New Source Performance Standards and Emissions Guidelines: Sewage
Sludge Incinerators
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of Additional Information (NAI).
-----------------------------------------------------------------------
SUMMARY: This action announces the EPA's intention to issue regulations

Incinerators (SSI) that combust sludge from Publicly Owned Treatment
Works and to remove Sewage Sludge Incinerators from the list of Major
Source Categories previously scheduled for rule development under
Section 112 of the Clean Air Act.

SUPPLEMENTARY INFORMATION: The information in this preamble is
organized as follows:
1. Background
The Clean Air Act as amended November 1990, requires under the
revisions to Section 112, that the Agency list and promulgate National
Emissions Standards for Hazardous Air Pollutants (NESHAP) in order to
control, reduce, or otherwise limit the emissions of HAP for categories
of major and area sources. Pursuant to the various specific listing
requirements in Section 112(c), the Agency published on July 16, 1992
(57 FR 31576) an initial list of 174 categories of major and area
sources that would be henceforth subject to emissions standards. Sewage
Sludge Incineration (SSI) was one of the 174 categories listed for
development of a NESHAP.
Following this initial listing, and pursuant to requirements in
Section 122(e), on December 3, 1993 (58 FR 63941), the Agency published
a schedule for the promulgation of emission standards for each of the
174 listed source categories. The SSI were listed for promulgation of a
NESHAP no later than November 15, 2000. The reader is directed to those
two notices for information relating to development of the initial list
and schedule.
The Agency published a Notice of Listing of Categories and
Regulatory Schedule for Air Emissions From Other Solid Waste
Incineration (OSWI) on November 2, 1993 (58 F.R. 58498). The New Source
Performance Standards (NSPS) and Emissions Guidelines (EG) for OSWI's
are to be developed under section 129 of the Clean Air Act. That notice
listed seven categories of OSWIs. The notice established a promulgation
date for rulemaking for the seven categories of OSWI's of no later than
November 15, 2000. Incineration of sludge from publicly owned waste
water treatment works (POTW's) was not listed.
The Agency published an Advanced Notice of Proposed Rulemaking
(ANPRM) for NSPS and EG applicable to Industrial and Commercial Waste
Incinerators (ICWI) and Other Solid Waste Incinerators (OSWI) on
December 28, 1994 (59 FR 66850). That notice announced the EPA's intent
to develop NSPS and EG under Section 129 of the Act for the seven OSWI
categories and ICWIs. Not included among the listed categories were
incinerators used to combust sewage sludge produced at POTWs.
Today's Notice of Additional Information is announcing EPA's
oversight in not listing SSI's in the November 2, 1993 listing of OSWI.
The Agency, on closer reading of Section 129 of the Act, has now
determined that SSI should properly be regulated under Section 129
rather that Section 112. Section 129 requires the EPA to establish NSPS
for new and EG for existing facilities, for each category of solid
waste incineration units. Section 129 defines a solid waste
incineration unit as ``a distinct operating unit of any facility which
combusts any solid waste material from commercial or industrial
establishments or the general public (including single and multiple
residences, hotels, and motels).'' Sludge generated by POTWs is a solid
waste from the general public, commercial and industrial
establishments.
Regulation of SSI under Section 129 provides for regulation of four
criteria pollutants that are not listed as Hazardous Air Pollutants in
Section 112. Also Section 129 provides for regulation of both new and
existing units and does not have the major source quantity cutoff of
Section 112(a)(1). Development of guidelines for operator training and
certification of SSI operators is also a requirement of Section 129.
These provisions will give the EPA more flexibility in setting rules
for different sizes of SSI and will assure the public that the SSI are
being operated in a manner that will protect the public health. The
promulgation date for an NSPS and EG applicable to SSI remains no later
than November 15, 2000.
The Agency also notes that this action announces the EPA's intent
to delist SSI from the Section 112(c) source category list and the
112(e) schedule and to add SSI to the list of categories of Other Solid
Waste Incinerators. At the time of proposal of the NSPS and EG under
Section 129, the SSI will be delisted from the Section 112(c) list and
the 112(e) schedule and added to the list of categories and regulatory
schedule for Other Solid Waste Incinerators.
Dated: January 8, 1997.

Assistant Administrator for Air and Radiation.
