Title
Approval of a Restrictive Deed Covenant on Southeast Area Park
Memorandum
The City of Ann Arbor maintains a closed landfill located at the southwest corner of Platt and Ellsworth Roads. A release from the Ann Arbor landfill (AALF) of the volatile organic compound vinyl chloride was discovered in 1992 in Southeast Area Park. The City of Ann Arbor has been actively recovering the affected groundwater and has been completing quarterly groundwater sampling to monitor the plume in accordance with an agreement with the Michigan Department of Environmental Quality (MDEQ).
The City of Ann Arbor is finalizing an Offsite Remedial Action Plan (Offsite RAP) with MDEQ for final remediation requirements. As part of this process, MDEQ requires that certain parcels have a groundwater use restriction attached to the property.
The purpose of this Offsite RAP is to: 1) describe how the practical and technically feasible remedies presented in the Onsite Remedial Action Plan (approved by the State in March, 1994) for the AALF and subsequent documents address offsite groundwater impacts; 2) present a schedule to implement and maintain the remedies; and 3) explain how the remedies address relevant offsite exposure pathways. This Offsite RAP follows the MDEQ Remediation and Redevelopment Division's Suggested Format and Content for Remedial Action Plans and Plans for Interim Response Activities Designed to Meet Criteria, (March, 2004). The Offsite RAP was prepared pursuant to the requirements of Section 20120a(1) of Michigan's Natural Resources and Environmental Protection Act (NREPA), 1994 Public Act (PA) 451, as amended. Potential exposure pathways are evaluated and compared to applicable criteria outlined in the MDEQ Remediation Division, Operational Memorandum No. 1: Part 201 Cleanup Criteria and Part 213 Risk-Based Screening Levels, dated March 25, 2011 (Part 201 Criteria) for residential groundwater impacts. This Offsite RAP demonstrates how Part 201 and Part 115,...
