.0108(b)(1)]
12. If land application sites are to be over -seeded or double -cropped (e.g., bermuda grass in the summer
and rye grass in the winter with both crops to receive residuals), then the second crop can receive an
application of PAN at a rate not to exceed 50 pounds per acre per year (lbs/ac/yr). This practice may
be allowed as long as the second crop is to be harvested or grazed. If the second crop is to be planted
for erosion control only and is to be tilled into the soil, then no additional PAN shall be applied. [15A
NCAC 02T ,0108(b)(1)]

Resource Conservation Service; a North Carolina Licensed Soil Scientist; or an agronomist. The
recommendations shall address the sodium application rate, soil amendments (e.g., gypsum, etc.), or a
mechanism for maintaining site integrity and conditions conducive to crop growth. The Permittee
shall maintain written records of these recommendations and details of their implementation. [15A
NCAC 02T.0108(b)(1)]
14. These residuals land application sites were individually permitted on or after December 30, 1983;
therefore, the compliance boundary is established at either 250 feet from the residual land application
area, or 50 feet within the property boundary, whichever is closest to the residual land application
area. An exceedance of groundwater standards at or beyond the compliance boundary is subject to
remediation action according to 15A NCAC 02L .0106(d)(2) as well as enforcement actions in
accordance with North Carolina General Statute 143-215.6A through 143-215.6C. Any approved
relocation of the COMPLIANCE BOUNDARY will be noted in Attachment B. [15A NCAC 02L
.0107(a)]
15. The review boundary shall be established midway between the compliance boundary and the residual
land application area. Any exceedance of groundwater standards at the review boundary shall require
action in accordance with 15A NCAC 02L .0106. [15A NCAC 02L .0108]
III. OPERATION AND MAINTENANCE REQUIREMENTS
The residuals management program shall be properly maintained and operated at all times. The
program shall be effectively maintained and operated as a non -discharge system to prevent any
contravention of surface water or groundwater standards. [15A NCAC 02T .1110]
2. The Asheville Regional Office, telephone number [phone], and the appropriate local
government official (i.e., county manager, city manager, or health director) shall be notified at least
