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).

Assistant Administrator for Water.
