In the matter of
International Uranium (USA) Corporation Sunday Mine Complex
l.D. No. 05-01197
Petition for Modification
Docket No. M-98-08-M

Proposed Decision and Order on Petition for Modification Background

On December 28, 1998, The International Uranium (USA) Corporation filed a petition for modification of 30 CFR §57.14130(a)(4), roll-over protective structures (ROPS) and seat belts for surface equipment, to petitioner's Sunday Mine Complex, (1.D. No. 05-01197), located in Dolores County, Colorado. The mine is an underground uranium operation using the stope and cross-cut method to recover the ore.

The relevant standard 30 CFR §57.14130, roll-over protective structures (ROPS) and seat belts, provides:

(a) Equipment included. Roll-over protective structures (ROPS) and seat belts shall be installed on-----­

(4) The tractor portion of semi-mounted scrapers, dumpers, water wagons, bottom-dump wagons, rear-dump wagons, and towed fifth wheel attachments;

The Petitioner uses Elmac semi-mounted dumpers to haul material in the underground sections of its mine. This equipment is also driven out of the portal and operated at the surface areas of the mine. The petitioner has proposed implementing traffic procedures in lieu of providing articulated semi-mounted dumpers with seat belts and rollover protection. The petitioner has proposed restricting the speed of the trucks to five miles per hour and demarcating the surface area traveled by the trucks as a "no travel zone" for unauthorized surface mining equipment. The petitioner also proposed requiring these haul unit operators to come to a "rolling stop" when exiting the mine portal, and visually survey the travel route before proceeding. The petitioner alleged that the proposed alternative method of implementing traffic controls instead of installing (ROPS) and seat belts on the haulage units would provide protection equal to the standard.

On March 17, 1999, MSHA investigators conducted an investigation relevant to the merits of the petition and filed a report of their findings and recommendations with the Administrator for Metal and Nonmetal Mine Safety and Health. After a careful review of the entire record, including the petition and MSHA's investigative report and recommendations, this Proposed Decision and Order is issued.

Findings of Fact and Conclusion of Law

30 CFR §57.14130(a)(4) requires that ROPS and seat belts be installed on specific mobile equipment. The petitioner asserts that the ROPS and seat belts are not necessary since the haulage units travel in areas that are completely flat and free of obstacles. The investigation revealed that the haulage units had been operated on a stockpile of low grade material with an elevated road of approximately 18% grade. The petition did not address the travel on this stockpile. The superintendent stated that the haulage units would dump at the toe of the pile.

Additionally, the petitioner asserted that by reducing the speed of the haulage units to 5mph, demarcating the area traveled by the trucks as a "no travel zone," and coming to a "rolling stop" exiting the mine, would eliminate the potential for a collision or rollover type accident. The petitioner's use of the proposed traffic controls does not offer the same level of protection as the ROPS and seat belts. The engineered protections to the miners as compliance with the standard.
