Download as PDF sroberts on PROD1PC64 with NOTICES Federal Register / Vol. 73, No. 75 / Thursday, April 17, 2008 / Notices The affected entities of this ICR are major sources of polyvinyl chloride and copolymers production; brick and structural clay products manufacturing; clay ceramics manufacturing; and industrial, commercial, and institutional boilers and process heaters. Previous MACT standards for these source categories have been vacated by the U.S. Court of Appeals for the District of Columbia Circuit. Sources previously subject or would have been subject to those MACT standards would be those entities affected by this ICR. Owners and operators of affected sources must submit title V permit applications or amendments to establish case-by-case MACT terms and conditions. We anticipate that this ICR will cover any activities involving preparing, submitting, and reviewing the Parts 1 and 2 permit applications and applicability determinations, developing the title V permit terms and conditions, and the permit review and approval process. Burden Statement: The annual public reporting and recordkeeping burden for this collection of information is estimated to average 92.6 hours per response. Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements which have subsequently changed; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information. Respondents/Affected Entities: Respondents include owners/operators of major sources of hazardous air pollutants (HAPs) in the following source categories: polyvinyl chloride and copolymers production, brick and structural clay products manufacturing, clay ceramics manufacturing, and industrial, commercial, and institutional boilers and process heaters. Estimated Number of Respondents: 2,573. Frequency of Response: Once. Estimated Total Annual Hour Burden: 151,730. Estimated Total Annual Cost: $9,995,666. VerDate Aug<31>2005 17:08 Apr 16, 2008 Jkt 214001 Changes in the Estimates: There is a decrease of 20,470 hours in the total estimated burden previously identified in the expired ICR in the OMB Inventory of Approved ICR Burdens. The ICR 1648.04 spanned the period in which the section 112(j) rule would have applied to any of the 59 source categories covered by the 2000 MACT standards (the 10-year bin). This ICR would affect only the 4 source categories covered by the MACT standards that have been vacated by the United States Court of Appeals for the District of Columbia Circuit. Unlike ICR No. 1648.04, which estimated the burden from the Part 1 application only (because all the MACT standards were promulgated before Part 2 applied), this ICR estimates burden for preparing, submitting, and reviewing the Parts 1 and 2 permit applications and applicability determinations, developing the title V permit terms and conditions, and the permit review and approval process. This ICR also estimates the number of responses on a facility basis instead of an individual boiler basis as the previous ICR did, because each facility will submit one application for the facility, not each boiler. Finally, EPA has updated the labor rates for respondents, State, Local, and Tribal agencies, and the EPA. These adjustments were made to more accurately reflect the true cost of an hour of labor for the respondents, State, Local, and Tribal agencies, and the EPA. The unloaded hourly rates are different because they are based on the latest available rates from the BLS and the OPM. In summary, the difference in the burden estimate is due to the adjustments discussed above, including number of respondents, submittal of permit applications, development of the permit, and updated labor rates.

Does this Action Apply to Me? A. What are SPP and ChAMP? SPP unites the efforts of Canada, Mexico, and the United States in an initiative that is committed to accelerating and strengthening the national and regional risk-based assessment and management of chemicals. This effort is pursuant to a commitment made by President Bush, Canadian Prime Minister Stephen Harper, and Mexican President Felipe Calderon in Montebello, Quebec, in August 2007. SPP builds on current work underway in the United States and Canada and will complement North American efforts under the Commission on Environmental Cooperation’s Sound Management of Chemicals project. The SPP initiative includes a number of regional and national commitments. The partners will share scientific information, technical understanding, best practices, and risk management approaches, and will better coordinate research on new approaches to chemical testing and assessment. When EPA announced the SPP commitment, it stated its intention to obtain stakeholder input and the public meeting meets that goal in part. ChAMP is the name given by EPA to its efforts to meet the SPP commitment to complete initial assessments and take action, if necessary, on thousands of chemicals produced above 25,000 lbs/year. This commitment includes both HPV and MPV chemicals, builds on the U.S. HPV Challenge Program and Canada’s work on chemical categorization and may also include two new initiatives discussed below. You may be potentially affected by this action if you manufacture, import, process, or use chemical substances subject to TSCA. Potentially affected entities may include, but are not limited to chemical manufacturers, e.g., persons manufacturing, importing, processing, or using chemicals for commercial purposes. Since other entities may also be interested, the Agency has not attempted to describe all the specific entities that may have an interest in this matter. If you have any questions regarding the applicability of this action to a particular entity, consult the technical person listed under FOR FURTHER INFORMATION CONTACT. sroberts on PROD1PC64 with NOTICES B.

