This webpage provides important information that will assist you in complying with the Santa Barbara County Air Pollution Control District's requirements for wineries. 

Santa Barbara County APCD's 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.  Please call the APCD at the number below (or 961-8800) for additional information or clarification.

  • 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 APCD 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 APCD's Annual Winery Emissions Spreadsheet for this calculation.   Facilities that require a permit also need to assess their daily emissions.  The latest version of APCD's Winery Spreadsheet is available to perform these additional calculations.  Depending on the size of winery, requirements such as a Best Available Control Technology 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).  For units installed prior to January 17, 2008, permit applications are due by no later than April 16, 2008 using APCD Form -60.  Units installed after January 16, 2008 require an APCD 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 APCD'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 an APCD 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 permit 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 APCD permit prior to purchasing a new diesel generator.  To apply for a permit, use APCD 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 APCD'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 APCD Rule 1201 and the State's ATCM regulation.  This does not apply to engines that power vehicles (e.g., tractors, bull dozers, front-end loaders) or wind machines.  Existing AG engines are required to submit a registration application to the APCD 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 APCD prior to purchasing a diesel engine if you are unsure.  To apply for an AG engine registration, use APCD Form AG-1.  For detailed information, see the APCD's AG Engine Webpage.
