    Prohibition of Hexavalent Chromium-Based Water Treatment 
    Chemicals in Comfort Cooling Towers; Amendment To Limit the Scope of

    AGENCY: Environmental Protection Agency (EPA).
    
    ACTION: Final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: This rule amends 40 CFR part 749, subpart D, which prohibits, 
    under section 6 of the Toxic Substances Control Act (TSCA), the use of 
    hexavalent chromium-based water treatment chemicals in comfort cooling 
    towers and the distribution of such chemicals in commerce for use in 
    comfort cooling towers. Today's action amends 40 CFR 749.68 to clarify 
    that only hexavalent chromium chemicals that can be used for water 
    treatment are the subjects of this regulation, not other hexavalent 
    chromium chemicals. This amendment limits the scope of export 
    notifications currently required for hexavalent chromium chemicals 
    under TSCA section 12(b), the TSCA Export Notification Rule (40 CFR 
    part 707), and Sec. 749.68. No changes to the prohibitions or labeling 
    requirements of the hexavalent chromium rule are intended by this 
    amendment. As amended, Sec. 749.68 does not trigger the section 12(b) 
    export notification requirements for exports of hexavalent chromium 
    products such as certain paints, dyes, pigments, coatings, 
    electroplating and conversion coating products, and other products 
    containing hexavalent chromium that cannot be used to treat water.
    
    DATES: This rule shall become effective on September 19, 1994. In 
    accordance with 40 CFR 23.5, this rule shall be promulgated for 
    purposes of judicial review at 1 p.m. eastern daylight time (or 
    standard time) on September 2, 1994.
    
    FOR FURTHER INFORMATION CONTACT: Geraldine Gardner, Office of 
    Enforcement and Compliance Assurance (2245), Environmental Protection 
    Agency, 401 M St., SW., Washington, DC 20460, Telephone: 202-260-8858.
    
    SUPPLEMENTARY INFORMATION: In the Federal Register of November 30, 1993 
    (58 FR 63148), EPA proposed an amendment to 40 CFR part 749, subpart D, 
    which prohibits the use of hexavalent chromium (Cr+6)-based water 
    treatment chemicals in comfort cooling towers (CCTs) and the 
    distribution of such chemicals in commerce for use in CCTs. The 
    regulatory text of today's amendment is identical to the regulatory 
    text of the proposed amendment. Comments received on the proposed 
    amendment are addressed in Unit V of this preamble. Today's amendment 
    modifies 40 CFR 749.68 to clarify that only Cr+6 chemicals that 
    can be used for water treatment are the subjects of the regulation, not 
    other Cr+6 chemicals. This change limits the scope of TSCA section 
    12(b) export notifications currently required for Cr+6 chemicals.
    
    I. Authority
    
        This amendment is being promulgated pursuant to TSCA sections 6 (15 
    U.S.C. 2605) and 12(b) (15 U.S.C. 2611(b)). Section 6 of TSCA 
    authorizes EPA to impose regulatory controls if EPA finds that there is 
    a reasonable basis to conclude that the manufacture, processing, 
    distribution in commerce, use, or disposal of a chemical substance or 
    mixture presents or will present an unreasonable risk of injury to 
    human health or the environment. Under this authority, EPA issued a 
    final rule in the Federal Register of January 3, 1990 (55 FR 222), that 
    prohibits the use of Cr+6-based water treatment chemicals in CCTs 
    and the distribution in commerce of Cr+6-based water treatment 
    chemicals for use in CCTs (40 part CFR 749, subpart D). The rule also 
    requires persons who distribute in commerce Cr+6-based water 
    treatment chemicals to label the containers of the chemicals.
        Section 12(b) of TSCA requires that any person who exports or 
    intends to export to a foreign country a chemical substance or mixture 
    for which: (1) The submission of data is required under TSCA section 4 
    (15 U.S.C. 2603) or 5(b) (15 U.S.C. 2604(b)); (2) an order has been 
    issued under section 5; (3) a rule has been proposed or promulgated 
    under section 5 or 6 (15 U.S.C. 2605); or (4) relief has been granted 
    under section 5 or 7 (15 U.S.C. 2606) to notify the Administrator of 
    EPA of such exportation or intent to export. Upon receipt of such 
    notification, section 12(b) of TSCA requires EPA to furnish the 
    government of the importing country with: notice of the availability of 
    data received pursuant to action under section 4 or 5(b), or notice of 
    such rule, order, action, or relief under section 5, 6, or 7. EPA 
    promulgated a rule setting forth the export notification requirements 
    of TSCA section 12(b) under 40 CFR part 707, subpart D. EPA amended the 
    export notification rule to limit notifications triggered by TSCA 
    section 4 actions on July 27, 1993 (58 FR 40238).
    
