The intervenors have now called their next witness, James Carpenter, ITD's district engineer in Lewiston. Carpenter told attorney Natalie Havlina that when he attended a meeting in Kooskia about ExxonMobil's proposed megaloads, he was asked about traffic delays. "My response was that I was unaware of the 10-minute rule," he said. "We normally use 15 minutes, because that's what we use in construction for delays on our projects."
