Summary

EPA is providing notice of an opportunity for the public to comment on a proposed Settlement Agreement with an administrative civil penalty assessment against Haddonstone (USA) Ltd (Haddonstone). In the Settlement Agreement, EPA alleges Haddonstone discharged pollutants in stormwater into navigable waters without a permit, in violation of section 301(a) of the Clean Water Act (CWA) at its facility in Pueblo, Colorado.

Proposed Action

EPA alleges that Haddonstone violated the CWA section 301(a) by discharging stormwater runoff to the County of Pueblo’s Municipal Separate Storm Sewer System (MS4) that flows to the Arkansas River without coverage under the Colorado Discharge Permit System (CDPS) Industrial Stormwater General Permit for Non-Extractive Industries (Permit) for its facility in Pueblo, Colorado. Under the proposed Settlement Agreement, Haddonstone has agreed to pay a civil administrative penalty of $5,000 to resolve its civil penalty liability for these alleged violations.

The addresses of EPA and Haddonstone are listed below:
