Section 1222. Special equalization rates; state assessments

1.  (a) If the
  state board finds that there has been a  material  change  in  level  of
  assessment,  it shall determine a special equalization rate for purposes
  of the assessment of special franchises and the approval of  assessments
  of  taxable  state  lands.  The state board shall adjust the assessments
  affected  by  this  special  equalization  rate  and  shall  notify  the
  appropriate  assessor, county director of real property tax services and
  special franchise owner.
    (b) Upon receipt of the notice referred to in paragraph  (a)  of  this
  subdivision,  the  assessor  shall  make  the appropriate changes on the
  assessment roll. If the notice is received after the filing of the final
  assessment roll but at least ten days prior to the last day set  by  law
  for  a  levy of taxes on that roll, the assessor shall notify the person
  or persons having custody and control of the roll for that levy  of  the
  changes  to  be  made  thereto  and  shall  provide that person or those
  persons with a copy of the notice received  by  the  assessor  from  the
  state  board.  The person or persons shall enter the changes on the roll
  and affix the notice from the state board.
    (c) If the assessor or other local official  is  unable  to  make  the
  appropriate  changes  within  the time provided in paragraph (b) of this
  subdivision, and those changes would have increased the taxable assessed
  value, the assessor shall determine the  amount  of  assessed  valuation
  which  was  not  subject to such tax levy and shall enter that amount on
  the assessment roll of the succeeding year in the  manner  provided  for
  the  entry  of  omitted  real property by title three of article five of
  this chapter. If those changes would have decreased the assessed  value,
  correction shall be made in the manner provided for the correction of an
  unlawful entry by title three of article five of this chapter.
    2.  If  the state board finds that there has been a change in level of
  assessment which is not a material change in level of assessment, and if
  a request for a special equalization rate is filed with the state  board
  by  either  the  assessing  unit or a special franchise owner, the state
  board  shall  determine  a  special  equalization  rate  for  assessment
  purposes  if it can do so not later than ten days prior to the last date
  set by law for the levy of taxes. The state board shall thereupon adjust
  the assessments affected by such special  equalization  rate  and  shall
  notify  the  appropriate  assessor, county director of real property tax
  services and special franchise owners. Upon receipt of this notice,  the
  assessor  or  other  local  official  having  custody and control of the
  assessment roll shall make the appropriate  changes  on  the  assessment
  roll, as provided in paragraph (b) of subdivision one of this section.
