Section 408.4058. Extension of internal inspection certificate to 24 or 36 months.

(1) An internal boiler inspection may be increased from an annual inspection to a 24-month inspection frequency by approval of the board of boiler rules.  An employee delegated by the utility or industrial facility shall apply for the extension and submit a copy of the document that controls its program for approval by the board of boiler rules. The information shall be addressed by plant orders, procedures, or policies. The following information may be contained in 1 document or several documents if 1 document contains references to all other documents addressing the required information:

(i)     Operator training.

(ii)     Boiler maintenance.

(iii)     Water chemistry.

(iv)     Operating parameters.

(v)     Chemical cleaning schedule.

(vi)     Protective devices.

(vii)     Boiler external inspection.

(viii)         Testing  of  pressure   relief  devices  pursuant  to  the  NBIC.     Repairs  shall  be conducted by the valve manufacturer or a “VR” stamp holder.

(2)    The plant owner shall establish a review committee. The inspector shall be a member of the committee. The purpose of the committee is to determine the acceptability of a boiler to operate safely for a 24-month period. The committee shall have access to and review all information pertaining to the past operation, maintenance,

and repair of the boiler. The review committee meeting shall be conducted within 30 days after the internal inspection. The committee may decrease the period of time the boiler may operate, but shall not extend the period beyond 24 months. The signed summary report of the review committee meeting shall be submitted to the boiler division of the department. The grace period provided under R 408.4057 does not apply to this rule. The inspector shall indicate the next inspection due date on his or her inspection report to the boiler division of the department.

(3)     An internal boiler inspection may be increased from a 24-month inspection to a 36- month inspection frequency by approval of the board of boiler rules. An employee designated by the utility or industrial facility shall request in writing the extension and shall submit a copy of the document that controls its program with supporting documentation that demonstrates compliance with all of the following for approval by the board of boiler rules:

(iii)       The owner has installed instrumentation available and functioning for continuous monitoring of water chemistry parameters as identified by the boiler manufacturer and routine calibration is performed. This instrumentation shall be maintained on a list for each boiler that applies to this paragraph.

(iv)      The owner has a program for routine monitoring of the water chemistry condition, which includes physical samples being analyzed by the owner’s staff. The owner shall maintain a list of the physical samples for each boiler that applies to this paragraph.

(v)       The owner has alarm response procedures that provide direction to operators for actions to correct variations to chemistry parameters that include removing the boiler from service.

(d)        The establishment of a review committee whose purpose is to determine the acceptability of a boiler to operate safely for a 36-month period. The review committee shall be made of, at a minimum, the following members:

(i)     A representative from the owner’s boiler operating and maintenance organization.

(ii)      A representative from the owner’s organization designated to provide oversight to boiler maintenance and monitoring of boiler condition.

The boiler internal inspection may occur at any time during the outage period. The next operating period shall be calculated based on the date of the certificate inspection conducted during this period.

(4)     An external inspection of the boiler shall be conducted while under pressure, within 12 months of the certificate inspection, and every 12 months thereafter until the next boiler internal inspection.
