2012-6430. Revocation of TSCA Section 4 Testing Requirements for Certain High Production Volume Chemical Substances

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Direct final rule.

SUMMARY:

EPA is revoking certain testing requirements for six chemical substances and all the testing requirements for four chemical substances. EPA is basing its decision to take this action on information received since publication of the first test rule for certain high production volume chemical substances (HPV1). HPV1 established testing requirements for those 10 chemical substances. On the effective date of this direct final rule, persons who export or intend to export the four chemical substances for which all the testing requirements are revoked are no longer subject to section 12(b) of the Toxic Substance Control Act (TSCA) export notification requirements triggered by HPV1.

DATES:

This direct final rule is effective May 15, 2012 without further notice, unless EPA receives adverse comment in writing, or a request to present comment orally, on or before April 16, 2012. If EPA receives adverse comment, or a written request for an opportunity to present oral comments, EPA will publish a timely withdrawal in the Federal Register informing the public that this direct final rule, or relevant portions of this direct final rule, will not take effect. If you write EPA to request an opportunity to present oral comments on or before April 16, 2012, EPA will hold a public meeting on this direct final rule in Washington, DC. The announcement of the meeting will be published in the Federal Register.

viii. Make sure to submit your comments by the comment period deadline identified.

II. Statutory Authority

Section 4(a) of TSCA authorizes EPA to require testing if certain findings are made. EPA is amending the chemical testing requirements for certain HPV chemical substances in 40 CFR 799.5085 because some of the findings that EPA made for 10 chemical substances are no longer supported. These findings were that:

1. The chemical substances were produced in substantial quantities.

2. There are insufficient data upon which the effects of manufacture, distribution, processing, use, or disposal of those chemical substances 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); also, see Ref. 1).

Unit III. discusses which findings are not supported for each specific chemical substance subject to this direct final rule.

III. Amendment to Chemical Testing Requirements

EPA is amending the chemical testing requirements for certain HPV chemical substances in 40 CFR 799.5085 by direct final rule. Specifically, this direct final rule revokes the testing requirements for the following four chemical substances: Acetyl chloride (CAS No. 75-36-5); imidodicarbonic diamide (CAS No. 108-19-0); methane, isocyanato- (CAS No. 624-83-9); and urea, reaction products with formaldehyde (CAS No. 68611-64-3). This direct final rule also revokes some of the testing requirements for the following six chemical substances: 9,10-Anthracenedione (CAS No. 84-65-1); 1-chlorododecane (CAS No. 112-52-7); phenol, 4,4′-methylenebis [2,6-bis(1,1-dimethylethyl)]- (CAS No. 118-82-1); methanesulfinic acid, hydroxyl-, monosodium salt (CAS No. 149-44-0); benzenesulfonic acid, [[4-[[4-(phenylamino)phenyl][4-(phenylimino)-2,5-cyclohexadien-1-ylidene]methyl]phenyl]amino]- (CAS No. 1324-76-1); and C.I. Solvent Black 7 (CAS No. 8005-02-5). EPA is basing its decision to revoke all testing requirements for four chemical substances and some of the testing requirements for six other chemical substances on information received since publication of HPV1 (40 CFR 799.5085), as described in this unit.

A. Revocation of All Testing Requirements for Four Chemical Substances

1. Acetyl chloride. EPA is revoking all testing requirements for acetyl chloride (CAS No. 75-36-5) because there is no longer support for the TSCA section 4(a)(1)(B)(i) “substantial production” finding for this chemical substance. “Substantial production” of a chemical substance under TSCA section 4(a)(1)(B)(i) is generally interpreted by EPA to be an aggregate production (including import) volume equaling or exceeding 1 million pounds per year. See EPA's TSCA section 4(a)(1)(B) Final Statement of Policy (“B” policy) (Ref. 2). The “substantial production” finding for this chemical substance was based on reports from several companies to the 2002 TSCA Inventory Update Reporting (IUR) rule. The Albemarle Corporation which manufactured and imported the largest volume of acetyl chloride, without which a finding of substantial production could not have been made, informed EPA in 2007 that its manufacture and importation of acetyl chloride at the time the test rule was promulgated were only for non-TSCA purposes (i.e., for use in pharmaceuticals) (Ref. 3), and was, therefore, not subject to HPV1.

