M/hat Are the Federal Requirements for
Dairy Cow and Heifer CAFOs?
In December 2002, EPA revised the Clean Water
Act regulation for Concentrated Animal Feeding
Operations, or CAFOs. If you own or operate a
dairy cow or heifer CAFO, you must apply for a
permit. This pamphlet gives general information
about what your permitting authority might
require in your CAFO's permit.

Is my dairy cow or heifer operation a
CAFO?
Your operation is a CAFO
if it is an animal feeding
operation (AFO) and it
meets one of the following
conditions
5ee the pamphlet
Will My Operation
Be Regulated? for
the definition of
an AFO.
Large CAFOs
Your dairy cow or heifer AFO is a Large CAFO if it has
at least
•S 700 dairy cows
S 1,000 heifers
Medium CAFOs
Your dairy cow or heifer AFO is a Medium CAFO if it has
at least
•S 200 dairy cows
300 heifers
and
•S a man-made ditch or pipe carries manure
or wastewater from your operation or
•S your animals come into contact with surface
water running through the area where they're
confined
Designated CAFOs
No matter what size your operation is, if it is an AFO, it
can be designated a CAFO. If your permitting authority
inspects your operation and finds that it's adding
pollutants to surface waters, your operation might need
a CAFO permit.
My operation is a CAFO. What do I
have to do?
You must apply to your permitting authority for a
permit. Most states have the authority to manage
CAFO programs and issue permits. 5tate CAFO
programs are based on the revised national regulation.
You can use this pamphlet to help you learn about
the minimum requirements for a permit. You should
contact your permitting authority to find out what your
state-specific requirements are and how to apply for
a permit. Check the insert to this pamphlet for your
permitting authority's contact information.
What will my operation's permit require?
Your CAFO permit will require you to meet certain
conditions for your production
and land application areas. The
specific requirements of your
permit will depend on whether
your operation is a Large,
Medium, or designated CAFO.
The production area
is the area where
your animals are
housed and manure
is stored.
Requirements for all dairy cow or heifer CAFOs
You can expect your permit to require you to
•S Implement a nutrient management plan
•S 5ubmit annual reports to your permitting authority
•S Keep your permit current until you completely close
your operation and remove all manure
•S Keep records of your nutrient management
practices for at least 5 years (5ee the pamphlet
What Are the Federal Record-Keeping and Reporting
Requirements?)
Nutrient management plans for all dairy cow and
heifer CAFOs must include provisions for
•S Assuring adequate manure storage capacity
•S Proper handling of dead animals and chemicals
•S Diverting clean water from the production area
•S Keeping animals out of surface water
•S Using site-specific
conservation practices
The land application
area includes all
the land under your
control where you
spread manure.
•S Developing ways to test
manure and soil
•S Assuring appropriate
use of nutrients when
you spread manure
•S Keeping records of your nutrient management practices
Your permitting authority might set more
requirements for any size CAFO.
Requirements for Medium and designated dairy
cow or heifer CAFOs
Your permitting authority might set more requirements for
your nutrient management plan. These requirements will
depend on the permit writer's best professional judgment
and could be like the requirements for Large dairy cow or
heifer CAFOs.
Requirements for large dairy cow or heifer CAFOs
Nutrient management plans for Large dairy cow or heifer
CAFOs have more requirements for production and land
application areas.
Production area
•/ Design your production area to contain all of your
CAFO's manure plus the runoff from a 25-year,
24-hour rainfall event (large storms). (Overflows from
large storms are allowed only if your operation is
designed and operated to meet these specifications.)
•/ Install depth markers in liquid manure storage
structures
•/ Inspect your production area weekly and all water
lines daily
•S Correct any problems you find as soon as possible
•S Properly handle dead animals
Land application area
•S Apply manure at rates that meet your permitting
authority's standards
•S Analyze manure for
nutrient content at least
once a year
•S Analyze the soil from
your land application
fields for phosphorus
amounts every 5 years
•S Avoid applying manure to
any land within 100 feet
of surface water
•S From time to time, inspect your land application
equipment for leaks
Transferring manure to other persons
•S Keep records for at least 5 years on the date,
recipient, amount, and nutrient content of the
manure you transferred
•S Information about the nutrient content of your
manure must be given to the recipient
5ome Large dairy cow
or heifer CAFOs may
qualify for equivalent
discharge allowances.
If you use innovative
technologies, like
treating wastewater in
your production area,
ask your permitting
authority about your
options.
