Monitor Information
Monitor Association
Forms: ME-01-R/ME-01
Use this page for Continuous Emissions/Opacity Monitors (CEMS/COMS), Continuous Parametric Monitors, and associated Data Acquisition Systems (DAS).
Note: Due to this screen’s design, it's critical that you click Save at least every 20 minutes while providing monitor information. If you do not, the screen will time out and you will lose all unsaved progress.
This page allows you to edit and add information for monitors at your facility. Answer the question “Are there Monitors at this facility?” If the answer is Yes, you may not continue until all mandatory fields are entered. Any SI removed during the e-Service process will not require entries in otherwise mandatory fields.
Note: This service does not have a point where you are prompted to provide changes to groups in your permit. If you have changes to permit groups, you may upload an “other” type document describing group changes when you reach the Attachments screen.
+Any SI removed during the e-Service process will not require the fields listed above.
DAS ID — For new or additional DAS, you will need to assign a unique ID for the purposes of this application process. Any ID you assign will most likely be different when the permit is issued. This ID number must be the same as shown on the Process Flow Diagram and must be used consistently throughout the application. ID numbers must be unique within your service. For example, you may not use the ID “0061” for a continuous opacity monitor and “0061” for a DAS. You could instead choose the ID “0061” for the COM and “DAS 0061” for the DAS. For replacement DAS, reuse the DAS ID of the equipment being replaced and edit the existing fields.
Description — Describe the DAS in sufficient detail to identify this DAS at the facility, for example, Boiler 1 Emissions Monitors. This field allows up to 120 characters.
Primary or Backup — Select if Primary or Backup.
Installation Date — Enter the date installed or replaced.
Status — Select the operational status from the drop-down list, either Active/Existing or Inactive/Retired. If the DAS was replaced, the replacement DAS will use the same ID and therefore the status is Active/Existing.
Removed Date — Required if the Status is Inactive/Retired. Provide the date that the monitor was removed, in the format MM/DD/YYYY. The allowable values range from 01/01/1900-12/31/3000. If the DAS was replaced, provide a replacement date and do not provide a removed date.
Manufacturer, Model, and Serial Number — Enter the manufacturer, model, and serial number.
Click Add Row to add information for a new DAS or monitor. You may edit some information in existing rows. These are rows that have been populated by data you have entered previously. For replacement monitors and DAS, you may reuse ID numbers and edit existing information. You do not need to add rows for replacements.
Click the Delete icon to erase a row that you have added. You may not delete existing rows (rows that you have not added during this application process). Instead, you may change the status to Inactive/Retired and provide a removed date.
You may not continue until all mandatory fields are entered.
+Any SI removed during the e-Service process will not require the fields listed above.

**Required only if CEMS is selected for Type.
***Required only if COMS is selected for Type.
Monitor ID — For new or additional Monitors, you will need to assign an ID for the purposes of this application process. Any ID you assign will most likely be different when the permit is issued. This ID number must be the same as shown on the Process Flow Diagram and must be used consistently throughout the application. Each monitored parameter at your facility will have its own ID. For instance, a monitoring system may measure SO2 and NOx simultaneously but both pollutants would have separate Monitor IDs.
ID numbers must be unique within your service. For example, you may not use the ID “0061” for an emission unit and “0061” for a COMS. You could instead choose the ID “0061” for the emission unit and “COMS 0061” for the COMS.
For replacement monitors, reuse the monitor ID of the equipment being replaced and edit the existing fields.
Description — Describe the Monitor in sufficient detail to identify this monitor at the facility, for example, Boiler 1 NOx or Boiler 1 Scrubber Flow Rate. This field allows up to 120 characters.
Type — Select whether the Monitor is a Continuous Emissions Monitor, Continuous Opacity Monitor, or Parametric Monitor. Select Continuous Opacity Monitor if the monitored parameter is opacity. Select Continuous Emissions Monitor when the monitored parameters are needed to calculate pollutant emissions. The Parametric Monitor option should be selected in all other situations. For example, the Parametric Monitor Type is selected when air flow is necessary to ensure compliance with a permit condition, such as “Air Flow Rate: less than or equal to 50,000 actual cubic feet/minute”.
Parameters Monitored —Select the parameter monitored from the list. Note: Parameter options will be filtered based on Monitor Type. Allowed parameters are listed in the tables below. Air Flow Rate is available in the Parameters Monitored field when either Continuous Emissions Monitor or Parametric Monitor is selected in the Type field. When Parametric Monitor is selected in the Type field, Air Flow Rate is listed as “Air”; when Continuous Emission Monitor is the selected Type, Air Flow Rate is listed as “Air Flow Rate”.

Do not use 1,2,3-Trimethylbenzene, 2-Butoxy ethanol, Ammonia, or Methyl ethyl ketone (MEK) as a "Parameter Monitored."
