  1. Remediation Programs Update MSECA Quarterly Meeting March 13, 2012

  2. Today’s Updates • New Transition Policy • State Cleanup: Independent Cleanup Process • Responsible Party Transfer Law • Organizational Changes

  3. New Transition Policy • In general, where 328 IAC and 329 IAC make reference to RISC, IDEM will interpret that in terms of the relevant component of the Remediation Closure Guide (RCG).

  4. Examples • Where 329 IAC 7.1-2-9 defines No Further Action Letters in terms of RISC closure levels, IDEM will interpret that as completed remediation objectives. • In 329 IAC 7.1-4-1 and in 328 IAC 1-4-1, where these rules say that sites will be prioritized based upon identification or detection of any contaminant above “RISC residential default cleanup levels,” IDEM will interpret that as “RCG residential screening levels”. • Where this section discusses: surface soil and direct contact exposure pathway as defined or further explained in RISC,” IDEM will interpret that as meaning those explanations provided in the RCG. RISC cleanup standards for the appropriate land use will be interpreted as risk-based remediation objectives.

  5. Examples (cont.) • Where 328 IAC 1-1-5.1 discusses emergency actions in terms of RISC residential ground water cleanup objectives, IDEM will interpret that as RCG residential screening levels. Where 328 IAC 1-3-5 discusses reimbursable costs associated with transitioning to RISC, IDEM will interpret that as transitioning to the RCG. • Where 328 IAC 1-1-5.1 discusses costs for remediation of contamination not shown to be at concentrations exceeding the risk integrated system of closure (RISC) as described in IC 13-23-8-4(a)(4)(A)(ii) industrial cleanup standards, IDEM will interpret that as risk-based remediation objectives appropriate for industrial land use as discussed in the RSC. Off-site contamination at concentrations exceeding RISC residential cleanup standards will be interpreted as off-site contamination exceeding residential screening levels.

  6. Program Transition Milestones • A party or parties may choose to use either previously applicable guidance or the new guidance if the following program-specific milestones are met before or during a transition period:

  7. Brownfields • A Remediation Work Plan has been submitted or a completed request for a Comfort/Site Status/No Further Action letter has been logged by the program.

  8. RCRA Permitting • A closure plan has been submitted to IDEM.

  9. LUST and ELTF • A Corrective Action Plan (CAP) has been submitted to IDEM. • ELTF will continue to use the industrial ground water numbers until there is a rule change.

  10. State Cleanup • A Remediation Work Plan (RWP ) has been submitted to IDEM.

  11. Voluntary Remediation • A Voluntary Remediation Work Plan (RWP) has been submitted to IDEM.

  12. Additional Comments • If the above milestones have not been met before the end of the transition period, then IDEM will refer to current guidance and applicable rules and laws when evaluating proposed Remediation Work Plans and remediation objectives. •  Sites with approved work plans may still close using their approved remediation objectives.

  13. Additional Comments (cont.) • A party or parties that do not have an approved work plan and are utilizing an older guidance document may propose site-specific approaches or choose to change to the most current guidance at any time. However, • The scientific methodology and any inputs used to evaluate risk or to establish new remediation objectives need to be current at the time they are presented to IDEM for approval. • Whether using an older guidance document or the most current guidance, site-specific approaches, including the calculation of new site-specific remediation objectives, will be evaluated using currently accepted methodology and best available science.

  14. Old VRA, New Non-default # • You may continue to use the tables of numbers that your VRA has locked you into. However, • New non-default calculations must use current science. • If you already have an approved RWP, any non-default numbers approved under that RWP are still good.

  15. Independent Cleanup Process (ICP) • Total Sites: 158 • Active: 119 • Completed: 36 • Denied: 3

  16. ICP (cont.) • IDEM now considering Medium Priority petroleum in ground water sites. • No free product. • No hazardous or hazardous/petroleum mixes. • No completed exposure pathways.

  17. ICP (cont.) • IDEM will allow a 10 times residential groundwater number for closure at industrial- commercial land use properties. • Industrial direct contact numbers still exist. • Will now allow ERCs on ICP petroleum ground water sites. • Use the template. • ICP is voluntary.

  18. Responsible Party Transfer Law(RPTL) • Changes to RPTL will require the reporting of ERCs when property is transferred.

  19. Organizational Changes • New Institutional Controls Compliance position. • New UST Branch.
