For further information or to request copies of documents mentioned, write the TSCA Assistance Office (TAO), (TS-799) EPA, Washington, D.C. 20460, or call toll-free 800-424-9065 or, in Washington, D.C., or from outside the continental United States, (202) 554-1404. REGULATORY & REQUIRED ACTIONS TESTING OF CHEMICAL SUBSTANCES AND MIXTURES ... SECTION 4 Section 4 of TSCA gives EPA authority to require manu- facturers or processors of chemicals to test the toxic ef- fects of a designated substance. To require testing EPA must find that the chemical may present an unreasona- ble risk; that there are insufficient data available with which to perform a reasoned risk assessment; and that testing is necessary to generate such data. A test rule may also be based on an EPA finding of substantial pro- duction and exposure to humans or the environment, in addition to findings of insufficient data and need for testing. Under section 4(e) an Interagency Testing Committee (ITC) was established to recommend chemicals to EPA for priority consideration. The ITC can designate up to 50 chemicals or categories of chemicals for testing and EPA must respond within one year by starting rulemak- ing under section 4 or giving reasons for not doing so. EPA Makes Available Data Submissions EPA has received, and made available for public inspec- tion, data submissions on chlorinated paraffins, 2-chlorotoluene and alkyl phthalates. The two catego- ries of chemicals and the one chemical had been previ- ously recommended to EPA for testing by the ITC. In each of the situations after the ITC action, a producer or an association of producers presented EPA with a testing plan. The plans were accepted by EPA in lieu of issuing a section 4 test rule because of EPA's view that this approval would lead to the more expeditious devel- opment of test data for the involved chemicals and the Agency's concerns were met by the testing plans. The EPA notice of the receipt of the new data appears in the March 23, 1983, Federal Register (48 FR 12124). The data on chlorinated paraffins were submitted by the Consortium of Chlorinated Paraffin Manufacturers. Chlorinated paraffins are used primarily as flame retardants and plasticizers. Occidential Chemical Corp. submitted the testing data on 2-chlorotoluene. The sub- stance is used as a solvent for agricultural pesticides and is a general solvent replacement for 1,2-dichlorobenzene. The Chemical Manufacturers As- sociation, through its Phthalate Esters Program Panel, is conducting testing on the phthalate esters and alkyl diesters of 1,2-benzenedicarboxylic acid, which are pri- marily used as plasticizers. Section 4(f) of TSCA requires EPA within 180 days after receipt of test data or other information that indicates a chemical substance or mixture may pose a significant risk of serious or widespread harm to human beings from cancer, gene mutations or birth defects to: a) initi- ate appropriate action under sections 5, 6, or 7 of TSCA or b) publish a notice saying why the risk is not unrea- sonable. The 180-day review may be extended for up to 90 additional days for good cause. EPA Reviewing MDA As announced in a April 27, 1983, Federal Register no- tice (FR 19078), EPA has initiated a 180-day review of 4,4'-methylenedianiline (MDA) and is asking the public to submit all available relevant information about the chemical. An EPA decision on MDA will be published on or about September 12, 1983, unless there is good cause to extend the review. EPA is accelerating review of MDA because laboratory tests by the National Toxicological Program have found the chemical to be carcinogenic in both rats and mice. Based upon EPA's review of the NTP study and its own evaluation of exposure potential, EPA concluded that 1 ------- MDA could pose a significant risk of serious harm to workers manufacturing and processing the chemical. MDA is an intermediate used to make other chemicals and plastics, and is not known to be present, as such, in any consumer products but may be present in industrial products such as coatings and rubber additives. Thus, EPA's concern is limited to the workplace. If the use of this chemical requires regulatory action, EPA intends to work jointly with the Occupational Safety and Health Administration (OSHA) of the Department of Labor. EPA estimates that a total of 230 to 450 million pounds of MDA is produced each year in the United States. The National Institute for Occupational Health and Safety estimates that 2,500 workers may be exposed during MDA's manufacturing and processing. There are cur- rently no mandatory worker exposure standards for MDA. EPA is unsure as to the exact number of present pro- ducers. From public records, the following companies were identified as having produced MDA in the past or as possible present producers or importers. Firm Production Location Allied Chemical Co.

