Rifle Citizen TelegramA state oil and gas regulator expressed alarm over the way topsoil and water have been handled at this pipeline construction site in Battlement Mesa. By Alex Zorn, Rifle Citizen Telegram Summit Midstream, the company installing pipeline in Battlement Mesa, has engaged in “improper practices” regarding soil and stormwater handling, according to a report sent to Garfield County by Colorado Oil and Gas Conservation Commission environmental manager Greg Deranleau. Deranleau recommended that the county refer the sites to the Colorado Water Quality Control Division for review and inspection, but the Colorado Department of Public Health and Environment said that it did not have the resources to investigate the matter, according to Garfield County oil and gas liaison Kirby Wynn. Wynn said Tuesday that he and the county are already directly working with Summit Midstream to address Deranleau’s concerns about site preparation and topsoil management.
