ACKNOWLEDGEMENTS AND DISCLAIMER

This document was prepared by Tetra Tech, Inc., under Contract No. EP-C-11-009, Work 

Assignment 1-17, under the direction and review of the Office of Wastewater Management.

Neither the United States government nor any of its employees, contractors, subcontractors, or 

other employees make any warranty, expressed or implied, or assume any legal liability or 

responsibility for any third party’s use of, or the results of such use of, any information, 

apparatus, product, or process discussed in this report, or represent that its use by such a third 

party would not infringe on privately owned rights.

NPDES CAFO Reporting Rule Information Search

For each state, Tetra Tech searched the web sites for the state environmental department and 

the state department of agriculture for a list of CAFOs in the state, a map of CAFOs in the state, 

or other information identifying individual CAFOs. Tetra Tech also searched web sites for state 

farm bureaus and conservation districts, and performed a general keyword search for CAFO 

information presented through industry or environmental groups. The search attempted to find 

the following information for CAFOs in each state: 

Owner/Operator Name

Owner/Operator Address

CAFO Name

CAFO Address

CAFO Location

CAFO Latitude/Longitude

NPDES Permit Status

NPDES Permit Number

Type of Confined Animals

Number of Animals

Acres of Land Available for Land Application

For each state, Tetra Tech compiled as much facility identifying information as possible, 

according to the categories listed above, based on the available resources.

In addition to an internet search, Tetra Tech screened EPA’s Integrated Compliance Information 

System (ICIS) and Permit Compliance System (PCS) databases for permitted CAFO 

information. Tetra Tech also evaluated the EPA Enforcement and Compliance History Online

(ECHO) site as a possible source of information to identify and locate CAFOs. Since ECHO 

displays all permits for a facility, it is a potential resource for locating non-permitted CAFOs (i.e., 

if a CAFO without an NPDES CAFO permit nevertheless possesses another type of permit, 

such as an air permit, that identifies its location).

The notes below summarize the information that was found for each state. In some cases, Tetra 

Tech found maps or other resources that indicate the availability of site-specific CAFO 

information even if the information itself was not accessible on-line. Those resources are 

identified below, along with contact information, where available, that may be used to request 

the data.

Notes

EPA Region 1

Connecticut

Located a report with two maps of CAFO locations in Connecticut. See section 2 of 

http://www.ct.gov/dep/lib/dep/water_regulating_and_discharges/cafo/03finalrpt.pdf. 

Facility-specific information would need to be requested from the Connecticut 

Department of Environmental Protection.

Also located a report generated for the Connecticut Department of Environmental 

Protection (DEP) that mapped dairy farms and discussed acres of land available for 

land application of dairy and poultry manure. See Figures 3-1 through 3-3 of 

http://easternrcd-ct.org/NutrientManagement/NMpdfs/CAFOFeasibilityStudy.pdf.

Facility-specific information would need to be requested from the author (WrightPierce) or the CT DEP (dep.webmaster@ct.gov).

the state Department of Agriculture website or a general Google web search for New 

Jersey CAFOs.

Puerto Rico 

Could not locate any information about CAFOs in Puerto Rico.
October 31, 2011, revised March 1, 2012 7

US Virgin Islands

Could not locate any information about CAFOs in the Virgin Islands. 

EPA Region 3

Delaware 

EPA Region 3 provides a list of the number of medium and large AFOs in each state 

of EPA Region 3. See http://www.epa.gov/reg3wapd/pdf/pdf_nps/afo/all_data.pdf.

The business and owner name, city, animal type, and number of animals for 300 

CAFOs are identified in the 2009 PDF from Delaware Department of Agriculture at 

http://dda.delaware.gov/nutrients/forms/2009/122009_Current%20CAFO%20List.pdf. 

