Notice of Final Action

The EPA approved three Requests for Coverage under the SQCS General Permit ^[1] submitted by the Permittees. The Requests for Coverage under the SQCS General Permit were approved on the dates listed in Table 1. These approvals pertain to the construction and operation of the Sources, all of which are or were stationary and portable stone quarrying, rock crushing, and screening plants, located in Indian Country. The EPA issued the approvals pursuant to the provisions of Clean Air Act sections 110(a) and 301(d) and the EPA's Tribal Minor NSR Program at 40 CFR 49.151 through 49.165. The EPA based its approvals on its determinations that the Sources met the criteria qualifying them for coverage and that the Sources were eligible for coverage under the SQCS General Permit.
