* Sum of emissions from all emission points of process

3. Geothermal Well Drilling

A person shall not discharge particulates into the atmosphere from any geothermal steam source in excess of the quantity established by the following formula:

y = .00069X + 1.4

where:    
y = is the particulate emission rate limitation in kilograms per hour (averaged over one hour) and X is the steam rate in kilograms per hour passing through a geothermal well drilling operation or an geothermal well being vented for clean out.
