Notes from Site Visit at the AES Cayuga Generation Plant on May 21, 2007 

EPA conducted a site visit at the AES Cayuga Generation Plant on Monday, May 21, 2007 to 

learn about the operations at the plant and determine where and how samples would be collected 

if the plant was selected for sampling. Table 1, at the end of this memorandum, identifies the 

site visit participants. 

This memorandum summarizes the information collected during the site visit, a pre-site visit 

phone call held on May 10, 2007, and a June 22, 2007 letter from John Marabella (AES Cayuga). 

Overview of the Plant 

• New York State Electric and Gas (NYSEG) sold the Cayuga plant to AES in 1999 

(the plant was formerly named Milliken Station). 

• The plant operates two units, each with a capacity of about 150 MW and tangentialfired boilers. Unit 1 came on line in 1955 and Unit 2 came on line in 1958. 

• Cayuga is a baseload plant and it typically operates at full capacity. 

• The plant plans to shut down Unit 1 for a couple of weeks in October. During that 

shutdown, the plant expects to reduce the flow rate of the FGD absorber blowdown to 

half of the typical flow rate. The plant expects to maintain the chlorides 

concentration in the FGD absorber between 20,000 and 25,000 ppm, rather than the 

typical 15,000 to 17,000 ppm. There are no other planned outages for 2007. 

• The plant burns about 2,500 tons of Eastern Bituminous coal per day. The coal 

originates from lower Pennsylvania, West Virginia, and Eastern Ohio. Units 1 and 2 

burn the same coal (or mixture of coals). The sulfur content of the coal ranges from 

1.8 to 3.5%, with an approximate average of 2.5%. 

• The plant operates an ESP on each unit. 

• The plant operates an SCR on Unit 1 year round. 

• The plant operates a dry fly ash handling system. Some of the fly ash is marketable. 

• The plant operates a wet bottom ash sluice system. Bottom ash is sluiced from the 

boiler hoppers to hydrobins (i.e., “decanting system”) in a batch process. The 

decanted water is transferred to a decant tank. Plant personnel estimated that about 

700 gpm of the bottom ash sluice water is recycled and 300 gpm is makeup water 

from the house service water system. The overall system flowrate is approximately 

1,000 gpm. Plant personnel stated that the plant does not test water that is used as 

bottom ash sluice because the water quality does not matter. The plant transfers 

wastewater from the bottom ash sluicing system (the plant refers to this as “leakage”) 

to the Process Water Reclamation Facility (PWRF), which is discussed in the “Other 

WWT” section. 

• The plant pulverizes coal on site and removes the pyrites generated using a hydrovac 

system, in which a vacuum is created with a venturi jet. Wastewater from this system 

is transferred to the PWRF. The pyrites are transferred to the on-site ash landfill or to 

the coal pile. 

• The plant pulls its intake water from Cayuga Lake and does not treat this water. The 

intake water is pumped through strainers to prevent zebra mussels from entering the 

system. The plant uses the Cayuga Lake intake water for process water, including 
- 2 -

once-through cooling water, and does not add chemicals to control biofouling or 

zebra mussels. The plant mechanically removes zebra mussels by backwashing. 

FGD System 

• The plant operates a wet FGD scrubber with two absorber compartments: one 

absorber for each generating unit. The scrubber came on line in 1995. 

• The FGD scrubber is a three-level spray tower (all three levels are typically operated 

at one time), in which limestone is used as the sorbent. 

• Forced oxidation is used in the scrubber system. 

• Formic acid is added to the scrubber, which increases SO2 removal efficiency from 

about 95% to 98-99%. 

• The plant maintains 8 to 13% solids in the scrubber. The plant maintains the 

chlorides concentration below 20,000 ppm; however the absorber material of 

construction (rubber-lined tile) can withstand 40,000 ppm chlorides. 

• The plant controls the chlorides and solids level with a continuous blowdown stream 

from each absorber compartment. The blowdown streams from the two absorber 

compartments are combined and transferred to primary hydrocyclones. Plant 

personnel explained that the primary (and secondary) hydrocyclones contain two 

separate banks of hydrocyclones, which would allow the plant to keep the two 

blowdown streams separate throughout the solids separation process. The plant 

currently has no need to operate in that fashion, however, because the two generating 

units are operated similarly (i.e., they burn the same type of coal and operate at 

capacity) and gypsum is generated from each blowdown stream. 

