On April 7, 2017, Governor Edmund G. Brown Jr. terminated the drought State of Emergency for all counties except Fresno, Kings, Tulare, and Tuolumne following unprecedented water conservation and because key reservoirs are at over 100 percent of average.  Executive Order B-40-17 also rescinded Executive Orders B-26-14, B-28-14, B-29-15, and B-36-15, but maintained Executive Order B-37-16 in full force and effect. As a result of Executive Order B-40-17, two-engine water-well drilling rigs are no longer allowed to operate under the emergency provisions defined in the California Air Resources Board's Regulation for In-Use Off-Road Diesel Fueled Fleets (Off-Road Regulation) except for drought related emergency operations in Fresno, Kings, Tulare, and Tuolumne counties.

Two-engine water-well drilling rigs not being used only for drought-related emergency operations in Fresno, Kings, Tulare, and Tuolumne counties must meet all provisions of the Off-Road Regulation as of April 19, 2017 or be removed from operation in California.  This includes, but is not limited to, reporting and labeling requirements, and the ban on adding Tier 0 and Tier 1 vehicles.  Tier 0 vehicles were banned beginning January 1, 2014 for all fleets and Tier 1 vehicles were banned beginning January 1, 2014, for large and medium fleets, and January 1, 2016 for small fleets.  Tier 0 and Tier 1 two-engine water-well drilling rigs that were added to a fleet prior to the ban dates may remain in operation.

The documents below provide additional information and answers to frequently asked questions for both in-state and out-of-state water-well drilling rig vehicle owners who are operating or plan to operate in California during (and after) the State of Emergency.
