  1. (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.
  2. (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
        1. (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.
