**Citation:** 81 FR 3636  
**Type / status:** rulemaking / historical  
**Agency:** Pipeline and Hazardous Materials Safety Administration  
**Effective:** 2016-02-22  
**Published:** 2016-01-21

As required by the Moving Ahead for Progress in the 21st Century Act (MAP-21), the Pipeline and Hazardous Materials Safety Administration is amending the Hazardous Materials Regulations to adopt provisions contained in certain widely-used or long-standing special permits that have an established safety record. The adopted amendments are intended to provide wider access to the regulatory flexibility offered in special permits and eliminate the need for numerous renewal requests. The adopted amendments will also reduce paperwork burdens and facilitate commerce while maintaining an appropriate level of safety. PHMSA conducted an extensive analysis of all active special permits and codified, as appropriate, those special permits deemed suitable in this rulemaking.
