Dear Mr. Mulligan:
September 23, 1992
ACCEPTANCE OF KENTEC TREATED GROUNDWATER
The E. I. Du Pont Kinston Plant, N.C. NPDES Permit No.
0003760 agrees to accept the treated groundwater generated by the
remediation project at the E. I. Du Pont Kentec site.
The oxygen demand of the treated groundwater is below
detectable limits; therefore, the only effect will be hydraulic load. The
maximum volume of 7200 gpd that could be generated at Kentec would
not be of significant impact to the Kinston Plant wastewater system.
The system normally discharges 2.5 mgd versus a 3.6 mgd permitted
daily average.
If there are questions regarding this matter, please contact
Jan A. Kneib, Environmental Coordinator at (919) 522-6294.
