I. General Information

A. What is the purpose of this action?

In 2005, the EPA offered AFOs an opportunity to participate in a voluntary consent agreement (70 FR 4958, January 31, 2005) referred to as the Air Compliance Agreement. Under the Air Compliance Agreement, participating AFOs were responsible for, among other things, the funding for NAEMS—a 2-year, nationwide industry-run emissions monitoring study of the broiler, egg-layer, swine, and dairy industries. Monitoring under NAEMS began in the summer of 2007 and it occurred at 25 monitoring sites located in 10 states. The study collected process and emissions data for ammonia, hydrogen sulfide, particle pollution, and VOC from a representative sample of animal Start Printed Page 52057housing structures and manure storage and treatment units across the country.

The EPA plans to use these data to develop EEMs for AFOs, which will help AFOs determine and comply with any applicable regulatory responsibilities under the Clean Air Act. Additional information regarding NAEMS can be found at: https://www.epa.gov/​afos-air/​national-air-emissions-monitoring-study.

In the January 2005 Federal Register document, the EPA committed to using data generated from NAEMS and all other available, relevant data to develop EEMs. On January 19, 2011, the EPA published a call for information to obtain emissions and process data for animal confinement and manure storage and treatment processes at beef, broiler, dairy, egg-layer, swine, and turkey AFOs (76 FR 3060). Using the NAEMS data and the data obtained through the 2011 call for information, the EPA developed draft EEMs for broiler confinement operations and for open lagoons and basins at swine and dairy operations. In 2013, the EPA requested that the Science Advisory Board (SAB) conduct a review of these draft EEMs and provide feedback regarding the development of the methodologies. As noted by the SAB in their March 19, 2013, review summary, and reaffirmed by recent EPA data reviews, peer-reviewed data regarding VOC emissions from AFOs are limited.[1] Through the Call for Information in this document, the EPA is requesting that interested parties submit VOC emissions and process data available since 2011 that are relevant to the EPA's effort to develop EEMs for animal confinement and manure storage and treatment processes at broiler, dairy, egg-layer, and swine AFOs, particularly for open sources at dairy and swine operations (e.g., lagoons and basins).

B. What specific information is the EPA seeking?

The EPA is requesting data for VOC emissions from animal confinement and manure storage and treatment processes at broiler, egg-layer, swine, and dairy AFOs and related process information. Consistent with the Air Compliance Agreement, the EPA is focusing in the near term on developing EEMs for AFOs using statistical models. However, we acknowledge the recommendation that the EPA develop a process-based modeling approach that incorporates “mass balance” constraints to determine emissions from AFOs, made by the National Academy of Sciences in its December 2002 final report titled Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs. In their 2013 review, the SAB also recommended that the EPA develop process-based models for estimating emissions from AFOs. As noted in the EPA's 2013 response to the SAB review, we will carefully consider its recommendations and we will review all of the information available to us in developing the AFO EEMs. To ensure compatibility with the NAEMS data, the emissions and related process data provided to the EPA should be accompanied, if possible, by documentation that contains detailed descriptions of the following parameters, as applicable.

1. 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.

2. 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 monitoring.
  • 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., parts per million by volume) into mass emissions (e.g., pounds per hour).

3. 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).
  • Dates of production and manure management 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.
  • Data on air temperature and relative humidity within the structure for each day that the study was conducted.
  • Organics content of process inputs and outputs (e.g., feed, water, bedding, eggs, milk).
  • Organics content of manure excreted.
  • Description of any control device or work practice used in the monitored structure to reduce emissions.

4. 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).
  • 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, organic content, total Kjeldahl nitrogen, and ammoniacal nitrogen content and pH of manure entering storage and treatment process over the monitoring period.

With regard to the format of the information, we request that emissions, process, and production data be submitted to the EPA in Microsoft® Excel® spreadsheet or Access® database format. In cases where the emissions, process, and production data correspond to time increments shorter than 1 hour, please provide sufficient information and supporting documentation with the data to allow the 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.
