17.24.804 ALLUVIAL VALLEY FLOORS: MONITORING
(1) An environmental monitoring system must be installed, maintained and
operated by the permittee on all alluvial valley floors during strip or
underground coal mining and reclamation operations and continued until all
bonds are released in accordance with ARM 17.24.1114. The monitoring system must provide sufficient information to
allow the department to determine that:
(a) the agricultural utility and production of the
alluvial valley floor not within the affected area is being preserved;
(b) the potential agricultural utility and
production on the alluvial valley floor within the area the land affected has
(c) the important characteristics supporting the
essential hydrologic functions of the alluvial valley floor in the affected
area have been reestablished after mining;
(d) the important characteristics supporting the
essential hydrologic functions of an alluvial valley floor in areas not
affected are preserved during and after mining;
(e) farming on lands protected under ARM 17.24.802
is not being interrupted, discontinued, or precluded; and
(f) the operation is not causing material damage
to the quantity or quality of water in the surface or underground systems that
supply alluvial valley floors protected under ARM 17.24.802.
(2) Monitoring must be performed at adequate
frequencies, to indicate long-term trends that could affect agricultural use of
the alluvial valley floors.
(3) Monitoring must be performed during operations
to identify characteristics of the alluvial valley floor not identified in the
permit application and to evaluate the importance of all characteristics
requested by the department.
(4) All monitoring data collected and analyses
thereof must routinely be made available to the department.
