X. Printing and Publishing

1. Authorized Stormwater Discharges

The requirements in Sector X apply to stormwater discharges associated with industrial activity from printing and publishing facilities as identified by the industrial activity code specified in Table 5 of Appendix D.

2. Industrial Activities Authorized by Sector X

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

a. Book printing.

b. Commercial printing and lithographics.

c. Platemaking and related services.

d. Commercial printing, gravure.

e. Commercial printing, not elsewhere classified.

3. Limitation on Authorization (No Additional Limitations)

4. Sector-Specific Definitions (No Additional Definitions)

5. Stormwater Controls Measures

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.

The Permittee shall describe and implement measures that prevent or minimize contamination of stormwater runoff from blanket wash areas and mixing solvent areas. The Permittee shall have BMPs that address the replacement or repair of leaking connections, valves, transfer lines, and pipes that may carry chemicals or wastewater.

f. Spills and Leaks (No additional requirements).

g. Management of Runoff (No additional requirements).

h. Other Industry Specific 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 that have potential pollutants associated with them:

1. Significant dust or particulate generating processes, and onsite waste disposal practices (e.g. blanket wash).

2. The Permittee shall also identify the pollutant parameter (e.g. oil and grease, scrap metal) associated with each pollutant source.

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 X-1, below:

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

Subsector Parameter Benchmark Values
X1 - Printing and Publishing Solids, Total Suspended (TSS) 100 mg/L 2
Silver, Total (as Ag) 0.0041 mg/L 1

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