CDPHE Releases Air Quality Report for
Woolley-Sosa and Erie Champlin Sites
The Town of Erie would like to make the public aware of a report issued this week by the CDPHE titled: “Health Risk Evaluation from Inhalation of VOCs in Ambient Air Near Woolley-Sosa and Erie Champlin Oil and Gas Sites.”
Summary: The Oil and Gas Health Information and Response (OGHIR) Program at the Colorado Department of Public Health and Environment (CDPHE) received a large volume of calls since December 2016 from residents in multiple neighborhoods in Erie reporting odor and health concerns possibly related to emissions from Woolley-Sosa and Erie Champlin sites.
In response, OGHIR deployed the Colorado Air Monitoring Mobile Laboratory (CAMML) on March 7-8 and March 20-23, to measure volatile organic compounds (VOCs) in the air where residents have reported health symptoms and odors.
The evaluation indicated that all air concentrations of individual and combined VOCs were below non-cancer health-based reference values. Cancer risks estimates for benzene, ethylbenzene, and the two VOCs combined were less than one in one hundred thousand, which is generally considered to be within the acceptable risk range.
Using currently available measurement technology and risk assessment methods, OGHIR is unable to document conditions that suggest an ongoing health hazard at this time.
