Section 216 - GLOBAL POSITIONING SYSTEMS
Current through Register Vol. 47, No. 17, September 10, 2024
Global Positioning Systems ("GPS") may be used to locate facilities used in Oil and Gas Operations provided they meet the following minimum standards:
a. GPS instruments are differential grade.
b. GPS instruments are capable of 1-meter horizontal positional accuracy after differential correction.
c. The Operator will report an accuracy value (in meters) or position dilution of precision ("PDOP") value with all submitted GPS data. Accuracies of 1.0 meter or less and PDOP readings of 6.0 or less are acceptable.
d. Elevation mask (lowest acceptable height above the horizon) will be no less than 15 degrees.
e. Latitude and longitude coordinates will be provided in decimal degrees with an accuracy and precision of 5 decimals of a degree using the North American Datum ("NAD") of 1983 (e.g., latitude 37.12345 N, longitude 104.45632 W).
f. Raw and corrected data files will be held for a period of 3 years.
g. Measurements will be made by a trained GPS operator familiar with the theory of GPS, the use of GPS instrumentation, and typical constraints encountered during field activities.
