Printing - Publishing Industrial Sector - MPCA Permit

The Minnesota Pollution Control Agency (MPCA) has issued its revised multi-sector industrial stormwater discharge general permit (MSGP). This permit will replace the existing industrial stormwater permit, which expired in October of 2002.

All manufacturing, industrial and “industrial-like” sites that require a permit to discharge stormwater will be required to come into compliance with the revised permit, and to submit an application for permit coverage by either March 1, July 1 or September 1, depending on their industrial sector.

The revised Minnesota permit details requirements for 29 different industrial sectors. The requirements described below are for the Printing and Publishing Sector (Sector X). Sector X covers a fairly broad range of facility types, including book printing, commercial printing and lithographics; platemaking and related services; commercial printing, gravure; and other types of commercial printing. These requirements are in addition to permit requirements that apply to all sectors.

Preventative Maintenance:
The SWPPP must implement measures that prevent or minimize contamination of stormwater runoff from blanket wash areas, and mixing solvent areas. Each site must have BMPs that address the replacement or repair of leaking connections, valves, transfer lines, and pipes that may carry chemicals or wastewater.

Stormwater Monitoring Benchmarks:
All facilities are required to conduct visual and chemical (benchmark) monitoring. For benchmark monitoring, the benchmark concentrations for Printing and Publishing (SIC 2711-2796) are:

Total Silver 0.0041 mg/L
TSS 100 mg/L

Note: Benchmark for silver were derived based on the Aquatic Life Standards for these parameters in Minnesota Rules.