EPA PROPOSES TESTING ON INDUSTRIAL CHEMICALS The U.S. Environmental Protection Agency has pro- posed regulations requiring that several industrial chemicals be tested to determine whether they cause environmental problems or pose a health risk to work- ers and consumers. EPA is proposing the testing on the recommendation of an Interagency Testing Committee, a body of scientists representing eight Federal agencies which was estab- lished by Congress under the Toxic Substances Control Act (TSCA). The chemicals are ethyltoluenes (ET), trimethylbenzenes (TMB), and biphenyl. ET and TMB are components of crude oil, gasolines, pe- troleum products, and industrial and consumer sol- vents. Small quantities of both chemicals are used as industrial intermediates. EPA is proposing to require testing of a petroleum refinery product containing ET and TMB because it has been determined that almost all exposure is to this product rather than to the individual chemicals. Biphenyl is used, in combination with other chemicals, as a dye carrier and heat-transfer fluid and is used to produce alkylated biphenyls. Acting Assistant Administrator for Pesticides and Toxic Substances, Don R. Clay, called the proposed rules "an example of EPA's commitment to take prompt and ap- propriate action on chemicals designated for considera- tion by the Interagency Testing Committee." These chemicals were on the 10th list of chemicals submitted by the ITC to EPA. Lists have been submitted to EPA since 1977, with the Agency meeting a May 10, 1983, deadline for taking action on all chemicals on the list. The Agency is acting under the Toxic Substances Con- trol Act and proposes to require firms making the hy- drocarbon mixture containing ET and TMB and biphenyl to be responsible for conducting the testing. EPA's analysis of industry production and sales data shows that testing costs would have no significant economic effect on the firm. Affected companies are encouraged to cooperate on a single test program for each chemical, thereby splitting the costs. In addition to the test rules, EPA proposed a negotiated test agreement for formamide, used as a chemical inter- mediate and as a solvent in petroleum production, soil stabilization and for porous-tip writing instruments. Al- though there is no current U.S. production of formamide, BASF Wyandotte Corporation imports be- tween one and 11 million pounds of it per year. BASF Wyandotte has agreed to perform the testing which the Agency determined was needed for formamide. EPA's new test rule proposals will appear in the Federal Register. A public meeting on the proposals will be held in Washington, D.C., if requested.

SECTION 5 The final PMN rule (48 FR 21722) says "if EPA does not take action to regulate a substance during the review period, the submitter may manufacture or import the new chemical substance without restriction, as soon as the notice review period expires. The submitter must notify EPA by tetter when manufacture or import be- gins. " Upon receipt, EPA adds the new substance to the TSCA Inventory. EPA Publishes Final PMN Rule A final rule establishing premanufacturing notice requirments (PMN) and review procedures under sec- tion 5 was published in the Federal Register on May 13, 1983 (48 FR 21722). The rule becomes effective July 12, 1983. EPA has been operating the PMN program under an interim policy. To date, the Agency has received more than 2,300 PMNs. PMN submitters are required to use the PMN notice form published with the final rule. The final form only requires information necessary for the initial review of a chemical. If EPA decides it needs more detailed infor- mation, it will request the submitter to provide the in- formation during the review period. If necessary the Agency can also obtain further data under section 5(e)- The final rule also clarifies requirements for submitting test data and other health and environmental effects data. For data that appear in the open scientific litera- ture, the PMN submitter need only give the citation. Eliminated from the final rule was a provision for for- mal supplemental reporting (by the PMN submitter and others) during the notice review period, notification re- quirements for processors of exempt chemical sub- stances, and the requirement that notice submitters Contact their customers for information for the PMN. The final rule also clarifies when a submission is incom- plete and how the submitter is notified of the incompleteness. COMMENCEMENT OF MANUFACTURE NOTICES 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 be- ginning manufacture or import.

