Parts and Accessories Necessary for Safe Operation, Lamps and Reflective Devices; Application for an Exemption From STEMCO LP

AGENCY: Federal Motor Carrier Safety Administration (FMCSA), DOT.

ACTION: Notice of application for exemption; request for comments.

-----------------------------------------------------------------------

SUMMARY: FMCSA requests public comment on an application for exemption from STEMCO LP (STEMCO) to allow motor carriers to operate commercial motor vehicles (CMVs) that are equipped with STEMCO's TrailerTailsupreg aerodynamic device with rear identification lamps and rear clearance lamps that are mounted lower than currently permitted by the Agency's regulations. The Federal Motor Carrier Safety Regulations (FMCSRs) require rear identification lamps and rear clearance lamps to be located ``as close as practicable to the top of the vehicle.'' While the TrailerTailsupreg aerodynamic device is currently mounted slightly below the roof of the vehicle, STEMCO states that this offset prevents the device from delivering the maximum available fuel economy benefit as opposed to mounting it flush with the top of the vehicle which may block the visibility of the rear identification lamps and rear clearance lamps. STEMCO believes that locating the rear identification lamps and rear clearance lamps lower on the vehicle, on a horizontal plane with other required lamps (stop, turn, and tail lamps) as is done on a flatbed trailer or an intermodal chassis, will maintain a level of safety that is equivalent to, or greater than, the level of safety achieved without the exemption. STEMCO is requesting the temporary exemption in advance of petitioning FMCSA to conduct a rulemaking to amend 49 CFR 393.11.

SUPPLEMENTARY INFORMATION:

Background

Section 4007 of the Transportation Equity Act for the 21st Century (TEA- 21) Pub. L. 105-178, June 9, 1998, 112 Stat. 401 amended 49 U.S.C. 31315 and 31136(e) to provide authority to grant exemptions from the Federal Motor Carrier Safety Regulations (FMCSRs). On August 20, 2004, FMCSA published a final rule (69 FR 51589) implementing section 4007. Under this rule, FMCSA must publish a notice of each exemption request in the Federal Register (49 CFR 381.315(a)). The Agency must provide the public with an opportunity to inspect the information relevant to the application, including any safety analyses that have been conducted. The Agency must also provide an opportunity for public comment on the request.

The Agency reviews the safety analyses and the public comments and determines whether granting the exemption would likely achieve a level of safety equivalent to or greater than the level that would be achieved by the current regulation (49 CFR 381.305).

The decision of the Agency must be published in the Federal Register (49 CFR 381.315(b)). If the Agency denies the request, it must state the reason for doing so. If the decision is to grant the exemption, the notice must specify the person or class of persons receiving the exemption and the regulatory provision or provisions from which an exemption is granted. The notice must specify the effective period of the exemption (up to 5 years) and explain the terms and conditions of the exemption. The exemption may be renewed (49 CFR 381.315(c) and 49 CFR 381.300(b)).

STEMCO Application for Exemption

STEMCO, on behalf of motor carriers utilizing its TrailerTailsupreg aerodynamic devices, applied for an exemption from 49 CFR 393.11 to allow rear identification lamps and rear clearance lamps to be mounted lower than currently permitted by the Agency's regulations. A copy of the application is included in the docket referenced at the beginning of this notice.

Table 1 of Sec. 393.11, ``Required lamps and reflectors on commercial motor vehicles,'' specifies the requirements for lamps, reflective devices and associated equipment by the type of CMV. All CMVs manufactured on or after December 25, 1968, must, at a minimum, meet the applicable requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108, ``Lamps, reflective devices, and associated equipment,'' in effect at the time of manufacture of the vehicle. Rear identification lamps must be mounted as close as practicable to the top of the vehicle. One lamp must be as close as practicable to the vertical centerline and one on each side of the center lamp with the lamp centers spaced not less than 6 inches or more than 12 inches apart, and all on the same level. One rear clearance lamp must be located on each side of the vertical centerline of the vehicle to indicate overall width, both of which must be on the same level and as high as practicable.

The U.S. Environmental Protection Agency (EPA) and the Department of Transportation's National Highway Traffic Safety Administration (NHTSA) have jointly proposed a national program that would establish the next phase of greenhouse gas (GHG) emissions and fuel efficiency standards for medium- and heavy-duty vehicles. This ``Phase 2 program'' would significantly reduce carbon emissions and improve the fuel efficiency of heavy-duty vehicles, helping to address the challenges of global climate change and energy security. In February 2015, STEMCO purchased ATDynamics and its TrailerTailsupreg product line, a collapsible boat tail technology that improves the rear aerodynamic shape of CMVs. STEMCO states that motor carriers are evaluating the TrailerTailsupreg rear aerodynamic device to help meet (1) the proposed Phase 2 program standards, and (2) the California Air Resources Board (CARB) Tractor-Trailer Greenhouse Gas Regulation for dry van and refrigerated van type trailers that has been in effect since 2010.

For newly manufactured trailers, STEMCO states that the TrailerTailsupreg top panel is mounted 1.5--3.5 inches below the roof of the trailer in order to comply with the FMVSS No. 108 and FMCSR mounting location requirements for rear identification and clearance lamps. However, STEMCO states:

This inset creates an unaeordynamic gap as airflow transitions from the trailer roof onto the TrailerTail panels and has prevented TrailerTails from delivering the maximum available fuel economy benefit. Wind tunnel flow visualization highlights the contrast in airflow between flush and inset panels and our own internal testing estimates an additional 0.14 delta CDA (measured drag area) gain and 70 million gallons of annual diesel fuel savings can be achieved simply by installing TrailerTails flush with the trailer roof. In order to evaluate the actual performance of flush mounted TrailerTail aerodynamic systems on actual fleet based fuel economy, it is necessary to request relief from the location requirements for upper identification lamps and rear clearance lamps on commercial van trailers and box trucks. Additionally, these lower clearance and identification lamp locations will pave the way for the commercial launch of collapsible boat tails for roll door box trailers, where the rear upper header is a critical mounting location of boat tail components.

In support of its application, STEMCO states that ``The relocation of the rear identification lamps and rear clearance lamps to a lower location on the trailer or box truck are equivalent to the current required lamp location on a flatbed trailer or intermodal chassis, so no safety impact is anticipated.'' In addition, according to the application:

STEMCO believes that there will be no safety impact from the relocation of both the rear identification lamps and the rear clearance lamps to a location on an approximate horizontal plane with other rear lamps. NHTSA issued legal interpretations from 1968 until approximately 1999 to trailer manufacturers to allow the lower mounting location for rear identification lamps and rear clearance lamps when there was no ``practicable'' means of installing the lamps ``as close as practicable to the top of the vehicle.'' NHTSA subsequently issued an interpretative rule on April 5, 1999, 64 FR 16358, suggesting that trailer manufacturers could no longer mount lamps at the lower location as narrow lamps were now readily available, and NHTSA would no longer defer to a manufacturer's subjective determination of practicability for locating lamps in the rear upper header location on van trailers and box trucks. However, NHTSA noted in that same Notice that they did not intend to bring enforcement actions based on this interpretive rule immediately. Subsequently, trailer manufacturers continued to manufacture van trailers and box trucks with the rear identification lamps and rear clearance lamps mounted lower on the vehicles on an approximate horizontal plane with the other required lamps.''

STEMCO states that without the exemption, it will be unable to verify fleet performance of a higher performance TrailerTailsupreg design that is expected to provide the maximum available fuel economy benefit that may

be necessary in order to meet future fuel efficiency requirements.
