Environmental Policies and Procedures
Mammoth Resource Partners’ commitment to environmental safety is expressed through its field policies, which are designed to minimize its environmental impact.
- Drill pads - Prior to drilling, raw land must be excavated into a usable drill pad. Mammoth’s knowledge of the formations into which it drills allow its crews to minimize the amount of land cleared for drill operations. A typical drill pad will measure approximately 200 by 200 feet, or about 9/10's of an acre. Mammoth has used drill pads as small as 50 by 50 feet when possible.
- Erosion and sediment control - During excavation of sites, Mammoth utilizes an array of erosion and sediment control devices. Culverts, silt fences, break dams, and ditches control surface water runoff, and prevent sediment from escaping the site. Proper planning helps Mammoth employ these measures so as to limit the effect its drilling activities has on the environment.
- Well spacing - All wells are spaced at a minimum 1,000 feet offset from another well. This minimizes surface impact by disturbing only a small amount of the available land. If Mammoth crews find two or more production zones, they have the potential to use the same well pad to drill a second "twin" well, as opposed to creating a new location.
- Protecting fresh water zones - When drilling an oil or gas well, inevitably fresh water will be encountered. When fresh water is found, casing is set into the well bore. Concrete is circulated down the casing string so that it pushes up between the outside of the casing and the well bore. This concrete holds the casing in place, and prevents water from entering the well or hydrocarbons from being released into the fresh water zone.
- Produced water - Generally, an oil or gas well will produce a certain amount of fresh or brine water. These fluids are collectively known as produced water. Produced water contains trace amounts of hydrocarbons and minerals, and is considered hazardous waste. Mammoth stores produced water in holding tanks until it can be picked up by an approved transporter and taken off-site for disposal.
- Land reclamation - After drilling and stimulation are complete, land surrounding the well site that will not be needed for daily operations are limed, reseeded, and mulched. This prevents erosion from the drill pad. Proper reclamation of drill sites also allows wildlife to naturally re-introduce to disturbed areas.
- Spill prevention - Each site is part of a spill prevention, control and countermeasure plan (SPCC) that is certified by an engineering firm. The SPCC outlines measures that are taken to prevent spills, such as outlining inspection, maintenance, and training schedules; controlling spills through the use of remote impoundments or berms around storage facilities; and steps that will be taken in the event of an accidental discharge.

Famous quotes containing the words policies and/or procedures:
“... [Washington] is always an entertaining spectacle. Look at it now. The present President has the name of Roosevelt, marked facial resemblance to Wilson, and no perceptible aversion, to say the least, to many of the policies of Bryan. The New Deal, which at times seems more like a pack of cards thrown helter skelter, some face up, some face down, and then snatched in a free-for-all by the players, than it does like a regular deal, is going on before our interested, if puzzled eyes.”
—Alice Roosevelt Longworth (1884–1980)
“Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.”
—David Elkind (20th century)
