Dear Mr. Messey:

	Please understand that the purpose of our review process is
to
assist you in your compliance with the applicable disclosure
requirements and to enhance the overall disclosure in your filing.
We look forward to working with you in these respects.  We welcome

Form 10-K for Fiscal Year Ended December 31, 2005

General

1. Please correct your Commission File Number indicated on the
cover
of your annual report to be 333-107569-03, rather than 1-13105,
which
corresponds to your parent company and not to you.


Management`s Discussion and Analysis of Financial Condition and
Results of Operations

Contractual Obligations, page 37

2. We note that you have not included certain long-term
liabilities,
such as postretirement benefits, asset retirement, workers`
compensation, and other non-current liabilities, in your table of
contractual obligations.  Item 303(5)(i) of Regulation S-K
requires
other long-term liabilities that are reflected on your balance
sheet
under GAAP to be listed in the table.  If you believe the nature
of
these other long term liabilities differs substantially from those
presently shown, you may opt for both quantification and
discussion
of the excluded items in a narrative adjacent to the table.
Further,
please include a total column aggregating the obligations in your
table.

Financial Statements

Statements of Cash Flows, page F-5

3. We note that you have recorded a cash outflow of $108,600,000
for
capital expenditures in the investing section of your statement of
cash flows.  Please tell us how this amount reconciles to the
changes
depicted in the related line items on your balance sheet.

Note 18 - Cash Flow, page F-18

4. We note that you report increases in receivables from Arch
Coal,
Inc. within the line item `Changes in operating assets and
liabilities` in calculating the cash provided by or used in
operating
activities in your Statements of Cash Flows.  However, in
discussing
the increase in cash provided by operating activities in 2005 on
page
36, you identify as a factor in this increase, "...the significant
increase in our receivable from Arch Coal in 2004 which resulted
from
the borrowings that we made in 2004 that were loaned to Arch
Coal."
While the logic in your attribution is unclear, given this
disclosure, coupled with that of your loans to Arch Coal on pages
37
and F-16, clarifying that this receivable is interest bearing and
payable on demand, we would expect to see these transactions
classified as investing activities in your Statements of Cash
Flows
in accordance with paragraph 17(a) of SFAS 95.  Accordingly,
please
amend your financial statements to comply with this guidance or
explain to us why you believe it does not apply to you.

5. We note that you have recorded prepaid royalties as cash flows
from investing activities on your Statements of Cash Flows which,
we
understand from your disclosure in Note 2 on page F-8, are
attributed
to the rights to leased coal lands recoupable against your
production.  It is unclear why you have characterized this
transaction as cash flows used in investing activities since
changes
in prepaid assets on the balance sheet and amounts expensed to
cost
of sales would ordinarily be reflected in operating cash flows.
Please tell us why you believe these payments should be considered
acquisitions of property; describe the mechanism by which such
payments are recouped, and identify the particular characteristics
you believe differentiate these arrangements from typical royalty
payments that should be reported as operating cash flows.
Further,
for each year presented, tell us how much of the prepaid assets
recorded were subsequently expensed in the same period.

Engineering Comments

Properties, page 27

6. In your "Our Reserves" section, you indicate that your most
recent
third party review of your reserve estimates was conducted by Weir
International Mining Consultants in February 2006.  Please provide
our engineer with a copy of this report.  If it is available in
pdf
format, please provide it on a disk.