VerDate Aug<31>2005 17:08 Apr 16, 2008 Jkt 214001 B. What Action is the Agency Taking? In accordance with U.S. SPP commitments, by 2012, EPA under ChAMP will assess and initiate action, if necessary, on the over 6,750 existing chemicals produced above 25,000 lbs/ year in this country. These efforts will position the United States to take action to ensure that these chemicals are produced and used in ways that do not present unacceptable risks to health and the environment. The approximately 6,750 chemicals encompassed by the SPP commitment and ChAMP include 2,750 organic HPV chemicals produced at or above 1 million lbs/year. In assessing these chemicals, the Agency will prepare screening-level characterizations of hazard, exposure, and risk, and will use those characterizations to develop an initial risk-based prioritization (RBP). HPV Challenge submissions will generally provide the base hazard data used in the hazard characterizations, while the 2006 PO 00000 Frm 00018 Fmt 4703 Sfmt 4703 Inventory Update Reporting (IUR) will provide the bulk of the use and exposure information used in the exposure characterizations. These screening-level hazard and exposure characterizations will be combined to develop screening-level risk characterizations, which summarize EPA’s current thinking regarding the potential risks of HPV chemicals or categories. Together, these characterization documents will support an initial RBP identifying the relative priorities of these chemicals and informing risk management options. More detail on the RBP process, including characterization and prioritization documents, can be found at http://www.epa.gov/CHAMP by following the RBP links. In addition to the 2,750 organic HPV chemicals, the United States committed under SPP to assess and initiate action, if necessary, on an additional 4,000 organic MPV chemicals. MPV chemicals are produced at or greater than 25,000 lbs/year but at less than 1 million lbs/ year. The Agency generally does not have the same degree of hazard and exposure data on these chemicals, therefore, the assessment scheme will differ from that applied to the HPV chemicals. For MPV chemicals, EPA intends to develop health and environmental hazard and environmental fate characterizations using available data, Canadian categorization results, EPA Structure Activity Relationship (SAR) analysis input, and knowledge gained under the HPV Challenge Program, including on categories of chemicals. The hazard and fate characterizations will be used to support development of hazard based prioritizations to identify MPV chemicals that may need follow-up (e.g., hazard/fate testing, exposure information, risk management, etc.). As with HPV chemicals, the Agency envisions employing both voluntary and regulatory actions for MPV chemicals. As mentioned in this unit, ChAMP may include two new initiatives identified by EPA. The first of these concerns approximately 750 inorganic HPV chemicals, which were first reported under the 2006 IUR cycle. Recognizing the value of the original HPV Challenge Program published in the Federal Register issue of December 26, 2000 (65 FR 81686) (FRL–6754–6) in making available to EPA and the public basic screening level data on many organic HPV chemicals, EPA believes there is value in extending the approach to inorganic HPV chemicals. Several domestic and international activities provide a starting point for development of an Inorganics High Production E:\FR\FM\17APN1.SGM 17APN1 Federal Register / Vol. 73, No. 75 / Thursday, April 17, 2008 / Notices sroberts on PROD1PC64 with NOTICES Volume (IHPV) Challenge Program in the near future. The Agency is considering applying the general approach used in the HPV Challenge Program (sponsorship commitments, development of test plans, public review step, completion of data package, and submission to EPA) as well as the inorganics guidance developed by the Organization for Economic Cooperation and Development (OECD) for use in its HPV Program. Additional information on OECD’s guidance on inorganics can be found at: http://www.oecd.org/ document/7/0,3343, en_2649_34379_1947463 _1_1_1_1,00.html. It is anticipated that an IHPV Challenge Program, if started in 2008, could be completed by approximately 2011–2012. The 2011 IUR reporting cycle will include exposure/use data for inorganic HPV chemicals which would allow for EPA to consider both hazard and exposure elements and develop RBPs for these chemicals. An assessment approach similar to that for organic MPV chemicals could be applied to inorganic medium production volume (IMPV) chemicals at a later date. The second new initiative concerns an effort to potentially ‘‘reset’’ the TSCA Inventory. The original TSCA Inventory was compiled in 1979 consisting of 62,000 chemicals. Since then approximately 21,000 new chemicals have been added to the TSCA Inventory. Under TSCA section 8(b), EPA is required to ‘‘compile, keep current, and publish a list of each chemical substance which is manufactured or processed in the United States.’’ Pursuant to this authority, and in an effort to better understand the universe of chemicals actually in commerce at present, EPA is considering an effort to reset the TSCA Inventory. While there are a number of issues and questions that would need to be resolved if EPA does move forward with this effort it necessarily will need to obtain information on currently manufactured and/or imported chemicals. Additional information on ChAMP and EPA’s current thinking can be found at: http:// www.epa.gov/CHAMP. C. Why is EPA Taking This Action? EPA believes that ChAMP provides a sound basis for realizing further progress by EPA on assessing and managing chemicals. The SPP effort has great potential to achieve greater public health and environmental protection by promoting a more integrated approach to chemicals assessment and management in North America. By sharing information and the assessment VerDate Aug<31>2005 17:08 Apr 16, 2008 Jkt 214001 burden North America will be able to more quickly, efficiently, and costeffectively determine the need for, and possibly take, risk management actions on a greater number of chemicals. Work done by the U.S. to meet its 2012 SPP commitment represents an important contribution to this effort and to meeting U.S. domestic chemical assessment and management needs. The two new initiatives being considered complement and strengthen ChAMP by expanding EPA’s efforts to include inorganic HPV chemicals and an effort focused on resetting the TSCA Inventory. 20923 Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) to improve public health protection through the control of microbial contaminants by focusing on systems with elevated Cryptosporidium risk. EPA has determined that the proposed Stage 2 DDBPR and LT2ESWTR revisions submitted by Arkansas are no less stringent than the corresponding federal regulations. Therefore, EPA proposes to approve these program revisions. ENVIRONMENTAL PROTECTION AGENCY All interested parties may request a public hearing.

