SUBJECT: 2019 Annual Report Review
LP Corporation Roaring River Mill
Land Application and Distribution of Class A Residuals
Permit No. WQ0000461
Wilkes County
Dear Mr. Rhea:
The Division of Water Resources (DWR) acknowledges receipt of your 2019 Annual Report for
the subject permit. A review of this report was conducted by DWR staff person Justin Henderson.
While, review of the subject report mostly reflects compliance with Permit No. WQ0000461. The
following items of concern warrant your attention and action:
1) Field Summary Forms for application sites owned by Wilkes County Landfill, specifically
Tract 12, Field #5947 and Tract 21, Field #9513 either failed to specify or indicated "new
ground" as the target crop by which agronomic rates were calculated. Permit Condition
Part II. (10.) provides various options by which agronomic rates may be calculated, none
of which provide calculations associated with "new ground" and all of which require a
target crop be specified to determine expected nitrogen requirements based on Realistic
Yield Expectations (RYE). Please provide an explanation and/or justification for the PAN
rate associated with "new ground" and/or report the missing crop information by which the
Plant Available Nitrogen (PAN) rate was calculated for the above listed fields.
2) Non-compliance was reported on the Class A Annual Distribution and Marketing/Surface
Disposal Certification and Summary Form, related to exceedances of Groundwater
Standards [ 15A NCAC 02L .0202 (h) (111)] for Nitrate (NO3) in monitoring wells DS 1-
MW4, DS1-MW5, and DS1-MW9 for monitoring events conducted during calendar year
2019. The Permittee also indicated that this matter continues to be studied in conjunction
with the NCDEQ Aquifer Protection Section. Please provide an update of all findings and
if applicable, include any descriptions/detail of additional remediation/monitoring planned
to be conducted with projected schedules of implementation.
