- iv - <br /> identifies PACs,as noted in the Summary of Codes. Chemicals belonging to these categories are <br /> reportable under section 313 by category, rather than by individual chemical name. <br /> Ammonium Salts. The EPCRA section listing for ammonia includes the following qualifier <br /> "includes anhydrous ammonia and aqueous ammonia from water dissociable ammonium salts and <br /> other sources; 10 percent of total aqueous ammonia is reportable under this listing." The qualifier for <br /> ammonia means that anhydrous forms of ammonia are 100% reportable and aqueous forms are limited <br /> to 10% of total aqueous ammonia. Therefore,when determining threshold and releases and other waste <br /> management quantities all anhydrous ammonia is included but only 10% of total aqueous ammonia is <br /> included. Any evaporation of ammonia from aqueous ammonia solutions is considered anhydrous <br /> ammonia and should be included in threshold determinations and release and other waste management <br /> calculations. <br /> In this document ammonium salts are not specifically identified as being reportable EPCRA <br /> section 313 chemicals. However,water dissociable ammonia salts, such as ammonium chloride, are <br /> reportable if they are placed in water. When ammonium salts are placed in water,reportable aqueous <br /> ammonia is manufactured. As indicated in the ammonia qualifier, all aqueous ammonia solutions from <br /> water dissociable ammonium salts are covered by the ammonia listing. For example, ammonium <br /> chloride is a water dissociable ammonium salt and reportable aqueous ammonia will be manufactured <br /> when it is placed in water. <br /> Unlike other ammonium salts, ammonium hydroxide is specifically identified as being a <br /> reportable EPCRA section 313 chemical. This is because the chemical ammonium hydroxide <br /> (NH40H) is a misnomer. It is a common name used to describe a solution of ammonia in water(i.e., <br /> aqueous ammonia), typically a concentrated solution of 28 to 30 percent ammonia. EPA has <br /> consistently responded to questions regarding the reportability of these purported ammonium <br /> hydroxide solutions under the EPCRA section 313 ammonia listing by stating that these are 28 to 30 <br /> percent solutions of ammonia in water and that the solutions are reportable under the EPCRA section <br /> 313 ammonia listing. For a more detailed discussion, see page 341.75 of the Federal Register final rule <br /> of June 30, 1995 (60 FR 34172).
