(a)
Emission Standards for New Stationary Diesel-Fueled CI Engines ( >50
				  bhp) Used in Agricultural Operations.
(1) As of January 1, 2005, except as provided
				  in sections
				  93115.3,
				  93115.8(a)(1)(A)5.,
				  and 93115.8(a)(2), no person shall sell, purchase, or lease for use in
				  California any new stationary diesel-fueled engine to be used in agricultural
				  operations that has a rated brake horsepower greater than 50, or operate any
				  new stationary diesel-fueled engine to be used in agricultural operations that
				  has a rated brake horsepower greater than 50, unless the engine meets all of
				  the following emission performance standards (which are summarized in Table
				  6.):

(A)
Diesel PM Standard:
1. New
				  agricultural stationary diesel-fueled CI engines, used in all agricultural
				  operations except generator set applications with a maximum rated horsepower
				  greater than 50 but less than 100 shall emit no more than 0.30 g/bhp-hr diesel
				  particulate matter (PM) limit or shall meet the standards, as specified in the
				  Off-Road Compression- Ignition Engine Standards for off-road engines of the
				  same maximum rated power (title 13, CCR, section
				  2423), in effect on the date of
				  acquisition or submittal, as defined in section
				  93115.4, whichever is more
				  stringent; and
2. New agricultural
				  stationary diesel-fueled CI engines, used in all agricultural operations except
				  generator set applications with a maximum rated horsepower greater than or
				  equal to 100 but less than 175 shall emit no more than 0.22 g/bhp-hr diesel
				  particulate matter (PM) limit or shall meet the standards, as specified in the
				  Off-Road Compression-Ignition Engine Standards for off-road engines of the same
				  maximum rated power (title 13, CCR, section
				  2423), in effect on the date of
				  acquisition or submittal, as defined in section
				  93115.4 whichever is more
				  stringent; and
3. New agricultural
				  stationary diesel-fueled CI engines, used in all agricultural operations except
				  generator set applications with a maximum rated horsepower greater than or
				  equal to 175 shall emit no more than 0.15 g/bhp-hr diesel PM or shall meet the
				  standards, as specified in the Off-Road Compression Ignition Engine Standards
				  for off-road engines of the same maximum rated power (title 13, CCR, section
				  2423), in effect on the date of
				  acquisition or submittal, as defined in section
				  93115.4, whichever is more
				  stringent; and
4. New agricultural
				  stationary diesel-fueled CI engines, used in generator set applications with a
				  maximum rated horsepower greater than 50, shall emit no more than 0.15 g/bhp-hr
				  diesel PM, or shall meet the standards, as specified in the Off-Road
				  Compression-Ignition Engine Standards for off-road engines of the same maximum
				  rated power (title 13, CCR, section
				  2423), in effect on the date of
				  acquisition or submittal, as defined in section
				  93115.4, whichever is more
				  stringent;
5. On a site-specific
				  basis, a District may extend compliance with sections
				  93115.8(a)(1)(A)1.
				  through 4. up to four years provided:
a. The
				  District determines that an engine meeting sections
				  93115.8(A)1.
				  through 4. would exceed the District's threshold for significant risk pursuant
				  to H&SC section
				  44391 (AB 2588 "Hot Spots"
				  Program), and
b. No later than four
				  years after the applicable initial compliance date for sections
				  93115.8(a)(1)(A)1.
				  through 4., one of the following is installed:
(i.) an electric motor;
(ii.) an engine greater than 50 bhp but less
				  than 75 bhp that does not exceed 0.02 g/bhp-hr PM; or
(iii.) an engine greater than 75 bhp that
				  does not exceed 0.01 g/bhp-hr diesel
				  PM.
