BACKGROUND Heusinkveld Farms, LLP. April 28, 2025 On April 28, 2025, EPA conducted an NPDES Clean Water Act (CWA) compliance inspection at Heusinkveld Farms, LLP. (the Facility) in Spring Valley, Minnesota. This inspection was performed pursuant to Section 308(a) of the Federal Water Pollution Control Act, as amended. The Facility considers itself to be three sites. On the east side of County 5 to the north is the dairy site owned by Heusinkveld Farms LLP with a portion of the site siting on a parcel owned by Darla Heusinkveld. On the east side of County 5 to the south is the dry cow site is currently owned by Stephen Heusinkveld but is being purchased by the Operator. On the west side of County 5 is the heifer site owned by Nathan & Misty Heusinkveld. For the purposes of this inspection, the three sites will collectively be referred to as "the Facility". The Facility has approximately 460 dairy cows (dry or milking) and 200 heifers. The Facility is a medium animal feeding operation based on it having stabled or confined more than 200 mature dairy cows for 45 days or more in any 12-month period. Surface runoff from the Facility generally flows into the adjacent crop fields. The Facility's topography is hilly with steep slopes (see Attachment A). The Facility is bracketed to the north and south by National Hydrography Dataset identified unnamed intermittent tributaries of the South Branch Root River which have a confluence approximately 2,000 feet east of the Facility. These unnamed intermittent tributaries are mapped as flowing approximately 3.8 miles from their confluence east of the Facility to the perennial South Branch Root River. South Branch Root River is listed on the 303d impaired waterway list as being impaired for Murky Water. South Branch Root River flows to the Root River which flows to the Mississippi River, a Traditional Navigable Waterway. 2.

Yes Date NMP Submitted: 2023 Planner Name/Company: Fillmore County Soil and Water Conservation District Date that the NMP was last 2023 updated: Table 9: NPDES Permit Type of permit (General, individual) No NPDES Permit 2.2 Walkthrough of the Facility Prior to the inspection, Ben Atkinson contacted Mr. Nathan Heusinkveld (the Operator) and notified him that the United Stated Environmental Protection Agency (US EPA) intended to conduct a Clean Water Act compliance inspection at the Heusinkveld Farms facility on April 28th, 2025 and asked if facility personnel would be available to assist during the inspection. The Operator stated that he would be available. Mr. Atkinson informed the Operator of EPA's biosecurity procedures and asked if any additional biosecurity procedures were needed at the facility. The Operator stated that EPA's standard procedures were sufficient. On the date of the inspection, EPA inspectors Ben Atkinson and Cheryl Burdett (the Inspectors) along with Minnesota Pollution Control Agency Environmental Specialists Peter Kuisle and Brent Riess (MPCA), and Fillmore County Feedlot Officer Dallas Dornink (the County) arrived at the Facility at 9:39 AM. The Inspectors stopped and disinfected their vehicle's tires prior to driving onto the Facility. The Inspectors then parked, donned their disposable biosecurity boots, and approached the Operator. The Inspectors presented their credentials, confirmed that the location where they parked was acceptable, and asked if there was a space where the opening conference and interview portion of the inspection could be held. The Operator stated that their vehicle was parked in an acceptable location and led the Inspectors to the Office. The Inspectors explained that the inspection would be comprised of an interview portion to gather information about the Facility and a walkthrough of Facility. The Inspectors explained the Facility's right to claim information as Confidential Business Information (CBI) and asked if there was anything that would be considered CBI. The Operator stated he did not think anything would be CBI. The Inspectors explained that were a discharge to be observed, that samples may be collected and that split samples could be collected and preserved by EPA for the Facility to have analyzed if the Facility requested. The Inspectors then conducted the interview portion of the inspection. The Inspectors asked the Operator to clarify if the three adjoining sites were considered one operation. The Operator stated that he thought they were technically three operations with different legal ownership of the dairy site (owned by Heusinkveld Farms, LLP., dry cow site 7 Heusinkveld Farms, LLP. April 28, 2025 (owned by Stephen Heusinkveld but in the process of being purchased), and heifer site (owned by Nathan & Misty Heusinkveld). The Inspectors explained that under the Clean Water Act, two or more animal feeding operations that are under common ownership are considered to be a single animal feeding operation for the purposes of determining the number of animals at and operation if they adjoin each other or if they use a common area or system for the disposal of wastes. The Inspectors stated they would like to conduct the inspection assuming the three sites were one operation and address the question of whether the sites were a single operation following the inspection if needed. The Operator agreed to allowing access to inspect all three portions of the Facility. At approximately 10:30 AM, the interview portion of the inspection was completed, and the walk-through of the Facility began. The Inspectors began the walk-through at the Office and walked northeast to the southeast corner of the Machine Shed. The Inspectors then walked north between the Machine Shed Calf Barn 1 to the outdoor lot north of the Machine Shed. The Inspectors observed that the outdoor lot was partially denuded (photos 1-4). The Inspectors then walked back around the south end Calf Barn 1 and observed calf hutches between Calf Barn 1 and Calf Barn 2 (photo 5). The Inspectors walked north between Calf Barn 1 and Calf Barn 2 and observed the outdoor lot at the north end of Calf Barn 2. The Inspectors observed that the lot was denuded (photo 6). The Inspectors then walked east and observed a white pipe protruding from the hillslope northeast of Calf Barn 2 (photos 7 and 8). The Operator identified the pipe as coming from calf milk room in Calf Barn 2. The Inspectors walked east along the north side of the Feed Bunker and observed a flow path with white colored liquid originating from the pipe form Calf Barn 2 (photo 9). The Inspectors observed that there was no liquid in the flow path approximately 130 feet from the source (photo 10). The Inspectors walked east to the northeast corner of the Feed Bunker and observed holes and erosional flow paths in the soil at the base of the northeast corner of the Feed Bunker with a dark color liquid and staining present (photos 11-13). The Inspectors walked south and observed an access road between the Feed Bunker and the Big Pit (photo 15). The Inspectors walked southeast to the northeast corner of the Big Pit (photos 16 and 17).
