Section 7 CCR 1101-5-2-1 - Inspection Schedule

(a) All new and reinstalled boilers shall receive an initial certificate inspection by a State Inspector. Upon successful installation, completion of inspection and payment of fees, the Director shall issue a certificate of boiler and pressure vessel inspection.

(b) Pursuant to 9-4-108 CRS, all owners or responsible parties of regulated boilers shall allow access for inspection of a boiler as requested by a State or Special Inspector.

(c) Except as permitted in (c)(1) of this Section, power boilers and high-temperature water boilers shall receive a certificate inspection annually, which shall be an internal inspection where construction permits; otherwise, it shall be as complete an inspection as possible. Such boilers shall also be inspected externally on an annual frequency while under normal operating conditions.

(1) Alternative internal inspection requirements

(A) The inspection frequency for fully-attended power boilers and high-temperature boilers may be extended to 36 months if the following requirements are met and approved by the Director:

(1) Continuous boiler water treatment under the direct supervision of persons trained and experienced in water treatment for the purpose of controlling and limiting corrosion and deposits.

(2) Record-keeping available for review, showing:

(i) The date and time the boiler is out of service and the reason therefore.

(ii) Daily analysis of water samples that adequately show the conditions of the water and elements or characteristics that are capable of producing corrosion or other deterioration to the boiler or its parts.

(3) Controls, safety devices, instrumentation and other equipment necessary for safe operation are up-to-date, in service, calibrated and meet the requirements of an appropriate safety code for that size boiler, such as NFPA 85, ASME CSD-1, National Board Inspection Code ANSI/NB-23 or jurisdictional requirements and are not compromised.

(B) Inspection intervals greater than 36 months may be granted at the discretion of the Director.

(d) ASME Section IV boilers covered by these rules and regulations shall receive a certificate inspection every two years, with an internal inspection at the discretion of a State or Special Inspector, where construction permits.

(1) Steam or vapor boilers shall have an external inspection or an internal inspection every two years.

(2) Hot water heating and hot water supply boilers shall have an external inspection every two years and, where construction permits, an internal inspection at the discretion of the State or Special Inspector.

(3) Water heaters, including hot water storage tanks, shall have an external inspection every two years which shall include an inspection of the function of all controls and devices.

(4) Indirect-fired jacketed steam kettles shall be inspected when the boiler providing steam to the kettle is inspected, although no certificate of inspection shall be issued by the Director.

(5) Hot water storage tanks shall be inspected when the hot water heating boiler or hot water supply boiler is inspected, although no separate certificate of inspection will issued by the Director.

(e) Based upon documentation of such actual service conditions by the owner or user of the operating equipment, the Director may, at his/her discretion, permit variations in the inspection frequency requirements as provided in the Act.

(f) Historical boilers, defined as steam boilers of riveted construction that are preserved, restored or maintained for hobby or demonstration use, shall be subjected to an initial certificate inspection followed by a certificate inspection every three years thereafter if stored inside a shelter and annually if stored outdoors. The initial inspection shall include ultrasonic thickness testing of all pressure boundaries provided by an authorized non-destructive examination testing entity as defined in NBIC. All thinned areas shall be monitored and recorded on the inspection report both to the owner and Director's electronic copy in the comments section.

(g) When a boiler, water heater, or direct-fired jacketed steam kettle that is required to have an operating certificate has a noted deficiency or a requirement for repair from an inspector authorized to inspect boilers or pressure vessels in the State of Colorado, the Inspector shall re-inspect the pressure-retaining item within 90 days from the date the requirement or deficiency was first noted. The Inspector may omit this re-inspection at his/her discretion.