    II. Background
    
        Because the Cr+6 rule was promulgated under TSCA section 6, 
    export notification requirements under section 12(b) are triggered. 
    Currently, all Cr+6 chemicals are subject to section 12(b) because 
    the term ``Cr+6 chemicals'' is presently defined in 
    Sec. 749.68(d)(10) as ``any combination of chemical substances 
    containing hexavalent chromium and includes hexavalent chromium-based 
    water treatment chemicals.'' Thus, for example, the export of paint 
    containing a Cr+6 chemical that cannot be used for water treatment 
    would currently trigger the section 12(b) notification requirements.
        In the preamble to the final Cr+6 rule, EPA stated that 
    pursuant to TSCA section 12(b) and 40 CFR part 707, subpart D, persons 
    who export or intend to export Cr+6 chemicals are required to 
    notify EPA of those activities. EPA indicated that export notification 
    would be required for all Cr+6 exports ``because the substance 
    subject to the rule is Cr+6'' and that it did not believe that the 
    requirement should be narrowed, as a practical matter, because of the 
    difficulty in determining the end use of the Cr+6 at the time of 
    export. EPA also anticipated that the burden of the notification 
    requirements that would be triggered by the export of Cr+6 for 
    uses not regulated by the rule would be minimal.
        After promulgation of the final Cr+6 rule, the Chrome 
    Coalition filed a Petition for Review with the United States Court of 
    Appeals, District of Columbia Circuit dated April 17, 1990 (Chrome 
    Coalition v. U.S. Environmental Protection Agency, No. 90-1138). In the 
    petition, the Chrome Coalition argued that because EPA failed to set 
    forth its interpretation of TSCA section 12(b) in the proposed rule, 
    the public was unable to comment on that interpretation. Additionally, 
    they argued that EPA's interpretation of section 12(b) is too broad in 
    the context of the Cr+6 rule, and imposes an unnecessary burden on 
    any business that exports products containing Cr+6, even when the 
    products cannot be used in water treatment. As a part of the settlement 
    reached with the Chrome Coalition on December 15, 1992, EPA agreed to 
    promulgate a rule that addressed the concerns raised by the Coalition. 
    The Settlement Agreement was filed with the United States Court of 
    Appeals, District of Columbia Circuit on January 7, 1993.
        In light of the Chrome Coalition's Petition, EPA reevaluated the 
    need to broadly require export notification for all Cr+6 chemicals 
    and proposed to modify the rule to clarify it on November 30, 1993 (58 
    FR 63148).
    
