This page allows you to edit and add information for control equipment at your facility. Answer the question “Is there control equipment 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.
Control Equipment — Any equipment, device, apparatus, structure, operation, or other means of treating, preventing, collecting, or controlling air pollution. There are many examples of control equipment, including fabric or other media filters, thermal oxidizers, catalytic oxidizers, electrostatic precipitators, and dust suppression by water or chemical application.
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.
Click Add New Record to add information for a new method of control. You may edit some information in existing records. These are records that have been populated by data you have entered previously. You will not be able to edit existing control equipment‘s type, manufacturer, or model number.
Click Delete Record to erase a control that you have added. You may not delete existing records (records that you have not added during this application process). Instead, you may change the status to Inactive/Retired and provide a removed date.
Reason for changes/modifications — If you edit existing information, you must provide a reason in this text field (below the table). This field allows up to 2,000 characters.

Control Equipment ID — For new control equipment, the service will list “new” as the ID number. 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. Assign a new and unique subject item ID number to each additional piece of control equipment; do not reuse numbers. Even if the equipment or method replaces a previously removed device or method, assign a new number. This ID number must be the same as shown on the Process Flow Diagram and must be used consistently throughout the application. This field allows a maximum of 50 characters.
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 piece of control equipment. You could instead choose the ID “0061” for the emission unit and “Scrubber 0061” for the control equipment.

Description — Describe the control equipment in sufficient detail to identify this source at the facility; for example: “panel filter for main paint booth,” “water application on road from mine to North Crusher,” etc. This field allows up to 200 characters.
Manufacturer — For packaged and pre-assembled equipment, and for equipment completely designed by a single company and field-assembled, provide the name of the manufacturer or designer. For equipment designed and manufactured by the contractor or owner, indicate this. Up to 50 allowable characters.
Model Number — For equipment which has a model number, provide the model number. If there is no model number, you may enter NA or something similar to indicate that there is no model number. Up to 50 allowable characters.
Status — Select either Active/Existing or Inactive/Retired from the drop-down list.
Installation Date — Provide the date that construction or installation of the control equipment began. For equipment with an unknown construction date, select the TBD (to be determined) check box. The format for the date is MM/DD/YYYY. The allowable values range from 01/01/1900-12/31/3000.
Removal Date — This is required if the Status is Inactive. Provide the date that the equipment was removed. The format for the date is MM/DD/YYYY. The allowable values range from 01/01/1900-12/31/3000.
Pollutant Controlled — You must select at least one pollutant that is controlled by the control equipment. If the equipment controls more than one pollutant (e.g., PM, PM10, and PM2.5), then click Add Row to include additional pollutants. Click the Delete icon to remove a row that you have added through this application process.
Capture Efficiency — Fill in the capture efficiency of the emission capture device. The capture efficiency is the portion of the pollutants emitted that are routed via ducting to the control equipment. If all of the pollutants emitted are routed via ducting to the control equipment, the capture efficiency is 100%. Hoods and other devices that do not completely surround the emissions from an emission unit do not capture all of the pollutants emitted have a capture efficiency that is less than 100%.
If the capture efficiency has been determined by performance testing in accordance with Minn. R. 7017.2001 to 7017.2060, and the test report has been reviewed and approved by the MPCA, the determined efficiency must be used. If the capture efficiency has not been determined by a performance test, but the capture device is a hood that has been evaluated and conforms with the requirements of "Industrial Ventilation - A Manual of Recommended Practices," 21st ed., fill in 80% for particulate matter or 60% for volatile organic compounds. Hood evaluations must be conducted by qualified personnel. You must use the Hood Evaluation and Certification form (CR-02). The Hood Evaluation and Certification form (CR-02) must be signed by a responsible official and must be submitted with the application. This form is required for existing and newly listed control equipment and must be uploaded when you reach the Attachments page. These forms are available on the MPCA’s website at https://www.pca.state.mn.us/business-with-us/air-permit-application-forms.
Hoods that have not been evaluated or do not conform to the recommended design and operating practices in "Industrial Ventilation- A Manual of Recommended Practices", 21st ed., must be either evaluated and brought into conformity with those design and operating practices or tested in accordance with Minn. R. 7017.2001 to 7017.2060, and the test report reviewed and approved by the MPCA, to determine a capture efficiency. You may propose an alternative capture efficiency based on engineering calculations approved by the commissioner; the CR-02 form must still be completed and submitted with the application.
The results of the evaluation and a copy of the certification must be kept on-site. The owner or operator must make this evaluation and certification available for examination and copying upon request of the commissioner and must, upon request, submit these records to the commissioner by the time specified in the request.
Destruction/Collection Efficiency — The collection or destruction efficiency is the portion of the pollutants that are captured and routed to the control equipment that is either collected and retained in the control equipment or is destroyed by the control equipment. Environmental Protection Agency publications and databases are the preferred sources for destruction/collection efficiency factors.
If you conducted a performance test that was reviewed and accepted by the MPCA, you may propose that efficiency.
Efficiency Basis — You must indicate the basis of the destruction/collection efficiency you entered. You must select from the drop-down list.
If other basis, please explain — If you select Other as the efficiency basis, you must complete this field. Describe the efficiency basis. Up to 200 allowable characters.
Subject to CAM? — You must indicate whether or not the control equipment is subject to Compliance Assurance Monitoring (CAM) regulations (40 CFR Part 64). Refer to MPCA Form GI-09H to make this determination. Select Yes or No from the drop-down list. If you answer Yes and CAM newly applies, you must upload a Compliance Assurance Monitoring Plan when you reach the Attachments page.
For large or other PSEU? — PSEU stands for Pollutant Specific Emission Unit, and it means an emission unit considered separately with respect to each regulated air pollutant that is controlled by a specific piece of control equipment. If you answered Yes to “Subject to CAM?” you are required to indicate here if the controlled subject item is a large PSEU (meaning the controlled emission rate of the specific pollutant exiting the control equipment is 100 tons per year or more), or an other PSEU (meaning the controlled emissions are less than 100 tons per year). Select Large or Other from the drop-down list.

TopNote: If you are submitting an administrative amendment, you only need to provide association information about control equipment affected by your amendment. Make sure to select a Subject Item only from the drop-down that is affected by your amendment.
Each piece of control equipment must be associated with at least one subject item.
Subject Item — This drop-down box should contain the subject item (emission unit, fugitive source, or storage tank) you want to associate with control equipment.
The following information applies to each line in the grid for the selected subject item. For example, if you have two lines in the grid (using the below example of the emission stream split between two control devices/methods), you would follow the same instructions for each line of the grid.
% Flow — If all emissions flow to one control device/method, or to two or more control devices/methods in series, this will be 100. If the emissions stream is split and flows to two or more control devices/methods in parallel, this number will be less than 100 and you will need a separate line for each stream; click Add Row to add lines. The allowable values range from 0.00 – 100.0. The % Flow for all rows in the grid should add up to 100. Do not use the % sign when entering % flow.
For example, if the emission stream is split and flows through two separate control devices, and the air flow to each control device is the same, you would enter 50 for the % Flow, click Add Row to enter a line for the other half of the flow, and enter 50 for the % Flow for that line.
