ppm TDS), the mud pit will be lined so as to contain the fluids capable of contaminating surface <br />waters, soil, or vegetation. This lined pit will also be able to contain any Dissolution Surface <br />Aquifer that may be encountered during drilling operations. During all well pad construction <br />and drilling activities, a porta -potty will be present on -site for use by any individuals working on <br />the well or pad. Sewage contained within the porta -potty will be removed by way of a vacuum <br />truck weekly and at the conclusion of the drilling operations. <br />Once a well has been completed and is active in the long -term as an injection/recovery or <br />monitoring well, the well and pad have very few potential pollutant sources. Eligible well pads <br />will be interim reclaimed by recontouring, distributing topsoil, and reseeding as much as possible <br />to still allow access to the wellhead. Active injection/recovery well pads will have a pit for spill <br />containment. Wellhead integrity is to be inspected on a monthly basis as part of the monthly <br />water level /water quality sampling program. Wellhead integrity issues will be immediately <br />remediated and the faulty wellhead will be repaired appropriately. Spills resulting from a <br />ruptured wellhead will be directed toward the pit to contain the fluid. This fluid will be removed <br />by vacuum truck and disposed of at an appropriate facility. Any remaining fluid will be allowed <br />to dry, and then the contaminated soil will be removed and disposed of appropriately. In order to <br />keep monitoring wells clean and protected, plastic porta -potty covers are currently installed over <br />the monitoring wells and are to continue to be used for subsequent completed monitoring wells. <br />As noted above, silt fences or berms will exist around the perimeter of the well pad as long as it <br />is in existence to prevent erosion. <br />Well field operators are responsible for inspecting the active injection and production wells, well <br />pad, and associated pipeline once per 12 -hour shift. These inspections are documented daily, <br />and the log book detailing the inspections is stored in the NSI processing plant. <br />2.2.2.2 Pipeline <br />NSI's pipeline carries aqueous barren and pregnant liquor between the well field and the <br />processing plant. This pipeline extends across approximately 2 miles of terrain on the NSI <br />leases. <br />In order to prevent potential leaks of pregnant liquor from the pipeline, the entire pipeline trace <br />will be walked and examined monthly to identify any existing leaks or potential cracks or <br />breaches of the pipeline. If a leak is discovered, the pipeline is to be shut down until after the <br />problem can be remedied. If the spill is large enough, trenches will be dug in the vicinity of the <br />spill to contain as much of the spill as possible. Inactive sections of pipeline are to be walked <br />and inspected annually. Sections that are compromised and have scale exposed to stormwater <br />are to be removed and either disposed of or amended for future use. As noted in Section 2.2.2.1 <br />above, operators are required to inspect the pipeline in the vicinity of an active injection or <br />recovery well pad once per 12 -hour shift. Additionally, 250 gallon totes are placed near <br />wellheads to contain potential minor leaks. <br />Daub & Associates, Inc. NSI 2011 SWMP <br />Page 9 <br />
