Manufactured Gas Plants. Because of recent environmental concerns, AGLC is required to investigate possible environmental contamination at manufactured gas plants ("MGP") and, if necessary, clean up any contamination. AGLC has been associated with ten MGP sites in Georgia and three in Florida. Based on investigations to date, AGLC believes that some cleanup is likely at most of the sites. As reported in Holdings Quarterly Report on Form 10-Q for the quarter ended June 30, 2002 (the "June 30, 2002 10-Q"), the remaining costs of future actions at these sites will be approximately $143.1 million, some of which costs are recoverable by Holdings. For a further description of this matter, see "Item 2. Management's Discussion and Analysis of Results of Operations and Financial Condition - Environmental Matters" in the June 30, 2002 10-Q.
Manufactured Gas Plants. Georgia. Atlanta Gas Light Company (“AGLC”) is required to investigate possible environmental contamination at manufactured gas plants (I) and, if necessary, clean up any contamination. AGLC has been associated with ten MGP sites in Georgia and three in Florida. Based on investigations to date, cleanup has either already occurred or is likely at most of these sites. As of June 30, 2006, the remediation program in Georgia was approximately 100% complete, with the exception of ground water conditions. As reported in Holdings Quarterly Report on Form 10-Q for the quarter ended June 30, 2006, the projected costs of the remaining remediation at these sites are estimated to be $25 million, with additional future costs for the Florida sites in the range of $7 million to $11 million.
Manufactured Gas Plants. In the past, Indiana Gas, SIGECO, and others operated facilities for the manufacture of gas. Given the availability of natural gas transported by pipelines, these facilities have not been operated for many years. Under currently applicable environmental laws and regulations, Indiana Gas, SIGECO, and others may now be required to take remedial action if certain byproducts are found above the regulatory thresholds at these sites. Indiana Gas has identified the existence, location, and certain general characteristics of 26 gas manufacturing and storage sites for which it may have some remedial responsibility. Indiana Gas has completed a remedial investigation/feasibility study (RI/FS) at one of the sites under an agreed order between Indiana Gas and the IDEM, and a Record of Decision was issued by the IDEM in January 2000. Although Indiana Gas has not begun an RI/FS at additional sites, Indiana Gas has submitted several of the sites to the IDEM's Voluntary Remediation Program (VRP) and is currently conducting some level of remedial activities, including groundwater monitoring at certain sites, where deemed appropriate, and will continue remedial activities at the sites as appropriate and necessary.

Manufactured Gas Plants. We have a program to investigate and perform necessary remediation at our fifty-three sites where gas was manufactured in the past (Manufactured Gas Plants, or MGPs). Eight sites are included in the New York State Registry; three sites are included in the New York State Department of Environmental Conservation Multi-Site Order on Consent; three sites are part of Maine’s Voluntary Response Action Program with two such sites part of Maine’s Uncontrolled Sites Program. The remaining sites are not included in any registry list. We have entered into consent orders with various environmental agencies to investigate and, where necessary, remediate forty-one of the fifty-three sites. Our estimate for all costs related to investigation and remediation of the fifty-three sites ranges from$ 168 million to $423 million as of September 30, 2019. Our estimate could change materially based on facts and circumstances derived from site investigations, changes in required remedial actions, changes in technology relating to remedial alternatives and changes to current laws and regulations. Certain of our Connecticut and Massachusetts regulated gas companies own or have previously owned properties where MGPs had historically operated. MGP operations have led to contamination of soil and groundwater with petroleum hydrocarbons, benzene and metals, among other things, at these properties, the regulation and cleanup of which is regulated by the federal Resource Conservation and Recovery Act as well as other federal and state statutes and regulations. Each of the companies has or had an ownership interest in one or more such properties contaminated as a result of MGP-related activities. Under the existing regulations, the cleanup of such sites requires state and at times, federal, regulators’ involvement and approval before cleanup can commence. In certain cases, such contamination has been evaluated, characterized and remediated. In other cases, the sites have been evaluated and characterized, but not yet remediated. Finally, at some of these sites, the scope of the contamination has not yet been fully characterized; no liability was recorded related to these sites as of September 30, 2019 and no amount of loss, if any, can be reasonably estimated at this time. In the past, the companies have received approval for the recovery of MGP-related remediation expenses from customers through rates and will seek recovery in rates for ongoing MGP-related remediation expenses for all of t...
