Greka's Cat Canyon operation has been listed by the Santa Barbara County Air Pollution Control District as a "significant risk facility". Three Health Risk Assessments have been performed, in 1991, 1994, and 1998, all before Greka acquired the facilities, and they showed steadily decreasing cancer and non-cancer risks. From 1991 to 1998, the cancer risk had declined from 63 in a million to 12 in a million.SBCAPCD, 2009
