Claibome Enrichment Center LWDPS and NPDES Permits to Discharge Wastewater Permit Numbers: LA 0092196/WP 4154 File: 6046-2001.M

Dear Ms. Lejeune:

Thank you for the input you provided concerning the referenced permit applications in your September 30,1992, letter. Following are the responses you requested to the four questions contained in your letter:

Qucatiolt1: There is some question as to the source of the regulatory limits listed in Table 4.4-2 in Attachment 8 of the LWDPS permit application submitted on July 2,1992. What is the rationale and specific citation for the limits as listed?

Responsc: The values for pH, chlorides, and sulfates were taken from LADEQ regulations at 33:IX.ll23, Table 08, Code Number 080601. _ The value for oil and grease was taken from LADEQ regulations at 33:IX.709. The values for arsenic and chromium wers taken from i ADEQ regulations at 33:IX.1113 Table 1. ne value for copper was taken from EPA's (cality Criteria for Water,1976 (commonly known as the " Red Book"). The values for cadmium, lead, nickel, silver, iron, selenium, and zine are MCL's or water quality criteria taken from the 'ntegrated Risk Information System (IRIS) data base published by the USEPA.

Question _2: Uncontammated stormwater runoff from the facility was overlooked in the application as a scurce requiring monitoring and sampling. Please complete Secti3n II of the SCC-2 application addressing this runoff from Outfall 002 to Bluegill Pond.

d Ms. Cheryl Lejeune October 30,1992 Page 2 Response: LES' intention was to permit the discharge of stormwater via the EPA's General Stormwater Permit regulations. This intent was indicated in the Louisiana Wastewater Permit application and in the NPDES permit application on EPA Form 1. At the request of LADEQ and with the concurrence of EPA, LES has modified the permit application to permit this point source discharge of stormwater from the hold-up basin to Bluegill Pond as Outfall OCG in the NPDES and Louisiana Wastewater permits. As requested by LADEQ,Section II of DEQ Form SCC-2 has been completed for this discharge and is attached. Also attached is the updated water balance (drawings 6046-06 2001.064001 and 6046-06-2001.06-0002) including information for this outfall.

Question.3: Does the possibility of mdioactive contamination of the stormwater that exits Outfall 002 exist? Please give a detailed explandtion of the procedure for transportation and storage of any radioactive material at the site.

Response: There will not exist a possibility of radioactively contaminated process wastewater being discharged at Outfall 002 (stormwater point source discharge to Bluegill Pond). There exists the possibility of radioactive contamination in this discharge from two sources: the settling of minute quantities of airborne radiation within the plant yard area, and accidental releases. Botn the emission of airt>ome radioactive contamination and facility safeguards against accidental releases are regulated by the US Nuclear Regulatory Commission. LES has proposed to the NRC in the Claiborne Enrichment Center's Environmental Report to monitor the discharge of stormwater from the hold-up basin to Bluegill Pond for the presence of radioactive contamination. As requested in your letter, the enclosed Claibon.e Enrichment Center's Safety Analysis Report (SAR) Section 4.3.3 with SAR Tables 4.3-16 and 4.3-17 provides information concerning the transportation and storage of radioactive material at the site.

Question 4: During the meeting, there was some confusion as to the origin and quandry of carbon tetrachloride actually discharged through Outfall 001. Please verify the analytical numbers for carbon tetrachloride as presented in Attachment 5 of the application.

Response: The source of carbon tetrachloride is analysis conducted in the facility laboratory.

At the request of LADEQ, the applicant has reviewed the laboratory requirements to determine if the quantity of carbon tetrachloride discharged can be reduced. Administrative procedures can be implemented which ~ill reduce the discharge concentration to less than 0.001 ug/1. This concentration is considerably lower than the value of 18.0 ug/l which LADEQ stated as being acceptable during the Septemt,er 22,1992, me-ting. The applicant has also determined that laboratory administrative procedures can be implemented to reduce the discharge concentration of carbon disulfide to less than 0.001 gg/1. This reduction in discharge concentration of carbon tetrachloride and carbon disulfide has been reflected in the attached table summarizing laboratory chemical use and discharge. This table was included in the permit application as Attachment 5 and is titled " CEC 12b Chemicals in Waste Streams."