Three other companies had reported importing smaller volumes of acetyl chloride in the 2002 IUR, the sum of which would not have provided support for a finding of substantial production. Two of these companies, Tessenderlo Kerley, Inc., and a company, which claimed its name as CBI, have since ceased importation of acetyl chloride. Tessenderlo Kerley ceased importation several years ago, and the other company ceased importation over a year prior to the effective date of HPV1, April 17, 2006 (Ref. 4). Neither of these companies is, therefore, subject to HPV1. The third small importer, Chartkit Chemical Corporation, reported that it imported only a small amount of acetyl chloride after the effective date of HPV1 in 2006, but none since (Ref. 5). EPA's review of data in the 2006 IUR (which required reporting on chemical substances manufactured or imported during calendar year 2005) did not identify any companies manufacturing or importing acetyl chloride. (Chartkit Chemical Corporation did not import acetyl chloride in 2005, making a report to the 2006 IUR unnecessary.) Because the finding for substantial production for acetyl chloride was not supported when HPV1 was promulgated, the Agency is revoking all the testing requirements for acetyl chloride (CAS No. 75-36-5) by removing it from Table 2 in 40 CFR 799.5085(j).

2. Imidodicarbonic diamide. EPA is revoking all the testing requirements for imidodicarbonic diamide (CAS No. 108-19-0), also known as biuret, by removing imidodicarbonic diamide from Table 2 in 40 CFR 799.5085(j). EPA considers the test requirements for this chemical substance unnecessary at this time because sufficient data have been provided to allow the Agency to reverse its finding under TSCA section 4(a)(1)(B)(ii) for “insufficient data.” Information that satisfied HPV1's requirements was voluntarily submitted by The Fertilizer Institute (TFI) on behalf of a member company that manufactures the chemical substance as an impurity in its products. EPA considers a company that manufactures a chemical substance only as an impurity to be a Tier 2 manufacturer with regard to its obligations under HPV1. Although subject to HPV1 and responsible for providing reimbursement to persons in Tier 1, Tier 2 manufacturers do not have to respond to HPV1 with a letter of intent to test or a request for exemption, unless directed to do so by EPA through a document published in the Federal Register. Although EPA did not publish such a document, TFI, acting on behalf of its member company, volunteered to provide information to EPA on the endpoints specified by HPV1 for that chemical substance. This information (Refs. 6-8) was provided to the Agency and found to meet the standards prescribed by EPA (Refs. 9-11) and is being made available in the docket for this direct final rule and will be added to the High Production Volume Information System (HPVIS).

3. Methane, isocyanato. EPA is revoking all the testing requirements for methane, isocyanato- (CAS No. 624-83-9) by removing it from Table 2 in 40 CFR 799.5085(j). On May 11, 2007, Bayer CropScience submitted a test plan and robust summaries of existing data for methane, isocyanato- along with a request that EPA determine if the robust summaries satisfied the Agency's need for data on physical/chemical properties (Ref. 12). In the same letter, Bayer CropScience requested a waiver for the requirement to determine an octanol-water partition coefficient and the requirement to conduct aquatic toxicity tests because of the extreme reactivity in water of methane, isocyanato-. Bayer CropScience also asked EPA to consider, as a substitute for aquatic toxicity studies of methane, isocyanato-, robust summaries of aquatic toxicity studies of dimethyl urea (CAS No. 96-31-1) (DMU), one of the two degradation products of methane, isocyanato- in water, the other being carbon dioxide. EPA concluded that the submitted data satisfied the Agency's need for data on the physical/chemical properties of boiling point, melting point, vapor pressure, and water solubility (Ref. 13). EPA also agreed that methane, isocyanato- hydrolyzes very rapidly and, as a result, an octanol-water partition coefficient is not relevant (Ref. 13). Because of the rapid hydrolysis of methane, isocyanato- to carbon dioxide and DMU, EPA is revoking the requirement to test for aquatic toxicity (fish acute toxicity, Daphnia acute toxicity, and toxicity to algae). EPA believes that the aquatic toxicity studies of DMU, provided by Bayer CropScience, which the Agency reviewed and found adequate, provide information on the aquatic effects of methane, isocyanato- (Ref. 14). Therefore, EPA, in this direct final rule, is revoking the testing requirements for boiling point, melting point, vapor pressure, octanol-water partition coefficient, water solubility, fish acute toxicity, Daphnia acute toxicity, and toxicity to algae for methane, isocyanato- by removing it from Table 2 in 40 CFR 799.5085(j).

