**Workshop To Review Initial Draft Materials for the Nitrogen Oxides**  **(NO** X**) Integrated Science Assessment (ISA) for Health Effects** 

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

**ACTION :**  Notice of Workshop.

**SUMMARY :**  As part of the review of the air quality criteria for nitrogen oxides (NO X) and primary (health-based) National Ambient Air Quality Standards (NAAQS) for nitrogen dioxide (NO 2 ), EPA is announcing a workshop to evaluate preliminary draft materials that will inform the development of the NO X Integrated Science Assessment (ISA) for health effects. The workshop is being organized by EPA’s National Center for Environmental Assessment (NCEA) within the Office of Research and Development and will be held on June 11, 2013, in Research Triangle Park, North Carolina and will be open to attendance by interested public observers on a first-come, first-served basis up to the limits of available space.

**DATES :**  The workshop will be held on June 11, 2013, beginning at 9:30 a.m. and ending at 5:00 p.m.

**ADDRESSES :**  The workshop will be held in the auditorium of EPA’s main campus, 109 T.W. Alexander Drive, Research Triangle Park, North Carolina.

**FOR FURTHER INFORMATION CONTACT :**  Questions regarding information, registration, and logistics for the workshop should be directed to Ms. Brianna Young, telephone: 919–541– 9765; facsimile: 919–541–1818; email: young.brianna@epa.gov. Questions regarding the scientific and technical aspects of the workshop should be directed to Dr. Molini Patel, telephone: 919–541–1492; facsimile: 919–541– 1818; email: patel.molini@epa.gov.

**SUPPLEMENTARY INFORMATION :**  I. Summary of Information About the Workshop

Section 109(d) of the Clean Air Act (CAA) requires the U.S. EPA to conduct periodic reviews of the air quality criteria for each air pollutant listed under section 108 of the Act. Based on such reviews, EPA is to retain or revise the NAAQS for a given pollutant as appropriate. As part of these reviews, NCEA assesses newly available scientific information and develops ISA documents (formerly known as Air Quality Criteria Documents) that provide the scientific basis for the reviews of the NAAQS.

NCEA-Research Triangle Park is holding this workshop to inform the Agency’s evaluation of the scientific evidence for the review of the primary NAAQS for NO 2 . Section 109(b)(1) of the CAA defines primary NAAQS as standards, ‘‘the attainment and maintenance of which in the judgment of the Administrator, based on such criteria and allowing an adequate margin of safety, are requisite to protect the public health.’’ EPA intends to develop a separate ISA, and NAAQSreview, for the secondary (welfarebased) NAAQS for NO 2 , in conjunction with a review of the secondary NAAQS for sulfur dioxide. The purpose of the workshop is to obtain review of the scientific content of preliminary draft materials that will inform the development of the draft health effects ISA. Workshop sessions will include review and discussion of preliminary draft materials on the atmospheric chemistry of and human exposure to NO X as well as health effects evidence from in vivo and in vitro animal toxicology, human clinical, and epidemiology studies. In addition, roundtable discussions will help identify key studies or concepts within each discipline to assist EPA in integrating relevant literature within and across disciplines. These preliminary materials are not being released as an external draft but will be used to guide workshop discussions and inform the development of the draft health effects ISA. This workshop is planned to help ensure that the ISA, once developed, is up-to-date and focuses on the key evidence to inform the scientific understanding for the review of the primary NAAQS for NO X . EPA is planning to release the first external review draft health effects ISA for NO X for review by the Clean Air Scientific Advisory Committee and the public in August 2013.
II. Workshop Information

Members of the public may attend the workshop as observers. Space is limited, and reservations will be accepted on a first-come, first-served basis.

**Standards of Performance for New Stationary Sources, National Emission**  **Standards for Hazardous Air Pollutants, and the Stratospheric**  **Ozone Protection Program: Recent Posting to the Applicability**  **Determination Index (ADI) Database System of Agency Applicability**  **Determinations, Alternative Monitoring Decisions, and Regulatory**  **Interpretations**

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

**ACTION :**  Notice of availability.

**SUMMARY :**  This notice announces applicability determinations, alternative monitoring decisions, and regulatory interpretations that EPA has made under the New Source Performance Standards (NSPS); the National Emission Standards for Hazardous Air Pollutants (NESHAP); and/or the Stratospheric Ozone Protection Program.

