Maximizing the resources we use

From power poles and transformer oil to office waste and scrubber byproducts, Exelon is continually improving its materials management by identifying less hazardous and/or better-performing products and reducing waste.

Across Exelon’s businesses, we are working to better understand our total waste generation and ensure that the best management practices are in place to reduce internal resource use. In addition to excellent recycling operations, we place an equally strong focus on identifying waste reduction opportunities that prevent waste before it is created.

Greening Our Operations

As part of our business and environmental strategy, we are committed to “Greening our Operations” in order to minimize the impact we have on the environment.


Exelon Recycling

We improved our waste accounting systems to ensure that we capture all waste activities and maximize recycling.

More information about Exelon's waste management programs can be found under the Reducing Waste section in Exelon Corporation's 2012 Sustinability Report (PDF, 3MB) . 


Coal Combustion Product Reuse

At the facilities we operate, Exelon aims to manage the by-products associated with coal-fired electricity generation responsibly and actively seeks opportunities for reuse. These by-products include both ash and synthetic gypsum from air pollution control equipment. These efforts help minimize disposal costs while preserving natural resources and avoiding the use of valuable landfill space. Exelon Power’s beneficial reuse programs at our wholly-owned or direct assets have historically far outpaced the national recycling rate of approximately 45% for these types of materials.



Managing Legacy Environmental Issues

Exelon proactively seeks to understand and manage the sensitive environmental conditions in which it operates. We maintain a system for tracking and managing these risks and regularly assess performance to drive continuous improvement.

For more detailed discussion of Exelon’s remediation activities, please see Part I, Item 1 “Environmental Regulation” section of  Exelon’s 2011 Form 10-K.

PCB Elimination

Exelon continues to eliminate equipment at its power plants and substations determined to contain PCBs greater than 50 parts per million during repair and servicing efforts. These reduction efforts, combined with voluntary retrofill/reclassification programs, are resulting in the continued reduction of PCB-containing equipment across Exelon. BGE has been working to voluntarily and proactively target unknown distribution transformers and remove them if they are likely to be contaminated. Exelon Nuclear removed its last PCB transformer during 2012.

Manufactured Gas Plants

ComEd, PECO and BGE continue to remediate former manufactured gas plant sites that were used — primarily by predecessor companies in Pennsylvania, Illinois and Maryland between 1850 and the 1950s — to manufacture gas for lighting and other purposes. ComEd, PECO and BGE anticipate that the majority of remediation at remaining sites will continue for several more years.


Compliance Performance

Exelon has set a goal of zero land related Notices of Violation (NOV) and Permit Non-compliances for company operations.

NOVs are issued by regulatory agencies when a company is believed to have violated a permit condition or regulatory requirement. Exelon self-reports violations of regulations and regulatory agency-specified environmental permit conditions when they are identified.
