Missouri Code of State Regulations › Title 10 - DEPARTMENT OF NATURAL RESOURCES › Division 50 - Oil and Gas Council › Chapter 2 - Oil and Gas Drilling and Production › Section 10 CSR 50-2.100 - Enhanced Recovery Projects

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: Enhanced recovery projects utilize fluids,
				  including but not limited to, produced water, steam, or natural gas, by
				  injection into an oil reservoir to recover additional oil. Where the oil is
				  difficult to recover with water or steam, certain chemicals are often added to
				  increase the efficiency of water as an oil-recovery agent. These enhanced
				  recovery methods help maintain reservoir pressure and increase the ultimate
				  amount of oil that can be obtained from a particular pool, thereby preventing
				  the waste of natural resources. This rule provides for the protection of
				  groundwater by requiring approval by the state geologist of certain details of
				  the enhanced recovery project . In addition, this rule protects the correlative
				  rights of the offset property owners by requiring the state geologist's
				  approval of well spacing and production unit line requirements prior to the
				  commencement of operations.
Enhanced recovery
				  projects designed for the secondary or tertiary recovery of oil or gas may be
				  approved as part of a proposed production unit. Production unit approval may be
				  requested by submitting to the state geologist an application specifying all
				  pertinent details of the proposed project as detailed in 10 CSR
				  50-3.020(2).

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: The development of gas storage operations
				  requires that they be addressed by the state. This rule will ensure protection
				  of underground sources of drinking water.
(1) Gas storage operations that inject gas
				that is liquid at standard temperature and pressure to be recovered at a later
				date for use shall comply with all rules pertaining to injection wells, except
				that such wells may not be drilled closer than approximately three hundred
				thirty feet (330') from the boundary of the gas storage operation.

					 Revised Statutes.
Missouri Code of State Regulations › Title 10 - DEPARTMENT OF NATURAL RESOURCES › Division 50 - Oil and Gas Council › Chapter 3 - Well Spacing for Oil and Gas Pools › Section 10 CSR 50-3.020 - Production Units and Well Spacing for Enhanced Recovery

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: Production units are small- to large-scale
				  projects designed to maximize ultimate recovery of oil and gas from the
				  entirety of a single pool or particular portion thereof through enhanced
				  recovery. Enhanced recovery typically involves the use of injection
				  wells.
(1) No well,
				including, but not limited to, those used for production or injection, drilled
				within a production unit shall be drilled nearer than one hundred sixty-five
				feet (165') from the production unit boundary. Stratigraphic test wells are
				exempt from this requirement.
(2)
				An operator may submit to the state geologist an application for the
				implementation of a production unit of a specified size and shape, with a well
				configuration of a certain nature of operation, for the purpose of an enhanced
				recovery project designed to maximize the ultimate recovery of oil or gas or
				both from the entirety of a single pool or particular portion thereof. The
				state geologist may approve the application if the proposed production unit is
				operated by a single operator or owner. If the proposed production unit
				includes more than one operator or owner, application shall be made to the
				council, according to procedures in 10 CSR 50-4.020. Any applicant for a
				production unit shall provide a description of the proposed production unit
				area, including the following information:
(A) Maps that show the unit boundary,
				cultural and natural surface features, areal extent of the pool, depth and
				thickness of the pool, location of any and all prior wells regardless of kind
				in the proposed unit area and those that occur within a one-half (1/2)
				mile-wide buffer area around the proposed unit;
(B) Location of all owner tracts;
(C) Location and pattern of all proposed
				production, injection, water supply and disposal wells that are to be drilled
				and operated for purpose of the proposed production unit; and
(D) Location of all surface facilities
				associated with the proposed production unit.
Missouri Code of State Regulations › Title 10 - DEPARTMENT OF NATURAL RESOURCES › Division 50 - Oil and Gas Council › Chapter 4 - Authorization of Pooling Units and Unitization Agreements for Oil and Gas Pools › Section 10 CSR 50-4.010 - Application for Authorization of a Pooling Unit for Primary Production

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: This amendment clarifies the process for
				  pooling mineral interests within a single spacing unit, either by voluntary or
				  involuntary pooling.
PURPOSE: This rule sets forth the procedure for
				  pooling mineral interests of separately-owned tracts, portions of tracts, or
				  interests within a single spacing unit for primary production, to allow for the
				  development and operations of the spacing unit.
(1) Before the
				commencement of drilling a well in a spacing unit, all owners, whether
				ownership is by deed or lease or farmout, shall enter into a contractual
				agreement whereby every owner pays his or her mutually agreed fair share of the
				drilling and operating costs and receives his or her fair share of the oil or
				gas or the profits produced therefrom. Contractual agreement is achieved by way
				of the pooling process pursuant to section
				259.110,
				RSMo. The pooling process may be either voluntary or involuntary, as defined as
				follows:
(A) A voluntary pooling occurs when
				all owners of mineral interests enter into a private contractual agreement
				willingly and of their own accord. Voluntary poolings are executed privately
				with no involvement by the council; and
(B) An involuntary pooling occurs when one
				(1) or more owners of mineral interests are not able to enter into a private
				contractual agreement willingly and of their own accord, and the council, upon
				application by any interested owner and after notice and hearing, issues a
				pooling order that serves as the binding contractual agreement.
Missouri Code of State Regulations › Title 10 - DEPARTMENT OF NATURAL RESOURCES › Division 50 - Oil and Gas Council › Chapter 4 - Authorization of Pooling Units and Unitization Agreements for Oil and Gas Pools › Section 10 CSR 50-4.020 - Application for Authorization of Unitization for Enhanced Recovery

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: This rule sets forth a procedure for small-
				  to large-scale cooperative development and operation projects that are designed
				  to maximize ultimate recovery of oil and gas from the entirety of a single pool
				  or particular portion thereof through the use of enhanced recovery projects
				  within production units. Similar to the pooling process for primary production,
				  unitization of production units for enhanced recovery involves contractual
				  agreements between different owners and/or operators of existing producing
				  wells, and a decision as to which one (1) of the operators will operate the
				  production unit as a whole.
(1) The council, upon the written request of
				an applicant and upon receipt of the information specified in section (2) of
				this rule and after notice and hearing, may approve the implementation of a
				production unit of a specified size and shape, and a well configuration of a
				certain nature of operation, for the purpose of a cooperative development and
				operation project designed to maximize the ultimate recovery of oil or gas or
				both from the entirety of a single pool or particular portion thereof. All
				operators and owners in the proposed production unit shall enter into
				contractual agreement such that one (1) party is designated the operator of the
				production unit as a whole, and every owner pays his or her mutually agreed
				fair share of the drilling and operating costs and receives his or her fair
				share of the oil, gas, or both produced from the unit, or the profits derived
				from such production. Contractual agreement is achieved by way of the
				unitization process, which is either voluntary or involuntary as defined as
				follows:
(A) A voluntary unitization occurs
				when all operators and owners in the proposed production unit area are able to
				enter into a private contractual agreement willingly and of their own accord;
				and
(B) An involuntary unitization
				occurs when one (1) or more operators or owners are not able to enter into a
				private contractual agreement willingly and of their own accord, and the
				council, upon application by any person or party representing the voluntarily
				agreed production unit proponents that collectively hold at least seventy-five
				percent (75%) of the right to drill into and to produce oil and gas from the
				pool and at least seventy-five percent (75%) of all mineral interest and after
				notice and hearing, may approve the implementation of the production unit and
				issue a unitization order that serves as a binding contractual agreement for
				all parties and that, if necessary, designates the operator of the production
				unit as a whole.
Missouri Code of State Regulations › Title 10 - DEPARTMENT OF NATURAL RESOURCES › Division 50 - Oil and Gas Council › Chapter 5 - Special Projects and Research Projects › Section 10 CSR 50-5.010 - Special Projects and Research Projects

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: This amendment deletes language that is
				  included in the proposed new rule 10 CSR 50-4.020 in order to make the rules
				  easier to read, incorporates requirements for special projects previously in
				  proposed rescission
				  10 CSR 50-2.110,
				  clarifies the role and authority of the state geologist to approve applications
				  for special projects and research projects, and changes the confidentiality
				  period to be consistent throughout 10 CSR 50.
PURPOSE: The oil and gas reserves of the state at any
				  one (1) time consist of that fraction of discovered oil and gas that can be
				  economically recovered using existing technology. Since optimum recovery is
				  dependent upon engineering and scientific achievements as well as economics,
				  any development of new processes represents an increase in oil and gas reserves
				  as well as an improvement in oil and gas conservation practices. By carefully
				  matching recovery processes to individual reservoirs, it should be possible to
				  greatly extend the potential that exists in unconventional oil and gas deposits
				  of Missouri. This rule permits the state geologist and the council to give
				  special consideration to development of potential resources such as
				  these.
(1) To encourage
				development of economic recovery of oil and gas reserves in the state, in
				particular the research and development leading to economic recovery of
				unconventional oil and gas reserves, research or special projects whose
				objective is to devise and develop methods may be approved by the state
				geologist as units complete within themselves. Unit approval may be obtained by
				submitting to the state geologist a project report specifying all pertinent
				details of the proposed research or development project. Blanket approval for
				an application for a permit to drill wells may be granted at the discretion of
				the state geologist, provided the location and numbers of the wells are
				anticipated with a reasonable degree of accuracy.
(2) No well drilled as an oil or gas well
				shall be drilled closer than approximately one hundred sixty-five feet (165')
				to a unit boundary.
(3) Reports of
				the pertinent details of overall project operation shall be submitted quarterly
				to the state geologist for his or her study and use. Confidentiality may be
				granted upon written request as required in
				10 CSR
				50-1.020.

				For the purpose of determining compliance with MCLs, a supplier of water must
				collect samples of the product water for analysis as follows:
(A) During the initial three (3)-year
				compliance period, all community and nontransient noncommunity water systems
				must collect an initial round of four (4) consecutive quarterly samples unless
				a waiver has been granted by the department. The department will designate the
				year in which each system samples within this compliance period;
(B) All public water systems shall sample at
				points in the distribution system representative of each water source or at
				each entry point to the distribution system. The sampling point will be after
				the application of treatment, if any. Each sample must be taken at the same
				sampling point unless conditions make another sampling point more
				representative of each source or treatment plant;
(C) If the system draws water from more than
				one (1) source and the sources are combined before distribution, the system
				must sample at an entry point to the distribution system during periods of
				normal operating conditions; and
(D) The department may require more frequent
				monitoring than specified in this section of the rule and may require
				confirmation samples for positive or negative results, at its
				discretion.

				contaminant levels for
Cryptosporidium.
These requirements are
				in addition to requirements for filtration and disinfection in
				10
				CSR 60-4.050 and
				10 CSR
				60-4.055.
(B) Applicability.
1. The requirements of this rule apply to all
				public water systems supplied by a surface water source and public water
				systems supplied by a ground water source under the direct influence of surface
				water.
2. Wholesale systems, as
				defined in
				10 CSR 60-2.015, must
				comply with the requirements of this rule based on the population of the
				largest system in the combined distribution system.
(C) Requirements. Systems subject to this
				rule must comply with the following requirements:
1. Systems must conduct an initial and a
				second round of source water monitoring for each plant that treats a surface
				water or ground water under the direct influence of surface water (GWUDISW)
				source. This monitoring may include sampling for
Cryptosporidium, E.
				coli,
and turbidity as described in sections (2)-(6) of this rule, to
				determine what level, if any, of additional
Cryptosporidium
treatment they must provide;
2.
				Systems that plan to make a significant change to their disinfection practice
				must develop disinfection profiles and calculate disinfection benchmarks, as
				described in sections (8) and (9) of this rule;
3. Filtered systems must determine their
Cryptosporidium
treatment bin classification as described in
				section (10) of this rule and provide additional treatment for
Cryptosporidium,
if required, as described in section (11) of
				this rule. Filtered systems must implement
Cryptosporidium
treatment according to the schedule in section (12) of this rule;
4. Systems required to provide additional
				treatment for
Cryptosporidium
must implement microbial toolbox
				options that are designed and operated as described in sections (13)-(18) of
				this rule; and
5. Systems must
				comply with the applicable record-keeping and reporting requirements described
				in
				10 CSR
				60-7.010 and