SECTION 5fe) When information on a substance is insufficient to per- mit a reasoned evaluation and either the manufacture, processing, distribution in commerce, use or disposal may present an unreasonable risk of injury to health andior the environment or the substance may be pro- duced in large quantitites and may present significant or substantial human exposure to it, the Administrator may issue a proposed order, to take effect on the expi- ration of the notification period applicable to the manu- facturing or processing of such substance to prohibit or limit the manufacture, processing, distribution in com- merce, use, or disposal of such substance or to prohibit or limit any combination of such activities. EPA Issues PMN 5(e) Consent Orders on Eight Chemicals Since January, 1983, EPA has issued four consent or- ders under section 5(e) which cover eight chemicals. Only five orders have been issued in the past 3 1/2 years. EPA expects six to ten section 5(e) orders in the next two months. Within this total of 5(e) orders a fur- ther shift in emphasis should be noted. This change is increased use of a section 5(e) Consent Order to require protective measures where in previous years manufac- turers only stated in the PMN submission that special engineering controls or protective equipment that elim- inated exposure would be recommended. Use of a Consent Order allows those measures to be enforced. Below are the 5(e) orders issued since January 1983: CONSENT ORDER NO. PMN NO. CHEMICAL IDENTIFICATION (0»QENERIC) FR CITATION (DO-DITTO) ORDER DESCRIPTION 6 82-684 G Halogenated hydrocarbon 47 FR 43160 9-30-82 A 5(e) Consent Order was negotiated establishing use of protective equip- ment during portions of manufactur- ing and processing of the chemical. The Order was issued January 17, 1983. 7 ------- 7 83-23 G Substituted phenol 47 FR 46371 10-18-82 A 5(e) Consent Order of March 9, 1983 requires use of dermal protection for all of the substances, and positive pressure, full facepiece air-supplied respirators for two of the chemicals, pending information sufficient to as- sess the risks posed.

It also bans domestic manufacture. REPORTING RULES SECTION 8(a) Under section 8(a) EPA may require manufacturers and processors to submit information on named chemicals of the following types: production, use, occupational exposure and environmental release. Summary Of 8(a) Preliminary Aseesment Information Amendment* • Final amendment permitting all chemicals and mix- tures designated by the Interagency Testing Commit- tee (ITC) for testing consideration to be made subject to the rule without separate proposal and comment- Published May 11. 1983 (48 FR 21294). • Final amendment requiring reporting by manufactur- ers of remaining chemicals designated by the ITC on its Sixth through ninth reports—Published May 19, 1983 (48 FR 22694). • Proposed amendment requiring reporting on chemi- cals recommended by the ITC in its Eleventh Report- Published May 19,1983 (48 FR 22697). • Amendment (automatic final) requiring reporting on chemicals designated by the ITC in its Twelfth Re- port—to be published in June, 1983. • Rule Related Notice announcing the Agency's intent to release aggregate statistics from information sub- mitted under the section 8(a) Preliminary Assessment Information Rule and the section 8(a) Asbestos Rule— to be published in June, 19B3. EPA Proposes Reporting of Information on Chlorinated Ter phenyl On April 29, 1983, EPA published a rule (48 FR 19419), under section 8(a) that would require manufacturers or importers to report to EPA certain information on any existing or proposed production of chlorinated terphenyl. Persons who want to comment on this pro- posal should submit written comments no later than June 28, 1983, that bear the document number OPTS-82007. they should be sent to the TSCA Publica- tion Information Officer, EPA, TS-793, Rm. E-108, Wash- ington DC 20460. The Interagency Testing Committee (ITC) designated the category of polychlorinated terphenyls for testing consideration in April 1978 (43 FR 16684). Chlorinated terphenyl is a member of this category and is the only member of this category on the TSCA Chemical Sub- stance Inventory. Other members of the category are subject to Premanufacture Notification under section 5 of TSCA. The ITC recommended that polychlorinated terphenyls be tested for carcinogenicity, mutagenicity, 8 ------- teratogenicity, other chronic health effects, and for en- vironmental effects. Because domestic production and importation of chlorinated terphenyl apparently have ceased, EPA concluded that the section 4 testing recom- mended by the ITC is not warranted, (see EPA's re- sponse to the ITC 46 FR 54482), and that a section 8(a) rule can alert the Agency of any resumption of manu- facture of importation. If EPA is notified