2.1.1 Narrative
SWPPP controls and BMPs are being inspected daily. Wood from the mill and barn building demolition was sorted and excess
scrap metal was removed and the wood was placed in the impoundment. Dave Rees, OSC, was onsite on October 28, 2014
to review progress. Onsite options were discussed regarding the approach of
breaking up the wood from the building demolition. It was decided by Mr. Rees and Jim Fricke
that the wood can be broken down by using tracked heavy equipment (D6 Dozer or
equivalent). This change from the original workplan was due to the safety issues raised by the wood chipping operator due to the metal remaining in the mixed debris. A demonstration of this
mechanical crushing technique was prepared by REMC and approved by Mr. Rees.
Approximately 1,000 cubic yards (cyds) of material was
removed from the slough area west of Goldfield Mine Road and placed on the
impoundment. Approximately 800 cyds of clean fill material was excavated and
used to reclaim the slough area and insure a 3:1 slope ratio was achieved along
the Goldfield Mine Road. On October 29, Northwest Liner arrived on Site and
deployed the HDPE liner. Approximately 1,000 cyds of high-lead soils (>9,999
ppm lead) were excavated from the mill area and placed on the HDPE liner. It is
anticipated that Northwest Liner will weld the HDPE liner the week of November
3, 2014.
On October 30th approximately 80 cubic yards of scrap
metal was hauled off this site by Real Steel Recycling, it is anticipated that
two more loads are required to complete scrap metal removal.
An REMC representative collected samples from the following
drums for analytical testing: a drum labeled Cyanamid II found in the “oil
shop” on-Site and the reinforced drum containing an unknown white solid. The
samples were delivered to Emerald Services on October 31, 2014.
Sampling:
Air samples were collected from three locations on October 30th.
Air samples were sent for lab analysis on October 31, 2014.
Analytical results for the soil and water samples collected
on October 13 and October 15, respectively, were received on October 31, 2014.
The analytical results for soil and surface water samples are attached to this
report as Table 1 and Table 2, respectively.
Analytical results for the following air samples were
received on October 31, 2014. The analytical results are presented below:
