**SUPPLEMENTARY INFORMATION :**  In January 2005, the EPA announced the voluntary Air Compliance Agreement (Agreement) with the animal feeding operations (AFO) industry. Under the Agreement, participating AFOs were responsible for funding the National Air Emissions Monitoring Study (NAEMS)—a 2-year study of animal confinement structures and manure storage and treatment units in the broiler chicken, egg-layer, swine and dairy industries. The study’s purpose was to gather emissions data that the EPA could use to develop emissions estimating methodologies (EEMs). To provide a framework for the NAEMS, AFO industry experts, university and government scientists,
and other stakeholders collaborated to develop a comprehensive monitoring plan. The study was designed to generate scientifically credible data to
characterize emissions from the participating animal sectors. The


### 14717 Federal Register / Vol. 77, No. 49 / Tuesday, March 13, 2012 / Proposed Rules

NAEMS began in the summer of 2007 and consisted of 24 monitoring sites located in nine states. In addition, Tyson Foods, Inc. collected data from two broiler sites, which are also
included in the NAEMS dataset.
Academic researchers from various
universities conducted the NAEMS study with EPA oversight. At the animal confinement sites, the study was designed to collect process and emissions data for ammonia (NH 3 ), hydrogen sulfide (H2 S), total suspended particulate matter (TSP), particulate matter with aerodynamic diameters less than 10 micrometers (PM 10), PM with aerodynamic diameters less than 2.5 micrometers (PM2.5 ), and volatile organic compounds (VOCs). For lagoons and basins, the study was designed to
collect NH 3 , H 2 S and VOCs.

In accordance with the Agreement’s monitoring protocol, the EPA developed draft EEMs for animal housing structures and manure storage and treatment units using the emissions and process data collected under the
NAEMS and other relevant information. Once the draft EEMs are final, the EPA expects that the AFO industry will use the EEMs to estimate daily and annual emissions for use in determining AFOs’ regulatory responsibilities under the Clean Air Act, the Comprehensive Environmental Response, Compensation and Liability Act, and the EmergencyPlanning and Community Right-toKnow Act.

The draft documents describe the sites monitored, the statistical methodology used to analyze the data,
and the EEMs.

The agency is requesting comment on the draft documents with particular emphasis on the statistical methodology used to develop the emissions estimating methodologies. Please submit comments within 90 days of the date of this notice. Electronic copies of the
documents are available at www.epa.gov/airquality/agmonitoring

.

On February 17, 2012, EPA’s Office of Air Quality Planning and Standards sent
a memorandum to the EPA Science Advisory Board Staff Office titled, ‘‘Animal Feeding Operations Air Emissions Estimating Methodologies
from the National Air Emissions Monitoring Study’’ asking the Science Advisory Board to review and provide
comments on these documents.

In response to EPA’s memorandum, the EPA’s Science Advisory Board has formed an expert panel to review and provide comments on these documents. The Science Advisory Board review process is an independent process. Information on submitting comments to the Science Advisory Board can be found at www.epa.gov/sab . Additional information about the Science Advisory Board process can be found at: http:// yosemite.epa.gov/sab/sabproduct.nsf/0/
ae6639dd6b79360e852579a4004e5529 !OpenDocument. The Science Advisory Board anticipates multiple meetings of the expert panel to cover the documents
in this notice.

The EPA will consider public comments received in response to this notice, public comments submitted to the Science Advisory Board, and the Science Advisory Board panel
recommendations as the final emissions estimating methodologies are developed.

Dated: February 29, 2012.
Janet McCabe, Acting Assistant Administrator.

**National Oil and Hazardous Substances Pollution Contingency**  **Plan; National Priorities List: Partial**
**Deletion of the Ellsworth Air Force Base Superfund Site** 

**AGENCY :**  Environmental Protection Agency.

**ACTION :**  Proposed rule; notice of intent.

**SUMMARY :**  The Environmental Protection Agency (EPA) Region 8 is issuing a Notice of Intent to Delete Operable Unit (OU) 1 the former Fire Protection Training Area (FPTA), along with two other Areas of Concern (AOC): The Gateway Lake Ash Study Area and the Pride Hangar Study Area of the Ellsworth Air Force Base (AFB) Superfund Site located in Meade and Pennington Counties, South Dakota, from the National Priorities List (NPL) and requests public comments on this proposed action. The NPL, promulgated pursuant to section 105 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and
Hazardous Substances Pollution Contingency Plan (NCP). The EPA and the State of South Dakota, through the Department of Environment and Natural Resources, have determined that all appropriate response actions at these identified parcels under CERCLA other than five year reviews have been completed. However, this deletion does not preclude future actions under Superfund.

This partial deletion pertains to the surface soil, unsaturated subsurface soil, surface water and sediments of Operable Unit (OU) 1, the Gateway Lake Ash Study Area, and the Pride Hangar Study Area. The groundwater medium associated with OU–11, Basewide Groundwater, will remain on the NPL and is not being considered for deletion as part of this action. The other OUs
associated with Ellsworth AFB were
deleted in 2006.
