PROJECT NOTES
Summary
• This is an application for a new discharge from a groundwater-supplied-water
treatment plant (WTP), which will discharge backwash water from a green sand
filter. The reason for requesting the discharge is to eliminate the backwash water
from the onsite septic system, which is undergoing upgrades to better handle
domestic wastewater from 770 students (max). The backwash water will discharge
three times per week with approx. 900 gal/event.
• The proposed discharge is to an unnamed trib to Hyco Creek, which flows into
Hyco Lake. Hyco Creek is not 303(d) listed, and the Roanoke Basin Plan (1996)
lists no specific management strategies for this waterbody.
Permit Development
• Permit limits developed in accordance with September 1992 Water Treatment
Plant Discharge Policy. Limits imposed for TSS, settleable solids, and turbidity.
Since the discharge is to a dry ditch, apply turbidity limit of 50 NTU at the effluent.
Facility plans to backwash filters with chlorinated water, therefore TRC monitoring
applies. Alum flocculation is not utilized, so no aluminum monitoring required.
Since design flow is <5,000 gpd, quarterly sampling is appropriate for all
parameters. Applicant is not proposing any type of backwash treatment system at
this point.
• USGS provided flow data for Hyco Creek, and identified it as a zero-flow stream
(s7Q 10 = 0). State regulations prohibit discharge of oxygen consuming waste to
zero flow streams; however, the proposed discharge of filter backwash contains no
oxygen-consuming waste.
Engineering Alternatives Analysis (EAA).
• The applicant submitted the required EAA. Generally alternatives are limited for
filter backwash systems. Connection to the Yanceyville WWTP is not feasible,
given the distance to the sewer system (approx. 8 miles). The DEH onsite
wastewater permit was issued contingent upon elimination of the filter backwash
from the new subsurface system; therefore, onsite treatment is also infeasible.
Soils in the area are not amenable to water infiltration. Both NPDES and the
WSRO concur with the request for direct discharge of filter backwash.
Region Data.
• WSRO recommends permit issuance.

It has been decided that a toxicity condition will not be included in the permit, as
recomended in memora__dum dated 9/18/92 (copy attached), until further information is
collected and reviewed. Let me reiterate that this is an interim solution. Once we have
completed a survey of water plants and further review of the chemical and toxicological
effects of these types of discharges, we will be finalizing the permit requirements. If you
have any question, please contact me. -

PART IV - EVALUATION AND RECOMMENDATIONS
The Caswell County School system proposes to discharge well backwash water from the
existing potable water system at South Elementary School. Currently, the well backwash
wastewater is routed to a recently repaired ground absorption system treating the domestic
wastewater from the school. The DEH On-Site Wastewater Sections repair permit was issued
contingent upon the elimination of the well backwash from the new subsurface system.
WSRO recommends issuance of the proposed NPDES permit for the non-oxygen
demanding well backwash water.