*If your only Parameter Monitored is Opacity, make sure the selected Type is continuous opacity monitor (COMS).
** CEMS/COMS are for direct measurement of emissions. If your monitored Parameter predicts emissions of a pollutant, include the parameter as a Parametric monitor.
Installation Date — Enter the date the monitor was installed or replaced.
Status — Select the operational status. If Removed Date is entered, Status must be Inactive. If the monitor was replaced, the replacement monitor will use the same ID and therefore the status is Active/Existing.
Removed Date — If removed, enter the date removed. Mandatory if Status is Inactive. If the monitor was replaced, provide a replacement date in the Installation Date field and do not provide a removed date.
Click Add Row to add information for a new DAS or monitor. You may edit some information in existing rows. These are rows that have been populated by data you have entered previously. For replacement monitors, you may reuse ID numbers and edit existing information. You do not need to add rows for replacements.
Click the Delete icon to erase a row that you have added. You may not delete existing rows (rows that you have not added during this application process). Instead, you may change the status to Inactive and provide a removed date.
You may not continue until all mandatory fields are entered.
Click Continue to access the Monitor Association page.
Primary or Backup - Select if Primary or Backup.
Bypass Capability - Indicate if there is a capability to bypass the monitor. For example, doyou have a vent stack that allows you to vent flue gases before they reach the monitor?
Certification Date — Enter the date the monitor was certified by the MPCA based on the requirements of Minn. Rule 7017.
Certification Basis - Select the regulatory standard under which the monitor was certified.
Manufacturer, Model, and Serial Number — Enter the manufacturer, model and serial number.
Span Value —Enter the upper limit of the gas concentration the monitor will measure in ppm. Certain standards and regulations like 40 CFR Part 60 (NSPSs) and performance specifications specify the span value. Otherwise, you can calculate the value by multiplying your proposed emission limit by 1.5. For a diluent CEMS with no emission limit, use the diluent upper bound value defined in rule. If a diluent upper bound is not defined, enter an appropriate span value based on expected diluent concentration.
System Full-Scale Value —In ppm, enter the highest measurement your monitor is capable of reading for a particular parameter.
Optical Path Length — Enter the length of the path of light your monitor employs. For single path monitors this is typically the inside diameter of the stack at the location of the monitor. For double pass monitors it is typically twice the inside diameter of the stack at the location of the monitor.
Note: If you are submitting an administrative amendment, you only need to provide association information for monitors affected by the amendment. Make sure to only select a Subject Item from the drop-down that is affected by your amendment.
It is mandatory to have an association row for each monitor entered previously. The monitor associations are only populated for one monitor at a time. You may move between the different monitors and associations at your facility by using the Previous Monitor and Next Monitor buttons.
A monitor must be associated with a DAS and a subject item.
Monitor — This drop-down box should contain the monitor you wish to associate with a data acquisition system and a monitored subject item.
Data Acquisition System — Select the data acquisition system from the drop-down list that the selected subject item sends data to. If the data acquisition system you wish to select is not present, first save any progress you have made. Then, navigate to the appropriate page (most likely the Monitors page) via the navigation panel on the left and make sure that the data acquisition system is added there.
Monitored Subject Item— Select the subject item from the drop-down list that the selected subject item monitors. If the subject item you wish to select is not present, first save any progress you have made. Then, navigate to the appropriate page (most likely the Emission Unit or Control Equipment page) via the navigation panel on the left and make sure that the subject item is added there.
SI Association Start Date —Provide the date on which the subject item began monitoring this subject item or sending data to this data acquisition system. The format for the date is MM/DD/YYYY. The allowable values range from 01/01/1900-12/31/3000.
SI Association End Date —Provide the date on which the subject item stopped monitoring this subject item or sending data to this data acquisition system. The format for the date is MM/DD/YYYY. The allowable values range from 01/01/1900-12/31/3000.
It is mandatory to have an association row for each monitor entered previously. The monitor associations are only populated for one monitor at a time.
Click Next to go to the next monitor. This action will take you away from the current page after all mandatory fields are entered. You will not be able to move to the next subject item if you are currently viewing the last item.
Click Previous to go back to the previous monitor. This action will take you away from the current page after all mandatory fields are entered. You will not be able to view the previous subject item if you are currently viewing the first item.
Click Add Row to add an association for a new DAS or monitor. You may edit some information in existing rows. These are rows that have been populated by data you have entered previously. You may use existing association information for replacement DAS and monitors as the SI IDs will not change for replacements.
Click the Delete icon to erase a row that you have added. You may not delete existing rows (rows that you have not added during this application process). Instead, you can change the status to Inactive and provide the date the monitor was removed.
