RE: Review of Piceance Soil Remediation Facility: MIPA -7607
Dear Kathy:
EXHIBIT
This office has performed a review of the documents provided for the Major Impact Review
Application for the Piceance Soil Remediation Facility. The submittal was found to be thorough
and well organized. The following comments were generated:
1. The Applicant should address how the site soils precludes installation of a liner to protect
groundwater from the proposed activities.
2. The Applicant states that there was an evaluation of the site soils and directs the reader to the
Geohydrology report. The Geohydrology report in section 5.0 states that site specific data is
still needed. If this evaluation has been performed, results should be provided for review.
3. There are two options proposed for the access road as it crosses a natural drainage. The
culvert crossing would appear to be the preferred option to avoid times of impassability due
to runoff.
4. The traffic report states that an auxiliary turn lane will be required later in the projects life
but that it coincides with the estimated life of the project. This would be adequate if the
closure of the site and the traffic threshold warranting the turn lane coincide but that is
unlikely. A condition of approval should be included that requires the construction of the
turn lane if the threshold is reached prior to the closure of the facility.
5. The Applicant proposes to provide three monitoring wells. Location of monitor wells are
generally described. The Applicant should determine actual locations and obtain necessary
permits.
6. The Applicant is in various stages of permitting with jurisdictional entities. Copies of
permits should be provided to Garfield County as there are obtained.
Feel free to call if you have any questions or comments.