of chlorinated terphenyl manufacture or import, the Agency will re- consider the need for action to require testing under section 4 of TSCA or for control of the reported activity. SIGNIFICANT NEW USE ... SECTION 9(a)(2) Under section 5(a)(2) EPA determines when certain uses of chemical substances are significant new users. A determination is made by a significant new use rule (SNUR) promulgated after considering all relevant fac- tors. The factors include the projected volume of manu- facturing and processing of the substance, the extent to which the substance's new use changes the type and form of exposure to humans or the environment, the extent to which the substance's use increases the mag- nitude and duration of exposure to humans of the envi- ronment, and the anticipated manner and methods of manufacturing, processing, distributing in commerce an disposal of the substance. Under section 5(a)(1)(B), persons must notify EPA at least 90 days before manu- facturing, processing or importing a chemical sub- stance for a significant new use as determined by EPA. In addition, persons who intend to export, for any pur- pose, a substance that is subject to a proposed SNUR must notify EPA under section 12(b). EPA Proposed Chlorinated Naphthalene* SNUR EPA is proposing a Significant New Use Rule (SNUR) under TSCA section 5(a)(2) for a category of existing chemicals known as chlorinated napthalenes. Under this proposed SNUR, any domestic manufacture of chlorinated napthalenes and any import over 100,000 pounds a year are considered "significant new uses" subject to SNUR reporting. The proposed rule was pub- lished on Friday May 6, 1983, (48 FR 20668). Persons who want to comment on this proposal should submit written comments no later than July 5, 1983, that bear the document number OPTS 60502. They should be sent to the TSCA Publication Information Officer, EPA, TS-793, Rm. E-108, Washington DC 20460. EPA has serious health and environmental concerns about chlorinated napthalenes. The Agency is primarily concerned about the potential for oncogenicity in hu- man exposed to the substances. In addition, EPA is con- cerned about chlorinated napththalenes' potential for other health effects, as well as potential ecological haz- ar 8 re8u'ting from release of the substances. ~ 9J8Lth# ,nt#rafl«ncy Testing Committee (ITC) desig- th* "tegory of substances known as chlorinated napthalenes for priority consideration for a test rule un- der section 4 of TSCA. The ITC recommended that the following tests be conducted for chlorinated napthalenes: mutagenicity, teratogenicity, long-term carcinogenicity, environmental effects tests, and chron- ic studies to evaluate the other effects of prolonged ex- posure. However, because the use of chlorinated napthalenes had declined sharply (34,000 pounds imported in 1981) and because domestic menufacture of the substances had ceased, EPA announced that it would not propose a section 4 test rule, instead, the Agency requested comments on regulatory alternatives. After evaluating the comments, EPA decided to propose a SNUR so that the Agency can assess risk resulting from a significant change or increase in human or envi- ronmental exposure to chlorinated napthalenes before the exposure occurs. HEALTH AND SAFETY RULE ... SECTION 8(d) Section 8(d) authorizes EPA to promulgate rules on specifically listed chemicals and categories of chemi- cals that would require manufacturers and processors to submit lists and copies of health and safety studies that they have conducted or were initiated by them. EPA Adds Substances To 8(d) List Eleven chemicals and three categories of chemicals have been added to the list of substances and mixtures for which lists and copies of unpublished health and safety studies must be submitted to EPA under the sec- tion 8(d) health and safety data rule. The substances were named in a March 30, 1983 Federal Register notice (48 FR 13178). On September 2, 1982, EPA published (47 FR 38780) a fi- nal rule requiring chemical manufacturers and processors to provide the Agency with unpublished health and safety information on specific chemicals. In that notice EPA listed chemicals and categories that be- came subject to the rule's requirements. EPA will use the studies to aid its investigation of the risks posed by chemicals and to help it determine whether to require industry to test chemicals under section 4. The following chemical and categories of chemicals designated mixtures are subject to the section 8(d) rule. Benzyl butyl phthalate, 85-68-7 Biphenyl, 92-52-4 Butyl gylcolyl butyl phthalate, 85-70-1 Chlorendic acid, 115-28-6 4-Chlorobenzotrifluoride, 98-56-6 2-Chlorotoluene, 95-49-8 Diethylenetriamine, 111-40-0 Ethyltoluenes This category consists of ethyltoluene (mixed iso- mers) and the ortho-, meta- and para-isomers.

