Dear Mr. Perry:
In accordance with your application received on November 8, 1993, we are forwarding herewith
Permit No. WQ0006017 dated April 29, 1994, to the Town of Beaufort for the operation of a wastewater
residuals land application program. This permit is to add approximately 216 new acres of land application
sites, listed as CRB 4 fields 1 and 2. Please note that parts of these new fields are restricted or deleted due
to soil conditions. This permit also deletes land application field CRB1-1 (4.9 acres) due to a lack of a
vector attraction reduction method for no till land.
This permit shall be effective from the date of issuance until November 30, 1997, and shall be
subject to the conditions and limitations as specified therein. Please pay particular attention to the
monitoring and reporting requirements contained in this permit. Failure to establish an adequate system for

The COMELIAN_CF, BOUNDARY for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary is
for the disposal system constructed after December 31, 1983 is established at either (1) 250
feet from the waste disposal area, or (2) 50 feet within the property boundary, whichever is
closest to the waste disposal area. An exceedance of Groundwater Quality Standards at or
beyond the Compliance Boundary is subject to immediate remediation action in addition to
the penalty provisions applicable under General Statute 143-215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BQUNDARY is established around the
disposal systems midway between the Compliance Boundary and the perimeter of the
waste disposal area. Any exceedance of standards at the Review Boundary shall require
remediation action on the part of the permittee.
2. Any groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.
3. No land application of waste activities shall be undertaken when the seasonal high water
table is less than three feet below land surface.
1. The Permittee or his designee shall inspect the residuals storage, transport, and application
facilities to prevent malfunctions and deterioration, operator errors and discharges which
may cause or lead to the release of wastes to the environment, a threat to human health, or a
nuisance. The Permittee shall maintain an inspection log or summary including at least the
date and time of inspection, observations made, and any maintenance, repairs, or corrective
actions taken by the Permittee. This log of inspections shall be maintained by the Permittee
for a period of five years from the date of the inspection and shall be made available to the
Division of Environmental Management or other permitting authority, upon request.
2. Any duly authorized officer, employee, or representative of the Division of Environmental
Management may, upon presentation of credentials, enter and inspect any property,
premises or place on or related to the application site or facility at any reasonable time for
the purpose of determining compliance with this permit; may inspect or copy any records
that must be kept under the terms and conditions of this permit; and may obtain samples of
groundwater, surface water, or leachate.

and as per the seasonal period listed above.
4 - Field CRB 4-2 subdivision B (see Attachment B) shalI be deleted from the rest of
field CRB 4-2 and not receive residuals due to the high water table and presence of
poorly drained Rains soils.
5. Surface applications of residuals on pasture or no till sites is disallowed until the Town of
Beaufort has present acceptable vector attraction reduction method(s) to the Division. This
is based on the Town's proposal to incorporated the surface applied residuals per 40 CFR,
Part 503 requirements for vector attraction reduction.
6. Failure to abide by the conditions and limitations contained in this permit may subject the
Permittee to an enforcement action by the Division of Environmental Management in
