Missouri proposing exemption for SI stationary engines.

January 29, 2016

The Missouri Department of Natural Resources (MDNR) accepted comments on preliminary rule development for 10 CSR 10-6.390, Control of NOx Emissions From Large Stationary Internal Combustion Engines according to a Trinity Consultants report. Comments were accepted through close of business on January 21, 2016. The proposed rulemaking is expected to be filed in the Missouri Register by March 15, 2016.MO DNR Logo

Missouri has proposed to add an exemption for spark ignition stationary internal combustion engines that is similar to that for compression ignition stationary internal combustion engines.

Specifically, spark ignition stationary internal combustion engines that began operation after September 30, 1997 and emit no more than 25 tons of nitrogen oxides (NOx) between May 1 and September 30 of the previous year could now be exempt from certain sections of the rule. It is clarified that exempt stationary internal combustion engines (both spark ignition and compression ignition) would be required to demonstrate compliance with the 25 ton limit using one of the following methods: certificates of conformity, stack tests, or engine manufacturer technical specification sheets.

Other methods, such as fuel usage calculations or other EPA documentation, would have to be approved by the director and the Environmental Protection Agency (EPA) and incorporated into the rule and Missouri’s State Implementation Plan (SIP) before being used to demonstrate compliance. In addition to the spark ignition exemption, the MDNR is also proposing to remove the startup, shutdown, or malfunction conditions in subsection (3)(F) per the EPA’s updated policy and the annual reporting requirement in section (4).

For more details, please see the draft rule text and the regulatory impact report on the Rules in Development page on the MDNR website. This page also provides instructions on submitting electronic and written comments.

Missouri is proposing SI engines that began operation after September 30, 1997 and emit no more than 25 tons of nitrogen oxides (NOx) between May 1 and September 30 of the previous year could be exempt from certain sections of its rule for large stationary IC engines. It is clarified that exempt stationary internal combustion engines (both spark ignition and compression ignition) would be required to demonstrate compliance with the 25 ton limit using one of the following methods: certificates of conformity, stack tests, or engine manufacturer technical specification sheets.
