7 CFR Part 810

RIN 0580-AA14


United States Standards for Corn

AGENCY: Grain Inspection, Packers and Stockyards Administration, USDA.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: In its periodic review of existing regulations, the Federal 
Grain Inspection Service (FGIS), a program of the Grain Inspection, 
Packers and Stockyards Administration (GIPSA), proposes to amend the 
U.S. Standards for Corn to: Report test weight (TW) to the nearest 
tenth of a pound, eliminate the count limit on stones and reduce the 
U.S. Sample grade aggregate weight tolerance from more than 0.2 percent 
by weight to more than 0.1 percent by weight, and offers stress crack 
testing as official criteria. This proposed rule is intended to 
facilitate the marketing of corn.

DATES: Comments must be submitted on or before April 24, 1995.

ADDRESSES: Written comments must be submitted to George Wollam, GIPSA, 
USDA, Room 0623-S, P.O. Box 96454, Washington, DC 30090-6454; FAX (202) 
720-4628.
    All comments received will be made available for public inspection 
at Room 0623 South Building, 1400 Independence Avenue, SW., Washington, 
DC during regular business hours (7 CFR 1.27(b)).

FOR FURTHER INFORMATION CONTACT: George Wollam, address as above, 
telephone (202) 720-0292.

SUPPLEMENTARY INFORMATION: 

Executive Order 12866

    This rule is exempt from Executive Order 12866 review.

Executive Order 12778

    This proposed rule has been reviewed under Executive Order 12778, 
Civil Justice Reform. This action is not intended to have a retroactive 
effect. the United States Grain Standards Act provides in Section 87g 
that no State or subdivision may require or impose any requirements or 
restrictions concerning the inspection, weighing, or description of 
grain under the Act. Otherwise, this proposed rule will not preempt any 
State or local laws, regulations, or policies, unless they present any 
irreconcilable conflict with this rule. There are no administrative 
procedures which must be exhausted prior to any judicial challenge to 
the provisions of this rule.

Regulatory Flexibility Act Certification

    James Robert Baker, Administrator, GIPSA, has determined that this 
proposed rule will not have a significant economic impact on a 
substantial number of small entities as defined in the Regulatory 
Flexibility Act (5 U.S.C. 602 et seq.) because most users of the 
official inspection and weighing services and those entities that 
perform these services do not meet the requirements for small entities. 
Further, the regulations are applied equally to all entities.

Background

    During October 1993, the Federal Grain Inspection Service (FGIS), 
prepared a discussion paper concerning the U.S. Standards for Corn. 
This paper addressed a number of issues relating to the standards and 
was distributed throughout the grain industry. The paper also served as 
a starting point for discussions with producers, trade associations, 
processors, handlers, and merchandisers to better understand their 
views on changes needed to improve existing standards. FGIS received 
positive feedback from the grain industry regarding the corn discussion 
paper; and, in fact, numerous industry representatives suggested that 
FGIS continue to develop and distribute similar documents before 
amending other standards.
    FGIS received a total of 12 written comments concerning the 
discussion paper: 3 from research associations and universities, 1 from 
a producer organization, 4 from handler and processor associations, 1 
from an industry consortium, 2 from grain inspection and weighing 
associations, and 1 from a grain company. In addition to receiving 
written comments, FGIS reviewed the corn standards with representatives 
of the Iowa Department of Agriculture, the Grain Quality Workshops, and 
other corn-related associations.
    On the basis of all comments and other available information, FGIS 
is proposing three changes to the corn standards that reflect current 
market needs and also serve to improve the effectiveness of the 
standards. The proposed amendments include: (1) Reporting TW to the 
nearest tenth of a pound, (2) eliminating the count limit on stones and 
reducing the U.S. Sample grade aggregate weight tolerance from more 
than 0.2 percent by weight to more than 0.1 percent by weight, and (3) 
offering stress crack testing as official criteria.

