The federal pretreatment regulations establish criteria for agencies such as the District to use to determine if the violations of SIUs are classified as Significant Non - Compliance (SNC). If a business is determined to be in SNC, the District is required to publish certain information about the violation in the newspaper at least annually. In 2005, Source Control staff initiated a program, at the Board's request, to work more closely with the regulated businesses to understand the actions they could take to minimize the events when they would meet the SNC criteria. This program has been very successful and the number of businesses reported in SNC has been significantly reduced. BUSINESSES IN SNC FOR 2012 Unfortunately, three businesses were determined to meet the SNC criteria during calendar year 2012: • Acme Fill Corporation for mercury limit violations • Diablo Valley College for cyanide limit violations • Nu West Textiles Group for Oil & Grease (animal /vegetable) limit violation The information that will be published in the Contra Costa Times is included in the enclosed document. The information includes any other violations cited during calendar year 2012 that may not be subject to SNC criteria. Staff is available to answer any questions about the conditions that resulted in the citations of these companies or the SNC standards.
