Section XIX-539 - Monitoring Requirements for Commercial Class II Injection Wells

A. Except during approved workover operations, a positive pressure of no less than 100 psi shall be maintained on the well annulus at all times. An injection volume recorder (tamper proof meter) must be installed and properly maintained on the injection line of each disposal well system. Injected volumes must be recorded monthly and the readings reported monthly on the Commercial Class II Daily Monitoring Log (Form UIC-21, or latest revision) and annually on the annual injection well report.

B. Except during approved workover operations, wells shall be equipped with pressure gauges located on the wellhead, and situated so as to monitor the pressure of the injection stream and the pressure of the annular space between the casing and the injection string.

C. The pressure gauges shall have half-inch fittings, be scaled in increments of not more than 10 psi, and be maintained in good working order at all times.

D. A daily pressure monitoring log shall be maintained by the operator of the facility and shall contain, as a minimum, the following information:

1. the date;

2. the operator's name and address;

3. the well name, number and serial number;

4. the monitored injection pressure;

5. the monitored annulus pressure;

6. whether or not the well was injecting at the time the pressures were recorded; and

7. the name or initials of the person logging the information.

E. The pressure gauges shall be read and pressures recorded in the daily log.

F. The daily log information shall be recorded on the appropriate form (UIC - 21, or latest revision) and submitted to the Office of Conservation. The original hard copy or original electronic copy Form UIC - 21 monthly reports(s) for all permitted commercial Class II injection wells must be received by the Office of Conservation on or before the 15^th day of the following month. If delivered on the 15th day, the subject report(s) must be received by the Office of Conservation before the close of business, i.e., no later than 4:30 p.m. In the event that the 15th day of any given month falls on a Saturday, Sunday, or state holiday, the reporting deadline shall be the following regularly scheduled business day, before the close of business.

G. Any discrepancies in the monitored pressures, which would indicate a lack of mechanical integrity and constitute noncompliance with applicable Sections of this Chapter, shall be reported orally to the Office of Conservation within 24 hours.

H. The commissioner may require, on a case-by-case basis, the installation of a 24-hour chart recorder to monitor injection pressures, injection rates, annulus pressure and injected volumes.
