These standards apply to the following affected facilities in fixed or portable nonmetallic mineral processing plants: each crusher, grinding mill, screening operation, bucket elevator, belt conveyor, bagging operation, storage bin, and enclosed truck or railcar loading station, which commenced construction, modification or reconstruction after August 31, 1983. Also, crushers and grinding mills at hot mix asphalt facilities that reduce the size of nonmetallic minerals embedded in recycled asphalt pavement and subsequent affected facilities up to, but not including, the first storage silo or bin are subject to the provisions of the subpart. The provisions of this subpart do not apply to the following operations: all facilities located in underground mines; wet material processing operations; and plants without crushers or grinding mills. An affected facility that is subject to the provisions of subparts F or I or that follows in the process any facility subject to the provisions of subparts F or I of this part is not subject to the provisions of this part. In addition the following plants are not subject to this subpart: fixed sand and gravel plants and crushed stone plants with capacities of 23 megagrams per hour (25 tons per hour) or less; portable sand and gravel plants and crushed stone plants with capacities of 136 megagrams per hour (150 tons per hour) or less; common clay plants and pumice plants with capacities of 9 megagrams per hour (10 tons per hour) or less.
The change in burden cost from the most recently approved ICR is due to seven reasons. First, the number of NMPP projected to become subject to subpart OOO in the next 3 years is smaller than the previously approved ICR. Second, the 60.7(a)(1) notification of construction/reconstruction commencement is being eliminated for subpart OOO facilities. Third, new standards in subpart OOO require additional monitoring requirements. Fourth, a greater number of existing NMPP are now subject to subpart OOO. Fifth, the revised analysis for this ICR includes time for management and clerical workers as well as technical staff. Sixth, the hourly labor rate increased from $57.12 per hour to $90.96 per hour. Seventh, performance testing was calculated as a capital cost because it is likely to be conducted by a contractor. Overall, these changes result in a decrease in hourly burden and an increase in capital costs from the most recently approved ICR.
