A. Staging is the placement of biosolids on a
					 permitted land application field, within the land application area, in
					 preparation for commencing land application or during an ongoing application,
					 at the field or an adjacent permitted field. Staging is not considered storage
					 and shall not take the place of storage.
B. Staging requirements.
1. Staging of biosolids shall not commence
					 unless the field meets the requirements for land application in accordance with
					 Part IX (9VAC25-32-303 et seq.) of this
					 regulation and field conditions are favorable for land application;
2. Biosolids may be staged for up to seven
					 days from the first day biosolids are offloaded onto the staging area, with the
					 following exceptions:
a. In areas of Karst
					 topography, biosolids offloaded at a permitted land application field shall be
					 land applied by the end of the business day;
b. In areas identified in the USDA soil
					 survey as frequently flooded, biosolids offloaded at a permitted land
					 application field shall be land applied by the end of the business day;
					 or
c. Biosolids shall not be staged
					 overnight on sites that have on-site storage;
3. If staged biosolids cannot be spread by
					 the end of the seventh day of staging, the permittee shall take the following
					 actions:
a. Biosolids shall be covered to
					 prevent contact with precipitation;
b. The permittee shall notify the department
					 in writing within 24 hours. Notification shall include the biosolids source or
					 sources and amounts, location of the site, and reason for staging biosolids
					 longer than seven days; and
c.
					 Biosolids that have been staged for greater than seven days shall be spread or
					 removed from the field as soon as field conditions become favorable for land
					 application;
4. Staging
					 shall be limited to the amount of biosolids specified in the nutrient
					 management plan to be applied at the intended field;
5. Biosolids will be staged within the land
					 application area of the field in which the biosolids will be applied or in a
					 permitted field adjacent to the subject field, in a location selected to
					 prevent runoff to waterways and drainage ditches;
6. Biosolids shall not be staged in the
					 setback areas;
7. Biosolids shall
					 not be staged overnight within 400 feet of an occupied dwelling unless reduced
					 or waived through written consent of the occupant and landowner;
8. Biosolids shall not be staged overnight
					 within 200 feet of a property line unless reduced or waived through written
					 consent of the landowner;
9.
					 Management practices, as described in the biosolids management plan, shall be
					 utilized as appropriate to prevent pollution of state waters by staged
					 biosolids;
10. Staged biosolids are
					 to be inspected by the certified land applier daily. After precipitation events
					 of 0.1 inches or greater inspections shall ensure that runoff controls are in
					 good working order. Observed excessive slumping, erosion, or movement of
					 biosolids is to be corrected within 24 hours. Any ponding at the site is to be
					 corrected and any malodor shall be addressed in accordance with the odor
					 control plan. The certified land applier shall maintain documentation of the
					 inspections of staged biosolids; and
11. Staged biosolids shall be managed so as
					 to prevent adverse impacts to water quality or public health.
