Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
					 The appropriate Division district deputy shall be notified of any anticipated
					 changes in an underground injection project resulting in inconsistency with the
					 current conditions of approval, such as: expansion of the project, change of
					 injection interval, or increase in maximum allowable surface injection
					 pressure. Such changes shall not be carried out without prior written approval
					 of the Division in accordance with Section
					 1724.6.
(b) In addition to the notice of intention
					 that may be required under Public Resources Code section
					 3203,
					 any addition of an injection well to an underground injection project,
					 including the conversion of a well without alteration of casing, requires the
					 prior written approval of the Division in accordance with Section
					 1724.6. The operator shall notify
					 the Division and conduct testing as required under Section
					 1724.10.1 if the packer or tubing
					 in an injection well is set, reset, moved, or changed.
(c) An injection report on a current Division
					 form or in a digital format acceptable to the Division shall be filed with the
					 Division on or before the last day of each month, for the preceding
					 month.
(d) A representative
					 chemical analysis of the liquid being injected, as specified in Section
					 1724.7.2, shall be made and filed
					 with the Division whenever the source of injection liquid is changed, or as
					 requested by the Division. For the purposes of this subdivision, the source of
					 injection is changed if a contributing source is added to or removed from the
					 injection liquid, or if there is a significant change to the relative
					 contribution of individual sources such that the last chemical analysis is not
					 representative of the liquid being injected.
(e) For each underground injection project
					 that includes an injection well with open perforations located within 500
					 linear feet of the screen or perforations of a water supply well, the operator
					 shall provide to the Division in digital format on a yearly basis all of the
					 information listed in subdivisions (e)(1) through (e)(4). On a project-specific
					 or well-specific basis, the Division may specify a distance greater than 500
					 feet as the distance that triggers the requirements of this subdivision if, in
					 the Division's judgment, geological conditions or the relative location of any
					 water supply well warrants the additional data collection listed in
					 subdivisions (e)(1) through (4). The applicability of this subdivision shall be
					 based on a diligent search by the operator, including consultation of public
					 records, and is not triggered by water source wells. When applicable, the
					 following information shall be provided:
(1)
					 A water treatment process flow diagram depicting all physical and chemical
					 treatment processes applied to the injection fluid, from its source to the
					 injection well;
(2) The safety data
					 sheet for each chemical additive emplaced in injection wells within the
					 underground injection project, and for each chemical added to the fluid to be
					 injected from the time the fluid is first obtained to the time it is
					 injected;
(3) The project-aggregate
					 volume or weight of each additive reported under subdivision (e)(2);
					 and
(4) A brief description of the
					 intended purpose of each additive reported under subdivision
					 (e)(2).
