INSPECTOR'S INITIALS WHE
This partial inspection was conducted by Wally Erickson from the DMG field office in Durango, 1474 Main Avenue, Room 207,
Durango, CO 81301-5182, phone [phone]. Mr. John Dillon, Sandco, accompanied the DMG inspector through out this
inspection. The 112 Regular permit was issued on 8127187, for 67 acres affected area. M-87-064 is approved for gravel excavation
from the Animas River channel and material processing areas located on the west bank of the river. The 67 acres enclosed areas
previously affected under permit numbers M-79-016 and M-80-130. The Dalton Land & Cattle operation, is located immediately
north of County Read 2521Trimble Lane) crossing of the Animas River, in portions of the following sections of T36N, R9 W, NMPM:
S 1 /2 of the SE 1 /4 of Section 10;
SW 1/4 of the SW 1/4 of Section 11; and
NE 1/4 of the NW 1l4 of Section 15.
Access to the permit area from Trimble Lane is controlled by locked gate and fence. Mine identification sign was posted at the mine
entrance at Trimble Lane. Affected area was clearly delineated along the south, west and northwest boundaries. Boundary markers
were not inspected for the east and northeast boundaries.
Bridge abutments and channel banks were well protected by large sandstone riprap at the Trimble Lane bridge. Riprap extended
upstream from Trimble Lane bridge along the west bank for approximately 700'. Low water crossing, located at the north end of
the stockpile/processing area, was intact and consisted of nine 24" diameter metal pipes. One dozer and excavator were located
on a gravel bar within the river channel at the north end of the affected area. Dozer end excavator were preparing haul road for
material transport to stockpile/processing area. Channel bank showed evidence of erosion at two northern locations within or
adjacent to the permit boundary. Erosion of the channel banks appeared to have occurred during high water season of 1995.
Operator indicated that eroded sections of channel bank within the permit area were to be backfilled and stabilized prior to high
water season.
Six fuel tanks were located in the fuel storage area. Three of the six tanks were approximately 12,000 gallon capacity. The three
12,000 gallon tanks were sitting on the ground, each contained fluids. One 1,600 gallon tank was also setting on the ground and
appeared to be empty. Two 500 gallon elevated tanks, one contained fluids. All six tanks appeared intact, no evidence of rupture
or leaking was observed. Spill prevention/spill containment controls were not evident for any of the six fuel tanks. One 500 gallon
elevated fuel tank was located at the material screening/crushing area, tank appeared intact. Sixteen 55 gallon drums were scattered
near the shop area, several drums contained fluids. Drums appeared intact, no evidence of rupture was observed. One 1,250 gallon
tank was located brhind the shop, operator indicated that the 1,250 gallon tank contained waste oil. Waste oil tank appeared intact,
no evidence of rupture or leakage was observed. Spill prevention/spill containment controls were not evident for the waste oil tank
or any oT the scattered 55 gallon drums. All fuels, lubricants end chemicals need to be stored in a controlled manner, at a designated
location, with adequate spill prevention and spill containment controls. Spill containment controls typically include measures such
as construction of a containment berm surrounding each fuel tank or fluid storage area. Berm surrounding fuel tanks should enclose
sufficient area to ensure containment of volume equivalent to tank capacity. Containment areas should be lined with an impermeable
liner to ensure spilt fuel or fluids not escape and degrade quality of ground and surface waters (Rules 3.1.6 and 3.1.71.
Two sediment ponds are depicted on the Mine Plan map, by Bryan L. Queen PE-PLS, dated 5/2/93. The northern most sediment
pond was located immediately east oT the tire stockpile area. Sediment pond adjacent to tire stockpile area appeared to be little more
that a depression containing cleanings from concrete trucks. Larger sediment pond was located immediately southeast of the
concrete plant and appeared to treat processing water. Both ponds were not holding water during the time of this inspection.