II. Background

A. What are SPP and ChAMP?

    SPP unites the efforts of Canada, Mexico, and the United States in 
an initiative that is committed to accelerating and strengthening the 
national and regional risk-based assessment and management of 
chemicals. This effort is pursuant to a commitment made by President 
Bush, Canadian Prime Minister Stephen Harper, and Mexican President 
Felipe Calderon in Montebello, Quebec, in August 2007. SPP builds on 
current work underway in the United States and Canada and will 
complement North American efforts under the Commission on Environmental 
Cooperation's Sound Management of Chemicals project.
    The SPP initiative includes a number of regional and national 
commitments. The partners will share scientific information, technical 
understanding, best practices, and risk management approaches, and will 
better coordinate research on new approaches to chemical testing and 
assessment. When EPA announced the SPP commitment, it stated its 
intention to obtain stakeholder input and the public meeting meets that 
goal in part. ChAMP is the name given by EPA to its efforts to meet the 
SPP commitment to complete initial assessments and take action, if 
necessary, on thousands of chemicals produced above 25,000 lbs/year. 
This commitment includes both HPV and MPV chemicals, builds on the U.S. 
HPV Challenge Program and Canada's work on chemical categorization and 
may also include two new initiatives discussed below.

B. What Action is the Agency Taking?

    In accordance with U.S. SPP commitments, by 2012, EPA under ChAMP 
will assess and initiate action, if necessary, on the over 6,750 
existing chemicals produced above 25,000 lbs/year in this country. 
These efforts will position the United States to take action to ensure 
that these chemicals are produced and used in ways that do not present 
unacceptable risks to health and the environment. The approximately 
6,750 chemicals encompassed by the SPP commitment and ChAMP include 
2,750 organic HPV chemicals produced at or above 1 million lbs/year. In 
assessing these chemicals, the Agency will prepare screening-level 
characterizations of hazard, exposure, and risk, and will use those 
characterizations to develop an initial risk-based prioritization 
(RBP). HPV Challenge submissions will generally provide the base hazard 
data used in the hazard characterizations, while the 2006 Inventory 
Update Reporting (IUR) will provide the bulk of the use and exposure 
information used in the exposure characterizations. These screening-
level hazard and exposure characterizations will be combined to develop 
screening-level risk characterizations, which summarize EPA's current 
thinking regarding the potential risks of HPV chemicals or categories. 
Together, these characterization documents will support an initial RBP 
identifying the relative priorities of these chemicals and informing 
risk management options. More detail on the RBP process, including 
characterization and prioritization documents, can be found at http://
www.epa.gov/CHAMP by following the RBP links.
    In addition to the 2,750 organic HPV chemicals, the United States 
committed under SPP to assess and initiate action, if necessary, on an 
additional 4,000 organic MPV chemicals. MPV chemicals are produced at 
or greater than 25,000 lbs/year but at less than 1 million lbs/year. 
The Agency generally does not have the same degree of hazard and 
exposure data on these chemicals, therefore, the assessment scheme will 
differ from that applied to the HPV chemicals. For MPV chemicals, EPA 
intends to develop health and environmental hazard and environmental 
fate characterizations using available data, Canadian categorization 
results, EPA Structure Activity Relationship (SAR) analysis input, and 
knowledge gained under the HPV Challenge Program, including on 
categories of chemicals. The hazard and fate characterizations will be 