Ms. Cheryl Lejeune October 30.1992 Page 3 These responses should address all of the concerns relative to the subject surface water discharge permit applications that were expressed in the September 22,1992, meeting and your subsequent letter of September 30,1992. By copy of this letter and attachments, this information is also provided to Mr. Fred Humpke of EPA Region V1 for inclusion in the NPDES permit application.

If you would like further information, please call me at (704) 373-8466.

Sincerely,

0h $.

'4. 3. 3 MATERIALS HANDLING AND E'2 RAGE Uranium in the form of uranium hexafluoride, UF6, is handled during processi.ng, storage and transportation.

During processing UF6 is handled in the solid, liquid and gaseous phase.

During storage and transport, UF6 is handled only in the solid phase and-then only at a temperature below 129 F (the temperature at which the sublimation vapor pressure is atmospheric).

4 4.3.3.1 Process UF6 Handling Liquid iolid and gaseous UF6 is handled in international cylindess nich are designed, teJted, inspected and maintained for this purpose.

According to NRC recommendation (NUREG 1198) secondary centainment in the form of specially designed autoclaves is provided whenever UF6 is in the liquid phase or is above atmospheric pressure.

Cylinder' are transported only when UF6 is in the solid state and theq only at a temperature below 129 F.

UF6 is handled at subatmospheric pressures throughout the remainder of the process systems.

Leakage in any of these components results in an inflow of air.

InstrumentatAon, controls and alarms are provided to sense pressare fluctuations and to place the systems into a safe state prior to re.mching pressures where the release of UF6 is possible.

All samples are taken in systems specially designed for this purpose.

Lines are electrically trace heated and components are enclosed in insulated and heated compartments where UF6 desublimation is possible.

Details of UF6 handling in each of the process systens are given in Section 6.3, Enrichment and Other Processing Systems.

4.3.3.2 UF6 Receiving and Storace The functions of th. Receiving and Storage System are to receive, inspect, weigh and store cylinders of UF6 sent to the plant for enrichment.

The UF6 is transported only when it's in the solid state and at temperatures below 129 F.

The design requirements of the Receiving and Storage System are surunarized in Table 4.3-15.

The system consists of an unloading dock, crane, accountability scale, (located in the Cylinder Receipt and Dispatch Building),

mobile cylinder transporters and a cylinder storage area.

The UF6 feed is delivered to the plant by truck in 48 inch diameter cylinders.

Cylinders are unloaded by crane,. unpacked, inspected for integrity, weighed and transported to the storage area by a mobile transporter, i

4.3.3.3 UF5 Transporta* ion i

i

.he international UF6 cylinders are moved within the UF6 building L

by a rail transporter.

They are moved between buildings and l

1

sterage areas _by a mobile-transporter.

UF6 is transported only who-it is in the solid state and at temperatures below 129 F.

NRC/00T approved specifications-for most of the types of containers handled are given in Table 4.3-16.

4.3.3.3.1-Rail Transporter A crane on the UF6 building receiving / shipping dock loads UF6 cylinders onto the rail transporter which travels the length of the building on rails.

The rail transporter is then positioned to load and unload cylinders into the autoclaves and cylinder stations which line the track.

4.3.3.3.2 Mobile Cylinder Transporter The mobile cylinder transporters move the international UF6 cylinders among the Receipt and Dispatch Building, the Separations Building and the feed) product and tails storage areas.

4.3.3.4 Tails scorace The Tails Storage System functions to store _ tails cylinders.

The design requirements of the Tails Storage System are summarized in Table 4.3-17.

The Tails Storage System consists of an outdoor storage area reinforced chocks on which the cylinders rest and a mobile cylinder transporter.

Cylinders are transferred to the UF6 Building storage area from the tails take-off cylinder stations and from there by mobile transporter to the storage area where they are placed on chocks.

4.3.3.5 Licuid Waste systems A Liquid Waste Disposal System (LWD) collects, stores, and processes potentially contaminated aqueous wastes from the Separations Building.

Licuid wastes handled by the system include:

a.

Contaminated laundry waste water b.

Decontamination. solutions c.

Laboratory wastes d.

Floor, equipment and laboratory drains.

These liquid wastes are collected, processed by' filtration and evaporation,_ sampled and analyzed.

Liquid waste that meets release criteria is pumped to a Sewage Treatment System for processing of organic materials.

Liquid waste that does not meet release criteria is reprocessed.

Treatment is described in Section 7.1.2, Liquid Waste Treatment.

