Summary

EPA is providing notice of a proposed administrative penalty settlement with Simplot Transportation for violations of the Clean Water Act at its facility located in Caldwell, Idaho. 

EPA alleges that the respondent failed to conduct routine inspections, failed to conduct quarterly visual assessments, failed to conduct benchmark sampling, and failed to sign and certify reports. EPA also alleges the respondent is missing information in the annual report, missing employee training records, and missing information on the storm water pollution prevention plan map.

This action is being simultaneously commenced and concluded in a legal document called an Expedited Settlement Agreement. Under the proposed agreement (see "Related Documents" below), Simplot Transportation will pay a civil penalty of $3,418.

Respondent

323 La Fond Street
Caldwell, Idaho 83605

Legal authority

The requirements that apply to public comment and participation are set forth in Clean Water Act section 309(g)(4) and 40 CFR § 22.45.
