  8. Memphis Depot Regulatory Dates • RCRA Facility Investigation by EPA in January 1990. • Issued RCRA Part B permit by TDEC DSWM in September 1990 for container storage unit. • Issued HSWA permit by EPA in September 1990 for corrective action of SWMUs and AOCs. • Added to Federal NPL on October 14, 1992 with HRS score of 58.06 [57 Fed.Reg. 47180]. • FFA between Defense Logistics Agency (DLA), EPA and TDEC March 6, 1995. • RCRA Part B permit terminated October 1998. • TDEC & EPA agree to terminate HSWA permit in January 2005 due to deferral to CERCLA cleanup.

  9. CERCLA Cleanup Actions for MI • Remedial Project Managers: DLA – Mike Dobbs; EPA – Turpin Ballard; TDEC – Jim Morrison. • 1995 thru 2000 conducted RI/FS and several interim actions to remove contaminated surface soil. • ROD for MI (February 2001); selected remedy includes bioremediation of VOC [PCE & TCE] contaminated groundwater and land use controls (LUCs). • LUCs to prevent residential use/daycare facilities and production/consumptive use groundwater wells. • Final Remedial Design (July 2004) included Land Use Control Implementation Plan (LUCIP).

  10. MI Land Use Restrictions • Land Use Control Objectives: • Prevent direct contact/ingestion of surface soils contaminated with dieldrin, arsenic and lead; • Prevent ingestion of groundwater contaminated with VOCs. • Land Use Restrictions: • No residential use or other child-occupied facilities, including daycare; • No production/consumptive use of groundwater or drilling wells.

  11. Summary of MI LUCs • Deed and Lease Restrictions: • Property transfer documentation includes land use restrictions; • Lessee (DRC) subject to “environmental protection provisions” in lease which restrict use. • Notice of Land Use Restrictions: • Recorded at Shelby Co. Register of Deeds pursuant to TCA 68-212-225; • Identifies location of residual contamination and specific use restrictions.

  12. Summary of MI LUCs con’t • Zoning Restrictions: • Depot located in Light Industrial (I-L) zoning district; • Memphis Land Use Control Board administers and enforces zoning ordinance. • Groundwater Well Restrictions: • Shelby County Well Construction Code prohibits installation of drinking water wells within half-mile of designated boundaries of Superfund site. • Golf Course Fence: • Preclude casual access by public passerby and prevent unauthorized uses.

  13. Notice of Land Use Restrictions • Includes legal description of the site. • Identifies: • the location and dimensions of the areas of potential environmental concern with respect to surveyed benchmarks; • the type, location, and quantity of regulated hazardous substances known to exist at the site; • the specific restrictions on the current or future use of the site. • Once filed, restrictions enforceable by any owner and local government agency with jurisdiction. • Copies provided to EPA, TDEC, City of Memphis, Shelby County Dept of Health, DRC, USACE, BRACO.

  15. LUC Monitoring and Site Inspection • Monitoring frequency and responsible entity provided in Table 1 of LUCIP. • Part of CERCLA 5 Yr. Review process; report certifying effectiveness of the remedy including LUCs. • Army may arrange to have TDEC or 3rd party conduct required monitoring but retains responsibility. • Annual site inspection to ensure land use restrictions are being followed; checklist and certification. • If deficiency/violation, then Army will inform EPA & TDEC within 72 hours and undertake corrective action.

  16. LUC Modification and Termination • Determination to modify or discontinue LUC will be made by Army with approval by EPA and TDEC. • Decision to modify/end LUC will be documented and placed in Administrative Record file. • Transferee must submit request in writing to Army/EPA/TDEC if changes to LUC or use restriction. • Under TCA 68-212-225(e) Notice may be made less stringent/canceled with approval of TDEC Commissioner. • LUCIP may be terminated by Army/EPA/TDEC if remedial goals met and LUCs no longer required.

  17. Why is this LUCIP important? • First document approved by EPA and Army HQ after DoD/EPA CERCLA Post-ROD Authority LUC dispute. • Consistent with Navy/EPA Land Use Control Principles and EPA Federal Facility LUC Checklist. • Coordinated review with DLA, Army (HQ, ELD, AMC), BRACO, TDEC, EPA Region 4 and EPA HQ. • Army Guidance incorporates many aspects of the LUCIP including specific language in sample RD document. • Provides model for other federal agencies at similarly situated sites.

  18. Summary Statements • All land use controls are local, so determine whether existing mechanisms, (e.g. zoning or excavation permit) can be utilized. • LUCs should be “layered”, meaning use multiple LUCs that help ensure remedy effectiveness. • Start dialogue with document reviewers (especially regulators) to facilitate approval. • Understand relevant EPA and DoD/Army Guidance and State laws/regulations. • Enlist the assistance of knowledgeable attorney to help draft required documents such as deeds, Notices etc.