1 s

e e

s m

Further description of liquid effluents, their treatment and disposal and release criteria are given in Section 4.4.2.4, Liquid Effluents.

The design requirements for the Liquid Waste Disposal System are summarized in Table 4.3-18.

Small quantities of uranium compounds and hydrocarbon oil may be contained in the Fomblin oil used in the UF6 vacuum pumping systems.

The UF6 degrades in the oil or reacts with hydrocarbons forming UF4 or UO2F2.

These crystalline compounds gradually thicken the oil until pump operation is impaired.

The quantity of contaminated oil is expected to be about 80 gallons per year.

The dissolved uranium compounds are removed from the oil by

^ *y~";

precipitation with unhydrous sodium carbonate, filtration and centrifugation.

Unreacted hydrocarbons are removed by heating the Fomblin oil and venting hydrocarbon vapors to the Gaseous Effluent Vent System.

Recovered gomblin oil which contains 50

.gk ppm or less of uranium compounds by volume or 30 ppm or less by US g;.

weight is reused; otherwise it is reprocessed until it meets this 43 specification, y.

4.3.3.6 Gaseous Effluent Systems The Gaseous Effluent Vent System provides for the collection and treatment of potentially contaminated gases.

The Heating Ventilation and Air Conditioning (HVAC) Vent provides for the collection and discharge of normally uncontaminated plant air.

The Technical Services Area HVAC System serves the uncontaminated areas (workshops, laboratories, access corridors and storage areas) and potentially contaminated areas (decontaminatien facilitieu, locker rooms, contaminated workshops, and miscellaneous waste storage and support areas).

Some of these areas contain fume hoods which exhaust to the Gaseous Effluent Vent System.

The design requirements for the Gaseous Effluent Vent System and the HVAC Vent are given in Table 4.3-19.

The Gaseous Effluent Vent System is a central system serving the entire plant.

It provides for the collection of potentially contaminated gases from vacuum pumps, desublimers, autoclaves and other piping and equipment potentially exposed to UF6 and/or HF.

These gases pass through filters and chemical adscrption traps prior to release.

The system is further described in Section 5.3.7, and in Fi,ure 6.3-9, Process Flow Diagram, Gaseous The HVAC system is described in detail in Effluent Vent S' "m.

Section 6.4.1.

Lding Ventilation.

4.3.3.7 solid Maste Disposal System Solid ef fluents come from a number of sources and are segregated into those contaminated with chemicals and/or uranium and those which are uncontaminated.

a

.o Combustible contaminated solid wastes include items used for decontamination such as cleaning cloths, tissues, gloves, laboratory clothing, filters and swabs.

These wastes are stored in collection containers in the Radioactive Waste Storage Area.

At times the waste may be compacted on-site prior to-shipping for disposal in a low-level radioactive waste disposal facility.

Incombustible solid wastes include mainly scrap metal components and parts which cannot be completely decontaminated.

The quantity of waste per year will be small because of the low failure rates of plant components.

Contamination will be low due to the use of UF6 compatible materials and vacuum tight design of equipment components.

These wastes are packaged and stored in the Radioactive Waste Storage Area or in a special container awaiting shipment for off-site treatment or disposal.

Activated carbon, alumina, sodium fluoride, air pre filters.and HEPA filters are sorted in collecqion containers in the Radioactive Waste Storage Area.

At times the waste may %e first compacted on-site prior to shipping for disposal in a 10. level radioactive waste disposal facility.

The Maximum Permissible Concentration (MPC) of uranium in solid wastes is 350 grams per container or 350 grams per square foot.

The procedures for solid waste handling and an estimate of annual quantities are further described in Section 7.1.3, Solid Waste Treatment and in Section 6.4.16, Solid Waste Disposal System, 4.3.3.8 Decontamination and Disposal of Waste for Decommissioning A decommissioning plan which addresses the disposition of the LES plant at the end of its operating life will be developed and submitted about five years prior to the end of plant life.

This plan includes the safe dismantling, decontamination and salvage or disposal of equipment.

Provisions to implement the plan are incorporated in the plant design.

The plant will be dismantled in a manner which assures the safety of the public and plant personnel.

Material and equipment slated for disposal will be dismantled, decontaminated and packaged in a.anner which complies with applicable federal,. state and local requirements.

Decommissioning is described in detail in Section 11.8, Decommissioning.
