USTs

United States Treasuries (USTs) are debt securities issued by the U.S. Department of the Treasury to fund government spending. They include multiple maturities: Treasury Bills (short-term, up to one year), Treasury Notes (2 to 10 years), Treasury Bonds (longer than 10 years), and Inflation-Protected Securities (TIPS). T-Bills are issued at a discount and mature at par, while notes, bonds, and TIPS pay semiannual interest. USTs are widely regarded as among the safest investments because they are backed by the government’s credit. They are actively traded in primary and secondary markets, and yields reflect current rates. Interest on USTs is subject to federal taxes but generally exempt from state and local taxes.

Underground Storage Tanks (USTs) are containers for storing liquids such as petroleum products or hazardous substances beneath the ground. In the United States, they are regulated to prevent leaks that could contaminate soil and groundwater. Regulatory requirements include spill and overfill prevention, corrosion protection, leak detection, and proper closure or upgrading of older tanks. Owners must demonstrate financial responsibility for cleanup, and releases trigger investigation and remediation. The UST program is administered by the Environmental Protection Agency and state agencies, with standards that have evolved since the 1980s to reduce leaks and improve tank integrity.
