This tool provides access to information for sources affected by 40 CFR Part 75. Location, ownership and contact information, unit attributes, and monitoring plan data is presented for each facility.

What is in a monitoring plan?

The monitoring plan describes how a facility monitors its emissions. Monitoring plan data define relationships between stacks, pipes, and units; specify locations at a facility from which emissions are monitored; and identify monitoring equipment including the individual system components. Monitoring plan data also provide characteristics of operations and physical and unit characteristics such as stack height, cross sectional area, fuel type, air pollution control devices, and size of the unit(s).

How to Access

To view more information, select a facility from the list on the left. A series of tabs will be displayed. To view the monitoring plan, open the "Monitoring Plans" tab and select a unit and/or stack from the list.

Sorting and Filtering

The facility list can be sorted in ascending or descending order by selecting a column heading. Additionally, the facility list can be dynamically filtered according to the search box content. Sorting and filtering applies to ORIS Code, Facility Name, and State.
