Olsen Canyon Properties filed an application for a surface-mining permit in early November. Many of the application’s pages are marked “draft,” indicating that changes can be expected.
In obtaining a copy of the 52-page application and reading through it, some of what was presented on behalf of Olsen at November’s Temescal Valley Municipal Advisory Council meeting needs additional explanation:
- The MAC audience was told the mine would operate for 70 years. The application seeks a 100-year permit.
- We were told Olsen Canyon had no source for the massive amount of recycled water it will need in controlling dust. The application states Temescal Valley Water District will furnish the water. A group of residents attending the October and November water board meetings were told by district officials that they have refused Olsen’s request because the district does not have a sufficient amount of recycled water to sell to the mine.
- The mine will reach a depth of 450 feet; not the 400 feet earlier stated.
- While the audience was told residents would be warned prior to blasting, the application describes the blasting as being used “on a weekly basis … conducted on weekdays between the hours of 10 a.m. and 3 p.m.”
- Hours for the mining and rock crushing operations will be 6 a.m. to 4 p.m. Monday through Friday, and 7 a.m. to 2 p.m. Saturday — from Oct. 2 to June 1 of each year. BUT – from June 1 to Oct. 1, to avoid peak-time electrical use, the hours will be midnight to 11 a.m. Monday through Saturday.
- Clarification on truck trips – the mine will generate 301 loads a day for a total of 602 trips.
- The ready-mix concrete and asphalt batch plants will contain 60-foot tall silos. The number of silos is unclear.
