2013 Case-by-Case Determinations


Reference:  #2013-SB03
Request:  For Eureka City Schools (a unified school district) Bus #10 (Vehicle Identification Number 1BABNBMA8YF092146), allow compressed natural gas tanks to be replaced before the school bus is 14 years old. 

Air District:  North Coast Unified Air Quality Management District
Guidelines Section(s):  Mail-Out #MSC 11-37
Determination:  Mail-Out #MSC 11-37 requires school buses to be at least 14 years old, but no older than 16 years, to receive Assembly Bill 923 funding for compressed natural gas tank replacement.  Bus #10 is a 2000 model year vehicle.  Because the compressed natural gas tanks are not currently accessible for photography, the school district used visual observations to determine that all four of the bus’s compressed natural gas tanks have an August 2014 expiration date (in such cases, for documentation, the school district will submit photographs of the compressed natural gas tanks after the tanks are removed). 

The school district, which is in Eureka, would like to replace Bus #10’s compressed natural gas tanks during July or August of 2013 – about four to five months before the bus will be 14 years old.  In the request, the school district indicated that 1) the nearest vendor that is authorized to replace the compressed natural gas tanks is A-Z Bus Sales in Sacramento (a round trip from Eureka to Sacramento is approximately 600 miles); 2) A-Z Bus Sales is also the nearest vendor to repair and work on John Deere compressed natural gas engines; and 3) the John Deere engine in Bus #10 is experiencing mechanical issues and they plan to send it to Sacramento for service this summer.  The school district estimates that it would save approximately $1,250 by having the compressed natural gas tanks replaced at the same time the engine is serviced during one trip from Eureka to Sacramento in July or August of 2013, as opposed to making two trips to Sacramento – one in July or August of 2013 to service the engine, and another one to replace the compressed natural gas tanks in 2014 after the bus is 14 years old.

The air district did not indicate that it will need the ability to proceed with this project prior to the bus reaching 14 years old in order to ensure tank replacement prior to the tank expiration date.

Air Resources Board Action:  Not approved.

Reference:  #2013-SB02
Request:  Allow Lower-Emission School Bus Program funding within the $20,000 retrofit funding cap to be used for Oak Grove School District to purchase two spare diesel particulate filters (each spare filter for a different type of retrofit device).
Air District:  Bay Area Air Quality Management District
Guidelines Section(s):  Chapter IV, Section C

Determination:  The air district is in the process of awarding funds to Oak Grove School District for the installation of 17 retrofit devices.  Thirteen buses (numbers 19, 20, 21, 22, 23, 24, 25, 28, 29, 30, 31, 32, and 46) will receive Donaldson LNF retrofit devices, and four buses (numbers 36, 38, 39, and 40) will receive Donaldson LXF retrofit devices.  Different retrofit devices will be used because the applicability of a Donaldson LNF or LXF is partially determined by the model year of the engine and whether the engine is high or low NOx.

Having a spare filter minimizes the disruption to a school district’s normal fleet operation during filter maintenance intervals for a bus.  The Lower-Emission School Bus Program Guidelines only allow funds to pay for one spare filter for up to 20 in-service retrofits.  Because two different types of retrofit devices will be used, the school district would like to use Lower-Emission School Bus Program funds to purchase two spare filters -- one for the Donaldson LNF retrofit devices and one for the Donaldson LXF retrofit devices.  This request is consistent with the intent of the Lower-Emission School Bus Program Guidelines to minimize disruption in the school districts’ ability to provide transportation to students.

ARB Action:  Approved for funding with AB 923 funds.
Determination Date:  June 17, 2013

Reference:  #2013-SB01

Request: The air district is requesting an exemption from the requirement for a school bus to be at least 14 years old to be eligible for a compressed natural gas tank replacement for the following three school buses that belong to the Lompoc Unified School District:

VIN
1T75U4F21Y1078418
1T75U4F2XY1078420
1T75U4F2XY1078417

Air District: Santa Barbara County Air Pollution Control District
Guidelines Section(s): Mail-Out #MSC 11-37
Determination: Mail-Out #MSC 11-37 requires school buses to be at least 14 years old, but no older than 16 years, to receive funding.  All of the school buses listed in this request are 2000 model year vehicles.   The documentation provided shows that each bus has some tanks that will expire in late 2013 (October 2013 for one bus and December 2013 for the other two buses) and some tanks that will expire in February 2014.  In order to ensure tank replacement prior to expiration, the air district will need the ability to execute contracts and proceed with projects prior to the buses reaching 14 years of age. 

ARB Action: Approved for funding with AB 923 funds.
Determination Date: April 10, 2013
