TSCA Chemicals-in-Progress Bulletin Office of Pesticides & Toxic Substances Vol. 2, No. 2 APRIL 1981 This bi-monthly news bulletin is intended to inform all persons concerned with theToxic Subtsances Control Act (TSCA) about recent developments and near-term plans. For further information or to request copies of documents mentioned, write the Industry Assistance Office (IAO), (TS-799) OPTS, U.S.E.P.A., Washington, D.C., 20460 or call toll-free 800-424-9065 or, in Washington, D.C., 554-1404. REGULATORY & REQUIRED ACTIONS PREMANUFACTURE NOTIFICATION (PMN)... SECTION 5 Under Section 5(a)(1) a person who intends to introduce into commerce a chemical substance not on the TSCA Inventory must notify EPA at least 90 days before begin- ning manufacture. This rule applies also to imports. The notice must give the chemical identity, production volume, uses, byproducts, occupational exposure and any health and environmental effects information in the submitter's possession. EPA reviews this notification to determine if the substance might present an unreason- able risk that should be remedied through either an order to develop sufficient information or an imme- diately effective rule. Upon such a determination, EPA issues an order to prohibit manufacture and then ap- plies to the court for an injunction to this effect. This order must be issued 45 days before the notification per- iod ends. The original period may be extended by EPA for up to 90 days for good cause. Absent such an order or immediate rule, the manufacturer may proceed with his plans. EPA publishes in the Federal Register a summary of each PMN shortly after receipt and a report on all current receipts each month. Copies of the revised pro- posed forms for manufacturers, importers and exporters are available from IAO for use by submitters during the interim period (See 44 FR 28564, May 15, 1979 and 44 FR 59764, Oct. 16, 1979). The latest PMN status reports are reproduced below.

Committee members are: Council on Environmental Quality (CEQ), Department of Commerce (DOC), Environmental Protec- tion Agency (EPA), National Cancer Institute (NCI), National Institute of Environmental Health Sciences (NIEHS). National Institute for Occupational Safety & Health (NIOSH), National Science Foundation (NSF) and the Occupational Safety & Health Administration (OSHA). The ITC may list up to 50 chemicals or catego- ries of chemicals for testing and is to consider revising or adding to its list every six months. The EPA Administra- tor must respond within one year to each recommenda- tion by initiating rulemaking under Section 4 or giving the Agency's reasons for not doing so. Both the ITC reports and EPA responses appear in the Federal Register. Date No. of Single Chemicals or Categories On January 9, 1 981, a federal district judge placed EPA on a court-ordered schedule for making decisions con- cerning all the chemicals designated for testing in the first five ITC priority lists. EPA had been sued by the Natural Resources Defense Council for its failure to initiate rulemaking, or to offer an adequate explanation why testing should not be required, within the one-year time limit established in Section 4(e) of TSCA In the ruling, Judge Lawrence W. Pierce, of the South- ern District of New York, ordered EPA to proposed rules or decisions not to test by the end of 1983 for ail chemi- cals listed in the first five ITC reports. This schedule had been submitted to theCourton September 12, 1980and was accepted without charge. On February 13, 1981, EPA filed its first required progress report with the Court. It stated that EPA expects to comply with the 1981 schedule. Action The schedule is listed below.

EPA has recently denied a second request (46 FR 6062) to use CFCs in aerosol sprays generating smoke and fog for theatrical productions. On March 17, 1978, (43 FR 11318) EPA published a rule prohibiting almost all manufacturing, processing and distribution in com- merce of CFCs for aerosol propellant uses that are sub- ject to TSCA. The intent of the rule, which became effective on Octoboer 15, 1978, was to reduce CFC emissions to the atmosphere in an attempt to reduce the health and environmental risk caused by depletion of the ozone layer. However, certain exmpetions based on essential use were written into the rule Prior to issuing , the rule, EPA had considered and denied a request to grant an exemption for inclusion of CFCs in the stage product. EPA determined the use was not essential and a CFC substitute could be found. In the recent petition the distributor of "Fog Juice," which is a mixture of CFC propellant and mineral oil, said no workable substitute for CFCs could be found to produce the desired theatrical effect. In the recent denial EPA said alternative pro- ducts, if not perfect substitutes, do exist. Even without substitutes, the Agency said exemptions would be granted only if the health, environmental and economic impacts of the removal were unacceptable.

