# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Direct final rule.

# SUMMARY:

                        This direct final rule the removes chemical substances phosphorotrithious acid, tributyl ester, CAS No. 150-50-5, and phosphorodithioic acid, O,O-diethyl ester, sodium salt, CAS No. 3338-24-7, which were inadvertently added to the list of  voluntary High Production Volume (HPV) Challenge Program orphan (unsponsored) chemical substances by EPA. As a result, these chemical substances were inadvertently added to two final rules: The Preliminary Assessment Information Reporting (PAIR) rule (Toxic Substances Control Act (TSCA) section 8(a)) and the Health and Safety Data Reporting rule (TSCA section 8(d)), both published in the                         **Federal Register**                         issue of August 16, 2006.  With this removal action, persons who manufacture (including import) either of these two chemical substances are no longer subject to the reporting requirements imposed by these TSCA section 8(a) and 8(d) rules.                    

# DATES:

This rule is effective on June 29, 2007 without further notice, unless EPA receives adverse comment on or before May 30, 2007.

## II. Background

### A. What Action is the Agency Taking?

                    The chemical substances phosphorotrithious acid, tributyl ester, CAS No. 150-50-5, and phosphorodithioic acid, O,O-diethyl ester, sodium salt, CAS No. 3338-24-7, are being removed from the table in 40 CFR 712.30(e) of the TSCA section 8(a) PAIR rule published in the                     **Federal Register**                     of August 16, 2006 (Ref. 1), and the table in 40 CFR 716.120(d) of the TSCA section 8(d) Health and Safety Data Reporting rule published in the                     **Federal Register**                     of August 16, 2006 (Ref. 2). On August 16, 2006, EPA published a final PAIR rule under TSCA section 8(a) (40 CFR part 712), which requires manufacturers (including importers) of chemical substances in the category of voluntary HPV Challenge Program orphan (unsponsored) chemical substances on the ITC's TSCA section 4(e)                     *Priority Testing List*                     to submit a one-time report on general production/importation volume, end use, and exposure-related information to EPA.  Also on August 16, 2006, EPA published a final Health and Safety Data Reporting rule under TSCA section 8(d) (40 CFR part 716), which requires manufacturers (including importers) of chemical substances in this category of voluntary HPV Challenge Program orphan (unsponsored) chemical substances to submit certain unpublished health and safety data to EPA.  On September 15, 2006, EPA published a final rule (Ref. 3) that revised the effective date of the two rules published on August 16, 2006. The effect of this action is that persons who manufacture (including import) either of the two chemical substances are not  subject to the reporting requirements imposed by the final TSCA section 8(a) and 8(d) rules published on August 16, 2006, and the rule published on September 15, 2006 (Ref. 3), that changed the effective date for these two rules.                

### B. What is the Agency's Authority for Taking This Action?

EPA promulgated the PAIR rule under TSCA section 8(a) (15 U.S.C. 2607(a)), and it is codified at 40 CFR part 712.  This model TSCA section 8(a) rule establishes standard reporting requirements for certain manufacturers (including importers) of the chemical substances listed in the rule at 40 CFR 712.30. The final rule published by EPA on August 16, 2006, amended the model TSCA section 8(a) rule by adding the ITC category of certain voluntary HPV Challenge Program orphan (unsponsored) chemical substances (Ref. 1).

EPA promulgated the model Health and Safety Data Reporting rule under TSCA section 8(d) (15 U.S.C. 2607(d)), and it is codified at 40 CFR part 716. The TSCA section 8(d) model rule requires past, current, and prospective manufacturers, importers, and (if specified by EPA in a particular notice or rule under TSCA section 8(d)) processors of listed chemical substances to submit to EPA copies and lists of unpublished health and safety studies on the listed chemical substances that they manufacture, import, or (if specified by EPA in a particular notice or rule under TSCA section 8(d)) process. The final rule published by EPA on August 16, 2006, amended the model TSCA section 8(d) rule by adding the ITC category of certain voluntary HPV Challenge Program orphan (unsponsored) chemical substances (Ref. 2).

