MurCal Granted Final Certification for the SNGEC System
July 2, 2015
On June 29, 2015 MurCal was granted Final Certification by the San Joaquin Valley Air Pollution Control District under District Rule 4702 (Internal Combustion Engines) for the Stationary Natural Gas Emission Compliance (SNGEC) System. Rule 4702 requires that an agricultural, rich-burn, spark-ignited IC engine must reduce exhaust emission levels to less than or equal to all of the following limits, corrected to 15% exhaust oxygen content: 90 ppmvd-NOx, 2,000 ppmvd-CO, and 250 ppmvd-VOC.
MurCal is in a unique position in the market. After a two year certification process, starting with the conditional certification in 2013 and culminating with the current final certification, MurCal became the only applicant to successfully complete the District’s certification process.
