Binns, Janet <br />From: Watterson, Brian [BWatterson@peabodyenergy.com] <br />Sent: Wednesday, February 24, 2010 8:10 AM RECiEIVEr <br />To: Binns, Janet <br />Subject: Twentymile Coal 2009 Annual Hydrology Report FEB 2 <br />Diviswi. ,- - <br />Janet: Mining and Safety <br />I am requesting an extension of the due date for the 2009 Annual Hydrology Report (AHR) from February 28th to March <br />19th 2010. <br />As indicated in our conversation of yesterday, there are a number of reasons for this request, which include: <br />• Background: When Twentymile was bought by Peabody in 2004, RAG took our oracle hydro-database, saying it <br />was proprietary. The consulting firm (Whiting Group) that developed the database took it to court and after a <br />few years won its right to use the database. We tried to re-create the database in late 2006/early 2007, with <br />some success, but eventually developed problems getting it to function in submitting our raw period of record <br />data. For the last few years we've been hand-entering data into excel spreadsheets for the water year tables <br />and graphs. <br />• Background: In 2007/2008 Peabody St. Louis started looking into developing a company-wide hydro database. <br />In 2009 a consulting firm was hired to work on modifying some existing Equis software for the individual <br />Peabody mines, including Twentymile. This current product still has bugs and is very user unfriendly. Our <br />laboratories have been tasked to enter the last several years worth of historical data in order for us to catch up. <br />Peabody in St. Louis is helping me with getting out the data tables for the AHR. <br />• On Feb 22, 1 finally received an extracted copy of our historical data base (1975 - 2004) from our old consultant <br />(Clark Whiting) who designed our original hydro-database. I emailed you a copy of one of our email <br />communications yesterday. He has not been consulting for a few years, and works for TIC in Houston. We have <br />been trying to get his assistance for several months to extract the historic data. The data is too large to email, so <br />I sent a thumb drive via Fed Ex to my Peabody contact in St. Louis to incorporate in the existing Equis Data base. <br />I'm not sure how long it will take to re-format this data for Equis. <br />• Yesterday I also received a message from our Stream Gaging Consultant (Rivers Unlimited) that they had a <br />computer crash and lost the report they were working on, which presents the results of the two year gaging <br />project. I sent you a copy of their email message yesterday. This may take a week to re-create, afterwhich I will <br />review it, and summarize it in the AHR. The report will be included as an Appendix in the AHR. <br />By next week I'll have a better handle on how long the St Louis Peabody folks need to help me. If we are still having <br />significant delays with using Equis, the March 19 extension will still allow me plenty of time to submit the AHR,, even if I <br />have to hand-enter data again. <br />Thanks for your consideration, <br />Brian Watterson, P.G. <br />Geologist, Environmental Group <br />Twentymile Coal Company <br />29515 Routt County Road # 27 <br />Oak Creek, Colorado 80467 <br />(970) 870-2750