    III. Summary of this Final Rule
    
        EPA is amending the Cr+6 rule solely to clarify the scope of 
    coverage of the rule, thereby limiting the scope of the required 
    section 12(b) notifications. This rule will require notification under 
    40 CFR part 707, subpart D, for the export or intended export of 
    Cr+6 chemicals that can be used for water treatment. EPA is 
    listing in Sec. 749.68 certain specific Cr+6 chemicals that the 
    Agency believes can be used to treat water. This is not meant to be a 
    complete listing of all Cr+6 chemicals that can be used to treat 
    water, but rather a listing of examples. The export of any Cr+6 
    chemicals alone, or in combination with other chemical substances when 
    the mixture can be used to treat water cooling systems, will trigger 
    the TSCA section 12(b) export notification requirements.
        Under existing language of the Cr+6 rule, TSCA section 12(b) 
    export notification is required for all Cr+6 compounds, if they 
    are exported alone, or in combination with other substances, even if 
    the exported product cannot be used to treat water. With today's 
    amendment, exporters of hexavalent chromium products such as paints, 
    dyes, pigments, electroplating and conversion coating products, and 
    other substances containing Cr+6 that cannot be used to treat 
    water will not need to report the export to EPA under TSCA section 
    12(b). To accomplish this, EPA is amending the subject of the Cr+6 
    rule, certain definitions, and other appropriate provisions, as 
    discussed below.
    
    IV. Discussion of this Final Rule
    
        Exports of certain Cr+6 chemicals (e.g., in such products as 
    paints, dyes, pigments, electroplating and conversion coating products) 
    may now be triggering TSCA section 12(b) export notifications in more 
    cases than are necessary to reasonably carry out the purposes of TSCA 
    section 12(b) and the section 6 Cr+6 rule. EPA believes the 
    current burden associated with exporters providing notification for 
    exports of Cr+6 chemicals that cannot be used for water treatment 
    to be substantial, without providing any appreciable reduction in the 
    risk addressed in the Cr+6 rule. In addition, the benefits to 
    countries receiving these notifications are thought to be minimal. This 
    amendment modifies Sec. 749.68 to clarify that only Cr+6 chemicals 
    that can be used to treat water are the subjects of the Cr+6 rule. 
    Because the amended regulation will address the risk concerns 
    identified as the basis for the existing Cr+6 rule, but at a lower 
    cost, EPA finds that the amended rule will continue to protect human 
    health and the environment against unreasonable risk of injury. 
    Moreover, this change, EPA believes, will provide to importing 
    countries information more reflective of EPA's concerns and will 
    further Congress' intent, pursuant to TSCA section 2(c) (15 U.S.C. 2601 
    (c)) that EPA administer TSCA ``in a reasonable and prudent manner.''
        This change is supported by the TSCA section 6 Cr+6 rulemaking 
    effort. The supporting documentation used by EPA to promulgate the 
    Cr+6 rule focused on data regarding Cr+6 emissions from CCTs 
    (55 FR 222 at 224). A background document, ``Chromium Emissions from 
    Comfort Cooling Towers - Background Information for Proposed 
    Standards'' (EPA-450/3-87-010a), March 1, 1988 (OPTS 61012) described 
    EPA's regulatory alternatives and expected impacts. The information-
    gathering, analysis, and rulemaking were used solely to support a TSCA 
    section 6 determination regarding Cr+6-based water treatment 
    chemicals and not all possible Cr+6 mixtures and products. 
    Therefore, EPA believes that this amendment is consistent with the 
    originally intended scope and coverage of the TSCA section 6 
    regulations.
        The revised regulatory language clarifies that the chemicals 
    subject to the rule are any Cr+6 chemicals that can be used to 
    treat water, either alone or in combination with other chemicals, where 
    the mixture can be used to treat water. As stated above, the intended 
    effect of this change is to reduce the scope of the TSCA section 12(b) 
    export notifications that are triggered by Sec. 749.68.
        Currently, the section heading of Sec. 749.68 reads ``Hexavalent 
    chromium chemicals in comfort cooling towers.'' EPA believes that a 
    more appropriate focus and heading for the rule is ``Hexavalent 
    chromium-based water treatment chemicals in cooling systems,'' and is 
    therefore implementing this change. Also, because the term ``hexavalent 
    chromium chemicals'' in the current Sec. 749.68(d)(10) will no longer 
    be used, the definition is dropped.
        As discussed above, the TSCA section 12(b) export notification 
    requirements are triggered by the export of certain chemical substances 
    or mixtures that are the subjects of certain actions under TSCA, 
    including Cr+6 because of the section 6 Cr+6 rule. Currently, 
    Sec. 749.68(a) states:
    
        (a) Chemical substance subject to this section. Hexavalent 
    chromium, usually in the form of sodium dichromate (CAS No. 10588-
    01-9), is subject to this section.
    
        Today, Sec. 749.68(a) is amended to state:
    
        (a) Chemicals subject to this section. Hexavalent chromium-based 
    water treatment chemicals that contain hexavalent chromium, usually 
    in the form of sodium dichromate (CAS No. 10588-01-9), are subject 
    to this section. Other examples of hexavalent chromium compounds 
    that can be used to treat water are: Chromic acid (CAS No. 7738-94-
    5), chromium trioxide (CAS No. 1333-83-0), dichromic acid (CAS No. 
    13530-68-2), potassium chromate (CAS No. 7789-00-6), potassium 
    dichromate (CAS No. 7778-50-9), sodium chromate (CAS No. 7775-11-3), 
    zinc chromate (CAS No. 13530-65-9), zinc chromate hydroxide (CAS No. 
    153936-94-6), zinc dichromate (CAS No. 14018-95-2), and zinc 
    potassium chromate (CAS No. 11103-86-9).
    
        By instituting this amendment in conjunction with the other changes 
    discussed herein, especially those at Sec. 749.68(d)(11) (see below), 
    EPA intends that only Cr+6 compounds which can be used to treat 
    water, either alone or in combination with other chemicals, where the 
    mixture can be used to treat water, would be subject to the rule and 
    thus the section 12(b) export notification requirements.
        Related to this change, EPA is amending certain language in 
    Sec. 749.68(b), entitled ``Purpose,'' and Sec. 749.68(c), entitled 
    ``Applicability,'' to reflect the changed focus of the rule from 
    Cr+6 to Cr+6-based water treatment chemicals. Refer to 
    Sec. 749.68(b) and (c) of the regulatory text for the revised language.
        EPA is also adding a chemical definition of Cr+6 in 
    Sec. 749.68(d)(10) to clarify the revised subject of the rule. The 
    definition of Cr+6 is now ``the oxidation state of chromium with 
    an oxidation number of +6; a coordination number of 4 and tetrahedral 
    geometry.''
        Another key change is a revised definition of ``hexavalent 
    chromium-based water treatment chemicals.'' The current definition in 
    Sec. 749.68(d)(11) states that ``hexavalent chromium-based water 
    treatment chemicals means any hexavalent chromium, alone or in 
    combination with other water treatment chemicals, used to treat 
    water.'' (emphasis added). The amended definition states that 
    ``hexavalent chromium-based water treatment chemicals means any 
    chemical containing hexavalent chromium which can be used to treat 
    water, either alone or in combination with other chemicals, where the 
    mixture can be used to treat water.'' (emphasis added). This change is 
    intended to require export notification for the export of chemicals 
    that can be used to treat water, whether or not they are actually used 
    to treat water. EPA believes that exporters will not always know the 
    actual end use of the Cr+6 product. However, EPA believes that 
    exporters are likely to know potential end uses or how Cr+6 can be 
    used. Additionally, to help exporters identify which Cr+6 
    compounds can be used, either alone, or in combination with other 
    chemicals to treat water, the Agency is listing examples of such 
    compounds. This change is not intended to have any effect on the 
    current labeling requirements or the prohibitions of the Cr+6 
    rule.
        In order that the labeling requirements will not be affected by the 
    changes being made today, EPA is changing the language of 
    Sec. 749.68(g). Currently, the labeling requirement at Sec. 749.68(g) 
    states:
    
        Labeling. (1) Each person who distributes in commerce hexavalent 
    chromium-based water treatment chemicals after February 20, 1990, 
    shall affix a label. . .
    
