Sec. 503.1  Purpose and applicability.

    (a) Purpose. (1) This part establishes standards, which consist of
general requirements, pollutant limits, management practices, and
operational standards, for the final use or disposal of sewage sludge
generated during the treatment of domestic sewage in a treatment works.
Standards are included in this part for sewage sludge applied to the
land, placed on a surface disposal site, or fired in a sewage sludge
incinerator. Also included in this part are pathogen and alternative
vector attraction reduction requirements for sewage sludge applied to
the land or placed on a surface disposal site.
    (2) In addition, the standards in this part include the frequency of
monitoring and recordkeeping requirements when sewage sludge is applied
to the land, placed on a surface disposal site, or fired in a sewage
sludge incinerator. Also included in this part are reporting
requirements for Class I sludge management facilities, publicly owned
treatment works (POTWs) with a design flow rate equal to or greater than
one million gallons per day, and POTWs that serve 10,000 people or more.
    (b) Applicability. (1) This part applies to any person who prepares
sewage sludge, applies sewage sludge to the land, or fires sewage sludge
in a sewage sludge incinerator and to the owner/operator of a surface
disposal site.
    (2) This part applies to sewage sludge applied to the land, placed
on a surface disposal site, or fired in a sewage sludge incinerator.
    (3) This part applies to the exit gas from a sewage sludge
incinerator stack.
    (4) This part applies to land where sewage sludge is applied, to a
surface disposal site, and to a sewage sludge incinerator.

Sec. 503.2  Compliance period.

    (a) Compliance with the standards in this part shall be achieved as
expeditiously as practicable, but in no case later than February 19,
1994. When compliance with the standards requires construction of new
pollution control facilities, compliance with the standards shall be
achieved as expeditiously as practicable, but in no case later than
February 19, 1995.
    (b) The requirements for frequency of monitoring, recordkeeping, and
reporting in this part for total hydrocarbons in the exit gas from a
sewage sludge incinerator are effective February 19, 1994 or, if
compliance with the operational standard for total hydrocarbons in this
part requires the construction of new pollution control facilities,
February 19, 1995.

[[Page 687]]

    (c) All other requirements for frequency of monitoring,
recordkeeping, and reporting in this part are effective on July 20,
1993.

Sec. 503.3  Permits and direct enforceability.

    (a) Permits. The requirements in this part may be implemented
through a permit:
    (1) Issued to a ``treatment works treating domestic sewage'', as
defined in 40 CFR 122.2, in accordance with 40 CFR parts 122 and 124 by
EPA or by a State that has a State sludge management program approved by
EPA in accordance with 40 CFR part 123 or 40 CFR part 501 or
    (2) Issued under subtitle C of the Solid Waste Disposal Act; part C
of the Safe Drinking Water Act; the Marine Protection, Research, and

treating domestic sewage'' shall submit a permit application in
accordance with either 40 CFR 122.21 or an approved State program.
    (b) Direct enforceability. No person shall use or dispose of sewage
sludge through any practice for which requirements are established in
this part except in accordance with such requirements.

Sec. 503.4  Relationship to other regulations.

    Disposal of sewage sludge in a municipal solid waste landfill unit,
as defined in 40 CFR 258.2, that complies with the requirements in 40
CFR part 258 constitutes compliance with section 405(d) of the CWA. Any
person who prepares sewage sludge that is disposed in a municipal solid
waste landfill unit shall ensure that the sewage sludge meets the
requirements in 40 CFR part 258 concerning the quality of materials
disposed in a municipal solid waste landfill unit.

Sec. 503.5  Additional or more stringent requirements.

    (a) On a case-by-case basis, the permitting authority may impose
requirements for the use or disposal of sewage sludge in addition to or
more stringent than the requirements in this part when necessary to
protect public health and the environment from any adverse effect of a
pollutant in the sewage sludge.

thereof or interstate agency from imposing requirements for the use or
disposal of sewage sludge more stringent than the requirements in this
part or from imposing additional requirements for the use or disposal of
sewage sludge.
