The proposed project will require the modification of the pre-existing natural gas pipeline to accommodate in-line inspection devices, known as “smart pigs”, to maintain compliance with U.S. Department of Transportation Pipeline Hazardous Materials Safety Administration pipeline safety regulations. The proposed project activities will involve the excavation of a segment of pre-existing Amarillo No. 2 pipeline, dewatering of the excavation, temporary storage of spoil stockpile, removal of the existing receivers, valve replacement or addition, and changing out of tees. These proposed construction activities will occur within the Muscatine Island Levee District’s Right-of-Way. The proposed project workspace limits within levee right-of-way will be approximately 2.71 acres.