        As the current definition of ``hexavalent chromium-based water 
    treatment chemicals'' in Sec. 749.68(d)(11) is ``any hexavalent 
    chromium, alone or in combination with other water treatment chemicals, 
    used to treat water,'' (emphasis added) labeling is required only for 
    hexavalent chromium-based water treatment chemicals used to treat 
    water. As stated above, the new definition of ``hexavalent chromium-
    based water treatment chemicals'' in Sec. 749.68(d)(11) is ``any 
    hexavalent chromium which can be used to treat water. . .'' (emphasis 
    added). Without changing Sec. 749.68(g), this new definition would have 
    the effect of expanding the labeling requirements to require labeling 
    of any hexavalent chromium, either alone or in combination with other 
    chemicals, that can be used to treat water, where the mixture can be 
    used to treat water. However, as the intent of this amendment is not to 
    change the scope of the labeling requirements, the phrase ``for use in 
    cooling systems'' is being added to Sec. 749.68(g). This section now 
    reads:
        (g) Labeling. (1) Each person who distributes in commerce 
    hexavalent chromium-based water treatment chemicals for use in 
    cooling systems after February 20, 1990, shall affix a label. . .
    
    EPA believes this change, along with the other modifications, will have 
    the effect of maintaining the current labeling requirements.
        All of the changes are meant to reduce the scope of TSCA section 
    12(b) export notifications without affecting the prohibitions and 
    labeling requirements in the current rule. With today's amendment, EPA 
    intends that exporters of paints, dyes, pigments, electroplating and 
    conversion coating products, and other products containing Cr+6 
    that cannot be used to treat water will not report the export to EPA 
    under TSCA section 12(b). To accomplish this, EPA is amending certain 
    definitions and other appropriate provisions of the Cr+6 rule as 
    discussed above. EPA believes that today's rule will reduce the burden 
    on the regulated community in cases where export notification provides 
    little or no benefit to importing countries.
        Today's rule is consistent with other Agency efforts to improve the 
    utility of these notices for receiving governments, and to optimize the 
    ability of EPA to process more efficiently export notices it receives 
    annually and respond to requests from foreign governments for 
    additional information on chemicals and export notices. For example, on 
    July 21, 1981 (46 FR 37608), in its notice on ``Asbestos Export 
    Notification,'' EPA clarified the reporting responsibilities of persons 
    exporting asbestos or mixtures containing asbestos by defining which 
    types of asbestos require export notification. As another example, on 
    July 27, 1993 (58 FR 40238), in a Federal Register document entitled 
    ``Export Notification Requirement; Change to Reporting Requirements; 
    Final Rule,'' EPA issued a rule that changed the current annual 
    notification requirements for exporters of chemical substances and 
    mixtures subject to TSCA section 4 test rules or consent orders to a 
    one-time (instead of annual) export notification per chemical per 
    importing country.
        EPA believes that such actions, and today's action, will enhance 
    other governments' ability to thoughtfully consider notices received 
    under TSCA section 12(b) and react appropriately to chemicals being 
    imported by focusing export notifications on a more defined set of 
    chemicals that EPA has identified for regulatory action. As EPA stated 
    in the preamble to the final export notification rule, ``[t]he intended 
    focus of the notice to foreign governments is the chemical substance or 
    mixture and what EPA has done or found out about it. . . .'' (45 FR 
    82844, December 16, 1980). Since the primary purpose of TSCA section 
    12(b) export notification is to alert and inform other governments of 
    hazards that may be associated with a chemical substance or mixture, it 
    is important that the export notification requirements are implemented 
    in a manner that efficiently conveys EPA's concerns. EPA believes that 
    today's amendment will increase the efficiency of the operation of the 
    section 12(b) requirement as applied to the Cr+6 rule by 
    eliminating the current export notifications associated with the export 
    of Cr+6 chemicals that cannot be used to treat water.
    
