COMPLIANCE ORDER NO. 02_05_21R_001_4410001 FAILURE TO PROVIDE AN ADEQUATE SUPPLY OF PURE, WHOLESOME, HEALTHFUL, AND POTABLE WATER, & NONCOMPLIANCE WITH SOURCE CAPACITY REQUIREMENTS, & NONCOMPLIANCE WITH THE 2018 SANITARY SURVEY REPORT DEFICIENCY LIST

"The August 2020 CZU Lightning Complex Fires destroyed the Jamison SWTP and several other water system facilities. Following the loss of the Jamison SWTP, Big Basin WC currently has only one potable water source, Well 4, and cannot meet source capacity requirements. (pg 3)

Big Basin Water Company cannot meet the 10-year maximum day demand. (pg 4)

Big Basin WC does not have a second water source or a permanent interconnection to a nearby water system to ensure potable water supply in the event Well 4 fails or is out of service for maintenance, repairs, power outage, or other reasonably foreseeable events. Therefore, Big Basin WC cannot demonstrate the ability to provide a reliable and adequate supply of pure, wholesome, healthful, and potable water as required by CHSC, Section 116555 (a)(3). (pg 5)

Prior to the August 2020 CZU Lightning Complex fires, the State Water Board documented sanitary hazards and operational deficiencies found at Big Basin WC in the 2016 sanitary survey report (dated December 21, 2016), the 2018 sanitary survey report (dated January 10, 2019), and the 2020 surface water treatment plant evaluation (dated February 25, 2020). (pg 5)

Big Basin WC has a documented history of failing to administer preventative maintenance, emergency preparedness, and customer complaint programs. This lack of preparation and inadequate customer communication has contributed to Big Basin WC failing to reliably supply its customers with potable water during emergency events, including the 2019 PG&E Power Safety Shutoffs and the August 2020 CZU Lightning Complex Fire. These deficiencies constitute an ongoing threat of failure to provide a reliable and adequate supply of pure, wholesome, healthful, and potable water as equired by CHSC, Section 116555 (a)(3). (pg 5 - pg 6)

DETERMINATION

The State Water Board has determined that Big Basin WC cannot provide an adequate and reliable supply of water pursuant to CHSC, Section 116555 (a)(3) and has failed to comply with source capacity requirements pursuant to CCR, Title 22, Sections 64554(a)(2). (pg 6)
