I. General Information

A. What is the purpose of this action?

    In 2005, EPA offered AFOs an opportunity to participate in a 
voluntary consent agreement (70 FR 4958) referred to as the Air 
Compliance Agreement. Under the Air Compliance Agreement, participating 
AFOs provided, among other things, the funding for the NAEMS, a two-
year, nationwide industry-run emissions monitoring study of the 
broiler, egg-layer, swine, and dairy industries. The NAEMS began in the 
summer of 2007 and consisted of 25 monitoring sites located in 10 
states. The study collected process and emissions data for 
PM10, PM2.5, TSP, H2S, NH3, 
and VOC from a representative sample of animal housing structures and 
manure storage and treatment units across the country. EPA plans to use 
these data to develop EEMs for AFOs, which will help AFOs determine and 
comply with their regulatory responsibilities under the CAA, CERCLA, 
and EPCRA. Additional information regarding the NAEMS can be found at: 
http://www.epa.gov/agriculture/airmonitoringstudy.html.
    EPA committed in the January 2005 Federal Register notice that it 
will use data generated from the NAEMS and all other available, 
relevant data to develop EEMs. Through this Call for Information, EPA 
is requesting that interested parties submit data that are relevant to 
EPA's effort to develop EEMs.

B. What specific information is EPA seeking?

    EPA is requesting emissions and process data for broiler, egg-
layer, swine, dairy, beef, and turkey AFOs. While EPA is interested in 
all air pollutants emissions data from AFOs, we are specifically 
seeking PM10, PM2.5, TSP, H2S, 
NH3, and VOC emissions data and related process information 
for animal confinement and manure storage and treatment processes.
    Consistent with the Air Compliance Agreement, EPA is focusing in 
the near term on developing EEMs for AFOs. However, we acknowledge the 
recommendation made by the National Academy of Sciences in its December 
2002 final report (``Air Emissions from Animal Feeding Operations: 
Current Knowledge, Future Needs'') that EPA develop a process-based 
modeling approach that incorporates ``mass balance'' constraints to 
determine emissions from AFOs. Unfortunately, manure land application 
sites, which are a necessary component for developing a process-based 
approach, were not part of the NAEMS. Although our current focus is on 
developing the EEMs, we envision developing a process-based modeling 
approach at a later date. Thus, EPA is also requesting process and 
emissions data for land application of manure.
    We will review all of the information available to us. To ensure 
compatibility with the NAEMS data, the emissions and related process 
data provided to EPA should be accompanied, to the extent possible, by 
documentation that contains detailed descriptions of the following 
parameters, as applicable.

General information:

     Description of AFO process measured (e.g., animal 
confinement structure; manure storage and treatment unit; land 
application site).
     Location of AFO process measured (e.g., physical address, 
latitude/longitude coordinates of facility).
     Beginning and ending dates of the monitoring period.

Monitoring data:

     Quality assurance and quality control plan.
     Site monitoring plan.
     Test methods, instrumentation, and standard operating 
procedures used to collect emissions and process data measurements.
     Results of audits conducted on instruments and procedures.
     Field notes and associated documentation collected during 
the study.
     Emissions data (unanalyzed or analyzed) and associated 
process data.
     Meteorological data, including average ambient 
temperature, relative humidity, pressure, wind speed, wind direction, 
and insolation (solar radiation), for each day that the study was 
conducted.
     Production data (e.g., number of eggs produced per day or 
quantity of milk produced per day).
     Calculations and assumptions used to convert concentration 
data (e.g., ppmv) into mass emissions (e.g., lb/hr).

Animal confinement structures:

     Dimensions of structures monitored.
     Designed and permitted animal capacity.
     Type, age, number, and weight of animals contained in the 
confinement structure over the duration of the monitoring period.
     Manure management system (e.g., pull-plug pit, scrape).
     Manure removal activities over the duration of the 
monitoring period.
     Ventilation method (i.e., natural or mechanical).
     Calculations and assumptions used to estimate the 
ventilation rate of the monitored confinement structure.
     Calibration procedures for instruments (e.g., flow meters, 
fan relays) used to collect data for calculating ventilation rate of 
the monitored confinement structure.
     Nitrogen content of process inputs and outputs (e.g., 
feed, water, bedding, eggs, milk).
     Nitrogen content of manure excreted.
     Description of any control device or work practice used in 
the monitored structure to reduce emissions.
    Manure storage and treatment processes:
     Type, age, number, and weight of animals contributing 
manure to the storage and treatment process over the monitoring period.
     Dimensions of storage/treatment unit monitored (e.g., 
storage pile, tank, lagoon).

[[Page 3062]]

     Depth of settled solids in storage/treatment unit.
     Temperature, pH, and reduction/oxidation potential of 
manure contained in the storage/treatment unit.
     Moisture, total solids, volatile solids, total Kjeldahl 
nitrogen, and ammoniacal nitrogen content and pH of manure entering 
storage and treatment process over the monitoring period.
    Manure land application sites:
     Type, age, number, and weight of animals contributing 
manure to the land application site.
     Method used to apply manure (e.g., direct injection, 
broadcast spreading and frequency of application.
     Area (e.g., acres, square feet) used for manure 
application over the monitoring period.
     Quantity and moisture content of manure applied.
    With regard to the format of the information, we request that 
emissions, process, and production data be submitted to EPA in 
Microsoft[supreg] Excel[supreg] spreadsheet or Access[supreg] database 
format. In cases where the emissions, process, and production data 
correspond to time increments shorter than one hour, please provide 
sufficient information and supporting documentation with the data to 
allow EPA to develop emission estimates on a per-hour and per-day 
basis. For all formats, please clearly label the units of measure of 
emissions, process, and production data submitted.
