrigation, or livestock stockpond use, or certification for livestock stockpond use.

(2) Persons required to comply with measurement and reporting regulations pursuant to subparagraph (B) of paragraph (1) of subdivision (e) of Section 5103.

(b) The initial regulations that the board adopts pursuant to this section shall be adopted as emergency regulations in accordance with Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code. The adoption of the initial regulations is an emergency and shall be considered by the Office of Administrative Law as necessary for the immediate preservation of the public peace, health, safety, and general welfare. Notwithstanding Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code, any emergency regulations adopted under this section shall remain in effect until revised by the board.

(c) The adoption of the initial regulations pursuant to this article is exempt from Division 13 (commencing with Section 21000) of the Public Resources Code.

(Added by Stats. 2015, Ch. 27, Sec. 15. (SB 88) Effective June 24, 2015.)

1841.5.
  

(a) For the purposes of a device installed pursuant to Section 1840 or 1841 or a method of measurement proposed and adopted pursuant to Section 934 or 935 of Title 23 of the California Code of Regulations, any diverter who has completed an instructional course regarding the devices or measurement method included in the course administered by the University of California Cooperative Extension, including passage of a proficiency test before the completion of the course, shall be considered a qualified individual when installing and maintaining devices or implementing methods of measurement that were taught in the course for the diverter’s diversion. The proficiency test shall seek to certify that the diverter has a satisfactory understanding of the principles of measurement and the use of a measurement method included in the course or the installation of a device. The University of California Cooperative Extension and the board shall develop the curriculum of the course and the proficiency test. The University of California Cooperative Extension and the board shall ensure the course curriculum and the proficiency test do not conflict with any state licensing acts.

(b) For purposes of this section, “diverter” means an individual authorized to divert water under a valid water right, a lessee of property that is subject to a water right who is acting as a representative of the water right holder, or a bona fide employee of the water right holder or lessee.

(c) This section shall remain in effect only until January 1, 2023, and as of that date is repealed, unless a later enacted statute that is enacted before January 1, 2023, deletes or extends that date.

(Added by Stats. 2017, Ch. 471, Sec. 1. (AB 589) Effective January 1, 2018. Repealed as of January 1, 2023, by its own provisions.)
