Y. Rubber, Miscellaneous Plastic Products, and Miscellaneous Manufacturing Industries

1. Authorized Stormwater Discharges

The requirements in Sector Y apply to stormwater discharges associated with industrial activity from rubber, miscellaneous plastic products, and miscellaneous manufacturing facilities as identified by the industrial activity code specified in Table 5 of Appendix D.

2. Industrial Activities Authorized by Sector Y

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

a. Manufacturing of tires and inner tubes.

b. Rubber and plastic footwear.

c. Gaskets, packing and sealing devices, and rubber hose and belting.

d. Fabricated rubber products.

e. Manufacturing of miscellaneous plastics products.

f. Musical instruments.

g. Dolls, toys, games, and sporting and athletic goods.

h. Pens, pencils, and other artists’ materials.

i. Costume jewelry, costume novelties, buttons, pins, and needles.

j. Miscellaneous notions, except precious metal.

3. Limitation on Authorization (No Additional Limitations)

4. Sector-Specific Definitions (No Additional Definitions)

5. Stormwater Controls

a. Employee Training (No additional requirements).

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

c. Good Housekeeping (No additional requirements).

d. Inspections (No additional requirements).

e. Preventive Maintenance.

1. The Permittee shall describe and implement specific controls to minimize contact of zinc with stormwater discharges by:

a. Using chemicals purchased in pre-weighed, sealed polyethylene bags.

b. Storing in-use materials in sealable containers.

c. Ensuring an airspace between the container and the cover to minimize “puffing” losses when the container is opened.

d. Using automatic dispensing and weighing equipment.

e. Replacing or repairing improperly operating dust collectors or baghouses.

2. The Permittee shall describe and implement specific controls to minimize contact of plastic resin pellets with stormwater discharges.

f. Spills and Leaks (No additional requirements).

g. Management of Runoff (No additional requirements).

h. Other Industry Specific Stormwater Controls (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 (No additional requirements).

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

c. Potential Pollutant Sources.

The Permittee shall review the use of zinc at the facility and the possible pathways through which zinc may be discharged into stormwater. The Permittee shall list the materials and activities at the facility that are sources of zinc.

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 Y-1, below:

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

Subsector Parameter Benchmark Values
Y1 Fabricated Rubber Products Zinc, Total (as Zn) 0.234 mg/L 1
Lead, Total (as Pb) 0.164 mg/L 1
Solids, Total Suspended (TSS) 100 mg/L 2
Y2 Plastic Products Solids, Total Suspended (TSS) 100 mg/L 2

1The benchmark values of some metals are influenced by water hardness. For these parameters, the Permittee may determine the hardness of the stormwater discharges to identify the applicable ‘hardness range’ for determining their benchmark value. See Table 4 of Appendix B for hardness dependent benchmark values in accordance with Minn. R. 7050.0222 and Minn. R. 7052.0100.
2If 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 Y industrial facilities are authorized to use designed infiltration devices or industrial stormwater ponds for stormwater management.
