DEO - Valley Regional Office 4411 Early Road l P. O. Box 1129 Harrisonburg, VA 22801 i RE: North Anna Power Station - Bearing Cooling Tower Blowdown - VPDES Permit l Application Addendum l
Dear Mr. Pandey:
As recently discussed per telephone, we are proposing to use three chemicals in the bearing cooling tower at North Anna Power Station that were not addressed in our last application for reissuance of the VPDES permit. This information is submitted as an addendum to the original application. We have recently submitted application addenda to the Tidewater Regional Office for new chemicals proposed for use at the Chesapeake Energy Center and Yorktown Power Station. Attached are examples of submittals made to the Tidewater Regional Office.
For years, the bearing cooling tower has been chlorinated on a continuous basis, but has not been blown down. Due to the lack of blowdown, the calcium concentration has increased in the system, resulting in scale buildup. The bearing cooling tower needs to be blown down continuously to reduce this concentration. The estimated flowrate for the blowdown is 150 gpm to 200 gpm. This is an internal discharge that discharges into the circulating water tunnel where it mixes with as much as 2,000,000 gpm of lake water before being discharged into the discharge canal and cooling lagoons.
I Calgon Corporation has recommended the use of a liquid oxidr.. .. system utilizing Calgon H-
/
940 (40% sodium bromide) and sodium hypochlorite (15% active). The chemicals would be fed over a 30-minute period up to four times a day. The feed rates would be 3.5 gallons for Calgon H-940 and 11.3 gallons for sodium hypochlorite during each 30 minute period. Due to varying plant conditions, the recommended feed rate may change. However, at no time would we add these chemicals for more than 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> per day. This treatment method will provide adequate oxidant to control the system and still meet the limitations of our VPDES g'l permit. Attached is the MSD sheet for Calgon 4-940. -
Calgon Corporation has also recommended the use of an amine salt of endothall (Calgon EVAC) to control mollusk infestations in the bearing cooling tower. EVAC would be added to the unit 3 to 4 times a year at the rate of 100-150 pounds per treatmeni to produce a concentration of 1.5 ppm to 3.0 ppm. The treatment is effective in as little as 8 to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
However, the bearing cooling tower would not be blown down for at least 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to provide time for EVAC to naturally decompose. The half-life for this product is 19 to 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Attached is the MSD sheet for Calgor. '.VAC.

Dear Mr. Sauer:
As we discussed earlier today, Energy Center personnel commenced using two chemicals in 1997 that were not addressed in our last application for reissuance of the VPDES permit. We are submitting this information as an addendmn to the original application. l Penetone PL 998, a liquid phosphoric acid cleaner, is used to clean the air preheater l baskets. Approximately 240 gallons of this product are used per year. Wastewater from l cleaning the air preheaters is treated in the metals cleaning waste pond. l ProChemTech 7950, a liquid potassium hydroxide cleaner, is used to restore the activated carbon associated with the reverse osmosis system and t o clean other portions of the reverse osmosis unit. A maximum of 110 gallons is used per year. Depending upon which part of the system is being cleaned, the wastewater is discharged to either the ash pond or the condenser cooling water discharg>: canal.
Attached are the MSD sheets for these two chemicals, a copy of the procedure for cleaning the air preheaters, and a list of the bulk chemicals used at the Energy Center.
If you have any questions, please call me at (804) 273-2992.
Sincerely, Ron Birckhead StaffEngineer i

I September 30,1998 Mr. Mark H. Sauer DEO-Tidewater Regional Office 5636 Southem Boulevard Virginia Beach, Virginia 23462 RE: Chesapeake Energy Center - VPDES Permit application Addendum
Dear Mr. Sauer:
This is to notify you of the proposed use of a new chemical at the Chesapeake Energy Center on a trial basis.
In the past, Energy Center personnel used hydrochteric acid to control scaling on the membranes of the reverse osmosis system. Currently, the water is pre-treated with a water softener. Energy Center personnel are planning on using Hypersperse AF 200 UL, a polymer from Argo Scientific, on a trial basis to control scaling of the membranes. The test period would be for a maximum of two months and the product will be used at the rate of approximately 500 pounds per month. This will allow Energy Center personnel to evaluate the product prior to a planned replacement of the membranes. The discharge would continue to be directed to the condenser cooling water discharge canal. Attached for your information is a copy of the MSD sheet.
We understand that the City of Chesapeake uses this product at its water treatment plant with great success.
If you have any questions or desire additional information, please call me at (804) 273-2992.
Sincerely, Ron Birckhead Staff Engineer I
