Rule 4.09.1(] 1)(a) The fill shall be inspected for stability by a registered engineer or other
qualified professional specialist experienced in construction of earth and rockfrll embankments
under the direction of a qualified professional engineer at least quarterly throughout the
construction and during the following critical construction periods: (1)removal of all organic
material and topsoil, (2)placement of underdrainage systems, (3) installation of surface drainage
systems, (4) placement and compaction of fill materials, and (5) revegetation.
The subject inspection was a quarterly inspection accomplished throughout construction, not one
of the critical construction periods. The report does not specifically state that a registered
engineer or other qualified professional specialist made the inspection, but infers such by
certification or the report.
Rule 4.09.1(11)(b) The qualified registered engineer shall provide to the Division a certified
report within 2 weeks after each inspection that the fill has been constructed as specified in the
design approved by the Division. The report shall include a description of any appearances of
instability, structural weakness, and other hazardous conditions observed during the inspection.
A copy of the report shall be retained at the mine site.
The site was inspected on June 29, 2004. The report was thus due at the Division on July 13,
2004. It was received at the Division of Minerals and Geology (Division) on July 12, 2004. The
report was timely.
Appearances of instability, structural weakness and other hazardous conditions were not related
in the report. The omission was brought to the attention of the operator as an adequacy item.
These deficiencies were corrected in an amended report of September 14, 2004.
Rule 4.09.1(1 ])(c) See the rules for the text of this rule. This rule applies to photographs of
underdrains. No underdrains were constructed during the report period.
