    BB.

    "Interference" - A discharge which causes (either by itself or in combination with other discharges) a violation of the City's NPDES permit or prevents the intended sewage sludge use or disposal by inhibiting or disrupting the POTW, including its collection systems, pump stations, and wastewater and sludge treatment processes. An example is a discharge from a user which causes a blockage resulting in a discharge at a point not authorized under the City's NPDES permit.

    CC.

    "Local limits" - Effluent limitation developed for users by the director to specifically protect the POTW from the potential of pass through, interference, vapor toxicity, explosions, sewer corrosion, and contaminations of biosolids. Such limits shall be based on the POTW's site-specific flow and loading capacities, receiving water considerations, and reasonable treatment expectations for non-domestic wastewater.

    DD.

    "May" - Is permissive (see "shall").

    1.

    Have some discharges of wastewater that could cause detectably elevated concentrations of metals or toxics in the pretreatment quarterly analysis; or

    2.

    Have a discharge of small quantities of dangerous waste to the POTW which have been excluded from regulation under Chapter 173-303 WAC, or its successors, through the domestic sewage exclusion; or

    3.

    Have a potential to discharge or spill chemicals to the POTW.

    GG.

    "Monthly average" - The arithmetic mean of the effluent samples collected during a calendar month or specified 30-day period. Where the control authority has taken a sample during the period, it must be included in the monthly average if provided in time. However, where composite samples are required, grab samples taken for process control or by the control authority are not to be included in a monthly average.

    HH.

    "Monthly average limit" - The limit to be applied to the monthly average to determine compliance with the requirements of this chapter (see section 13.06.045 for listing).

    II.

    JJ.

    "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), or its successors, of the Act which 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 subsections (1)(b) or (c) above, but otherwise alters, replaces, or adds to existing process or production equipment.

    3.

    Construction of a new source has commenced if the owner or operator has:

    2.

    Have no discharge of dangerous waste to the POTW which have been excluded from regulation under Chapter 173-303 WAC, or its successors, through the domestic sewage exclusion; and
