### 40 CFR Parts 712and 716 [OPTS-82035; FRL-3773-3] Preliminary Assessment Information and Health and Safety Data Reporting; Addition ofChemicals AGENCY: Environmental Protection 

### Agency (EPA). ACTION: Final rule. SUMMARY: The 

### Interagency Testing Committee (ITC)in its Twenty-sixth Report to EPA recommended thatEPA give priority consideration to one chemical substance and three categories ofchemical substances in proposing test rules to assist EPA in determining which, ifany, tests are needed for the substance and categories. EPA is adding 

### the substance and categories to two model information-gathering rules: The Toxic Substances Control Act (TSCA) section 8(a) Preliminary Assessment 

### Information Rule (PAIR) and the TSCA section 8(d) Health and Safety Data 

### Reporting Rule. These model rules will require manufacturers, importers, and processors ofthe specific substances 

### and members ofthe categories toreport production, use, exposure-related, and unpublished health and safety data to EPA.

This rule adds one substance and three categories ofsubstances (with 76 individual substances identified) to the PAIR and the same substance and categories (with 64 individual substances identified) to the 8(d) Health and Safety Data Reporting Rule. Several ofthe substances in the categories recommended by the ITCare already listed on either the PAIR, the section 8(d) Health and Safety Data Reporting Rule, or the Comprehensive Assessment Information Rule (CAIR), and have not been included in this rule. EFFECTIVE DATE: This rule 

### will become effective on October 29, 1990. FOR FURTHER INFORMATION CONTACT.

### (202) 554-0551. SUPPLEMENTARY INFORMATION: This 

### rule adds one substance and three categories ofsubstances to the PAIR and the section 8(d) Health and Safety Data Reporting Rule and adds a new section 

### j 716.120(d) for listing category members. Manufacturers, processors, and importers ofthese chemicals will be required to report unpublished health 

### and safety data and/or end use, exposure, and production volume data to EPA. I.Background I Section 4(e) ofTSCA established the ITC and authorized it to recommend to EPA chemical substances and mixtures (chemicals) to be given priority consideration in proposing testrules under section 4. For some ofthese chemicals, the ITCmay designate that EPA must respond to its recommendations within 12 months. In this time, EPA must either initiate a rulemaking to test the chemical or publish in the Federal Register its reasons for not doing so.

On May 8, 1990, EPA announced the receipt ofthe Twenty-sixth Report of the ITC (55FR 23050). The Twenty-sixth Report revises and updates the Committee's priority list ofchemicals and adds 1chemical substance and 3 categories containing 79 substances to the section 4(e) priority list.This rule adds the chemical substance and the three categories ofsubstances to the PAIR and to the section 8(d) Health and Safety Data Reporting Rule. These two rules are model information gathering rules which assistEPA in responding to the ITCrecommendations.

EPA issued the PAIR under section 8(a) ofTSCA (15U.S.C. 2007(a)), and it is codified at 40 CFR part 712. This model section 8(a) rule establishes standard reporting requirements for manufacturers and importers ofthe chemicals listed in the rule at 40 CFR 712.30. These manufacturers and importers are required to submit a onetime report on general volume, end use, and exposure-related information using the Preliminary Assessment Information Manufacturer's Report (EPA Form 7710- 35). EPA uses this model section 8(a) rule to gather current information on chemicals ofconcern quickly.

EPA issued the model Health and Safety Data Reporting Rule under section 8(d) ofTSCA (15 U.S.C. 2607(d)), and it is codified at40 CFR part 718. The section 8(d) model rule requires past, current, and prospective manufacturers, importers, and processors oflisted chemicals to submit to EPA copies and lists ofunpublished health and safety studies on the listed chemicals that they manufacture, import, orprocess. These studies provide EPA with useful. information and have provided significant support forEPA's decisionmaking under TSCA sections 4. 5, 6.8, and 9.

