According to reports, the NEW Cooperative facility in Duncombe, Iowa, increased its storage capacity to more than 2.5 million bushels in 2019, which reclassified it as a grain terminal elevator and triggered new emissions testing and dust limits.
The facility failed, however, to conduct the tests for more than a year, the DNR order said. Further, a compliance test in October 2021 showed that its new grain receiving system was emitting too much dust.
The facility was fined $6,000 for testing delays and the receiving system’s ongoing air quality violations. If, during the next testing, the equipment is not operating at maximum capacity, another test will be required before the end of the year, the DNR order said.
NEW Cooperative must also submit a plan to prevent future violations.
