Document Description
Notice of Exemption for statutorily exempt project, pursuant to CEQA Guidelines Section 15269(a) for Emergency Projects. The Los Angeles Department of Water and Power (LADWP) has obtained an interim variance from enforcement of Great Basin Unified Air Pollution Control District (GBUAPCD) Board Order 160413-01, GBUAPCD Rule 433, and Notice to Comply No. 2002 for dust control area (DCA) T13-1 (includes T13-1 and T13-1 Addition, operated as one unit, hereafter T13-1) and T5-3. This Board Order and Rule require LADWP to implement Best Available Control Measures (BACM) to achieve dust control performance criteria in designated DCAs during the dust season. Between August 19, 2023, and August 22, 2023, Tropical Storm Hilary (Hilary) brought flash flooding to the Owens Lake area. In anticipation of Hilary, the Governor of California declared an emergency along with the counties of Inyo, Los
Angeles, Imperial, Riverside, and San Bernardino. This natural disaster resulted in extreme flash flooding that impacted the eastern portion of the Centennial Wash Alluvial fan as well as the Owens Lakebed, including the Variance Areas discussed below.
DCAs T13-1 and T5-3 are included in this variance (Variance Areas). Large areas of these DCAs and their associated infrastructure (i.e. irrigation laterals, whipline, partitions/ berms, and risers) were damaged or buried with sediment by the Hilary event. LADWP will rehabilitate the damaged DCA’s by removing deposited sediment and grading; repairing and unburying irrigation laterals and risers; repairing and constructing partitions/ berms; repairing, realigning, and installing whiplines; and flushing irrigation laterals and whiplines. Ground disturbance activities will be monitored by qualified tribal monitors as a precautionary measure.

Notice of Exemption
Exempt Status
Declared Emergency
Type, Section or Code
Sec. 21080(b)(3); 15269(a)
Reasons for Exemption
Section 15269(a) states that “Projects to maintain, repair, restore, demolish, or replace property or facilities damaged or destroyed as a result of a disaster in a disaster-stricken area in which a state of emergency has been proclaimed by the Governor pursuant to the California Emergency Services Act, commencing with Section 8550 of the Government Code. This includes projects that will remove, destroy, or significantly alter an historical resource when that resource represents an imminent threat to the public of bodily harm or of damage to adjacent property or when the project has received a determination by the State Office of Historic Preservation pursuant to Section 5028(b) of Public Resources Code.” A State of Emergency was declared on August 19, 2023, in response to Tropical Storm Hillary in Inyo County that caused damage to roads and public infrastructure in and around Owens Lake. The proposed project meets the requirements of this exemption; therefore, no further CEQA review is required.