4. Urea, reaction products with formaldehyde. EPA is revoking all the testing requirements for urea, reaction products with formaldehyde (CAS No. 68611-64-3) by removing it from Table 2 in 40 CFR 799.5085(j). EPA considers the test requirements for this chemical substance unnecessary at this time because sufficient data have been provided to allow the Agency to reverse its finding under TSCA section 4(a)(1)(B)(ii) for “insufficient data.” Information which satisfied HPV1's requirements was voluntarily submitted by TFI on behalf of its member companies that manufacture this chemical substance as an impurity in their products. EPA considers companies that manufacture a chemical substance only as an impurity to be Tier 2 manufacturers with regard to their obligations under HPV1. Although subject to HPV1 and responsible for providing reimbursement to persons in Tier 1, Tier 2 manufacturers did not have to respond to HPV1 with a letter of intent to test or a request for exemption, unless directed to do so by EPA through a document published in the Federal Register. Despite the lack of an EPA published Federal Register document, TFI, acting on behalf of its member companies, volunteered to provide information to EPA on the endpoints specified by HPV1 for this chemical substance. This information (Refs. 7 and 16) has been provided to the Agency and found to meet the standards for testing prescribed by EPA (Refs. 17-19) and is being made available in the docket for this direct final rule and will be added to HPVIS.

B. Revocation of Some Test Requirements for Six Chemical Substances

1. 9,10-Anthracenedione. In a letter dated July 10, 2006, the Chemical Products Corporation (CPC) requested EPA's permission to submit the values for boiling point and vapor pressure of 9,10-anthracenedione (CAS No. 84-65-1) contained in the International Uniform Chemical Information Database (IUCLID) instead of conducting the tests required by HPV1 (Ref. 20). CPC stated that the ASTM methods specified by HPV1 would not work for 9,10-anthracenedione because the boiling point and vapor pressure listed for that chemical substance in IUCLID and the boiling point listed for that chemical substance in the “Handbook of Chemistry and Physics” (Ref. 21) fell outside the determination ranges of the ASTM methods. EPA agreed and approved CPC's request to submit IUCLID and other existing values because those values matched or were in close agreement with measured values in various literature sources (Ref. 22). CPC also requested a modification of the ASTM method E 324 to determine the melting point for 9,10-anthracenedione (Ref. 23). While evaluating this request, EPA reviewed available data on measured melting points of 9,10-anthracenedione and found the existing data to be in sufficiently close agreement that they could be used to satisfy the Agency's data need for that endpoint (Ref. 22). EPA is, therefore, revoking the requirement that the boiling point, vapor pressure, and melting point of 9,10-anthracenedione be determined by the ASTM methods specified in HPV1 and accepts the submitted existing data as sufficient to satisfy those data needs, making the testing requirements unnecessary. Therefore, EPA is revoking the testing requirements for boiling point, vapor pressure, and melting point for 9,10-anthracenedione by removing those requirements from those listed for 9,10-anthracenedione in Table 2 in 40 CFR 799.5085(j). The test requirements for 9,10-anthracenedione that are not revoked by this direct final rule include tests to determine octanol/water partition coefficient and water solubility, and to screen for reproduction/developmental toxicity. Studies responding to those test requirements have been submitted to the Agency (Ref. 24).

2. 1-Chlorododecane. In a letter dated February 21, 2008, EPA informed Lonza, Inc., that the testing of 1-chlorododecane (CAS No. 112-52-7), which Lonza had committed to sponsor, did not have to include a test for melting point because, in publicly available documents, 1-chlorododecane is reported to be a liquid (Ref. 25). Therefore, EPA is revoking the testing requirement for melting point for 1-chlorododecane by removing that requirement from those listed for 1-chlorododecane in Table 2 in 40 CFR 799.5085(j). The test requirements for 1-chlorododecane that are not revoked by this direct final rule include tests for boiling point, vapor pressure, octanol/water partition coefficient, water solubility, biodegradation, Daphnia chronic toxicity, toxicity to algae, acute mammalian toxicity, mutagenicity, chromosomal damage, and 28-day repeated-dose toxicity with a reproduction/developmental toxicity screen. Studies responding to those test requirements have been submitted to the Agency (Ref. 26).