**FOR FURTHER INFORMATION CONTACT :**  An electronic copy of each complete document posted on the Applicability Determination Index (ADI) database system is available on the Internet through the Office of Enforcement and Compliance Assurance (OECA) Web site
at: http://www.epa.gov/compliance/ monitoring/programs/caa/adi.html . The letters and memoranda on the ADI may be located by control number, date, author, subpart, or subject search. For questions about the ADI or this notice, contact Maria Malave at EPA by phone at: (202) 564–7027, or by email at: malave.maria@epa.gov. For technical questions about individual applicability determinations or monitoring decisions, refer to the contact person identified in the individual documents, or in the absence of a contact person, refer to the author of the document.

**SUPPLEMENTARY INFORMATION :**  Background

The General Provisions of the NSPS in 40 Code of Federal Regulations (CFR) part 60 and the General Provisions of the NESHAP in 40 CFR part 61 provide that a source owner or operator may request a determination of whether certain intended actions constitute the commencement of construction, reconstruction, or modification. EPA’s written responses to these inquiries are commonly referred to as applicability determinations. See 40 CFR 60.5 and 61.06. Although the NESHAP part 63 regulations [which include Maximum Achievable Control Technology (MACT) standards] and § 111(d) of the Clean Air Act (CAA) contain no specific regulatory provision providing that sources may request applicability determinations, EPA also responds to written inquiries regarding applicability for the part 63 and § 111(d) programs. The NSPS and NESHAP also allow sources to seek permission to use monitoring or recordkeeping that is different from the promulgated requirements. See 40 CFR 60.13(i), 61.14(g), 63.8(b)(1), 63.8(f), and 63.10(f). EPA’s written responses to these inquiries are commonly referred to as alternative monitoring decisions. Furthermore, EPA responds to written inquiries about the broad range of NSPS and NESHAP regulatory requirements as they pertain to a whole source category. These inquiries may pertain, for example, to the type of sources to which the regulation applies, or to the testing, monitoring, recordkeeping, or reporting requirements contained in the regulation. EPA’s written responses to these inquiries are commonly referred to as regulatory interpretations. EPA currently compiles EPA-issued NSPS and NESHAP applicability determinations, alternative monitoring decisions, and regulatory interpretations, and posts them to the ADI on a quarterly basis. In addition, the ADI contains EPA-issued responses to requests pursuant to the stratospheric ozone regulations, contained in 40 CFR part 82. The ADI is an electronic index on the Internet with over one thousand EPA letters and memoranda pertaining to the applicability, monitoring, recordkeeping, and reporting requirements of the NSPS, NESHAP, and stratospheric ozone regulations. Users can search for letters and memoranda by date, office of issuance, subpart, citation, control number, or by string word searches.

Today’s notice comprises a summary of 63 such documents added to the ADI on March XX, 2013. This notice lists the subject and header of each letter and memorandum, as well as a brief abstract of the letter or memorandum. Complete copies of these documents may be obtained from the ADI through the OECA Web site at: www.epa.gov/ compliance/monitoring/programs/caa/ adi.html
Summary of Headers and Abstracts

The following table identifies the database control number for each document posted on the ADI database system on March XX, 2013; the applicable category; the section(s) and/ or subpart(s) of 40 CFR part 60, 61, or 63 (as applicable) addressed in the document; and the title of the document, which provides a brief description of the subject matter.

We have also included an abstract of each document identified with its control number after the table. These abstracts are provided solely to alert the public to possible items of interest and are not intended as substitutes for the full text of the documents. This notice does not change the status of any document with respect to whether it is ‘‘of nationwide scope or effect’’ for purposes of CAA § 307(b)(1) For example, this notice does not convert an applicability determination for a particular source into a nationwide rule. Neither does it purport to make a previously non-binding document binding.
