Part 1—Air pollutants emitted from a stationary source
1.01 Definitions
(1) In Table 1:
Bacharach, followed by a number, means the unit of measurement represented by that number under the system of measurement provided by Bacharach equipment.
gaseous emission means an emission of a gas or vapour, whether or not it carries suspended liquid or solid matter.
ICP standard method means the method of estimation of metal particles in air, known as the inductive coupled plasma method and set out in Australian Standard AS 2800.
Ringelmann, followed by a number, means the unit of measurement represented by that number under the system of measurement provided by Ringelmann equipment.
volatile organic liquid means:
(a) crude oil; or
(b) crude petroleum; or
(c) a liquid suitable for use as fuel for a spark‑ignition engine; or
(d) a liquid consisting of more than 50% by volume of heptene, toluene, trichlorethylene, xylene, or any mixture of those substances;
but does not include kerosene, jet fuel, or tractor vaporising oil.
Meaning of 12% CO2 reference level
(2) If the expression 12% CO2 reference level appears in column 4 of an item in Table 1, the level in exhaust or combustion gas of the pollutant referred to in the item is taken to be the level that would be in the gas if the gas contained 12% CO2 by volume.
Meaning of concentration of NO2
(3) In Table 1, mention of a concentration of NO2 at a particular oxygen reference concentration is a mention of the measured concentration of NO2 adjusted in accordance the following formula:
Start formula measured NO start subscript 2 end subscript concentration times start fraction open bracket 21 minus ROC close bracket over open bracket 21 minus MOC close bracket end fraction end formula
where:
measured NO2 concentration means the measured concentration of oxides of nitrogen, expressed as NO2.
MOC means the measured oxygen concentration.
ROC means the particular oxygen reference concentration.
Accepted limits—measurement assumptions
(4) In Table 1, the expression, in column 4 of Table 1, of a volume of gas or vapour assumes the gas or vapour to be measured dry, at a temperature of 0 C. and at an absolute pressure of one atmosphere (101.325 kPa).
Measurement of rate of emission
(5) For Table 1, the rate of emission of a substance is assumed to be ascertained:
(a) unless the contrary intention appears, by measurement of samples:
(i) at, or taken from, the point of emission into the air; and
(ii) that are undiluted; and
(b) in accordance with the method of measurement, analysis or monitoring mentioned for the substance in column 5.

The ambient objective for a substance mentioned in column 2 of table 2 is that concentrations of the substance in air at an airport, measured over the period of time mentioned in column 3, do not exceed the averaged concentration mentioned in column 4.
Note: The goals for photochemical oxidants assume measurement of ozone only (the major constituent of photochemical oxidant).
Schedule 2—Water pollution—accepted limits
(subregulation 2.02(3) and paragraph 4.02(a))
1.01 Interpretation
In this schedule:
fresh water means water containing total dissolved solids of less than 1000 mg/l, and includes any water of that quality in a pipe, drain or man‑made channel delivering water for use by humans or animals.
MPN/100ml means most probable number of coliform count per 100 millilitres.
marine water means ocean, sea, coastal or estuarine water, and includes river water affected by the tide.
seasonal mean TSS means the mean total of suspended solids for a climatic season, calculated in accordance with methodology acceptable to an airport environment officer for the airport concerned, taking into account the climatic and topographic conditions of the locality in which the airport is located.
waters has the same meaning as it has in regulation 2.02.

(2) There is an adverse effect if, because of the entry of a substance into waters, the dissolved‑oxygen content of the waters falls:
(a) below 6 mg/l; or
(b) to 80% of the average saturation level for a normal 24 hour period.
pH
(3) There is an adverse effect if, because of the entry of a substance into waters, the pH of the waters:
(a) for fresh water—falls below 6.5, or rises above 9.0; or
(b) for marine water—rises by more than 0.2 pH unit.
Salinity
(4) There is an adverse effect if, because of the entry of a substance into waters:
(a) the salinity of the water rises above 1000 mg/l; or
(b) the salinity rises by more than 5%.
