instructed during the inspection to establish sediment control measures as designed, or request
a revision to propose alternatives if the currently approve measures cannot be implemented. It
did not appear that activities to date had resulted in sediment leaving the site and no off-site
impacts were apparent. No erosion or evidence of instability was observed.
West Portal Explosives Area
The West Portal Explosives Area (Powder house and Caphouse) is the former location used for
explosives storage. The .76 acres of disturbance was reclaimed in 2006. Control of runoff
from the area was discussed in the cover letter for TR-23 in response to Ten-Day Notice 91-02-
370-003. The operator pointed out in that letter that the area was up gradient of a clean water
diversion ditch that emptied out into a large sump area prior to entering a culvert that would
pass flow to the Purgatoire River. A rough calculation and estimate provided by the operator of
both the sump area and the small amount of possible storm runoff indicated the sump area
would easily contain any storm runoff. It was also stated by the operator that the sump could
be constructed at the location of the disturbance, if necessary. The area is also mentioned in
the Stormwater Management Plan in Exhibit 22 of the approved permit under Part 2, items #8
and #9 and in the table included in Part 5, item b. The area is not shown as an SAE on Map 12
West Portal Area — Roads, Utilities, and Facilities, 3/24/2011 of the approved PAP. Field
inspection found a well vegetated area (see photographs) and some evidence that alternative
sediment control measures were implemented at some time in the past, likely at final
reclamation in 2006. No erosion or evidence of instability was noted.
Access Roads to SAE Areas
While this category of SAE was included in the Stormwater Management Plan in Exhibit 22 of
the approved permit under Part 2, item #13 and in the table included in Part 5, item b, access
roads do not normally fall under Rules 4.05.2(3) for small areas not reporting to sediment
ponds. Access roads are covered by Rule 4.03 and not considered SAE's. However, for those
areas like the West Portal Pumphouse and the West Portal Water Tanks where small sections
of roads were used to access the site, these areas were found unremarkable and identical with
the observations of the site(s) themselves.
