Dear sir,

In support of our request submitted with Ref. 9, UNC encloses updated pages of the environmental evaluation which was submitted with Ref.

t 1.

What are the expected chemical and radiological emissions (gaseous and l

liquid)?

t Wash / shower water, and Chem imb liquids commistent with current i

lab operations go to the existing radwaste system in the B-south basement for treatment and disposal.

Additional chemical liquids j

2.

generated are identified ass i

I-ity film fizer and developer solutions - these solutions aro ggi radiometrically contaminated and are collected, I

pr ressed for silver rooovery, and disposed of on a batch basas by a licensed hasardous waste hauler.

Similar processing and disposal is underway from our ourrently

}

licensed facilities and this represents an addition to ourrent established procedures and practice.

I-ray film rinse we.ter - this effluent is nei

)

radiometrically contaminated and will be discharged as l

process water to the sanitary sewage system under appropriate state Permit.

This represents an addition to ourrent established procedures and practice.

Detergent Wash - This solution is att radiometrically contaminated and is generated from the washing of non-fuel metal components.

The detergent is batch collected and 5

disposed of as basardous waste via a licensed hauler.

This represents an addition to current established procedures and t

practice.

Detergent Rinse Water - This effluent is generated from i

rinsing non-fuel components previously washed and will be discharged as process water to the sanitary sewage system under appropriate state Permit.

This represents an addition to current established procedures and practice.

Used hydraulio and vacuum pump oils to approved off site disposal.

The gaseous emissions are air or argon from any of the stacks listed in Table 1, with occasional residual amounts of organic vapors and radionotive materials which have not been removed by the EEPA filters or scrubbers.

The chemical solvents methylene chloride and octane are used in the production process.

Extensive engineered controls and monitored solvent recovery units have been established to create a closed loop solvent recycling system.

These will ensure that only minimal quantities are released, and that they are well within requirements of the ct. Department of Environmental Protection.

Additional trace quantities of isopropyl alcohol resulting from cleaning / wiping of work surfaces and parts will be intermittently exhausted.

Chemistry lab analytioal operations, necessary to confirm product

[

quality, saa also result in the ooossional release of small amounts of soldio fumes.

These stacks are EEPA filtered or scrubbed prior to discharge.

i 2.

Provide an evaluation of the potential environmental impacts due to i

the emissions.

i As stated in Ref. 1, the new stacks are associated with similar i

(

operations to those of 3-South, and the B-south operations have dooreased substantially over the last several years.

Therefore there is no change in the environmental impacts from Ref. (5).

j 3.

Provide a description of the release points for gaseous emissions (i.e., stack dimensions, vents) and desoribe the protective measures used to prevent releases to the environment (i.e., use of filters, scrubbers).

Table 1 and Figure 4.4.2.2 provide a description of the release points for gaseous emissions from L-Building.

All exhausts will be EEPA filtered or scrubbed as described in Section 4.4.2.3, Part I of the current license.

I 4.

Describe the monitoring provided on the effluent streams.

i As stated in Ref. 4, the monitoring provided on the affluent streams is per Ref. (6) Tsble II, a portion of which is given below.

t 5.

Discuss any potential accident scenarios that would be different from those for existing operations.

t As stated in Ref. 8, the potential accidents are the same or less than those previously noted in Ref. (5) and.Ref. (7) because less hasardous octane has replaced hazano in all applications.

6.

Describe any processing of the liquid waste stream.

As stated in Ref.

8, the processing of the liquid waste stream is as described in the present license, section 4.4.3, Part I and as evaluated in Ref. (5).

7.

Provide an unclassified site plan showing building locations.

Figure E 740913-150 submitted with Ref. 8 applies.