				CSR 60-9.010.
Missouri Code of State Regulations › Title 10 - DEPARTMENT OF NATURAL RESOURCES › Division 60 - Safe Drinking Water Commission › Chapter 4 - Contaminant Levels and Monitoring › Section 10 CSR 60-4.055 - Disinfection Requirements

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: The amendment updates regulation citations
				  due to concurrent rulemakings and removes language that has
				  sunset.
(1) The requirements
				of this rule apply to primary community and noncommunity public water systems
				that the department has required to disinfect and to secondary systems with a
				source of water from a primary water system that the department has required to
				disinfect, even if the water is obtained through another secondary system.
(A) Water systems using water obtained in
				whole or in part from a source determined by the department to be surface or
				ground water under the direct influence of surface water must install or
				construct facilities to provide conventional filtration treatment as a required
				treatment technique within eighteen (18) months of the determination.
(B) Any water system that the department
				determines to be a groundwater system under the direct influence of surface
				water may appeal the decision by notifying the department in writing. The
				appeal must be accompanied by a report prepared by an engineer that confirms
				that the water system's ground-water source is not directly influenced by
				surface water. The report must be supported by analytical data prepared by a
				laboratory that is acceptable to the department. Source sampling must be
				accomplished during the period the source is most susceptible to surface water
				influence. The department's approval of the report will result in the water
				system's source being redefined as groundwater not under the direct influence
				of surface water.
(C) If at any
				time in the department's opinion, the quality of a water source appears to have
				changed to be under the direct influence of surface water, the water system
				must submit, at the department's written request, an engineer-prepared report
				that describes the current condition of the water source. If a report is not
				submitted, the source will be reclassified as groundwater supply under the
				direct influence of surface water.
(D) The department reserves the authority to
				make the final determination of whether or not a source is defined as
				groundwater under the direct influence of surface water.
(E) Primary systems which use water obtained
				from groundwater not under the direct influence of surface water and which the
				department requires to disinfect and secondary public water systems do not have
				to meet the requirements of section (2) of this rule but may be required to
				provide disinfection detention as deemed necessary by the department. These
				systems also do not have to submit reports to the department as required by
				10 CSR
				60-7.010(4) but must maintain the
				information on file at the system treatment plant or
				office.
Missouri Code of State Regulations › Title 10 - DEPARTMENT OF NATURAL RESOURCES › Division 60 - Safe Drinking Water Commission › Chapter 4 - Contaminant Levels and Monitoring › Section 10 CSR 60-4.060 - Maximum Radionuclide Contaminant Levels and Monitoring Requirements

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: This amendment will remove language that has
				  sunset and incorporates a document by reference.
(1) Maximum Contaminant Levels (MCL).
(A) MCL for Combined Radium-226 and
				Radium-228. The maximum contaminant level for combined radium-226 and
				radium-228 is five picocuries per liter (5 pCi/l). The combined radium-226 and
				radium-228 value is determined by the addition of the results of the analysis
				for radium-226 and the analysis for radium-228.
(B) MCL for Gross Alpha Particle Activity
				(Excluding Radon and Uranium). The maximum contaminant level for gross alpha
				particle activity (including radium-226 but excluding radon and uranium) is
				fifteen picocuries per liter (15 pCi/l).
(C) MCL for Beta Particle and Photon
				Radioactivity.
1. The average annual
				concentration of beta particle and photon radioactivity from man-made
				radionuclides in drinking water must not produce an annual dose equivalent to
				the total body or any internal organ greater than four (4) millirem/year
				(mrem/year).
2. Except for the
				radionuclides listed in Table A, the concentration of man-made radionuclides
				causing four (4) mrem total body or organ dose equivalents must be calculated
				on the basis of two (2) liter per day drinking water intake using the one
				hundred sixty-eight (168) hour data list in "Maximum Permissible Body Burdens
				and Maximum Permissible Concentrations of Radionuclides in Air and in Water for
				Occupational Exposure," NBS (National Bureau of Standards) Handbook 69 as
				amended August 1963, U.S. Department of Commerce, which is incorporated by
				reference without any later amendments or modifications. If two (2) or more
				radionuclides are present, the sum of their annual dose equivalent to the total
				body or to any organ shall not exceed four (4) mrem/year.