The state would need to be contacted to obtain the specific locations 

(latitude/longitude or address) for the records displayed in the PDF. The surface 

water discharge permitting section of the Division of Water can be contacted at 302-

739-9946, or a public information request can be submitted via the following web 

site: 

http://www.dnrec.delaware.gov/wr/Information/Pages/PublicInformationRequest.aspx

Maryland

The State of Maryland issues permits for CAFOs and MAFOs (large AFOs that do 

not discharge.) Maryland Department of the Environment maintains a search engine 

for all regulated CAFOs and MAFOs. See 

http://www.mde.state.md.us/programs/Land/SolidWaste/CAFOMAFO/Pages/Progra

ms/LandPrograms/Solid_Waste/cafo_search/CAFO.aspx. The listed facilities 

included CAFOs and MAFOs, but the list did not include the permit number for the 

facilities. A map of Maryland CAFOs is found at 

http://cbfn.rhizalabs.com/cbi/snapshot/page?concept=~0176dd2a1e69e011e0b1deb

4f4e60a530f. The data set for this map has been deleted, but the web site lists the 

author of the map and provides a contact email (Brent Walls, 

brent@potomacriverkeeper.org)

Pennsylvania 

The Pennsylvania Department of Environmental Protection (DEP) maintains a 

searchable database of permitted facilities (eFACTS) at 

http://www.ahs2.dep.state.pa.us/eFACTSWeb/criteria_client.aspx. A search could 

not be completed and exported to excel however due to errors with the site.

The Pennsylvania Watershed Implementation Plan 

(http://www.portal.state.pa.us/portal/server.pt/document/1010622/chesapeake_bay_

wip_november_29%2C_2010_pdf?qid=36945254&rank=1, See page 33) indicates 

that the state maintains a master list of CAFOs and has mapped the location of these 

CAFOs. Information on filing a public records request is found at 

http://www.portal.state.pa.us/portal/server.pt/community/public_records/19207. 

Virginia

Virginia maintains spreadsheets of active permit applications for the Virginia 

Pollutant Discharge Elimination System (VPDES) and the Virginia Pollution 

Abatement (VPA) programs. See 

http://www.deq.virginia.gov/Programs/Water/PermittingCompliance/PermitApplication
October 31, 2011, revised March 1, 2012 8

Status.aspx. The VPA program regulates the land application of animal wastes. Each 

list does not contain the number of animals confined and therefore, Tetra Tech could 

not determine if each operation is a CAFO or an AFO.

West Virginia

Could not locate any information about CAFOs in West Virginia.

Animal feeding operation GIS data are available through AEGIS at 

http://www.aegis.jsu.edu/WV/WVdownload.html.

EPA Region 4

Florida

Florida Department of Environmental Protection maintains a spreadsheet of facility 

information for permitted CAFOs and AFOs. See 

http://www.dep.state.fl.us/water/wastewater/facinfo.htm.

Alabama

A list of AFOs and CAFOs that have registered with the State is provided at the 

following website: http://www.adem.state.al.us/programs/water/cafo.cnt. The facility's 

Master ID list can be used to find the address of each facility using ADEM efile at 

http://edocs.adem.alabama.gov/eFile/. The Alabama list was used to compare to the 

ICIS file of facilities to determine the accuracy of ICIS data.

Mississippi 

Mississippi DEQ maintains a searchable website for NPDES permits 

(http://opc.deq.state.ms.us/search_ai_alt.aspx#grid). Individual permits were 

identified by reviewing the list of individual permits and identifying individually 

permitted CAFOs. General permits were available for poultry and swine. CAFO 

NPDES permitting information is found at 

http://www.deq.state.ms.us/MDEQ.nsf/page/epd_AgriculturalBranchEPD?OpenDocu

ment.

The Mississippi Department of Agriculture and Commerce 

(http://www.mdac.state.ms.us/) was searched but no information was found. 

Georgia

Could not locate any information about CAFOs in Georgia.

Kentucky

Could not locate any information about CAFOs in Kentucky.

General CAFO permitting information is available at: 

http://water.ky.gov/permitting/Pages/AFOsandCAFOs.aspx

KPDES permits issued and permit applications are searchable by date and permit 

program (e.g., Wastewater) at:

Tennessee

Site-specific CAFO information was obtained from the Tennessee Department of 

Environment and Conservation at: http://environmentonline.state.tn.us:7654/pls/enf_reports/f?p=9034:34001:719316808965690::NO:::

The information obtained includes multiple permit listings (i.e., NPDES and operating 

permits) for certain CAFOs.

