Caltha LLP Project Summary
Project: Response To MPCA NOV For Industrial Stormwater Discharges and Non-Storm Water DischargeClient: Transportation Sector
Location(s): Minnesota
Key Elements: Compliance with No Exposure Certification, Compliance with prohibition of unauthorized non storm water discharge
Overview: In a routine compliance inspection of industrial sites which had submitted no exposure certifications (NEC) being conducted by the State, this facility was found to be in non-compliance with both the conditions of the NEC and was also found to be discharging wash water without a permit. The facility was placed in enforcement action to resolve these issues.
Caltha LLP was retained by the facility to assist them in evaluating requirements to meet the NEC and to identify options for addressing unpermitted discharge. Working with facility management, it was determined that costs for necessary corrective actions to comply with the NEC were too high compared to costs to obtain and comply with an industrial stormwater discharge permit. The facility terminated its NEC and applied for permit coverage. Caltha assisted the facility in preparing a facility SWPPP using our Minnesota SWPPP template and a permit compliance plan. Alternate off-site facilities were found to eliminate the discharge of unauthorized wastewater releases from the facility.
