BEST MANAGEMENT PRACTICES or BMPs. Schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to implement the prohibitions listed in § 51.020(A) and (B) (40 CFR 403.5(a)(1) and (b)).

MONTHLY AVERAGE. The sum of all “daily discharges” measured during a calendar month divided by the number of “daily discharges” measured during that month.
MONTHLY AVERAGE LIMIT. 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.
NEW SOURCE.
(1) Any building, structure, facility, or installation from which there is (or may be) a discharge of pollutants, the construction of which commenced after the publication of proposed pretreatment standards under Section 307(c) of the Act that will be applicable to such source if such standards are thereafter promulgated in accordance with that section, provided that:
(a) The building, structure, facility, or installation is constructed at a site at which no other source is located; or
(b) The building, structure, facility, or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or
(c) The production or wastewater generating processes of the building, structure, facility, or installation are substantially independent of an existing source at the same site. In determining whether these are substantially independent, factors such as the extent to which the new facility is integrated with the existing plant, and the extent to which the new facility is engaged in the same general type of activity as the existing source, should be considered.
(2) Construction on a site at which an existing source is located results in a modification rather than a new source if the construction does not create a new building, structure, facility, or installation
meeting the criteria of division (1)(b) or (c) above but otherwise alters, replaces, or adds to existing process or production equipment.
(3) Construction of a new source as defined under this division has commenced if the owner or operator has:
(a) Begun, or caused to begin, as part of a continuous onsite construction program;
1. Any placement, assembly, or installation of facilities or equipment; or
2. Significant site preparation work including clearing, excavation, or removal of existing buildings, structures, or facilities which is necessary for the placement, assembly, or installation of new source facilities or equipment; or
(b) Entered into a binding contractual obligation for the purchase of facilities or equipment which are intended to be used in its operation within a reasonable time. Options to purchase or contracts which can be terminated or modified without substantial loss, and contracts for feasibility, engineering, and design studies do not constitute a contractual obligation under this division.
NONCONTACT COOLING WATER. Water used for cooling that does not come into direct contact with any raw material, intermediate product, waste product, or finished product.
PASS THROUGH. A discharge which exits the POTW into waters of the United States in quantities or concentrations which, alone or in conjunction with a discharge or discharges from other sources, is a cause of a violation of any requirement of the town’s NPDES permit, including an increase in the magnitude or duration of a violation.
PERSON. Any individual, partnership, copartnership, firm, company, corporation, association, joint stock company, trust, estate, governmental entity, or any other legal entity; or their legal representatives, agents, or assigns.

PRETREATMENT. The reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater prior to, or in lieu of, introducing such pollutants into the POTW. This reduction or alteration can be obtained by physical, chemical, or biological processes; by process changes; or by other means, except by diluting the concentration of the pollutants unless allowed by an applicable pretreatment standard.
PRETREATMENT REQUIREMENTS. Any substantive or procedural requirement related to pretreatment imposed on a user, other than a pretreatment standard.
PRETREATMENT STANDARDS or STANDARDS. Prohibited discharge standards, categorical pretreatment standards, and local limits.

SEWAGE. Human excrement and gray water (household showers, dishwashing operations, etc.).
SIGNIFICANT INDUSTRIAL USER (SIU). Except as provided in divisions (3) and (4) below, a significant industrial user is:
(1) An industrial user subject to categorical pretreatment standards; or
(2) An industrial user that:
(a) Discharges an average of 25,000 gpd or more of process wastewater to the POTW (excluding sanitary, noncontact cooling and boiler blowdown wastewater);
(b) Contributes a process wastestream which makes up 5% or more of the average dry weather hydraulic or organic capacity of the POTW treatment plant; or
(c) Is designated as such by the town on the basis that it has a reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement.
(3) Upon a finding that a user meeting the criteria in division (2) of this part has no reasonable potential for adversely affecting the POTW’s operation or for violating any pretreatment standard or requirement, the town may at any time, on its own initiative or in response to a petition received from an industrial user, and in accordance with procedures in 40 CFR 403.8(f)(6), determine that such user should not be considered a significant industrial user.
SLUG LOAD or SLUG DISCHARGE. Any discharge at a flow rate or concentration, which could cause a violation of the prohibited discharge standards in § 51.020. A SLUG DISCHARGE is any discharge of a non-routine, episodic nature, including but not limited to an accidental spill or a non-customary batch discharge, which has a reasonable potential to cause interference or pass through, or in any other way violate the POTW's regulations, local limits or permit conditions.