3. Phenol, 4,4′-methylenebis[2,6-bis(1,1-dimethylethyl)]-. In letters dated May 12, 2006, July 14, 2006, May 1, 2007, and May 16, 2007 (Refs. 27-30), the Albemarle Corporation requested EPA to review existing data that it was submitting for phenol, 4,4′-methylenebis[2,6-bis(1,1-dimethylethyl)]- (CAS No. 118-82-1) to determine if they satisfied the Agency's need for data on water solubility, octanol/water partition coefficient, acute mammalian toxicity, bacterial reverse mutation, and screening level reproduction/developmental toxicity. EPA found that the data satisfied the Agency's data needs for those testing endpoints in HPV1, making the testing requirements unnecessary (Refs. 31-33). Therefore, EPA is revoking the testing requirements for water solubility, octanol/water partition coefficient, acute mammalian toxicity, bacterial reverse mutation assay, and a reproduction/developmental toxicity screen for phenol, 4,4′-methylenebis[2,6-bis(1,1-dimethylethyl)]- by removing those requirements from Table 2 in 40 CFR 799.5085(j). The test requirements for phenol, 4,4′-methylenebis[2,6-bis(1,1-dimethylethyl)]- that are not revoked by this direct final rule include tests for melting point, boiling point, vapor pressure, inherent biodegradation, and chromosomal damage. Studies responding to those test requirements have been submitted to the Agency (Ref. 34).

4. Methanesulfinic acid, hydroxyl-, monosodium salt. On May 14, 2007, the Sodium Formaldehyde Sulfoxylate Consortium (SFS Consortium) formed under the auspices of the Synthetic Organic Chemical Manufacturers Association (SOCMA) submitted existing data to satisfy some of the testing requirements for methanesulfinic acid, hydroxyl-, monosodium salt (CAS No. 149-44-0) (Ref. 35). The submitted studies used the dihydrate form of methanesulfinic acid, hydroxyl-, monosodium salt (CAS No. 6035-47-8) as the test substance to address the endpoints of inherent biodegradation, fish acute toxicity, Daphnia acute toxicity, and toxicity to algae (Ref. 35). Although the hydrated form is identified by a different CAS number, in general, EPA does not recognize a hydrate as a separate entity from the corresponding anhydrous material for TSCA purposes, and accepts studies of the hydrated form of a chemical substance as predictive of the effects of the anhydrous chemical (Ref. 15). EPA found that the submitted study on ready biodegradation satisfied the need for information on biodegradability, making the test requirement for inherent biodegradation unnecessary (Refs. 36 and 37). The existing studies on fish acute toxicity, Daphnia acute toxicity, and toxicity to algae were reviewed by the Agency and found to satisfy EPA's data needs for those endpoints (Ref. 38).

In the test plan submitted with the May 14, 2007 letter, the SFS Consortium requested that EPA revoke the requirement to determine vapor pressure because the chemical substance is an organo-metallic salt that does not volatilize (Ref. 35). The SFS Consortium also requested that EPA revoke the requirement to determine the octanol/water partition coefficient (log K_ow) because its estimated value was −6.17 and HPV1 did not require a determination of octanol/water partition coefficient if its estimated value is less than zero (Ref. 35). EPA agreed with the SFS Consortium's position that testing was not needed to determine vapor pressure (Ref. 39) and octanol/water partition coefficient (Ref. 40). Also, in the test plan submitted on May 14, 2007, (Ref. 35), the SFS Consortium reported that in a test to determine boiling point, the test substance decomposed. EPA, therefore, is waiving the test for boiling point (Ref. 41).

