3.0 DESIGN FEATURES AND OPERATING PRACTICES Obhective This section contains a description of design features and operating practices which, if changed, might have a significant environmental impact.
I Specification -
If operating practices or design features are planned which deviate from those described in the bases below, an analysis of their potential environmental impact will be made and a course of action taken to alleviate potential adverse impacts. In addition, if the ecology of the river significantly changes at a future date as, for example, by major changes in water chemistry or reintroduction of shad, an analysis
- of expected impacts and a course of' action to mini =ize the impacts will be provided.
Bases 3.1 Operation of Mechanical Draft Cooling Tower Natural draft cooling towers are utilized to cool the large heat load of the condenser. The mechanical draf t cooling tower cools a mixture r: of service cooling water and a small amount of natural draft cooling tower blowdown, which represents a =uch reduced heat load. The ef fluent b -
from the mechanical draf t cooling tower discharges to the river.
For normal operation, one pump will be operated with up to three f ans to affect maximum cooling without intentionally discharging below river ambient. The tower will be operated manually by the operator f rom the control room to affect maximum cooling without intentionally discharging below river ambient .
As an operator aid, the MDCT cc. be operated in the automatic mode which shifts fans to half speed, reduces the number of fans operating and shifts fans operation from cell to cell. The automatic mode is used to help prevent icing of the FDCT while maintaining discharge temperature as close as possible to river water inlet temperature. The automatic
, control system, however, does not assure compliance with environmental Technical Specifications. The operator will take manual control when necessary to prevent icing or to impros- cooling tower operation with regard to discharge temperature. During suntained cold periods, the discharge will average 3 t' above river ambient. Ilowever, since the tower perfor=ance is a function of air wet bulb temperature which can increase much more rapidly than the river temperatu;c, the tower's per-formance can become ineffective. An example would be a sudden warm day whLle the river is still f rozen. At such time the tower is shut down since its operation would result in increasing the discharge temperature. During such periodn, the discharge temperature is
(
g app cximately 10 F above river ambient.
For cooldown operation two pumps are operated to pump over the mechanical draft cooling- tower fill. If the tower is in the automatic mode of operation, it is shifted to manual operation to achieve maximum
..d. ,
cooling at the beginning of cooldown. *With average winter weather
, 'r' . conditions, dae tower discharge is approximately 12*F above river
(~ ambient at the beginning of cooldown and reduces to approximately 3 F some 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> later. Near the end of cooldown the tower may be

3.2 Chemical Usage This section describes the chemicals used in the plant which are discharged t.o the environment. The equipment in which the chemicals .
are used along the quantities per batch or rate of continuous discharge -
and expected' discharge f req 6ency are included.- - .
?.2.1 Water Treatment The clarifier continually receives approximately 0.05 lb. of 'acionic
- polyelectrolyte and 0.6 lb. of anionic clay per 1000 gallons of water treated to remove suspended solids from the river water. Assuming an average flow of 100 gpm. through the clarifier, sludge containing approximately 60 lb. of clay and 5 lb. of polyelectrolyte plus a highly variable amount of suspended solids removed f rom the river water is blown down from the clarifier each day. The sludge is processed in diatomaceous earth pressure filters and the filtrate is released to the plant river water discharge. The solids couponent is pressed into dewatered blocks. Their disposal is described under solid waters, r A cation - anion string in the cycle =akeup demineralizer system uses
\- 2260 lb. of sulfuric acid and 1340 lb. of sodium hydrode for each regeneration. An additional 2350 lb. of sodium hydroxide is required to neutralize the spent regenerants prior to discharge, resulting in 3270 lb. of neutralized sodium sulfate contained in approximately 70,000 gallons of water. Based upon a desineralized water use of 40,000 gallons per day and a production of 300,000 gallons between regenerations , this quantity would be released each 7.5 days. Release rates are based upon flow through the mechanical draf t cooling tower.
