**Final Clarification for Chemical Identification Describing Activated**  **Phosphors for TSCA Inventory Purposes** 

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Final clarification.

**SUMMARY :**  This is a clarification under which certain activated phosphors that
are not on the Toxic Substances Control Act (TSCA) section 8(b) Chemical Substance Inventory (TSCA Inventory)
will be considered to be new chemical substances under TSCA section 5, and thus will be subject to applicable notification requirements under TSCA
section 5. In certain letters and other statements issued by EPA from 1978 to 2003, the Agency erroneously indicated that activated phosphors (otherwise known as doped phosphors) constitute mixtures of phosphors and dopants for purposes of the TSCA Inventory, and thus that they were not separately reportable as chemical substances under TSCA section 5(a) new chemical notification requirements. This clarification is necessary because EPA’s
statements in this area have not been

consistent. **DATES :**  EPA’s clarification is effective August 24, 2011.

. II. Background

A. What Action is the Agency Taking?

EPA is clarifying that certain previous
EPA statements which indicated that activated phosphors are mixtures rather
than chemical substances in their own right were erroneous, and that TSCA Inventory listing may be required for these materials. This action provides a clarification in the approach used for
the chemical identification of activated (doped) phosphors for purposes of listing on the TSCA Inventory. This clarification was proposed in the Federal Register issue of January 16, 2008 (73 FR 2854) (FRL–8131–8) and a reopening of comments on the proposed
clarification was announced in the Federal Register issue of May 2, 2008 (73 FR 24187) (FRL–8360–7).

An activated phosphor is a substance resulting from the chemical
combination of a mixture of metal oxides, carbonates, phosphates or acid phosphates, chlorides, and/or fluorides, most frequently by sintering, along with a small amount of one or more dopants. Dopants can include such substances as


### 8267 Federal Register / Vol. 75, No. 36 / Wednesday, February 24, 2010 / Rules and Regulations

yttrium, europium, germanium, gallium, strontium, antimony, manganese, or magnesium. When an activated phosphor is electrically excited, it emits light. The color and electrical efficiency of light emission is a function of the parent phosphor and of the dopant which is present.

EPA is required under TSCA section 8(b), 15 U.S.C. 2607(b), to compile and keep current an inventory of chemical substances manufactured (which includes import) or processed for commercial purposes in the United States. This inventory is known as the TSCA Chemical Substance Inventory (TSCA Inventory). EPA promulgated a
rule in the Federal Register issue of December 23, 1977 (42 FR 64572) under TSCA section 8(a), 15 U.S.C. 2607(a), to compile an inventory of chemical
substances in commerce at that time. Building on several earlier interim policies, EPA promulgated a rule in the Federal Register issue of May 13, 1983 (48 FR 21722) setting forth procedures for the submission, receipt, and health and safety review of PMNs covering chemical substances not yet in commerce when required under TSCA section 5, 15 U.S.C. 2604. Section 8(b)(1) of TSCA, 15 U.S.C. 2607(b)(1),
instructs EPA to add a PMN substance to the TSCA Inventory as of the earliest
date on which it is manufactured or processed in the United States.

Manufacture of a non-exempt new chemical substance is prohibited prior to the expiration of the new chemical notice review period. Once EPA receives a PMN, the Agency has 90 days to review the notice (unless for good cause EPA extends the review period); the Agency has 30 or 45 days to complete its review of exemption requests. During the review period, EPA may act under TSCA section 5(e) or 5(f) to regulate the new chemical substance. If EPA has not prohibited manufacture of the chemical substance during the review period, manufacture may begin subject to any restrictions or testing requirements imposed upon the submitter during the review period (these restrictions may be imposed upon others via a Significant New Use Rule (SNUR) and subsequent action under TSCA section 5(e) or 5(f) taken in follow-up to a significant new use notification (SNUN)). When manufacture begins, the notice submitter must provide a Notice of
Commencement of Manufacture or Import (NOC), after which EPA adds the
chemical substance to the TSCA Inventory. If the Agency receives a new
chemical notice submission for a
chemical substance which EPA
determines is excluded from consideration as a chemical substance under TSCA (generally because it meets the criteria for one of the excepted categories at TSCA section 3(2)(B), which include mixtures, pesticides, tobacco, food, drugs, etc.) the Agency will not accept the new chemical notice. Similarly, during the period 1978–1979, when EPA was accepting submissions for the Initial TSCA Inventory, and during 1979–1983, prior to promulgation of the May 13, 1983 PMN rule, the Agency rejected notifications
for materials which it determined to be
excluded.