North Carolina

Site-specific CAFO information was obtained online from the North Carolina 

Department of Environment and Natural Resources' Division of Water Quality at:

http://portal.ncdenr.org/web/wq/aps/afo/perm

Redundant NPDES permit numbers reflect different regulated activities (e.g., Dairy 

Calf, Dairy Heifer, or Milk Cow). CAFO location data includes County and 

Latitude/Longitude.

South Carolina

No site-specific information for South Carolina CAFO operations was obtained.

GIS data layers for Permitted Agricultural Facilities (Animal Farms) are available for 

download from the South Carolina Department of Health and Environmental Control 

at: http://www.scdhec.gov/gis/GIS.aspx. "The downloadable GIS data layers provide 

spatial location of past and present agricultural facilities (animal houses and potential 

field application sites). Publication_Date: 6/18/01"

EPA Region 5

Illinois

No site-specific information for Illinois CAFOs was located.

EPA Region 5 provided information regarding Illinois CAFOs at

http://www.epa.gov/region05/illinoisworkplan/. The dates on these lists are from 2009 

and therefore may not be current. As of February 2011, EPA Region 5 and Illinois 

have agreed on a workplan for the state to implement CAFO NPDES permitting 

procedures.

Ohio

A map that displays the location of Concentrated Animal Feeding Facilities (CAFFs) 

permitted by the Ohio Department of Agriculture (ODA) and Concentrated Animal 

Feeding Operations (CAFOs) permitted by the Ohio Environmental Protection 

Agency (OEPA) can be found here: http://wwwapp.epa.ohio.gov/dsw/gis/cafo/.

Questions or comments regarding this map can be submitted to Jon Bernstein in the 

Division of Surface Water at jon.bernstein@epa.state.oh.us. 

Wisconsin

A map of Wisconsin's Wisconsin Pollutant Discharge Elimination System permitted 

CAFOs is found at http://dnr.wi.gov/runoff/pdf/ag/cafo_map.pdf and is dated June 

2010. 

A list of CAFO permittees is provided at 

http://dnr.wi.gov/runoff/agriculture/cafo/permits/cafo_all.asp. For more information 

about Wisconsin CAFOs, please contact Tom Bauman 608-266-9993 with the 

Wisconsin Department of Natural Resources. 

Minnesota

No site-specific information for Minnesota CAFOs was located. 

EPA Region 6 

Arkansas

Arkansas requires all confined animal operations, regardless of size, that use a liquid 

waste management system obtain a permit from the Department. Facilities may be 

covered under an individual or general permit. The actual permits or list of enrollees 

could not be found. Arkansas recently public noticed its general NPDES permit for 

CAFOs. It has not yet been adopted.

Facilities listed from Arkansas were retrieved from a spreadsheet of permitted 

facilities maintained by the state, found at 

http://www.adeq.state.ar.us/home/pdssql/pds.asp. The list sometimes provided the 

number of animals present at a facility, but for others where this information was not 

provided, it could not be determined whether the facilities are CAFOs or AFOs using 

a liquid waste management system. 
October 31, 2011, revised March 1, 2012 11

Louisiana

The Louisiana Department of Environmental Quality does not have a list of permits in 

an electronic format on its NPDES site. They do provide pdf lists of permit 

applications received per week from 2005 through current 2011. The website 

(http://www.deq.louisiana.gov/portal/DIVISIONS/PublicParticipationandPermitSuppor

t/PermitApplicationsReceived.aspx) states that an electronic copy of the Permit 

Applications Received List can be requested by email by contacting Chris Mayeux at

chris.mayeux@la.govor by telephone at (225) 219-3247.

New Mexico 

New Mexico does not have CAFO NPDES authorization, but does require 

groundwater permits for feeding operations that may affect groundwater. A list of 

these permits is provided at http://www.nmenv.state.nm.us/gwb/NMED-GWQBPermits.htm. Because this list does not provide animal numbers per facility, it could 

not be determined whether the facilities listed are CAFOS or AFOs.

