area of the trash stacker system. The owner or operator shall keep the
trash material wet and compost it in place until the material is
removed from the dump area for additional composting or disposal.
ii. Gin Yard- The owner or operator shall clean and dispose of accumulations of
trash or lint on the non-storage areas of the gin yard daily.
iii. Traffic areas - The owner or operator shall clean paved roadways, parking,
and other traffic areas at the facility as necessary to prevent re-entrainment of
dust or debris. The owner or operator shall treat unpaved roadways, parking,
and other traffic areas at the facility with wet or chemical dust suppressant as
necessary to prevent dust from leaving the facility's property and shall install
and maintain signs limiting vehicle speed to 10 miles per hour where
chemical suppression is used and to 15 miles per hour where wet suppression
is used.
iv. Transport of Trash Material - The owner or operator shall ensure that all
trucks transporting gin trash material are covered and that the trucks are
cleaned of over-spill material before trucks leave the trash hopper dump area.
The dump area shall be cleaned daily.
e. Monitoring
i. The owner or operator of each ginning operation shall install, maintain, and
calibrate monitoring devices that measure pressure, rates of flow, and other
operating conditions necessary to determine if the control devices are
functioning properly.
ii. Baseline Studies - The owner or operator of each gin shall ensure air flows
(air velocities) of the entire dust collection system, without cotton being
processed, are within the design range for each collection device. For 2D-2D
cyclones the air flow(air velocity) design range is 2700 to 3600 feet per
minute. For ID-3D cyclones the design range is 2800 to 3600 feet per
minute. For other control devices the air flow design range is that found in
the manufacturer's specifications. The assurance of these air flows shall be
based on an initial baseline study conducted by the owner or operator and any
additional baseline studies conducted thereafter. During the initial and all
additional baseline studies, the owner or operator shall measure or determine
according to the methods specified in this Paragraph and record in a logbook:
A. the calculated inlet velocity for each control device; and
B. the pressure drop across each control device (this will be the static
pressure provided that the control device releases to the atmosphere).
The owner or operator shall use Method 1 and Method 2 of 40 CFR Part 60
Appendix A to measure flow(duct velocity) and static pressure and
determine inlet velocity or the USDA method for determining duct velocity
and static pressure in Agricultural Handbook Number 503, Cotton Ginners
Handbook. The Cotton Ginners Handbook method shall only be used where

Registration No. 2100067X00
Page 5
test holes are located a minimum of eight and one-half pipe diameters
downstream and one and one-half diameters upstream from elbows, valves,
dampers, changes in duct diameter or any other flow disturbances. Where
Method 2 is used a standard pitot tube may be used in lieu of the s-pitot
specified in Method 2 subject to the conditions specified in Paragraph 2.1 of
Method 2.
iii. Monthly Static Pressure Checks and Corrective Action- On a monthly basis
following the initial baseline study or the new season flow range verification
measurements, the owner or operator shall measure and record in the logbook
the static pressure at each port where the static pressure was measured in the
baseline study. Measurements shall be made using a manometer, a
magnahelic gauge, or other device that the director has approved as being
equivalent to a manometer. If the owner or operator measures a change in
static pressure of 20 percent or more from the measured in the baseline study,
the owner or operator shall initiate corrective action. Corrective action shall
be recorded in the logbook. If corrective action will take more than 48 hours
to complete, the owner or operator shall notify the regional supervisor of the
region in which the ginning operation is located as soon as possible,but by
no later than the end of the day such static pressure is measured.
iv. Season Startup Flow Range Verification Measurement -No later than the
first week of operation of each new season, the facility shall perform air flow
verification measurements, without cotton being processed, and record all
results in a logbook. If the owner or operator measures a change in static
pressure of 20 percent or more from that measured in the baseline study, the
owner or operator shall initiate corrective action. Corrective action shall be
recorded in the logbook. If corrective action will take more than 48 hours to
complete, the owner or operator shall notify the regional supervisor of the
region in which the ginning operation is located as soon as possible,but by
no later than the end of the day such static pressure is measured. This
measurement will serve as the first monthly measurement of the new season.
V. New Baseline Studies - When any design changes to the dust control system
are made, the owner or operator shall conduct a new baseline study for that
portion of the system and shall record the new values in the logbook required
in Paragraph(f). Thereafter monthly static pressure readings for that portion
of the system shall be compared to the new values.
vi. Daily inspections for Structural Integrity - During the ginning season, the
owner or operator shall daily inspect for structural integrity of the control
devices and other emissions processing systems and shall ensure that the
control devices and emission processing systems conform to normal and
proper operation of the gin. If a problem is found, corrective action shall be
taken and recorded in the logbook required in Paragraph (f).
vii. At the conclusion of the ginning season, the owner or operator shall conduct
an inspection of the facility to identify all scheduled maintenance activities
and repairs needed relating to the maintenance and proper operation of the air

Registration No. 2100067X00
Page 6
pollution control devices for the next season. Any deficiencies identified
through the inspection shall be corrected before beginning operation of the
gin for the next season.
f. Recordkeeping - The owner operator shall establish and maintain on-site a logbook
documenting the following items:
i. Results of the baseline study as specified in Paragraph(e)(ii);
ii. Results of monthly static pressure checks and any corrective action taken as
specified in Paragraph(e)(iii);
iii. Results of season startup flow range verification measurements and any
corrective action taken as specified in Paragraph(e)(iv);
iv. Results of new baseline studies as specified in Paragraph (e)(v);
V. Observations from daily inspections of the facility and any resulting
corrective actions taken as required in Paragraph (e)(vi); and
vi. A copy of the manufacturer's specifications for each type of control device
installed.
