From The Watch (Stephen Elliott):
For years, Idarado, which owns much of the land and water rights in the upper basins around Blue Lake, and the town of Telluride have argued — occasionally in a courtroom — over water. Now, the two entities are working together to achieve the mutual benefit the pipeline project will bring.
“This project is necessary because it’s a historic pipeline that existed many, many years ago, installed by miners. Since it’s very old, and it’s in very extreme conditions in terms of climate and geology, it has sprung a lot of leaks,” Telluride Environmental and Engineering Division Manager Karen Guglielmone said. “Over the last several years, we’ve been in a bit of a drought and [the amount of water stored in Blue Lake] has dropped by many feet. It has become quite obvious that additional water from the next drainage is important to maintaining that water storage.”[…]
The new pipeline connects Lewis Lake and Blue Lake. Lewis Lake is at a slightly higher elevation than Blue Lake, which means gravity can facilitate the transfer of water from the higher lake to the lower. The water then is transported to the Bridal Veil Falls power station and eventually to the Pandora water treatment plant.
The vast majority of the new pipe, made of high-density polypropylene, is being installed on the flatter stretches between the two lakes by EarthTech West out of Norwood. The work to install the flatter, simpler sections of pipe has been moving relatively quickly in comparison to the highly technical — and laborious — work required in order to install the 160-foot section of pipe on the cliff.
That’s the job of Access in Motion, the rope access experts, a company based in Telluride and led by owner/contractor Juju Jullien. The crew, a half-dozen (depending on the day) expert welders and machine specialists used to dangling off the sides of cliffs and buildings, work six, 10-hour days while living at the camp, with two days off in between.
“You have to drive for almost an hour, and the road is very dangerous. Driving it after 10 hours of work on a daily basis is not something you want everyone to do, so the camp made sense,” Jullien said. “You can have the best technicians, but they also have to be mountain people, and people that can get along. Six 10-hour days at that altitude with heavy equipment… it’s fun and we love it, but it’s not a job that you start by running, because that job will outrun you.”
That sentiment, combined with the highly technical work involved with securing the steel pipe to the cliff, means it’s hard for Jullien to estimate when they might be done, though a natural deadline would be the first snowfall, which is fast approaching at 12,000 feet. Guglielmone said initial estimates were that the project would take between six and 10 weeks and would be completed by mid-September. Jullien’s team was not able to visit the site for the first time until July 13 due to late spring snow and rain.
To secure the pipe to the cliff, Jullien’s team will drill nine one-inch stainless rods 15 inches into the rock, seal them and then weld them to the pipe. Each anchor will be stress-tested at 8,000 pounds for five minutes before the pipe can be secured.
“It’s all custom work, hard to predict, and all on ropes,” Jullien said. “Each support for the pipe, they’re all different because the rock is not a concrete wall. You cannot have one design that you multiply. It’s a slow process.”
More important than the speed necessary to install the pipe before the winter snows arrive is safety, Jullien said.
“There’s a notion of distance and isolation up here,” he said. “A little accident up here is serious. If you’re in town, you’re next to the medical center. That’s easy.”
“As far as natural hazards like lightning, rain, snow, and cold [go], even the sun is a hazard at 12,000 feet,” Jullien continued.
To manage safety concerns at the site, the Access in Motion and EarthTech West teams have a joint safety meeting each morning. Additionally, Jullien said, his team’s experience working in the oil and gas industry, where safety regulations are incredibly thorough, means they are taking even more safety precautions than prescribed by their own industry regulations.
“It’s a very industrial approach to safety,” Jullien said.
“You can’t have any failure. That’s what we’ve learned on the big fields.”
Because the project is mostly on Idarado’s land and is overseen by the Federal Energy Regulatory Commission, San Miguel County has limited oversight of the project. But, the county gave Idarado development permits and county staff visited the site.
“In general the county supports clean energy, and we think the hydroelectric plant does that,” county planning director Mike Rozycki said. “We look at it as an essential regional facility.”
At the site, reminders of the miners who once inhabited the basin below Blue Lake remain, in the form of dilapidated wooden structures and rusted pipes half-buried in the ground. Those miners are ever-present in the minds of those who now inhabit the flat, grassy campsite.
“We’re surrounded by historical flumes, and when we have to work around them and are not allowed to move them, we respect that because we understand how long they took to build,” Jullien said. “I love to see those old pieces of steel.”
Guglielmone has a more practical respect for the memory of the miners. She said that the fact that they built the pipe in the first place is reason enough to reconstruct it.
“Think about the miners living in those kinds of conditions. Would they really have built it if they didn’t believe that water was necessary in Blue Lake?” she asked. “They weren’t frivolous. They didn’t build infrastructure unless they felt strongly that they needed it.”
