Discuss, consider, and take appropriate action on the LONO Exhibit between Williamson County and Atmos Energy Corporation in relation to the Line P(2nd) (30” Steel Gas Pipeline) and Line P (South) (20” Steel Gas Pipeline).
Background
Atmos Energy has determined that the design for the proposed roadway pavement improvements, consisting of three (3) 12’ wide travel lanes with 4’-4.5’ wide concrete shoulders and a 10’ wide concrete shared use path, will not present a significant conflict provided that this letter is executed and returned prior to the commencement of the construction and the following additional criteria are followed:
During Construction:
1. Based on previously provided construction equipment loads and stress analysis, a timber matting air-bridge per Atmos Standard 11-100-00 shall be utilized for any construction equipment crossing prior to the installation of the above-referenced road/street and protective slab. There must be an air gap over the designated crossing locations for the construction equipment to cross. At no time shall construction equipment be allowed to travel parallel with the right-of-way, directly over the top of any Atmos pipeline.
2. A minimum of 4.22 feet for Atmos Energy’s Line P(2nd) (30” Steel Gas Pipeline) and 3.38 feet for Atmos Energy’s Line P(South) (20” Steel Gas Pipeline) of existing cover shall be maintained over the existing Atmos Energy facilities where construction vehicle crossings will occur prior to the construction of the proposed roadway pavement improvements for Williamson County.
3. No medium-to-large vibratory compaction equipment is allowed within a minimum of 10 feet of the pipeline(s). Only walk-behind vibratory rollers / compactors are allowed.
