(C) When the GIE device has been inactive GIE for less than five consecutive years and is being removed from the GIE owner's inventory (e.g., to be disposed of, sold, transferred to a new GIE owner).

(2) Shall be considered "transferred while in use" in section 95354.1(a) when the GIE device is removed from a GIE owner's inventory without being taken out of active service (e.g., transferred to a new GIE owner while remaining in place and continuing operation).

(d) Within one year of a GIE device meeting any of the specifications in sections 95354(c)(1)(A) through 95354(c)(1)(C), covered insulating gas must be removed and accounted for. The amount of covered insulating gas transferred out of the GIE device (pounds) must be recorded by the GIE owner or by the manufacturer, contractor, or vendor that recovers the gas. The GIE owner is responsible for ensuring the gas is accounted for consistent with the methodologies specified in section 95354(d)(1) or (2).

(1) Weigh the gas container being used to receive the covered insulating gas from the device prior to, and after, recovery of the covered insulating gas from the GIE device following the requirements of section 95354(e), and subtract the first value (prior-to-transfer gas container weight) from the second value (after-transfer gas container weight).

(2) Use a mass flow meter as described in section 95354(b)(2).

(g) GIE owners must weigh covered gas containers at the points in time set forth in sections 95354(g)(1)(A)-(B) and 95354(g)(2). Each time a container is weighed, record the date, the amount of covered insulating gas in the container (pounds), and the reason why the container was weighed (end of calendar year weighing, added to inventory, removed from inventory).

(1) For each covered gas container owned by or stored on the property of the GIE owner, all of which make up the GIE owner's gas container inventory, weigh the gas container at the following times:
(A) The end of the calendar year. To determine this value, containers must be weighed on or between December 1 of the data year and January 15 of the next data year. The container may only be weighed in January of the next data year if it was not used between December 31 of the data year and the date the container is weighed.

(B) Whenever the covered gas container is added to, or removed from, the GIE owner's gas container inventory.

(2) For covered gas containers that are neither owned by nor stored on the property of the GIE owner, weigh the gas container both immediately before and immediately after use at any of the GIE owner's facilities for the purpose of adding or removing insulating gas to or from GIE, a gas cart, or another container following the requirements of section 95354(e).

(3) To determine the amount of covered insulating gas in the gas container, weigh the gas container (along with its contents), and subtract the tare weight of the container.

(h) GIE owners must establish and maintain a current and complete inventory of all covered gas containers and gas carts that contain covered insulating gas. The inventory must include the following information for each covered gas container and gas cart:

(1) For gas containers, whether it is required to be weighed pursuant to section 95354(g)(1) or 95354(g)(2), and for gas carts, whether the amount of gas within the cart is determined pursuant to section 95354(j)(2)-(3) or 95354(j)(4).

(2) A unique identification number.

(3) The name and GWP of each covered insulating gas used.

(4) For gas containers, information required to be recorded pursuant to section 95354(g), and for gas carts, information required to be recorded pursuant to section 95354(j).

(5) The amount of covered insulating gas in the container or gas cart (pounds) at the beginning of the data year. This value must be identical to the value reported for the end of the prior data year pursuant to section 95354(g)(1)(A) or 95354(j)(2).

(i) Transfers of covered insulating gas. Each time covered insulating gas is transferred into or out of a GIE device, GIE owners must record:

(1) The manufacturer serial number pursuant to section 95354(a)(3);

(2) The gas container's unique identification number;

(3) Whether the covered insulating gas was transferred into or out of the GIE device;

(4) The date of the transfer; and

(5) The type of covered insulating gas.

(j) Gas Carts. GIE owners must do the following for all gas carts owned by or stored on the property of the GIE owner that contain covered insulating gas:

(1) By January 1, 2022, the GIE owner must determine whether they will account for covered insulating gas in each gas cart using the "container method" following the requirements of section 95354(j)(2)(A), the "scale method" following the requirements of section 95354(j)(2)(B), or the "mass flow meter method" following the requirements of section 95354(j)(2)(C) and must, for each gas cart, use the method selected for all subsequent measurements of the amount of covered insulating gas in that gas cart pursuant to section 95354(j)(2)-(3). Whenever a GIE owner acquires a gas cart after December 31, 2021, they must select the methodology they will use at the time the gas cart is acquired.

