ATLANTA - August 26, 2013 - On August 21, 2013, AGL Resources Inc. (NYSE: GAS) received unanimous approval from the New Jersey Board of Public Utilities (BPU) to implement its Accelerated Infrastructure Replacement (AIR) program. The BPU approved a stipulated agreement previously reached between AGL Resources' Elizabethtown Gas utility and the BPU Staff that will enable the company to invest up to $115 million over a four-year period to enhance the safety, reliability and integrity of the Elizabethtown Gas distribution system. The program is consistent with the New Jersey Energy Master Plan, which supports investments in natural gas infrastructure as a means of reducing energy costs and enhancing energy security.

Under the terms of the agreement, Elizabethtown Gas will file a rate case no later than September 1, 2016, at which time the AIR program costs will be subject to review. During the term of the AIR program, Elizabethtown Gas will accrue AFUDC (Allowance for Funds Used During Construction) related to project expenditures during the construction period, and accrue associated carrying costs from the time the project is placed in service until the time its costs are recovered through base rates.

The New Jersey infrastructure program approval comes just two weeks following the approval of another significant AGL Resources' infrastructure enhancement program, the integrated vintage plastic replacement program (i-VPR) under Atlanta Gas Light Company in Georgia.

Atlanta Gas Light's vintage plastic pipe replacement program, which was approved unanimously by the Georgia Public Service Commission (PSC) on August 6, 2013, is a program to replace more than 750 miles of vintage plastic pipe within the utility's natural gas distribution system. The program authorizes a phased-in approach to funding the four-year, $275 million system investment through the company's existing STRIDE (Strategic Infrastructure Development and Enhancement) program.

Atlanta Gas Light has more than 3,300 miles of vintage plastic pipe within its approximate 33,000-mile gas distribution system. Referred to in the industry as vintage plastic, this classification of pipe was manufactured with certain resins susceptible to premature degradation depending on service conditions. At the time of installation, the industry projected a useful life of between 60 and 70 years.  Like most gas utilities across the country, Atlanta Gas Light installed vintage plastic pipe between 1965 and 1984. These plastic pipes are used for medium and low-pressure applications while protected steel pipe is reserved for high-pressure use.

The construction program initially will be funded through a surcharge on customer bills of $0.48 through December 2014. Additional surcharges of $0.48 and $0.49 will be applied in January 2015 and January 2016, respectively, and will continue through 2025.

Later this year, Atlanta Gas Light will complete its 15-year pipeline replacement program, which has resulted in the company replacing more than 2,700 miles of aging bare steel and cast iron pipe. Also, this fall the PSC is expected to consider the second phase of two existing infrastructure programs that are part of STRIDE. The 10-year system reinforcement program and the related customer growth program approved in 2009 focus on pressure improvements to better serve peak day demand, and on economic development expansions to high-growth areas served by the Atlanta Gas Light system.  The second phase of these programs proposes to invest up to $260 million over a four-year period.

"Our recently approved infrastructure investment programs in Georgia and New Jersey are vital to maintaining and enhancing the overall reliability, safety and integrity of our distribution systems in those service areas," said John W. Somerhalder, chairman, president and chief executive officer of AGL Resources. "We also have a similar program at Virginia Natural Gas, which was approved by the Virginia State Corporation Commission in 2012. With new legislation recently passed in Illinois, we anticipate making a significant investment in infrastructure enhancement at our largest utility, Nicor Gas, in the near future."

The new legislation in Illinois, signed into law by Illinois Gov. Pat Quinn in July, will enable modernization of natural gas infrastructure in the state and provide a surcharge mechanism for utilities to recover the cost of their investments in system reliability.

Under the legislation, Nicor Gas could invest up to $150 million annually, over a nine-year period beginning in 2015, to upgrade certain portions of its distribution system. The program governing these investments is subject to review and approval by the Illinois Commerce Commission (ICC).  The company expects to make a proposal to the ICC in 2014.

"We are fortunate to operate in states where our regulators and legislators recognize the importance of these critical infrastructure programs and support their implementation in a way that minimizes the overall impact on customer bills and enables the company to recover its costs in a timely manner," said Hank Linginfelter, executive vice president of utility operations for AGL Resources. "We have demonstrated a strong track record of prudent capital investment in our distribution systems to ensure their reliability and safety. These recent positive developments support our ability to continue making those investments to better serve our customers for many years to come."
