In early April 2020, the Minnesota Pollution Control Agency (MPCA) released revised SRVs for contaminated sediment. These revised values slightly relax regulations placed on sediment disposal. The graphic below compares the new regulations with the old regulations.
SRV levels indicate the concentration of polycyclic aromatic hydrocarbons (PAHs) that have accumulated in some stormwater pond sediments around the state. PAHs break down over time and can be transported via stormwater runoff.
The adjustment in regulations creates cost-saving opportunities when managing stormwater maintenance projects.
