N.M. Admin. Code § 19.8.8.803 - GEOLOGY DESCRIPTION
A. The
description shall include a general statement of the geology within the
proposed permit area accompanied by appropriate maps and cross-sections down to
and including the first aquifer to be affected below the lowest coal seam to be
mined.
B. Sampling requirements.
(1) Test borings or core samples from the
proposed permit area shall be collected and analyzed down to and including the
stratum immediately below the lowest coal seam to be mined to provide the
following data in the description:
(a)
location of subsurface water, if encountered;
(b) logs of drill holes showing the
lithologic characteristics and thickness of each stratum and each coal
seam;
(c) physical properties of
each stratum within the overburden including compaction, erodibility, and if
this material is to be used as topdressing, potential soil texture;
(d) for surface mining activities, chemical
analyses of a composite sample of each stratum within the overburden and the
stratum immediately below the lowest coal seam to be mined and for underground
mining activities, chemical analyses of the stratum immediately above and below
the coal seams to be mined to identify at a minimum, those horizons which
contain potential acid-forming, toxic-forming, or alkalinity producing
materials and a composite sample from each stratum shall be analyzed for the
following parameters:
|
Aluminum (Al) |
Cyanide (CN) |
|
|
Arsenic (As) |
Fluoride |
Silver (Ag) |
|
Barium (Ba) |
Iron (Fe) |
Sulfate (SO4) |
|
Boron (B) |
Lead (Pb) |
Uranium (U) |
|
Cadmium (Cd) |
Manganese (Mn) |
Vanadium (V) |
|
Chromium(Cr) |
Mercury (Hg) |
Zinc (Zn) |
|
Cobalt (Co) |
Molybdenum (Mo) |
Radioactivity |
|
Copper (Cu) |
Nickel (Ni) |
Radium Ra226 |
|
Selenium (Se) |
||
|
Radium Ra228 |
(e)
If this material is to be considered for use as topdressing, analyses for the
parameters necessary for plant growth shall be performed, in addition to those
listed above, and shall include at a minimum the following:
|
Calcium (Ca) |
Sodium (Na) |
|
Chloride |
Carbonate (CO3) |
|
Magnesium (Mg) |
Bicarbonate (HCO3) |
|
Phosphorous (P) |
Nitrate (NO3) |
|
Potassium (K) |
Sodium Adsorption Ratio (Adjusted) (SAR) |
|
pH |
(f)
A demonstration of the suitability of topsoil substitutes or supplements in
Subsection E of
19.8.20.2005 NMAC shall be based
upon analysis of the thickness of soil horizons and/or geologic strata, total
depth, texture, percent coarse fragments, pH, and areal extent of the different
kinds of soils. Analyses of additional parameters or additional data may be
required by the director.
(g) If
the applicant can demonstrate that the analyses of any particular parameter is
of little or no significance in the proposed permit area, then such
parameter(s) may be waived upon approval of the director;
(h) analysis of the coal seam, including, but
not limited to an analysis of the sulfur, pyrite, and marcasite
content.
(i) The applicant shall
submit a proposed sampling plan to the director for approval.
(2) If required by the director,
test borings or core samplings shall be collected and analyzed to greater
depths within the proposed permit area, or for areas outside the proposed
permit area to provide for evaluation of the impact of the proposed operations
on the hydrologic balance.
(3) An
applicant may request that the requirements for a statement of the results of
the test borings or core samplings be waived by the director. The waiver may be
granted only if the director makes a written determination that the statement
is unnecessary because other equivalent information is accessible to him in a
satisfactory form.
