Open trench requires less time of disturbance to the environment. HDD takes roughly 10 months to complete where an open cut of this size crossing is less than a week. Open trench method requires less workspace than HDDs which require large workspace areas at the entry and exit locations. Specifically at the Neuse River additional 'false ROW' for the environmental disturbance). HDD for a 36 -in diameter pipeline 1800 -ft from entry to exit hole.

A trenchless construction method of installing pipeline segments beneath surface features Avoids surface disturbance between the entry and exit points of the HDD A small -diameter pilot hole is drilled along a predetermined path (continuously steered and monitored) Progressively larger reaming tools are retrieved through the pilot hole to achieve the desired diameter What is an HDD? (cont'd) Mixture of water and bentonite clay is used to lubricate the bit, transport cuttings, and maintain the integrity of the hole. The prefabricated length of pipe is pulled through the drill path to the entry side of the HDD. The pull section will be inspected and hydrostatically tested prior to installation Each end of the HDD will be tied in to the remaining pipeline using traditional pipeline construction methods.

IDENTIFICATION ACP is identifying all wells within 150 -ft of the limits of disturbance (LOD) as required by the Federal Energy Regulatory Commission (FERC) and the Code of Federal Regulations. In addition, ACP is identifying wells within 500 -ft of the centerline in Karst areas and within 0.25 miles (1320 -ft) of horizontal directional drill (HDD) entry/exit locations. Well identification and testing are voluntary. Landowners are advised these tests are to their benefit and will provide a baseline output and water quality prior to construction. Atianticl Coast PipeUne I ACP — Well Testing Parameters Water samples are tested for: pHI Total Suspended Solids, Total Dissolved Solids, Conductivity, alkalinity, acidity, sulfates, oil/grease, fecal coliform, phenolic, iron, manganese, aluminum, copper, lead, nickel, silver, thallium, zinc, chromium, arsenic, mercury, selenium, cyanide, calcium magnesium, hardness, chlorides, antimony, cadmium, and beryllium. ACP - Water Source Testing Prior to beginning construction four tests are conducted; one per season: Winter —October to December Spring —January to March Summer — April to June Fall —July to September Well identification and test consists of: Well output/flow Water quality Coordinates of the well Atlantic will not be conducting post construction testing unless a land owner makes a claim.
