Unocal Corp. will close its 52-acre Brea plant by 1991, cutting more than 130 jobs and consolidating operations at its West Sacramento facility because of a downturn in the chemical fertilizer market, company officials reported. The company has operated a chemical plant in the foothill city since 1954, producing such chemicals as ammonia and urea, which are sold wholesale to fertilizer dealers throughout the West and later purchased in bulk by farmers. None of the estimated 136 operations, maintenance or support personnel will be laid off until 1989, and the final layoffs will happen in 1991.
