TITLE: Docket No. 88-21; Notice No. 3; 57 FR 49413, November 2, 1992

ATTACHMT: Attached to letter dated 3/24/94 from John Womack to Gary D. March (A42; Std. 217)

TEXT:

On November 2, 1992, NHTSA published a Final Rule which revised the minimum requirements for school bus emergency exits and improved access to school bus emergency doors. I am sure you would agree that the purpose of this rulemaking was to enhance the s afety of children being transported in school buses. The Docket states that this Final Rule is effective May 2, 1994. We at the Illinois Department of Transportation interpret this Docket to mean school buses manufactured on or after May 2, 1994 must c omply with these new standards.

In September of 1993, we were asked the following question by a school bus distributor here in Illinois:

Does the vehicle's "date of manufacture" correspond to the vehicle's chassis completion date or the vehicle's body completion date? In essence, he asked when do manufacturers have to comply with this Docket?

On September 27, 1993, Ms. Catherine Allen of my staff spoke to Mr. David Elias of NHTSA and asked him the above question. He indicated the date of manufacture is correlated to the vehicle's date of completion. The vehicle's date of completion correspo nds to the date when the body and chassis are combined to form a completed vehicle. Therefore, we interpreted that answer to mean vehicles "combined" on or after May 2, 1994 must comply with this Docket.

On February 2, 1994, Ms. Allen spoke to Ms. Jane Dawson of Thomas Built Buses and asked if school buses manufactured on or after May 2, 1994 would meet the new standards. She replied, "Only if the chassis was manufactured on or after May 2, 1994." She indicated multi-stage manufacturers have the option of choosing the chassis manufacture date, the body manufacture date or a date in- between for the effective date of new standards.

On February 3, 1994, Ms. Allen spoke to Mr. Charles Hott of NHTSA and asked him the same question. He confirmed what Ms. Dawson had said.

Therefore, according to Mr. Hott's interpretation, a school bus which clearly displays a June 1994, or later, date of manufacture will not need to meet the standards of Docket 88-21 if the chassis was completed prior to May 2, 1994.

Since we have received two different interpretations from Mr. Elias and Mr. Hott, we are asking for an official interpretation from the agency. Currently, school districts are in the process of taking bids on buses that will be

delivered and perhaps have bodies mounted after May 2, 1994 to chassis manufactured prior to May 2, 1994. Therefore, I am sure you can understand the necessity of a prompt and official interpretation by your office.

If you need any additional information from us, please contact Mr. Larry Wort at 217/782-4974 or Ms. Catherine Allen at 217/785-1181. I will appreciate your expeditious response.