These model rules provide for the automatic addition ofITCpriority list chemicals. Whenever EPA announces the receipt ofan ITCreport, EPA may, at the same time without further notice and comment, amend the two model information-gathering rules by adding the recommended chemicals. The amendment adding these chemicals to the PAIR and the Health and Safety Data Reporting Rule becomes effective 30 days after publication. U.Chemicals To Be Added

In its Twenty-sixth Report toEPA, the ITCrecommended for priority consideration one substance and three categories ofsubstances with a total of 79 substances identified inthe three categories.

### Several ofthe chemical substances in the categories recommended by the 

### ITC are already listed in thePAIR, the section 8(d) Health and Safety Data Reporting Rule, orthe CAIR.As discussed below, these substances are excluded from the amendments to the PAIR and section 8(d) rules being promulgated today. (Note that the chemical names on the ITC Priority List arethe common names while the names used in this rule are from the TSCA Chemical Substance Inventory.)

Fifteen ofthe substances are already listed In the section 8(d) Health and Safety Data Reporting Rule: Phosphoric acid, tributyl ester (CAS No. 126-73-8) was added on May 19, 1986 (51 FR 18323), and the remaining 14 were added on May 1,1987 (52 FR 16022). The Agency will not add these substances to the section 8(d) Health and Safety Data Rule at this time,because these substances are already listed and subject to a 10-year reporting period.

In addition, three chemical substances fromthe Isocyanates group were added to CAIR on December 22,1988 (53 FR 246): 2,6-toluene diisocyanate (CAS No. 91-08-7), 2,4-toluene diisocyanate (CAS No. 584-84-9) and toluene diisocyanate (CAS No. 26471-62-5). Since the CAIR asks questions which are similar to some ofthe PAIR questions, EPAhas decided not to require PAIR reporting forthese three substances. However, if the information received under the CAIR isnot sufficient, the Agency reserves the right to require the PAIR reporting at a later time. (Note that these 3 substances are also 3ofthe 15 substances not being added to the section 8(d) Health and Safety Data listas noted above.)

Phenyl isocyanate (CAS No. 103-71- 9), ethene bromo- (CAS No. 593-60-2) and phosphoric acid, and tributyl ester (CAS No. 126-73-8) were each previously placed on the 8(a) PAIR list (Phenyl isocyanate and ethene bromoin 1982 (47 FR 26992) and phosphoric acid in 1988 (51 FR 18323)). However, EPAneeds updated information on these substances, and therefore has included these substances in today's rule. M.Reporting Requirements A. Preliminary AssessmentInformation Rule

All persons who manufactured or imported the chemical substances named in this rule during their latest complete corporate fiscal year must submit a Preliminary Assessment Information Manufacturer's Report (EPA Form No. 7710-35) for each manufacturing orimporting site atwhich they manufactured or imported a named chemical substance. A separate form must be completed foreach chemical substance and submitted to the Agency no later than December 27,1990. Persons who have previously and voluntarily submitted a Manufacturer's Report to. the ITC orEPA may be able to submit a copy ofthe original Report to EPA orto notify EPAby letter oftheir desire to have thisvoluntary submission accepted in lieu ofa current data submission.See 

### I 712.30(a)(3). '

Details ofthe reporting requirements, the basis for exemptions, and a facsimile ofthe reporting form, are provided in 40CFR part 712. Copies of the form are available from the TSCA Environmental Assistance Division at the address listed under FOR FuRTHER INFORMATION CONTACT. 

### B.HealthandSafetyDataReporting Rule

Listed below are the general reporting requirements ofthe section 8(d) model rule.

1.Persons who, in the 10 years preceding the date a substance is listed, either have proposed to manufacture, import, or process, orhave manufactured, imported, orprocessed, the listed substance must submit to EPA: A copy ofeach health and safety study which is in their possession at the time the substance is listed.

2.Persons who, at the time the substance is listed, propose to manufacture, import, or process; or are manufacturing, importing, orprocessing 

### the listed substance must submit to EPA:

a.A copy ofeach health and safety study which is in their possession at the time the substance is listed.

b.A list ofhealth and safety studies known to them but not in their possession at the time the substance is listed.

c.A list ofhealth and safety studies that are ongoing at the time the substance is listed and are being conducted by orforthem.

d.A list ofeach health and safety study that is initiated after the date the substance is listed and is conducted by or for them.

e. A copy ofeach health and safety study that was previously listed as ongoing or subsequently initiated and is now complete-regardless ofcompletion date

3. Persons who, after the time the substance is listed, propose to manufacture, import, or process the listed substance must submit to EPA:

a. A copy ofeach health and safety study which Is in their possession at the time they propose to manufacture, import, or process the listed substance.

b.A list ofhealth and safety studies known to them but not intheir possession at the time they propose to manufacture, import, or process the listed substance. 