EPA is revoking the testing requirements for boiling point, vapor pressure, octanol/water partition coefficient, biodegradation, fish acute toxicity, Daphnia acute toxicity, and toxicity to algae for methanesulfinic acid, hydroxyl-, monosodium salt by removing those requirements from those listed for that chemical substance in Table 2 in 40 CFR 799.5085(j). The testing requirements for methanesulfinic acid, hydroxyl-, monosodium salt that are not revoked by this direct final rule include tests for melting point, water solubility, chromosomal damage, and 28-day repeated-dose toxicity with a reproduction/developmental toxicity screen. Studies responding to those test requirements, also using the dihydrate form of methanesulfinic acid, hydroxyl-, monosodium salt, were submitted to the Agency (Ref. 42).

5. Benzenesulfonic acid, [[4-[[4-(phenylamino)phenyl][4-(phenylimino)-2,5-cyclohexadien-1-ylidene]methyl]phenyl]amino]-. On July 17, 2006, the Color Pigments Manufacturers Association (CPMA) submitted a test plan for benzenesulfonic acid, [[4-[[4-(phenylamino)phenyl][4-(phenylimino)-2,5-cyclohexadien-1-ylidene]methyl]phenyl]amino]- (CAS No. 1324-76-1), also known as 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. 43 and 44). CPMA also asked EPA to accept results for water solubility and octanol/water partition coefficient which 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. 43). 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. 43).

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. 45). 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. 45). EPA believes the calculated value would, most likely, underestimate the measured value (Ref. 45) required to be determined by HPV1.

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 acceptable surrogate 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. 46). 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. 46). Likewise, a chromosomal damage test of C.I. Pigment Blue 56, which EPA reviewed and found adequate, will satisfy the data need for that endpoint (Ref. 47) for C.I. Pigment Blue 61. EPA's review of the existing data on C.I. Pigment Blue 61 found the studies on fish acute toxicity, mammalian acute toxicity, and bacterial mutation assay to be adequate to satisfy the data needs for those endpoints (Ref. 47). The existing study on repeated-dose toxicity, however, did not satisfy the test requirement for that endpoint (Ref. 47).

Therefore, EPA is revoking 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 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 revoked by this direct final rule 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 were claimed to be CBI and are not available to the public, but robust summaries of those studies (Ref. 48) are in the docket.

6. C.I. Solvent Black 7. On July 29, 2006 and August 4, 2006, the Solvent Black 7 Consortium formed under the auspices of SOCMA submitted eight existing studies on C.I. Solvent Black 7 (CAS No. 8005-02-5) and requested EPA to determine if they satisfied some of the Agency's data needs specified in HPV1 (Ref. 49). EPA found that the studies satisfied the need for data on inherent biodegradation, fish acute toxicity, Daphnia acute toxicity, toxicity to algae, acute mammalian toxicity, chromosomal damage, and repeated-dose 28-day oral toxicity in rodents, making those test requirements for C.I. Solvent Black 7 unnecessary (Ref. 50). Although the 28-day oral toxicity study in rodents was accepted, it lacked a required screening test for reproduction/developmental toxicity. Although a test for chronic toxicity to Daphnia was not required for this chemical substance, SOCMA submitted a Daphnia magna reproduction test because the log K_ow of C.I. solvent Black 7 is close to 4.2 and a log K_ow greater than 4.2 would have made a Daphnia chronic toxicity test a requirement (Refs. 1 and 51). The submitted study was evaluated and was not found adequate to satisfy the objectives of a Daphnia chronic toxicity study because the study was only 10 days long instead of 21 days, and only one concentration was tested and it was lethal, preventing observation of sub-lethal endpoints (Ref. 52).

Therefore, EPA is revoking the testing requirements for inherent biodegradation, fish acute toxicity, Daphnia acute toxicity, toxicity to algae, acute mammalian toxicity, chromosomal damage, and repeated-dose 28-day oral toxicity in rodents for C.I. Solvent Black 7 (CAS No. 8005-02-5) 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 the requirement for a reproduction/developmental toxicity screening test had not been satisfied, but that the requirement for a repeated-dose 28-day oral toxicity test had been satisfied, the test symbol F2 replaces F1 for C.I. Solvent Black 7 in Table 2 in 40 CFR 799.5085(j). The testing requirements not revoked by this direct final rule include the tests to determine five physical/chemical properties and to screen for reproduction/developmental toxicity. Studies responding to those test requirements have been submitted to the Agency (Refs. 51 and 53).

