This twenty-year old farm consisted of several barns each of which was equipped with two 242-gallon rinse tanks that were used to flush the pit area under the barns twice daily. The manure pits discharged to a 5.5 million gallon lagoon. The lagoon was not meeting the discharge permit levels. Examination determined that there was no presence of biological activity in the lagoon and the solids build-up on the lagoon surface was at a critical level. H2S odor was so severe that plant employees were often unable to perform their duties because of respiratory problems and eye irritation.
Located nine miles north of Ipswich, SD, this hog operation utilizes multiple barns and maintains approximately 10,000 hogs on site. The hog operation manager, Larry Wipf, is an experienced, well‐seasoned operator. The barns operate on a pull–plug manure collection system with all the hog waste draining to a common pumping station approximately 100 feet north of the 750,000 gallon concrete holding pit. The level of waste in this pit is maintained at a pre‐set level and as that level is exceeded, a pumping station approximately 30 feet to the west of the pit, automatically pumps the excess to the lagoon system. The lagoon system consists of two large lagoons set‐ up in sequence. The primary lagoon effluent is gravity fed to the second lagoon via an installed culvert system. The secondary lagoon is pumped yearly and the effluent is land applied by a pivot irrigation system.
