(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. (1) Lease, unit PA, or CA number;
2. (2) Unique tank number and nominal tank capacity;
3. (3) Opening and closing dates and times;
4. (4) Opening and closing gauges and observed temperatures in °F;
5. (5) Observed volume for opening and closing gauge, using tank specific calibration charts (see § 3174.5(c));
6. (6) Total gross standard volume removed from the tank following API 11.1 (incorporated by reference, see § 3174.3);
7. (7) Observed API oil gravity and temperature in °F;
8. (8) API oil gravity at 60 °F, following API 11.1 (incorporated by reference, see § 3174.3);
9. (9) S&W content percent;
10. (10) Unique number of each seal removed and installed;
11. (11) Name of the individual performing the tank gauging; and
12. (12) Name of the operator.

(b) LACT system and CMS.

1. (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:

   1. (i) Lease, unit PA, or CA number;
   2. (ii) Unique meter ID number;
   3. (iii) Opening and closing dates;
   4. (iv) Opening and closing totalizer readings of the indicated volume;
   5. (v) Meter factor, indicating if it is a composite meter factor;
   6. (vi) Total gross standard volume removed through the LACT system or CMS;
   7. (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;
   8. (viii) The average temperature in °F;
   9. (ix) The average flowing pressure in psig;
   10. (x) S&W content percent;
   11. (xi) Unique number of each seal removed and installed;
   12. (xii) Name of the purchaser's representative; and
   13. (xiii) Name of the operator.
2. (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.