B. Why is the Agency Taking this

Action?

Partly as a result of the Agency’s incomplete information and understanding of the chemistry involved in manufacturing activated phosphors, from 1978 through 2003,

EPA was inconsistent in its statements to potential submitters and in its actions regarding whether activated phosphors
are considered distinct chemical substances for purposes of the TSCA Inventory. During the period 1978– 1979, when EPA received submissions for the Initial TSCA Inventory, it accepted many doped phosphors for listing, but in some cases it sent

‘‘ problem letters ’’ to the manufacturers of doped phosphors indicating that they were mixtures of the phosphor and dopants and thus ineligible for listing.

In October 1979, the Agency wrote to a lighting manufacturer and stated that such listings could be ‘‘unnecessary’’
and that their continued inclusion on the TSCA Inventory would be ‘‘ closely
examined. ’’ In January 1980, a lighting manufacturer wrote to the Agency to challenge problem letters it had
received. The manufacturer stated that
the materials it manufactured should be
excluded from mixture status because they had characteristic crystal structures and that volatile reaction products given off during their manufacture showed that chemical synthesis was occurring. In March 1982, the Agency wrote to a lighting manufacturer and suggested that certain chlorophosphate activated phosphors could be regarded either as physically altered chlorophosphates or as mixtures, thus not subject to premanufacture notice. In August 1983, the Agency wrote to the lighting manufacturer which had challenged the problem letters and informed it that the materials had, in fact, been placed on the TSCA Inventory, and in addition
that a new chemical notice was appropriate for another activated phosphor but that ‘low levels’ of an activator would not require a separate
new chemical notice. In January 1993, a lighting
manufacturer submitted a Low Volume Exemption (LVE) Application for an activated phosphor with a letter referencing much of the history as
described in this document and asserting that, based on Agency positions, no submission should be necessary, but the Agency did accept the application and granted the LVE. After that LVE was granted, the
manufacturer submitted a letter asserting that activated phosphors should, in fact, be considered to be mixtures and requested that the Agency issue a clarifying statement. In response, the Agency met with the manufacturer
on the issue and indicated that activated phosphors should be considered
chemical substances instead of mixtures, but did not issue a written
clarification.

In 1995, EPA issued the publication
entitled ‘‘ Toxic Substances Control Act Inventory Representation for Products Containing Two or More Substances: Formulated and Statutory Mixtures (Formulated and Statutory Mixtures), ’’
available at http://www.epa.gov/ opptintr/newchems/pubs/mixtures.txt), which provided guidance regarding the mixture definition given at 40 CFR 710.2(q) and 720.3(u):

Mixture means any combination of two or
more chemical substances if the combination does not occur in nature and is not, in whole or in part, the result of a chemical reaction; except ‘‘mixture ’’ does include (1) any combination which occurs, in whole or in part, as a result of a chemical reaction if the
combination could have been manufactured for commercial purposes without a chemical
reaction at the time the chemical substances comprising the combination were combined,
and if all of the chemical substances comprising the combination are not new chemical substances, and (2) hydrates of a chemical substance or hydrated ions formed by association of a chemical substance with

water.

‘‘ Formulated and Statutory Mixtures ’’ discusses common examples of mixtures, including paints, blended fuels, and solvent combinations.

‘‘Mixture ’’ can include, as well, solid solutions—homogeneous crystalline phases composed of several distinct chemical species. Alloys are solid solutions, and are considered mixtures.For the purposes of TSCA, multicomponent blends or formulations of chemical substances, or certain reaction product combinations which can be completely characterized as consistently
formed definite sets of their constituent chemical substances, are considered to
be mixtures of chemical substances. Mixtures are not reportable, although
their constituent chemical substances are. Most important in the context of


### 8268 Federal Register / Vol. 75, No. 36 / Wednesday, February 24, 2010 / Rules and Regulations

this document, a mixture can often provide its function over some range of constituent ratios, consequently it is
unusual if the ratios of chemical substances which comprise a mixture are necessarily definite or stoichiometric, and if the mixture components are deliberately reacted together to manufacture a chemical substance, EPA does not consider this reaction product to be a mixture for TSCA purposes except in very specialized circumstances which are not present in the case of the activated phosphors.

