DIVISION OF WATER QUALITY
GROUNDWATER SECTION
January 5, 1998
MEMORANDUM
To: Kim Colson
Water Quality Section
Through:, Bob Cheek f.1z, c
From: Brian Wootton All
Subject: Zemex Corporation
Bear Creek Plant
Wastewater Recycle System
Mitchell County
Permit No. WQ0003699/GW98172
Ron Palumbo: SERG Review Engineer
The Groundwater Section has reviewed the subject permit renewal/modification request for
the continued operation of the recycle system and modification to add 2 ponds with a storage capacity
of 1,195,154 gallons each. The plant process is to recover mica, sand and clay materials. The sand
and mica are collected at the plant and the clay is collected at a series of existing ponds (basins). To
increase production at this facility, the water usage will increase from 18,000 GPD to a maximum
of 900,000 GPD . Once the new ponds are in operation, the existing ponds will not be used for the
recirculation system. The new ponds will have a clay soil liner two (2) feet thick and the base of the
ponds will be established about four (4) feet above the groundwater table.
Based upon the Groundwater Section's review of the subject permit application and
supporting documentation, the Groundwater Section makes the following recommendations:
* 1. The lagoons shall have a liner of natural material at least two feet in thickness (as specified
by the design engineer), compacted to a 95% proctor standard dry density and installed and
compacted in layers no thicker than six inches, with a hydraulic conductivity of no greater
than 1 x 10-6 cm/sec. Following installation and inspection of the lagoon liner, and prior to
waste disposal operations, verification of the liner's compliance with hydraulic conductivity
and thickness specifications must be provided to the Division of Water Quality, Groundwater
Section, by the project engineer.

2. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in
15ANCAC 2L,, Groundwater Classifications and Standards. The Compliance Boundary for
the disposal system individually permitted after December 31, 1983 is established at either
(1) 250 feet from the waste disposal area, or (2) within 50 feet of 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 BOUNDARY is jestablished _around the
disposal system 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.
5. Any groundwater quality monitoring, as deemed necessary by the Division, shall be provided.
*Denotes different language than the shell document.

A004 DEFINITIONS
The following definitions shag apply throughout this Subchapter.
(1) Activated Carbon Beds. A physlcallcfemical method for reducing soluble organic material from wastewater effluent; The column -type beds used in this
method will have a lbw rate varying from two to eight gallons per minute per square loot and may be either upflow or downfiow carbon beds. Carbon may or
may not be regenerated on the wastewater treatment plant she; -
(2) Aerated Lagoons. A basin in which all solids are maintained In suspension and by which biological oxidation or organic matter Is reduced through artificially
accelerated transfer of oxygen on a flow -through basis;
(3) Aeration. A process of bringing about Intimate contact between air or high purity oxygen In a liquid by spraying, agitation or dffuslon;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 16 hours.
(4) Agriculturally managed she. Any site on which a crop is produced, managed, and harvested (Crop Includes grasses, grails, trees, ate-);
(5) Air Stripping. A process by which the ammonium Ion Is first converted to dissolved ammonia (pH adjustment) with the ammonia then released to the
atmosphere by physical means; or other similar processes which remove petroleum products such as ber¢ene, toluene, and xylene;
(6) Carbon Regeneration The regeneration of exhausted carbon by the use of a furnace to provide extremely high temperatures which volatilize and oxidize the
absorbed knpuritles;
°'J7) Carbonaceous Stage. A stage of wastewater treatment designed to achieve 'secondary' effluent Ilmhs;
' (8) Centrifuge. A mechanical device In which centrifugal force is used to separate solids from liquids or to separate liquids of dMerenl densclas;
(9) Chemlal Addition Systems- The addhion of chemical(s) to wastewater at an application point for purposes of Improving solids removal, pH adjustment,
alkalinity control, etc.; the capability to experiment with different chemicals and diferent application points to actlleve a specific result will be considered one
system; the capability to add chemicai(s) to dual units will be rated as one system; capability to add a chemlcal at•a different application points for different
purposes will result In the systems being rated as separate systems;
(10) Chemical Sludge Conditloning. The addition of a chemical compound such as lime, ferric chloride, or a polymer to wet sludge to coalesce the mass prior to
its application to a dewatering device;
(11) Closed Cycle Systems: Use of holding ponds or holding tanks for containment of wastewater containing inorganic, non -toxic materials from sand, gravel.
cashed stores or other similar operations. Such systems shag carry a maximum of two points regardless o1 pumping facilhies or any other appurtenances;
(12) CombinedRemoval of Carbonaceous SOD and Nitrogenous Removal by Nitrification- A single stage system required to achieve permit effluent limits on BOD
and ammonia nhrr.,en whNn the same biolooical reactor_
