Estimating Receptor Distances

The receptor distance is the distance from outside the boundaries of a facility where a person may experience exposure to diesel exhaust due to the operation of a stationary diesel-fueled CI engine measured in meters.  Receptor locations include, but are not limited to, residences, businesses, hospitals, daycare centers, and schools (see definition below).


Residential Receptor Locations:  Include current residential land uses and areas that may be developed for residential uses in the future, given land use trends in the general area.  The residential receptor distance is defined as the closest distance between a stationary diesel-fueled CI engine at the facility and the property boundary of any one of the residential receptor locations.


Commercial Receptor Locations:  Include areas zoned for manufacturing, light or heavy industry, retail activity, or locations that are regular work sites.  For facilities with a single stationary diesel-fueled CI engine, the receptor distance is from the stack to the nearest receptor location. 


Schools or School Grounds:  means any public or private school, including juvenile detention facilities, used for purposes of the education of more than 12 children in kindergarten or any of grades 1 to 12.  This definition does not include any private school in which education is primarily conducted in private homes.  School or School Grounds includes any building or structure, playground, athletic field, or other areas of school property, but does not include unimproved school property.