In June 1998, a lighting manufacturer wrote to the Agency and stated that, in the absence of any negative response by the Agency within 60 days of the letter, it intended to rely on its interpretation
of ‘‘ Formulated and Statutory Mixtures, ’’
and that it believed that that interpretation precluded TSCA Inventory listing for activated phosphors. The Agency did not respond to that letter. Based on a 2003 request from a lighting manufacturer, and cognizant of the history described in this document, EPA held a meeting with the manufacturer in September 2003
and as a result has reexamined some earlier assumptions—particularly about non-stoichiometry and non-reaction
between chemical substances used to make activated phosphors—which may
have led it to believe that activated phosphors could be considered

mixtures.

The result of this reexamination is this clarification that EPA generally considers activated phosphors to be
distinct chemical substances under
TSCA. EPA’s clarification on the potential need to report activated phosphor materials is based on its updated understanding about reaction characteristics and stoichiometry in activated phosphor manufacture: Activated phosphors are in general synthesized by means of a solid state reaction at high temperature and typically using precise quantities of the precursor chemical substances, both for the base materials and for the dopants which control the quality of light emitted. Precise ratios of component
materials are used to maintain strict stoichiometry in the end product, and component materials are thoroughly blended before reaction for uniformity of the product. Heat may be absorbed or released by the reactant mixture at certain temperatures, typically by the release of water; this is often an
indication of chemical substance synthesis. During the manufacture of activated phosphors, other volatile reaction products are often emitted,
another indication that chemical substances are being formed. The phosphor and the amount of dopant added need to be controlled with high precision, and during sintering the doped phosphor undergoes oxidation state changes. Each of these reaction characteristics is a strong indication that a chemical substance is being synthesized. Since most or all of these characteristics are generally present in activated phosphor manufacture, EPA believes that activated phosphors are manufactured for commercial purposes with chemical reaction. Additionally, activated phosphor products have a
different function from the material which would be produced by the same synthetic process in the absence of dopant, and which would not emit the characteristic light, which is the primary property sought. Because dopants provide the primary property sought from these materials, small or even trace amounts of dopant are
considered to be reactants which must be included in the chemical identity. Therefore, in EPA’s view these materials

are not ‘‘mixtures ’’ of phosphors and dopants.

C. Why is this Chemical Identity Clarification Necessary?

Because EPA does not view activated phosphors as mixtures, some previous EPA statements that such materials may not need to be reviewed through the new chemicals process were incorrect. As a result of certain past EPA statements, some manufacturers of activated phosphors have not submitted
new chemical notices under TSCA
section 5 because those statements incorrectly indicated that activated phosphors were covered for TSCA purposes if the phosphors and activators were already on the TSCA Inventory.
Other manufacturers have submitted
new chemical notices for similar materials, and they have generally been given TSCA Inventory listings. Several industry representatives have asked EPA to clarify the Agency’s chemical identity policy for activated phosphors. EPA now agrees that it is necessary to add listings to the TSCA Inventory for activated phosphors which have been
manufactured but not listed. This document provides a clarification to previous statements on chemical identity for activated phosphors. On the effective date of this clarification, activated phosphors that are not on the TSCA Inventory will be considered new
chemical substances under TSCA

section 5.

Because some of the statements provided by the Agency prior to 2003
led some manufacturers to believe that the products they manufactured were already on the TSCA Inventory if the phosphors and activators were on the TSCA Inventory, some manufacturers of activated phosphor products have not
submitted new chemical notices required under TSCA section 5. This chemical identification problem is similar to one involving monomer acid and its derivatives, which was resolved through Agency-industry dialog and a period for submission of new chemical notices (Correction to Chemical
Nomenclature for Monomer Acid and Derivatives for TSCA Inventory Purpose published in the Federal Register issue of June 27, 2001 (66 FR 34193) (FRL– 6784–6)). The Agency is addressing this activated phosphor situation in a similar

manner. III. Activated Phosphors Under the TSCA Inventory and Implications for TSCA Section 5 Reporting

EPA is clarifying that those of EPA’s
earlier statements which indicated that activated phosphors are mixtures rather
than chemical substances in their own right were erroneous, and that TSCA Inventory listing or TSCA section 5(h)(4) exemption will be required for
these materials. Pursuant to TSCA section 5(a)(1), 15 U.S.C. 2604(a)(1), new chemical notices will be required for activated phosphors not on the TSCA Inventory (and for which a TSCA section 5(h)(4) exemption has not been granted) and which are manufactured
on or after the effective date of the clarification. See EPA PMN regulations at 40 CFR part 720 for details regarding when reporting is required. Consistent with TSCA Inventory correction guidelines published in the Federal Register issue of July 29, 1980 (45 FR 50544), EPA does not consider activated phosphors that were never reported for the Initial TSCA Inventory to be eligible for TSCA Inventory correction as an
alternative to new chemical notice
submission.

