Subchapter B: Use of Best Available Retrofit Technology and Ultra Low Sulfur Diesel Fuel
Pursuant to § 24-163.7 of the Code, any diesel fuel-powered school bus used to transport children to and from school located in the City of New York shall utilize the Best Available Retrofit Technology ("BART"), as defined in 15 RCNY § 26-01. In making their selections, persons fulfilling school bus contracts are directed to consult the EPA and CARB verified lists at http://www.epa.gov/otaq/retrofit/retroverifiedlist.htm and http://www.arb.ca.gov/diesel/verdev/background.htm. The persons fulfilling school bus contracts shall select BART for their diesel fuel-powered school buses in accordance with 15 RCNY § 26-05. Such persons shall notify the Department of their selections, and the Department shall make a determination as to whether the BART selected may be utilized for the vehicle, engine and application for which it was selected. The Department shall notify these persons of its determination.
(a) Any diesel fuel-powered school bus that is equipped with an engine certified to the applicable 2007 United States Environmental Protection Agency standard for particulate matter as set forth in § 86.007-11 of title 40 of the Code of Federal Regulations or to any subsequent United States environmental protection agency standard for such pollutant that is at least as stringent, shall not be required to utilize the BART as defined in 15 RCNY § 26-01.
(b) Any best available retrofit technology, or substantially similar technology, purchased or installed in whole or in part with funds provided by the state of New York or the federal government pursuant to a specific diesel emissions reduction program in effect upon the date of enactment of this section, shall constitute the best available retrofit technology for a period of not less than three years from the date on which such equipment was installed.
Level IV A Closed Crankcase Filtration System in combination with any Diesel Particulate Filter (DPF) or other technology verified for a specific application from either the CARB or EPA verified lists that reduces particulate matter emissions by 85 percent or greater, or reduces engine emissions to less than or equal to 0.01 grams diesel particulate matter per brake horsepower-hour.
Level III A Closed Crankcase Filtration System in combination with any DPF or Flow Through Filter or combination of technologies verified for a specific application from either the CARB or EPA verified lists that reduces diesel particulate matter emissions by between 50 and 84 percent.
Level II A Closed Crankcase Filtration System in combination with any DOC or Flow Through Filter or other technology verified for a specific application from either the CARB or EPA verified lists that reduces diesel particulate matter emissions by between 25 and 49 percent.
Level I A Closed Crankcase Filtration System in combination with any DOC or emulsified diesel fuel or Flow Through Filter or other technology verified for a specific application from either the CARB or EPA verified lists that reduces diesel particulate matter emissions by between 20 and 24 percent.
(a) For each type of school bus subject to the BART requirement, the person fulfilling a school bus contract must identify, in list form, all types of pollution control technology devices verified for such type of school bus at classification Level IV.
(b) All types of pollution control technology devices identified by such person as classification Level IV devices that are not technologically feasible for use with respect to the particular vehicle, engine or application are to be eliminated from such list. The engine model year should be considered for BART selection among different DPFs as an active filter is necessary for pre-1994 engine model years. To eliminate all types of pollution control technology devices identified by such person at classification Level IV, or a specific type of pollution control technology, or a particular pollution control technology device, such person must demonstrate to the satisfaction of the Commissioner that operational constraints or physical, chemical or engineering principles preclude the successful and effective use of the school bus when used with such types of technology devices, or type of technology, or particular pollution control technology device.
(c) If, after the elimination process, no pollution control technology devices remain in classification Level IV from which such person can select a BART, the same identification and elimination process must be done for classification Level III. If, after the elimination process, no pollution control technology devices remain in classification Level III from which such person can select a BART, the same identification and elimination process must be done for classification Level II. If, after the elimination process, no pollution control technology devices remain in classification Level II from which such person can select a BART, the same identification and elimination process must be done for classification Level I.
(d) Once a level is selected as provided for in subdivisions (a), (b), and (c) of this section, an economic impact analysis is to be performed on the remaining technologies where the technology reduces both PM and nitrogen oxide (NOx). Such person shall select the technology achieving, at a reasonable cost, the greatest reduction in NOx emissions. If the NOx emission does not meet the reasonable cost test, the technology that achieves the greatest PM reduction from the other remaining technologies must be selected.
No person fulfilling a school bus contract shall be required to replace a selected BART within three years of having first utilized such technology. Furthermore, no person fulfilling a school bus contract shall be required to replace Level IV technology until it has reached the end of its useful life.
All diesel fuel-powered school buses used to transport children to or from any school located in the City of New York must be powered by ultra low sulfur diesel fuel unless the Commissioner has issued a waiver pursuant to subdivision (g) of § 24-163.7 of the Code.
