                                                SCHEDULE I - DEFINITIONS


  For the purposes of this development approval the following definitions apply:

 (I1)       "mg/L" means milligrams per litre.

 (12)       "composite" in respect of sampling means either time based taken at hourly intervals to cover the
            period in the 24 hours of the sampling day during which a contaminant release occurs; or taken after
            set flow volumes to cover the period of the sampling day during which the contaminant release
            occurs

 (13)       "dry weather day" refers to a day during which no rain falls within the catchment of the sewage
            treatment plant for the commencement of measurement for that day. The term also excludes days
            during which measurement is made which occur within three days following cumulative rainfall of 100
            mm over the four preceding days.

 (14)       "grab" sample means one sample collected at any point in time.

 (15)       "median" means the middle value, where half the data are smaller, and half the data are larger. If the
            number of samples is even, the median is the arithmetic average of the two middle values.

 (16)       "maximum" means that the measured value of the quality characteristic or contaminant must not be
            greater than the release limit stated.

 (17)       "minimum" means that the measured value of the quality characteristic or contaminant must not be
            less than the release limit stated.

 (18)       "50th percentile" - P50 is that value of X, say X50, which corresponds to a cumulative frequency of
            50*N/100, where N is the sample size.

  (19)      "range" means that the measured value of the quality characteristic or contaminant must not be
            greater than the higher release limit stated nor lower than the lower release limit stated.

 (110)      "L(Amax adj,T)" means the average maximum A-weighted sound pressure level, adjusted for noise
            character and measured over a time period of not less than 15 minutes, using Fast response.

 (111)      "background noise level" means either:

                      L (A90,T) being the A-weighted sound pressure level exceeded for 90 percent of the time
                      period not less than 15 minutes, using Fast response, or

                      L (Abg,T) being the arithmetic average of the minimum readings measured in the absence of
                      the noise under investigation during a representative time period of not less than 15 minutes,
                      using Fast response.

 (112)     "noise sensitive place" means -

           (a)        a dwelling, mobile home or caravan park, residential marina or other residential premises; or
           (b)        a motel, hotel or hostel; or
           (c)        a kindergarten, school, university or other educational institution; or
           (d)        a medical centre or hospital; or
           (e)        a protected area; or
           (f)        a park or gardens.

(113)    "commercial place" means a place used as an office or for business or commercial purposes.