A. What are the Nature and Scope of this Clarification?

EPA does not believe that activated phosphors are mixtures rather than chemical substances in their own right. Thus listing on the TSCA Inventory established under TSCA section 8(b) may be required for these chemical
substances. This clarification will affect anyone who manufactures, or who plans to manufacture, an activated phosphor not currently listed on the TSCA Inventory and for a TSCA-covered use.

B. What are the Key Dates and Provisions of this Clarification?

The effective date for this clarification, described in Unit II.B., will


### 8269 Federal Register / Vol. 75, No. 36 / Wednesday, February 24, 2010 / Rules and Regulations

be 18 months after date of publication
of this final document in the Federal Register . After the effective date, any person manufacturing an activated phosphor for a non-exempt commercial purposes and who has not met the new chemical substances requirements of
TSCA section 5 will not be considered in compliance with TSCA. By that date, companies required to submit PMNs or exemption notices must have done so at least 90 days (for PMNs, less for exemption notices) before the effective date, to ensure that Agency review is completed before this clarification takes
effect.

By that date, companies required to submit premanufacture notices or exemption applications must have done so at least 90 days (for PMNs, less for exemption applications) before the effective date, to ensure that Agency review is completed before this
clarification takes effect. New chemical notice review may entail suspension of the notice review period (either by EPA or at the request of the submitter). If a new chemical notice seeking an exemption is rejected, a PMN may need to be filed. Because manufacture may not continue after the 18–month period provided in this notice, companies are advised to submit any required new
chemical notices well before the
effective date to ensure that all issues are resolved in a timely fashion.

EPA will work closely with
manufacturers to resolve chemical identity issues for any specific material
that the manufacturer believes should
be viewed as a mixture.

To facilitate the new chemical notice process for activated phosphors currently being manufactured but which are not listed on the TSCA Inventory as distinct chemical substances, EPA will allow an exception to its TSCA new chemicals program policy limit of six chemical substances per consolidation
notice for these chemical substances. EPA encourages persons intending to manufacture activated phosphors to file new chemical notices using the proper chemical identity immediately instead of delaying their submissions to near the
effective date of this document.

New chemical notices filed in response to this chemical identification clarification shall, as specified in 40 CFR 720.50, include all information normally included with a new chemical notice submission, such as toxicity data
on the chemical substance that are in the possession or control of the notice submitter, or known to or reasonably ascertainable by the notice submitter. C. Will a New Chemical Notice Be Required for Persons Who Did Not
Submit One Due to an Incorrect EPA Statement, Regardless of Whether They Still Manufacture the Chemical
Substance?

Where required by TSCA section 5 and in accordance with 40 CFR part 720, a new chemical notice must have been submitted for any manufacture for a non-exempt commercial purpose that takes place on or after August 24, 2011.
No new chemical notice need be submitted for manufacture taking place before that date. For example, if you manufactured such a phosphor in 1986 but will not be resuming manufacture after August 24, 2011, you are not required to submit a new chemical notice at this time. However, if you later
form an intention to manufacture the activated phosphor on or after the
effective date of this clarification and
the chemical substance has not in the interim been placed on the TSCA Inventory due to another company’s manufacture or import, you will need to submit a new chemical notice (and the review period must be completed) before commencing manufacture. Activated phosphors manufactured before August 24, 2011 can be used or processed after the effective date,
whether a new chemical notice has been
filed or not.

D. Discussion of Public Comments on the Proposed Clarification

The Agency reviewed and considered
the comments submitted on the proposed clarification published in the Federal Register issue of January 16, 2008. Copies of all submitted comments
are available in the docket for this

action.