• Underflow from the primary hydrocyclones is transferred to centrifuges, in which 

gypsum is separated. The dried gypsum is sold. 

• Overflow from the primary hydrocyclones is transferred to a secondary feed tank. 

Water from the secondary feed tank is transferred to secondary hydrocyclones when 

they are operating, which is typically 8 to 10 hours per day. When the secondary 

hydrocyclones are not operating, water from the secondary feed tank is transferred to 

the filtrate sump. 

• Underflow from the secondary hydrocyclones is transferred to the filtrate sump, in 

which an “absorber module” filters the fine gypsum particles. Water from the filtrate 

sump is continuously recycled back to the scrubber. 

• Overflow from the secondary hydrocyclones typically contains less than 1% solids. 

This overflow is transferred to two clarified water tanks, which are connected 

together. These clarified water tanks are each 60,000 gallons and agitated. 

• From the clarified water tanks, water is recycled as limestone ball mill makeup. A 

bleed stream from the clarified water tank is transferred continuously to the FGD 

WWT system at a flow rate of approximately 30 gpm. The residence time in the 

clarified water tanks is about 72 hours.

FGD WWT 

• Wastewater is transferred continuously from the clarified water tanks to the first unit 

of the FGD WWT system, the equalization tank. 

• Wastewater is transferred continuously at approximately 30 gpm from the 

equalization tank to the pH elevation tank. In the pH elevation tank, lime slurry is 

added to raise the wastewater pH to about 10.7 and initiate metal hydroxide 

precipitation. 

• Wastewater is transferred from the pH elevation tank to the “heavy metals 

precipitation tank”, which is an outdated name. Organosulfide is no longer added to 

the heavy metals precipitation tank and wastewater simply passes through the tank. 

Organosulfide was only added to the heavy metals precipitation tank for one year 

during Infilco Degremont’s startup performance guarantee testing of the FGD WWT 

system. During the guarantee testing, the plant sampled at the influent and effluent of 

the FGD WWT system, analyzing for “all” metals (total metals). After the guarantee 

testing, the plant found that organosulfide addition was not necessary to maintain an 

acceptable wastewater turbidity level (or to meet their limits, which are discussed in 

the following section). 

• Wastewater is transferred from the heavy metals precipitation tank to the coagulation 

tank. The plant adds ferric chloride continuously to the coagulation tank, and has 

done so for about one year. Plant personnel did not know the exact addition rate, but 

knew that the plant uses approximately 1.5 drums (55 gallon drums) of ferric chloride 

per month. Prior to one year ago, the plant added ferric chloride intermittently to the 

coagulation tank for a period of a few months. During that time, the plant 

experimented with system variables to optimize the FGD system and maintain a low 

enough wastewater turbidity to allow recycle (less than 5 to 7 NTU). The plant 

determined that increasing the absorber pH to approximately 10.7 decreased the 

turbidity to the target level. Currently, plant personnel doubt whether ferric chloride 

addition is necessary to maintain an acceptable wastewater turbidity level, but plan to 

continue adding ferric chloride because the system is operating smoothly. 

• Wastewater is transferred from the coagulation tank to the Densadeg unit. The 

Densadeg unit consists of three sections/compartments: a reactor section, a thickener 

section, and a clarifier section. Wastewater enters the Densadeg unit at the bottom of 

the reactor section where it is mixed with a polymer flocculant. The water flows 

upward through this reactor section and enters the thickener section. In the thickener 

section, water is forced downward by a system of baffles and floc particles settle at 

the bottom of the thickener section by gravity. The sludge at the bottom of the 

thickener section continues to thicken and is pushed into a center well by a rotary 

scraper. Water travels upward from the thickener section into a clarifier section 

where particles settle out in lamella modules. 

