As environmental managers are planning for 2018, one thing to plan for is Minnesota's update to Minn. R. 7011.2300 Standards of Performance for Stationary Internal Combustion Engines (IC engines). No later than January 31, 2018, owners and operators must not combust fuel in an IC engine with a sulfur dioxide content in excess of 0.0015 lb/MMBtu actual heat input unless an alternative sulfur dioxide emission limit has been proposed to the Minnesota Pollution Control Agency (MPCA). In order to propose a revised limit, a modeling demonstration and permit amendment application must be submitted.

If you have questions or need assistance establishing an alternative sulfur dioxide emission limit for an IC engine, reach out to Angie Wanger at (651) 275-9900 X-4.
