Responding to recommendations from owners and operators (O/Os) of electric power plants subject to the Mercury and Air Toxics Standards (MATS), the EPA is proposing final regulations to require the submission of compliance data through a single electric reporting system rather than through two systems as established by the original MATS (February 16, 2012, FR). The proposal would affect O/Os who use either performance stack testing or continuous monitoring to demonstrate compliance.

While the proposal would also increase the frequency of compliance reports from semiannual to quarterly, the EPA says implementation of a single reporting system will reduce the overall compliance burden and save the regulated sector about $4.2 million in annualized capital or operation and maintenance costs. Using a single system will also make data about emissions from power plants more transparent and accessible to the public, the Agency adds.