Turbidity
(5) There is an adverse effect if, because of the entry of a substance into waters:
(a) the TSS (total suspended solids) of the waters changes by more than 10% from the seasonal mean TSS; or
(b) visual clarity within the euphotic zone is reduced by more than 10% from the seasonal mean clarity.
Faecal coliforms
(6) There is an adverse effect if, because of the entry of a substance into waters:
(a) the median faecal coliform count of test samples of the waters exceeds 150 faecal coliform organisms/100 ml; and
(b) the faecal coliform count of more than 20% of at least 5 test samples of the waters, taken at regular intervals during a period no longer than 1 month, exceeds 600 faecal coliform organisms/100ml.
Temperature
(7) There is an adverse effect if, because of the entry of a substance into waters, the temperature of the waters rises by more than 2º C above the seasonal mean temperature.

Schedule 4—Excessive noise—guidelines
(subregulation 2.04(2) and paragraphs 4.07(a) and (b))
Part 1—Introductory
1.01 Purpose of Schedule
For subregulation 2.04(2) of the Regulations, this Schedule sets out indicators of noise that is excessive.
Note: Generation of excessive noise is not, of itself, an offence under the Regulations.
1.02 Interpretation
In this Schedule:
average maximum A‑weighted sound pressure level has the same meaning as it has in Australian Standard AS 1055.
A‑weighted sound pressure level has the same meaning as it has in Australian Standard AS 1055.
background noise level, at a particular place, means the level of noise, calculated as the A‑weighted sound pressure level measured at that place, using time weighting ‘F’, that is exceeded for 90% of a period of at least 15 minutes.
equivalent continuous A‑weighted sound pressure level has the same meaning as it has in Australian Standard AS 1055.
time weighting ‘F’ has the same meaning as it has in Australian Standard AS 1259.
Part 2—Sensitive receptors
2.01 Application
This Part applies to sites of sensitive receptors, and a reference in a provision of this Part to a sound pressure is a reference to sound pressure audible at the site of a sensitive receptor.
2.02 Noise from construction, etc
(1) Noise generated from construction, maintenance or demolition of a building or other structure at an airport should not exceed 75 dB(A), calculated in accordance with subclause (2), at the site of a sensitive receptor.
(2) For subregulation (1), the sound pressure level of a particular noise is the sound pressure level that is exceeded for 10% of a period of at least 15 minutes, adjusted to take account of tonal character and impulsiveness (if any) of the noise.
2.03 Noise from road traffic
Noise generated from road traffic on the site of an operator of an undertaking at an airport should not exceed:
(a) 60 dB(A), calculated as the equivalent continuous A‑weighted sound pressure level for a 24 hour period of measurement; and
(b) 55 dB(A), calculated as the equivalent continuous A‑weighted sound pressure level for an 8 hour period of measurement from 22:00 hours on a particular day to 06:00 hours on the following day.
2.04 Noise from rail traffic
Noise generated from rail traffic operated at an airport should not exceed:
(a) 87 dB(A), calculated as the average maximum A‑weighted sound pressure level for a period of at least 15 minutes measurement; and
(b) 60 dB(A), calculated as the equivalent continuous A‑weighted sound pressure level for a 24 hour period of measurement; and
(c) 55 dB(A), calculated as the equivalent continuous A‑weighted sound pressure level for an 8 hour period of measurement from 22:00 hours on a particular day to 06:00 hours on the following day.
2.05 Noise from ground‑based aircraft operations
(1) For ground‑based aircraft operations, there are no indicators of noise that is excessive, but the following considerations apply in determining whether noise is excessive.
(2) Noise from ground‑based aircraft running for any reason should only be generated in a manner that is consistent with:
(a) within 1 year after the airport at which the ground running is being conducted is first leased—guidelines for ground running published by the Federal Airports Corporation and in effect when these Regulations are made; or
(b) at a time after 1 year after the airport is first leased—express provision in the final master plan for the airport.
(3) In relation to other ground‑based operations and in relation to ground‑based aircraft running at times other than a time to which subclause (2) applies, matters to be considered are:
(a) the distance between the source of the noise and the site of the sensitive receptor; and
(b) the background noise level;
(c) the time of day when the noise occurs; and
(d) if the noise source is an aircraft engine—the power setting of the engine;
(e) anything included in the final master plan (if any) for the airport at which ground running is being conducted that is relevant to this clause.
