Notice of Availability; Effluent Limitations Guidelines and
Pretreatment Standards for the Industrial Waste Combustors Subcategory
of the Waste Combustors Point Source Category
AGENCY: Environmental Protection Agency (EPA).
ACTION: Data availability related to proposed rule.
-----------------------------------------------------------------------
SUMMARY: On February 6, 1998 EPA proposed effluent limitations
guidelines and pretreatment standards for the Industrial Waste
Combustor (IWC) Subcategory of the Waste Combustors Point Source
Category to limit effluent discharges to waters of the United States
and the introduction of pollutants into publicly owned treatment works
(63 FR 6391). The comment period for the proposal closed on May 7,
1998.
Today, EPA is making available for public review and comment new
data on wastewater treatment system performance at IWC facilities. EPA
is considering using these data to derive final effluent limitations
and pretreatment standards for the IWC Subcategory.
EPA is soliciting comments only on the new information and data
being made available today.
DATES: Submit an original and three copies of your comments on or
before June 16, 1999.
ADDRESSES: Submit comments to Ms. Samantha Hopkins at the following
address: US EPA, Engineering and Analysis Division (4303), 401 M. St.
SW, Washington, DC 20460.
The data being made available today may be found in the EPA Water
Docket at EPA Headquarters at Waterside Mall, Room EB-57, 401 M. St.
SW, Washington, DC 20460. For access to the docket materials, call
(202) 260-3027 between 9:00 a.m. and 3:30 p.m. for an appointment. A
reasonable fee may be charged for copying.
FOR FURTHER INFORMATION CONTACT: Ms. Samantha Hopkins at (202) 260-7149
or at the following e-mail address: Hopkins.S[email protected].
SUPPLEMENTARY INFORMATION: On February 6, 1998 EPA proposed effluent
limitations guidelines and pretreatment standards (63 FR 6391) for the
Industrial Waste Combustor (IWC) Subcategory. The comment period closed
on May 7, 1998. These comments may be reviewed in the Water Docket at
EPA Headquarters (see address above).
In early 1999, subsequent to the close of the comment period, EPA
received wastewater treatment performance data from three IWC
facilities. The new data are now available for review in the Water
Docket in Section 16.4 of the record for this rulemaking. EPA is
evaluating the new data for its usefulness in establishing final
effluent limitations and standards. The Agency invites comment on the
new data, which are summarized below.
The three facilities provided data to EPA for their wastewater
treatment system performance. How EPA used such performance data when
it developed the proposed effluent limitations guidelines and standards
is described in Section 8 of the Development Document for Proposed
Effluent Limitations Guidelines and Standards for Industrial Waste
Combustors (EPA 821-B-97-011) and in Section 7 of the record for this
rulemaking.
Each of the three IWCs submitted influent and effluent wastewater
treatment system performance data and related information on the
operation of the treatment systems. Each facility submitted daily
measurements for chlorides, total dissolved solids, total suspended
solids, sulfate, pH, and 15 metals (aluminum, antimony, arsenic,
cadmium, chromium, copper, iron, lead, mercury, molybdenum, selenium,
silver, tin, titanium and zinc).
One facility provided 11 days of influent and effluent sampling
data from its wastewater treatment system. Its system consists of two
stages of chemical precipitation (with each stage followed by solid-
liquid separation) followed by sand filtration as the final treatment
step. This facility also provided six days of influent and effluent
sampling data with ``spiked'' influent levels of cadmium, chromium,
[[Page 26715]]
copper, lead, and zinc. The facility artificially increased the
influent concentrations of these five metals to simulate periodic peak
raw waste conditions.
The second facility provided 30 days of influent and effluent
sampling data from its wastewater treatment system. This system
consists of two stages of chemical precipitation (with each stage
followed by solid-liquid separation).
The third facility provided 30 days of influent and effluent
sampling data from its wastewater treatment system. Its system consists
of two stages of chemical precipitation (with each stage followed by
solid-liquid separation).
Dated: May 7, 1999.

Assistant Administrator for Water.
