(2)           "Emergency use internal combustion engines" means stationary internal combustion engines used to drive pumps, aerators, and other equipment only during the loss of primary power at the facility that is beyond the control of the owner or operator of the facility or during maintenance when necessary to protect the environment.  An emergency use internal combustion engine may be operated periodically to ensure that it will operate.

(c)  For the purposes of this Rule, potential emissions for emergency generators and emergency use internal combustion engines shall be determined using actual fuel consumption.

(d)  Any facility whose emergency generators and emergency use internal combustion engines consume less than:

(1)           322,000 gallons per year of diesel fuel for diesel-powered generators;

(2)           62,500,000 cubic feet per year of natural gas for natural gas-powered generators;

(3)           1,440,000 gallons per year of liquified petroleum gas for liquified petroleum gas-powered generators; and

(4)           50,800 gallons per year of gasoline for gasoline-powered generators,

shall be exempted from the requirements of Section .0500 of this Subchapter.

(e)  The owner or operator of any emergency generator or emergency use internal combustion engine exempted by this Rule from Section .0500 of this Subchapter shall submit to the regional supervisors of the appropriate Division regional office by March 1 of each year a report containing the following information:

(1)           the name and location of the facility;

(2)           the types and quantity of fuel consumed by emergency generators and emergency use internal combustion engines; and

(3)           the signature of the appropriate official as identified in Rule .0304(j) of this Subchapter certifying as to the truth and accuracy of the report.

(f)  The owner or operator of any facility exempted by this Rule from Section .0500 of this Subchapter shall provide documentation of types and quantities of fuel consumed to the Director upon request.  The owner or operator of a facility exempted by this Rule from Section .0500 of this Subchapter shall retain records to document types and quantities of fuels consumed for each of the previous three years.

(g)  For facilities covered by this Rule, the owner or operator shall report to the Director any exceedance of a requirement of this Rule within one week of its occurrence.
