II. Background

A. What action is the Agency taking?

EPA is proposing to amend the TSCA section 4(a) chemical testing requirements for one high production volume (HPV) chemical included in 40 CFR 799.5085. Specifically, this amendment revokes some of the testing requirements for C.I. Pigment Blue 61. EPA is basing its decision to take this action on information (discussed in Unit III.) received since publication of the final rule (Ref. 1) that established testing requirements for this chemical substance.

In theFederal Registerof March 16, 2012 (77 FR 15609) (FRL-9335-6), EPA issued a revocation of some or all of the testing requirements for 10 chemical substances by direct final rule. EPA received an adverse comment concerning the chemical substance C.I. Pigment Blue 61. Consequently, in accordance with the procedures described in the March 16, 2012Federal Registerdocument, EPA is withdrawing the revocation of certain testing requirements for C.I. Pigment Blue 61 in a separate document published elsewhere in today'sFederal Register, and is now issuing this proposed rule.

B. What is the Agency's authority for taking this action?

Section 4(a) of TSCA authorizes EPA to require testing if certain findings are made. The TSCA section 4(a) findings include:

1. The chemical substance was produced in substantial quantities.

2. There are insufficient data upon which the effects of manufacture, distribution, processing, use, or disposal of a chemical substance on health or the environment can reasonably be determined or predicted.

3. Testing of the chemical substance with respect to such effects is necessary to develop such data. (See TSCA section 4(a)(1)(B)(i), (ii), and (iii); see also Ref. 1).

EPA is amending the testing requirements for C.I. Pigment Blue 61 because some of the findings that EPA made for this chemical substance are no longer supported.

III. Amendment to Chemical Testing Requirements

On July 17, 2006, the Color Pigments Manufacturers Association (CPMA) submitted a test plan for C.I. Pigment Blue 61. CPMA also submitted robust summaries of existing data which CPMA asked EPA to accept as satisfying some of the Agency's data needs for C.I. Pigment Blue 61. Some of the existing data described in the summaries addressed C.I. Pigment Blue 56, a close analog of C.I. Pigment Blue 61, which CPMA requested EPA to accept as satisfying the Agency's data needs for C.I. Pigment Blue 61, providing a structure-activity relationship (SAR) argument in the test plan to justify that request (Refs. 2 and 3). CPMA also asked EPA to accept results for water solubility and octanol/water partition coefficient that were obtained by using an alternative method, due to the extremely low predicted solubility of C.I. Pigment Blue 61, instead of the methods specified by the test rule (Ref. 2). Finally, CPMA asked EPA to accept that determining a melting point for C.I. Pigment Blue 61 was not relevant because the pigment thermally decomposes before it melts (Ref. 2).

EPA reviewed the submitted information on physical/chemical properties and decided that melting point, boiling point, and vapor pressure determinations were not relevant because C.I. Pigment Blue 61 decomposes before it melts and the decomposition temperature had been reported (Ref. 4). EPA accepted the submitted data on water solubility as satisfying the Agency's data needs for that endpoint, but did not accept the calculated value submitted to satisfy the testing requirement for octanol/water partition coefficient (Ref. 4). EPA believes the calculated value would, most likely, underestimate the measured value (Ref. 4) required to be determined by the test rule.

EPA reviewed CPMA's SAR argument concerning C.I. Pigment Blue 61 and C.I. Pigment Blue 56 and agreed that C.I. Pigment Blue 56 is an acceptablesurrogate for C.I. Pigment Blue 61, thereby allowing adequate data on C.I. Pigment Blue 56 to satisfy data needs for C.I. Pigment Blue 61 (Ref. 5). As a result, a biodegradation study of C.I. Pigment Blue 56, found adequate by an EPA review, satisfies the need for biodegradation data on C.I. Pigment Blue 61 (Ref. 5). Likewise, a fish acute toxicity study and a chromosomal damage test of C.I. Pigment Blue 56, which EPA reviewed and found adequate, will satisfy the data need for those endpoints (Ref. 6) for C.I. Pigment Blue 61. EPA's review of the existing data on C.I. Pigment Blue 61 found the study on mammalian acute toxicity and the bacterial mutation assay to be adequate to satisfy the data needs for those endpoints (Ref. 6). The existing study on repeated-dose toxicity, however, did not satisfy the test requirement for that endpoint (Ref. 6).

