In 329 IAC 9-5-5.1, the rule requires that the owner and operator submit information in a manner that demonstrates the applicability and technical adequacy of the information. The rule further states that the information shall be provided in a format as required by the agency. The rule discusses sampling information, laboratory procedures, and documentation requirements. In order to satisfy the rule requirements set forth in 329 IAC 9-5-5.1(F), 329 IAC 9-5-6, 329 IAC 9-5-7, 329 IAC 9-6-2.5 and elsewhere in 329 IAC 9, the Minimum Data Documentation Requirements (MDDRs) were developed.
While this level of data documentation is a subset of the complete quality assurance and quality control (QA/QC) documentation generated by the analytical method, it is adequate to allow the Office of Land Quality to provide meaningful evaluation and interpretation of analytical results. The MDDRs and other IDEM QA/QC requirements are presented in Section 3.9.1 of the Remediation Closure Guide. MDDRs should be provided with any LUST program related correspondence which contains analytical results. This requirement applies to all analytical data submitted to IDEM on or after March 3, 2003.
The following are some clarifications regarding these sampling requirements: This documentation is required for the UST Closure. Assessment Equipment blank samples are NOT required UNLESS sampling equipment requires decontamination. This documentation is NOT required for influent and effluent samples collected for an operating pump-and-treat remediation system with the EXCEPTION of those influent and effluent samples collected during the quarterly monitoring event for the Corrective Action Progress Report (CAPR).
The remaining, monthly influent and effluent sampling required for a National Pollutant Discharge Elimination System (NPDES) general permit should be reported in a tabular format, but no other documentation is required. These requirements apply to all LUST sites including those using: 1994 UST Branch Guidance Manual, 2001 Risk Integrated System of Closure (RISC) Technical Resource Guidance Document and User's Guide, and 2012 Remediation Closure and Program Guide.