Any subatences fitting the category definition Added to the TSCA Inven- tory after March 30, 1983, are also subject to this subpart. 9 ------- Tetrafluoroethene, 116-14-3 Trifluoroethene, 359-11-5 Hexafluoropropene, 116-15-4 Trifluoromethylethene, 677-21-4 Formamide 75-12-7 Hexachloroethane 67-72-1 Phenylenediamines This category is defined as all nitrogen-unsubstituted phenylenediamines and their salts with zero to two substituents on the ring selected from the same or different members of the group of halo, nitro, hyroxy, hydroxy-lower alkoxy, lower-alkyl, and lower alkoxy. For this purpose, the term "lower" is defined as a group containing between one and four carbons. As of March 30, 983, this category includes, but is not limited to, the following phenylenediamines and any category members reported as confidential for the TSCA Inventory. Any substances fitting the category definition added to the TSCA Inventory after March 30, 1983, are also subject to this subpart.

SECTION 8 (•) Under section 8(e) persons who obtain new information which reasonably supports the conclusion that a sub- stance presents substantial risk of injury to human health or the environment must notify EPA within 15 days. These notices are then reviewed by OTS and an initial evaluation is prepared containing, if appropriate, followup questions to the submitter, referrals to other agencies, and recommended OTSIEPA followup actions. The 8(e) notices represent a company's first review of a situation and a judgment in compliance with the statute to submit a notice within IS days of obtaining the infor- mation. EPA publishes its evaluations of these notices to make this section 8(el information widely available and understandable to a broad public. The submissions and the initial evaluations are located in the OPTS Pub- lic Reading Room, first floor. East Tower, Waterside Mall, 401 M Street, SW, Washington, D.C.

SUPPORT ACTIVITY EPA To Make Public A Status Report On Existing Ch*mioala The OTS is now issuing a quarterly report, and is mak- ing it available, on the status of various existing chemi- cals that are being reviewed for possible action under TSCA. OTS also plans to inform the public about up- coming Chemical Hazard Information Profiles (CHIPs) so that there can be more public input into the TSCA ex- isting chemicals program. A CHIP itself is a brief sum- mary of readily available information concerning the health and environmental effects and potential expo- sure of a chemical. When new CHIPs are produced the Chemicals-in-Progress Bulletin will inform the public, (see related story "EPA Requests Information For CHIPs") Both the January-March 1983 quarterly report on the status of existing chemicals and a list of existing CHIPs are available through the TAO. The TAO also has two previously offered papers that explain the TSCA ex- iting chemicals program. In early 1982, EPA produced Priorities for OTS Operations" and in November 1982 issued a supplement "Existing Chemicals Program" which describes the process for evaluation of existing chemicals. EPA Raquaats Information For CHIPs OTS is requesting information from the public on chem- icals chosen for Chemical Hazard Information Profiles (CHIPS). Because the literature search for a CHIP is gen- erally limited to automated data bases and reference works, OTS encouragas interested parties to submit un- published, recently published and other hard-to-obtain studies on the chemical(s) of interest. Relevant studies include those which pertain to health effects, environ- mental effects, commercial production and uses, ex- posed populations, environmental levels, and any other information relevant to an assessment of the chemical's impact on human health or the environment. OTS is also interested in any current testing or assessment ac- tivities being conducted by other organizations. When a chemical is selected for CHIP preparation, the TSCA Assistance Office (TAO) will notify by letter the organizations and individuals on a mailing list, now be- ing compiled. To be most helpful, information on chem- icals chosen for CHIPs should be received within 6 weeks of the TAO letter. Persons who want to be includ- ed on the CHIP mailing list should call the Toll Free number at: 800-424-9065 (in the Washington, D.C. area please call 554-1404). Written request should be sent to the TSCA Assistance Office (TS-799), EPA, 401 M St. S.W. Washington, D.C. 20460. When naw CHIP selections are produced they will be listed in the Chemicals-in-Progress Bulletin. CHIPS recently started dimethyl methyl phosphonate (756-79-6) proprionitrile (107-12-0) ziram (137-30-4) All responses with information on these CHIP chemicals should be sent to: Document Control Officer, Management Support Division (TS-793), Office of Toxic Substances, 401 M Street, S.W., Washington, D.C. 20460, ATTN: T. O'Bryan To be considered in the development of these CHIPs, in- formation should be received by June 30, 1983. All information submitted in response to the solicita- tions will be placed in a public file and made available for public inspection unless the submitter asserts a claim of confidentiality in accordance with the provi- sions of section 14 of TSCA. EPA will handle all confidentiality claims in accordance with its procedures governing the confidentially of business information (40 CFR Part 2, Subpart B). Persons may inspect non- confidential submissions when in Washington, D.C. at EPA (401 M St. S.W., Room E-107 from 8:00 a.m. to 4:00 p.m. Monday-Friday. OTS encourages comment on the accuracy and thoroughness of information pre- sented in the CHIP in an effort to broaden the distribu- tion of completed CHIPs.

