Dear Mrs. Harrison:

This letter represents a noneccpliance rep. opt as required by Part II, Paragraph A.2 of the above referenced Fer=it.

On Tuesday, June 10, 1980, routine sa=pling of the sa=ple

, point 013, cocling t ower blevdcun , resulted in a pH deter-

=ination of 9.10 s.u. pH li=its are 6.0 - 9.0 s.u. Investi-gation reveals the acid feed pu=;s which regulate pH in the tower were cut of service with =echanical problems. Acid was =anually added to the tower to bring the pH back within specification while the pu=ps vere being repaired. Cne of the pu=ps was put tack in servi:e on June 11, and the pH vas

5.60 s.u. The re aining pu=p is now undergoing repair and vill be returned to its ner=al st andby status.

On Thursday, June 12, routine sa=pling of sa=ple point 002, the sanitary sewage effluent, resulted in a pH determination

,- of k.3 s.u. Permit limits are 6.0 - 9.0 s.u.

I The sevage plant is still experiencing the troubles described in our letter o f 16 June 19c0. It has been out of co=pliance since that ti=e. We have =cnitored the sewage plant che=istry and o p e r at ion daily and made efforts to restore it's operation to ec=pliance. We vasted sludge until the volu=e was about 305, then raised the pH in the aeration basin frc= L.5 up to 7.5; and then a solution of desirable bacteria was added to the

, ae- tion basin.

d CL-1119 Mrs. Adlene Harrison June 20, 1960 These actions failed to restore the plant by June 15 and the plant was pu= ped out for disposal by a licensed disposal ser-vice.

As was detailed in our 16 June letter, ve suspect that the microfilming process chemicals, floor vaxes and/or vax strip- .

pers were toxic to the sludge bacteria in the treatment plant.

After all of the above actions failed to restore the treatment plant to normality, it was pumped out and allowed to refill.

We vill continue =onitoring the plant che=istry and operation vith the expectancy that it should stabilize in two to three weeks and begin producing a high quality compliance effluent a6ain.

Dear Mrs. Harrison:

This letter represents a noncompliance report as recuired by Part II, Paragraph A.2 of the above-referenced Permit.

On Thursday, May 29 and June 5, 1980, routine testing of sample point 002 resulted in a pH determination of 5.S and 5.3 s.u. respectively.

Permit limits are 6.0 - 9.0 s.u.

Wastewater coming into the plant is within specification i. e., pH 7.0.

This indicates that some internal reaction is occurring resulting in a lowering of the effluent pH.

Investigation of this violation indicates the probable cause as a substance other than normal domestic waste passing through the treatment l

plant. The plant's chemistry staff has reported chemical in:crferences in scme of the required test procedures. These include dissolved oxygen, chlorine and BOD5 . The amount of interference is nct constan indicating a transient nature for this interfering agent. The chemistry staff has demenstrated these interferences on appropriate dilutions of floor waxes and strippers and microfilming process chemicals. The microfilming i chemical is the strongly suspected foreign agent causi.g the variances.

These microfilming chemicals are now being collected and not allowed to

enter the treatment plant. Performance of the treatment plant is being l

Dear :

i This letter repr-sents a ncncenpliance report as required b:.

Part !!, Paragraph A.2 of the above referenced _;ermits.

On *ednesday April 23, 1930, it was disccvered that s e n. e ' :v _

, pH va*.e.- vas being discharged frem the f.'n i t One eccling tater discharge flu =e at Arkansas :iuelear One. The pH cf the va* er i was L.C. *l e suspect the inadvertent release e=ansted frcm the 4.' n i t Tvc lov-volume vaste system, specifically the re-generative vaste systen. The release occurred during r. trann-fer operation fron one holding tank te c r o t '. e r . Investira-

• ien has revealed tnat the valve.to the discharge flune vna closed during the transfer operstion. It is surcised that the valve must have failed internally and vas alleving un-

treated vas*.evater to escape the confines of the neutrali-cation syster. The discharge was stopped as soon as it was detected b", isclating *he :uspected fault.* valve. The valve i vill.'ce repicced or repaired if it is fcund tc be faulty.

• CL-1CSL Mrs. Adlene !! a rri s on May 5,1980 SIS. Permit li=its are 1.0 =g/l =axi=un for both parameters.

This unit has been out of service for the past sixteen =onths and we feel sure that the high readings are attributable to that fact. Since this s a=pl e is only available during start-up, no follow-on sampling has been done. Boiler blovdovn is directed to the evaporator as soon as the unit has a few hun-dred pounds of pressure. This action in effect, removes any .

concern about this Strean since it is nc icnger discharged te the environment.

Cn Thursday April 2L, 1980, routine sa=pling of sa=ple point C01, the treated sanitary sewage effluent at our Hot Springs facility revealed a fecal eclifor= reading of hTO per 100

=1 sa=ple. Permit li=its are 200 average and LOC =axi=u= per 100 =1. Investigation and fc11ov-up sa=pling on April 28, revealed a low chlorine dosage rate and an incorrect line up of the sludge return syste=. Both of these deficiencies were corrected and a sa=ple taken later that day showed all para-

=eters back in co=plisnee.
