The Clean Water Act (CWA) directs EPA
to develop regulations, called effluent guidelines, to limit the
amount of pollutants that are discharged to surface waters or to
sewage treatment plants. The effluent guidelines for the steam
electric power generating point source category apply to steam
electric generating units at establishments that are primarily
engaged in the generation of electricity for distribution and sale,
resulting primarily from a process using nuclear or fossil-type
fuels, such as coal, oil and natural gas. EPA first identified the
industry during its 2005 annual review of discharges from
categories with existing effluent guidelines regulations, when
publicly available data indicated that this industry ranked high in
discharges of toxic and nonconventional pollutants. Because of
these findings, EPA initiated a more detailed study of the industry
and collected data through site visits, wastewater sampling, a
limited data request, and secondary sources of data. EPA determined
that steam electric power plants are responsible for a significant
amount of the toxic pollutant loadings discharged to surface waters
by point sources. Further information regarding these conclusions
can be found in EPA's study, Steam Electric Power Generating Point
Source Category: Final Detailed Study Report (EPA 821-R-09-008).
This ICR will support the review and revision of the Steam Electric
ELGs. EPA is requesting the Office of Management and Budget (OMB)
to review and approve the ICR for Steam Electric Power Generating
Effluent Guidelines. The ICR will aid in the collection of
information from a wide range of steam electric power generating
industry operations to characterize waste streams, understand the
processes that generate the wastes, gather environmental data, and
assess the availability and affordability of treatment
technologies. These data will be used to perform detailed technical
and economic analyses that will support EPA's rulemaking. EPA has
identified approximately 1,200 fossil- and nuclear-fueled steam
electric power plants that are potentially within scope of the data
collection objectives of the questionnaire. To reduce burden on the
industry, EPA intends to distribute the questionnaire to a
statistically-sampled subset of these facilities. After addressing
comments provided during the first FRN publication comment period,
which ended on December 28, 2009, EPA estimates that approximately
734 fossil- or nuclear-fueled steam electric plants will be
required to complete Parts A and I of the questionnaire. This is a
decrease in the number of respondents, from 760 to 734. The
questionnaire consists of multiple sections which have been
tailored to address specific processes, specific data needs, or
types of power plants. Parts A and I of the questionnaire will be
sent to all questionnaire recipients (734 plants); the remaining
sections will be sent to discrete subpopulations of questionnaire
recipients. Overall, EPA estimates a reduction of 11,640 hours in
respondent burden as a result of the revisions of the
questionnaire. The questionnaire will collect general plant
information and selected technical information about the plant
processes and the electric generating units. The information that
will be collected includes economic data and technical information
about flue gas desulfurization (FGD) wastewater, ash handling,
process equipment cleaning operations, wastewater treatment,
surface impoundment and landfill operations, and nuclear
operations. The questionnaire will also require certain power
plants to collect and analyze samples of leachate from surface
impoundments and landfills containing coal combustion residues.
More details about information requested in each section of the
questionnaire are provided in the ICR supporting
statement.
