        99.1    November 30, 2010 BMO Capital Markets 6th Annual Pipeline and Utility Day Investor Presentation

This report contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.  Forward-looking statements are based on management’s beliefs and assumptions.  These forward-looking statements, which address the Company’s expected business and financial performance, among other matters, are identified by terms and phrases such as:  anticipate, believe, intend, estimate, expect, continue, should, could, may, plan, project, predict, will, potential, forecast and similar expressions.  Forward-looking statements involve risks and uncertainties that may or could cause actual results to be materially different from the results predicted.  Factors that could cause actual results to differ materially from those indicated in any forward-looking statement include, but are not limited to: changes in demand for natural gas or NGL and related services by customers, in the composition of the Company’s customer base and in the sources of natural gas or NGL available to the Company; the effects of inflation and the timing and extent of changes in the prices and overall demand for and availability of natural gas or NGL as well as electricity, oil, coal and other commodities, bulk materials and chemicals; adverse weather conditions, such as warmer or colder than normal weather in the Company’s service territories, as applicable, and the operational impact of natural disasters; changes in laws or regulations, third-party relations and approvals, and decisions of courts, regulators and/or governmental bodies affecting or involving the Company, including deregulation initiatives and the impact of rate and tariff proceedings before FERC and various state regulatory commissions; the speed and degree to which additional competition, including competition from alternative forms of energy, is introduced to the Company’s business and the resulting effect on revenues; the impact and outcome of pending and future litigation and/or regulatory investigations, proceedings or inquiries; the ability to comply with or to successfully challenge existing and/or or new environmental, safety and other laws and regulations; unanticipated environmental liabilities; the uncertainty of estimates, including accruals and costs of environmental remediation; the impact of potential impairment charges; exposure to highly competitive commodity businesses and the effectiveness of the Company's hedging program; the ability to acquire new businesses and assets and integrate those operations into its existing operations, as well as its ability to expand its existing businesses and facilities; the timely receipt of required approvals by applicable governmental entities for the construction and operation of pipelines and other projects; the ability to complete expansion projects on time and on budget; the ability to control costs successfully and achieve operating efficiencies, including the purchase and implementation of new technologies for achieving such efficiencies; the impact of factors affecting operations such as maintenance or repairs, environmental incidents, natural gas pipeline system constraints and relations with labor unions representing bargaining-unit employees; the performance of contractual obligations by customers, service providers and contractors; exposure to customer concentrations with a significant portion of revenues realized from a relatively small number of customers and any credit risks associated with the financial position of those customers; changes in the ratings of the Company’s debt securities; the risk of a prolonged slow-down in growth or decline in the United States economy or the risk of delay in growth or decline in the United States economy, including liquidity risks in United States credit markets; the impact of unsold pipeline capacity being greater than expected; changes in interest rates and other general market and economic conditions, and in the Company’s ability to continue to access its revolving credit facility and to obtain additional financing on acceptable terms, whether in the capital markets or otherwise; declines in the market prices of equity and debt securities and resulting funding requirements for defined benefit pension plans and other postretirement benefit plans; acts of nature, sabotage, terrorism or other similar acts that cause damage to the Company’s facilities or  the Company’s  suppliers' or customers' facilities; market risks beyond the Company’s control affecting its risk management activities including market liquidity, commodity price volatility and counterparty creditworthiness; the availability/cost of insurance coverage and the ability to collect under existing insurance policies; the risk that material weaknesses or significant deficiencies in internal controls over financial reporting could emerge or that minor problems could become significant; changes in accounting rules, regulations and pronouncements that impact the measurement of  results of operations, the timing of when such measurements are to be made and recorded, and the disclosures surrounding these activities; the effects of changes in governmental policies and regulatory actions, including changes with respect to income and other taxes, environmental compliance, climate change initiatives and authorized rates of recovery of costs (including pipeline relocation costs); and other risks and unforeseen events, including other financial, operational and legal risks and uncertainties detailed from time to time in filings with the SEC.

These factors are not necessarily all of the important factors that could cause actual results to differ materially from those expressed in any of the Company’s forward-looking statements.  Other factors could also have material adverse effects on the Company’s future results.  These and other risks are described in greater detail in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009, its Quarterly Reports on Form 10-Q and its other reports filed with the Securities and Exchange Commission.  In light of these risks, uncertainties and assumptions, the events described in forward-looking statements might not occur or might occur to a different extent or at a different time than the Company has described.  The Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required by law.
