(ii) When drilling through the storage reservoir, the drilling fluid shall have a
maximum fluid loss of 15 cubic centimeters or less as specified by the API standard
procedure for testing drilling fluids, API RP 13B-1, entitled “Recommended Practice for
Field Testing Water-Based Drilling Fluids,” March, 2009, fourth edition, which is
adopted by reference in these rules. Copies are available for inspection at the Lansing
office of the office of oil, gas, and minerals of the department of environmental quality.
Copies may be obtained from the Michigan Department of Environmental Quality, Office
of Oil, Gas, and Minerals, P.O. Box 30256, Lansing, Michigan 48909, at a cost as of the
time of adoption of these rules of $165.00 each, and from the American Petroleum
Institute, 1220 L Street NW, Washington, DC 20005, at a cost as of the time of adoption
of these rules of $165.00 each.
(f) Hole size shall be large enough to allow the running of a separate intermediate
casing, which shall be set through each gas storage reservoir. The casing shall be new and
conform to the API specification and performance properties for casing, tubing, and drill
pipe, API BULL 5C3, entitled “Bulletin on Formulas and Calculations for Casing,
Tubing, Drill Pipe, and Line Pipe Properties, October 1, 1994,” sixth edition, which is
adopted by reference in these rules. Copies are available for inspection at the Lansing
office of the office of oil, gas, and minerals of the department of environmental quality.

time of adoption of these rules of $206.00 each, and from the American Petroleum
Institute, 1220 L Street NW, Washington, DC 20005, at a cost as of the time of adoption
of these rules of $206.00 each. The gas storage operator shall be allowed to review the
intermediate casing design and cementing program before implementation. Intermediate
casing shall be set in competent stratum approximately 100 feet below the base of the gas
storage reservoir or set as required by the supervisor or authorized representative of the
supervisor. Intermediate casing shall be designed for the maximum gas storage reservoir
operating pressure using a minimum collapse design factor of 1.125, a minimum burst
design factor of 1.25, and a minimum tension design safety factor of 1.6. The minimum
hole size for a given size casing shall be pursuant to R 324.410(4). The hole shall be
properly conditioned before running casing by circulating the drilling fluid at a rate equal
to the drilling circulating rate and by utilizing a circulating time equivalent of not less
than twice the hole displacement. Casing shall be equipped with a sufficient number of
centralizers and scratchers to ensure good cement distribution and shall include
centralizers above and below the gas storage reservoir. All centralizers shall conform to
the API for casing centralizers, API specification 10D, entitled “Specification for Bow-
Spring Casing Centralizers,” March 6, 2002, sixth edition, which is adopted by reference
in these rules. Copies are available for inspection at the Lansing office of the office of oil,
gas, and minerals of the department of environmental quality. Copies may be obtained
from the Michigan Department of Environmental Quality, Office of Oil, Gas, and
Minerals, P.O. Box 30256, Lansing, Michigan 48909, at a cost as of the time of adoption
of these rules of $89.00 each, and from the American Petroleum Institute, 1220 L Street
NW, Washington, DC 20005, at a cost as of the time of adoption of these rules of $89.00
each. Casing shall include float equipment that will prevent movement after the
cementing operation is completed. If conditions allow, casing shall be rotated or
reciprocated slowly during cementing. The mill varnish shall be removed from the casing
