EPA Region 10 Settles with ZWJ Properties, LLC, Boise, ID for CWA Violations
On April 28, 2021, Region 10 filed a consent agreement and final order resolving violations of the
Clean Water Act by ZWJ Properties, LLC for its Win Hollow Subdivision construction site in Boise,
Idaho. ZWJ Properties had a prohibited discharge and failed to conduct inspections, failed to update
and maintain the Stormwater Pollution Prevention Plan (SWPPP), and failed to install and maintain
Best Management Practices (BMPs) such as erosion and sediment control measures, which resulted in
turbid runoff from the property. Since erosion leads to sediment and other pollutants entering Waters
of the United States, EPA estimates that this action has helped reduce 132,362 lbs of sediment from
discharging off-site and reaching Crane Creek. The Respondent has agreed to pay a penalty of $62,000
and has returned to compliance.
