EPA recently announced the opening of a public comment period on amendments to the Montalban Oil and Gas Operations (MOGO) injection well permit application in Pondera County. In this amendment, EPA modeled fluid migration over a 10,000-year period and aligned the aquifer exemption with the 10,000-year boundary. The modeling that EPA conducted shows the migration of fluids over a 10,000-year period won’t impact any US Drinking Water sources. Even though the regulations don’t require this level of analysis, we appreciate EPA’s increased scrutiny to address public concerns about aquifer impacts. The wells in Pondera County are not owned or controlled by Montana Renewables. Montana Renewables continues to analyze options for the safe and compliant management of additional non-hazardous wash water generated during renewable fuel production. These options are sustainable and science-based solutions that meet regulatory standards.
