35 CSR 8 – Rule Governing the Development of Horizontal Wells – This is a new rule, necessitated by the passage of HB 401 on December 14, 2011. OOG has taken the applicable sections of the existing rule governing conventional oil and natural gas wells (35 CSR 4 – Oil and Gas Wells and Other Wells) and transferred them to this new rule, and further expanded on the new Natural Gas Horizontal Well Control Act in the following areas: erosion and sediment control plan; site construction plan; water management plan; well site safety plan; casing and cementing standards; well records, including records and disclosure of chemicals used in the hydraulic fracturing process; water supply testing; and construction standards for large wastewater pits and freshwater impoundments.