4 0
. W O
o .' ,
A mixed bed unit in th'e cycle makeup dcminaralizer uses 320 lb. of
. sulfuric acid and 800 lb. of sodiu= hydroxide for each regeneration.
An additional 72 lb. of sulfuric acid is required to neutralize the spent regenerants prior to discharge, resulting in 568 lb. of neutralized sodium sulfate contained in approximately 50,000 gallons --
of water._ Based upon a denineralized water use of 40,000 gallons per. day and a production of.2,000,000 gallons between regenerations.
this , quantity. w'ould"be re'1 cased 'each 50 days. Release rates are based upon flow throdgh the'~mechanica1 draft cooling tower.
The six Powdex condensate polishing units are of the wound element filter type precoated with powdered resin. The spent resin is back -
washed off the elements and treated in the same manner as clarifier sludge. With five of the six units in service during normal operation, and a 25 day service cycle for each unit, one unit would be backwashed each 5 days. This would result in 180 lb. of powdered resin to be pressed into dowatered blocks and the discharge of -
14,000 - 17,000 gallons of filtered, decineralized water to the cechanical draft cooling- tower.
3.2.2 Sulfuric Acid for Cooling Tower Circuits Sulfuric acid is added to the circulating water in the condenser cooling water circuits, for pH control, at an average rate of
.- 6,000 lb. per day. This acid forms sulfates with various cations 1,, in the cooling water and is eventually released with the 2,000 gps.
' blowdown from the cooling towers. This will result in an incremental ine case of approximately 23 ppm. sulfatos in the effluent returning to the river, assuming 18,000 gpa. flow through the mechanical draft cooling towers.
3.2.3 Concentration of Naturally Occurrin7, Salts In addition to the acid added to the cooling tower circuits there is a concentration of naturally occurring salts in the river water by about a factor of 5 dua to evaporation in the cooling towers. Assuming an average concentration of 238 ppa. for dissolved salts in the river water, the concentration in'the blowdown from the cooling towers would be approximately 1200 ppm. Assuming a cooling water flow of 18,000 ,
gpm. through thu mechanical draf t cooling tower this would result in an incremental increase of 120 ppm. dissolved salts in the effluent to the river.
3.2.4 Chlorination .
The water taken from the river is treated with approximately 100 lb.
per day of chlorine to control the growth of biological slimes in t
river water piping and heat exchangers. The chlorine vill be added in 15 min. periods-as dictated by biological growth. Up to an
(
~
additional 1000 lb. of chlorine will be injected into the condenser cooling circuits. Addition will be in 15 minute periods as dictated by biological growth. Chlorination periods for the condenser cooling circuits'and river water circuits will be staggered so that blowdown from the condenser cooling circuit will make a minimus contribu. tion ,.
to chlorine concentration at the riv'er water dis ~ charge. This y . . .
contribution to the river water discharge chlorine concentration will .
be even lower due 'to the fact that'any volatile chlorine components will be lost during passage through the natural draf t cooling towers.
3.2.5 Sanitary Wastes The sanitary waste treatment plant produces up to 10,000 gallons of treated sanitary wastes. Biological oxygen de=and is reduced by approxi=ately 93% in the aeration tanks and aerobic digester and is further reduced by the addition of sodium hypochlorite.
Phosphate reduction is accomplished by the addition of li=e which recoves approxi=ately 80% of the input phosphate. The final effluent of the treatment plant is mixed with effluent from the mechanical draft cooling tovet prior to discharge to the river.
3.2.6 Solid Wastes Suspended solids from the water treatment facilities are separated from the carrier water by filtration through diatomaceous carth pressure filters. The resulting slurry is further dewatered by pressing until the cake has a =oisture content of approximately 50% and the blocks are trucked offsite to an approved sanitary landfill.
Approximately once each mon'th an additional 1500-1700 lb. of cake will be produced as a result of processing sludge from the sanitary waste systa=. This waste is also trucked offsite for disposal in an approved landfill.
Trash collected from the river by the plant intake screens as well as solid wastes from the oil fired incinerator are also hauled offsite for disposai in a landfill.
