Compliance Reporting Requirements for Injection Well Owners and Operators, and State Regulatory Programs
On this page:
Compliance data collection
EPA collects monitoring data and test results from operators of Class I, II, III, V, and VI injection wells.
Each well class has specific information collection requirements. In general, Class I, II, III, and VI owners or operators must:
- Submit permit applications
- Monitor their wells and report the results
- Submit plugging and abandonment reports when they close their wells
Class V operators submit a small subset of the information required of Class I, II, III, and VI well operators. Class IV wells are banned—except when they are authorized by the Resource Conservation and Recovery Act (RCRA) or Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).
Class VI well operators are required to submit compliance data directly to EPA in an electronic format approved by EPA. This requirement applies regardless of whether the project is located in a state with primary enforcement responsibility (primacy) for Class VI wells. The Geologic Sequestration Data Tool (GSDT) is EPA’s centralized, web-based system that received, stores, and manages Class VI data to fulfill this requirement. Visit Class VI – Wells used for Geologic Sequestration of CO2 for additional information and resources related to the GSDT.
Reporting forms
Reporting forms, known as the 7520 forms (for their Office of Management and Budget number), are how EPA and primacy states collect and report the information used to determine whether injection wells are operating properly and protecting public health.
There are two categories of 7520 forms.
State summary forms are prepared by the agency with primary enforcement authority, either the primacy state, or the regional EPA direct implementation (DI) program. After completion, the forms are submitted to the national UIC program. The national UIC program uses the information to track, evaluate, and report on program performance.
Owner or operator UIC program forms are prepared by owners or operators and submitted to the agency with primary UIC enforcement authority (primacy):
- States with primacy
- Regional EPA program for states, tribes, or territories where EPA directly implements the UIC program

Options for reporting by primacy states and EPA programs
As of April 1, 2019, UIC well inventory and Forms 7520-1, -2A, -2B, -3, and -4 should be submitted to EPA using the UIC Data Application found at https://uicdata.epa.gov. Programs should visit Resources for Transition to the New UIC Data Reporting Process for user support resources and instructions on accessing the new web-based application.