1. Comment . Commenter OSRAM Sylvania questions the Agency’s authority for requiring new chemical reporting for chemical substances that have been in production for some time.
The commenter states that ‘‘EPA lacks the authority to extend the scope of the TSCA Inventory and PMN requirements to the regulations of these existing
chemicals. ’’ The commenter suggests that the Agency use TSCA Inventory correction procedures to deal with activated phosphors, and argues that the clarification as to the TSCA Inventory status of activated phosphors constitutes rulemaking, as ‘‘ it would impose new, substantive legal obligations upon a class of chemicals and companies. ’’

Response . EPA disagrees with the comment. TSCA section 3(2) defines

‘‘ chemical substance ’’ in relevant part as

‘‘ any organic or inorganic substance of a particular molecular identity. ’’ Two chemicals with differing molecular
identities are therefore considered
different chemical substances under TSCA. TSCA section 3(9) defines a ‘‘new chemical substance ’’ as ‘‘ any chemical
substance which is not included in the chemical substance list compiled and published under section 2607(b) of this
title ’’ (i.e., the TSCA Inventory). TSCA section 5(a)(1) applies PMN reporting requirements (or applicable exemptions) to new chemical substances. Thus, regardless of the fact that an activated phosphor may have been in commerce for years, if it has not been reported for the TSCA Inventory or added to the TSCA Inventory via PMN and NOC per 40 CFR part 720, it constitutes a new chemical substance subject to TSCA

section 5.

This clarification does not create obligations under TSCA. Requirements for new chemical notice reporting are self-executing in TSCA, flowing from TSCA section 5(a)(1) (with ‘‘ chemical
substance ’’ being defined in TSCA section 3(2) and ‘‘mixture ’’ defined in TSCA section 3(8)). The purpose of this document is simply to provide notice of
how EPA intends to enforce these provisions with respect to activated phosphors. EPA does not believe that this action constitutes rulemaking, but if it were rulemaking it would be interpretive rulemaking not subject to
notice and comment under the Administrative Procedure Act (APA).

The TSCA Inventory correction guidelines published in the Federal Register issue of July 29, 1980 indicate that materials that were never reported for the Initial TSCA Inventory are not eligible for TSCA Inventory correction as an alternative to premanufacture notice submission. The guidelines describe three main categories as appropriate for correction: Corrections to the identity of previously reported materials, corrections identifying previously unrecognized isolated intermediates, and corrections made in response to Agency communications which identify reporting errors and request corrections. For the first category, the TSCA Inventory correction procedures are appropriate when errors may have been made in reporting the identity ( ‘‘ (1) corrections of typographical or transcriptional errors in recording chemical identity on the Inventory reporting forms.. ’’ ) or when new information improving a previously reported identity can be developed because improvements in analytical methods and equipment regarding a previously reported chemical substance indicate that the accurate description of
the chemical substance is different from what was previously reported ( ‘‘ (2)


### 8270 Federal Register / Vol. 75, No. 36 / Wednesday, February 24, 2010 / Rules and Regulations

refinement of the identity of a reported substance, e.g., by narrowing the range of the values for a polymer; (3) identification of new components in the material, e.g., finding that a chemical substance reported as A is actually a mixture of A and B; and (4) discovery
that a chemical substance is different from that reported previously, e.g., determining that a substance reported as A is actually C or that a substance reported as D is actually a mixture of E
and F. ’’ ) Manufacturers’ failure to report activated phosphors for the TSCA Inventory under the first category is covered by none of the four eligibility criteria listed in this unit, which cover improved information about a previously reported chemical rather than failure to report it. Neither the second nor the third category is applicable here.

Under these guidelines, a blanket
exclusion from TSCA section 5 reporting, and inclusion on the TSCA Inventory by correction, for all activated phosphors including those first manufactured subsequent to the reporting period for the Initial TSCA Inventory, would be inappropriate. EPA
believes such an exclusion would prevent these materials from receiving the environmental, workplace safety, and consumer safety review contemplated by TSCA.

2. Comment . Commenter Color Pigment Manufacturers Association (CPMA) stated that because the EPA made its initial error in 1978, when materials were being entered into the TSCA Inventory by survey, EPA should allow for listing of the materials which are the subject of the action by survey and correction to the TSCA Inventory.

Response . CPMA has raised three
issues here: Addition to the TSCA Inventory by survey for materials which
were first manufactured before the end of the Initial TSCA Inventory reporting period, addition to the TSCA Inventory by survey for materials which were first
manufactured after the end of the Initial TSCA Inventory reporting period, and use of the TSCA Inventory correction
mechanism to enter non-TSCA Inventory materials onto the TSCA Inventory. CPMA’s comment provides no apparent rationale for allowing survey addition to the TSCA Inventory
for materials first manufactured after the Initial TSCA Inventory reporting closed in 1979. We have responded to the suggestion that the corrections procedure be used for activated phosphor materials in our response to the comment by OSRAM Sylvania, in

Unit III.D.1.

