Section 74:55:01:46 - Production area operational monitoring requirements

The monitoring plan included in the permit shall describe the procedures for operational monitoring of the quantity and quality of mining solution and ground water in the production area and shall, at a minimum, 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;

(2) Monitoring injection pressure and either flow rate or volume twice a month, or metering and recording daily injected and produced fluid volumes;

(3) Monitoring the fluid level in the injection zone twice a month;

(4) 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 month;

(5) Manifold monitoring may be used in cases of facilities consisting of more than one injection well with a common manifold. Separate monitoring systems for each well are not required provided the operator demonstrates to the secretary that manifold monitoring is comparable to individual well monitoring; and

(6) A minimum of quarterly monitoring of secretary specified wells within one-quarter mile of the production site to detect migration of recovery fluids from the production zone.

The name, address, and telephone number of the laboratory performing the analyses, and the laboratory identification number are to be provided.
