End of Current Month/Year Stocks: Report the tons or barrels of fuel on site at the end of the reporting period. Do not include fuels in transit. Do not leave blank. Enter zero if appropriate.
Adjustments to Stocks: Report fuel not accounted for by consumption on Schedule 3A to 3C. Adjustments to stocks include recalibration of stockpiles, transfers to and from central fuel storage terminals, sales
or transfers to other entities or plants or onsite use for purposes other than electricity generation. The adjustment should create a zero fuel balance for plants required to complete Schedule 2, fuel receipts.
Neither is the Balance applicable to Natural Gas or Hydrogen, which is not required on Schedule 4A. Adjustments to Stocks may be negative or positive. All adjustments must have a corresponding comment
entered at the bottom of the table.
Fuel Balance: The balance is applicable only to coal and oil stocks where Schedule 2, Fuel Purchases, is also reported. The balance for coal and oil stocks must be zero. If needed, enter an adjustment and
comment to bring the balance to zero. Balance is calculated as follows:

SCHEDULE 8. PART D. MONTHLY COOLING SYSTEM INFORMATION
Required Respondents: Thermoelectric power plants with a steam-electric nameplate capacity of at least 100 megawatts, including nuclear and combined cycle plants.
See instructions! An expanded section for detailed information by cooling system type has been added to the instructions. Report water use data for each month. Rates are to be
reported in gallons per minute (GPM). To convert water flow rates from cubic feet per second (CFS) to gallons per minute (GPM), use conversion factor: 1 CFS = 448.8 GPM. Report
volumes of water in million gallons. If actual data are unavailable use estimates.

Cooling System ID: The cooling system IDs are prepopulated from the IDs reported on the Form EIA-860. Contact EIA if changes are needed. If water use data cannot be reported for each system, use PLANT for the ID
and report aggregated data for the entire plant.
Cooling System Type: The types are prepopulated from the primary type as reported on the Form EIA-860. Contact EIA if changes are needed.
Cooling System Status and Hours in Service: Choose the status for each system from the drop down list. Report the hours in service during the month.
Amount of Chlorine (Elemental): Report the amount of elemental chlorine added to the cooling water system. To determine the elemental amount of chlorine in a compound, calculate the percentage by weight of
Chlorine using the atomic weight for each element in the compound. If unable to do this, provide the compound name on Schedule 9 and the pounds used.
Average Monthly Rate of Cooling Water: Report rate of water flow in gallons per minute for each point in the system as described below and in the instructions. If unsure of the definitions please see the instruction or
call EIA.
Diversion: The flow for water that is moved from a natural water body without immediate beneficial use for purposes such as filling a cooling pond, or adding water to a reservoir from which thermoelectric power water
withdrawals can occur.
Withdrawal: The water that is removed from a water body (including cooling ponds) for cooling i.e. water that is used through the condenser. For cooling towers this will be the makeup water.
Discharge: The water that is returned to a natural water body or multi-use reservoir (not a cooling pond). Cooling tower blowdown that is diverted to treatment or evaporation ponds is not considered Discharge. Water
that is returned to a water body from evaporative or blowdown treatment ponds is discharge. The water body may be a different water body from which the water was withdrawn. For zero discharge systems (recirculating
systems), report zero in the discharge field. Do not report the water discharged back into the cooling pond for recirculation.

Consumption: Water consumed through evaporative losses in cooling towers or cooling ponds. See the appendix illustrations for definitions specific to cooling system type.
Method of Measurement: Choose from the drop down list the method used to measure the flow rates or see instructions for a list of choices.
Cooling Water Temperature: Report the temperature in degrees Fahrenheit at intake and discharge points. Report an average monthly temperature and a maximum monthly temperature. If the source of cooling water is
a well or municipal water system, do not complete the Cooling Water Temperature sections.
Method of Measurement: Choose from the drop-down list the method used to measure temperatures or see the instructions for a list of choices.
Volume of Cooling Water: For each movement of water (Diversion, Withdrawal, Discharge, and Consumption, as described above) report the volume of water in million gallons per month (to the nearest 0.001 million
gallons).
