N.D. Admin. Code 43-02-02.2-43

Current through Supplement No. 392, April, 2024
Section 43-02-02.2-43 - Production area operational monitoring requirements

The permit's monitoring plan must describe the procedures for monitoring the quantity and quality of mining solution and ground water in the production area and must include provisions for:

1. The analysis of the physical and chemical characteristics of the injected fluid, with sufficient frequency, and at least monthly, to yield representative data. Manifold monitoring may be used in cases of facilities consisting of more than one injection well operating with a common manifold. Separate monitoring systems for each well are not required provided the operator demonstrates to the department that manifold monitoring is comparable to individual well monitoring;
2. Monitoring injection pressure and either flow rate or volume every two weeks, or metering and recording daily injected and produced fluid volumes;
3. Monitoring the fluid level in the injection zone every two weeks;
4. Monitoring wells in the injection zone shall be sampled every two weeks for chloride, total dissolved solids, alkalinity, conductivity, and any additional parameters requested by the department;
5. Monitoring ground water quality, including the control parameters, and fluid levels in monitoring wells completed above and below the production zone a minimum of every two weeks; and
6. A minimum of quarterly monitoring of department-specified wells within one-quarter mile [.40 kilometer] of the production site to detect migration of recovery fluids from the production zone.
