Re: Tierra Piedra Gravel Pit,
110c Permit Application, Preliminary Adequacy Review Letter.
- —(�
Dear Mr. Clark,
This office has completed its technical adequacy review of your gravel pit permit application. There are several items
that must be clarified or corrected before we may consider an approval decision. These items are listed below in the
order of the application exhibit to which they pertain. This information is needed pursuant to the rules and will be
important to estimate the bond amount. Please respond to all items, and label them to facilitate their inclusion in the
permit file. Portions of the application not referenced in this letter are considered to be adequate at this time.
Application Form, Item 5
The description of commodities and incidental commodities to be excavated at the site does not include topsoil, though
an excess of it will be generated and presumed to be removed from the site. Please include topsoil in the appropriate
blank(s) of this portion of the application.
Exhibit B — Site Description (Rule 6.3.2)
The exhibit does not include the new fence along the eastern edge of the pit area. It is not clear if it will be a
permanent feature (e.g., remain after reclamation) but it should be noted in the site description. The segments of the
old fence that were observed on or near the southern and southwestern boundaries should likewise be included.
The proposed permitted area includes 1.6 acres of new roadway. Its northern terminus is within 200 feet of an existing
gas well facility, but no information is provided about the well. Please include the required information in this exhibit.
(Further items concerning the well are included in following paragraphs.)
Please clarify the depth (or seasonal range of depths) to the expected water level of the pond.
The map does not depict the stand of mature cottonwoods that exists on or near the western edge of the site. The small
pre -law pit that was observed in the south end of the site is also not shown or described. Please provide a revised map
that depicts at least the estimated locations of the margin of the cottonwoods and the old pit.
There is a natural Swale or drainage outlet for the low bench area proposed for this pond. It was observed to be
adjacent to the old pit that exists in the southern end of the site. The application does not include description of this
feature, though it is considered important due to the shallow topography of the site and its relation to the river
elevation. Please clarify whether this swale will be filled or retained, or utilized as a future pond overflow structure.
(Please see a further comment on the swale under Exhibit E, below.)
