CASPER, Wyo. (AP) — The operator of the Salt Creek oil field will offer housing for some Natrona County residents as crews continue to search for the source of a gas leak.

The Casper-Natrona County Health Department says Fleur de Lis Energy will provide housing in Casper for people who do not feel comfortable staying in Midwest.

Oil field crews in still have not found the source of a chemical odor first noticed on May 25 that forced the closure of a nearby school.

Health Department official Audrey Gray says tests performed May 26 and 30 detected volatile organic compounds and showed higher than normal levels of carbon dioxide. She says the local department is reaching out to state and federal partners for help interpreting those readings.
