EPA Region 5 lead inspector confirmed the following facility information: Kuhlman Corporation is a wholly owned subsidiary of Gerken Companies and was acquired in 2021. Kuhlman Corporation Yard #1 (Kuhlman) is a ready-mix plant that produces ready mix concrete for residential, highway and commercial use. They have approximately 15 trucks, bulk piles of sand and aggregates at the facility. Midwest Terminals, which is not part of Gerken Companies, owns the area along the Maumee River, the Bulk Storage Barn and another building south-east of the Kuhlman maintenance garage. Joe Isabell stated that Midwest terminals owns the outfalls. Mr. Isabell stated that the aggregate piles are natural sand from Michigan and that all the materials, except cement powder, is transported in by truck. The facility uses the aggregate to produce ready mix concrete for commercial, residential, and highway use. David Benecke applied for coverage under General Permit OHR000007 for Kuhlman Corporation Yard #1 on September 1, 2022. On November 30, 2022, the Ohio Environmental Protection Agency approved coverage for Kuhlman Yard #1, effective December 1, 2022, and expiring May 31, 2027.

SECTION II - OBSERVATIONS
Location: Office document review Observation #: WJ1-OB-001
Date: April 10, 2025
Weather: Cloudy with recent rain
EPA obtained a copy of the Storm Water Pollution Plan (SWPPP) on site. It was dated March 2021. See Appendix 3. In the SWPP provided to EPA, a drawing of the facility was included and highlighted with green marker to show approximate property locations and illustrates how the Kuhlman property is located between the Midwest Terminal property and the Anderson property. Mr. Isabell's says the facility maintenance staff does the visual inspections monthly on the inlet filters. Mr. Isabel also stated the facility is swept weekly on Tuesdays and Thursdays.
Location: Storage bunkers Observation #: WJ1-OB-002
Date: April 10, 2025
Weather: Cloudy with recent rain
During the inspection, EPA observed runoff from storage bunkers. The runoff was flowing to the storm drain inlet in the photograph.

Location: Area on east side of storage piles
Observation #: WJ1-OB-003
Date: April 10, 2025
Weather: Cloudy with recent rain
During the inspection, EPA observed an area to the east of the storage piles where storm water can flow through a conveyance to the edge of the property leading to the Maumee River.

EPA observed a manhole near the facility's lab that was partially surrounded by sandbags. Loose material was seen on the downslope edges of the sandbags and one of the sandbags had ripped open. Mr. Benecke noted that the staff tests new concrete mixes inside the lab and wash it out upslope of the bags and then it drains to the storm sewer.

SECTION III - RECORDS REVIEW
Records may not be in sequential order
Record: Storm Water Pollution Prevention Plan
Ref #: WJ1-RR-001
Reviewed By: William Jones
AOC: Yes Reviewed Date: April 10, 2025
The SWPPP was dated from before the issuance of the current permit cycle. Facility staff said that they were in the middle of updating it. One issue the facility stated was where they facility should sample, since the facility does not own the outfalls. Mr. Benecke also said that there is historic contamination under the property. so the facility cannot dig down more than two feet unless they store and test the soil and water to see how to dispose of it. It is a risk mitigation plan. The facility spoke with Lashana Weeks, City of Toledo, in the past and said she is checking on the sampling locations. EPA reviewed the sampling reports since April 2020. David Benecke said the last time they had access to the outfalls was in 2022 or early 2023. The City of Toledo inspected the site about a year ago.
The following sections of the SWPPP were not reflective of current conditions: 1. References through the SWPPP appear to be from the 2017 NPDES Permit. - Section 1.6 described the site as receiving rock salt, oats, canola pellets, cotton seed, distillers' grain, urea, potash and other fertilizers, and alumnium briquettes. This did not match with what facility staff stated about the site during the inspection, nor what was observed during the inspection. - Section 1.8 contained an inaccurate map, due to the site sale. - Section 2.0 describes a salt pile that was not observed during the inspection or noted on the site maps. - Section 2.2 and 2.4 lists areas no longer owned by Kuhlman. Other sections in the permit following this appear to be based on the 2017 permit. - Most of the appendices are missing content. The maps are not up to date.

SECTION IV - SAMPLING ACTIVITIES AND ANALYTICAL RESULTS No sampling was conducted.
SECTION V - AREAS OF CONCERN
See below for areas of concern related to the current industrial storm water General Permit OHR000007:
Part 2.1.2.1 requires "You shall minimize exposure of manufacturing processing, and material storage areas (including loading and unloading, storage, disposal, cleaning, maintenance and fueling operations) to rain, snow snowmelt, and runoff by either relocating these industrial materials and activities inside or protecting them with storm resistant coverings (although significant enlargement of impervious surface area is not recommended)..."
There are material storage areas where the exposure of materials is not minimized. See photographs.
Section 2.1.2.3 of the permit requires Maintenance. "You shall maintain all control measures that are used to achieve the control measures/best management practices (BMPs) and numeric effluent limits required by this permit in effective operating condition. Nonstructural control measures shall also be diligently maintained (e.g., spill response supplies available, personnel appropriately trained). If you find that your control measures need to be replaced or repaired, you shall make the necessary repairs or modifications as expeditiously as practicable."
EPA noted inlet filters were not cleaned, nor was housekeeping maintained.
Section 2.1.2.10 "You shall eliminate non-stormwater discharges not authorized by an NPDES permit"
Pursuant to Section 1.1.3 of the General Permit, non-stormwater discharges, do not include releases of test concrete from the facility lab near the sandbagged storm drain inlet.
Part 5. "If you prepared a SWPPP for coverage under a previous NPDES permit, you shall review and update the SWPPP to implement all provision of this permit within 180 days after the effective date of this permit." The permit was effective December 1, 2022.
SWPPP is dated March 2021. There is an outfall by the stockpile yard with raw materials that does not appear to be included.
Part 6.1.1 of OHR000007 requires "Applicable monitoring requirements apply to each outfall...For monitoring purposes, an outfall can include a discrete conveyance (i.e. pipe, ditch, channel, tunnel or conduit) or a location where sheet flow leaves your facility's property..."
Sampling is not being done at the outfalls. The facility is unclear where sampling should be done, since the dock area belongs to Midwest Terminal. The General Permit defines what an outfall can include and describes conducting representative monitoring.
See above observations in section II and III related to the Areas of Concern.

SECTION VI - CLOSING CONFERENCE AND FOLLOW UP
Closing Conference
The EPA REGION 5 Lead Inspector held a closing conference with Facility personnel on April 10, 2025, for the inspection. During the closing conference, EPA REGION 5 Lead Inspector discussed the observations and Areas of Concern identified during the inspection. Observations and Areas of Concern have not yet been evaluated for a formal compliance determination.
William Jones, along with Jeremy Leggett, Joe Isabell, and David Benecke, were present for the closing conference. Mr. Jones shared that the observations and Areas of Concern were preliminary. Mr. Jones confirmed that no information gathered was considered Confidential Business Information. During the closing conference, David Benecke stated the facility has an issue with dust blowing from Midwest Terminal. Mr. Jones then relayed the following preliminary observations to the facility representatives:
SWPPP and map are out of date; Sampling is not being done at the outfalls; Inlet filters were not being maintained; Outfall, by the stockpile yard, with raw materials; Housekeeping concerns with grain along the dock area; Discharge points that are not included in the SWPPP; Storm drain with ripped sandbags, and close proximity to where the lab dumps out test concrete; and Housekeeping issues with dust throughout the facility.
Follow Up
No information was requested by the inspector after the inspection.
