District rules and regulations may apply to various aspects of the wine-making process. This may include the need to obtain one or more permits or may require you to apply for a written request for an exemption from permit. Certain equipment items have emission standards that must be met upon installing and/or replacing existing equipment (e.g., small boilers, large water heaters, diesel engines) as well as future compliance deadlines for existing equipment (e.g., small boilers, large water heaters and diesel engines used in the vineyards). The following summarizes the possible requirements.
Fermentation and Aging/Storage: Emissions of ethanol, a reactive organic compound, occur during the fermentation and aging/storage step in the wine-making process. Aging/storage emissions are only counted when the wine is stored in oak barrels. The District requires a permit for the fermentation and storage tanks (including vats). Low-production wineries may qualify for a written determination of exemption if the annual emissions of ethanol are less than 1 ton per year. As a general rule-of-thumb, facilities that produce less than 25,000 cases per year would qualify for the written exemption. You may use the District’s Annual Winery Emissions Spreadsheet for this calculation. Facilities that require a permit also need to assess their daily emissions. The latest version of the District’s Winery Spreadsheet is available to perform these additional calculations. Depending on the size of winery, requirements such as a Best Available Control Technology (BACT) analysis and emission offsets may be required. The written exemption and permit application forms are found below.
Small Boilers / Large Water Heaters: Permits are required for any individual (or grouping) of boilers or large water heaters with a rated heat over 2.0 million BTUs per hour (MMBtu/hr). Units installed after January 16, 2008 require a District permit prior to installation, and the unit must comply with the requirements of APCD Rule 360 and/or Rule 361. Use Form -61 and Form -01 for new units. For detailed information, see the District’s Boiler and Water Heater Webpage.
Diesel-Fired Emergency Standby Generator Engines: Diesel-fired emergency generator sets with engines rated at 50 bhp and greater require a District permit and must also comply with the State’s Stationary Diesel Engine ATCM. Emergency generator sets using spark ignited engines (e.g., natural gas, propane) are not subject to the State ATCM and are exempt from APCD permitting if they are operated less than 200 hours per year, have an hour meter, and a log is maintained for each use. New diesel generators are required to meet specific emission standards and typically preclude the purchase of used equipment. We strongly advise that you apply for and obtain your District permit prior to purchasing a new diesel generator. To apply for a permit, use District Form -34E, Form -34R and Form -01. If the diesel generator was installed prior to January 2005, then use Form -35 in lieu of Form -34E. For detailed information, see the APCD’s Diesel Engine Webpage.
Diesel-Fired Emergency Firewater Pump Engines: The requirements for diesel-fired firewater pumps are similar to diesel generators above. Due to NFPA requirements, there are some specific distinctions that apply to diesel firewater pumps. Specifically, existing units installed prior to January 2005 are allowed additional maintenance and testing hours if the NFPA standard is adhered to and new units are provided additional engine compliance options. For detailed information, see the District’s Diesel Engine Webpage.
Diesel Engines Used in the Vineyards (AG Engines): Diesel engines used in the vineyard are classified “agricultural.” Stationary and portable engines rated at 50 bhp or greater are subject to the registration requirements of District Rule 1201 and the State’s ATCM regulation. This does not apply to engines that power vehicles (e.g., tractors, bulldozers, front-end loaders). Existing AG engines are required to submit a registration application to the District by no later than March 1, 2008. Registration applications for new AG engines are required to be submitted to the APCD within 90 days of installation. New diesel AG engines are required to meet specific emission standards and typically preclude the purchase of used equipment. We strongly advise that you contact the District prior to purchasing a diesel engine if you are unsure. To apply for an AG engine registration, use District Form AG-1. For detailed information, see the District’s AG Engine Webpage.
