SUSQUEHANNA STEAM ELECTRIC STATIONUSE OF DEPOSITROL PY5206CCN 741326 FILE R9-8APLE-

Dear Mr. Swerdon:

PPEcL, Inc. is submitting information to the Pennsylvania Department ofEnvironmentalProtection,(PaDEP) for the Susquehanna Steam Electric Station (SES) to update water treatmentinformation previously submitted for NPDES Permit No. PA 0047325. PPkL, Inc. requestsapproval ofDepositrol PY5206, a scale inhibitor, for use in the Emergency Spray Pond. PP8cLbelieves that there willbe no additional impacts to the waters ofthe Commonwealth resulting&om use ofDepositrol PY5206.

Previously the PaDEP approved another scale inhibitor, Powerline PPL 11, however, because ofthe continued drought and warm weather, Powerline PPL 11 is not inhibiting scale in this pond.Depositrol PY5206 has an active ingredient, alkyl epoxy carboxylate (AEC), a non-phosphatecalcium carbonate inhibitor, while Powerline PPL 11 has an active ingredient ofhydroxyethylidene diphosphonic acid (HEDP). A comparison ofbioassay data shows that DepositrolPY5206 is less toxic than Powerline PPL 11.

In response to the requirements of"Permitting Guidance on Conditioned Water Discharges andUse ofChemical Additives, Revised July 24, 1992," PPdtJ. has submitted this request for ggQ)approval for the use ofDepositrol PY5206, a scale inhibitor. Attachment 1, Data for ChemicalAdditive Depositrol PY5206, provides information required in the PaDEP permitting guidancedocument. Attachment 2 is a Material Safety Data Sheet for this product, and Attachment 3 is a

Product Facts Sheet about this product's active ingredient, AEC.

We understand that the PaDEP review process takes up to 60 days; however, ifscale in thisEmergency Spray Pond should impact operation ofSusquehanna SES emergency systems, wewillnotifyyour oKce and request an emergency approval. It is PPRL's understanding that

Depositrol PY5206'can control scaling during extended drought conditions.

Ifyou have any questions please contact Jim Wolfer at the Susquehanna SES, (570) 542-3981 or

ADDITIONANDAFFECTED OUTFALLS

The addition point is the Spray Pond. The Spray Pond outfall discharges into the

Cooling Tower Blowdown line. See attached line,drawing.

THE EXPECTED CONCENTRATION OF PRODUCT ATFINALOUTFALL

The expected concentration ofDepositrol PY5206 in the Emergency Spray Pondwillbe 32 mg/1 as product. The expected concentration ofproduct discharged

'om

the pond through the final outfall, the Cooling Tower Blowdown{Outfall071) as product is between 0.67 tol.14 mg/1. See the response to No. 10

for additional information.

THE PRODUCT. DENSITY FOR LIQUIDS (lb./gal) USED TO CONVERTUSAGE RATE (gpd) TO IN-SYSTEM CONCENTI4LTIONS (mg/l)

The quantity ofproduct used daily is based on the average Spray Pond dischargerate of250 gpm, and a maximum pond concentration of32 mg/l as product.

At 250 gpm, the pond daily blowdown in pounds equals:

250 gpm x 1440 min/day x 8.33 lbs./gal = 3.0E6 lbs./day

At 32ppm, the weight ofproduct discharged per day equals:

32 mg/1 x (3.0E6 lbs./day/1E6 mg/1) = 96lbs./day..

At 96 lbs./day, the daily usage rate in'gallons per day equals:

Wt/gal product = sp gr 1.27 x 8.33 lbs./gal = 10.6 lbs./gal

96 lbs./day/ 10.6 lbs./gal = 9 gallons per day.r

Depositrol PY5206 treatment ofthe Emergency Spray Pond at the SusquehannaSES is needed to effectively control common scales such as calcium carbonate,and also fouling which occur due to iron and other suspended solids. During thepresent severe drought conditions, this chemical willreplace previously approvedHydroxy Ethylidene Diphosphonic Acid (HEDP) another scale inhibitor. Theactive component (AEC) is more stable and has a greater protection range thanHEDP.

CONTINUUM AECAlkaline Cooling Water Treatment

~ Controls deposition and scale with patented AECnon-phosphonate technology

~ Maximizes corrosion protection without heavymetals

~ Minimizes or eliminates acid feed~ Stable in presence of halogens

DESCRIPTION AND USE

Continuum> AEC products are custom designedblends containing alkyl epoxy carboxylate (AEC).AEC, a non-phosphonate calcium carbonate inhibitor,ls the primary ingredient used for patented depositcontrol technology.

These Continuum products control corrosion andscale formation in open recirculating cooling watersystems over the alkaline pH range of 7.8. to 9.0.'Continuum products with AEC are versatile'and havebeen successfully used in a broad range of systemsoperating under varying conditions.ITYPICALAPPLICATIONS

Coritinuum AEC programs are designed for coolingwater systems operating at alkaline pH, typically 7.8or above. This means that acid feed and the costsand concerns associated with it may be reduced oreliminated.

Continuum products with AEC effectively control com-mon scales, such as calcium carbonate, and foulingwhich occur due to iron and other suspended solids.

AEC technology ls a major breakthrough in calciumcarbonate scale control. Figure 1 demonstrates theability of AEC to inhibit calcium carbonate scale com-pared to other conventional inhibitors.

Organic phosphate inhibitors are susceptible tobreakdown or reversion in the presence of chlorine.Figure 2 demonstrates that there is no loss of cal-cium carbonate scale inhibition by AEC in the pres-ence'of chlorine.

Continuum AEC programs'inhibit the corrosion ofmild steel, copper, and copper alloys.

THE BElZDEARBORN ENVIRO-GUARDCOMMITMENTBetzDearborn is committed to the preservation andenhancement of our global environment, improvinghealth and safety, and fostering environmentalawareness. We pledge to provide a Return onEnvironment (ROEG) to our customers, employees,neighbors, and the public by holding ourselvesaccountable to the highest standards of environ-mental responsibility.

Continuum AEC-programs were designed toenhance workplace safety and minimizeimpact onthe environment.

TREATMENTAND FEEDING REQUIREMENTSThe particular combination of active, ingredientsrequired to give the best results depends on the sys-tem metallurgy, temperature, water chemistry, andother system characteristics. Your SetzDearbornsales representative will recommend the most effec-tive treatment for your system.

Dosage - The proper treatment level of ContinuumAEC products depends on the needs of your systemand the product selected. The product should be fedIn accordance with control parameters thatBetzDearborn Water Management establishes foryour particular application. For consistent protection,continuous feed is recommended.

Feedpoint - Continuum AEC should be fed to a pointin the cooling system where it rapidly mixes with thebulk cooling water.

Dilution - For best results, Continuum AEC productsshould be fed neat. Dilutions, if necessary, can onlybe made with low hardness water.

Feed Equipment - Tanks, pumps, piping, and.valves should be made of stainless steel, polyethyl-ene, or PVC. Equipment recommendations for spe-cific blends are available upon request.ENVIRONMENTALINFORMATION

Aquatic toxicology data and regulatory information isavailable for each Continuum AEC program. Contactyour BetzDearborn Water'Management Group salesrepresentative for detailed information about a spe-cific product.

PACKAGING INFORMATIONContinuum AEC products are liquid blends, availablein a wide variety of customized containers and deliv-ery methods. Contact your BetzDearbom sales rep-resentative for details.

SAFETY PRECAUTIONS-Material Safety Data Sheets containing detailedinformation about products in this series are avail-able upon request.
