The department may issue general WPDES permits applicable to designated areas of the state authorizing discharges from specified categories or classes of point sources located within those areas.
Designated areas of the state may include any of the following:
Any county, township, city or other civil or political division.
Categories or classes which may be covered by general permit are those where point sources:
Employ the same or substantially similar wastewater treatment operations to control specific pollutants;
Are subject to the same effluent limitations and monitoring requirements; and
In the opinion of the department, are more appropriately controlled under a general permit than under individual permits.
NR 205.08 Note
Section NR 210.20
requires permit authorization for all satellite sewage collection systems.
General permit issuance shall be subject to the public notice and hearing procedures of subs. (8)
General permits shall have effective terms to a maximum of 5 years from the date of issuance.
A general permit may cover more than one class or category of discharge, or more than one area of the state, provided the permit clearly identifies the conditions applicable to each included class or category, or each specific area of the state. General permits may contain effluent limitations, monitoring requirements, reporting requirements, general conditions and applicability criteria.
Individual dischargers are not required to submit formal WPDES permit applications to be eligible for coverage under a general permit. On a case-by-case basis the department may by letter require a discharger to submit information regarding a wastewater discharge which is to be covered by a general permit. On a case-by-case basis the department may by letter require a discharger to submit a notice of intent to be covered by a general permit. Following receipt of a complete notice of intent the department shall issue a determination on whether a discharger is covered by a general permit.
The department shall withdraw a point source from coverage by a general permit and issue an individual permit upon written request of the discharger.
The department may require any point source covered by a general permit to apply for and obtain an individual permit. Any person may submit a written request that the department take action under this subsection. Situations in which an individual permit may be required include:
The point source is a significant contributor of pollution or the point source is more appropriately regulated by an individual permit;
The point source is not in compliance with the terms and conditions of the general permit;
A change occurs in the availability of demonstrated technology or practices for the control or abatement of pollutants from the point source or class of discharger;
Effluent limitations or standards are promulgated for a point source or class of point sources covered by the general permit and are different than the conditions contained in the general permit;
A water quality management plan containing requirements applicable to the point source is approved.
When an individual WPDES permit is issued for discharges which would otherwise be covered by a general permit, the applicability of the general permit to such discharges is terminated on the effective date of the individual permit.
An owner or operator who holds an individual WPDES permit for discharges which are eligible for coverage by a general permit may request that the department revoke the individual permit.
Any general permit issued by the department may, after an opportunity for hearing, be modified, revoked and reissued, or terminated. Whenever the department finds there is a need to modify, revoke and reissue, or terminate a general permit, a public notice shall be made allowing 30 days for public comment prior to the intended date of final action. Any public notice shall:
Be published as a class 1 notice under ch. 985, Stats.
, in all counties where dischargers may be located, or in the official state newspaper as defined in s. 985.04
, Stats., and on the department's Internet Web site.
Be mailed to any person, group, agency or unit of government upon request.
Contain a description of the discharge types or categories or classes of dischargers covered by the general permit.
Identify the waters of the state and areas of the state to which the general permit is applicable.
Identify how and where to obtain additional information, submit written comments or request a public informational hearing.
Describe the procedures to be used to formulate a final determination on the proposed action.
Be distributed for comment to the U.S. environmental protection agency, the U.S. army corps of engineers, U.S. fish and wildlife service, and other states potentially affected by the discharges. This subsection shall only apply to general permits which authorize discharges to surface waters.
Be distributed to any county and regional planning commission in any area of the state where discharges under the general permit may be authorized.
Be mailed to all facilities known by the department to be covered by a general permit in the case of termination of a general permit to a class or category of discharge.
To satisfy the mailing requirement of this of this section the department may either send a paper copy of the document in the US mail, or transmit the document electronically by email, provided the person or group does not object to electronic mailing. The document mailed may reference the department's Internet Web site where additional referenced material can be accessed.
General permits may be reissued following public notice and opportunity for hearing. The public notice procedures of sub. (8)
shall apply to general permit reissuance. Whenever possible, the department shall reissue general permits prior to the expiration date of the previous general permit to prevent the possibility of dischargers being unpermitted. Even though dischargers under a general permit are not required to submit an application for reissuance, the provisions of s. 227.51 (2)
, Stats., shall apply as though an application had been submitted by the class or category of dischargers covered by the permit.
If the department intends to terminate the coverage of a general permit to a class or category of discharger upon the expiration of the general permit, the action shall follow the procedural requirements under sub. (8)
The department shall hold public informational hearings on any proposed general permit issuance, reissuance, modification, revocation and reissuance, or termination if the department determines that there is significant public interest in holding a hearing or upon the petition of 5 or more persons. Petitions shall indicate the interest of the petitioners and the reasons why a hearing is warranted. Requests for hearings under this section shall be submitted so that the requests will be received by the department during the 30-day comment period provided by the public notice of the proposed action.
Public notice of any hearing held under this section shall be made in accordance with the requirements of sub. (8)
Hearings shall be held at locations which are most convenient geographically to the largest number of petitioners.
Procedures for the appearance at, and conduct of, hearings held under this section shall be in accordance with ss. NR 203.08
The department shall make a final determination on the proposal to issue, reissue, modify, revoke and reissue, or terminate a general permit based upon the consideration of statements by the public, government agencies and any other pertinent information. A notice of final determination shall be prepared and circulated in accordance with s. NR 203.13
