Title: Impacts of TSCA on SRC-II commercialization. [Toxic substances control act; impact]

Abstract

The Toxic Substances Control Act of 1976 (TSCA) is one set of environmental legislation that might constrain the commercialization of coal conversion plants. This paper examines the potential impacts of TSCA on coal conversion using the Solvent-Refined Coal (SRC-II) process of coal liqudfaction as representative of emerging conversion technologies. The key element in any assessment of the impact of TSCA on the SRC-II coal liquefaction process is an assessment of the potential hazard to human health and the environment posed by the SRC-II products and by-products. Our analysis shows that many SRC-II products and by-products may be considered hazardous in that they are reported to contain appreciable amounts of naphthalenes, phenanthrenes, alkyl benezenes, and other aromatic hydrocarbon compounds. Table E-I illustrates some of the possible constraints that the implementation of TSCA might impose on the commercialization of SRC-II or other coal liquefaction processes. Although the table indicates that TSCA may place many constraints on the SRC-II process, these constraints will probably not pose a substantial hindrance to commercialization prospects. Detailed studies must be conducted to determine the actual economic impacts of TSCA implementation before an accurate assessment of the ultimate impact on SRC-II commercialization can be determined.

  • The PMN Number to EPA Accession Number Link Diskette provides a cross-reference of these numbers for commenced PMNs on the confidential portion of the TSCA Master Inventory File. Neither this cross-reference nor the additional information included is TSCA Confidential Business Information. Provided on the diskette for each confidential commenced PMN are the PMN Case Number, EPA Accession Number, Generic Name, and EPA special flags. The sequence of the file is in ascending PMN case Number order with `P` case numbers sorted first, followed by `Y` case numbers.

  • The 1990 Supplement to EPA's 1985 Edition of the Toxic Substances Control Act (TSCA) Chemical Substance Inventory covers approximately 5,000 substances that have been added to the Inventory since the 1985 publication. However, substances that were added to the Inventory after February 1, 1990 are not included in the publication. Together, the 1985 Edition and the 1990 Supplement constitute a revised Inventory representing a total of 68,000 chemical substances. From a regulatory standpoint, the Inventory defines what chemical substances are existing in U.S. commerce for purposes of implementing TSCA. Substances that are not included on the Inventory are considered newmore » by EPA and are subject to the Premanufacture Notification (PMN) requirements under Section 5(a) of TSCA.« less

  • In 1990, a technical evaluation of the TSCA Ambient Air Monitoring Program was conducted. It can be concluded that the present sapling system does not meet the overall program objective. The lower boundary limit or detection limit of the system prevents detection of the TCDD, 2378-TCDD and 2378-TCDF at Action Level 1 concentrations; the retention efficiency studies and breakthrough volume calculations show significant losses in hexachlorobenzene and PCBs; and the upper boundary limit or saturation air concentration of the system prevents detection of Action Level 2 and 3 concentrations of PCBs and hexachlorobenzene. Action Level 1 is a concentration levelmore » distinctly above background levels and signals the beginning of a possible trend toward rising pollutant concentrations.'' No adverse health effects are expected to accompany exposures at this level. Action Level 2 is a concentration level one-tenth the level of an acute significant exposure level required to produce the earliest signs of toxicity. Action Level 3 represents an exposure level associated with the likely development of adverse health effects. Two design modifications are recommended. First, it is recommended that the present system be modified to incorporate EPA's recent ambient air sampling protocol for semivolatiles. EPA recommends that a dual sorbent vapor trap, XAD-2 resin sandwiched between two polyurethane foam adsorbents, be used. This dual sorbent trap has been found to prevent breakthrough of PCBs and should also prevent breakthrough of hexachlorobenzene. Secondly, a proposed sampling train that will detect TCDD at Action Level 1 would include thermal desorption of an appropriate adsorbent directly into a Gas Chromatography/High Resolution Mass Spectrometer after collection.« less

  • The computer tape contains the Inventory Synonym Name File and the Inventory Preferred Name File of the Toxic Substances Control Act (TSCA) Toxic Substance Inventory. These files reflect the 61,277 substances on the non-confidential Inventory file as of January 1, 1993. The EPA N flag, which indicates a polymeric substance containing no free-radical initiator in its Inventory name, but is considered to cover the designated polymer made with any free-radical initiator regardless of the amount used, appears on these tapes for the appropriate polymers that were included in the 1990 Supplement. The tapes do not include this flag for polymersmore » that were listed in the 1985 Edition. A review of the statistics for the amounts of CBI and non-CBI records on the source file and the file that produced these tapes, as well as the types of data elements selected, confirms that no TSCA CBI data are on the tapes.« less
