Section 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 );(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;(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.
