METHANE IN AIR QUALITY AND AUTOMOBILE EXHAUST EMISSION STANDARDS

DIFFERENCES IN THE EVOLUTION OF THE MEASUREMENT OF HYDROCARBONS IN THE ATMOSPHERE AND IN MOTOR VEHICLE EMISSIONS HAVE RESULTED IN THE PRESENT SITUATION IN WHICH ATMOSPHERIC CONCENTRATIONS OF HYDROCARBONS AND THE NATIONAL AIR QUALITY STANDARDS FOR HYDROCARBONS ARE REPORTED ON A NON-METHANE (EXCLUDING METHANE) BASIS WHEREAS MOTOR VEHICLE EMISSION CONCENTRATIONS ARE REPORTED ON A TOTAL HYDROCARBON (INCLUDING METHANE) BASIS. IT IS CONCLUDED THAT THE 1975 MOTOR VEHICLE EMISSION STANDARD FOR HYDROCARBONS SHOULD REFLECT ONLY THE NON-METHANE PORTION OF THE TOTAL HYDROCARBON EMISSIONS. A POSSIBLE METHOD FOR DEVELOPING THESE STANDARDS IS GIVEN. /AUTHOR/