IV. Economic Analysis

In the economic impact analysis of this direct final rule, the Agency estimated the total testing cost to industry to be $4.03 million for all 17 chemical substances, with an average of approximately $237,000 per chemical substance (Ref. 54). This total included an additional 25% in administrative costs. An amendment to HPV1 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 direct final rule would have the effect of further reducing the total testing cost by an estimated $1.5 million (approximately 41%), by eliminating all the testing requirements for acetyl chloride; imidodicarbonic diamide; methane, isocyanato-; and urea, reaction products with formaldehyde; as well as some of the testing requirements for 9,10-anthracenedione; 1-chlorododecane; phenol, 4,4′-methylenebis [2,6-bis (1,1-dimethylethyl)]-; methanesulfinic acid, hydroxy-, monosodium salt; benzenesulfonic acid, [[4-[[4-(phenylamino)phenyl][4-(phenylmino)-2,5-cyclohexadien-1-ylidene]methyl]phenyl]amino]-; and C.I. Solvent Black 7 (Ref. 55). In addition, the 25% administrative costs would be eliminated for these tests. The reduced total cost for the remaining 12 chemical substances with testing requirements is estimated to be $2.2 million (i.e., $3.7 million minus $1.5 million), with an average compliance cost per chemical substance of approximately $184,000 (Ref. 55).

V. Export Notification

On the effective date of the revocations in this direct final rule of the TSCA section 4 testing requirements for acetyl chloride (CAS No. 75-36-5); imidodicarbonic diamide (CAS No. 108-19-0), methane, isocyanato- (CAS No. 624-83-9); and urea, reaction products with formaldehyde (CAS No. 68611-64-3), persons who export or intend to export those chemical substances will no longer be subject to any TSCA section 12(b) export notification requirements triggered by HPV1 (See 40 CFR part 707, subpart D). The export notification requirements remain the same for the other six chemical substances discussed in the preamble of this direct final rule that are listed as subject to the requirements of HPV1 (Ref. 1); these chemical substances are 9,10-anthracenedione (CAS No. 84-65-1); 1-chlorododecane (CAS No. 112-52-7); phenol, 4,4′-methylenebis[2,6-bis(1,1-dimethylethyl)]- (CAS No. 118-82-1); methanesulfinic acid, hydroxy-, monosodium salt (CAS No. 149-44-0); benzenesulfonic acid, [[4-[[4-(phenylamino)phenyl][4-(phenylimino)-2,5-cyclohexadien-1-ylidene]methyl]phenyl]amino]- (CAS No. 1324-76-1); and C.I. Solvent Black 7 (CAS No. 8005-02-5).

VI. Direct Final Rule Procedures

EPA is publishing this direct final rule without prior proposal because the Agency views this as a non-controversial amendment and anticipates no adverse comment as this action simply revokes testing which is not feasible, or testing for which the substantial production finding was not supported, or testing for which EPA has adequate data at this time. This direct final rule is effective May 15, 2012 without further notice, unless EPA receives adverse comment or a written request for an opportunity to present oral comments on or before April 16, 2012. If EPA receives adverse comment or a written request for an opportunity to present oral comments on one or more distinct amendments, paragraphs, or sections of this direct final rule, the Agency will publish a timely withdrawal in the Federal Register indicating which provisions will become effective and which provisions are being withdrawn due to adverse comment or a written request for an opportunity to present oral comments. Any distinct amendment, paragraph, or section of this direct final rule for which the Agency does not receive adverse comment or a request for an opportunity to present oral comments is effective May 15, 2012, notwithstanding any adverse comment or request on any other distinct amendment, paragraph, or section of this direct final rule. For any distinct amendment, paragraph, or section of this direct final rule that is withdrawn due to adverse comment or a request for an opportunity to present oral comments, EPA will publish a notice of proposed rulemaking in a future issue of the Federal Register. The Agency will address the comment or request for an opportunity to present oral comments on any such distinct amendment, paragraph, or section as part of that notice of proposed rulemaking.

VIII. Statutory and Executive Order Reviews

This direct final rule only eliminates existing requirements; it does not otherwise 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 (PRA) (44 U.S.C. 3501 et seq.).

Because this direct final 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 sections 203 and 204 of UMRA. This direct final 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 13211, “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 direct final 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).

IX. 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 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).
