R 325.1633a  Construction of wells; grouting.
  Rule 133a.  (1) Shale traps, cementing baskets, packers, or other devices shall must not be used to suspend grout above an open annular space. Excessive development, washing, shoveling of cuttings, or other similar activities shall must not be used to induce collapse of the borehole wall or to reduce the amount of open annular space surrounding a permanent casing.
  (2) Neat cement or bentonite grout shall must be placed through the permanent casing or a grout pipe from the bottom of the annular space upward to the ground surface in a continuous operation without interruption. The density of grout flowing from the annular space at the ground surface shall must be the density of the grout being pumped in.
  (3) A permanent casing shall must be installed in a borehole that has a diameter of not less than 2 inches larger than the nominal size of the permanent casing, except as provided in subrule (4) of this rule and R 325.1635.
  (4) When grout is placed through a grout pipe outside the permanent casing, the borehole diameter shall must be not less than 2-7/8 inches larger than the nominal casing size.
  (5) An annular space between a permanent casing and temporary casing shall must be grouted during temporary casing removal by pumping neat cement or bentonite grout, or by pouring bentonite chips, bentonite pellets, or granular bentonite, into the annular space. Granular bentonite shall must not be poured into an annular space that contains drilling fluid or water.
  (6) Neat cement shall must be allowed to set a minimum of 24 hours when standard type I, type IL, type Ia, type ILA, or  high-early type III, or type ILHE cement is used. If bentonite is added to neat cement, the grout shall must be allowed to set a minimum of 48 hours before drilling operations are resumed.
 
R 325.1640  Certification of water well components.
  Rule 140.  (1) Water supply system components that are in contact with groundwater shall must be free of materials that may adversely affect the aquifer or water pumped from the well and shall must not support microbiological growth.
  (2) After the effective date of this rule, January 1, 1994, a person an individual shall not use the following water well components unless they are in compliance with or surpass ANSI/NSF standard 14, 60, or 61, ASTM specification C 150, ASTM Specification C 595, or section 10 of API specification 10, as adopted by reference in R 325.1610: 
   (a) Drilling fluids, grouts, and casing sealing materials.
   (b) Additives to drilling fluids, grouts, and casing sealing materials.
   (c) Pipe joint compounds, thread cutting oils, gasket sealants, or coatings on steel pipe.
   (d) Solvent cements, primers, cleaners, or other compounds that are used with PVC pipe.
   (e) Bladders, diaphragms, coatings, or lining materials that are in contact with water in a pressure or storage tank.
   (f) Chemicals that are used for the development, maintenance, treatment, disinfection, or rehabilitation of a water well, except for sodium hypochlorite or calcium hypochlorite.
  (3) Acceptable water well components under ASTM specification C 595 are limited to the classification of product commonly known as Type IL-Portland-limestone cement.
