(2) The Administrator, in monitoring visibility within each such area, shall determine both background visibility conditions and reasonably attributable visibility impairment caused by a source or small group of sources for that area. The extent and the form of monitoring shall be sufficient for use in determining the potential effects of a new stationary source on visibility in the area, the stationary source or sources that are causing any visibility impairment, and progress toward remedying that impairment.

The Administrator shall make these plans available to the public.
(5) The Administrator shall establish a central repository of monitoring data that includes any data on background visibility conditions and reasonably attributable impairment that the Administrator collects under this section and that the Federal land manager may collect or may have collected independently. These data shall be available to any person, subject to reasonable charges for copying.
(d) Monitoring Plan Revision. (1) The Administrator shall review the monitoring plan annually for each visibility protection area, revise it as necessary, and include an assessment of changes to visibility conditions since the last review. The Administrator shall make all plan revisions available to the public.
