District Rule 2280 includes operating requirements for registered portable equipment. These requirements were designed to ensure that operation of portable equipment does not result in excessive air emissions. The CA Airborne Toxic Control Measure for Diesel-Fueled Portable Engines (ATCM) requires new portable equipment to be certified to the latest available tier certification level.
The specific technology requirements in Rule 2280 vary with equipment type. In most cases various options are provided. One requirement for existing diesel engines, for example, is that they are required to either meet a ten grams per horsepower hour emission limit for oxides of nitrogen, or have their timing retarded four degrees from standard. Other requirements apply for other pollutant and equipment types. Each registration issued by the District includes the conditions necessary to ensure that the equipment operates in compliance with requirements of District rules.
