Air Emissions Inventory — Electronic Reporting

Go to the e-Services electronic reporting website to report your air emission inventory electronically. 

Note: If you are having trouble accessing the e-Services electronic reporting website, please check your computer/network security settings to ensure that the settings are not blocking access to the e-Services site. If after checking/ adjusting the security settings you are still unable to access the website, please call Kou Vang for technical support at 651-757-2794.  

Instructions for using e-Services

Setting up a user account and Responsible Official/Submitter registration. If your facility holds a registration Option C, Option D, or a Large Inventory Type Permit, you will submit your 2011 Emission Inventory (EI) electronically. (Facilities holding a registration Option B, or a nonmetallic general permit will submit their inventories by hardcopy mailing as in previous years.)

To be able to use the system, the Responsible Official/Submitter for your facility, as defined in Minn. R. 7007.0100, subp. 21 must sign up for an account through the e-Services electronic reporting website and submit a signed paper Emission Inventory Report (EIR) User Agreement (Submittal Agreement) to the MPCA. According to Minn. Rules, the Responsible Official/Submitter is the only person that can submit the inventory, thus a signed paper agreement is needed to allow for electronic signature and submittal. Please allow up to 2-3 weeks to process this agreement given the volume of new users.

Others assisting the Responsible Official/Submitter with the preparation of the inventory (Preparers) can create an account at any time through the e-Services electronic reporting website by following the steps under "Create User Account" below. Preparers will be able to assist with preparing the emission inventory submittal; however, they will not have access to the facility information until access is granted by the Responsible Official/Submitter.

Create User Account (Preparers and Responsible Officials)

1. Go to e-Services website. 
2. Select "Create an Account" and complete the information requested. You will receive an e-mail with your account number. Click the link in the e-mail to activate your account.

Apply for Responsible Official/Submitter Designation (Responsible Officials/Submitters Only)

What's New for Emissions Inventory Reporting?

PM Emission Factor Updates from EPA for Natural Gas, Process Gas, and LPG

Particulate matter emission factors for natural gas, process gas, and LPG have been revised by Roy Huntley of the EPA. The reason for this adjustment is that the EPA believes that the current AP-42 factors for condensable PM emissions are too high. The electronic emission inventory reporting website (e-Services) will perform calculations using the revised EPA emission factors from Roy Huntley as the default emission factors. The unrevised emission factors will still be available in AP-42/WebFIRE. Please select the link below based on your facility’s air permit type to reference the updated emission factors. An explanation of this issue can be found on the EPA’s National Emission Inventory (NEI) website.

• Option C and Option D registration permittees revised natural gas, process gas, and LPG emission factors
  • Revised PM Emission Factors-Nat. Gas Combustion — Small EI Type (aq-ei1-08)
• Large Inventory Type Permit holders revised natural gas, process gas, and LPG emission factors
  • Revised PM Emission Factors-Nat. Gas Combustion-Large EI Type (aq-ei1-07)

What’s New for 2011 Emissions Reporting for Large Facilities?

• Submit Air Toxics Emissions. 2011 is an air toxics reporting year. If you have site-specific toxics emissions information, you will report that information along with your criteria emissions information at a single website. Emissions of toxics and criteria pollutants must be reported through the CEDR web application by May 1, 2012. 
• Greenhouse Gas (GHG) Emissions: Facilities holding a Capped Permit or a part 70 Title V permit will be required to report GHG emissions to the MPCA starting with the 2011 emission inventory year unless the facility is required to report GHGs to EPA under the Mandatory Reporting Rule. The MPCA's new electronic reporting system will automatically calculate GHG combustion emissions using EPA methodology. Facilities will have the ability to view combustion emissions data during the summary review period and report site-specific information.
• Updated Criteria Pollutants. The EI report will include ammonia, PM2.5 filterable, PM10 filterable, PM filterable and PM condensable. EPA is now requiring emission inventory data to be submitted with Particulate emissions separated into filterable and condensable portions, each fraction will now be calculated separately. If your Particulate emissions are calculated using default emission factors, the system will automatically calculate these emissions separately. Facilities with Particulate performance test emission factors will now split the emission factor into filterable and condensable portions.
• EI Information Available for Facility Review. Electronic submitters will report information needed to allow the MPCA to supply US EPA the required information for their facility. Forms will be pre-populated with information to allow a facility to update and review. Some of the new elements for review on the 2011 EI include: Release Point (stack vent) coordinates, and prefilled imitation release point association.
• Review Emission Inventory Prior to Submittal Facilities will be able to review process and whole facility emission totals by process, for ease of review prior to submittal.
• Downloadable Spreadsheet No Longer Available Due to feedback that the MPCA received from facilities during 2010 EI reporting a downloadable spreadsheet version of the inventory will not be made available for 2011 EI reporting. Numerous enhancements have been made to the MPCA e-Services electronic reporting website since the 2010 EI reporting period ended. These enhancements should make the online experience more user-friendly.