OnJanuary26, 1981 (46FR3199), EPA proposed a rule that would require the reporting of quantities of asbes- tos used in various processes, employee exposure and monitoring data, waste disposal and pollution control information, EPA had previously published, on October 17, 1979, an advanced notice of proposed rulemaking (44 FR 60055) as part of a joint coordination of regula- tory activities with the Consumer Product Safety Com- mission. If the proposed rule later becomes a rule, EPA collected information will be used to aid the Agency in deciding the appropriate regulation action under TSCA. For the purposes of this rule and to be consistent with the definitions of TSCA, a manufacturer of asbestos is any person who mines, mills or imports asbestos in bulk or imports a product containing asbestos. A processor of asbestos is any person who makes productsfordistribu- tion in commerce that contain asbestos or any asbestos containing component. To reduce the impact on small businesses, EPA proposed to not require reporting from companies of 10 or fewer employees. Additionally, the proposal would require full reporting from only a repre- sentative sample of the industry in most cases. NOTIFICATION OF EXPORT... SECTION 12(b) Under 12(b) exporters are required to submit a notice for the first annual shipment of a substance to any given country for any chemical substance or mixture subject to final Section 4 testing rules; Section 5(b)(4) risk listing for test data; proposed or final Section 5 and 6 rules; orders issued under Section 5 or any action pending or relief granted under Sections 5 or 7. There is no notice form required, but the notice, sub- mitted by mail to EPA, must include the exporter's name and address, the name of the substance or mixture, the date of export or intended export, the country of import and the section of TSCA under which EPA has taken action. Within five working days, EPA will advise the foreign government of the impending exportation and the U.S. regulatory action taken with respect to the sub- stance or mixture. The Section 12(b) rule as of March 1, 1981 applies to the following chemicals by reason of the stated TSCA actions: F = final rule P = proposed rule CHEMICALS TSCA STATUS SECTION PCBs 6 F CFCs 6 F&P 2,3,7.8-TCDD 6 F Asbestos 6 P N-methanesulfonyl-p- toluene sulfonamide 5(a)(2) P STUDIES & SUPPORT ACTIVITY CHEMICAL ACTIVITIES STATUS REPORT The second edition of EPA's Chemical Activities Status Report is now available. The two-volume report, current to July 1 980, is a compilation of EPA's chemical related activities relating to laws administered by the Agency, including the Clean Air, Clean Water Acts, the Federal Insecticide, Fungicide and Rodenticide Act; the Resource Conservation and Recovery Act; the Safe Drinking Water Act and TSCA. The chemical activities of EPA's Office of Research and Development are included Chemical substances are listed alphabetically and by Chemical Abstract Service Number. There is also a chemical name synonym list. This report includes chemical regulatory activities, ongoing and completed technical assistance information, preregulatory assess- ments, chemical and biological testing and monitoring programs and labeling requirements. Using the status report, a researcher can quickly learn who in EPA regu- lates a chemical and what scientific or technical work has been done on the substance. TSCA STATUS REPORT FOR EXISTING CHEMICALS The latest TSCA status report booklet, Volume 2 Issue 1, listing all existing chemicals of interest to the TSCA program, is now available. In this document the regula- tory assessment status of each chemical is arranged alphabetically by CAS number and there is an index of regulatory assessment status within each TSCA pro- gram. This booklet differs from the Chemical Activities Status Report mentioned elsewhere in this Bulletin, being limited to only TSCA activities, while the Chemical Activities Status Report covers all programs of EPA. Because of its more limited nature, the TSCA status report is more up to date. It also uses different data bases. FIRST REPORT OF THE ITSDC The first report of the Interagency Toxic Substances Data Committee (ITSDC) will be published shortly and IA0 is accepting reservations for the booklet. Under Sections 10 and 25 of TSCA the committee is responsible for Federal chemical information system development and coordination. The ITSDC's goal is to systematize the retrieval of toxicological and other scientific data to aid those people responsible for research, risk analysis and decisionmaking. This first report summarizes the pro- gress to date. EPA APPROVES PCB DISPOSAL UNITS The use of two high-temperature commercial incinera- tors capable of destroying concentrations of PCBs has been approved by EPA. The facilities, the first chemical waste incinerators ever to receive EPA approval, are located in Texas and Arkansas and may be a major step in dealing with one of the most important environmental problems in the United States. Enacted in 1 976, TSCA required EPA to prohibit manu- facture, processing, distribution and use of PCBs and to establish PCB storage and disposal rules. Since then, EPA has ruled that wastes containing over 500 parts per million of PCBs can only be destroyed in high tempera- ture (above 1200°C) incinerators operated under con- trolled conditions. Up to now no incinerators have met 6 ------- these EPA burn standards. EPA has estimated there are more than 20 million pounds of PCB liquids in storage awaiting destruction. In announcing EPA's approval of the commercial incin- erator in Deer Park, Texas and owned by Rollins Envi- ronmental Services, Adlene Harrison, EPA's Region 6 Administrator said on January 23, "After exhaustive testing and careful analysis, I am confident that the facility at Rollins has demonstrated the ability to destroy PCBs safely. The continued storage of millions of pounds of these dangerous chemicals pose an eminent threat to the