| Applicability: |
eCFR Subpart DD  [ecfr.gov]
This subpart applies to:
- Grain terminal elevators and grain storage elevators that commence construction, modification or reconstruction after Aug 3, 1978.
Affected facilities:
- Truck loading or unloading stations;
- Barge and ship loading or unloading stations;
- Railcar loading or unloading stations;
- Grain dryers;
- Grain handling operations.
Definition of "Grain terminal elevator"
- Any grain elevator which has a permanent storage capacity of more than 2.5 million U.S. bushels, except those located at animal food manufacturers, pet food manufacturers, cereal manufacturers, breweries, and livestock feedlots.
Definition of "Grain storage elevator"
- Any grain elevator located at any wheat flour mill, wet corn mill, dry corn mill (human consumption), rice mill, or soybean oil extraction plant which has a permanent storage capacity of 1 million bushels.
Modifications (by themselves) do not include:
- Addition of gravity loadout spouts to existing grain storage or grain transfer bins.
- Installation of automatic grain weighing scales.
- Replacement of motor and drive units driving existing grain handling equipment.
- Installation of permanent storage capacity with no increase in hourly grain handling capacity.
If permanent storage capacity increases over the applicability threshold (previous existing storage capacity below threshold), then only the affected facilities that were added or modified are subject to this subpart. Sources should document which affected facilities were added or modified due to the installation of storage capacity.
