Municipal Utility Natural Gas Supply Act of 2001

Municipal Utility Natural Gas Supply Act of 2001 - Amends the Internal Revenue Code to exclude from the definition of the term "investment property," as such term is used in defining "higher yield investments," any prepayment on a supply contract for the purpose of obtaining a supply of natural gas reasonably expected to be used by a utility which is owned and operated by a State or local government, or any State or local government political subdivision or instrumentality (thus permitting municipal gas systems to use their tax-exempt borrowing authority to fund the purchase of long-term, prepaid supplies of natural gas).
