The Maryland Department of the Environment's AFO Division helps protect the Chesapeake Bay, local waterways, and our drinking water from nutrient pollution from Maryland's largest agricultural animal operations. The AFO Regulations and General Discharge (GD) Permit for AFOs are just one part of a comprehensive, statewide effort to address all sources of pollution that are impairing our waterways: wastewater treatment plants, industrial discharges, septic systems, urban/suburban stormwater runoff, and air emissions from power plants, vehicles, and trucks. If you need to contact the AFO Division, call 410-537-3314.
Please note that the 19AF permit requires additional information to be included in the CNMP in order for Maryland Department of the Environment to issue a permit. As stated in the GD Permit Part III.B.5 (p.13) and Parts IV.D.2-D.3 (p.23)- All new CNMPs must include this information, and for existing plans, the information can be attached as an addendum signed by the operator and the plan-writer.
The following additional information must be included in the CNMP:
NOI and Fee Reminder
According to state law and regulation, MDE is legally required to collect fees for Concentrated Animal Feeding Operations (CAFOs). In September 2019, MDE proposed draft regulations that would have reduced GD Permit fees for CAFOs, however, the Office of the Attorney General and a committee within the Maryland General Assembly recently informed MDE that it may not adopt its lower fee proposal. Due to these actions, the following fees will be applicable to CAFOs applying for the GD Permit:
CAFOs with Total House Capacity of 350,000 ft2 or More:
CAFOs with Total House Capacity of LESS than 350,000 ft2:
As notified previously, the deadline to submit a NOI and Comprehensive Nutrient Management Plan (CNMP) for coverage under the new GD Permit was September 6, 2020. CNMPs only need to be submitted with the NOI if MDE does not already have a current one on file. If you have not yet submitted your NOI and CNMP, please do so promptly. After these items are received, MDE will send you an invoice for the appropriate fee amount.
MDE is prohibited from issuing permit coverage under the new GD Permit until the applicable fee is paid. Please keep in mind, if you are an existing operation that was registered under the prior (14AF/AFA) GD Permit, and you submitted the Notice of Continued Operation (NOCO) form as well as your NOI and CNMP within the designated timeframes- you are still covered under the prior GD Permit
If you have any questions, please contact Mr. John Sullivan, Resource Management Program Manager, at (410) 537-3314 or email@example.com.

In accordance with Code of Maryland Regulations (COMAR) 26.08.04.09N(k), the following person(s) have requested that the Department conduct a public hearing regarding the Department's approval of the listed AFO(s)' required plan(s):
Notice is given that the Department will hold (a) public hearing(s) regarding the approval of the required plan(s) at 6:00 PM on the following date(s) and at the following location(s):
Once you have determined that you are a CAFO or a MAFO, you must submit to MDE a NOI Form. CAFOs and MAFOs are also required to submit a comprehensive nutrient management plan (CNMP) that is developed in accordance with the USDA-Natural Resources Conservation Service (NRCS) technical standards. The required plan(s) must comply with the requirements in COMAR 26.08.04.09N(3)(b) and federal regulations in 40 CFR 122.42(e). DO NOT WAIT UNTIL YOU GET YOUR REQUIRED PLAN(S) TO SEND IN YOUR NOI if you are required to have permit coverage. To apply for assistance in obtaining a CNMP, contact your local NRCS office. Assistance with NMPs or Conservation Plans can be obtained from your district office.
If you are a corporation, in order to obtain coverage under the GD Permit, you must be registered and in good standing with the Maryland Department of Assessments and Taxation (SDAT). The business or entity’s information provided in the NOI must match the information in the SDAT register.

Maryland's General Discharge Permit for Animal Feeding Operations (General Discharge Permit 09AF, MDG01) has been upheld as a valid general permit by the Maryland courts. This removes uncertainty for AFOs that the GD Permit is legally sufficient. All AFOs that meet the requirements for needing coverage under the GD Permit should submit an NOI and the required plans, if they have not already done so. See Letter I (below) for more information on the history of the GD Permit. This GD Permit was renewed on December 1, 2014.
All concentrated animal feeding operations (CAFOs) that are registered under the "General Discharge Permit for Animal Feeding Operations" are required to submit their CAFO/MAFO Annual Implementation Reports (AIR) by March 1st of every year covering the previous calendar year.
For the last several years, the Maryland Department of Agriculture (MDA) and the Maryland Department of the Environment (MDE) have consolidated their respective annual reports for AFOs. Applicable livestock and poultry farmers will receive one consolidated AIR Form from MDA. Once completed, this AIR Form should be mailed back to MDA, who will, in turn, forward the AFO AIRs to MDE.
If your operation is required to submit an AFO annual report and you have not received it, please contact your local MDA field office. These forms and instructions are also available on the MDA website, www.mda.maryland.gov. Follow the "Nutrient Management" link.
MDE has developed guidance on how to handle catastrophic poultry mortalities here. This document provides a summary of the regulations and practices to be used in cases where a large number of chickens have died due to excessive heat, fires, or disease. Mortalities must be composted in facilities designed for that purpose. If these cannot accommodate a catastrophic mortality, MDE must be notified and give permission to compost in other areas, such as in poultry houses or manure sheds.
MDE has established new "approved alternatives" to the 100-foot setback standards required of CAFOs and MAFOs. As required under Maryland's AFO regulations and permit, MDE consulted with the MDA, USDA-Natural Resources Conservation Service and the University of Maryland Extension in their deliberations in establishing these approved alternatives. The alternatives will give CAFOs and MAFOs additional practices to use during the development of a farm's comprehensive nutrient management plan or nutrient management plan for application of manure. The "Setback Requirements and Approved Alternatives" document describes these alternatives.
