Current through Register Vol. 54, No. 28, July 13, 2024
The following words and terms, when used in this
						  chapter, have the following meanings, unless the context clearly indicates
						  otherwise:
Average daily organic load
-The
						  arithmetic mean of all samples of 5-day Biochemical Oxygen Demand, expressed in
						  terms of pounds per day, collected over a calendar month.
Ban
-A restriction placed by the
						  Department on additional connections to an overloaded sewer system or a sewer
						  system tributary to an overloaded plant and other necessary measures the
						  Department may require to prevent or alleviate an actual organic or hydraulic
						  overload or an increase in an organic or hydraulic overload.
Bypass
-The intentional diversion of
						  wastewater either at or after the headworks of the plant.
CAP-Corrective action plan
-A plan and
						  schedule developed by the permittee of a sewerage facility which has an
						  existing or projected overload. A CAP establishes actions needed and a schedule
						  to reduce the overload and provide needed capacity.
CSO-Combined sewer overflow
-An
						  intermittent overflow, or other untreated discharge from a municipal combined
						  sewer system (including domestic, industrial and commercial wastewater and
						  stormwater) which results from a flow in excess of the dry weather carrying
						  capacity of the system.
Capacity
-The rated ability of the
						  plant to receive and effectively treat a specified load. When the term is used
						  in reference to a pump station or sewer system, the term refers to the rated
						  ability to effectively convey a specified load.

Combined sewer system
-A sewer system

						  sewer.
Connection
-The connection of a
						  structure which generates or could generate hydraulic or organic loads to a
						  sewer system.
Discharge
-Wastewater flow which is or
						  would be discharged to a sewer system.
Exception to a ban
-An allowable

Headworks
-For the purposes of this
						  chapter, the first treatment unit or wetwell within the plant.
Hydraulic design capacity
-The maximum
						  monthly design flow, expressed in millions of gallons per day, at which a plant
						  is expected to consistently provide the required treatment or at which a
						  conveyance structure, device or pipe is expected to properly function without
						  creating a backup, surcharge or overflow. This capacity is specified in the
						  water quality management permit (Part II permit issued under Chapter 91)
						  (relating to general provisions).
Hydraulic overload
-The condition that
						  occurs when the monthly average flow entering a plant exceeds the hydraulic
						  design capacity for 3-consecutive months out of the preceding 12 months or when
						  the flow in a portion of the sewer system exceeds its hydraulic carrying
						  capacity.
Industrial user
-An establishment which
						  discharges or introduces industrial wastes into a sewerage facility.
Interference
-A discharge which, alone
						  or in conjunction with a discharge from other sources, does the
						  following:
(i) Inhibits or disrupts
						the sewerage facility, its treatment processes or operations or its sludge
						processes, use or disposal.
(ii) Is
						a cause of a violation of a requirement of the sewerage facility's NPDES
						permit-including an increase in the magnitude or duration of a violation-or of
						the prevention of sewage sludge use or disposal in compliance with the
						following statutory provisions and regulations or permits issued thereunder-or
						more stringent State or local regulations:
(A)
						Section 405 of the Clean Water Act (33 U.S.C.A. §
														1345).
(B) The Solid Waste Disposal Act (SWDA)
						(42 U.S.C.A. §§
														6901-6987), including Title II, more
						commonly referred to as the Resource Conservation and Recovery Act of 1976
						(RCRA).
(C) State regulations
						contained in a State sludge management plan prepared under Subtitle D of the
						SWDA, the Clean Air Act (42
						U.S.C.A. §§
														7401-7642),
						the Toxic Substances Control Act (15 U.S.C.A. §§
														2601-2629) and the Marine Protection,
						Research, and Sanctuaries Act of 1972 (16 U.S.C.A. §§
														1431-1434;
