Superfund The sites at which O&R has been asserted to have liability under Superfund include its manufactured gas sites, its West Nyack site and other Superfund sites discussed below.
There may be additional sites as to which assertions will be made that O&R has liability.
For a further discussion of claims and possible claims against O&R under Superfund, see Note G to the financial statements in Item 8 (which information is incorporated herein by reference).
Manufactured Gas Sites.
O&R and its predecessors formerly owned and operated manufactured gas plants at seven sites (O&R MGP Sites) in Orange County and Rockland County, New York.
Four of these sites are now owned by parties other than O&R, three of which have been redeveloped by them for residential, commercial or industrial uses.
The DEC is requiring O&R to develop and implement remediation programs for the O&R MGP Sites.
O&R has completed remedial investigations at five of its seven MGP Sites and will complete investigation of the remaining two sites in 2006.
O&R has completed the remediation at one of its sites and has received DEC’s decision regarding the remedial work to be done at another site.
Since the latter site is Companyowned and has no off-site impacts, remediation of this site has been deferred, with DEC’s concurrence, until approximately 2010.
O&R is currently implementing remediation at its Nyack MGP site.
West Nyack Site.
In 1994 and 1997, O&R entered into consent orders with the DEC pursuant to which O&R agreed to conduct a remedial investigation and remediate certain property it owns in West Nyack, New York at which PCBs were discovered.
Petroleum contamination related to a leaking underground storage tank was found as well.
O&R has completed all remediation at the site that the DEC has required to date.
The DEC has requested an additional groundwater investigation and an on-site vapor intrusion study.
Other Superfund Sites.
O&R is a PRP with respect to other Superfund sites where there are other PRPs and it is not managing the site investigation and remediation.
Work at these sites is in various stages, with the company participating in PRP groups at some of the sites.
Investigation, remediation and monitoring at some of these sites has been, and is expected to continue to be, conducted over extended periods of time.
The company does not believe that it is reasonably likely that monetary sanctions, such as penalties, will be imposed upon it by any governmental authority with respect to these sites.
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (COMBINED FOR CON EDISON AND CON EDISON OF NEW YORK)–CONTINUED O&R’s electric sales and deliveries, excluding off-system sales, in 2005 compared with 2004 were:
## Table 1 ##
Electric sales and delivery volumes in O&R’s service area in 2005 increased 6.8 percent compared with 2004 due primarily to the warmer summer weather, growth in the number of customers, and the unbilled revenue adjustment referenced above.
Absent this adjustment and after adjusting for weather variations in each period, electric delivery volumes in O&R’s service area increased 2.3 percent in 2005.
O&R’s purchased power costs increased $74 million in 2005 compared with 2004 due to an increase in the average unit cost and higher delivery volumes.
Electric operating income increased by $7 million in 2005 compared with 2004 due primarily to higher net revenues ($23 million), offset by higher operations and maintenance expenses ($3 million) and income taxes ($12 million).
Gas O&R’s gas operating revenues increased $24 million in 2005 compared with 2004.
The increase is due primarily to higher costs of gas purchased for resale in 2005.
O&R’s revenues from gas sales are subject to a weather normalization clause that moderates, but does not eliminate, the effect of weather-related changes on net income.
O&R’s gas sales and deliveries, excluding off-system sales, in 2005 compared with 2004 were:
## Table 2 ##
Sales and transportation volumes for firm customers decreased 2.2 percent in 2005 compared with 2004 reflecting the impact of the milder winter weather.
After adjusting for weather variations in each period, total firm sales and transportation volumes were 0.7 percent higher for 2005 than in 2004.
Non-firm transportation of customer-owned gas to electric generating plants increased substantially in 2005 compared with 2004 due to higher demand for generation related to the warmer than normal summer.
The increase in gas usage had minimal impact on earnings because most revenues from these customers result from a fixed demand charge for local transportation.
Gas operating income was the same in 2005 as in 2004.

