Section 112 (c)(3) of the CAA directs
the Administrator to regulate area source categories accounting for
90 percent of the 30 listed urban hazardous air pollutants (HAP).
Prepared feeds manufacturing was listed pursuant to the Integrated
Urban Air Toxics Strategy Area Source Category List. The prepared
feeds manufacturers potentially affected by the rule are facilities
that produce feeds for large and small animals (except dogs and
cats) and are covered under the North American Industrial
Classification System (NAICS) code 311119. Regulation of this
source category is necessary to ensure that area sources
representing 90 percent of the emissions of chromium compounds and
manganese compounds are subject to regulation. For prepared feeds
facilities, the pelleting and pellet cooling operations are the
primary sources of these HAP metal emissions. Section 112(d)(5)
allows EPA to promulgate standards for area sources based on the
maximum achievable control technology or generally available
control technology or management practices (GACT). The standards
for this source category are based on GACT. This final rule applies
to all new and existing facilities that use chromium compounds and
manganese compounds in their processes. We are subcategorizing
facilities based on differences in production levels. Facilities
with an average daily feed production rate exceeding 50 tons per
day are "large" facilities, and those with an average daily feed
production rate of 50 tons or less per day are "small" facilities.
GACT consists of general management practices that apply in areas
of the facilities where HAP are stored, used, or handled. For
pelleting and pellet cooling operations in large facilities, GACT
is the installation of cyclones. We are using particulate matter
(PM) as a surrogate for chromium compounds and manganese compounds
given that a correlation exists between PM and these compounds such
that it is appropriate to rely on PM as a surrogate for these HAP
and for their control.
EPA is under court order to
promulgate standards for area sources. This increase results from a
new area source rule 40 CFR part 63, subpart DDDDDDD under section
112 of the Clean Air Act.
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
with 5 CFR 1320.9 and the related provisions of 5 CFR
1320.8(b)(3).

the proposed collection of information, that the certification
covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a
benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control
number;
If you are unable to certify compliance with any of
these provisions, identify the item by leaving the box unchecked
