Van Milligen, City Manager SUBJECT: Environmental Covenant: Old City Garage Site, formerly Peoples Natural Gas DATE: August 31, 2015 City Attorney Barry Lindahl recommends City Council approval of a Resolution approving an Environmental Covenant and Termination and Release of Property Restriction for the Old City Garage Site, formerly People Natural Gas. The practical impacts of the covenant for the City are twofold: (1) the City must ensure its use of the property complies with the terms of the covenant, and (2) the covenant limits the future use of the property and therefore makes it less attractive to future buyers. The City's plans for the future use of the property are to construct a bus transportation facility with incidental office use. This specific use has already been approved by EPA and would meet with the requirements of the covenant. I concur with the recommendation and respectfully request Mayor and City Council approval. Mic ael C. Van Milligen MCVM:jh Attachment cc: Barry Lindahl, City Attorney Cindy Steinhauser, Assistant City Manager Teri Goodmann, Assistant City Manager HE CITY OF DUB E MEMORANDUM Masterpiece on the Mississippi BARRY LINDAHL CITY ATTORNEY To: Michael C. Van Milligen City Manager DATE: August 28, 2015 RE: Environmental Covenant: Old City Garage Site, formerly Peoples Natural Gas Attached is a resolution approving an Environmental Covenant and Termination and Release of Property Restriction for the Old City Garage Site, formerly Peoples Natural Gas. The City of Dubuque is the current owner of environmentally contaminated property with a local address of 925 Kerper Boulevard, Dubuque, Iowa. The property was previously owned by Peoples Natural Gas, who among others, contributed to the contamination of the site. For that reason, it is commonly known as the Peoples Natural Gas Site (the Site). On April 19, 1989, the U.S. Environmental Protection Agency (EPA), pursuant to its authority under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA), issued an administrative order for the cleanup and continued monitoring of the Peoples Natural Gas Site. Pursuant to that order, EPA required the City of Dubuque to place intuitional controls on the Site in the form of a deed restriction, which was recorded in 1991. Subsequently, in 2005, Iowa passed the Uniform Environmental Covenants Act (the Act), which allowed persons to restrict the use of contaminated property in perpetuity by executing and recording an environmental covenant. Following the enactment of the Act, environmental covenants have replaced deed restrictions as the preferred institutional control on sites where contamination will remain on the property. On September 25, 2013, EPA issued an Amendment to the Record of Decision which amended the remedy for the Site to require, in part, the placement of an environmental covenant on the property restricting its use because certain soil and groundwater contamination will remain on the Site. EPA has also requested that the deed restriction OFFICE OF THE CITY ATTORNEY DUBUQUE, IOWA SUITE 330, HARBOR VIEW PLACE, 300 MAIN STREET DUBUQUE, IA 52001-6944 TELEPHONE (563)583-4113/FAX (563)583-1040/EMAIL balesq@cityofdubuque.org be removed from the property, as it is EPA's intent for the environmental covenant to replace the deed restriction as the sole institutional control on the Site. Pursuant to the Amended ROD, the City negotiated this environmental covenant with EPA. At the request of EPA, MidAmerican Energy has also been made a holder of certain rights in the covenant because MidAmerican is conducting the response action at the Site. We have been working with our environmental attorneys, Jane McAllister and Connor Wasson from the Ahlers Firm to develop the covenant. The covenant itself was prepared using the model language provided by the Iowa Department of Natural Resources and Activity and Use Limitations required for the Site by EPA. The Activity and Use Limitations both restrict the City's ability to use the property and require certain affirmative obligations on the part of the City, including, for example, some of the following: giving access to EPA when requested, notifying future users of the property of the contamination and the restrictions, not digging below a certain depth on the property without EPA's permission, not using the property for residential use, and notifying EPA if anyone does work on the property that could disturb the contamination. The practical impacts of the covenant for the City are twofold: (1) the City must ensure its use of the property complies with the terms of the covenant, and (2) the covenant limits the future use of the property and therefore makes it less attractive to future buyers. The City's plans for the future use of the property are to construct a bus transportation facility with incidental office use. This specific use has already been approved by EPA and would meet with the requirements of the covenant. I recommend that the resolution approving the Environmental Covenant and Termination and Release of Property Restriction be submitted to the City Council for consideration and approval.

The signatories hereto have entered into this Environmental Covenant for the purpose of subjecting the property described below, or a portion thereof, to certain activity and use limitations in accordance with the terms and conditions specified herein. 1. The Property. The City of Dubuque, Iowa, is the sole fee simple title owner of that real property legally described in Exhibit A hereto and incorporated herein, with a local address of 925 Kerper Boulevard in Dubuque, Dubuque County, Iowa (hereinafter "Property"). 2. Background. On April 19, 1989, the U.S. Environmental Protection Agency (hereinafter "EPA" or "Agency"), pursuant to its authority under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"), issued an Administrative Order on Consent to address environmental contamination at a site referred to as the Dubuque Peoples Natural Gas Site ("Site"). Pursuant to that order, the City of Dubuque placed institutional controls ("Deed Restriction") on certain of its real property impacted by the contamination, which instrument was recorded as Instrument No. 4730-91 with the Dubuque County Recorder's office. Subsequently, EPA and various parties agreed to implement a remedy for the Site (removal and remedial actions collectively "Environmental Response Project"). On September 25, 2013, EPA issued an Amendment to the Record of Decision, which amended the remedy for the Site to include, in part, placement of this Environmental Covenant on the Site because certain soil and groundwater contamination remains on the Property. The administrative record for the Environmental Response Project is on file at the offices of the U.S. Environmental Protection Agency, Region VII, 11201 Renner Blvd., Lenexa, Kansas 66219. 3. Reopening. The signatories acknowledge that failure of the activity and use limitations to serve their intended purpose including the prevention of exposure to contamination could result in the Agency reopening its review and regulation of the contaminant condition on the Property as may be allowed by applicable law. 4. Identity of Grantor, Grantee/Holder, and Agency, as each is defined in this Environmental Covenant and as provided in Iowa Code 4 455I: Grantor: City of Dubuque, Iowa, an Iowa Municipal Corporation, is the current owner of the Property and the Grantor of this Environmental Covenant. 2 Grantee/Holder: City of Dubuque, Iowa, an Iowa Municipal Corporation.
