Effective immediately, all Site Monitoring Reports (SMRs) for bedrock sites should be completed using the Tier 2 Bedrock Software, version 1.20. For bedrock sites, there is no SMR module within the software program. Annual site monitoring data may be input into the version 1.20 file and software rerun to determine pathway classifications. Please indicate in a cover letter whether the report is a Tier 2 or SMR.

All data for the site, including the most recent sampling event should be entered into the analytical data sections of the bedrock model. This is different than standard Tier 2 modeling, in which data is entered into an SMR module.

If the Tier 2 report was completed in an earlier version, the data should still be entered into the new bedrock software. The June 20, 2001 posting titled "Bedrock Software Version 1.0" required original and revised Tier 2 bedrock reports submitted after July 31, 2001 to be completed using the Tier 2 Bedrock Software, Version 1.

In general, Tier 2 Bedrock modifications were made under the following sections:

• Bug Fix – Soil Gas Maximum x-y Locations
