I.	A final report of the results of any on-site testing shall be submitted to the Office of Air Resources no later than sixty (60) days following completion of testing.
43.10	Credit for Concurrent Emissions Reductions
43.10.1	Flared Fuels
A.	If a distributed generator uses fuel that would otherwise be flared, the emissions that were or would have been produced through the flaring can be deducted from the actual emissions of the distributed generator for the purposes of calculating compliance with the emission standards in this rule. If the actual emissions from flaring can be documented, they may be used as the basis for calculating the credit, subject to the approval of the Office of Air Resources. If the actual emissions from flaring cannot be documented, then the following default values shall be used:
Waste, Landfill, Digester Gases
43.10.2	Combined Heat and Power
A.	CHP installations must meet the following requirements to be eligible for emissions credits related to thermal output:
a.	The power-to-heat ratio must be between 4.0 and 0.15.
b.	The design system efficiency must be at least 55 percent (55%).
B.	A CHP system that meets these requirements can receive a compliance credit against its actual emissions based on the emissions that would have been created by a conventional separate system used to generate the same thermal output. The credit will be subtracted from the actual generator emissions for purposes of calculating compliance with the emission standards in § 43.8.2 of this Part. The credit will be calculated according to the following assumptions and procedures:
1.	The emission rates for the displaced thermal system (e.g. boiler) will be:
a.	For CHP installed in new facilities, the emissions limits applicable to new natural gas-fired boilers in 40 C.F.R. § 60 Subparts Da, Db, Dc, incorporated in § 43.4(A) of this Part, as applicable, in lb/MMBtu.
b.	For CHP facilities that replace existing thermal systems for which historic emission rates can be documented, the historic emission rates in lbs/MMBtu but not more than:
0.3 lbs/MMBtu
0.08 lb/MMBtu
2.	The emissions rate of the thermal system in lbs/MMBtu will be converted to an output-based rate by dividing by the thermal system efficiency. For new systems the efficiency of the avoided thermal system will be assumed to be eighty percent (80%) for boilers or the design efficiency of other process heat systems. If the design efficiency of the other process heat system cannot be documented, an efficiency of eighty percent (80%) will be assumed. For retrofit systems, the historic efficiency of the displaced thermal system can be used if that efficiency can be documented and if the displaced thermal system is either enforceably shut down and replaced by the CHP system, or if its operation is measurably and enforceably reduced by the operation of the CHP system.
3.	The emissions per MMBtu of thermal energy output will be converted to emissions per MWh of thermal energy by multiplying by 3.412 MMBtu/MWhthermal.
4.	The emissions credits in lbs/MWhthermal, as calculated in § 43.10.2(B)(3) of this Part, will be converted to emissions in lbs/MWhemissions by dividing by the CHP system power-to-heat ratio.
5.	The credit, as calculated above in § 43.10.2(B)(4) of this Part, will be subtracted from the actual emission rate of the CHP unit to produce the emission rate used for compliance purposes.
6.	The mathematical calculations set out in §§ 43.10.2(B)(1) through (4) of this Part are expressed in the following formula:
Credit lbs/MWhemissions = [(boiler limit lbs/MMBtu)/(boiler efficiency)] x [3.412/(power to heat ratio)]
43.10.3	End-Use Efficiency and Non-Emitting Resources
When end-use energy efficiency and conservation measures or electricity generation that does not produce any of the emissions regulated herein are installed and operated contemporaneously at the facility where the generator is installed and operated, then the electricity savings credited to the efficiency and conservation measures or supplied by the non-emitting electricity source shall be added to the electricity supplied by the generator for the purposes of calculating compliance with the emission standards of this rule, subject to the approval of the Office of Air Resources and in accordance with any guidelines established by the Office of Air Resources for determining such savings.
43.11	Monitoring Requirements
43.11.1	Emergency Generators
Each emergency generator shall be equipped with a non-resettable elapsed time meter to indicate, in cumulative hours, the elapsed operating time for the unit.
43.11.2	Distributed Generators
If the distributed generator is supplied with fuel from more than one (1) tank or if multiple sources are supplied fuel by one (1) fuel tank, each distributed generator shall be equipped with a non-resettable fuel metering device to continuously monitor the fuel consumption by the unit. Generators whose total capacity is two hundred (200) kW or less will be exempt from this requirement.
43.12	Record Keeping and Reporting
43.12.1	Emergency Generators
A.	The owner/operator shall, on a monthly basis, no later than five (5) days after the first of each month, determine and record the hours of operation for the emergency generator for the previous 12-month period.

4.	The method used to determine the sulfur content of the fuel.
43.12.2	Distributed generators
A.	The owner/operator shall, on a monthly basis, no later than five (5) days after the first of each month, determine and record the fuel use for the distributed generator for the previous 12-month period.
B.	For each shipment of liquid fuel, the owner/operator shall maintain a certification from the fuel supplier that includes the following information:
C.	Distributed generators with electric generating capacity of less than two hundred (200) kW shall be exempt from these requirements.
43.12.3	Availability of Records
Unless the Office of Air Resources provides otherwise in writing, the owner shall maintain each record required by this subsection for a minimum of five (5) years after the date such record is made. An owner shall promptly provide any such record, or copy thereof, to the Office of Air Resources upon request.
43.13	Duty to Comply
A.	Issuance of a general permit pursuant to the provisions of this regulation does not relieve the owner/operator from the responsibility to comply fully with any applicable state or federal air pollution control rules or regulations and any other requirements under local, state or federal law.
B.	Any conditions included with a general permit issued pursuant to this regulation shall have the full force and effect of rules and regulations.
C.	Any person who receives a general permit shall comply with all conditions included with the permit.
D.	Failure to comply with any condition included in a general permit issued pursuant to this regulation shall be considered failure to comply with this regulation.
