EPA reviews states’ solid waste management regulations for oil and gas operations

In an April 1, 2014 memorandum, the U.S. Environmental Protection Agency (EPA) summarized state regulatory programs concerning the management of solid waste from oil and natural gas exploration, development and production (E&P) operations.

In reviewing each state’s regulations, the EPA focused on surface storage and disposal facilities managing produced waters, drilling muds, drilling cuttings, hydraulic fracturing return fluids, and various other waste liquids and materials intrinsically related to oil and gas E&P.

The EPA found that the state regulations were primarily concerned with the “technical requirements associated with the design, construction, operation, maintenance, closure, and reclamation of surface pits, … Continue Reading

Montana disclosure regulations, effective August 26, 2011

In Montana, before a well can be hydraulically fractured, acidized, or chemically treated, either in the drilling permit application or in a notice of intent to stimulate a well, the owner, operator, or service company must fully describe the activity by providing:

  • the estimated total volume of treatment to be used;
  • the trade name or generic name of the principle components or chemicals;
  • the estimated amount of the principal components such as viscosifiers, acids, or gelling agents;
  • the estimated weight or volume of inert substances such as proppants; and
  • the maximum anticipated treating pressure or a written description of the

USGS assesses undiscovered oil resources in Bakken and Three Forks Formations

The U.S. Geological Survey (USGS) recently completed a geology-based assessment of the oil and gas resources of the Bakken and Three Forks Formations, located in North Dakota, Montana, and South Dakota, finding that these formations together hold an estimated mean of 7.38 billion barrels of oil, 6.7 trillion cubic feet (tcf) of gas, and 0.53 billion barrels of natural gas liquids. See USGS Fact Sheet 2013–3013: Assessment of Undiscovered Oil Resources in the Bakken and Three Forks Formations, Williston Basin Province, Montana, North Dakota, and South Dakota, 2013. The Three Forks Formation was found to have 3.73 billion barrels … Continue Reading

Texas, Other States Move Forward With Hydraulic Fracturing Disclosure Regulations

Earlier this year, Texas became the latest state to draft regulations requiring the disclosure of chemicals used in the hydraulic fracturing process. Michigan and Montana issued similar regulations over the summer, joining Arkansas, Wyoming, and Pennsylvania as states recently active in regulating hydraulic fracturing.[1] The new regulations require specific disclosures by operators and outline requirements for construction and operation of the well and continued monitoring of well activity. Three additional states, Louisiana, New York, and North Dakota, have proposed regulations open for public comment. This briefing examines recent changes and additions in hydraulic fracturing regulations throughout the country.

Texas: Public
