15Criteria for Permit Approval Comply with emission limitations.Comply with air quality standards using dispersion modeling analysis.Standards include the NR 404 National Ambient Air Quality Standards or NR 445 Acceptable Air Concentrations for hazardous air pollutants.Comply with current policies.Wingra Engineering, S.C.
16Typical Permit Schedule Week 1 – Submit application to DNRWeek 5 – Receive DNR request for information.Week 7 – Respond to request for information.Week 11 – DNR issues draft permit and PD.Week 12 – Publish notice for public comments.Week 16 – Public comment period ends.Week 18 – DNR issues final permit and invoice.Wingra Engineering, S.C.
17Expedited Permit Issuance Pre-application meeting with DNR.Submit a complete application.Anticipate DNR application review needs.Provide emission calculations.Comply with applicable requirements.Conduct DNR modeling & risk analyses.Prepare environmental assessment.Anticipate public involvement.Task force on expedited permits suggested applicants submit application in PD format to minimize DNR staff effort.Low profile or be pro-active and schedule hearing at start of public comment period.Wingra Engineering, S.C.Wingra Engineering, S.C.
