Handbook

The Low Impact Hydropower Certification Handbook is reviewed annually. The Handbook is currently in its Second Edition, Revision 2.04 – April 1, 2020 (a redline version showing recent changes is here). The Handbook is edited and updated as needed with input from staff, governance, and with public comment in the case of proposed programmatic changes.

See the program eligibility page for information on the proposal to expand eligibility for newer construction.