(2) For each gas cart owned by or stored on the property of the GIE owner on December 31 of the data year, the amount of covered insulating gas within the gas cart at the end of the calendar year must be determined during the timeframe established in section 95354(g)(1)(A) using the methodology selected pursuant to section 95354(j)(1):
(A) Container method. Transfer insulating gas from the gas cart to a covered gas container(s) until the gas cart reaches the pressure specified by the GIE owner in section 95354(j)(2)(D). Weigh the gas container(s) before and after the transfer and determine the weight of the covered insulating gas in the gas cart by subtracting the first recorded value from the second;

(B) Scale method. Determine the amount of gas stored in the gas cart by weighing the gas cart itself, and subtracting the tare weight, following the procedures in section 95354(g)(3); or

(C) Mass flow meter method. Connect a mass flow meter between the gas cart and a container or another gas cart and recover gas until the pressure specified by the GIE owner in section 95354(j)(2)(D) is reached, then determine the amount of gas transferred from the mass reading on the mass flow meter.

(D) GIE owners using the container method or mass flow meter method must, for each gas cart, specify by January 1, 2022 or the date the gas cart is acquired, the pressure at which the cart is empty according to manufacturer specifications, and bring the cart to that pressure every time they account for covered insulating gas in that gas cart.

(E) GIE owners must not include gas accounted for pursuant to section 95354(j)(2) in any measurements made pursuant to section 95354(g)(1) or (2).

(3) Whenever a gas cart is added to, or removed from, the GIE owner's inventory, the amount of covered insulating gas within the gas cart must be determined using the method selected pursuant to section 95354(j)(1).

(4) Each time a gas cart that is neither owned by nor stored on the property of the GIE owner is brought onto or removed from the property of the GIE owner, the GIE owner must:
(A) Follow the procedures of section 95354(j)(2)(A);

(B) Follow the procedures of section 95354(j)(2)(B); or

(C) Follow the procedures of section 95354(j)(2)(C).

(k) GIE owners must establish and adhere to written procedures to track all covered gas containers included in the inventory compiled pursuant to section 95354(h). The GIE owner must review the procedures annually and revise them as needed to ensure the information is current and the requirements of sections 95354(e)-(j) are met.

(l) Calibration. GIE owners must:

(1) Prior to a scale's initial use to measure quantities reported under this subarticle, the scale must be calibrated according to the calibration procedures specified by the scale manufacturer. If a scale manufacturer has not specified calibration procedures, use NIST-traceable standards and a published calibration method identified as appropriate for that scale by either the International Society of Weighing and Measurement or the National Conference on Weights and Measures.

(2) Recalibrate scales used to measure quantities reported under this subarticle every three years, or at the minimum frequency specified by the manufacturer, whichever is more frequent. If a scale manufacturer has not specified calibration procedures, use NIST-traceable standards and a published calibration method identified as appropriate for that scale by either the International Society of Weighing and Measurement or the National Conference on Weights and Measures.

(3) Prior to a mass flow meter's initial use to measure quantities reported under this subarticle, the flow meter must be calibrated according to the calibration procedures specified by the manufacturer. If a mass flow meter manufacturer has not specified calibration procedures, use NIST-traceable standards and an appropriate flow meter calibration method published by a consensus-based standards organization.

(4) Recalibrate mass flow meters, pressure gauges, and temperature gauges used to measure quantities reported under this subarticle at the minimum frequency specified by the manufacturer.

(5) Establish and maintain a log of all measurements and calibrations required by sections 95354 (l)(1)-(4), including a description of all methods used to calibrate the scale or flow meter, providing sufficient detail to establish that the method complies with the requirements of sections 95354 (l)(1)-(4).

(m) Gas Blends. Whenever covered insulating gas that is a constituent of a gas blend must be quantified, use the following equation to calculate the amount of covered insulating gas to be reported (pounds) and record the values of the inputs used:

Covered Insulating Gas = (Insulating Gas) * (Mass Share)

Where

"Covered Insulating Gas" is the amount of covered insulating gas required to be reported (pounds);

"Insulating Gas" is the total amount of insulating gas (pounds) in the gas blend of which the covered insulating gas is a constituent member; and

"Mass Share" is the ratio of the mass of covered insulating gas relative to the total amount of insulating gas expressed as a decimal value.
