Status
MN Rule 7090.2010, sub.3, Permit section IV.B.2: Erosion Control Practices During Construction: Pond side slopes have
required temporary protection or permanent cover within 200' of surface water.
Compliant
MN Rule 7090.2010, sub.3, Permit section IV.B.3: Erosion Control Practices During Construction: Normal wetted
perimeter of temporary or permanent (connected) ditch that drains water is stabilized within 24 hours (200' back from
surface water).
Compliant
MN Rule 7090.2010, sub.3, Permit section, IV.B.2: Erosion Control Practices During Construction: Other exposed,
erodable soils with positive slopes have stabilization BMPs that are installed appropriately and functional.
Compliant
MN Rule 7090.2010, sub.3, Permit section IV.B.4: Erosion Control Practices During Construction: Temporary or
permanent energy dissipation present at outlets connected to surface water within 24 hours.
Not Applicable
MN Rule 7090.2010, sub.3, Permit section IV.C.1: Sediment Control: Adequate control (or minimizing) of sediment
discharges (no additional up gradient controls required).
Non-Compliant
[localized] SE corner of project is exposed with steep slopes to a silt fence and established landscaped yards border
the project. Sediment is leaving the site from the last rain event.
Establish additional upslope controls. Additional sediment controls or temporary stabilization needed on the
exposed slopes within 5 days.

Status
MN Rule 7090.2010, sub.3, Permit section III.B: Sediment Control: Temporary sedimentation basins (disturbance>10
acres, or >5 acres near special water areas) present.
Compliant
MN Rule 7090.2010, sub.3, Permit section IV.C.4: Sediment Control: Inlet control BMP(s) present and functional.
Not Applicable
MN Rule 7090.2010, sub.3, Permit section IV.C.2: Sediment Control: Perimeter controls present down gradient prior to
land disturbing activities.
Compliant
MN Rule 7090.2010, sub.3, Permit section III.D: SWPPP:Stormwater Pollution Prevention Plan available on-site.
Compliant
MN Rule 7090.2010, sub.3, Permit section III.A: SWPPP:The Stormwater Pollution Prevention Plan adequately
addresses who is responsible on-site, the process for adding BMP(s) when necessary, installation timing or phasing, the
potential for discharge to all water resources, dewatering and basin drawdown, and final stabilization.
Compliant
MN Rule 7090.2010, sub.3, Permit section 1I1.A: SWPPP:The Stormwater Pollution Prevention Plan addresses temporary
sediment basins and includes adequate sizing, design to prevent short-circuiting, removal of floating debris, drawdown
allowance, energy dissipation, and emergency spillways.
Compliant
MN Rule 7090.2010, sub.3, Permit section III.A: SWPPP:The Stormwater Pollution Prevention Plan includes a permanent
stormwater system(s), the system meets the requirements for treatment for wet sediment basins, infiltration/filtration,
regional ponds, and combination of practices, and the method has MPCA approval.
Compliant
MN Rule 7090.2010, sub. 3, Permit section III.A: SWPPP:The Stormwater Pollution Prevention Plan meets all other
requirements not identified as specific inspection items.
Compliant
MN Rule 7090.2010, sub.3, Permit Section IV E. 1: Inspections: Performed required inspections/maintenance (1 per 7
days or 24 hours of 0.5 precipitation).
Compliant
MN Rule 7090.2010, sub.3, Permit section IV E. 1: Inspections: Inspections/maintenance documentation met all
requirements (date, name findings, corrective actions, rainfall, changes to SWPPP).
Compliant
MN Rule 7090.2010, sub.3, Permit section IV.E.4: Maintenance: Erosion and sediment control BMP(s) functional (needs
no repair, replacement or enhancement).
Non-Compliant
[localized] Silt fence maintenance needed in the ravine area; silt fence has been undermined and has needed
maintenance for weeks.
Enhance / maintain silt fence with a rock weeper immediately.

Status
MN Rule 7090.2010, sub.3, Permit section IV.EA.b: Maintenance: Temporary sedimentation basin maintenance
performed (removed sediment>half basin volume).
Non-Compliant
Temporary sediment basin along the south area of site has been graded to take the temporary outlet off line.
Re-establish temporary outlet for the basin within 48 hours. An EOF is needed for the basin within 48 hours as
well.
MN Rule 7090.2010, sub.3, Permit section IV.EA.c: Maintenance: Sediment deposits in ditches or surface waters
removed.
Compliant
MN Rule 7090.2010, sub.3, Permit section IV.EA.d: Maintenance: No sediment tracking on paved surfaces at exits.
Non-Compliant
Both site exits have sediment tracking from them onto Galpin and residential street.
Scrap and sweep streets by the end of the work day (within 4 hours) and re-establish rock exits within 24 hours.
MN Rule 7090.2010, sub.3, Permit section III.C: Stormwater Management: Required to have stormwater management
method and method is in place.
Compliant
MN Rule 7090.2010, sub.3, Permit section III.C: Stormwater Management: Pretreatment required and in place.
