This is a resolution of a voluntary disclosure by means of an administrative penalty action issued to Northwind Phoenix, LLC (Respondent) pursuant to the EPCRA. The violation involves failure to timely submit annual chemical inventory forms, for its Phoenix, AZ, district cooling and ice manufacturing facility that uses ethylene glycol, mineral oil, chlorodifluoromehtane, and sulfuric acid in an amount that is over the threshold planning quantity. During an environmental audit of its operations, Respondent discovered violations of EPCRA Section 312, and promptly disclosed its violations to EPA. This enforcement action was based on the voluntary self-disclosure by Respondent, and resolved by a CA/FO initiating and resolving the violations pursuant to 40 CFR Sections 22.13 and 22.18. Application of the Audit Policy resulted in 100% penalty mitigation (zero dollars).