What’s New for 2011 Emissions Reporting for Small Facilities?

• Electronic Reporting. The MPCA’s e-Services website will be used for electronic inventory reporting by registration Option C and Option D permit holders and includes the feature of an electronic signature. The electronic system will differ slightly from the paper forms but will still use the same information facilities are collecting to calculate their emissions.
• All emission inventory pollutants submitted in one system. Facilities will be able to go to a single website to report all of their emissions. The system will also automatically calculate combustion emissions for criteria pollutants based on throughput, if applicable.
• Air Toxics Emissions. 2011 is an air toxics reporting year. If you have a registration Option D permit and site-specific toxics emissions information, you will report that information along with your criteria emissions information at a single website. Emissions of toxics and criteria pollutants must be reported through the CEDR web application by May 1, 2012.
• Greenhouse Gas (GHG) Emissions: Facilities holding an Option D Registration Permit will be required to report GHG emissions to the MPCA starting with the 2011 emission inventory year unless the facility is required to report GHGs to EPA under the Mandatory Reporting Rule. The MPCA's new electronic reporting system will automatically calculate GHG combustion emissions using EPA methodology, but facilities will have the ability to report site-specific information. 
• Review Emission Inventory Prior to Submittal Facilities will be able to review facility emission totals, for ease of review prior to submittal.

Air Emissions Inventory Redesign Project: CEDR — Consolidated Emissions Data Repository

What is CEDR?

CEDR, the Consolidated Emissions Data Repository, is the name for the emissions inventory system that is being designed to replace the existing emissions inventory system at the MPCA.

Diagram showing merger of existing emissions inventory system into new system

Why is the emissions inventory system being redesigned?

The redesign is being driven by the recent reduction in time that states have to report inventory data to the EPA.  New state and federal rules are also increasing the need for the state to improve tracking of greenhouse gases and mercury.  It will be difficult for inventory staff to meet the requirements of the new reporting deadline and the new legislative requirements without having a more streamlined system.

What will be the benefits of the new emissions inventory system?

The new emissions inventory system will allow facilities to report their air emissions electronically.  Facilities will be able to go to a single website to report their emissions data for criteria pollutants, air toxics, and greenhouse gases instead of having to complete multiple forms for each pollutant category.  Also CEDR will allow electronic signatures so that facilities do not have to mail in signed hardcopy forms.

Electronic reporting will also improve the quality of the data in the repository by reducing the potential for errors resulting from the reliance on manual data entry that is prevalent in the current system.  The ability of facilities to submit data online will reduce the time it takes for the data to get into the system and as a result all users of the repository will gain access to this data more quickly.

When will CEDR be ready for use?

Projected completion dates:

• Phased implementation of electronic reporting functionality
• Entire system redesign by March 2012

For the electronic reporting, the MPCA is working on a phased implementation plan. Large facilities (those that have individual permits and capped permits) submitted their 2010 Emission Inventory electronically. Smaller facilities with registration Option C or Option D permits will begin reporting electronically with the 2011 inventory that is due by May 1, 2012. Facilities with registration Option B permits or nonmetallic general permits will continue to submit paper inventories for the 2011 emission inventory year by April 1, 2012.

The MPCA's e-Services portal will be used for electronic inventory reporting and includes the feature of an electronic signature as well as the ability to submit data using pre-populated excel spreadsheets.

The MPCA e-Services electronic reporting website will be used for electronic inventory reporting and includes the feature of an electronic signature.

*Facilities that are required to report GHG emissions to U.S. EPA under 40 CFR Part 98 are not required to report GHG to the MPCA.
