Mr. Telander: 

As you know, Hanson Brick contracted Mr. Jim Rickun to enter our Mineral Wells stack test data into the 

ERT system. In doing so, Mr. Rickun has been in contact with Mr. Ron Myers who has helped clear up 

some of our confusion. As such, Mr. Myers has provided us with a version of our "Project Data Set" that 

fixed some of the bugs we were encountering. 

During this process, we requested, and received, additional data from the stack tester. I have included 

these three additional Excel files as well as the "Project Data Set" file as corrected by Mr. Myers. Please 

note that you must change the extension on the "HansonBrickMineralWells - ERT Myers" file from .xxx 

to .mdb in order for the ERT program to load the data. 

I hope this helps clarify any discrepancies. As this is the first time we have encountered the use of the 

ERT program, please bear with us as we get through all of the intricate details. 

Thank you.

Subject: Documentation of detection limits 

Dear Mr McKeown, 

As I indicated in my voice message to you this afternoon, additional information is needed regarding the 

procedures used to determine the detection limits in the Mineral Wells stack test report dated 

September 28, 2010. 

Page 4 of Enclosure 3 to the Section 114 letter that was sent to you includes the following requirements 

regarding procedures used to determine analytical detection limits: 

When reporting and calculating individual test run data: 

*For analytical data reported from the lab as "nondetect" or "below detection level;" 

-Include a brief description of the procedures used to determine the analytical detection and instack detection levels: 

 o In the Notes line of Excel emission test spreadsheet template; or 

 o In the Comments line of Lab Data tab in the Run Data Details in the ERT. 

-Describe these procedures completely in a separate attachment including the measurements 

made, the standards used, and the statistical procedures applied. 

The Mineral Wells test report does not appear to include the above required information regarding 

detection limits for each pollutant. Please forward this information to me as soon as possible. 

Sincerely, 

Jeff Telander
