§ 3174.12 Measurement tickets.

(a) Tank gauging. After oil is measured by tank gauging under §§ 3174.5 and 3174.6 of this subpart, the operator, purchaser, or transporter, as appropriate, must complete a uniquely numbered measurement ticket, in either paper or electronic format, with the following information: (1) Lease, unit PA, or CA number; (2) Unique tank number and nominal tank capacity; (3) Opening and closing dates and times; (4) Opening and closing gauges and observed temperatures in °F; (5) Observed volume for opening and closing gauge, using tank specific calibration charts (see § 3174.5(c)); (6) Total gross standard volume removed from the tank following API 11.1 (incorporated by reference, see § 3174.3); (7) Observed API oil gravity and temperature in °F; (8) API oil gravity at 60 °F, following API 11.1 (incorporated by reference, see § 3174.3); (9) S&W content percent; (10) Unique number of each seal removed and installed; (11) Name of the individual performing the tank gauging; and (12) Name of the operator. (b) LACT system and CMS. (1) At the beginning of every month, and, unless the operator is using a flow computer under § 3174.10, before conducting proving operations on a LACT system, the operator, purchaser, or transporter, as appropriate, must complete a uniquely numbered measurement ticket, in either paper or electronic format, with the following information: (i) Lease, unit PA, or CA number; (ii) Unique meter ID number; (iii) Opening and closing dates; (iv) Opening and closing totalizer readings of the indicated volume; (v) Meter factor, indicating if it is a composite meter factor; (vi) Total gross standard volume removed through the LACT system or CMS; (vii) API oil gravity. For API oil gravity determined from a composite sample, the observed API oil gravity and temperature must be indicated in °F and the API oil gravity must be indicated at 60 °F. For API oil gravity determined from average density (CMS only), the average uncorrected density must be determined by the CMS; (viii) The average temperature in °F; (ix) The average flowing pressure in psig; (x) S&W content percent; (xi) Unique number of each seal removed and installed; (xii) Name of the purchaser's representative; and (xiii) Name of the operator. (2) Any accumulators used in the determination of average pressure, average temperature, and average density must be reset to zero whenever a new measurement ticket is opened.