    V. Significant Comments on the Proposed Rule
    
        One commenter requested that EPA expressly mention electroplating 
    and conversion coating products among the examples of products excluded 
    from the TSCA section 12(b) notification requirement. Based on a 
    technical evaluation of this request, in appropriate sections of the 
    preamble of this final rule, EPA is adding electroplating and 
    conversion coating products as examples of products excluded from the 
    export notification requirement because these products containing 
    hexavalent chromium cannot be used to treat water. However, EPA does 
    not intend that the listing of specific examples should exclude any 
    other products that cannot be used to treat water.
        A second comment was that EPA revise the definition of ``hexavalent 
    chromium-based water treatment chemicals'' to encompass only hexavalent 
    chromium ``intended'' for use in treating water, not that which ``can 
    be'' so used. EPA considered the option of substituting hexavalent 
    chromium ``intended'' for use in treating water for the proposed ``can 
    be used'' in the definition of ``hexavalent chromium-based water 
    treatment chemicals,'' but has decided against such substitution. EPA 
    believes it could be extremely difficult to determine the exporter's 
    intent regarding use of an exported product. It is difficult to 
    determine the ``intent'' of a manufacturer in exporting a substance or 
    mixture. However, even if the intent of the exporter could be 
    determined as not including water treatment uses, once the substance or 
    mixture is imported into the foreign country, it could be used for a 
    water treatment purpose not withstanding the intent of the exporter. 
    Retaining the ``can be used'' definition helps to ensure that foreign 
    countries receive notice of the import of substances or mixtures that 
    could be of concern.
        Another comment suggested adopting a de minimis and impurity 
    exclusion for the export of section 12(b) substances. EPA currently 
    requires export notification for any section 12(b) substance present in 
    mixtures, excluding articles other than PCB articles, at any 
    concentration and regardless of whether it is intentionally present in 
    the mixture or is present as an impurity. The suggestion made by the 
    commenter is outside the scope of this rulemaking. However, as stated 
    in the preamble to a final amendment made to the export notification 
    rule in the Federal Register of July 27, 1993 (58 FR 40238), EPA may 
    examine additional approaches modifying the section 12(b) export 
    notification program in the future.
        Finally, one commenter requested that EPA publish a formal 12(b) 
    list in the Code of Federal Regulations (CFR), which would include 
    effective and sunset (termination) dates. Because section 12(b) export 
    notification is required only for substances that are the subject of 
    certain regulatory actions taken under TSCA section 4, 5, 6, or 7, EPA 
    believes the notice associated with publication of these underlying 
    actions in the Federal Register is sufficient for purposes of section 
    12(b). Moreover, the notices initiating these underlying actions 
    generally include a specific discussion of obligations triggered under 
    12(b). Section 12(b) of TSCA requires no additional rulemaking, 
    separate from the underlying actions, to trigger the export 
    notification requirements. For final rules and orders, effective dates 
    for the 12(b) requirements are the same as the effective dates of the 
    underlying actions. In cases where the proposed actions prompt the 
    section 12(b) export notifications, the requirement to submit export 
    notifications begins 30 days after publication of the proposal in the 
    Federal Register. See 40 CFR 707.65(b). Sunset dates (i.e., dates that 
    certain requirements terminate) for purpose of TSCA section 12(b) apply 
    only where the underlying requirement prompting the export 
    notifications are TSCA section 4 or 5(b) actions. As stated in the 
    preamble to the TSCA section 12(b) Export Notification Rule amendments 
    in the Federal Register of July 27, 1993 (58 FR 40238), these sunset 
    dates coincide with the expiration of the test data reimbursement 
    period as defined at 40 CFR 790.3. In the near future, EPA plans to 
    issue a Federal Register notice listing test data reimbursement period 
    expiration dates for certain TSCA section 4 substances.
        As recognized by the commenter, EPA currently makes available an 
    informal list of substances subject to section 12(b) export 
    notification that is updated on or about a quarterly basis. Although 
    inadvertent omission from this section 12(b) list does not excuse non-
    compliance with the statutory requirements of section 12(b), EPA 
    believes it does serve as a valuable compliance aid. In light of the 
    above, EPA believes that publication of the section 12(b) list in the 
    CFR is not warranted at the present time.
    
