V. Textile Mills, Apparel, and Other Fabric Products Manufacturing

1. Authorized Stormwater Discharges

The requirements in Sector V apply to stormwater discharges associated with industrial activity from textile mills, apparel, and other fabric product manufacturing as identified by the industrial activity code specified in Table 5 of Appendix D.

2. Industrial Activities Authorized by Sector V

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

a. Textile mill product preparation, including preparation of fiber and subsequent manufacturing of yarn, thread, braids, twine, and cordage.

b. The manufacture of broadwoven fabrics, narrow-woven fabrics, knit fabrics, and carpets and rugs from yarn.

c. Processes involved in the dyeing and finishing of fibers, yarn fabrics, and knit apparel.

d. Apparel and other finished products made from fabric and similar materials, integrated manufacturing of knit apparel and other finished articles of yarn, manufacturing of felt goods (e.g. wool), lace goods, non-woven fabrics, miscellaneous textiles, and other apparel products.

e. Leather and leather products, except leather tanning and finishing.

3. Limitations on Authorization

Discharges of wastewater (e.g. wastewater resulting from wet processing or from any processes relating to the production process), reused or recycled water, and waters used in cooling towers are not authorized under this permit.

4. Sector-Specific Definitions (No Additional Definitions)

5. Stormwater Controls

a. Employee Training.

As part of the employee training program, the Permittee shall address the following activities:

1. Use of reused and recycled waters.

2. Solvents management.

3. Proper disposal of dyes.

4. Proper disposal of petroleum products and spent lubricants.

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

c. Good Housekeeping (No additional requirements).

d. Inspections.

In addition to the inspection requirements outlined in Part III.G, 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.

The Permittee shall describe and implement measures that prevent or minimize contamination of stormwater from material handling operations by using the following:

1. Spill and overflow protection.

2. Covering or enclosing areas where the transfer of materials occurs. The Permittee shall address the replacement or repair of leaking connections, valves, transfer lines, and pipes that carry chemicals, dyes, or wastewater.

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 (No additional requirements).

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

c. Potential Pollutant Sources.

The Permittee shall describe the following additional sources and activities that have potential pollutants associated with them:

1. Backwinding.

2. Beaming.

3. Bleaching.

4. Backing bonding.

5. Carbonizing.

6. Carding.

7. Cut and sew operations.

8. Desizing.

9. Drawing.

10. Dyeing locking.

11. Fulling, knitting.

12. Mercerizing.

13. Opening.

14. Packing.

15. Plying.

16. Scouring.

17. Slashing.

18. Spinning.

19. Synthetic-felt processing.

20. Textile waste processing.

21. Tufting.

22. Turning.

23. Weaving.

24. Web forming.

25. Winging.

26. Yarn spinning.

27. Yarn texturing.

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 V-1, below:

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

Subsector Parameter Benchmark Value
V1 - Textile, Fabric, & Apparel Manufacturing, Leather & Leather Products Solids, Total Suspended (TSS) 100 mg/L 1

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