RE: Coulson Excavafing Co., Inc., Application No. M-2005-033 Natural Resource Trustee
Gardels Pit; Adequacy Review #2 !/
Deaz Mr. Coulson,
The Division received your adequacy response to the Division's July 8, 2005 letter regarding the new
permit application for the Gaddels Pit, File No. M-2005-033. The Division has a number of remaining
items that need to be addressed prior to approval of the application.
Rule 6.4.4 Exhibit D-Mining Plan
I. The applicant states that the Pheiff property (just east and adjoining Gaddels) was added to the
Brownwood Permit M-1979-059 as an amendment some time in the late 1980's that added the low
water crossing to connect the Pheiff property to the Brownwood Permit. The Division agrees that the
area was amended, but the application did not contain designs for the low-water crossing. Therefore,
Coulson Excavating Company will need to file a revision to the Brownwood Pit permit addressing
designs of the low water crossing to access the Gardels Pit. Such revision must be approved and
additional bond posted prior to the construction and use of the road and river crossing.
2. The applicant states that vegetation will naturally establish on topsoil piles and will be allowed to
naturally revegetate. Without any revegetation efforts to stabilize the topsoil piles, weeds (such as
annual and noxious) typically encroach on to disturbed areas and can become a problem. In addition,
when the topsoil is redistributed on to the reclaimed areas, weed seeds aze present and may be
distributed throughout the site. Please commit to a temporary seed mixture on the topsoil piles and
state the rate in PLS/acre, application method and the timing of seeding.
3. Please inform the Division if the overflow pipes noted in the sediment containment ponds are subject
to the NPDES permit that will be obtained for the site. Tn several places, the above ground pipes
cross topsoil stockpile areas (Cells A & B) and the haul road (Cell D). Please further explain how
these pipes will function and be situated to cross the topsoil piles and roads to be used as an outlet
structure.
Rule 6.4.7 Exhibit G- Water Information
4. The water lease provided by the applicant in Exhibit G-1 is between the City of Loveland and
Loveland Ready Mix. Please explain and provide further documentation demonstrating how Coulson
Excavating is subject to the terms of the lease.