In regard to materials which were in commerce already before the end of the Initial TSCA Inventory reporting period in 1978, the Initial TSCA Inventory has been closed to survey reporting since the end of TSCA Inventory reporting in 1979, with the only mechanism for changing the Initial TSCA Inventory listings and compilation having been TSCA Inventory corrections. Although there may have been some persons manufacturing activated phosphors during the Initial TSCA Inventory reporting period for TSCA who were confused by EPA guidance at that time, irrespective of the guidance, those persons should have reported for the Initial TSCA Inventory in some manner
to account for their manufactured activated phosphor products. For example, in their Initial TSCA Inventory reporting, some persons may have identified their phosphor compounds without including the activators (dopants) in the chemical names. Others may have viewed their activated phosphors to be mixtures of two chemical substances (i.e., the activator and the phosphor host material), and reported both of their perceived mixture components.

EPA believes that a survey process for adding certain activated phosphors which may have been in commerce before 1978 to the TSCA Inventory at
this late date would not be warranted. TSCA section 5 reporting for all activated phosphors not on the TSCA Inventory (and for which a TSCA section 5(h)(4) exemption has not been granted) and which are to be
manufactured on or after the effective date of this clarification is a practical way to enable the affected manufacturers to come into compliance without undue disruption; it will facilitate the safety and environmental impact review for these materials intended in the statute; and the criteria
used to assess these materials will be
uniform.

3. Comment. Commenter American Chemistry Council (ACC) stated that this is more than a ’clarification’, but that it is a reversal of a position held for 20 years. Therefore, a public review and comment period, and consultation with stakeholders, is in order.

Response. Rather than having stated a consistent position, EPA’s guidance has been inconsistent, as noted in the proposal. This clarification provides the guidance necessary to go forward with one policy about the activated phosphor materials. A significant number of
manufacturers have in fact submitted PMNs and exemption notices covering over 200 activated phosphors (this includes reporting forms for the Initial TSCA Inventory) and the Initial TSCA Inventory reporting form and PMN substances have been given TSCA Inventory listings. The Agency has provided an opportunity for stakeholder input in the comment process via the proposed clarification, and met with
one manufacturer before the clarification was written and one during the comment period.

Most of the chemical substances subject to this clarification, and which are reportable, were manufactured after the close of the TSCA Inventory reporting period and new chemical
notices would have been submitted had there not been any erroneous guidance from EPA. Therefore, the net new chemical notice reporting burden should be little greater than if EPA had issued accurate guidance on activated phosphors after the publication of the Initial TSCA Inventory. Those who have already reported activated phosphors will not need to do anything, while those who have not yet reported such chemical substances must do so by the
effective date of this document. In this way, new chemical notices will finally
have been submitted for all of the activated phosphors initially manufactured for a non-exempt
commercial use. Due to the confusion caused by EPA’s earlier erroneous guidance, the Agency wishes to minimize any inconvenience to the chemical industry by providing an exception to its TSCA new chemicals program policy of a limit of six chemical substances per consolidation notice for these chemical substances and by setting an effective date for the consistent interpretation at 18 months after date of publication of this
document in the Federal Register

.

4. Comment . Commenter ACC said 12
months is not sufficient to do the work required to come into compliance with
this clarification. ACC noted that regulated industry is doing a good deal of ongoing work to come into compliance with the European Union REACH program. EPA should lengthen time to come into compliance to 18–24
months.

Response . The Agency believes that
the number of new chemical notice submissions which will be prepared to
conform to the clarification will not be large, nor will they be unusually
difficult to write. EPA’s estimate of the total number of premanufacture notices it will receive in response to this clarification is 30. After considering this comment, however, EPA agrees that 1 year could provide insufficient time to complete the new chemical notice review process for all activated phosphors affected by this clarification. Therefore, EPA has extended by 6
months the time that manufacturers and


### 8271 Federal Register / Vol. 75, No. 36 / Wednesday, February 24, 2010 / Rules and Regulations

importers who are currently manufacturing or importing affected activated phosphors would have had under the proposed clarification to complete the TSCA section 5 review

process.

