Frequent Questions

What is the RCRA streamlined permit modification procedure?

We established the RCRA streamlined permit modification procedure to facilitate compliance with the Phase 1 HWC NESHAP (Appendix I to 270.42 section L.9). The streamlined permit modification procedure allows facility owners or operators to request changes necessary to meet the Phase 1 HWC MACT standards as a class 1 modification that requires prior Agency approval. Class 1 requests typically are processed much more quickly than class 2 or 3 modifications, which would be required if the streamlined procedure had not been established. Before requesting a permit modification under the streamlined procedure, facility owners or operators must have first complied with the requirements governing the Notification of Intent to Comply (NIC) in 40 CFR 63.1210(b) and (c) that were in effect prior to their vacatur on October 11, 2000. 

For more information regarding the streamlined permit modification procedure, see the RCRA Streamlined Permit Modification Fact Sheet (PDF, 368 KB). You also may refer to the June 19, 1998 Fast Track final rule preamble (63 FR 33782)
