SDAPCD's Source Emission Testing Program mission is to measure pollutant emissions from facilities to determine if the emissions meet the facilities operational permit emission limits. This effort requires conducting measurements conducted at the facilities premise at the point of release into the atmosphere and can be at elevated locations.
