‐ Test Results for EPA Sec 114 ICR for HCl Emission

Testing

Keith,

Attached is the M321 XL file completed for the HCl Method 321 emission testing

we completed on Kiln Number 3 at the Lone Star Industries Inc.

facility in Pryor Oklahoma. We are finalizing the full test report to support

the attached results and should have that submitted to you within the next two

weeks.

As we discussed several weeks ago, Lone Star Industries Inc. has not had

another qualifying kiln available to conduct testing that would produce

results by the March 31, 2010 deadline of the ICR. Further, we do not expect

that status to change. We do expect our Kiln Number 1 at the Pryor facility

to be restarted within the next week and reach normal production within two

weeks. However, this would not present an opportunity for testing until at

least April 5 (assuming testing services are available, which they were not

last we checked). In addition, as we discussed, since Kiln Number 1 is also a

long

‐ dry kiln and would be processing the same fuels and raw materials as

those used during the Kiln Number 3 testing, testing an additional kiln at the

Pryor facility is not expected to produce HCl results significantly different

than those reflected in the attached.

As a result, it is our understanding that the Kiln Number 3 testing at the

Pryor facility will satisfy our obligation to provide the information required

by Sec 114 ICR. If this is incorrect, please let me know.

Regards,

Dan Nugent
