Dear Mr. Dillie:

Finally, all the various items to address your adequacy letter have been developed or completed. Actually, most of
the response has been completed for some time. The last item that was holding up the entire response was the
agreement between the company and Detta Helmsing regarding her objection to the well permit application. That is
noun completed and the responses can be provided for your review.
Please note that this letter and its contents are being sent from Transit Mix rather than from myself. I will be gone
for the first tvo weeks in October and the full signed agreement with Ms. Helmsing was not ready by the time I was
leaving. The date of this letter is being entered manually once the agreement is completed and signed. If you need to
discuss these responses you may call my office phone. Your call will automatically be forwarded to my cell phone. I
may not always be available but messages will follow me so I can respond as soon as I am back in a digital phone
area and I receive the message. Don't hesitate to call if you need to.
The responses to follow are consistent wide your format and numbering. The entire question is only summarized
rather than repealed.
Item 1 - Exhibit C - (summary) Include power and commun[cation lines on maps.
Response: After reviewing your question and the permit maps, there did not seem to be much point in
replacing all the maps. Therefore, only two were modified to include this information. Those are Exhibit C-2 Surface
Owners and Exhibit C-4 Phase 1 Detail Map. It appeared the inforration was most relevant to these two maps. The
Aquila power line along US 50 and into the site are shown on both maps. Only part of the line into the site is owned
by Aquila, the rest of the lines throughout the site are owned by the operator. The revisions are noted in a small
squaze near the title block. These maps should replace the original application maps.
In addition to the inclusion of the power lines on the map, there is a notarized letter of agreement
between Transit Mix of Pueblo and Aquila regarding any damages to the line. That letter is included in the additional
information. For your information, Aquila is what was' formerly known as West Plains Energy.
Item 2 -Rule 3.1.5 - Backfilling - (summary) Question regarding compaction of backfilled slopes.
Response: The customary approach to constmcting these slopes and the method that has been used in
creating similar slopes at the Pueblo West Pit, is' to use scrapers to lay in the material in lifts. These lifts are only a
few inches thick. Although a separate compaction step is nor used, this method of creating the slopes has been
shown to be acceptable and stable. Furthermore, after the slope is created with scrapers, a dozer is used to grade the
outer slope of the fill. This- provides additionail compaction. Because the slopes will be no steeper than 3:1, and