Under the proposed clarification,
such manufacturers would have had to submit a premanufacture notice to EPA within 6 months after publication of the
final clarification in order for EPA to have had the entire 180 day period authorized by TSCA section 5 (90 days plus opportunity for up to a 90–day extension under TSCA section 5(c)) to complete the PMN review. This time frame may have been too short in some
circumstances. Under this final clarification, such manufacturers and importers will have up to12 months to
submit a PMN in order for EPA to have the entire 180–day review period (90 days plus opportunity for up to a 90– day extension under TSCA section 5(c)) to complete the review of a PMN. This approach will allow such manufacturers and importers additional time to compile the information necessary to prepare and submit PMNs or exemption requests. However, EPA encourages manufacturers and importers to submit PMNs or, alternatively, exemption requests as soon as possible after publication of the final clarification. Doing so will provide EPA with more time to complete any consent orders and, if necessary, establish testing requirements for those activated phosphors for which EPA may have concerns of potential unreasonable risk
to human health or the environment.

5. Comment . Commenter CPMA said this action is onerous and punitive for CPMA members, and results from EPA’s mistake. It will be disruptive if it results in materials being unavailable for manufacture during the PMN review process, and will be costly to small
businesses.

Response . As noted in Unit III.D.1., it is the statute that imposes the requirement for new chemical notice reporting. This document is not punitive; rather it clarifies EPA’s views with respect to the chemical identity of activated phosphors. The commenter is
correct that the need for this action arises from the Agency’s error, and EPA will make a diligent effort to complete
the new chemical notice reviews as quickly as possible. We recommend that manufacturers submit as promptly as possible, and well before the effective
date of the clarification. As noted in Unit III.D.4., we have lengthened the time period for coming into conformity
with the clarification to 18 months from 12 months as proposed, and the
effective date of the clarification has been chosen to enable the reviews to be completed before the effective date. CPMA provided no information to support the claim that there are such
small businesses and that the economic impact on them would be significant.
EPA estimates that the number of new chemical notices which may be received
from small businesses is 10. When EPA receives applications from small
business as a result of this clarification we will make every effort to assist these submitters to navigate the process as

necessary.

6. Comment . Commenter CPMA said the Agency has not provided any evidence in the proposed clarification that the phosphor materials subject to the clarification pose a significant risk
to humans or the environment.

Response . TSCA compels TSCA
section 5 review for new chemical substances, regardless of what information may be available regarding
their risks. A TSCA section 5 notice presents information available to the submitter regarding risk for review and assessment by EPA.

7. Comment. Commenter CPMA states that EPA rarely meets the statutory 90– day review period for inorganic substances, and that a multi-year review would impose a burden on
manufacturers of these materials.
Commenter cited several cases.

Response . EPA will strive to complete
the review of new chemical notices submitted in response to this clarification promptly. For more than 80% of submitted chemical substances, the new chemical notice review process is completed at the EPA Focus meeting, which takes place well before the end of the statutory 90–day PMN review period, and without the chemical substance being restricted or regulated in any way. For those new chemical
substances for which EPA determines that regulatory action may be necessary, the new chemical notice review period may be suspended by the submitter to enable the Agency to consider
additional information in its review and, if necessary, to develop and negotiate a consent order. The cases cited by the submitter were cases in which TSCA section 5(e) consent orders, which enabled the submitters to commence manufacture subject to certain conditions, were signed within a year of submission. The Agency
recommends that affected
manufacturers should submit their new chemical notices early in the period following publication of this document, and that they consult prior to
submission with EPA’s New Chemicals Management Branch ((202) 564–9373) in the New Chemicals Program to determine what information will facilitate quick review.

8. Comment . Commenter CPMA said
EPA has not substantiated that activated phosphors are not statutory mixtures
and this action relative to activated phosphors is inconsistent with EPA policy on other mixtures.

Response . EPA believes that activated phosphors are chemical substances, not mixtures, under TSCA. These chemical substances consist of reaction products resulting from chemical bond formation
between the activators and the host materials or precursors. As a result, the Agency considers the activators to be chemically incorporated in the activated phosphors, becoming part of the phosphor structure and composition.

9. Comment . Commenter OSRAM Sylvania said the host portion, not the activators, should be used in determining the TSCA Inventory status of phosphors.

