What level of fuel oil storage is prohibited above ground for 1-2 family dwellings?

The prohibition on storage levels for fuel oil above ground in 1-2 family dwellings is primarily concerned with safety and environmental regulations. In North Carolina, the Mechanical Code specifies that above-ground fuel oil storage tanks should typically not exceed 660 gallons in capacity for residential properties.

A storage capacity greater than this can increase risks related to spills, leaks, and potential fire hazards. By setting 660 gallons as the limit, the code helps ensure that the risk associated with larger quantities of fuel, such as environmental contamination in the event of a leak, or heightened fire risk, is effectively mitigated for residential settings.

In this context, 800 gallons exceeds the permissible storage level, thus it is not advisable for residential properties as it could lead to greater liability and safety concerns.
