California Code of Regulations › Title 23 - Waters › Division 3 - State Water Resources Control Board and Regional Water Quality Control Boards › Chapter 16 - Underground Tank Regulations › Article 4 - Existing Underground Storage Tank Monitoring Requirements › Section 2646.1 - Statistical Inventory Reconciliation

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
				  When approved by the local agency, statistical inventory reconciliation may be
				  used as part of a non-visual monitoring program, set forth in section
				  2643(b)(2), for
				  existing underground storage tanks which contain motor vehicle fuel.
(b) Each underground storage tank shall be
				  individually monitored using a method that incorporates the following
				  procedures:
(1) Separate daily measurements
				  shall be taken and recorded for both the motor vehicle fuel and any water
				  layer. For the purpose of this section, "daily" means at least every day that
				  motor vehicle fuel is added to or withdrawn from the tank, but no less than
				  five days per week. The number of days may be reduced by the number of public
				  holidays that occur during the week if there is no input to or withdrawal from
				  the tank on the holiday. Local agencies may reduce the frequency of monitoring
				  to not less than once every three days at facilities that are not staffed on a
				  regular basis provided that the monitoring is performed every day the facility
				  is staffed. The number of days may be reduced only if consistent with the
				  independent third party certification required by section
				  2643(f).
				  Measurements shall be:
(A) Taken when no
				  substance is being added to or withdrawn from the tank;
(B) Performed by the owner, operator, or
				  other designated persons who have had appropriate training;
(C) Based on the average of two readings if
				  dipstick or tape measurements are used;
(D) Determined by equipment capable of
				  measuring the level of the product over the full range of the tank's height to
				  the nearest one-eighth of an inch. If a dipstick is used to determine the
				  product level, a substance capable of rendering the readings legible shall be
				  applied to the dipstick before use, if necessary to obtain accurate
				  readings;
(E) Determined by
				  equipment capable of measuring, to the nearest one-eighth of an inch, water
				  present in the bottom of the tank. If a dipstick is used, water-finding paste
				  shall be applied to the dipstick. If the tank is not level, and the
				  measurements are taken manually, the measurements shall be taken at the lowest
				  end of the tank;
(F) Measured at
				  the center of the longitudinal axis of the tank if access is available or
				  measured at the lowest end of the tank with a calibration measurement at both
				  ends, if possible, to determine if any tank tilt exists, and, if so, its
				  magnitude; and
(G) Converted to
				  volume measurements based on a calibration chart for the tank. This chart
				  shall, where feasible, take into account the actual tilt of the
				  tank.

				  evaluation procedures are in Appendix IV;
(3) The existing ground water level or the
				  highest anticipated ground water level, including intermittent perched ground
				  water, is less than 20 feet from the ground surface. These ground water levels
				  shall be determined according to the requirements of section
				  2649(c);
(4) The hydraulic conductivity of the soil(s)
				  between the underground storage tank and the monitoring wells or devices is at
				  least 0.01 centimeters per second (e.g., the soil consists of gravels, coarse
				  to medium sands, or other permeable materials);
(5) The ground water proposed for monitoring
				  has no present beneficial uses (e.g., domestic, municipal, industrial, or
				  agricultural supply) or is not hydraulically connected to ground or surface
				  water which has actual beneficial uses; and

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
				  Tank lining may be used to satisfy part of the upgrade requirements of section
				  2662 or to repair a tank pursuant
				  to section
				  2661. However, a tank that has
				  been repaired using the interior lining method may not be repaired a second
				  time with the interior lining method. The evaluations described in subdivisions
				  (b) and (c) of this section shall be completed before the lining of a primary
				  container may be authorized by the local agency. The local agency shall deny
				  the proposed lining if the owner fails to demonstrate that the lined primary
				  container will provide continued containment based on the evaluations described
				  in subdivisions (b) and (c).
(b)
				  Appropriate tests shall be conducted by a special inspector who shall certify
				  that the shell will provide structural support if the tank is lined. A copy of
				  this certification shall be submitted by the owner to the local agency through
				  the California Environmental Reporting System or a local reporting portal. The
				  special inspector shall make this certification by entering and inspecting the
				  entire interior surface of the tank and shall base this certification upon of
				  the following sets of procedures and criteria:
(1) If a tank is made of non-corrodible
				  material, the following shall be performed:
(A) The tank shall be cleaned so that no
				  residue remains on the tank wall surface;
(B) The special inspector shall take interior
				  diameter measurements and, if the cross-section of the tank has compressed more
				  than one percent of the original diameter, the tank shall neither be certified
				  nor returned to service unless the tank is excavated and repaired to correct
				  the compression;
(C) The special
				  inspector shall conduct an interior inspection to identify any area where
				  compression or tension cracking is occurring and shall determine whether
				  additional fiberglass reinforcing is required for certification before the tank
				  may be lined; and
(D) If the
				  special inspector does not certify the tank as suitable for lining because it
				  failed a test conducted in accordance with subparagraphs (A) through (C) of
				  this paragraph, the tank shall be closed in accordance with Article
				  7.
