<br />MINE ID # OR PROSPECTING 10 # M-1980-131
<br />INSPECTION DATE 09/19/2006 INSPECTOR'S INITIALS DEG
<br />OBSERVATIONS
<br />This routine monitoring inspection of Permit Number M-1980-131 (Bunn Ranch Pit) was conducted by Deb E. G6nima of the
<br />DRMS. Representatives from Elam Construction, Inc. -Lisa Lawton and Gayle Lyman and Lafarge West, Inc. -Bruce Daniel
<br />and Jon Sobeski were present during this inspection. The pit is located 1.5 miles east and 1 mile south of Craig, CO, and
<br />currently consists of approximately 133 acres where approximately 50 acres have been disturbed.
<br />Mine entrance signs and permit boundary markers are in place, there are numerous material and topsoil stockpiles on site. The
<br />Yampa River constitutes the southern permit boundary and the fenceline is the northern permit boundary. This site was active
<br />at the time of this inspection, and several stockpiles of various materials were present onsite. Mining began in the western
<br />portion of the site last summer, and a new pit was just opened at the southeastern portion of the site. Topsoil and overburden
<br />have been removed from this new site, but mining-specific operations have not yet begun. In addition to common sand and
<br />gravel operations, re-crushing of asphalt is performed on site, as well as use of a hot plant for asphalt processing and
<br />production.
<br />During the early spring of 2005 (prior to asphalt production -which typically begins in the middle of May) one of the hoses used
<br />to transport diesel fuel across the berms in the hot plant area was chewed through by a rodent. This resulted in a spill of
<br />approximately 650 gallons of diesel fuel. Of these 650 gallons, approximately 100 gallons were contained within the lined
<br />secondary containment berm. However, the other 550 gallons were spilled onto the surrounding soil. Fines were used to soak
<br />up the spill and booms were placed in the Yampa River in order to collect any fuel that had been released into the river. The soil
<br />where the majority of the spill collected was excavated (totaling approximately 500 to 600 cubic yards of material), crushed and
<br />back-burned in the hot plant. The material was sampled before and after it was crushed. Then the material was processed and
<br />asphalt was made out of the previously contaminated material. Approximately 2 feet of additional material was excavated below
<br />the extent of the contaminated plume. As a result of all of the aforementioned actions, numerous precautionary secondary
<br />containment measures have been instituted across the permitted site.
<br />Other items of interest on the site include the use of asoap/detergent as an asphalt release agent to clean the trucks. There is
<br />awash plant on site for the processing of sand and aggregate. And the following agents and petroleum products were in use
<br />within the permit boundaries: oil (in the tan AC tank), diesel (in the yellow tank), tackifier (in the black trailer), burner oil
<br />(recycled/refined motor oil) (in the red and white-striped tank), and asemi-trailer-size generator. All of these agents were
<br />properly impounded and the surrounding area was protected from potential hazardous spills through the rigorous employment
<br />and maintenance of secondary containment structures (as seen in photos 2, 4, and 5).
<br />During this inspection the operators mentioned interest in possibly submitting a release request for the easternmost ponds. The
<br />Army Corps of Engineers (ACE) designed plans as a result of the need for an emergency repair that were followed for the
<br />construction of several riprap lined spillways far these ponds. Vegetation throughout this portion of the permit area is well-
<br />established and conditions in this area appear to be of a releasable state. Therefore, this inspection report maybe utilized as
<br />authorization to release this portion of the site if a formal acreage release request is submitted to the Division within 60 days of
<br />receipt of this inspection report. However, concurrence with other state agencies as well as ACE may be necessary prior to
<br />formal release approval.
<br />All activities and completed work at the time of inspection appeared to follow the guidelines and regulations set forth by the
<br />state and the mining and reclamation plans for the pit, and no problems are noted for this site. The site is stable and no
<br />disturbance was observed outside of the approved permit boundaries. For future reference, this site is correctly positioned in
<br />the DRMS online GIS.
