Tier 2 Bedrock Version 1.20

Following is an update of the Tier 2 Bedrock Software – version 1.20. Tier 2 Bedrock reports (either original or revised) that are submitted after February 15, 2004 must be completed using software version 1.20.  Tier 2 Bedrock reports that are submitted prior to February 15, 2004 may be completed using version 1.0 software.

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.

Tier 2 Report Form - The pages for the Tier 2 Report which are not printed from the software are now fillable PDF forms.

Note: When submitting a bedrock Site Monitoring Report the following additional sections are required to meet annual reporting requirements and should be inserted after Possible Deficiencies (p 25):

  1. Potential Receptor Summary
  2. Receptors Status Change and Site Reclassification
  3. Appendix 1 - Evaluation of Analytical Data (Word document)