Test Weight (TW)

    FGIS proposes to revise Sec. 810.102(d) of the United States 
Standards for Grain to report TW in corn to the nearest tenth of a 
pound. This change will bring the reporting requirement for TW into 
line with the reporting requirements for other factors, such as total 
damaged kernels and broken corn and foreign material (BCFM).
    This is not the first time that FGIS has proposed to revise the 
reporting requirement for TW in corn. In 1986, (51 FR 35224) to promote 
greater uniformity among the grain standards, FGIS proposed to reformat 
the grain standards and solicited comments regarding certification 
requirements for factors not expressed to the nearest tenth. FGIS 
proposed to report all percentages (except ergot) and all TW values to 
the nearest tenth. The proposal included TW in corn which is certified 
in whole and half pounds with fractions of a half pound disregarded.
    The majority of commentors who opposed the proposal indicated that 
sufficient data were not available to determine how a change in 
reporting requirements would affect reproducibility of results--
especially for TW in coarse grains. FGIS decided not to revise the 
reporting requirements, except for dockage in wheat (52 FR 24414). FGIS 
does offer, upon request, the recording of TW results to the nearest 
tenth pound in the Remarks section of the grade 
certificate. [[Page 9791]] 
    An extensive review of FGIS grain inspection and monitoring data, 
which represent over 4,200 samples, provides standard deviation values 
for each of the mandatory factors across all grade levels within the 
corn standards. Standard deviation is a measure of variation; and a 
particular type of standard deviation, the standard deviation of the 
difference (SDD), can be used as a measure of reproducibility. When a 
sample is reanalyzed for a particular factor, the reproducibility of 
results improves as the SDD becomes smaller.
    The review of inspection data resulted in separate SDD values for 
each grade level for both domestic and export corn samples. Only the 
export SDD values, however, were calculated from raw TW data reported 
to the nearest tenth of a pound. Comparison of SDD values between 
factors will therefore focus on the export values. For TW, the SDD 
value was the same, 0.366, for all grade levels, thus indicating an 
insignificant range and a consistent reproducibility in TW values 
across all grade levels. For damaged kernels total (DKT), the SDD 
values ranged from 0.853 to 1.814 for U.S. Grade Nos. 1 to 5. For BCFM, 
the corresponding values ranged from 0.197 to 0.359 for U.S. Grade Nos. 
1 to 5. The range in SDD values reflects the range in DKT and BCFM 
levels and the variance in the reproducibility of results across grade 
levels.
    The TW SDD values are either close to or lower than the SDD values 
for the other factors when all raw data used in the calculation of the 
SDD values had been reported to the nearest tenth. It can be inferred 
from SDD values that the reporducibility of TW results is similar to or 
better than the reproducibility of DKT and BCFM results. The industry 
accepts the current practice of reporting DKT and BCFM results to the 
nearest tenth. Therefore, based on the comparison of SDD values, the 
industry may also find the reporting of TW to the nearest tenth of a 
pound acceptable.
    Another consideration for the industry is that virtually all TW 
results are currently rounded down. For example, under the current 
reporting method, a scale reading 53.99 pounds per bushel is certified 
as 53.5 pounds per bushel which would meet the TW grade limit for U.S. 
No. 3 corn. If the results, however, were rounded to the nearest tenth 
of a pound, the resultant 54.0 pounds per bushel would meet the grade 
limit for U.S. No. 2 corn. In general, the current practice of rounding 
down causes TW to almost always be underrepresented throughout the 
marketing channel. Furthermore, the rounding of TW results to the 
nearest tenth of a pound will not significantly affect the assigned 
grade, since in most cases the rounded result will fall within the 
grade requirement.

Stones

    FGIS proposes to eliminate the count limit on stones and reduce the 
aggregate weight tolerance from more than 0.2 percent by weight to more 
than 0.1 percent by weight. Stones have a harmful effect on corn 
quality and milling. Several industry representatives have requested 
that the count limit on stones be eliminated and the aggregate weight 
tolerance be reduced from more than 0.2 percent by weight to more than 
0.1 percent by weight. The elimination of the count limit would serve 
to further tighten the tolerance of stones by allowing a smaller number 
of heavy stones to downgrade a sample.

