Item IV B.
Pesticides and fertilizers are applied to the row crop fields for production of cotton and
soybeans as needed. Some gravel lots, gravel roads, fence lines, building perimeters,
and drainage canals are treated with US EPA and North Carolina approved herbicides
applied according to the label at a frequency of approximately once or twice per year
depending on the regrowth and label instructions. Similarly, herbicides are applied to
small portions of the irrigation reservoir approximately twice per year using a spot
treatment foliar manner to control nuisance plants. Algaecides are applied to the
irrigation reservoir approximately two to four times per year depending on degree of
infestation and regrowth, treating a fraction of the water body at a time. Herbicide
treatments are applied to the research ponds approximately four times per year. Foliar
broadcast herbicide treatments are applied to the research pond banks approximately
once a year. Herbicides or algaecides under development are applied infrequently to
research ponds. These aquatic applications are conducted in accordance with FIFRA.
Turf research plots are managed with up to four applications per year with herbicides
and fertilizer by broadcast, and treated with fungicides up to seven times per year.
Ornamental research plots are treated approximately once per year with pre -emergent
herbicide and as needed with spot post emergent herbicide.
On September 27, 2017, DEQ issued Findings and Decision and Assessment of Civil
Penalties (the "Civil Penalty Assessment") to SePRO. In the Civil Penalty Assessment,
DEQ alleged that SePRO violated NCGS 143-215(a)(2) by the construction and operation
of a sewer system, treatment works, or disposal system within the State without a
permit and assessed a penalty. Specifically, among other things, DEQ alleged that
SePRO unlawfully disposed of laboratory waste containing pesticides, copper and
solvents to the holding ponds. In response, SePRO took corrective action. Waters from
these holding ponds were discharged to the City of Rocky Mount in accordance with a
Pump and Haul Authorization, and sediment and water from these holding ponds were
stabilized and transported by Republic Waste and landfilled in Aulander, North Carolina.
On October 30, 2017, SePRO filed a Petition for Contested Case Hearing (17 EHR 07350)
with the North Carolina Office of Administrative Hearings disputing several findings of
fact contained in the Civil Penalty Assessment.
On April 16, 2018, SePRO and DEQ executed a settlement agreement (without making
any admissions of liability or violations) resolving all alleged violations.