used to support development of hazard based prioritizations to identify 
MPV chemicals that may need follow-up (e.g., hazard/fate testing, 
exposure information, risk management, etc.). As with HPV chemicals, 
the Agency envisions employing both voluntary and regulatory actions 
for MPV chemicals.
    As mentioned in this unit, ChAMP may include two new initiatives 
identified by EPA. The first of these concerns approximately 750 
inorganic HPV chemicals, which were first reported under the 2006 IUR 
cycle. Recognizing the value of the original HPV Challenge Program 
published in the Federal Register issue of December 26, 2000 (65 FR 
81686) (FRL-6754-6) in making available to EPA and the public basic 
screening level data on many organic HPV chemicals, EPA believes there 
is value in extending the approach to inorganic HPV chemicals. Several 
domestic and international activities provide a starting point for 
development of an Inorganics High Production

[[Page 20923]]

Volume (IHPV) Challenge Program in the near future. The Agency is 
considering applying the general approach used in the HPV Challenge 
Program (sponsorship commitments, development of test plans, public 
review step, completion of data package, and submission to EPA) as well 
as the inorganics guidance developed by the Organization for Economic 
Cooperation and Development (OECD) for use in its HPV Program. 
Additional information on OECD's guidance on inorganics can be found 
at: http://www.oecd.org/document/7/0,3343,en_2649_34379_1947463_1_
1_1_1,00.html.
    It is anticipated that an IHPV Challenge Program, if started in 
2008, could be completed by approximately 2011-2012. The 2011 IUR 
reporting cycle will include exposure/use data for inorganic HPV 
chemicals which would allow for EPA to consider both hazard and 
exposure elements and develop RBPs for these chemicals. An assessment 
approach similar to that for organic MPV chemicals could be applied to 
inorganic medium production volume (IMPV) chemicals at a later date.
    The second new initiative concerns an effort to potentially 
``reset'' the TSCA Inventory. The original TSCA Inventory was compiled 
in 1979 consisting of 62,000 chemicals. Since then approximately 21,000 
new chemicals have been added to the TSCA Inventory. Under TSCA section 
8(b), EPA is required to ``compile, keep current, and publish a list of 
each chemical substance which is manufactured or processed in the 
United States.'' Pursuant to this authority, and in an effort to better 
understand the universe of chemicals actually in commerce at present, 
EPA is considering an effort to reset the TSCA Inventory. While there 
are a number of issues and questions that would need to be resolved if 
EPA does move forward with this effort it necessarily will need to 
obtain information on currently manufactured and/or imported chemicals. 
Additional information on ChAMP and EPA's current thinking can be found 
at: http://www.epa.gov/CHAMP.

C. Why is EPA Taking This Action?

    EPA believes that ChAMP provides a sound basis for realizing 
further progress by EPA on assessing and managing chemicals. The SPP 
effort has great potential to achieve greater public health and 
environmental protection by promoting a more integrated approach to 
chemicals assessment and management in North America. By sharing 
information and the assessment burden North America will be able to 
more quickly, efficiently, and cost-effectively determine the need for, 
and possibly take, risk management actions on a greater number of 
chemicals. Work done by the U.S. to meet its 2012 SPP commitment 
represents an important contribution to this effort and to meeting U.S. 
domestic chemical assessment and management needs. The two new 
initiatives being considered complement and strengthen ChAMP by 
expanding EPA's efforts to include inorganic HPV chemicals and an 
effort focused on resetting the TSCA Inventory.
