Water Quatity Standards
The proposed water quality standards are based upon the following assumptions:

the project is smali scale development

the duration of exposure is short

the risk of ponded water developing is very iow

the need to discharge groundwater is not expected

the water quality objectives wilt control pH and solubte metals for most receiving environments
the suspended solids and turbidity standards are achievable for a smalt scale construction
activities where-as more stringent standards (whilst desirable) will be difficult and may be
impossible to implement

the level of mixing and dilution in the receiving waters for any small scale, short term discharge
will be very high and the probable effect on the receiving environment will be very small to the
point of being immeasurable.
