Pending before the Court are multiple motions for summary judgment including Defendants Northwest Fiber, LLC d/b/a Ziply Fiber; Ziply Fiber of Idaho, LLC; Ziply Fiber Northwest, LLC’s (collectively Ziply) Motion for Summary Judgment (Dkt. 93); Defendant Avista Corporation’s (Avista) Motion for Summary Judgment (Dkt. 94); Defendant HHS Construction, LLC’s (HHS Construction) Motion for Summary Judgment against Defendant PG Engineering Management Corp. (PG Engineering) (Dkt. 95); and Plaintiffs’ Motion for Partial Summary Judgment (Dkt. 96). For the following reasons, the Court grants in part and denies in part the motions. I. BACKGROUND A. Relationship of the Defendants This action arises from an explosion that occurred on October 28, 2021, in Rathdrum, Idaho, while Defendants were installing the infrastructure for fiber optic cable in a residential neighborhood (Dkt. 5-1 ¶ 40; Dkt. 112-2 ¶ 2). Ziply obtained a Right-of-Way Encroachment Inspection Permit from the City of Rathdrum (Rathdrum Permit) to install the infrastructure (the Ziply project) (Dkt. 101 at 2, 4). At issue is Ziply’s liability and the liability of various subcontractors involved in the Ziply project for the explosion. After Ziply obtained the Rathdrum Permit, it contracted with HHS Construction to install the infrastructure in multiple locations, including in the neighborhood where Plaintiffs Chris Lee and Sara Lee (the Lees) and their minor children, R.L. and T.L., resided (Dkt. 108 at 17 n.10). HHS Construction, in turn, contracted with PG Engineering to conduct the underground boring

work on the Ziply project (Dkt. 109 at 6; Dkt. 120 at 3–4). PG Engineering then contracted with Defendant Mastod’s Consulting Services, Inc. (Mastod’s) to perform horizontal directional drilling (Dkt. 109 at 6). Mastod’s engaged Diego Vasquez and his crew to conduct the drilling (id.). PG Engineering was responsible for on-site supervision during the boring work, although its representative was with a different crew when Vasquez began work near the Lee residence on the day of the explosion (Dkt. 93-2 ¶ 16; Dkt. 98-1 at 283). It is undisputed that before the digging began, the gas line locations had been properly marked (Dkt. 94-1 ¶ 13; Dkt. 93-1 at 18:25–19:17). B. The Incident On the morning of October 28, 2021, while engaging in horizontal directional drilling in in front of the Lee residence, Vasquez’s crew struck an underground natural gas line, causing a

significant gas leak (Dkt. 94-1 ¶ 8). At 10:04 a.m., a member of the work crew informed the Lees, who were in the residence, of the leak (id. ¶ 9). The boring crew then tried to cover the line with dirt and rocks (Dkt. 5-1 ¶ 18). At 10:08 a.m., the Lees observed a plume of natural gas and dirt shoot upward out of the line, and at 10:09 a.m., they evacuated the house and called 911 from their backyard (Dkt. 94-1 ¶¶ 11–12). C. Avista’s Initial Response About the same time, Avista, which is the natural gas provider in the area, was notified about the leak. At approximately 10:05 a.m., Ryan Sager, an Avista employee, received a call reporting the leak (Dkt. 94-1 ¶ 14). Sager alerted Jason Stevens, another Avista employee and a journeyman gas serviceman, who had over twenty years’ experience (id. ¶ 19), and Stevens immediately began driving to the scene (id. ¶ 21). Stevens was formally dispatched at approximately 10:20 a.m. and arrived on site around 10:40 a.m. (id. ¶ 25). Avista’s dispatch classified the incident as a priority 1, code 9, indicating blowing or escaping gas (id. ¶¶ 23–24).

Once on the scene, Stevens assumed the role of incident commander; coordinated with the fire department personnel who were on the scene; cleared excavators from the area; and investigated the source of the leak (id. ¶¶ 27–30). He confirmed that the excavators had not properly potholed the gas line; called dispatch to request additional crew and emergency locates; and shut off the gas to the Lee residence and removed the electric meter (id. ¶¶ 30–32). During the incident, the Lees requested to enter the home to retrieve personal items (Dkt. 5- 1 ¶ 20). Stevens escorted them in the residence while actively monitoring gas levels with a handheld combustible gas indicator (CGI); during this time, he detected readings of 0–60 ppm on the main level and 0–600 ppm on the upper level (Dkt. 94-1 ¶ 36–37). After the Lees exited their residence, Avista personnel continued to monitor the Lee

residence and the surrounding area (Dkt. 101 at 9). Dan Holden, an Avista employee, began bar holing1 approximately six inches from the foundation of the residence using a CGI to detect subsurface gas (Dkt. 94-1 ¶¶ 50–51). These readings showed 0 percent LEL outdoors (id. ¶ 51). Avista personnel also ventilated the residence by leaving doors open and continued to monitor gas both inside and outside the affected homes (id. ¶¶ 44–47, 50–51). Later, while the gas flow was still off and the power to the home was disconnected, the Lees requested to return to the residence again (id. ¶ 52). At approximately 12:39 p.m., Stevens

1 Bar holing is a method of monitoring for gas in the ground using perforated stakes placed in the ground that test gas levels with a CGI (Dkt. 94-1 ¶ 50). re-entered the home with the Lees, conducted a floor-by-floor sweep with his CGI, and detected 0 percent LEL throughout the home, including the garage (id. ¶ 53–56). He then proceeded to reinstall the electric meter (id. ¶ 57). D. The Explosion

Shortly after Stevens restored the power to the Lee residence, Mr. Lee reported hearing a popping noise from the furnace. Stevens initially turned off the breaker but then turned it back on (Dkt. 94-1 ¶ 60). As he entered the house from the garage, a fireball erupted above his head (id. ¶ 62). At that time, Mrs. Lee was upstairs, and Mr. Lee and Stevens were in the garage (id. ¶ 63). Both men evacuated through the garage, and Mrs. Lee was later rescued from a second-story window as the fire spread through the Lee residence (id. ¶¶ 66, 68). Mrs. Lee was assessed following the explosion and did not suffer physical injuries (Dkt. 94-2 at 7). Mr. Lee suffered second-degree burns to his arms and neck, and Stevens sustained a first-degree burn on the back of his neck (id.). At the time of the explosion, the Lees’ minor children, R.L. and T.L., were at school, which is located approximately 645 feet from the Lee

residence (Dkt. 108 at 17 n.10). While R.L.
