(a) Coverage. The Department may issue a general permit in accordance with the following:
(1) Area. The general permit shall be written
to cover one or more categories or subcategories of discharges or facilities
described in the permit under paragraph (a)(2)(ii) of this section, except
those covered by individual permits, within a geographic area. The area should
correspond to existing geographic or political boundaries, such as:
(i) Designated planning areas under sections
208 and 303 of CWA;
(ii) Sewer
districts or sewer authorities;
(iii) City, county, or State political
boundaries;
(iv) State highway
systems;
(v) Standard metropolitan
statistical areas as defined by the Office of Management and Budget;
(vi) Urbanized areas as designated by the
Bureau of the Census according to criteria in 30 FR 15202 (May 1, 1974);
or
(vii) Any other appropriate
division or combination of boundaries.
(2) Sources. The general permit may be
written to regulate one or more categories or subcategories of discharges or
facilities, within the area described in paragraph (a)(1) of this section,
where the sources within a covered subcategory of discharges are either:
(i) Storm water point sources; or
(ii) One or more categories or subcategories
of point sources other than storm water point sources, or a category of
''treatment works treating domestic sewage,'' if the sources or ''treatment
works treating domestic sewage'' within each category or subcategory all:
(A) Involve the same or substantially similar
types of operations;
(B) Discharge
the same types of wastes;
(C)
Require the same effluent limitations or operating conditions;
(D) Require the same or similar monitoring;
and
(E) In the opinion of the
Department, are more appropriately controlled under a general permit than under
individual permits.
(3) Where sources within a specific category
or subcategory of dischargers are subject to water quality-based limits imposed
pursuant to Chapter 523(5), the sources in that specific category or
subcategory shall be subject to the same water quality-based effluent
limitations.
(4) The general permit
must clearly identify the applicable conditions for each category or
subcategory of dischargers or treatment works treating domestic sewage covered
by the permit.
(5) The general
permit may exclude specified sources or areas from coverage.
(b) Administration
(1) In general. General permits may be
issued, modified, revoked and reissued, or terminated in accordance with
applicable requirements of Chapter 522. The Department may make proposals for
initial or modified general permits where it finds a need compatible with the
intent of this rule. Other persons may petition the Department to adopt or
modify a general permit.
(2)
Authorization to discharge
(i) Except as
provided in paragraphs (b)(2)(v) and (b)(2)(vi) of this section, dischargers
(or treatment works treating domestic sewage) seeking coverage under a general
permit shall submit to the Department a written notice of intent to be covered
by the general permit. A discharger (or treatment works treating domestic
sewage) who fails to submit a notice of intent in accordance with the terms of
the permit is not authorized to discharge, under the terms of the general
permit unless the general permit, in accordance with paragraph (b)(2)(v) of
this section, contains a provision that a notice of intent is not required or
the Department notifies a discharger (or treatment works treating domestic
sewage) that it is covered by a general permit in accordance with paragraph
(b)(2)(vi) of this section. A complete and timely notice of intent (NOI), to be
covered in accordance with general permit requirements, fulfills the
requirements for permit applications for purposes Chapter 521.
(ii) The contents of the notice of intent
shall be specified in the general permit and shall require the submission of
information necessary for adequate program implementation, including at a
minimum, the legal name and address of the owner or operator, the facility name
and address, type of facility or discharges, and the receiving stream(s).
General permits for storm water discharges associated with industrial activity
from inactive mining, inactive oil and gas operations, or inactive landfills
occurring on Federal lands where an operator cannot be identified may contain
alternative notice of intent requirements. All notices of intent shall be
signed in accordance with Chapter 521. Notices of intent for coverage under a
general permit for concentrated animal feeding operations must include the
information specified in Chapter 521(4)(i)(1), including a topographic
map.
