(3) DG Units that use combined heat and power may be certified to the emission standard in section (a)(2) above if the DG Units are sold with combined heat and power technology integrated into a standardized package by the Applicant and the DG Units achieve a minimum energy efficiency of 60 percent. The efficiency determination shall be based on 100 percent load.

(4) DG Units that are sold with a zero emission technology integrated into a standardized package by the Applicant may have the electrical power output of the zero emission technology added to the electrical power output of the DG Unit to meet the emission standards in (a)(1) and (a)(2) above.

(b) On or after January 1, 2007, any DG Unit subject to this regulation fueled by a fossil fuel must be certified pursuant to section 94204 to the following set of emission standards in Table 2.

DG Units that produce combined heat and power may take a credit to meet the emission standard above. Credit shall be at the rate of one MW-hr for each 3.4 million Btu's of heat recovered. To take the credit, the following must apply:

(1) DG Units are sold with combined heat and power technology integrated into a standardized package by the Applicant; and

(2) DG Units achieve a minimum energy efficiency of 60 percent.

(c) Any DG Unit subject to this regulation and fueled by digester gas, landfill gas, or oil-field waste gas must be certified pursuant to section 94204 to the emission standards in Table 3.

DG Units that produce combined heat and power may take a credit to meet the January 1, 2013, emission standard above. Credit shall be at the rate of one MW-hr for each 3.4 million Btu's of heat recovered. To take the credit, the following must apply:

(1) DG Units are sold with combined heat and power technology integrated into a standardized package by the Applicant; and

(2) DG Units achieve a minimum energy efficiency of 60 percent.

(d) DG Units must meet the applicable emission standards for 15,000 hours of operation when operated and maintained according to the manufacturer's instructions.

(e) By July 2005, the ARB staff must complete an electrical generation technology review to evaluate if the requirements in (b) and (d) above and section 94207 should be modified and report its findings to the Board.
