Stormwater Technical Assistance
EPA completed its stormwater technical assistance series with the municipalities of Milford, Somerville, and Stoughton in May. The main themes that emerged as part of this series were focused on streamlining maintenance requirements of existing structural stormwater controls to ensure proper operations and efficient ways to estimate the cost or time required for this maintenance. The University of New Hampshire Stormwater Center updated its SCM Performance Calculator (updated version available soon), which quantifies water quality performance using the MS4 permit performance curves and now includes person hour estimates for maintenance of stormwater controls.
Another theme that was important to the participating municipalities was to learn about a successful self-certification program for maintenance of privately owned structural controls. EPA invited the City of Lowell to provide an overview of setting up and managing their self-certification program for privately owned stormwater controls.
