  • ERP Results Analyzer (2007, with minor 2009 update). This user-friendly spreadsheet tool, used in the EPA ERP team's statistical training workshops, helps manually calculate statistical results from ERP.

  • Documentation of Formulas for Sample Planner and Results Analyzer (PDF) (10 pp, 98K) (2007). This background provides the written formulas used in the Sample Planner and Results Analyzer, for reference as needed.

It is a self-installing program that asks an UST owner/operator a series of questions about his/her UST facility. It then generates a customized UST ERP workbook containing regulatory information pertinent to the owner/operator's facility. It is based on the Model Underground Storage Tank Environmental Results Program Workbook (EPA 510-R-04-003), published in June 2004.