Oklahoma

Oklahoma does not have CAFO NPDES authority. The Department of Agriculture 

maintains lists of new or expanding registered poultry feeding operations; it could not 

be determined based on the information presented (i.e., whether the manure 

handling system was wet or dry) for each listing whether it was a CAFO or AFO. See 

http://www.ok.gov/~okag/aems/rpfo.htm. 

Texas

Texas maintains a list of dischargers covered under the general permit at 

http://www5.tceq.state.tx.us/wq_dpa/index.cfm. The list contains a link to the NOI 

which contains all the info requested on the spreadsheet; however there are 728

active permittees with 595 distinct permits under the GP (as of March 1, 2012). A 

search of ICIS listed 625 facilities.

EPA Region 7

Iowa

The Iowa Department of Natural Resources maintains a spreadsheet of currently 

permitted facilities on its website. See 

http://www.iowadnr.gov/InsideDNR/RegulatoryWater/NPDESWastewaterPermitting/

CurrentNPDESPermits.aspx.

The Iowa State Association of Counties maintains 3 maps of animal feeding 

operations in Iowa. See http://www.iowacounties.org/News/CAFosinIowa.htm. The 

webpage indicates that the maps show CAFOs but the maps state they show AFOs, 

so it is not clear which is the correct label. 

IA DNR also maintains a database of facilities in IA, which include permitted facilities, 

and other facilities that have voluntarily registered with DNR. Access to this database 

is located at https://programs.iowadnr.gov/animalfeedingoperations/Help.aspx

Kansas

Could not locate any CAFO information for Kansas. 
October 31, 2011, revised March 1, 2012 12

Missouri 

Missouri Department of Natural Resources maintains an interactive map of NPDES 

CAFOs plus any voluntarily registered AFOs. See http://dnr.mo.gov/env/wpp/afo.htm. 

A non-interactive map is found at http://www.dnr.mo.gov/env/wpp/cafo/cafos8x11.pdf

For further information, the Water Protection Program may be contacted at 573-751-

1300 or E-mail: cleanwater@dnr.mo.gov

Nebraska 

Nebraska Department of Environmental Quality (DEQ) maintains an interactive map 

for permitted facilities. The search options do not support identification of only 

permitted CAFOs under the NPDES program but the map does show the Livestock 

Waste Permitted Facilities. See http://deqims.deq.state.ne.us/DEQ/index.jsp.

EPA Region 9 

Arizona

A search of ECHO identified 14 permitted facilities. No other info found.

California 

ICIS lists only permitted CAFOs in CA, while PCS is listing both CAFOs and AFOs.

Many regions in CA have permitted CAFOS through waste discharge requirements 

instead of NPDES permits, so the number of permitted facilities is underestimated. 

Also found a list of all animal feeding operations regulated in California through 

CIWQS. 

Hawaii

Guidance provided on the state Department of Health Website states that as of 

January 2010, there are no CAFOs in Hawaii. See page 3 of 

http://hawaii.gov/health/environmental/environmental/water/wastewater/pdf/livestock.

pdf. 

EPA Region 9 indicates that there are 2 CAFOs in Hawaii. See 

http://www.epa.gov/region9/animalwaste/hawaii.html (last updated June 2011) 

Nevada

Could not locate any site specific information about CAFOs in Nevada. A search of 

EPA ECHO indicated that there are four permitted CAFOs in NV. 

EPA Region 10 

Alaska

Could not locate any CAFO information for Alaska. 

Idaho 

Could not locate any CAFO information for Idaho. EPA is the permitting authority, but 

works in conjunction with the Department of Agriculture.

Oregon

Found information for only a number of CAFOs in Oregon that were listed under a 

public notice. Whatever other CAFOs that are covered under the General Permit 

could not be identified.
October 31, 2011, revised March 1, 2012 15

The Department of Agriculture is the authorized agency to implement the NPDES 

discharge program for CAFOs, so ICIS/PCS data were not available. 

Washington 

Could not locate any CAFO information for Washington. The general CAFO permit is 

part of a split livestock program covered by an MOU with the Department of Ecology 

and Department of Agriculture. Ecology administers the permit and Agriculture 

provides inspections and technical assistance to CAFO permitted facilities and to 

dairies covered under the Dairy Nutrient Management Act. 

Comparison of CAFO Data Sources