    VI. Confidentiality
    
        A person may assert a claim of confidentiality for any information, 
    submitted to EPA in connection with this rule. Any claim of 
    confidentiality must accompany the information so claimed when it is 
    submitted to EPA. Persons must mark information claimed as confidential 
    by circling, bracketing, or underlining it, and marking it with 
    ``CONFIDENTIAL'' or some other appropriate designation. EPA will 
    disclose information subject to a claim of confidentiality only to the 
    extent permitted by section 14 of TSCA and 40 CFR part 2, Subpart B. If 
    a person does not assert a claim of confidentiality for information at 
    the time it is submitted to EPA, EPA may make the information public 
    without further notice to that person.
    
    VII. Economic Impact
    
        In a support document entitled Economic Analysis of the Amendment 
    to the TSCA Section 6 Rule for Hexavalent Chromium, dated April 1994, 
    EPA has evaluated potential changes in costs to the Cr+6 rule that 
    would be associated with these amendments. The total savings to 
    industry and EPA associated with this amendment are estimated to be 
    $5,400 to $16,300 per year. EPA's complete economic analysis is 
    available in the public record for this rule (OPPTS-61018).
    
    VIII. Rulemaking Record
    
        EPA has established a record for this rulemaking (docket number 
    OPPTS 61018A). The record includes basic information considered by EPA 
    in developing this rule. EPA has supplemented the record with all 
    written comments and additional information as it was received. In 
    addition to the proposed rule (58 FR 63148, November 30, 1993) and 
    comments received on the proposal, the record now includes the

    IX. Regulatory Assessment Requirements
    
    A. Executive Order 12866
    
        Under Executive Order 12866, (58 FR 51735, October 4, 1993), the 
    Agency must determine whether the regulatory action is ``significant'' 
    and therefore subject to review by the Office of Management and Budget 
    (OMB) and the requirements of the Executive Order. Under section 3(f), 
    the order defines a ``significant regulatory action'' as an action that 
    is likely to result in a rule (1) having an annual effect on the 
    economy of $100 million or more, or adversely and materially affecting 
    a sector of the economy, productivity, competition, jobs, the 
    environment, public health or safety, or State, local or tribal 
    governments or communities (also referred to as ``economically 
    significant''); (2) creating serious inconsistency or otherwise 
    interfering with an action taken or planned by another agency; (3) 
    materially altering the budgetary impacts of entitlement, grants, user 
    fees, or loan programs or the rights and obligations of recipients 
    thereof; or (4) raising novel legal or policy issues arising out of 
    legal mandates, the President's priorities, or the principles set forth 
    in this Executive Order. Pursuant to the terms of this Executive Order, 
    it has been determined that this rule is not ``significant'' and is 
    therefore not subject to OMB review.
    
    B. Regulatory Flexibility Act
    
        Under the Regulatory Flexibility Act (5 U.S.C. 605(b)), EPA has 
    determined that this rule does not have a significant impact on a 
    substantial number of small businesses. This rule actually decreases 
    the reporting burden for small businesses that export Cr+6 
    chemicals that cannot be used for water treatment, which are currently 
    subject to the reporting requirements of TSCA section 12(b). This rule 
    would not add any economic burden to small businesses. Pursuant to 
    section 605(b) of the Regulatory Flexibility Act, 5 U.S.C. 605(b), EPA 
    certifies that this rule will not have a significant economic impact on 
    small businesses.
    
