7/23/20 COVID-19 UPDATE: 

Badger Bounce Back Phase 2

Thank you for your patience during the COVID-19 public health emergency. As state agencies continue operations, please understand that most of our staff are continuing to telework and may have limited access to files and delayed online connectivity. The department is following the Badger Bounce Back [exit DNR] plan's phased approach to the resumption of activities that have been delayed or put on hold due to Safer at Home.

Now that the department has entered phase 2 of the plan, programs will continue the transition back to field work – including compliance inspections – that began in phase 1. In most cases, staff will continue to schedule pre-inspection calls with facilities to gather some of the information that would previously have been collected while on-site. These advance calls will also be used to discuss safety protocols for on-site visits that may be needed to complete all aspects of a compliance assessment.

Staff will keep their voicemails and out-of-office messages up to date and will respond as they are able.

Owners or operators of industrial sources that emit pollutants to the atmosphere need to get an air permit. A permit protects public health and the environment by requiring that owners or operators comply with all applicable state and federal air regulations. The DNR provides assistance to businesses, industry and the public to help better understand air permits, including when a permit is needed, the review process, applicable regulations, air quality modeling requirements and how to apply for a permit.
