Revision as of 20:17, 30 April 2015

AB. Transportation Equipment and Industrial or Commercial Machinery

1. Authorized Stormwater Discharges

The requirements in Sector AB apply to stormwater discharges associated with industrial activity from transportation equipment and industrial or commercial machinery facilities as identified by the industrial activity code specified in Table 5 of Appendix D.

2. Industrial Activities Authorized by Sector AB

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

a. Manufacturing engines and turbines.

b. Manufacturing farm and garden machinery and equipment.

c. Manufacturing construction, mining, and materials-handling machinery and equipment.

d. Manufacturing metalworking machinery and equipment.

e. Manufacturing special industry machinery, except metalworking machinery.

f. Manufacturing general industrial machinery and equipment.

g. Manufacturing refrigeration and service industry machinery.

h. Manufacturing miscellaneous industrial and commercial machinery and equipment.

i. Manufacturing motor vehicles and motor vehicle equipment.

j. Manufacturing aircraft and parts.

k. Manufacturing motorcycles, bicycles, and parts.

l. Manufacturing guided missiles and space vehicles and parts.

m. Manufacturing miscellaneous transportation equipment.

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.

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 (No additional requirements).

f. Spills and Leaks (No additional requirements).

g. Management of Runoff (No additional requirements).

h. Other 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 where any vents and stacks from metal processing and similar operations are exposed to stormwater.

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

c. Potential Pollutant Sources (No additional requirements).

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 AB-1, below:

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

Subsector Subsector Benchmark Value
AB1 - Transportation Equipment and Industrial or Commercial Machinery 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 AB industrial facilities are authorized to use designed infiltration devices or industrial stormwater ponds for stormwater management.
