1. May be subject to additional emission limitations as specified in current district rules, regulations, or policies governing distributed generation.
1. (4) Emissions Standards: All new stationary prime diesel-fueled CI engines (> 50 bhp) shall meet the applicable emission standards for all pollutants for the model year and maximum horsepower rating as specified in Table 4 Emission Standards for New Stationary Prime Diesel-Fueled CI Engines in effect on the date of acquisition or submittal, as defined in section 93115.4;
2. (4) New stationary prime diesel-fueled CI engines that are used to provide electricity near the place of use (also known as “distributed generation”) may be subject to additional emission limitations as specified in current district rules, policies, or regulations governing distributed generation;
3. (5) The District may establish more stringent diesel PM, NMHC+NOx, HC, NOx, and CO emission rate limits on a site-specific basis.
(b) In-Use Stationary Prime Diesel-Fueled CI Engine (>50 bhp) Emission Standards. Except as provided in section 93115.3, no owner or operator shall operate an in-use stationary prime diesel-fueled CI engines (> 50 bhp) in California unless it meets the following requirements (which are summarized in Table 5):

1. The option to comply with the Tier 1 standards is available only if no off-road engine certification standards have been established for an off-road engine of the same model year and maximum rated power as the new stationary emergency standby diesel-fueled CI engine.
1. (1) Diesel PM Standards: All in-use stationary prime diesel-fueled CI engines (> 50 bhp) certified in accordance with the Off-Road Compression-Ignition Engine Standards (title 13, CCR, section 2423) shall comply with either option 1 or option 2 below. All engines not certified in accordance with the Off-Road Compression- Ignition Engine Standards (title 13, CCR, section 2423) shall comply with option 1, option 2, or option 3 below:
  1. (A) Option 1: Reduce the diesel PM emission rate by at least 85 percent, by weight, from the baseline level, in accordance with the appropriate compliance schedule specified in sections 93115.11 and 93115.12;
  2. (B) Option 2: Emit diesel PM at a rate less than or equal to 0.01 g/bhphr in accordance with the appropriate compliance schedule as specified in sections 93115.11 and 93115.12;
  3. (C) Option 3: Reduce the diesel PM emission rate by at least 30% from the baseline level, by no later than January 1, 2006, and emit diesel PM at a rate of 0.01 g/bhp-hr or less by no later than July 1, 2011.
2. (2) Additional Standards:
  1. (A) Meet the applicable HC, NOx, NMHC+NOx, and CO standards for off-road engines of the same model year and maximum rated power as specified in the Off-Road Compression-Ignition Engine Standards (title 13, CCR, section 2423). If no standards have been established for an off-road engine of the same model year and maximum rated power as the in-use stationary prime diesel-fueled CI engine, then the in-use stationary prime diesel-fueled CI engine shall meet the Tier 1 standards in title 13, CCR, section 2423 for an off-road engine of the same maximum rated power, irrespective of the new stationary emergency standby diesel-fueled CI engine's model year; or
  2. (B) Not increase CO emission rates by more than 10% above baseline; and
    Not increase HC or NOx emission rates by more than 10% above baseline, or
    Not increase the sum of NMHC and NOx emission rates above baseline.
  Owners or operators that choose to meet the diesel PM limits defined in section 93115.7(b) with emission control strategies that are not verified through the Verification Procedure shall either:
3. (3) The District may establish more stringent diesel PM, NMHC+NOx, HC, NOx, and CO emission rate standards.