### 39781

### Federal Register / Vol. 55, No. 189 / Friday, September 28, 1990 / Rules and Regulations

c.A list ofhealth and safety studies that are ongoing at the time they propose to manufacture, import, or process the listed substance, and is being conducted by orfor them.

d. A list ofeach health and safety study that is initiated after the time they propose to manufacture, import, or process the listed substance, and is conducted by orfor them.

a. A copy ofeach health and safety study that was previously listed as ongoing or subsequently initiated and is now complete-regardless ofthe completion date.

The bulk ofreporting is required at the time the substance is listed. Persons described in categories 1 and 2 do all or most oftheir health and safety data reporting at the start of the reporting period. The remaining reporting requirements, specifically categories 2(d), 2(e), and 3, continue prospectively.

Detailed guidance forreporting unpublished health and safety data is provided inthe Federal Register of September 15, 1986 (51 FR 32720). Also found there are the reporting exemptions. C.Submissionof PAIRReports and Section8(d) Studies

PAIR reports and section 8(d) health and safety studies must be sent to: TSCA Document Processing Center (TS790), Office ofToxic Substances, Environmental Protection Agency, 401 M St., SW.,Washington, DC20460, ATIN: (insert eitherPAIR or8(d) Reporting). D.Removal ofChemicals from theRules Any person who believes that section 8(a) or8(d) reporting required by this rule is unwarranted, should promptly submit to EPA in detail the reasons for thatbelief. EPA, in its discretion, may remove the substance fromthis rule for good cause (40CFR 712.30 and 716.105). When withdrawing a substance from the rule, EPA will issue a rule amendment for publication in the Federal Register. IV. Release of Aggregate Data

EPA will follow procedures for the release ofaggregate statistics as prescribed in the Federal Register notice ofJune 13, 1983 (48FR 27041). Included in the notice are procedures for requesting exemptions from the release ofaggregate data.Exemption requests concerning the release ofaggregate data on any chemical substance must be received by EPA no later than December 27,1990. V. Economic Analysis A. Preliminary AssessmentInformation Rule

EPA estimates the PAIR reporting cost ofthis rule is $178,898. To calculate this figure, EPAused information from the 1986TSCA Inventory Update and SRI Directory ofChemical Producers to generate a list ofmanufacturers and importers ofthis one substance and three categories listing 78 substances. None ofthe companies identified qualify as a small business as defined in40 CFR 712.25(c), thus, EPA expects 83 firms to generate a total of143 reports. Reporting costs (dollars)

### B.HealthandSafetyDataReporting Rule

EPA estimates the total reporting costs for establishing section 8(d) reporting requirements for one substance and three categories listing 64 substances to be $210,922.This cost estimate Ishigh because EPA is uncertain about the likely number of respondents to the rule. Although EPA has used the best available data to make its economic projections, much of the information is basedupon the 1986 TSCA Inventory Update and secondary information from industry sources. Therefore, EPA tends to overestimate rather than underestimate reporting burden.

Nevertheless, the cost ofthis final rule is low in comparison with the potential public health and environmental problems posed by these chemicals. Therefore, EPA isjustified in obtaining data to determine better whether further regulatory action would benecessary.

Under Executive Order 12291, EPA mustjudge whether a regulation is "major" and, therefore, subject to the requirement of a Regulatory Impact Analysis. This rule is not major because it will not result in an effect on the economy of$100 million or more, an increase in costs or prices, or any of the adverse effects described in the Executive Order.

This amendment was not submitted to the Office ofManagement and Budget (OMB) for review, because the automatic listing ofsubstances recommended by the ITC is provided for in40 CFR 712.30(c) and 716.18(b).
