Construction Site Pollutant Control and
Post-Construction Stormwater Management |
| Stormwater runoff from construction activities can have a significant impact on water quality. In addition to sediment, as stormwater flows over a construction site, it can pick up other pollutants like debris, pesticides, petroleum products, chemicals, solvents, asphalts and acids which also contribute to water quality problems (EPA 2004). |
Construction Site
Pollutant Erosion Control
|
Erosion control measures are designed to prevent environmental damage caused by pollution, soil erosion and sedimentation from land development. Construction site erosion control emphasizes the most appropriate set of practices for a specific site, as well as correctly installing and maintaining the selected practices to ensure their effectiveness.
In accordance with fulfilling the Construction Site Pollutant Control requirement of the WI-DNR Stormwater permit, the City of Superior adoped a Site Erosion Control Ordinance in February 2009, to require erosion control best management practices that reduce the amount of sediment and other pollutants leaving construction sites during land development or land disturbing activities. The city requires any land disturbing activity, regardless of size, that has the potential to result in excessive runoff to have a permit. |

Conditions of the ordinance include:
- Apply for an Erosion Control/Grading Permit before undertaking a land disturbing construction activity.
- Submit a permit application, Erosion & Sediment Control Plan and the required fee to the Public Works Department.
- Install all Best Management Practices (BMPs) as identified in the approved Erosion & Sediment Control Plan.
- Maintain all Best Management Practices (BMPs) necessary to meet the requirements until the site has undergone final stabilization.
- All permits are subject to the conditions detailed in the

Post-Construction Stormwater Management |
The Post-Construction Stormwater Management requirement of the City of Superior's WI-DNR Stormwater permit seeks to reduce the amount of post-construction stormwater and associated pollutants reaching our waterways. This requirement regulates post-construction discharges off construction sites of one acre or more of disturbed land. Additionally, the city requires construction sites with less than one acre of land disturbing activity that will result in the addition of 20,000 sq. feet or more of impervious area, to have a permit.
In accordance with fulfilling the Post-Construction Stormwater Management requirement of the WI-DNR Stormwater permit, the City of Superior adopted a Post-Construction Stormwater Management Ordinance in December 2008, to establish long-term, post-construction runoff management requirements that will diminish the threats to public health, safety, welfare and the aquatic environment.
