Phillips 66 Responds To Odor, Health Concerns of Meridian Refinery Cleanup Operations

Phillips 66 is a responsible, solution-oriented corporate citizen with a commitment to protecting human health and the environment. We are committed to ensuring the health and safety of our employees and the communities where we operate. Phillips 66 is working in partnership with Stephens County, under approval by the Oklahoma Department of Environmental Quality (DEQ), to clean up the former Duncan Refinery site. We voluntarily engaged in this cleanup effort to help deliver on the county’s vision to restore the site for future commercial and industrial purposes (see additional background below).

In early March 2018, Phillips 66 began cleanup of a portion of the former ponds at the property. Excavated material from the ponds was being mixed with Portland cement to stabilize it for transport to an off-site landfill. Intermittent odors were generated as a result of this process. Ongoing air monitoring at the worksite during this time indicated there was no health risk to workers at the site.

In response to concerns raised by some residents in nearby communities about the odors, we temporarily suspended our environmental remediation work at the Duncan Refinery site in late April out of an abundance of caution. We conducted air sampling at and around the site to collect data that was then analyzed by a certified lab. The analysis of the data reaffirmed our initial finding of no exceedances for chemicals of concern above EPA residential and OSHA standards. These results support that the odors pose no health risk to workers or to the community. We are working with the Oklahoma DEQ on our plan for future work and to minimize odors from pond cleanup activities. We will share the work plan with the community prior to resuming the pond remediation work later this summer.