    C. Paperwork Reduction Act
    
        OMB has approved the information collection requirements contained 
    in the Cr+6 Rule at 40 CFR part 749, subpart D under the 
    provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), and 
    has assigned OMB control number 2060-0193 to that collection activity. 
    In addition, OMB has also approved the information collection 
    requirements contained in the Export Notification Rule at 40 CFR part 
    707, subpart D under the provisions of the Paperwork Reduction Act, and 
    has assigned OMB control number 2070-0030 to that activity.
        The changes in this rule are not expected to impact the information 
    collection requirements contained in the Cr+6 Rule at 40 CFR part 
    749, subpart D, and EPA does not expect to change the burden estimates 
    approved by OMB under OMB control number 2060-0193. However, since the 
    rule amends the applicability of the information collection 
    requirements contained in the Export Notification Rule at 40 CFR part 
    707, subpart D, EPA expects to change the burden estimates approved 
    under OMB control number 2070-0030, and upon the signature of this 
    final rule, will submit an information correction worksheet.
        The rule will reduce the number of export notices required from the 
    public by approximately 237 submissions per year. Public reporting 
    burden for the collection of information under 40 CFR part 707, 
    ``Chemical Imports and Exports,'' is estimated to average .5 to 1.5 
    hours per response, including time for reviewing instructions, 
    searching existing data sources, gathering and maintaining the data 
    needed, and completing and reviewing the collection of information. 
    Total public reporting burden is expected to decrease as a result of 
    this rule by approximately 119 to 356 hours per year.

    Carol M. Browner,
    Administrator.
    
        Therefore, 40 CFR part 749 is amended as follows:
    
    PART 749--[AMENDED]
    
        1. The authority citation for part 749 continues to read as 
    follows:
    
        Authority: 15 U.S.C. 2605 and 2607.
    
        2. In Sec. 749.68, by revising the section heading, paragraphs (a), 
    (b), (c), (d)(10), (d)(11), and (g)(1) to read as follows:
    
    
    Sec. 749.68   Hexavalent chromium-based water treatment chemicals in 
    cooling systems.
    
        (a) Chemicals subject to this section. Hexavalent chromium-based 
    water treatment chemicals that contain hexavalent chromium, usually in 
    the form of sodium dichromate (CAS No. 10588-01-9), are subject to this 
    section. Other examples of hexavalent chromium compounds that can be 
    used to treat water are: Chromic acid (CAS No. 7738-94-5), chromium 
    trioxide (CAS No. 1333-83-0), dichromic acid (CAS No.13530-68-2), 
    potassium chromate (CAS No. 7789-00-6), potassium dichromate (CAS No. 
    7778-50-9), sodium chromate (CAS No. 7775-11-3), zinc chromate (CAS No. 
    13530-65-9), zinc chromate hydroxide (CAS No. 153936-94-6), zinc 
    dichromate (CAS No. 14018-95-2), and zinc potassium chromate (CAS No. 
    11103-86-9).
        (b) Purpose. The purpose of this section is to impose certain 
    requirements on activities involving hexavalent chromium-based water 
    treatment chemicals to prevent unreasonable risks associated with human 
    exposure to air emissions of hexavalent chromium from comfort cooling 
    towers.
        (c) Applicability. This section is applicable to use of hexavalent 
    chromium-based water treatment chemicals in comfort cooling towers and 
    to distribution in commerce of hexavalent chromium-based water 
    treatment chemicals for use in cooling systems.
        (d)  *  *  *
        (10) Hexavalent chromium means the oxidation state of chromium with 
    an oxidation number of +6; a coordination number of 4 and tetrahedral 
    geometry.
        (11) Hexavalent chromium-based water treatment chemicals means any 
    chemical containing hexavalent chromium which can be used to treat 
    water, either alone or in combination with other chemicals, where the 
    mixture can be used to treat water.
          *      *      *      *      *
        (g) Labeling. (1) Each person who distributes in commerce 
    hexavalent chromium-based water treatment chemicals for use in cooling 
    systems after February 20, 1990, shall affix a label or keep affixed an 
    existing label in accordance with this paragraph, to each container of 
    the chemicals. The label shall consist of the following language:
    
        WARNING: This product contains hexavalent chromium. Inhalation 
    of hexavalent chromium air emissions increases the risk of lung 
    cancer. Federal Law prohibits use of this substance in comfort 
    cooling towers, which are towers that are open water recirculation 
    devices and that are dedicated exclusively to, and are an integral 
    part of, heating, ventilation, and air conditioning or refrigeration 
    systems.
    
          *      *      *      *      *
