. The following definitions apply to Chapters 521 through 529. Other terms which have specific or limited meaning in the context of a rule are defined in that rule. Terms not otherwise defined have the meaning given by State Law, Title 38, Chapter 3 or the Federal Clean Water Act. When a defined term appears in a definition, the defined term is sometimes placed in quotation marks as an aid to readers. The definitions in Chapters 521 through 529 are not intended in any way to define or affect the meaning of terms used in other rules administered by the Department.
Administrator means the Administrator of the United States Environmental Protection Agency, or an authorized representative.
Act means the Federal Water Pollution Control Act, Federal public law 92-500 or 33 United States Code, sections 1251, et. seq., and including all amendments effective on or before January 1, 1997, of the Clean Water Act.
Applicable standards and limitations means all State, interstate, and federal standards and limitations to which a ``discharge,'' a ``sewage sludge use or disposal practice,'' or a related activity is subject under the CWA, including ``effluent limitations,'' water quality standards, standards of performance, toxic effluent standards or prohibitions, ``best management practices,'' pretreatment standards, and ``standards for sewage sludge use or disposal'' under sections 301, 302, 303, 304, 306, 307, 308, 403 and 405 of CWA.
Application means the forms provided by the Department for applying for a permit, including any additions, revisions or modifications to the forms.
Approved program or approved State means a State or interstate program which has been approved or authorized by EPA under 40 CFR part 123.
Average monthly discharge limitation means the highest allowable average of ``daily discharges'' over a calendar month, calculated as the sum of all ``daily discharges'' measured during a calendar month divided by the number of ``daily discharges'' measured during that month. Except, however, bacteriological tests may be calculated as a geometric mean.
Average weekly discharge limitation means the highest allowable average of ``daily discharges'' over a calendar week, calculated as the sum of all ``daily discharges'' measured during a calendar week divided by the number of ``daily discharges'' measured during that week.
Best management practices (``BMPs'') means schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce the pollution of ``waters of the State.'' BMPs also include treatment requirements, operating procedures, and practices to control plant site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.
BMPs means ``best management practices.''
Commissioner means the Commissioner of the Department of Environmental Protection, or his or her designee.
Contiguous zone means the entire zone established by the United States under Article 24 of the Convention on the Territorial Sea and the Contiguous Zone.
Continuous discharge means a ``discharge'' which occurs without interruption throughout the operating hours of the facility, except for infrequent shutdowns for maintenance, process changes, or other similar activities.

CWA and regulations means the Clean Water Act and applicable regulations promulgated thereunder, including State program requirements.
Daily discharge means the ``discharge of a pollutant'' measured during a calendar day or any 24-hour period that reasonably represents the calendar day for purposes of sampling. For pollutants with limitations expressed in units of mass, the ``daily discharge'' is calculated as the total mass of the pollutant discharged over the day. For pollutants with limitations expressed in other units of measurement, the ``daily discharge'' is calculated as the average measurement of the pollutant over the day.
Department means the Department of Environmental Protection, including the Board of Environmental Protection and the "Commissioner".
Director means the Regional Administrator or the "Department", as the context requires, or an authorized representative. ``Director'' normally means the Department. In some circumstances, however, EPA retains the authority to take certain actions even when there is an approved State program. (For example, when EPA has issued an NPDES permit prior to the approval of a State program, EPA may retain jurisdiction over that permit after program approval, see 40 CFR 123.1.) In such cases, the term "Director'' means the Regional Administrator and not the Department.
Discharge means any spilling, leaking, pumping, pouring, emptying, dumping, disposing or other addition of any pollutant to "waters of the State".

DMR means ``Discharge Monitoring Report.''
Draft permit means a document prepared under Chapter 522 indicating the Department's tentative decision to issue or deny, modify, revoke and reissue, terminate, or reissue a ``permit.'' A notice of intent to terminate a permit, and a notice of intent to deny a permit, as discussed in Chapter 522, are types of ``draft permits.'' A denial of a request for modification, revocation and reissuance, or termination, as discussed in Chapter 522, is not a ``draft permit.'' A ``proposed permit'' is not a ``draft permit.''

National Pollutant Discharge Elimination System (NPDES) means the national program for issuing, modifying, revoking and reissuing, terminating, monitoring and enforcing permits, and imposing and enforcing pretreatment requirements, under sections 307, 402, 318, and 405 of CWA. The term includes an ``approved program.''
New discharger means any building, structure, facility, or installation:
This definition includes an ``indirect discharger'' which commences discharging into ``waters of the State'' after August 13, 1979. It also includes any existing mobile point source (other than an offshore or coastal oil and gas exploratory drilling rig or a coastal oil and gas developmental drilling rig) such as a seafood processing rig, seafood processing vessel, or aggregate plant, that begins discharging at a ``site'' for which it does not have a permit; and any offshore or coastal mobile oil and gas exploratory drilling rig or coastal mobile oil and gas developmental drilling rig that commences the discharge of pollutants after August 13, 1979, at a ``site'' under EPA's permitting jurisdiction for which it is not covered by an individual or general permit and which is located in an area determined by the Regional Administrator in the issuance of a final permit to be an area or biological concern. In determining whether an area is an area of biological concern, the Regional Administrator shall consider the factors specified in 40 CFR 125.122(a) (1) through (10).
An offshore or coastal mobile exploratory drilling rig or coastal mobile developmental drilling rig will be considered a ``new discharger'' only for the duration of its discharge in an area of biological concern.
