Section 680IAC2-3-9. Frequency of inspections

   (a) All boilers subject to inspection, other than steam generating equipment which is an integral part of a continuous processing unit such as used in chemical manufacture or petroleum refining, shall be inspected at the interval specified as follows:

(1) Power boilers and miniature boilers shall be given certificate inspections at twelve (12) month intervals internally where construction permits, and externally while not under pressure; and shall also be inspected externally while under pressure, if possible, approximately six (6) months from the date of the certificate inspection.

(2) The certificate inspection period for a specific boiler may be extended to a maximum of six (6) months beyond the certificate expiration date with the approval of the inspection agency having jurisdiction and the office of the state building commissioner in order to allow for unexpected plant operational difficulties. A written request for an extension beyond the certificate expiration date in the form of a letter stating the operational difficulties shall be submitted by the owner to the office. An extension shall be permitted at the discretion of the office.

(3) A power boiler with rated steaming capacity of three hundred thousand (300,000) pounds per hour or more shall be permitted to be inspected internally at a greater interval provided the conditions of subsection (3)(A), (B), and (C) [sic., this subdivision] are met; however, external inspections shall continue to be conducted at approximately six (6) month intervals, while the boiler is under pressure.

(A) A written request for an extension beyond the certificate expiration date shall be submitted by the owner to the board.

(B) A report of inspection indicating that a certificate inspection has been completed is submitted to the board by the inspection agency.

(C) A document, such as a letter from the inspection agency, signed by a responsible person of that agency shall accompany the report of inspection attesting to:

(i) The use of the boiler.

(ii) The nameplate data, state number, and any national board numbers.

(iii) The name and pertinent qualifications of the person(s) in charge of water treatment.

(iv) Adequacy of the laboratory facilities and a review of written procedures and data for water chemistry analysis and treatment of boiler water. The written procedure for sampling water is to include the method, frequency, parameters, and limits.

(v) A review of the record of boiler outages occurring since the last internal inspection.

(vi) The acceptability of the documentation reviewed and acceptance of the extended interval.

If the request for an extended certificate in subsection (a)(3) [sic., this subdivision] is granted, the certificate shall not exceed twenty-four (24) months. At the end of the interval, the boiler for which the request was made shall revert to the twelve (12) month inspection requirement of subsection (a)(1) [sic., subdivision (1)] for power boilers unless a request is submitted to, and approved by, the office.

(4) Low pressure steam heating boilers, hot water heating boilers and hot water supply boilers, and service water heaters shall be given a certificate inspection biennially externally and, where construction will permit, internally. The internal inspection of low pressure hot water heating boilers, hot water supply boilers, and service water heaters shall be at the direction of the inspector.

  (b) All unfired pressure vessels subject to inspection under IC 22-15-6, and any steam generating equipment subject to such inspection that is an integral part of any continuous processing unit such as used in chemical manufacture or petroleum refining, shall be given a certificate inspection at intervals not exceeding three (3) years. Where systematic corrosion data are available, the maximum period between certificate inspections shall be five (5) years, or such shorter period as the inspection agency having jurisdiction deems proper. The maximum period between certificate inspections shall be indicated on the inspector's report.

  (c) The periods specified in subsections (a) and (b) shall be subject to a two (2) month grace period.

  (d) Owner or user inspection agencies shall observe the same frequencies of inspection as outlined in subsections (a) (b) and shall be permitted a corresponding two (2) month grace period on intervals between inspections; however, inspection certificates are not required in such cases.