(3A) This clause applies to noise generated from ground‑based aircraft running at Sydney West Airport before the first final master plan is in force for that airport as if:
(a) the words “express provision in the final master plan” were omitted from paragraph (2)(b); and
(b) the words “the conditions in an airport plan” were substituted in paragraph (2)(b); and
(c) the words “final master plan (if any)” were omitted from paragraph (3)(e); and
(d) the words “conditions in an airport plan” were substituted in paragraph (3)(e).
(4) In this clause:
ground‑based aircraft operations means:
(a) operation of an auxiliary power unit of an aircraft; or
(b) ground‑based aircraft running; or
(c) test‑bed running of an aircraft engine removed from an aircraft.
ground‑based aircraft running means test operation of an engine attached to an aircraft.
2.06 Noise from other airport operations
(1) This clause applies to noise generated from any of the following activities:
(a) aircraft refuelling;
(b) activities in connection with aircraft that do not involve the operating of an aircraft engine (for example, moving, maintaining or repairing aircraft);
(c) operation of plant or machinery;
(d) assembling of passengers or goods in connection with embarkation or disembarkation of aircraft;
(e) operation of fixed audible alarm or warning systems.
(2) Noise generated from an activity mentioned in subclause (1) should not exceed the background noise level at the sensitive receptor site:
(a) between the hours of 07:00 and 22:00—by more than 5 dB(A); and
(b) between 22:00 hours of a day and 07:00 hours of the next day—by more than 3 dB(A).
(3) For subregulation (2), the sound pressure level of a particular noise is the sound pressure level that is exceeded for 10% of a period of at least 15 minutes, adjusted to take account of tonal character and impulsiveness (if any) of the noise.
Part 3—Commercial receptors
3.01 Application
This Part applies to sites of commercial receptors, and a reference in a provision of this Part to a sound pressure is a reference to sound pressure measurable at the site of a commercial receptor.
3.02 Noise from any source
For sites of commercial receptors, the indicators of noise that is excessive are the indicators mentioned for sites of sensitive receptors, but the following considerations also apply in determining whether noise is excessive at a particular site:
(a) the nature of the business conducted at the site;
(b) the time of day when the noise occurs;
(c) the duration of the noise;
(d) the nature and characteristics (if any) of the noise;
(e) the background noise level.
Part 4—Measuring noise
4.01 Procedures and standards
(1) This clause sets out the procedures and standards to be applied by an airport environment officer in measuring noise for the purposes of the regulations.
Procedure
(2) In making a measurement, an airport environment officer must do so:
(a) at the most affected site of sensitive receptor, or commercial receptor, as the case requires; and
(b) by a procedure that is in accordance with:
(i) the relevant Australian Standard (if any) as in force at the commencement of these regulations; or
(ii) if a procedure is detailed in the final master plan (if any) for the airport concerned—that procedure; or
(iii) if neither paragraph (a) or (b) apply—a relevant procedure published by the International Organisation for Standardisation (if any), as in force at the commencement of these Regulations.
(2A) Paragraph (2)(b) applies to a measurement of noise generated at, over or under Sydney West Airport before the first final master plan is in force for that airport as if:
(a) the words “detailed in the final master plan (if any)” were omitted from subparagraph (ii) of that paragraph; and
(b) the words “required by the conditions in an airport plan” were substituted.
Construction of buildings, etc
(3) The standard to be applied in determining the level of noise generated from construction, maintenance or demolition of a building or other structure at an airport is Australian Standard AS 1055.
Road traffic
(4) The standard to be applied in determining the level of noise generated from particular road traffic at an airport is Australian Standard AS 2702.
Rail traffic
(5) The standard to be applied in determining the level of noise generated from particular rail traffic at an airport is Australian Standard AS 2377.
Ground‑based aircraft operations
(6) The standard to be applied in determining the level of noise generated from particular ground based aircraft operations at an airport is Australian Standard AS 1055.
Other airport operations
(7) The standard to be applied in determining the level of noise generated from an activity mentioned in subclause 2.06(1), at an airport, is Australian Standard AS 1055.
