Update your MS4 Permit Program with Data-Driven Compliance

Municipal governments face the daunting task of managing multiple minimum control measures (MCMs) and reporting requirements associated with their MS4 stormwater permit. CloudCompli offers municipalities a cost-effective and innovative way to manage the competing demands of their stormwater program.

Why Use CloudCompli As Your Municipal Stormwater Software?

Ensuring that your separate storm sewer systems comply with state regulations can be time consuming, and reporting on the systems can be even more daunting. CloudCompli removes redundant work through our automated cloud-based systems, saving time and money, minimizing risk and providing clarity on your environmental footprint.

What is the MS4 (Municipal Separate Storm Sewer System) Stormwater Permit?

Created in 1972 by the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) permit program is authorized to state governments by EPA to perform many permitting, administrative, and enforcement aspects of the program. The NPDES MS4 permit requires, permittees to develop and implement a comprehensive Storm Water Management Program (SWMP) that must include:

  • Pollution prevention measures

  • Treatment or removal techniques

  • Monitoring

  • Use of legal authority, and 

Other appropriate measures to control the quality of storm water discharged to the storm drains and thence to waters of the United States.
( See References: NPDES, EPA)


Municipal governments face the daunting task of managing reporting requirements associated with stormwater runoff for large developed areas. Municipalities benefit from the cost-effective and innovative way in which water quality protection programs are managed. Municipalities are often responsible for inspecting hundreds and sometimes thousands of sites.

The Challenge

Municipal Separate Storm Sewer Systems (MS4 Stormwater permits) are the water conveyance systems, including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, channels, and storm drains that are designed to collect and convey stormwater.

The Solution

CloudCompli integrated their GIS data into the digital workflows of site inspections onto the permit management software platform. With the ability to interpret and analyze the inspection data, city managers could better manage scarce resources with greater efficiency (link to Blog on GIS). By integrating GIS layers in CloudCompli, we have created a powerful interactive tool that improves the ability of Municipal Storm Water Divisions and Regional Water Boards to regulate stormwater discharges from municipal separate storm sewer systems (MS4s).