Therefore, EPA is proposing to revoke the testing requirements for melting point, boiling point, vapor pressure, water solubility, biodegradation, fish acute toxicity, mammalian acute toxicity, bacterial reverse mutation, and chromosomal damage for C.I. Pigment Blue 61 by removing those requirements from those listed for that chemical substance in Table 2 in 40 CFR 799.5085(j). In order to clarify that test requirements for acute toxicity to Daphnia (an aquatic invertebrate) and toxicity to algae had not been satisfied by existing studies, and that the fish acute toxicity test requirement had been satisfied, the test symbol C2 replaces C1 for C.I. Pigment Blue 61 in Table 2 in 40 CFR 799.5085(j). The testing requirements for C.I. Pigment Blue 61 that are not proposed to be revoked include tests for octanol/water partition coefficient, acute toxicity to Daphnia, toxicity to algae, and combined 28-day repeated-dose toxicity with a reproduction/developmental toxicity screen. Studies responding to those test requirements were submitted to the Agency. The full studies and robust summaries (Ref. 7) are in the docket for this proposed rule, docket ID number EPA-HQ-OPPT-2005-0033.

IV. Public Comment

EPA received one adverse comment concerning the March 16, 2012 direct final rule that revoked some of the testing requirements for C.I. Pigment Blue 61 and nine other chemical substances. The comment concerned the statement in the preamble of the direct final rule that certain full studies for C.I. Pigment Blue 61 had been claimed as CBI and were therefore not available to the public, although robust summaries were available in the docket. The commenter objected to EPA's placing the robust summaries in the docket rather than applying the disclosure requirements of TSCA section 14(b) to the full health and safety studies. The submitter of these studies has subsequently withdrawn the CBI claim on these studies. The full studies and the adverse comment are included in the docket for this proposed rule, docket ID number EPA-HQ-OPPT-2005-0033.

V. Economic Analysis

In the economic impact analysis for the final rule (Ref. 1) establishing testing requirements for C.I. Pigment Blue 61 and 16 other chemical substances, the Agency estimated the total testing cost to industry to be $4.03 million for all 17 chemical substances included in that final rule, with an average of approximately $237,000 per chemical substance (Ref. 8). This total included an additional 25% in administrative costs. An amendment to the final rule revoking testing requirements for coke-oven light oil (coal) reduced the total cost to industry to an estimated $3.7 million for the remaining 16 chemical substances, with an average compliance cost of approximately $232,000 per chemical substance. This proposed rule, combined with the direct final rule revoking all or some of the test rule requirements for 9 other chemical substances (see Ref. 1), would have the effect of further reducing the total testing cost by an estimated $1.5 million (approximately 41%) (Ref. 9). In addition, the 25% administrative costs would be eliminated for these tests. The reduced total cost for the remaining 12 chemical substances is estimated to be $2.2 million (i.e., $3.7 million—$1.5 million), with an average compliance cost per chemical substance of approximately $184,000 (Ref. 9).

VI. Export Notification

Persons who export or intend to export C.I. Pigment Blue 61 are and will remain subject to TSCA section 12(b) export notification requirements (See 40 CFR part 707, subpart D).

VIII. Statutory and Executive Order Reviews

This proposed rule only eliminates existing requirements; it does nototherwise impose any new or revised requirements. As such, this action is not subject to review by the Office of Management and Budget (OMB) as a significant regulatory action under Executive Order 12866, entitled “Regulatory Planning and Review” (58 FR 51735, October 4, 1993). Nor does it impose or change any information collection burden that requires additional review by OMB under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

Because this proposed rule eliminates existing requirements without imposing any new or revised 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 economic impact on a substantial number of small entities.

For the same reasons, it is not subject to the requirements of sections 202 and 205 of the Unfunded Mandates Reform Act (UMRA) (2 U.S.C. 1531-1538), and does not significantly or uniquely affect small governments or impose a significant intergovernmental mandate, as described in UMRA sections 203 and 204. This proposed rule does not have tribal implications, as specified in Executive Order 13175, entitled “Consultation and Coordination with Indian Tribal Governments” (65 FR 67249, November 9, 2000), or federalism implications as specified in Executive Order 13132, entitled “Federalism” (64 FR 43255, August 10, 1999).

Since this action is not economically significant under Executive Order 12866, it is not subject to Executive Order 13045, entitled “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997), and Executive Order 13211, entitled “Actions concerning Regulations that Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001).

This action does not involve technical standards; thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply.

This proposed rule does not involve special consideration of environmental justice related issues as specified in Executive Order 12898, entitled “Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations” (59 FR 7629, February 16, 1994).
