Next Deadline for Ag Motors in SJV
Growers in the eight-county San Joaquin Valley Air Pollution Control District have until January 2010 to replace older, high-polluting, Tier 0 diesel engines greater than 50 hp with EPA-certified Tier 3 or Tier 4 engines. The rule is the latest installment in complying with District Rule 4702, which regulates air pollution emissions from ag engines not used in tractors or ag implements, such as irrigation pump engines. Growers statewide will need to meet a similar requirement by January 2011 under parallel rules by the State Air Board.
In addition, San Joaquin Valley growers after January face more onerous permitting requirements if they plan to install or modify ag engines, depending on whether or not they qualify as a "significant polluter." The cut-off for "significant polluter" will be lowered from 12.5 tons per year due to the severe non-attainment for ozone status of the SJV.
The classification is based on NOx and VOC emissions determined by type and number of internal combustion motors and hours of operation. Estimates indicate growing operations with as few as two or three irrigation pump motors greater than 50 hp may exceed the limit that allows them to register under the District’s Permit Exempt Equipment Registration (PEER) program. Those growers will instead need an "Authority to Construct" permit, which requires significantly more process and paperwork.

Now that harvest is winding down, it's the perfect time to update your records. Create or update a detailed diagram of adjacent land use, operations and influences, so that you are able to identify potential sources of contamination due to runoff and drift. Create, implement and document procedures to reduce the likelihood of contamination to your almonds throughout the year.
