State and federal agencies are implementing stronger nutrient regulatory laws including
equine operations. Nationwide, equine numbers have increased by 77% since 1997; and
there are 9.5 million horses in the United States (AHC, 2005). All horse farms are covered
under the Federal Animal Feeding Operation (AFO) and these laws are regulated through the
Environmental Protection Agency (EPA); state requirements may be more stringent than
federal. Pennsylvania requires any farm housing animals to write a Manure Management
Plan, regulated by Department of Environmental Protection, and kept on file at the farm and
doesn’t need to be approved, unless it is a Concentrated Animal Operation (CAO) or
Concentrated Animal Feeding Operation (CAFO). New Jersey requires facilities with as few
as 8 animal units (AU) to develop animal waste management plans. The rule is tiered with
larger farms (> 300 AU) having to complete a certified nutrient management plan, farms of 8-
299 AU complete a self-certified plan, and the smallest farms (< 8 AU) complete no plan. In
Delaware one horse equals 1.25 AU; properties with seven or more horses must comply. The
Virginia Department of Conservation and Recreation manages agricultural nutrients found in
fertilizers, manure, and focus on BMPs, P-Index management. VA defines AFOs as 150
horses, kept in confinement for 45 days/yr. In 2010, West Virginia Department of Agriculture
established the nutrient management certification program for equine. Maryland’s Water
Quality Improvement Act, affect horses in 2004; horse operation making $2,500 gross annual
income or houses 8 AU's must file plans. Farms with 75 horses are subject to state
permits. Kentucky’s 1998 Act requires operation with 14 contiguous acres develop a
plan. Twenty-five states administer a state NPDES, CAFO Program with other state permit
program.
ABSTRACT
• Governmental agencies are concerned about non-point sources of pollution and have
focused on agriculture as a major contributor to water quality issues. Equine operations are
now included in these regulations. Many state’s laws have regulated equine farms requiring
farm managers to incorporate conservation practices.
• Federal law states that equine operations with at least 500 head of horses that are in
confinement for 45 days (nonconsecutive) over a 12 month period are considered a CAFO.
State requirements may be more stringent than the federal requirement. A specific farm
operation's requirements are spelled out in their permit and it is against those requirements
that the state and EPA will inspect an operation and evaluate compliance.
• In some states a horse farm may be regulated by more than one agency. Each horse farm
should have a plan for managing manure, pastures and mud. Agencies are focusing on
equine operations because of the large number of high density farms.
• Chesapeake Bay Executive Order to reduce the amount of nitrogen and phosphorus
entering the Chesapeake Bay has impacted agriculture.
INTRODUCTION
STATE’S EQUINE NUTRIENT MANAGEMENT REGULATIONS --- SURVEY RESULTS
Pennsylvania is a state that has more than one regulation. In 2011, any farm that houses one
animal in the state of Pennsylvania will have to have a written Manure Management Plan,
meeting the guidelines provided in the PA Department of Environmental Protection’s Manure
Management Manual. The plan needs to be kept on file at the farm and doesn’t need to be
approved, unless the farm is a Concentrated Animal Operation (CAO) 8 AU & acreage limit,
or Concentrated Animal Feeding Operation (CAFO) (> 500 AU).
Arkansas Federal Animal Feeding Operation (AFO/CAFO) Regulation are regulated through
the Environmental Protection Agency (EPA). Nutrient management planning is mandatory in
many instances, record keeping and developed by a certified planner. A farm has to have at
least 500 horses, must be in confinement for 45 days (nonconsecutive) over a 12 month
period. Some horse farms may be eligible for federal financial incentive programs,
Environmental Quality Incentives Program (EQIP). Farms located in identified nutrient-
sensitive areas of the state may be required to do more regulation due to Arkansas Acts 1059
and 1061, took effective in 2004.
Virginia The Virginia Department of Conservation and Recreation works to manage both
urban and agricultural nutrients found in fertilizers, manure, municipal sewage sludge and
other sources. Regulations focus on manure management, BMPs, P-Index management,
and VA has a “no discharge” permit requirement. The state regulates animal feeding
operations and defines them as150 horses, 300 slaughter steers or 200 dairy cattle; and are
kept in confinement for 45 days, over a 12 month period.
New Jersey The New Jersey Department of Agriculture coordinates the Animal Waste
Management Regulations that requires facilities with as few as 8 animal units (AU = 1000 lb.
of animal) to develop animal waste management plans. Agricultural management
professionals in New Jersey assist livestock operations in preparing environmentally
responsible animal waste management plans. The rule has a tiered approach with only
larger farms (>300 AU) having to complete a fully certified nutrient management plan. The
farms have more than 8 AU will complete a self-certified plan. The smallest farms (< 8 AU)
will not be required to complete any plan; however, they are encouraged to do so.
Delaware Delaware's law dictates that anyone with 8 AUs have a waste management plan,
which provides specific guidelines about where and how to store manure and document what
is done with it. In Delaware, one horse equals 1.25 AUs, so only properties with seven or
more horses must comply. Also, if fertilizer is applied to 10 or more acres, one must have a
nutrient management plan. (DE, DOA, 2011)
STATE NUTRIENT MANAGEMENT REGULATIONS
Equine operations are treated differently among the various states. In some states a horse farm may be
regulated by more than one agency. However, horse farms should have a conservation plan to
manage manure, pastures and mud. In some states, state requirements may be more stringent than
the federal requirement. Therefore, farm managers should be aware of their state’s nutrient
management law(s)!

OBJECTIVE
Maryland In 1998 the Water Quality Improvement Act, took effect and horses were included July of
2004. The regulatory agency is the Maryland Department of Environment (MDE). However, in addition
Maryland will also be regulated under the EPA Chesapeake Bay TMDL. Under the Water Quality
Improvement Act, horse operations that make $2,500 gross annual income or house 8 AU's are
required to file a plan.
North Carolina North Carolina 1993 developed its own water quality permitting program through the
N.C. Division of Water Quality (DWQ), Department of Environmental & Natural Resources (DENR).
Facilities are subject to state permits if they include 75 head of horse (or 100 confined cattle) in the
operation.
Kentucky Water Quality Act 1998 requires a plan be developed for any operation with land base of 14
contiguous acres. Twenty-five states administer a state NPDES CAFO Program with some other state
permit, license, or authorization program. In most cases, this additional state authorization is a
construction or operating permit.
Twenty-five states administer a state NPDES CAFO Program with some other state permit, license, or

Objective was to summarize nutrient management regulations in the “Eastern States” as
determined by phone surveys of agencies and university extension specialists.