Response . EPA believes that an activated phosphor is appropriately
viewed as a chemical substance instead
of a mixture under TSCA because the activator species (also known as dopants) are chemically incorporated
into the structure of activated phosphors, and because the dopants provide the essential property of
luminescence to the materials. Chemical incorporation is consistent with the wording used by the commenter to describe activated phosphors, such as

‘‘ The activator(s) occupies lattice points at random or interstitial positions in the

structure, ’’ and ‘‘ ...to form the host
materials with the activators incorporated into the crystal structure, ’’
and is consistent with EPA’s understanding of the nature of the
activators’ chemical interaction and incorporation during the manufacture of activated phosphors.

IV. Statutory and Executive Order

Reviews

This document announces a clarification of one aspect of the TSCA Inventory chemical identification policy. This action is not a regulatory action under Executive Order 12866,
entitled Regulatory Planning and

Review (58 FR 51735, October 4, 1993). As such, this action does not require review by the Office of Management and Budget (OMB) under Executive Order

12866.

This document does not contain any
new information collection requirements that would require additional review and approval by OMB under the Paperwork Reduction Act (PRA) 44 U.S.C. 3501 et seq . Under PRA, an agency may not conduct or sponsor, and a person is not required to


### 8272 Federal Register / Vol. 75, No. 36 / Wednesday, February 24, 2010 / Rules and Regulations

respond to a collection of information unless it displays a currently valid OMB control number, or is otherwise required to submit the specific information by a
statute. The OMB control numbers for EPA’s regulations are codified in 40 CFR chapter I, after appearing in the preamble of the final rule, are further displayed either by publication in the Federal Register or by other appropriate means, such as on the related collection instrument or form, if applicable. The display of OMB control numbers in certain EPA regulations is consolidated
in a list at 40 CFR 9.1.

The information collection activities
related to the submission of information pursuant to TSCA section 5 have already been approved by OMB under OMB Control No. 2070–0012 (EPA Information Collection Request [ICR] No. 574). The burden for that ICR is estimated to average 100 hours per respondent, including time for reading the regulations, processing, compiling, and reviewing the requested data, generating the request, storing, filing, and maintaining the data.

This action is not subject to noticeand-comment requirements under the APA or any other statute, and is not subject to the provisions of the Regulatory Flexibility Act (RFA) (5

U.S.C. 601 et seq .), or to sections 202
and 205 of the Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law 104–4). In addition, this action does not significantly or uniquely affect small governments or impose a significant intergovernmental mandate,
as described in sections 203 and 204 of
UMRA. This action will not have substantial direct effects on the 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). Nor does this action significantly or uniquely affect the communities of tribal governments as specified by Executive Order 13175, entitled
Consultation and Coordination with
Indian Tribal Governments (59 FR 22951, November 9, 2000).

Executive Orders 13045, entitled Protection of Children from Environmental Health Risks and Safety
Risks (62 FR 19885, April 23, 1997) and 13211, entitled Actions Concerning Regulations that Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001), do not apply
to this action because this action is not

‘‘ economically significant’’ as defined by section 3(f) of Executive Order 12866.
Nor does this action establish an environmental standard that may have a negatively disproportionate effect on children, or otherwise have any significant adverse effect on the supply, distribution, or use of energy.

This action does not involve any technical standards that require the Agency’s consideration of voluntary consensus standards pursuant to 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).

This action will not have an adverse impact on the environmental and health conditions in low-income and minority communities. Therefore, under Executive Order 12898, entitled Federal
Actions to Address Environmental Justice in Minority Populations and Low-Income Populations (59 FR 7629, February 16, 1994), the Agency is not required to and has not considered environmental justice-related issues.

V. Congressional Review Act

The Congressional Review Act, 5

U.S.C. 801 et seq ., as added by the Small Business Regulatory Enforcement Fairness Act of 1966, does not apply
because this action is not a rule for purposes of 5 U.S.C. 804(3).

**SUPPLEMENTARY INFORMATION :** 
A. Background

On May 22, 2009, The Weapon Systems Acquisition Reform Act (Pub. L. 111–23) was enacted to improve the organization and procedures of DoD for the acquisition of major weapon systems. This law establishes new oversight entities within DoD, as well as new and varied weapon system acquisition and management reporting requirements.

Section 202 directs the Secretary of Defense (SECDEF) to ensure that the acquisition strategy for each MDAP includes: (1) Measures to ensure competition at both the prime contract
and subcontract level of the MDAP throughout its life cycle as a means to improve contractor performance; and (2) adequate documentation of the
rationale for selection of the
