Steam Electric Power Generating Effluent Guidelines – 2019 Proposed Revisions
is proposing revisions to the September 30, 2015 Final Rule for flue gas desulfurization (FGD) wastewater and for bottom ash (BA) transport water applicable to the Steam Electric Power Generating category.
The EPA estimates that its proposed rule would result in compliance cost savings of more than $175 million pre-tax annually while reducing the amount of pollutants discharged to our nation’s waters by approximately 100 million pounds per year over the existing Obama-era regulation as a result of:
- less costly FGD wastewater technologies that could be used to comply with the proposed relaxation of the 2015 rule’s selenium limit
- less costly BA transport water technologies that could be used to comply with the proposed relaxation of the 2015 rule’s requirement to recycle 100 percent of the system water
- a two-year extension of compliance time frames for FGD wastewater, and
- additional proposed subcategories for both FGD wastewater and BA transport water.
The additional pollutant reductions are attributable to a voluntary incentives program that provides the certainty of more time (until December 31, 2028) for plants to implement new requirements, if they adopt additional process changes and controls that achieve more stringent limitations on mercury, arsenic, selenium, nitrate/nitrite, bromide, and total dissolved solids in FGD wastewater.
The proposed rule has been signed by the EPA Administrator and is being prepared for publication.