Stress Crack Testing

    FGIS proposes to offer corn stress crack (SC) testing as official 
criteria under the United States Grain Standards Act. This testing 
service will be optional and FGIS will recover the cost of providing 
this service through the applicable inspection fees as set forth in 
section 800.71(a) of the regulations.
    Corn kernels which contain stress cracks tend to break apart, and, 
as a result, are undesirable in the corn dry milling, wet milling, and 
food manufacturing processes. In the dry milling process, cracked 
kernels yield lower percentages of large flaking grits which are the 
highly valued prime product (ref. 1). Starch recovery, which is an 
essential component of the wet milling process, is also lower from 
kernels possessing numerous stress cracks. To the food manufacturer, 
stress cracks are of concern because of the adverse effect on soaking 
which is an essential component of the manufacturing process. Some 
snack food companies currently limit the percent of kernels with stress 
cracks to values less than 20 percent (ref. 2). Cracked corn is also 
more difficult to store than undamaged corn, since cracked corn is more 
readily attacked by microorganisms and is difficult to aerate 
uniformly.
    Cracked corn could also contribute to increased elevator dust 
levels and, thus, negatively impact elevator safety.
    Commentors addressed the various detrimental effects of stress 
cracks and broken corn, and the majority of commentors recommended that 
FGIS offer stress crack testing as part of the national inspection 
service. Due to the importance of stress crack testing, GIPSA proposes 
to offer stress crack testing, upon request, as official criteria. 
GIPSA and the official agencies of the national inspection system will 
use the method recommended by the Illinois Crop Improvement 
Association's Identity Preserved Grain Lab (IPGL) which performs stress 
crack tests on over 4,000 corn samples per year. FGIS will use this 
method because it is cost-effective, easy to use, and quick.
    As described by the IPGL, stress crack tests are performed on 
random subsamples of 100 kernels. The kernels are inspected visually on 
a back lighting lightboard and separated into four categories: no or 
zero stress cracks, and more than two or multiple stress cracks. The 
percentage of kernels falling into each category is used to calculate 
the percentage of stress cracks and a stress crack index as follows:

% TSC = [% single SC + % double SC + % multiple SC]
SCI = [(% single SC) + (% double SC  x  3) + (% multiple SC  x  5)]
where SC = stress cracks, SCI = stress crack index,
and TSC = total stress cracks

    The stress crack index is an indication of the multiplicity of 
stress cracks in each kernel. The weighting factors indicate that corn 
kernels with double and multiple stress cracks are more susceptible to 
breakage than kernels with single stress cracks.
    FGIS seeks comments not only on the proposal to offer stress crack 
testing as official criteria but on the reporting method for results. 
Since the information will be readily available, commentors should 
address whether the percentage of stress cracks in each of the three 
categories, single, double, and multiple, should, be reported. If no 
comments are received on the reporting method, FGIS will report only 
the total percent of stress cracks and the stress crack index.

Miscellaneous Changes

    FGIS proposes to revise the format of the grade chart in 
Sec. 810.404, Grades and grade requirements for corn, to improve the 
readability of the grade chart.

Proposed Action

    FGIS proposes to revise Sec. 810.102, Definition of other terms, by 
revising section (d), Test weight per bushel. It is proposed that TW in 
corn be reported to the nearest tenth of a pound.
    FGIS proposes to revise Sec. 810.404, Grades and grade requirements 
for corn, by revising the definition of U.S. Sample grade by 
eliminating the count limit on stones and reducing the aggregate weight 
criteria from more than 0.2 percent by weight to more than 0.1 percent 
by weight.
    Comments including data, views, and arguments are solicited from 
interested [[Page 9792]] persons. Pursuant to Section 4(b)(1) of the 
United States Grain Standards Act, as amended (7 U.S.C. 76(b)(1)), upon 
request, such information concerning changes to the standards may be 
orally presented in an informal manner. Also, pursuant to this section, 
no standards established or amendments or revocations of standards are 
to become effective less than one calendar year after promulgation 
unless, in the judgement of the Administrator, the public health, 
interest, or safety require that they become effective sooner.