September 2007, the NYSDEC demanded that the company investigate and remediate PCB contamination that may have migrated into the adjacent Flushing River from the site.
In April 2008, the company and NYSDEC entered into a consent order under which the company has agreed to implement a NYSDECapproved investigation program for the Flushing River and, if deemed necessary by the NYSDEC to protect human health and the environment from such contamination, to implement a NYSDEC-approved remediation program for any PCB contamination in the river attributable to the site.
At this time, the company cannot estimate its liability for the investigation and cleanup of any PCB contamination that may have migrated to the Flushing River from the site, but such liability may be substantial.
Gowanus Canal In August 2009, CECONY received a notice of potential liability and request for information from the EPA about the operations of the company and its predecessors at sites adjacent or near the 1.8 mile Gowanus Canal in Brooklyn, New York.
The company understands that the EPA also has provided or will provide notices of potential liability and information requests to other parties.
The EPA has proposed adding the Gowanus Canal to its National Priorities List of Superfund sites.
The canal’s adjacent waterfront is primarily commercial and industrial, currently consisting of concrete plants, warehouses, and parking lots, and the canal is near several residential neighborhoods.
The company expects that the cost of assessment and remediation of hazardous substances in and around the Gowanus Canal will be substantial.
CECONY is unable to predict its exposure to liability with respect to the Gowanus Canal site.
Other Superfund Sites CECONY is a potentially responsible party (PRP) with respect to other Superfund sites where there are other PRPs and where it is generally not responsible for managing the site investigation and remediation.
Work at these sites is in various stages, with the company participating in PRP groups at some of the sites.
Investigation, remediation and monitoring at some of these sites have been, and are expected to continue to be, conducted over extended periods of time.
The company does not believe that it is reasonably likely that monetary sanctions, such as penalties, will be imposed upon it by any governmental authority with respect to these sites.
The following table lists each of CECONY’s other Superfund sites for which the company anticipates it may have a liability.
The table also shows for each such site, its location, the year in which the company was designated or alleged to be a PRP or to otherwise have responsibilities with respect to the site (shown in the table under “Start”), the name of the court or agency in which proceedings with respect to the site are pending and its estimated percentage of total liability for each site.
The company currently estimates that its potential liability for investigation, remediation, monitoring and environmental damages at each site is less than $200,000, with the exception of the Cortese Landfill site, for which the estimate is $1.2 million.
Superfund liability is joint and several.
The company’s estimate of its liability for each site was determined pursuant to consent decrees, settlement agreements or otherwise and in light of the financial condition of other PRPs.
The company’s actual liability could differ substantially from amounts estimated.
## Table 4 ##
O&R Superfund The sites at which O&R has been asserted to have liability under Superfund include its manufactured gas sites, its West Nyack site, the Newark Bay site, and other Superfund sites discussed below.
There may be additional sites as to which assertions will be made that O&R has liability.
For a further discussion of claims and possible claims against O&R under Superfund, see Note G to the financial statements in Item 8 (which information is incorporated herein by reference).
Manufactured Gas Sites O&R and its predecessors formerly owned and operated manufactured gas plants at seven sites (O&R MGP Sites) in Orange County and Rockland County, New York.
Three of these sites are now owned by parties other than O&R, and have been redeveloped by them for residential, commercial or industrial uses.
The NYSDEC is requiring O&R to develop and implement remediation programs for the O&R MGP Sites including any neighboring areas to which contamination may have migrated.
Through the end of 2009, O&R has conducted remedial investigations at all seven O&R MGP Sites and completed investigation of six of these sites.
Supplemental investigation activities are ongoing at one of the former MGP sites.
O&R has completed the remediation at one of its sites; has completed the NYSDEC-approved remediation program for the land portion of its Nyack site; and has received NYSDEC’s decision regarding the remedial work to be done at two other sites.
Remedial design will begin in 2010 for two of the sites.
Feasibility studies will be completed in 2010 for the two remaining sites and the shoreline/ sediment portion of the Nyack site.