The volume covers the February 1, 1980, to De- cember 31, 1982 period. All three volumes contain status reports prepared by the Office of Toxic Substances (OTS) for initial section 8(e) submissions received by EPA from chemical manu- facturers, processors and distributors. EPA publishes the volumes of status reports to make the reported in- formation more accessible. Specific examples of sub- mitted information and EPA's evaluation of it are in- cluded in these reports. OTS believes that persons subject to section 8(e) will be better able to understand the types of information that should be submitted by referring to these volumes. A limited supply of volume 3 is available through the TSCA Assistance Office (toll-free: 800-424-9065 or in Washington, D.C.: 554-1404) or write to: TSCA Assist- ance Office (TS-799), U.S. Environmental Protection Agency, 401 M St., S.W., Washington, D.C. 20460. Once this supply is exhausted copies will be available through the National Technical Information Service (NTIS). EPA's supply of the first two volumes in the series is ex- hausted, but may be purchased from NTIS at 5285 Port Royal Rd., Springfield, VA 22161. The NTIS order desk number is (703) 487-4650. The NTIS numbers for the first two volumes are PB 80-221609 and PB 81-145732. Clay Named Acting Assistant Administrator for OPTS Don R. Clay, a career civil servant, has been named Act- ing Assistant Administrator for Pesticides and Toxic Sub- stances. He replaces Dr. John A. Todhunter, who re- signed on March 25, 1983. Clay, from August 1981, until named to his new assign- ment, was Director of the Office of Toxic Substances. Prior to that he managed the engineering sciences pro- gram of the U.S. Consumer Product Safety Commis- sion. From 1972 to 1974 he was Deputy Assistant Com- missioner for Planning and Evaluation at the U.S. Food and Drug Administration. Marcia Williams has been named acting director of the Office of Toxic Substances. Ms. Williams served as dep- uty director to Mr. Clay since February 1982 and was formerly with the Office of Pesticides Programs. TSCA Report to Congress is Available The TSCA report to Congress for fiscal year 1982 is now available. The report summarizes progress made by EPA in implementing the Act during the fiscal year, which ended on September 30, 1982. After the limited supply is exhausted, the report may be purchased from the National Technical Information Service (NTIS). Industry Assistance Office Named Changed To TSCA Assistance Office The Industry Assistance Office's name has officially changed to the TSCA Assistance Office (TAO). The new office name reflects broadened responsibilities of the office to provide assistance not only to the regulated community but also to other interested citizens as well as the international community interested in the imple- mentation activities under TSCA. New Asbestos-in-Buildlngs Guidance Document Available The Office of Toxic Substances recently published a new document called "Guidance For Controlling Friable Asbestos-Containing Materials in Buildings." The pur- pose of the report is to supplement previous EPA guid- ance by emphasizing recent experience and new infor- mation on asbestos abatement and control. The guidance may be helpful to school officials and building owners who are considering 1 rripi¥m#fwngrW«H'#«tOs control program. The 154-page document wilt also be helpful to building owners who must establish priorities for asbestos abatement and control. The TSCA Assistance Office is now taking orders for the report. Because of the expected demand for the book, EPA will limit the number of copies sent to any one location. The report is also available from EPA regional offices. When the supply is exhausted, the report will be available for purchase through the National Technical Information Service.
