          - [Docket No. NHTSA-2001-8827; Notice 1]

                    We are asking for comments on the application by Dan Hill & Associates, Inc. (“Dan Hill”), of Norman, Oklahoma, for an exemption of one year from Motor Vehicle Safety Standard No. 224                     *Rear Impact Protection.*                     Dan Hill asserts that compliance would cause substantial economic hardship to a manufacturer that has tried in good faith to comply with the standard.                 

We are publishing this notice of receipt of the application in accordance with our regulations on the subject. This action does not mean that we have made a judgment yet about the merits of the application. 

Dan Hill has been the beneficiary of temporary exemptions from Standard No. 224 beginning on January 26, 1998 (see 63 FR 3784 and 64 FR 49047). The information below is based on material from Dan Hill's original and renewal applications of 1998 and 1999, and its most recent application of 2000. 

## Why Dan Hill Says That it Continues To Need an Exemption

Dan Hill manufactures and sells a horizontal discharge trailer (“Flow Boy”) that is used in the road construction industry to deliver asphalt and other road building materials to the construction site. The Flow Boy is designed to connect with and latch onto various paving machines (“pavers”). The Flow Boy, with its hydraulically controlled horizontal discharge system, discharges hot mix asphalt at a controlled rate into a paver which overlays the road surface with asphalt material. 

                    Standard No. 224 requires, effective January 26, 1998, that all trailers with a GVWR of 4536 Kg or more, including Flow Boy trailers, be fitted with a rear impact guard that conforms to Standard No. 223                     *Rear impact guards.*                     Dan Hill argued that installation of the rear impact guard will prevent the Flow Boy from connecting to the paver. Thus, Flow Boy trailers will no longer be functional. Paving contractors will be forced to use either competitors' horizontal discharge trailers that comply with Standard No. 224 or standard dump body trucks or trailers which, according to Dan Hill, have inherent limitations and safety risks. In spite of                           ( print page 10051)                        exemptions totaling three years, Dan Hill avers that it has been unable to engineer its trailers to conform and needs a further year in which to do so. We discuss below its efforts to conform in greater detail.                 

## Dan Hill's Reasons Why it Believes That Compliance Would Cause it Substantial Economic Hardship and That it Has Tried in Good Faith To Comply With Standard No. 224

Dan Hill is a small volume manufacturer. Its total production in the 12-month period preceding its latest petition was 151 units. In the absence of a further exemption, Dan Hill asserts that approximately 70 percent of its work force would have to be laid off. If the exemption were not renewed, Dan Hill's gross sales would decrease by $8,313,337 in 2001. Its cumulative net income after taxes for the fiscal years 1998, 1999, and 2000 was $454,556, but net income has declined in 2000 and 1999 from the year before. It projects a net loss of $291,947 for fiscal year 2001. 

                    The                     **Federal Register**                     notices cited above contain Dan Hill's arguments of its previous good faith efforts to conform with Standard No. 224 and form the basis of our previous grants of Dan Hill's petitions. Dan Hill originally asked for a year's exemption in order to explore the feasibility of a rear impact guard that would allow the Flow Boy trailer to connect to a conventional paver. It concentrated its efforts between 1998 and 1999 in investigating the feasibility of a retractable rear impact guard, which would enable Flow Boys to continue to connect to pavers. The company has examined the various alternatives: installation of a fixed rear impact guard, redesign of pavers, installation of a removable rear impact guard, installation of a retractable rear impact guard, and installation of a “swing-up” style tailgate with an attached bumper. Its latest efforts to conform, from September 1999 until December 2000, involve the design of a swing-in retractable rear impact guard. A review of its design, by Tech, Inc., shows that this, too, is not feasible. Among other things, Tech, Inc., is concerned that “the tailgate, hinges, and air cylinders will not meet the criteria of the Standard 224-plasticity requirement,” and that “the bumper is a potential safety hazard” because if the gate were raised and “a flagman or a trailer stager is in between the paver and the bumper while the gate and bumper is rising, the bumper could cause serious injury or death.” A copy of Tech Inc.'s report has been filed in the docket as part of Dan Hill's petition. The report also indicates that the costs associated with this design may be cost prohibitive “when trying to win business in a highly competitive, yet narrow marketplace.”                 

## Dan Hill's Reasons Why it Believes That a Temporary Exemption Would Be in the Public Interest and Consistent With Objectives of Motor Vehicle Safety

Dan Hill believes that an exemption would be in the public interest and consistent with traffic safety objectives because, without an exemption, “within a short time, production of the trailer will cease entirely. Jobs will be lost and a major employer in McClain County will be lost. This would mean a significant loss to many people in the state, including shareholders, lenders, employees, families, and other stakeholders.” Dan Hill's production represents less than .05% of trailers manufactured. The amount of time actually spent on the road is limited because of the need to move the asphalt to the job site before it hardens. Nevertheless, Dan Hill has taken recent efforts to enhance the conspicuity of Flow Boy trailers by: 1. adding “High intensity flashing safety lights; 2. Doubling the legally required amount of conspicuity taping at the rear of the trailer; 3. [adding] Safety signage; 4. [adding] Red clearance lights that normally emit light in twilight or night-time conditions; and 5. Installation of a rear under-ride protection assembly 28″ above the ground and 60″ in width.” Finally, the location of the rear tires is such that the tires act as a buffer “and reduce the likelihood of impact with the semi-trailer and the vehicle's windshield or interior of the vehicle significantly.”
