New Hampshire Culvert Certification

The UNH T2 Center offers a full day Culvert Maintainer Certification Training class held in various locations  throughout New Hampshire. The course covers the basics of the NH culvert legislation that became effective December 21st, 2013. These rules were adapted in compliance with RSA 482-A:3, XVII - XIX. The course will cover these basics:

  • Certification Legislation
  • Certification Requirements
  • Process
  • Culvert Criteria
  • Responsibilities
  • Staying Certified
 **It is important to note that although the culvert training is through the Technology Transfer Center, certification is provided by the NHDES.
