RE: SURRY POWER STATION - VA #0004090 - CHEMICAL ADDITION CHANGE

Dear Ms. Cook:

This is to request approval from your agency for a proposed change in chemical addition for pH control in the feedwater system at Surry Power Station. As you may be aware, maintaining specific levels. of pH in steam generation systems is essential in the control of corrosion in these systems. Currently, ammonia is the chemical additive employed for this pH adjustment * . The proposed change will be to substitute another product, ethanolamine (Calgon Pre-Teet 7000), for ammonia.

In the feedwater systems, the target concentration of ethanolamine will . be in the range of 1. O - 3. O ppm. Due to distribution properties under system temperature and pressure conditions, concentration in the blowdown from the steam _generators, to*

internal outfalls 181 and 191,.may increase to a maximum of 10 ppm.

At its maximum concentration in blowdown, and at the maximum blowdown rate of 70 gpm from each of six steam generators, the highest rate of discharge of ethanolamine, and its decomposition products, to the discharge canal would be 50. 4 7 pourids per day.

This is a theoretical worst case situation that would not be expected to actually occur since the steam generator blowdown is normally recovered and reprocessed for use within the steam generating system.

Ethanol amine decomposes to short chain . organic acids (acetic,*

formic, glycolic), ammonia, and other organic amines. Even without allowance for any decrease in concentration through decomposition, the concentration of ethanolamine at the outfall 001 discharge, under worst case conditions (<0.003 ppm), would be lower than the aquatic toxicity levels provided by the supplier. The supplier's data and the product Material Safety Data Sheet are attached.
