Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Except as provided in subdivision (c),
					 within 60 days after the cessation of a well stimulation treatment, the
					 operator shall publicly disclose all of the following information:
(1) Operator's name;
(2) API number assigned to the well by the
					 Division;
(3) Lease name and number
					 of the well;
(4) Location of the
					 well, submitted as a six-digit decimal degrees, non-projected, Latitude and
					 Longitude, in the Geographic Coordinate System (GCS) NAD83.
(5) County in which the well is
					 located;
(6) Date that the well
					 stimulation treatment occurred;
(7)
					 The measured and true vertical depth of the well;
(8) Formation name and vertical depth of the
					 top and bottom of the productive horizon where well stimulation treatment
					 occurred;
(9) The trade name,
					 supplier, concentration, and a brief description of the intended purpose of
					 each additive contained in the well stimulation fluids used;
(10) The total volume of base fluid used
					 during the well stimulation treatment;
(11) Identification of whether the base fluid
					 is water suitable for irrigation or domestic purposes, water not suitable for
					 irrigation or domestic purposes, or a fluid other than water;
(12) The source, volume, and specific
					 composition and disposition of all water associated with the well stimulation
					 treatment, including all of the following:
(A)
					 The source of the water used as a base fluid for the well stimulation
					 treatment, including any of the following:
(i)
					 The well or wells, if commingled, from which the water was produced or
					 extracted;
(ii) The water supplier,
					 if purchased from a supplier;
(iii)
					 The point of diversion of surface water;
(B) Composition of water used as base fluid,
					 including all of the following: total dissolved solids; metals listed in
					 California Code of Regulations, title 22, section
					 66261.24, subdivision (a)(2)(A);
					 benzene, toluene, ethyl benzene, and xylenes; major and minor cations
					 (including sodium, potassium, magnesium, and calcium); major and minor anions
					 (including nitrate, chloride, sulfate, alkalinity, and bromide); and trace
					 elements (including lithium, strontium, and boron);
(C) Specific disposition of water recovered
					 from the well following the well stimulation treatment, including method and
					 location of disposal and, if the recovered water is injected into an injection
					 well, identification of the operator, field, and project number of the
					 injection project;
(D) Composition
					 of water recovered from the well following the well stimulation treatment,
					 sampled after a calculated wellbore volume has been produced back but before
					 three calculated wellbore volumes have been produced back, and then sampled a
					 second time after 30 days of production after the first sample is taken, with
					 both samples taken prior to being placed in a storage tank or being aggregated
					 with fluid from other wells;
(E)
					 Composition of water recovered from the well following the well stimulation
					 treatment shall be determined by testing the samples taken under paragraph (D)
					 for all of the following: appropriate indicator compound(s) for the well
					 stimulation treatment fluid; total dissolved solids; metals listed in
					 California Code of Regulations, title 22, section
					 66261.24, subdivision (a)(2)(A);
					 benzene, toluene, ethyl benzene, and xylenes; major and minor cations
					 (including sodium, potassium, magnesium, and calcium); major and minor anions
					 (including nitrate, chloride, sulfate, alkalinity, and bromide); and trace
					 elements (including lithium, strontium, and boron); radium-226, gross
					 alpha-beta, radon 222, fluoride, iron (redox), manganese (redox), H2S (redox),
					 nitrate+nitrite (redox), strontium, thallium, mercury, and methane;
(F) All testing results shall have a cover
					 page briefly describing when and where sampling was done and the results of the
					 testing;
(G) Sampling and testing
					 conducted under subdivision (a)(12) is separate from and in addition to any
					 sampling or testing that may be required to make hazardous waste determinations
					 under the requirements of the Department of Toxic Substances
					 Control;
(13)
					 Identification of any reuse of treated or untreated water for well stimulation
					 treatments and well stimulation treatment-related activities;
(14) The specific composition and disposition
					 of all well stimulation treatment fluids, including waste fluids, other than
					 water;
(15) Any radiological
					 components or tracers injected into the well as part of the well stimulation
					 treatment, a description of the recovery method, if any, for those components
					 or tracers, the recovery rate, and specific disposal information for recovered
					 components or tracers;
(16) The
					 radioactivity of the recovered well stimulation fluids, and a brief description
					 of the equipment and method used to determine the radioactivity;
(17) For each stage of the well stimulation
					 treatment, the measured and true vertical depth of the location of the portion
					 of the well subject to the well stimulation treatment and the extent of the
					 fracturing or other modification, if any, surrounding the well induced by the
					 treatment;
(18) The estimated
					 volume of well stimulation treatment fluid that has been recovered;
					 and
(19) A complete list of the
					 names, Chemical Abstract Service numbers, and maximum concentration, in percent
					 by mass, of each and every chemical constituent of the well stimulation
					 treatment fluids used. If a Chemical Abstract Service number does not exist for
					 a chemical constituent, the operator may provide another unique identifier, if
					 available.
