# §3174.12. Measurement tickets.

- (a) **Tank gauging.** After oil is measured by tank gauging under §§ [3174.5](/cfr/43/3174.5.md) and [3174.6](/cfr/43/3174.6.md) 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)](/cfr/43/3174.5.md?p=c));
  - (6) Total gross standard volume removed from the tank following API 11.1 (incorporated by reference, see [§ 3174.3](/cfr/43/3174.3.md));
  - (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](/cfr/43/3174.3.md));
  - (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](/cfr/43/3174.10.md), 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.
