I. PERFORMANCE STANDARDS

which will protect the assigned water quality standards of the surface waters and ground
waters.
2. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those
actions that may be required by the Division of Water Quality (Division), such as the
construction of additional or replacement treatment or disposal facilities.

4. Any residuals generated from these treatment facilities must be disposed in accordance
with General Statute 143-215.1 and in a manner approved by the Division.
5. Diversion or bypassing of the untreated groundwater from the treatment facilities is
prohibited.
H. OPERATION AND MAINTENANCE REQUIREMENTS

or characteristic, such as the dumping of the contents of a basin or tank, the known
passage of a slug of hazardous substance through the facility, or any other unusual
circumstances;
b. Any process unit failure, due to known or unknown reasons, that renders the
groundwater treatment and disposal system incapable of adequate treatment and
disposal, such as mechanical or electrical failures of pumps, aerators, compressors,
etc.;
c. Any failure of a pumping station, sewer line, or treatment facility resulting in a by-
pass directly to receiving waters without treatment of all or any portion of the influent
to such station or facility; or

and disposal system is not in compliance with any specified permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within five (5) days following first knowledge of the occurrence. This report must
outline the actions taken or proposed to be taken to ensure that the problem does not recur.
IV. GROUNDWATER REQUIREMENTS
The influent and effluent from the treatment system shall be sampled monthly using EPA

action in addition to the penalty provisions applicable under General Statute 143-

In accordance with 15A NCAC 2L, a REVIEW BOUNDARY 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.
4. All components of the groundwater recovery, treatment, and disposal system shall be
properly weather -proofed to prevent freezing and failure of the system.

1. Adequate inspection, maintenance and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.

2. The Permittee or his designee shall inspect the groundwater recovery and treatment
facilities to prevent malfunctions and deterioration, operator errors and discharges which

all statutes, rules, regulations, or ordinances which may be imposed by other government