### C. Why is EPA Using a Direct Final Rule?

                    EPA is publishing this direct final rule without a prior proposed rule because we view this as a non-controversial action and anticipate no adverse comment.  If EPA receives adverse comment, we will publish a timely withdrawal in the                     **Federal Register**                     informing the public that the direct final rule will not take effect.  Any parties interested in commenting must do so on or before May 30, 2007.                

### D. Why are These Two Chemical Substances Being Removed?

                    The chemical substances phosphorotrithious acid, tributyl ester, CAS No. 150-50-5, and phosphorodithioic acid, O,O-diethyl ester, sodium salt, CAS No. 3338-24-7, were inadvertently added by EPA to the list of HPV orphan orphan (unsponsored) chemical substances.  This list was the source of the category of “Voluntary HPV Challenge Program orphan (unsponsored) chemicals” that was the subject of the TSCA section 8(a) PAIR rule and TSCA section 8(d) Health and Safety Data Reporting rule published in the                     **Federal Register**                     of August 16, 2006 (Refs. 1 and 2).  These two chemicals were originally sponsored in the HPV Challenge Program by Bayer CropScience on March 15, 1999 (Ref. 4).  Subsequently, in a letter dated December 29, 2003, Bayer CropScience requested that EPA “designate the two chemicals as ‘no longer HPV’ on the HPV Challenge Program Chemical List” because Bayer CropScience considered the chemicals to be “non-isolated intermediates” (Ref. 5).  In a letter dated December 3, 2004, EPA responded that, based on a review of the information submitted by Bayer CropScience, EPA had determined that the two substances were “isolated intermediates” and, consequently, did not meet the ‘no longer HPV’ criteria and that “they will remain in the HPV Challenge Program and should continue to be reported” (Ref. 6).  In a letter dated December 15, 2005, Bayer CropScience clarified the status of the two chemicals (Ref. 7).  In that letter, Bayer “recommit[ed] to sponsoring” both chemicals in the HPV Challenge Program and proposed to include the two chemicals into two categories.  This record demonstrates that Bayer CropScience did not withdraw its commitment to sponsor these two chemicals in the HPV Challenge Program.  Consequently, EPA is removing these two chemicals from the table in 40 CFR 712.30(e) of the TSCA section 8(a) PAIR rule published in the                     **Federal Register**                     of August 16, 2006 (Ref. 1), and the table in 40 CFR 716.120(d) of the TSCA section 8(d) Health and Safety Data Reporting rule published in the                     **Federal Register**                     of August 16, 2006 (Ref. 2).                

This action does not preclude the future listing of these two chemical substances under the TSCA section 8(a) PAIR rule or the TSCA section 8(d) Health and Safety Data Reporting rule should the information be reasonably required.

## III.  Economic Analysis

In the economic analysis conducted for the final TSCA section 8(a) PAIR rule, the Agency estimated the total reporting cost to industry to be $644,000 for all 243 chemical substances, or approximately $2,650 per chemical substance (Ref. 1).  The Agency is estimated to incur an additional $248,000 or $1,021 per chemical substance to provide public support for the TSCA section 8(a) PAIR rule and to process the data (Ref. 1).  The total cost of the TSCA section 8(a) rule, per chemical substance, is estimated to be approximately $3,671.  This direct final rule removes two chemical substances from the TSCA section 8(a) PAIR rule.  Therefore, costs are estimated to be reduced by $7,342 (two chemical substances x $3,671 per chemical substance).

                    Furthermore, this direct final rule will also remove two chemical substances                           ( print page 21122)                        from the TSCA section 8(d) Health and Safety Data Reporting rule.  The economic analysis conducted for the TSCA section 8(d) Health and Safety Data Reporting rule estimates that the total cost to industry is $110,000 and to the Agency is $79,000, or $453 and $325 per chemical substance, respectively, for a total of $778 per chemical substance (Ref. 2).  Because this direct final rule  removes two chemical substances from the TSCA section 8(d) Health and Safety Data Reporting rule, the costs of the TSCA section 8(d) Health and Safety Data Reporting rule are estimated to be reduced by $1,556 (two chemical substances x $778).                

