          sections 183.375, subdivision 2; 183.411, subdivision 
          2, and by adding a subdivision; 183.42; 183.545,

    Section 1.  Minnesota Statutes 1986, section 183.375, 
subdivision 2, is amended to read:  
    Subd. 2.  [CHIEF OF DIVISION.] Subject to the provisions of 
chapter 43A, the commissioner shall appoint a chief and may 
appoint a deputy chief of the division of boiler 
inspection.  They The appointee shall be a qualified steam 
engineers engineer with at least ten years of operation 
experience as such, five years of boiler inspection experience, 
and shall be licensed as a chief Grade A engineers engineer in 
this state and shall possess a current commission issued by the 
national board of boiler and pressure vessel inspectors.  
Inspectors employed in the division of boiler inspection may 
utilize up to five years of equivalent experience as inspectors, 
in satisfying the requirement of ten years of experience as 
steam engineers for the chief and deputy chief positions.  
    Sec. 2.  Minnesota Statutes 1986, section 183.411, 
subdivision 2, is amended to read:  
    Subd. 2.  [INSPECTION.] When used only for display and 
demonstration purposes, steam farm traction engines, portable 
and stationary show engines and portable and stationary show 
boilers shall be inspected every two years according to law. 
    (a) Boilers or show engines of lap seam construction not 
certified in Minnesota or previously certified in Minnesota but 
that have been repaired or altered after certification, may be 
certified in Minnesota if:  
    (1) all alterations have been done in accordance with 
American National Standard ANSI/NB23 R-404 or R-505; or 
    (2) form R-1, report of alteration, has been prepared by a 
registered professional engineer with verification by the 
authorized inspection agency responsible for the in-service 
inspection of the object in accordance with American National 
Standard ANSI/NB23 R-502; or 
    (3) the engine has received a certificate allowing 
operation, or repairs have been authorized under American 
National Standard ANSI/NB23 R-404.1, R-404.2, or R-404.3 in 
Minnesota or another jurisdiction that accepts the provisions of 
American National Standard ANSI/NB23 and an inspection has been 
completed by an inspector certified in Minnesota according to 
the standards set in paragraph (b). 
    (b) A hobby boiler or show engine, not certified in 
Minnesota or any other jurisdiction must successfully complete, 
at the owner's expense, inspection by:  
    (1) full radiographic examination of the long or 
longitudinal seam; and 
    (2) ultrasonic examination for metal thickness (for 
purposes of calculating the maximum allowable working pressure 
the thinnest reading shall be used - see also American National 
Standard ANSI/NB23 I-303.8); and 
    (3) magnetic particle or radiographic examination of areas 
where dye penetrant testing shows possible cracks; and 
    (4) hydrostatic testing at one and one-half maximum 
allowable working pressure.  
    (c) Further each such object shall successfully complete an 
inspection of:  
    (1) the fusible plug; 
    (2) the safety valve, which must be of American society of 
mechanical engineer's approved design and set at the maximum 
allowable working pressure and sealed in an appropriate manner 
not allowing tampering with the valve setting without destroying 
the seal; and 
    (3) the boiler power piping.  
    Any longitudinal cracks found in riveted longitudinal seams 
requires that the vessel be sealed and not approved for use in 
Minnesota.  If the boiler or show engine is jacketed, the jacket 
must be removed prior to inspection. 
    Sec. 3.  Minnesota Statutes 1986, section 183.411, is 
amended by adding a subdivision to read: 
    Subd. 2a.  [INSPECTION FEES.] The commissioner may set fees

pursuant to section 16A.128. 
    Sec. 4.  Minnesota Statutes 1986, section 183.42, is 
amended to read:  
    Every owner, lessee, or other person having charge of 
boilers, pressure vessels or any boat subject to inspection 
under this chapter shall cause the same to be inspected by the 
division of boiler inspection.  Boilers and boats subject to 
inspection under this chapter shall be inspected at least 
annually and pressure vessels inspected at least every two 
years.  A person who fails to have the inspection required by 
this section shall pay to the commissioner a penalty in the 
amount of the cost of inspection up to a maximum of $1,000. 
    Sec. 5.  Minnesota Statutes 1986, section 183.545,

    (a) chief engineer's license;  
    (b) first class engineer's license;  
    (c) second class engineer's license; and 
    (d) special engineer's license;  
    (e) traction engineer's license; and 
    (f) pilot's license. 
    If an applicant, after an examination, is entitled to 
receive a license, it shall be issued without the payment of any 
additional charge.  Any license so issued expires one year after 
the date of its issuance.  An engineer's license may be renewed 
upon application therefor and the payment of an annual renewal
