operation of a bauxite residuals reuse program (as structural fill) on Alchem, Inc.'s property at 8135 Red Road,
Rockwell, North Carolina using approximately 3000 dry tons per year of residuals from the sources listed in
Condition 11 2, with no discharge of wastes to the surface waters, pursuant to the application received on
October 23, 1998, and in conformity with the project plan, specifications, and other supporting data
subsequently filed and approved by the Department of Environment and Natural Resources and considered a
part of this permit.
This permit shall be effective from the date of issuance until December 31, 2004 and shall be subject
to the following specified conditions and Iimitations-.
I. PERFORMANCE STANDARDS
1. The residuals program shall be effectively maintained and operated as a non -discharge system to
prevent the discharge of any wastes resulting from the operation of this program.
2. This permit shall become voidable in the event of failure of the residuals program to adequately
protect the assigned water quality standards of the surface waters and groundwaters.
The issuance of this permit shall not relieve the Permittee of the responsibility for damages to
surface or groundwaters resulting from the operation of this program.
4. In the event that the bauxite residuals reuse program is not operated satisfactorily, including the
creation of nuisance conditions, the Permittee shall cease the reuse operation take any immediate
corrective actions as may be required by the Division of Water Quality (Division).
Written notification must be submitted to the Mooresville Regional Office, [phone], at least
two weeks prior to any use of residuals within 50 feet of any surface waters.
6. No residual shall be used with 100 feet of a potable water supply well unless a clay or synthetic
liner is placed over and under the residual during installation. It will be the responsibility of

Alchem, Inc. to verify the position and integrity of the liner prior to backfill. Under no
circumstances shall residuals be located within 25 feet of a potable water supply well.
H. OPERATION AND MAINTENANCE REOUIREMENTS
No residuals other than the following are hereby approved for use in accordance with this permit:

and within three feet of a permanent water table.
No residuals shall be used as pipe bedding for sanitary sewer, storm sewer, or potable water lines.
The permittee shall insure that the transportation of the residuals does not cause any adverse
impact, i.e. transport in a leak proof truck for wet material, ensure that trucks are covered for dry
material, or otherwise protected to prevent any adverse impact resulting from operation.
III. MONITORING AND REPORTING REQUIREMENTS
Any monitoring (including groundwater, surface water, residuals, soil, or plant tissue analyses)
deemed necessary by the Division to insure protection of the environment will be established and
an acceptable sampling and reporting schedule shall be followed.
Proper records shall be maintained by the Permittee tracking all utilization activities. These

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 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.
2. Any groundwater qua]ity monitoring, as deemed necessary by the Division, shall be provided.
V. INSPECTIONS
1. The Permittee or his designee shall inspect the residuals storage, transport and fill sites to prevent

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 or other permitting authority,
upon request.

of credentials, enter and inspect any property, premises or place on or related to the treatment 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

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