CalPortland Co announced Friday it has temporarily laid off 94 of the 130 workers at its Colton Cement Plant, citing a steep drop in demand for its products amid a near standstill in new Inland building.
"Cement shipments are off 60 per cent from the pre-recession demand," CalPortland President and CEO James Repman said by phone from the company’s Glendora headquarters.
The Colton Cement Plant opened in 1891 and is touted by CalPortland as the oldest operating cement plant west of the Rocky Mountains. Officials estimate it pumps US$183m into the local economy during full operations.
At its peak, it produced more than 800,000tpa of cement.
