Ventilation Quarterly

Please see Reporting Form Instructions on downloading the blank reporting form and uploading the completed reporting form.

Table 4 Instructions: Fill out the table for ventilation monitoring points on a quarterly basis; fill out four rows (quarters) for each monitoring point. Calculation support for Equation FF-1 is not provided because not all equation inputs are collected. Calculation support is provided for Equation FF-2 in Table 10a on tab 10. Calculation support is provided for Equation FF-4 in Table 10b on tab 10.

The table below includes space for 600 rows. If more are needed, contact the GHG Help Desk.

Complete the table from top to bottom and left to right without skipping rows. The pick list in the first column links to a previous sheet, to restrict entry to previously entered ventilation monitoring points.

For perspective the entire table width, 26 columns, is presented below. Enlarged views of this table presented below the perspective view.

The following example shows the first 8 columns:

• Ventilation Monitoring Point that corresponds to centralized monitoring point or individual shaft from previous tab Select from the pick list
• Quarter Select from the pick list
  • Dates where active ventilation of mining operations is taking place (start date and stop date).
    • If there was continuous venting during the quarter, insert the first date of the quarter in the column labeled "Start date" and insert the last date of the quarter in the column labeled "Stop date". If there were interruptions, include as many rows as needed for the ventilation monitoring point/quarter combination.
• Method used for flow rate Select from the pick list
• Quarterly volumetric flow rate used in Eq. FF-1
• Units for parameter V, quarterly volumetric flow rate Select from the pick list
• Length of time that substitute data are used for the quarterly volumetric flow rate used in Eq. FF-1

The next example shows the next 8 columns:

• Location of each measurement of flow rate used in Eq. FF-1
• Date of each measurement of flow rate used in Eq. FF-1.
  • For CEMS measurements, only include the first date of the quarter.
• Dates when continuous monitoring equipment for the flow rate is not properly functioning, if applicable (start date and stop date).
  • You are required to complete these columns only if you indicated CEMS (method 3) as your measurement method. Insert the first date of the episode in the column labeled "Start date" and insert the last date of the episode in the column labeled "Stop date"; include as many rows as needed for the quarter. If CEMS was not used during the quarter, or if CEMS was functioning properly during the quarter, you are not required to enter any information in these columns.
• Method used for concentration Select from the pick list
• Quarterly CH4 concentration used in Eq. FF-1
• Was Eq. FF-9 required to calculate CH4 concentration Select from the pick list
  • If yes, provide the gaseous organic concentration correction factor, used in Eq. FF-9

The next example shows the next 6 columns:

• Length of time that substitute data are used for the quarterly CH4 concentration
• Location of each measurement of concentration
• Date of each measurement of concentration
• Dates when continuous monitoring equipment for the concentration is not properly functioning, if applicable (start date and stop date).
  • You are required to complete these columns only if you indicated CEMS (method 3) as your measurement method. Insert the first date of the episode in the column labeled "Start date" and insert the last date of the episode in the column labeled "Stop date"; include as many rows as needed for the quarter.
  • If CEMS was not used during the quarter, or if CEMS was functioning properly during the quarter, you are not required to enter any information in these columns.
• Temperature used in Eq. FF-1

The final example shows the last 6 columns:

• Length of time that substitute data are used for the temperature used in Eq. FF-1
• Pressure used in Eq. FF-1
• Length of time that substitute data are used for the pressure used in Eq. FF-1
• Moisture content used in Eq. FF-1
• Length of time that substitute data are used for the moisture content used in Eq. FF-1
• Quarterly CH4 liberated from ventilation monitoring point
