U. Food and Kindred Products

1. Authorized Stormwater Discharges

The requirements in Sector U apply to stormwater discharges associated with industrial activity from food and kindred products facilities as specified by the industrial activity code specified in Table 5 of Appendix D.

2. Industrial Activities Authorized by Sector U

Permittees under Sector U are primarily engaged in the following types of activities:

a. Meat products.

b. Dairy products.

c. Canned, frozen, and preserved fruits, vegetables, and food specialties.

d. Grain mill products.

e. Bakery products.

f. Sugar and confectionery products.

g. Fats and oils.

h. Beverages.

i. Miscellaneous food preparations and kindred products.

j. Tobacco products.

3. Limitations on Authorization

a. The following discharges are not authorized by this permit:

1. Stormwater discharges co-mingled with wastewaters or sources of nonstormwater, other than those listed under Part II of this permit, including those from industrial plant yards; material handling sites; refuse sites; sites used for application or disposal of process wastewaters; sites used for storage and maintenance of material handling equipment; sites used for residential wastewater treatment, storage, or disposal; shipping and receiving areas; manufacturing buildings; and storage areas for raw material and intermediate and finished products. This includes areas where industrial activity has taken place in the past and significant materials remain. Material handling activities include the storage, loading and unloading, transportation, or conveyance of any raw material, intermediate product, finished product, by-product, or waste product.

2. Discharges subject to operations and process requirements of Part II, which include discharges containing boiler blowdown, cooling tower overflow and blowdown, ammonia refrigeration purging, and vehicle washing and clean-out operations.

b. Wastewater generated from these areas shall be treated at the facility’s wastewater treatment facility in accordance with the facility’s NPDES permit, or by discharge to a publicly owned treatment works (POTW), as authorized by the POTW. Stormwater discharges from these areas are authorized where no mixing of stormwater with wastewater or non-stormwater occurs, and where these areas do not at any time generate wastewater or non-stormwater.

4. Sector-Specific Definitions (No Additional Definitions)

5. Stormwater Controls

a. Employee Training.

The Permittee shall include the following activities as appropriate:

1. Used oil and spent solvent management.

2. Segregation of organic materials, raw materials, and products from contact with stormwater and precipitation.

3. Pest control.

b. Erosion and Sedimentation Controls (No additional requirements).

c. Good Housekeeping (No additional requirements).

d. Inspections.

1. The Permittee shall inspect the following areas where the potential for exposure to stormwater exists:

a. Waste management units.

b. Vents and stacks associated with industrial activities.

c. Spoiled product and broken product container holding areas.

d. Animal holding pens.

e. Staging areas.

f. Air pollution control equipment.

2. In addition to the inspection requirements outlined in Part III.F, the Permittee shall ensure that a total of two (2) of the required monthly inspections occur during runoff events, with at least one being performed during snow melt. Each inspection shall include a visual assessment of the runoff to identify any visible sheens or films that indicate the presence of oil or grease in the discharge. If sheens are present in stormwater discharges, corrective actions to prevent sheen shall be implemented and documented in the SWPPP.

The Permittee is only required to conduct visual inspections of runoff originating from, or passing through, areas of industrial activity and/or significant materials. Any runoff that does not contact industrial activity and/or significant materials (e.g. office buildings, employee parking lots, natural areas, etc) is not required to be inspected.

e. Preventive Maintenance (No additional requirements).

f. Spills and Leaks (No additional requirements).

g. Management of Runoff (No additional requirements).

h. Other Industry Specific Stormwater Control Measures (No additional requirements).

6. SWPPP Requirements

In addition to the requirements of Part IV, the Permittee shall also comply with the following:

a. Facility Map.

The Permittee shall identify the locations of the following activities if they are exposed to stormwater:

1. Vents and stacks from cooking, drying, and similar operations.

2. Dry product vacuum transfer lines.

3. Animal holding pens.

4. Spoiled product and broken product container storage areas.

b. Inventory of Exposed Materials (No additional requirements).

c. Potential Pollutant Sources.

The Permittee shall describe, in addition to food and kindred products processing-related industrial activities, application and storage of pest control chemicals (e.g. rodenticides, insecticides, fungicides) used on plant grounds.

d. Description of Stormwater Controls (No additional requirements).

7. Monitoring and Reporting Requirements In accordance with the monitoring requirements of Part V, the Permittee shall monitor the applicable parameters in Table U-1, below:

Sector-Specific Benchmark Values and Effluent Limitations: Sector - U: Discharges may be subject to requirements for more than one sector or subsector.
Link to this table

Subsector Parameter Benchmark Values
U1 Grain Mill Products Solids, Total Suspended (TSS) 100 mg/L 1
U2 Fats and Oils Products Solids, Total Suspended (TSS) 100 mg/L 1
BOD, Carbonaceous 05 Day (20 Deg C) 25 mg/L
COD (Chemical Oxygen Demand) 120 mg/L
Nitrogen, Ammonia, Total (as N) 2.8 mg/L
U3 Food and Tobacco Products, Food Preparation Facilities Solids, Total Suspended (TSS) 100 mg/L 1
BOD, Carbonaceous 05 Day (20 Deg C) 25 mg/L
COD (Chemical Oxygen Demand) 120 mg/L
Nitrogen, Ammonia, Total (as N) 2.8 mg/L
Phosphorus, Total (as P) 1.0 mg/L

1If the Permittee is required to comply with Appendix A, part F.1, the benchmark value for Solids, Total Suspended (TSS) is 65 mg/L, instead of 100 mg/L.

8. Use of Infiltration Devices and/or Industrial Stormwater Ponds for Stormwater Treatment and Disposal

Sector U industrial facilities are authorized to use designed infiltration devices or industrial stormwater ponds for stormwater management.
