 On December 16, 2009 the Environmental Protection Agency (EPA) finalized emissions
limits for toxic air pollutants from prepared feeds manufacturing facilities. Toxic air
pollutants, or air toxics, are known or suspected to cause cancer, other serious health
problems and environmental damage.
 This rule applies to prepared feeds manufacturing area sources that produce animal (not
including cat and dog) feed products and use chromium compounds or manganese
compounds. Area sources emit less than 10 tons per year of a single air toxic, or less than
25 tons per year of a mixture of air toxics.
 All facilities that are subject to the rule will be required to apply management practices in
areas of the facility where materials containing chromium or manganese are stored, used,
or handled. In addition, facilities with an average daily feed production level of more than
50 tons per day will be required to have control equipment to reduce emissions from one
specific operation (pelleting/pellet cooling).
 Compliance provisions in the rule include requirements for notifications, recordkeeping,
and reporting. Within 120 days of the effective date of the final rule, each facility is
required to submit an Initial Notification to EPA containing basic information about the
facility and its operations.
 For demonstrating ongoing compliance, the requirements include daily, monthly,
quarterly, and annual inspections and certifications that the management practices are
being followed and the control equipment is operating properly.

 There are approximately 1,800 facilities in the prepared feeds manufacturing source
category, most of which are small businesses. EPA believes that prepared feeds
manufacturing facilities already implement the required management practices, so there
will be no additional costs for these measures. Costs for notifications, recordkeeping, and
reporting are estimated to be $1.7 million/year, or about $980/facility.
 EPA estimates that 26 of the facilities with an average daily feed production level of
more than 50 tons per day will be required to install control equipment at a nationwide
cost of about $2.5 million. Annual costs nationwide are estimated to be just over $3
 Compliance with this rule will result in estimated emission reductions of around 1,100
tons/year of particulate matter (PM), 100 tons/year of PM2.5, and around 20 tons/year of
manganese and chromium emissions.
 EPA is exempting chemical preparation facilities that would be covered by this rule from
obtaining title V permits, which are federal operating permits. After a comprehensive
evaluation, the agency found that:
– the exemption for these facilities would not adversely affect public health, welfare, or
the environment because the level of emissions control would be the same if a title V
permit were required
– there are implementation and enforcement programs in place that would ensure
compliance with the final standards without relying on a title V permit, and
– requiring title V permits will be unnecessarily burdensome with regard to cost and
technical resources on these smaller industrial facilities.

 The Clean Air Act requires EPA to identify categories of sources that emit one or more of
the 188 listed hazardous pollutants. These categories include both major and area
 Major sources of air toxics emit 10 tons per year of a single air toxic or 25 tons per year
of a mixture of air toxics. Examples include chemical plants and steel mills. Area
sources release smaller amounts of toxic pollutants into the air—less than 10 tons per
year of a single air toxic, or less than 25 tons per year of a mixture of air toxics.
Examples include neighborhood dry cleaners and gas stations. Though emissions from
individual area sources are often relatively small, collectively their emissions can be of
concern—particularly where large numbers of sources are located in heavily populated
 The Clean Air Act requires EPA to identify the toxic air pollutants that pose a health
threat in the largest number of urban areas and to regulate sufficient area source
categories to ensure that the emissions of these “urban” air toxics are reduced. EPA
implements these requirements through the Integrated Urban Air Toxics Strategy.
 The prepared feeds manufacturing source category in today’s rule is included on the area
source category list.
 For area sources within each source category, the Clean Air Act allows EPA to develop
standards or requirements which provide for the use of generally available control
technologies or management practices (GACT) rather than the maximum achievable
control technology (MACT) required for major sources.