American people and ourenvironment. It is vital that we remove this material from our midst and destroy it promptly. I am pleased that we can begin to do so, providing safe destruction of PCBs already now being stored and the nearly 750 million pounds still in service which will have to be disposed of in the future." On January 28, Harrison approved a second incinerator at El Dorado, Arkansas, owned by Energy Systems Com- pany. The El Dorado facility is capable of burning liquids and solids. The Deer Park incinerator burns only liquids. Tests on both incinerators in 1979 determined that they destroy more than 99.9999 percent of the PCBs in high- level waste oil. Additional tests were conducted to 1980 to insure that the local environment and public health was not threatened by use of the incinerators. PCBs, in use since 1929, do not decompose easily. Their characteristics of low flammability and low conductivity of electricity have made them popular during the past 50 years for use in fluids and lubricating oils especially in transformers and capacitors. PCBs also were used in varnish, wax, glue, carbonless copy paper, sealants, printing ink and in many other products. Highly stable, PCBs break down slowly and therefore not only persist in the environment years after being discarded but also accumulate in the fatty tissues of humans and animals. In laboratory animals, PCBs have been shown to cause cancer, reproductive failures, gastric disorders and skin lesions. PCBs are suspected of causing cancer in humans. In the 1980 tests at the two incinerators, EPA closely monitored for the presence of toxic byproducts. Tetrachlorodibenzo-p-dioxins and tetrachlorodibenzo- p-furans were detected at extreme low levels, in the range of billionths of parts per gram the Agency said. These tests were conducted so that EPA could estimate the health risk to determine if there was any potential for adverse impact. The intent of the estimate was to find the highest conceivable risk. "It is highly improbable that a significant health risk exists," Harrison said, of the test at the Rollins facility. The worst possible situa- tion she said, "is if someone lived near the Rollins facil- ity and was exposed to the maximum ground level concentration of emissions from PCB incinerators con- tinually for 70 years." Even so, she said, "The chances of any increased cancer would be less than one in 50,000." IAO SLIDE SHOWS The IAO has recently updated and made available, free of charge, four TSCA slide shows. These shows espe- cially directed toward chemical manufacturers, proces- sors and importers, go into detailed explanations of TSCA, TSCA testing, PMN, and 8(e) requirements. 1. TSCA—An Overview of Its Authorities and Major Activities—Recently updated, the 25-minute presen- tation covers major actions to date, reviews impor- tant aspects of the law and how the Act is being implemented. 2. Testing Under TSCA—Highlights how chemicals are selected for TSCA priority testing, how model stand- ards for testing rules are developed, who benefits from testing and current action under Section 4. 3. Section 8(e)—Substantial Risk Notification—A 12- minute explanation of the notification process, de- scribing two types of reports, how a company reporting system could be organized, who is respon- sible for reporting, how to determine which health and environmental effects would be considered sub- stantial risk. 4. Proposed Premanufacture Notification Regulations and Interim Policy Guidelines—A comprehensive 28- minute review of the PMN program, what determines a new chemical substance, use of the Inventory, who must submit PMN forms, how to fill out forms and current action and information. Call the toll free number to reserve one or all of the slide shows. TSCA regional coordinators also have copies of the four shows ready for loan. The regional coordinators are listed elsewhere in this issue of the Bulletin. CHEMICAL INFORMATON RESOURCES HANDBOOK The IAO now has available a new handbook that gives detailed information on more than 85, mostly auto- mated, chemical information systems and how each data base can be reached. The Chemical Information Resources Handbook explains each system's scope, and how access is gained. If available, a sample of each system's search/output is included in the directory plus the latest known cost of using each service. The hand- book can aid in searches on chemical toxicology, envi- ronmental effects, spill resources, disposal methods, ambient air and water concentrations, control technolo- gies and governmental regulations. The IAO has available two March 10, 1981 Federal Register notices on PCBs. Both notices are responses to a recent U.S. Court of Appeals ruling that set aside parts of EPA's PCB rule on classifying of transformers, capacitors and electromagnets as totally enclosed. One of the notices spells out the inspection and maintenance procedures that will be in effect for an 18-month period. The second notice is an advance notice of proposed rulemaking. It discusses the court ruling, EPA's need for more factual information about electrical equipment and asks for comments about the propensity of electrical equipment containing PCBs to leak, the nature of expos- ure to PCBs and the cost of reducing or eliminating PCBs in electrical equipment. EPA set December 7, 1981 as the deadline for comments. Call the toll free number for copies of both March 10, 1981 Federal Register notices. REGIONAL TOXIC SUBSTANCES COORDINATORS Each week, the IAO responds to between 500 and 1,000 telephone calls requesting clarification of TSCA's provi- sions or literature published under the program. In addi- tion, hundreds of letters are received each week. Information about TSCA may also be obtained from the 10 regional offices EPA maintains under the program. Listed below are the names of the regional TSCA Coordi- nators, where their offices are located and the States and areas they serve. They, too, will assist you.
