EMISSION INVENTORY SOURCE CATEGORY
Miscellaneous Processes / Residential Fuel Combustion |
610-606-1220-0000 | (47209) | Residential Distillate Oil Combustion | |
610-995-0120-0000 | (47217) | Residential L.P.G. Combustion |
METHOD SUMMARY
This category includes 1991 distillate oil and liquid petroleum gas (LPG) emissions occurring in the residential sector. Distillate oil for heating is used only in older homes and remote areas where natural gas lines are not available. LPG is a clean burning fuel and can easily be transported.
ACTIVITY DATA SOURCE: Activity is based on the number of housing units, population, and LPG and distillate oil capacities. The 1991 Fuels Report Working Paper published by the California Energy Commission was used to determine energy demand for 1990 by fuel type in terms of the number of houses heated by a specific fuel in a particular area. Heating degree days (HDD) are used to estimate how many heating days are likely to occur in a particular area. An HDD is a measure of how cold a location was over a period of time, relative to a base temperature. For this methodology, the base temperature is 65 degrees F, and the HDD is the difference between the base temperature and the day's average temperature.
EMISSION FACTOR SOURCE: U.S. EPA's AP-42.
TEMPORAL DATA:
Daily Activity:
Daily activity is highest during the evening and early morning hours. Weekly Activity:
The activity is uniform seven days a week. Monthly Activity:
Activity is highest from October to late April. DATE OF THE LAST UPDATE: March 1993
GROWTH PARAMETER: Housing Units
