Subpart U – Miscellaneous Uses of Carbonate
This page provides resources for subpart U reporters, including implementation information as well as supporting documents for relevant rulemakings.
On this page:
Summary
This source category consists of any facility that is covered by the rule and that uses any form of carbonate (CO32-) in a manufacturing process that emits carbon dioxide (CO2). Carbonates covered by this rule include limestone (CaCO₃), dolomite (CaMg(CO3)2), ankerite (Ca(Fe,Mg,Mn)(CO3)2), magnesite (MgCO3), siderite (Fe++CO3), rhodochrosite (MnCO3), and sodium carbonate (Na2CO3). Facilities are considered to emit CO2 if they consume at least 2,000 short tons (tons) per year of CO32- heated to a temperature sufficient to allow the calcination reaction to occur.
This subpart does not cover the use of CO32- for producing cement, ferroalloys, glass, iron (Fe) and steel, lead (Pb), lime, phosphoric acid (H3PO4), pulp and paper, soda ash, sodium bicarbonate (NaHCO3), sodium hydroxide (NaOH), and zinc (Zn), because these processes are covered by other parts of this rule.