Therefore, the removal of two chemical substances from the TSCA section 8(a) and TSCA section 8(d) rules is estimated to result in a total reduction in costs of $8,898.

## V. Statutory and Executive Order Reviews

### A. Executive Order 12866: Regulatory Planning and Review

                    The Office of Management and Budget (OMB) has exempted actions under TSCA sections 8(a) and 8(d) related to the PAIR and Health and Safety Data Reporting rules from the requirements of Executive Order 12866, entitled                     *Regulatory Planning and Review*                     (58 FR 51735, October 4, 1993).  In addition, this direct final rule does not impose any new requirements and will result in a burden and cost reduction; therefore, it is not subject to OMB review under the Executive order.                

### B. Paperwork Reduction Act

                    The information collection requirements contained in TSCA sections 8(a) PAIR and 8(d) Health and Safety Data Reporting rules have already been approved by OMB under the provisions of the Paperwork Reduction Act (PRA), 44 U.S.C. 3501*et seq*., and OMB control numbers 2070-0054 (EPA ICR No. 0586) and 2070-0004 (EPA ICR No. 0575).  The collection activities in this direct final rule are captured by the existing approval and do not require additional review and/or approval by OMB.                

### C. Regulatory Flexibility Act

                    Because this direct final rule eliminates reporting requirements, the Agency certifies pursuant to section 605(b) of the Regulatory Flexibility Act (RFA), 5 U.S.C. 601*et seq*., that this action will not have a significant adverse economic impact on a substantial number of small entities.                

### D. Unfunded Mandates Reform Act

Pursuant to Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public Law 104-4, EPA has determined that this direct final rule does not contain a Federal mandate that may result in expenditures of $100 million or more for State, local, and tribal governments, in the aggregate, or the private sector in any 1 year. In addition, EPA has determined that this direct final rule will not significantly or uniquely affect small governments. Accordingly, the direct final rule is not subject to the requirements of UMRA sections 202, 203, 204, or 205.

### E. Executive Order 13132: Federalism

                    This direct final rule has no Federalism implications because it will not have substantial direct effects on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled                     *Federalism*                     (64 FR 43255, August 10, 1999).                

### F.  Executive Order 13175: Consultation and Coordination with Indian Tribal Governments

                    This direct final rule has no tribal implications because it will not have substantial direct effects on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, nor on the distribution of power and responsibilities between the Federal Government and Indian tribes as specified in Executive Order 13175, entitled                     *Consultation and Coordination with Indian Tribal Governments*                     (59 FR 22951, November 6, 2000).                

### G.  Executive Order 13045: Protection of Children from Environmental Health Risks and Safety Risks

Executive Order 13045, entitled                     *Protection of Children from Environmental Health Risks and Safety Risks*                     (62 FR 19885, April 23,1997), does not apply to this direct final rule because this is not an economically significant regulatory action as defined under Executive Order 12866, and it does not concern an environmental health or safety risk that may have a disproportionate effect on children.                

### H.  Executive Order 13211: Actions that Significantly Affect Energy Supply, Distribution, or Use

                    This rule is not subject to Executive Order 13211, entitled                     *Actions that Significantly Affect Energy Supply, Distribution, or Use*                     (66 FR 28355, May 22, 2001), because this action is not expected to affect energy supply, distribution, or use.                

### I.  National Technology Transfer and Advancement Act

                    Because this action does not involve any technical standards, section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 note), does not apply to this action.                          ( print page 21123)    

### J.  Executive Order 12898: Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations

                    This action does not involve special considerations of environmental justice-related issues pursuant to Executive Order 12898, entitled                     *Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations*                     (59 FR 7629, February 16, 1994).                

## VI.  Congressional Review Act

                    The Congressional Review Act, 5 U.S.C. 801*et seq*., generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the                     **Federal Register**                    . This rule is not a major rule as defined by 5 U.S.C. 804(2).