• Wastewater from the clarifier section of the Densadeg unit is either transferred to a 

storage tank or transferred directly to the PWRF. This wastewater flow rate is 

typically between 30 and 40 gpm (difference from lime slurry and polymer addition). 
- 4 -

• Sludge from the Densadeg unit is transferred to a sludge holding tank. Sludge can be 

recycled from the sludge holding tank to the reactor tanks as seed, but this is not 

typically done. Sludge is transferred from the sludge holding tank to a filter press. 

• Wastewater from the filter press is recycled to the equalization tank. 

• Plant personnel estimate the total residence time for the FGD wastewater treatment 

system is 16.7 hours. 

Sampling Information 

• The FGD WWT system influent sample could be taken at a sample tap between the 

clarified water tanks and the equalization tank. This point is effectively between two 

equalization stages prior to FGD WWT. Figures 1 and 2 present photos of the sample 

tap at the exit of the clarified water tanks. 

• Alternatively, the FGD WWT system influent could be sampled off the top of the 

equalization tank. Figure 3 presents a photo of the top of the equalization tank. 

• The FGD WWT system effluent could be sampled at the tap where the plant samples 

for turbidity. “Blowdown” from the FGD WWT system occurs two times per day for 

about three to four hours. Flow is continuous during those two periods. Plant 

personnel stated that operators manually begin the blowdown process and could 

coordinate with EPA/ERG samplers. Figures 4 and 5 present photos of the FGD 

WWT system effluent sample tap. 

• The plant operates flow meters at the potential sampling points for the FGD WWT 

system influent and effluent. 

• The plant stated that there would be sufficient space for a sampling staging area. 

EPA/ERG could either use the control room or office space. 

• Samplers could either use the main boiler lab or the FGD lab for preservation. There 

may only be a small amount of space available in the FGD lab. 

• The plant stated that a FedEx pickup occurs daily at the plant loading dock. 

Other WWT 

• The plant operates a WWT system for coal pile runoff and maintenance cleaning 

washwater (CPR WWT system). Coal pile runoff is collected in a settling pond. 

Water flows by gravity from the settling pond to a 500,000 gallon, concrete collection 

basin. Water from the collection basin is either transferred directly to the CPR WWT 

system or to the maintenance cleaning washwater tank and then to the CPR WWT 

system. A portion of the maintenance cleaning washwater is air heater washwater. 

The plant generates about 200,000 gal of air heater washwater twice per year. The 

plant is prepared to accept coal pile runoff and maintenance cleaning waste from 

other facilities (by tanker truck) in emergency situations and treat this water in the 

CPR WWT system. The first stage of the CPR WWT system is a pH adjustment 

reactor, in which lime slurry and air is added. Water is transferred from the pH 

adjustment reactor to a floc tank, in which polymer is added. The pH of the influent 

to the pH adjustment reactor varies, but is typically around 7. The pH is typically 

about 8.6 in the floc tank. Sludge from the floc tank is transferred to the FGD WWT 
- 5 -

system filter press. The filter press is used on an alternating basis for the FGD 

wastewater and the coal pile runoff. 

• Process water/wastewater streams from the plant, including effluent from the coal pile 

runoff and FGD WWT systems, are sent to the PWRF. The PWRF includes oil/water 

separation (API separators), dewatering/solids separation, alum addition, and sand 

filtration. 

• Wastewater from the PWRF (Outfall 001B) is combined with once-through 

condenser cooling water. This combined stream is then combined with wastewater 

from the sanitary waste treatment system and discharged through the plant’s final 

outfall, 001. 

Monitoring 

• The plant does not have monitoring data that could be used to compare the 

characteristics of the FGD WWT effluent with and without ferric chloride addition. 

• The plant only measures turbidity and pH at the effluent of the FGD WWT system. 

At that point, the turbidity is typically 1 to 2 NTU (the plant does not have TSS data) 

and the chlorides concentration is approximately 20,000 ppm. 

• The plant samples wastewater at the effluent of the PWRF, Outfall 001B (prior to 

commingling with cooling water) for limited pollutants. The wastewater is monitored 

for oil and grease, aluminum, TSS, and chlorides. 

• Outfall 001B is sampled weekly. See attached spreadsheet for sampling data.