(iii) General permits shall
specify the deadlines for submitting notices of intent to be covered and the
date(s) when a discharger is authorized to discharge under the
permit;
(iv) General permits shall
specify whether a discharger (or treatment works treating domestic sewage) that
has submitted a completed and timely notice of intent to be covered in
accordance with the general permit and that is eligible for coverage under the
permit, is authorized to discharge, in accordance with the permit either upon
receipt of the notice of intent by the Department, after a waiting period
specified in the general permit, on a date specified in the general permit, or
upon receipt of notification of inclusion by the Department. Coverage may be
terminated or revoked in accordance with paragraph (b)(3) of this
section.
(v) Discharges other than
discharges from publicly owned treatment works, combined sewer overflows,
municipal separate storm sewer systems, primary industrial facilities, and
storm water discharges associated with industrial activity, may, at the
discretion of the Department, be authorized to discharge under a general permit
without submitting a notice of intent where the Department finds that a notice
of intent requirement would be inappropriate. In such cases, the Department may
require some other form of notification. In making such a finding, the
Department shall consider: the type of discharge; the expected nature of the
discharge; the potential for toxic and conventional pollutants in the
discharges; the expected volume of the discharges; other means of identifying
discharges covered by the permit; and the estimated number of discharges to be
covered by the permit. The Department shall provide in the public notice of the
general permit the reasons for not requiring a notice of intent.
(vi) The Department may notify a discharger
(or treatment works treating domestic sewage) that it is covered by a general
permit, even if the discharger (or treatment works treating domestic sewage)
has not submitted a notice of intent to be covered. A discharger (or treatment
works treating domestic sewage) so notified may request an individual permit
under paragraph (b)(3)(iii) of this section.
(3) Requiring an individual permit
(i) The Department may require any discharger
authorized by a general permit to apply for and obtain an alternative general
permit or an individual permit. Any interested person may petition the
Department to take action under this paragraph. A discharger must file an
application for an individual permit within 30 days of receiving a notice from
the Department, unless another time is specified by the Department. Coverage
under the general permit is terminated upon final action by the Department on
an application for an alternative general permit or an individual permit, or if
no application is filed within the time specified by the Department. Cases
where an individual permit may be required include the following:
(A) The discharger or ``treatment works
treating domestic sewage" is not in compliance with the conditions of the
general permit;
(B) A change has
occurred in the availability of demonstrated technology or practices for the
control or abatement of pollutants applicable to the point source or treatment
works treating domestic sewage;
(C)
Effluent limitation guidelines are promulgated for point sources covered by the
general permit;
(D) A Water Quality
Management plan containing requirements applicable to such point sources is
approved;
(E) Circumstances have
changed since the time of the request to be covered so that the discharger is
no longer appropriately controlled under the general permit, or either a
temporary or permanent reduction or elimination of the authorized discharge is
necessary;
(F) [reserved];
or
(G) The discharge(s) is a
significant contributor of pollutants. In making this determination, the
Department may consider the following factors:
(1) The location of the discharge with
respect to waters of the State;
(2)
The size of the discharge;
(3) The
quantity and nature of the pollutants discharged to waters of the State;
and
(4) Other relevant
factors;
(ii)
[reserved]
(iii) Any owner or
operator eligible for coverage under a general permit may request to be
excluded from the coverage of the general permit by applying for an individual
permit. The owner or operator shall submit an application under Chapter 521,
with reasons supporting the request, to the Department no later than 90 days
after issuance of the general permit. The request shall be processed under
Chapter 522. The request shall be granted by issuing of any individual permit
if the reasons cited by the owner or operator are adequate to support the
request.
(iv) When an individual
permit is issued to an owner or operator otherwise subject to a general permit,
the applicability of the general permit to the individual permittee is
automatically terminated on the effective date of the individual
permit.
(v) A source excluded from
a general permit solely because it already has an individual permit may request
that the individual permit be revoked, and that it be covered by the general
permit. Upon revocation of the individual permit, the general permit shall
apply to the source.
