Proper soil erosion and sedimentation control are essential to protect Michigan’s water quality, prevent sediment runoff, and preserve our natural resources. The LMAS Health Department enforces regulations under Part 91 of Act 451, which governs soil erosion and sedimentation control for construction and land-disturbing activities.

Permit Issuance and Inspections

To ensure compliance with state regulations, the Sanitarian conducts an inspection of the proposed site to evaluate the scope of the earth change. Based on the findings, the Sanitarian will issue a permit that outlines specific erosion and sedimentation control measures to minimize environmental impact during the project. The goal is to prevent soil erosion, which can negatively affect water quality by introducing sediment into lakes, streams, and other water bodies.

225 Square Foot Exemption Permit

In certain cases, a 225 square foot exemption permit waiver may be granted for minor earth changes. To qualify for this exemption, the landowner must provide a signed affidavit stating the following:

• The earth change will disturb less than 225 square feet of land.
• The earth change will not contribute sediment to lakes, streams, or other water bodies.

This exemption is intended to simplify the permitting process for small-scale earth changes that do not pose significant environmental risks. However, even if an exemption is granted, the landowner is still responsible for ensuring proper erosion control measures are followed to prevent any negative impact on water quality.

Why Erosion Control is Important

Erosion control is crucial in preventing soil and sediment from washing into water bodies, where it can degrade water quality, harm aquatic life, and damage ecosystems. Effective sedimentation control practices also help preserve the integrity of the land by reducing soil loss, promoting vegetation growth, and protecting property values.
