Thank you, Senator Vitter. These provision are very important to many major domestic producers including manufacturers of products like glass, steel, cement, along with domestic energy producers across the country. The chemical nomenclature provision in section 8 of the compromise addresses several issues critical to the efficient functioning of the new chemical regulatory framework. For the purposes of the TSCA Inventory, a single, defined molecule is simple to name. For example, ethanol is a Class 1 chemical on the TSCA Inventory. Its identity does not depend on how it is made. Since one ethanol is chemically the same as another ethanol, a new producer of ethanol can use the existing ethanol chemical listed on the TSCA Inventory. For other substances known as Class 2 chemicals, nomenclature is more complex. For those substances, the name of the substance typically includes either--or both--The source material and the process used to make it. The compromise requires EPA to maintain the Class 2 nomenclature system, as well as certain nomenclature conventions in widespread use since the early days of TSCA. The compromise also directs EPA to continue to recognize the individual members of categories of chemical substances as being on the TSCA inventory. The individual members of these categories are defined in inventory descriptions developed by EPA.…
