ASCE/EWRI Call for Public Comment

ASCE and the EWRI Standards Council are calling for public comment on its Standard Practice for the Design and Operation of Precipitation Enhancement Projects. Precipitation enhancement projects or cloud seeding technology was developed to increase water supplies in drought-stricken areas. The technology is intended to increase the quantity and quality of water supplies by stimulating cloud growth so that rainwater is generated. The public comment period for the revised standard is from May 1 to June 15.

The standard provides water resources managers and others with information and references needed to make decisions on the use of cloud seeding to increase water supplies by defining when precipitation enhancement may be conducted. The standard also provides information on how to plan, conduct and evaluate such efforts. The public comment period is one of the final stages of ASCE’s consensus standards development process. The EWRI standards committee will review and address all comments submitted through the public ballot.

To obtain a copy of the public comment form and draft of the standard, send a written request accompanied by a $10 check or money order made payable to EWRI to the attention of Autumn Richter, EWRI Administrator, EWRI/ASCE, 1015 15th Street NW, Suite 600, Washington, D.C. 20005. Payment must accompany the request. EWRI will not accept facsimile requests.
