On Tuesday, October 6, multiple odor complaints were received from residents in the Anthem Subdivision, stating that there was a smell of sulfur or rotten eggs. After the odor complaints were received, there was an initial response taken by the North Metro Fire Rescue Department, Broomfield Emergency Management, Broomfield Public Health, Broomfield Public Works, and Extraction Oil and Gas. As a follow up to the initial response, Broomfield staff discussed the issue with Dan Bon with the Colorado Department of Public Health and Environment. Since the Colorado Air Monitoring Mobile Lab (CAMML) has been deployed since October 29, 2018, Broomfield staff inquired about hydrogen sulfide (H2S) levels during the time of the complaints. Dr. Bon stated that from 6-10 a.m. on November 6, 2018, there were H2S levels that were slightly above baseline. He went on say that this was considered unremarkable and would not have raised a concern. He only noted it because of the Broomfield inquiry. This level is not a violation of any applicable air standards. As a routine practice, Broomfield will utilize air monitoring partners to provide data associated with odor and air quality complaints.
