This Sonoma County, California-based client operates a winery and vineyards and produces and distributes Chardonnay and Pinot Noir wines throughout the United States and internationally. To support winemaking operations, the company maintains several oil sources that are regulated under Spill Prevention, Control, and Countermeasure (SPCC) Plan and Stormwater Pollution Prevention Plan (SWPPP) requirements.
EHS Support was asked to update the winery’s SPCC Plan and SWPPP in response to a variety of comments received from a third-party environmental audit. To initiate the project, EHS Support conducted a thorough site inspection to identify all regulated oil sources of 55 gallons or more, potential pollutant sources located indoors and outdoors at the facility, baseline and advanced best management practices, and confirmed drainage patterns and outfall locations. California requires both indoor and outdoor potential pollutant sources to be identified, along with locations where these materials are received, stored, used, and shipped.
Based on this site information, EHS Support updated pollutant source maps and drainage maps to accurately reflect current conditions, reviewed all aspects of the SPCC Plan and SWPPP in regards to regulatory requirements, and prepared an Action Item table for each plan that identified key tasks and associated deadlines to help ensure the plans could be fully implemented. A California-registered Professional Engineer reviewed and certified the SPCC Plan. With the updated plans, the winery has the necessary tools to comply with the stormwater general permit and the oil pollution prevention regulations.
