Disposal of Drill Cuttings

The disposal of drill cuttings is truly a broad and expansive subject matter. This is so much the case that any basic evaluation of its components is sure to omit many aspects. However, several consistencies do occur despite locale and jurisdiction. These include awareness of erosion potential, local water sources, soil contaminants and the proper method for refilling bore holes with the drill cuttings. Proper disposal will rest upon your acquaintance and compliance with specific state laws.

Instructions

• 1

  Research state laws. This is a process which will be variable given state legal context. Each jurisdiction may offer slightly different procedures or protocols given their respective legislation. The best thing you can do is contact your state department of environmental protection via phone or e-mail in order to inquire as to proper procedure.

• 2

  Replace the mud or cuttings in the bore hole. This is one possibility, yet be aware of restrictions as to this practice. The state of New York allows you to refill the bore hole if there is no pierced well, aquitard or aquiclude present. The fill must not allow contaminants to seep vertically into the space and compacted soil must be used to cover the bore hole once the procedure is finished.

• 3

  Measure out distances from water. You may be able to designate your own disposal area for the cuttings. This may also be subject to state prohibitions related to nearby water sources. Pennsylvania requires the site to be at least 100 feet away from any creek, wetland or stream. It must be at least 200 feet away from any other recognizable water supply.

• 4

  Introduce soil additives. In the event that you are refilling an existing bore hole, you may be instructed to use a soil additive in order to reduce the permeability of the drill cuttings. New York lists the additive bentonite as a primary option.

• 5

  Level off the site. You may be required to use your heavy machinery to level the refilled bore hole so erosion and other elements will not encourage run off.

• 6

  Ensure the absence of polluting materials. This may be done through either onsite chemical testing or through an accredited lab. Such pollutants to watch out for include but are not limited to brines, drilling muds, stimulation fluids, oil, production and drilling fluids other than tophole water, fresh water or gases.
